    Full Text Available Objectives: The use of nicotine through smoking remains a serious health problem. It has been associated with reduced fertility, although the mechanism responsible is still unclear. The present study was designed to investigate whether nicotine-induced infertility is associated with altered male reproductive hormones in male albino rats. Materials and Methods: Forty male rats were divided equally into five groups and treated orally for thirty days. Group I, which served as the control received 0.2 ml/kg normal saline, Group II and III received 0.5 mg/kg (low dose and 1.0 mg/kg (high dose body weight of nicotine, respectively. The fourth and fifth groups were gavaged with 0.5 mg/kg and 1.0 mg/kg body weight of nicotine but were left untreated for another 30 days. These groups served as the recovery groups. Serum was analyzed for testosterone, luteinizing hormone (LH, follicle stimulating hormones (FSH, and prolactin using radioimmunoassay. Results: Results showed that nicotine administration significantly decreased (P < 0.05 testosterone in the low and high treated groups and FSH in the high dose treated group when compared with the control group. There was a significant increase (P < 0.05 in mean LH and prolactin level in the high dose treated group when compared with the control. However, the values of the recovery groups were comparable with the control. Conclusion: The findings in this study suggest that nicotine administration is associated with distorted reproductive hormones in male rats although ameliorated by nicotine cessation. It is plausible that the decreased testosterone level is associated with testicular dysfunction rather than a pituitary disorder.

    Full Text Available The present study reflects the effect of ethanolic extract of Capparis aphylla (Roth. on male reproduction and fertility in adult albino rat. The result revealed that the administration of whole plant ethanolic extract of C. aphylla manifested an antifertility effect on male reproductive system. The complete loss of fertility is attributed to decline in epididymal sperm counts and motility as well as origin of bi- and multinucleate giant cells in the ad luminal compartment of the testis was observed. The administration of ethanolic extract at varied doses led to alteration in both the histoarchitecture of testis, mainly caput epididymis and erratic spermatogenesis have been documented. The data revealed that functional sterility could be induced in male rats by whole plant ethanolic extract treatment, which promises to be a potential male contraceptive.

    International Nuclear Information System (INIS)

    Lead (heavy metal) was given as lead acetate for two groups of adult male albino rats (Rattus rattus) in drinking water at dose level of 100 mg/litre for 3 and 6 weeks to evaluate its toxic effects on protein and its fractions by using electrophoresis technique, serum testosterone using radioimmunoassay and histological investigation of the testis of male rats.Administration of 100 mg/L lead acetate in drinking water for 3 and 6 weeks induced fluctuated changes in serum total proteins, protein fractions and significant decrease in serum testosterone hormone.Histopathological examination showed cellular changes and degeneration of the seminiferous tubules after 3 and 6 weeks of administration of lead acetate.The treatment of rats with antox (10 mg/kg) during the experimental period caused improvement in protein fraction and testosterone level, and the testes sections appeared more or less normal.

  10. The Protective Role of Ginger (Zingiber Officinales ) in Male Albino Rats Exposed to Gamma Irradiation

    International Nuclear Information System (INIS)

    The present work was performed to evaluate the effectiveness of preirradiation treatment with ginger (Zingiber Officinales) for 21 consecutive days before exposure in controlling post-irradiation hazards in male rats. Male albino rats weighing about 120±10 g were divided into four groups: ( I ) control, ( II ) treated with ginger 200 mg/kg , ( III ) irradiated with 6 Gy and ( IV ) treated with ginger 200 mg/kg before irradiated with 6 Gy gamma - radiation . The blood samples were collected from heart of animals 21 days after treatment with ginger and seven days post irradiation. Blood samples were subjected to biochemical analysts such as liver functions , lipid profile , kidney function and sex hormone. Whole body gamma irradiation of rats at 6 Gy (single dose) caused significant increase in (aspartate and alanine aminotransferases (AST and ALT), cholesterol, triglycerides , glucose, urea and creatinine) while alkaline phosphatase showed no effect. Irradiation caused decrease in the contents of total protein , albumin and testosterone. Ginger treatment exerted noticeable amelioration in the studied biochemical parameters of the irradiated albino rats. The mechanism of action of ginger may be due to its antiinflammatory properties against whole body gamma irradiation

    Kumar, D.; Bansal, Anju; Thomas, Pauline; Sairam, M.; Sharma, S. K.; Mongia, S. S.; Singh, R.; Selvamurthy, W.

    High altitude stress leads to lipid peroxidation and free radical formation which results in cell membrane damage in organs and tissues, and associated mountain diseases. This paper discusses the changes in biochemical parameters and antibody response on feeding glutamate to male albino Sprague Dawley rats under hypoxic stress. Exposure of rats to simulated hypoxia at 7576 m, for 6 h daily for 5 consecutive days, in an animal decompression chamber at 32+/-2° C resulted in an increase in plasma malondialdehyde level with a concomitant decrease in blood glutathione (reduced) level. Supplementation of glutamate orally at an optimal dose (27 mg/kg body weight) in male albino rats under hypoxia enhanced glutathione level and decreased malondialdehyde concentration significantly. Glutamate feeding improved total plasma protein and glucose levels under hypoxia. The activities of serum glutamate oxaloacetate transaminase (SGOT) and serum glutamate pyruvate transaminase (SGPT) and the urea level remained elevated on glutamate supplementation under hypoxia. Glutamate supplementation increased the humoral response against sheep red blood cells (antibody titre). These results indicate a possible utility of glutamate in the amelioration of hypoxia-induced oxidative stress.

    International Nuclear Information System (INIS)

    The aim of the study was to evaluate the potential benefits of dietary supplementation of eggplant (Solanum melongena) as antioxidant against ?- rays-induced biochemical changes in male albino rats by estimating some of the components of antioxidant defense in the; liver glutathione content (GSH), superoxide dismutase activity (SOD) and malondialdehyde (MDA), serum aspartate amino transferase,(AST), alanine amino transferase (ALT), alkaline phosphatase (ALP), gamma glutamyl transaminase (GGT), cholesterol, triglycerides, low density lipoprotein cholesterol (LDL-C) and high density lipoprotein cholesterol(HDL-C). Male albino rats (120-150 g) were divided into four groups as Control group, group 2 received diet supplemented with 10% of eggplant (Solanum melongnea) fruit for 21 successive days , group 3: irradiated with a single dose (6.5 Gy), group 4 received eggplant for 21 successive days then exposed to 6.5 Gy. All animals were sacrificed after 1, 3 and 8 days post irradiation. Rats exposed to ?-rays exhibited a profound elevation of AST, ALT, ALP and GGT activities, and lipid abnormalities .Noticeable drop in liver GSH content and SOD activity associated with increase of MDA was recorded. Treatment with dietary eggplant for 21 days before irradiation significantly abolished radiation induced elevations in MDA and significantly elevates hepatic GSH content and SOD activity. The levels of cholesterol, TG, HDL-C, LDL-C as well as the activities of AST, ALT, and GGT in serum were significantly ameliorated and noticeable improvement in the lipid profile levels

    Full Text Available Objectives: The study aims to estimate the change in the weight of testis, sperm count, sperm morphology, testicular cholesterol and protein level in acute and chronic traffic noise exposed albino rats. Background: Road traffic is a significant source of noise pollution, a type of environmental stress. Traffic noise significantly increases adrenal cortical function and causes testicular dysfunction. Method: Experiment was performed on adult male albino rats. Animals were divided in to one control group and two experimental groups. Both the experimental groups were exposed to traffic noise having intensity 80 dB to 90 dB at the rate of 5 hr daily and control group was not exposed. First experimental group was exposed to traffic noise for 30 days and second group for 60 days. Testicular weight, sperm count, sperm morphology, testicular protein level and testicular cholesterol level were estimated. Statistical analysis was done using unpaired ‘t’ test. Result: Contribution of testis to body weight, testicular protein level and sperm count were low but testicular cholesterol level was more in traffic noise exposed rats than unexposed counterpart. Traffic noise exposure also increased percentage of morphologically abnormal sperm. Conclusion: Traffic noise adversely affect male gamete and such effect may be due to noise-induced suppression of testosterone synthesis.

  16. Possible Outcome of Fenugreek Seeds Powder Administration on the Fertility of Female and Male Albino Rat

    International Nuclear Information System (INIS)

    Fenugreek (Trigonella foenum-graecum) is an annual plant from the family of Papilionaceae-Leguminosae that has been credited with many medicinal properties. The current study aims to evaluate the possible fertility activity of fenugreek seeds powder on female and male albino rats. To achieve the theme, fenugreek seeds powder (200 mg/rat) were daily administered orally to both female and male Wistar rats for 15 and 30 consecutive days, after which the rats were sacrificed for both biochemical and histopathological observations. Fenugreek treatment significantly decreased the serum cholesterol levels in both female and male rats with a marked increase in the ovary and testis cholesterol levels following 30 days of consecutive administration. The circulating serum female hormones showed an initial elevation at the end of 15 days of fenugreek intake followed by a significant drop in the group of rats that continued to receive the daily fenugreek dose for 30 days. These observations were supported by the notable decline in the ovarian weights further validated by their ovarian histological sections revealing remarkable dissolution of some follicles and prominent abundance of inflammatory cells. In the 30 days interval treated males, the serum testosterone hormone concentrations significantly declined and the testis weights were reduced with evident damage to the seminiferous tubules and interstitial tissues as shown by the histopathological picture of testis tissue sections. Accordingly, it can be deduced that fenugreek seeds powder exert a significant antifertility adverse effect on the female and male rats when supplemented at a considerable dose for an extended time interval

    International Nuclear Information System (INIS)

    Nigella sativa (NS), commonly known as black seed, is a plant spices in which thymoquinone is the main active ingredient isolated from the black seeds. The seeds of Nigella sativa are used in herbal medicine all over the world for the treatment and prevention of a number of diseases. The aim of this study was focused on investigating the possible protective effect of NS against gamma radiation induced nephrotoxicity and inflammatory changes in male albino rats. Twenty four albino rats were divided into four equal groups as follows: control group, irradiated group (animals subjected to whole body gamma irradiation at a dose of 6 Gy), treated group (rats treated with 0.2 ml/kg, i.p., NS oil for 4 weeks), and treated irradiated group (animals treated with 0.2 mL/kg, i.p., NS oil for 4 weeks then exposed to whole body gamma irradiation at a dose of 6 Gy). The obtained results revealed that the administration of Nigella sativa oil to irradiated rats significantly ameliorated the changes induced in kidney antioxidant system; catalase and glutathione peroxidase activities as well as reduced glutathione concentration. Also, NS oil restored the kidney function indices (urea and creatinine) near normal level when compared with their equivalent values in irradiated rats. In addition, the changes in serum tumor necrosis factor alpha (TNF-?), Interleukin-1? (IL-1?) and Interleukin-6 (IL-6) activities were markedly improved compared to the corresponding values of irradiated group. The histopathological results showed distinctive pattern of ischemic renal injury in irradiated group, while in treated- irradiated group the renal tissues showed relatively well-preserved architecture with or without focal degeneration. In conclusion, NS acts in the kidney as a potent scavenger of free radicals to prevent or ameliorates the toxic effects of gamma irradiation as shown in the biochemical and histopathological study and also NS oil might provide substantial protection against radiation-induced inflammatory damages.

In addition, histological examination of kidney tissue showed different disorders in normal and treated groups.

  2. Physiological and biochemical studies on the effect of septilin on irradiated male albino rats

    International Nuclear Information System (INIS)

    The present study has been initiated to evaluate the radioprotective effect of septilin against whole body gamma radiation and identifying the mechanism whereby septilin extract could protect against radiation toxicity. Irradiation induced significant increase in the serum enzymes of liver ASAT, ALAT, ALP, GGT activities and total bilirubin level when rats exposed to both gamma irradiation doses while direct bilirubin level rise when rats exposed to 6 Gy gamma irradiation only. There was a significant increase in total cholesterol, triglycerides and LDL cholesterol with significant decrease in HDL cholesterol. Besides, it produced high levels of liver malondialdehyde, nitric oxide while serum nitric oxide rise when rats exposed to 6 Gy gamma irradiation only with significant decrease in total glutathione in liver and liver superoxide dismutase activity. Irradiation induced significant decrease in WBCs, RBCs, Hb, PCV, platelets count and blood indices.Septilin manifested good melioration in the radiation-induced changes in the studied parameters and histopathological changes. Hence, it could be concluded that septilin plays a beneficial radioprotective role against radiation hazard in male albino rats.

  7. Protective Role Of Fresh Pomegranate Against Oxidative Damage In Whole Body Gamma Irradiated Male Albino Rats

    International Nuclear Information System (INIS)

    Twenty four male albino rats, body weight 100-130 g, were used to evaluate the protective role of fresh pomegranate fruit intake for 30 days on the damage induced by single dose of 6 Gy whole body gamma irradiation. The rats were randomly and equally divided into four groups: group (1): control, group (2): irradiated with 6 Gy, group (3): pomegranate for 30 days and group (4): pomegranate for 30 days followed by 6 Gy whole body irradiation. At the end of the experiment, all rats were sacrificed after 12 hours fasting then sera were separated for the determination of sugar, total antioxidant, lipid profile and liver and kidney functions. Results showed that gamma radiation caused significant decline (P<0.05) in serum total antioxidant, total protein, albumin, HDL-C and blood glucose with significant elevation (P<0.05) in other hepato-renal markers in addition to serum total cholesterol, triglycerides and LDL-C. These changes were significantly attenuated in irradiated animals pre-treated with whole fresh pomegranate fruit leading to the conclusion that pre-intake of pomegranate fruit had a radio- protective effect. This protection of this whole fruit may be due to the increased total antioxidant level leading to free radical scavenging

    This work was directed to study the possible radio-protective role of selenium and vitamin E on the level of serum total lipid, cholesterol, triglycerides, glutathione peroxidase, superoxide dimutase, catalase and the free T3 and T4 in serum blood against damage induced by free radicals produced by ionizing radiation. Male albino rats (120-140 gm) were subjected to 5 and 7 Gy whole body gamma irradiation, selenium (1.5 mg/kg) and vitamin E (10 mg/kg) were injected intraperitoneal y to rats daily for one week before exposure to whole body gamma irradiation (5 and 7 Gy). Blood samples were collected from rats for biochemical analysis at time intervals 3, 5 and 7 days post-irradiation. Serum levels of total lipid, cholesterol and triglycerides were assayed and the levels of glutathione peroxidase (GSH-Px), super oxide dismutase (SOD) and catalase (CAT) and also the levels of serum free T3 and free T4 concentrations were also measured using Radio-immunoassay technique (RIA). The data showed that irradiation at both dose levels of 5 and 7 Gy caused significant inhibition in the antioxidant enzymes (GSH-Px, SOD and CAT) in plasma in irradiated rats. Also, the data revealed significant elevation in total lipid, cholesterol, triglyceride and 7 levels, which was associated with significant decrease in serum level of free T4 compared to non- irradiated rats during the experimental periods (3, 5, 7 days). Selenium and vitamin E were injected intraperitoneal y in rats (1.5 mg/kg of and 10 mg/kg, respectively) daily for one week before irradiation exerted marked amelioration of the biochemical changes induced by radiation, which is more pronounced at the dose level 5 Gy

    Nicotine is a parasympathomimetic alkaloid present in tobacco which can induce hyperlipidemia and has a direct effect on neural functions. Statins, competitive inhibitors of 3-hydroxymethyl-3-glutaryl-coenzyme-A reductase, are cholesterol lowering drugs. It has some neuroprotective effects. Hence we analysed the combined effect of nicotine and statin on the learning behaviour of male albino rats. We employed Y-Maze conditional discrimination task. Rats were divided into 4 groups with six rats in each group. (1) Control, (2) Atorvastatin (10mg/kgb.wt), (3) Nicotine (0.6mg/kgb.wt) and (4) Atorvastatin (10mg/kgb.wt)+Nicotine (0.6mg/kgb.wt). After 30days of treatment rats from each group were selected for behavioural study and they were observed for 30days. At the end of the experimental period rats were sacrificed, and brain and liver were dissected out for further biochemical analysis. Nicotine treated group showed least performance in learning in comparison with control, atorvastatin and atorvastatin+nicotine treated groups. Co-administration of atorvastatin and nicotine improved learning behaviour compared to nicotine treated group. Reactive oxygen species level was significantly increased in nicotine group compared to control. The level of neurotransmitter serotonin which has a significant role in learning was found to be decreased in nicotine treated group compared to the control group. Activity of Na(+) K(+) ATPase, Ca(2+) ATPase and glutathione content was significantly reduced in nicotine treated group compared to control. The activity of acetylcholine esterase was significantly increased in the nicotine treated group. Expression studies showed significant decrease in N-methyl D-aspartate receptors and increase in mono amine oxidase-A and mono amine oxidase-B in nicotine treated group and was reversed in atorvastatin + nicotine treated group. It can be concluded that co-administration of nicotine with statin ameliorates the neural functional alterations caused by nicotine to a significant level. PMID:26409179

  10. Antioxidant activity of lycopene extracted from tomato pomace toward gamma irradiation hazards in male albino rats

    International Nuclear Information System (INIS)

    The present study aims to evaluate the anti oxidative activity of lycopene extracted from tomato pomace against hazards induced by gamma irradiation. Male Swiss albino rats were orally administered by lycopene (1.2 mg/rat/day) using suitable stomach tube 7 days before exposure to a sublethal single dose (6.5 Gy) of whole body gamma radiation. Lipid peroxides (MDA) levels in plasma, reduced glutathione (GSH) content and superoxide dismutase activity in blood were determined, as well as serum levels of alanine aminotransferase (ALT), aspartate aminotransferase (AST), alkaline phosphatase (ALP) and gamma glutamyl transferase activity (GGT) were investigated 7 and 15 days post-irradiation and/or lycopene administration. The results revealed that exposure to ionizing radiation resulted in significant elevation in plasma levels of MDA, serum ALT, AST, ALP and GGT, as well as significant reduction in GSH content and superoxide dismutase activity in blood. Administration of lycopene by using suitable stomach tube pre-irradiation has significantly ameliorated the radiation-induced disturbances in all the investigated parameters

    Full Text Available The present study investigated the effect of 14 days diet, enriched in butter, vitamin E (vit. E and green tea, on the major regulators of energy expenditure. Leptin is the product OB gene. This 16 KDa protein is produced by mature adipocytes and is secreted in plasma. Its plasma levels are strongly correlated with adipose mass in rodents as well as in humans. Leptin inhibit food intake, reduces body weight and stimulates energy expenditure. In order to evaluate the effect of diet enriched in butter, vit. E and green tea on body weight, adipose tissue weight and organs weight, serum lipids, lipoproteins content and serum leptin levels in male albino rats supplemented for 14 days on the previous diet. This study showed that high fat diet significantly increased body weight and adipose tissue weight, while vit. E and green tea enriched diet significantly lowered body weight and adipose tissue weight, kidney and spleen weights didn’t show significant changes in all the experimental groups. While liver weight decreased in diet supplemented with high fat diet. Also, the results showed that high fat diet and vit. E supplemented diet induced significant increase in total cholesterol, LDLc., triglyceride level with significant decrease in HDLc. level as compared to normal control rats. Finally green tea supplemented diet induced significant decrease in total cholesterol, LDLc., triglyceride level with insignificant increase in HDLc. level in control rats. On the other hand, high fat supplemented diet significantly increased serum leptin levels in rats compared to control group, while vit. E and green tea enriched diet significantly lowered serum leptin levels at the end of experimental period. In conclusion, improving the biological activity of leptin by diet modification may exist as a practical strategy for the treatment of obesity and related disorders and a diet rich in green tea to reduce the risk of cardiovascular disease (CVD obesity and also protect the liver against free radicals.

    Full Text Available Artificial sweeteners have been in use by food industries for a long time. Safety concerns raised about artificial sweeteners since they are widely used nowadays. The present work aims to study the possible changes in body weight, blood picture, liver functions, blood glucose and liver glycogen content as wel as histopathological changes induced in liver and urinary bladder of male albino rats after administration of two artificial sweeteners (saccharin or aspartame. Male rats were administered saccharin (50 mg/kg b.w. or aspartame (100 mg/kg b.w. daily by intragastric gavage for 14 weeks. The results revealed that both saccharin and aspartame provoked highly significant reduction in body weight gain %. Saccharin exerted highly significant reduction in haemoglobin (Hb level, haematocrit (Hct% and red blood cel s (RBCs count, while aspartame induced insignificant changes in al haematological parameters. Alanine aminotransferase (ALT and aspartate aminotransferase (AST activity levels were significantly increased with saccharin and aspartame. Alkaline phosphatase (ALP levels in serum showed slightly insignificant increase by saccharim administration, while aspartame caused a significant rise in ALP. Blood glucose level of rats given saccharin significantly dropped, while aspartame caused a significant elevation in blood glucose level. Liver glycogen content of rats given saccharin significantly increased, while aspartame caused a significant reduction in liver glycogen content. Microscopic examination of liver sections showed lymphocytic and macrophages infiltration of the portal traid in rats administered saccharin, while aspartame group showed no histopathological changes except slight hydropic degeneration of hepatocytes. Urinary bladder sections of rats administered saccharin revealed proliferation of the mucosal epithelial cel s into papil ary invaginated projections with highly vascularized connective tissue core and mononuclear inflammatory cel s infiltration, while aspartame group showed no histopahtological alterations. It could be recommended that the use of saccharin as an artificial sweetener should be restricted, while aspartame should not be administered to diabetic. When it is necessary to use artificial sweeteners, fresh fruits and vegetables should be ingested as they act as scavengers for the liberated free radicals and help to delay the postprandial rise in blood glucose level.

    Full Text Available The present study was undertaken to investigate the potential of green and black teas to modulate restraint stress-induced oxidative changes in male Wistar albino rats. Repeated immobilization for 4 h daily for five consecutive days per week (for 2 and 4 weeks was used as a test model. Repeated immobilization stress significantly decreased glutathione (GSH, RNA and total protein levels, while malondialdehyde (MDA levels were elevated in brain and liver tissues. Daily drinking of green or black tea only attenuated the RNA decrease and the MDA increase in stressed groups in liver tissues. Green tea group attenuated the decrease in GSH and RNA and the increase in MDA induced by immobilization stress in brain tissues. However, black tea only attenuated the increase in brain MDA in stressed animals. The effect of green tea on restraint stress was higher in brain than liver. In conclusion, the present results revealed that the antioxidative effect of green tea during immobilization stress was higher, possibly attributed to the presence of relatively higher concentrations of flavonoids than in black tea.

  17. Protective Role of Mint oil (MO) Against Radiation-Induced Oxidative Stress in Male Albino Rats

    International Nuclear Information System (INIS)

    The whole body exposure to high doses of gamma radiation resulted in alterations in the biological functions of vital organs in the body. This study is divided in two main parts: Part I - A preliminary study designed to determine the optimal dose of mint oil (MO) which delayed the onset of mortality and reduced the symptoms of radiation sickness when compared with the irradiated group. Male albino rats were assorted into two main groups. 1-Animals of this group were exposed to whole body (8 Gy) gamma irradiation. 2-Animals of this group were subdivided into 4 subgroups that received four different concentrations of mint essential oil (100, 150, 200, 250 ?1/animal/ day) for three consecutive days before irradiation. All animals were observed during 30 days for signs of radiation sickness, body weight change and mortality. The results revealed that pretreatment of rats with different doses of the MO prior to exposure to 8 Gy of gamma radiation resulted in a dose-dependent elevation in the survival time up to 200 ?1/kg b. wt., where the highest number of survival (80%) was observed 30 days post irradiation, when compared with the 8 Gy irradiated control (33.5%). The optimum protection against irradiation was observed at a dose 200 ?1/kg b. wt. and was used for the further investigations. The 2nd part intended to investigate the radio-protective effects of MO on some biochemical and haematological parameters. For this purpose, Swiss albino rats were selected and assorted into 4 groups. Animals in Group I control: animals without any treatment. Group II mint oil (MO): rats were administered orally MO once daily at a dose of 200 ?1for 3 consecutive days. Group III, Irradiated (IRR): animals were exposed to a single dose of 6 Gy gamma radiations. Group IV Rats were treated with MO (as in Group-II), and exposed to 6 Gy after half an hour of the last administration of MO. Animals of each group were sacrificed 1, 7 and 28 days post-irradiation for biochemical estimation in blood , liver, kidney and testis. Radiation exposure resulted in a significant decline in haemoglobin, hematocrite values, and erythrocytes and leucocytes counts. Significant decreases in serum EPO level, GSH content and ALP was observed in all specimens. Meanwhile, the values of MDA, serum acid phosphatase were significantly higher in irradiated rats as compared to control group. In MO pretreated irradiated animals, a significant increase was observed in blood constituents, EPO (erythropoietin) level, GSH content and ALP level in testes, liver and blood accompanied with remarkable decrease in the values of MDA, serum acid phosphatase. The results show that MO could exert a radioprotective effect by antioxidant activity, and might stimulate cellular regeneration, that may be attributed to the synergistic effects of its constituents.

    Full Text Available The protective effects of N-Acetylcysteine (NAC against orally administered titanium dioxide nanoparticles (TiO2 for 3 months on male albino rats were examined. Adult male albino rats were given saline as a control group, TiO2 (1200 mg kg-1 BW, NAC (100 mg kg-1 BW and co-treatment of NAC and TiO2 as a protective group for 3 months. Blood was assayed for serum changes in GPT, GOT, lipid profiles, cytokines and immunoglobulins profiles. Moreover, spleen was examined for alterations in cytokines expression and histopathology. Administration of TiO2 significantly increased serum levels of GPT, GOT and increased lipid profiles. Administration of NAC to TiO2 rats improved significant changes induced by TiO2 alone. There were an increase in IL-1β and IL-6 secretion in TiO2 administered rats which is normalized by NAC administration. TiO2 administration down regulated IL-8 and IL-10 secretion, while co-administration of rats by NAC together with TiO2 normalized that down regulation. Moreover, TiO2 induced toxicity in spleen that accompanied by a decrease in IgA, IgG and IgM that are normalized by NAC administration. Finally, TiO2 up-regulated IL-1β, IL-6 and TNF-β expression in spleen and NAC administration together with TiO2 normalized cytokines expression. In conclusion, present findings confirmed the protective effect of NAC on TiO2 induced alteration in immune responses in male albino rats.

  19. Role of Vitamin C As A Potent Antioxidant in Acute Radiation Induced Liver Disease (RILD) Among Male Albino Rats

    International Nuclear Information System (INIS)

    Recent studies demonstrated the role of vitamin C as antioxidant in alleviating organ damage caused by gamma irradiation. The present study was conducted to find out the effect of vitamin C on liver biochemical functions such as serum ALT, AST, albumin and bilirubin after experimental liver damage induced by gamma irradiation. Rats irradiated with gamma radiation were used as a model of liver injury terminating with necro inflammatory activity and acute hepatitis. Forty male albino rats were classified into 6 groups (G0-G5). G0 included 8 male albino rats that were divided to 2 subgroups (4 rats/subgroup). Both subgroups were exposed to gamma irradiation with 6 Gy as a single dose. The first subgroup was left for 3 weeks then serum and liver samples were collected while in the second subgroup, 2 rats were died and the remaining 2 rats were left for 6 weeks then serum and liver samples were collected. G1 was the negative control while in the rest groups, the whole body of rats was exposed to gamma irradiation of dose 8 Gy divided to 2 doses (4 Gy/one dose) at one week interval in between. G2 included 12 albino rats divided into 3 subgroups (4 rats/subgroup). The whole body of albino rats of G2 was exposed to 8 Gy gamma irradiation that divided as mentioned before. Serum and liver samples were collected after one day, two days and four days after last dose of irradiation. G3 also included 8 rats that were divided into 2 subgroups (4 rats/subgroup) and whole body was exposed to 8 Gy gamma irradiation that were divided as mentioned before. Serum and liver samples were collected after one week for one subgroup and 2 weeks for other subgroup after last dose of irradiation. The rest 2 groups (4 rats/group) were exposed to 8Gy gamma irradiation divided as before, but the rats in one group were orally supplemented with low dose of vitamin C. G4 and the others were supplemented with high dose of vitamin C for 2 weeks starting after last dose of irradiation (G5) then serum and liver samples were collected. Liver biochemical functions and histopathological examinations were done. The data of the current study showed mild non-significant alteration in the levels of liver biochemical parameters towards the level of baseline particularly when albino rats exposed to 6 Gy gamma irradiation as a single dose and left for 3 or 6 weeks for recovery. Exposure to accumulative dose of 8 Gy gamma irradiation caused worse alteration in both biochemical markers associated with obvious damage in hepatocytes causing acute liver injury in histopathological examination especially after 4 days of gamma radiation exposure but when albino rats were orally supplemented with vitamin C, there were significant amelioration and marked regression towards normal position in both biochemical parameters and histopathological pictures, so, the present data revealed that oral dose of vitamin C has trends to support the liver during the acute phase post-gamma irradiation and enhance its spontaneous recovery

  20. The role of melatonin in radiation induced biochemical disturbances in brain and thyroid gland in adult male albino rats

    International Nuclear Information System (INIS)

    Radiation induced changes in adult male albino male rats before and after melatonin administration were monitored to detect some biochemical changes in brain and thyroid gland. The parameters monitored were dopamine (DA), norepinephdne (NE) and gamma aminobutyric acid (GABA) in brain and triiodothyronine (T3) thyroxine (T4) and thyroid stimulating hormone (TSH) in serum of irradiated adult male albino rats before and after intraperitoneal injection of melatonin. Results indicated that 6.0 Gy whole body ?-irradiated rats showed gradual and significant decrease in DA, NE and GABA contents in different brain areas under investigation (cerebellum, pons+medulla oblongata, corpus striatum, cerebral cortex, hypothalamus, midbrain and hippocampus). The maximum effect of whole body ?-irradiation was observed after 21 days. Moreover, gradual and significant decrease in serum T3 and T4 levels were recorded after ?-irradiation. However, TSH level showed significant elevation throughout the experimental period. Melatonin at a dose level of 15 mg/kg b.wt. was intraperitoneally injected daily 30 minutes after 6.0 Gy whole body ?-irradiation, ameliorated DA, NE and GABA contents in different brain areas compared to those measured in irradiated rats. Moreover, melatonin gradually attenuated the effect of ?-irradiation on serum T3 and T4 levels to reach nearly the control level at day 21 after melatonin injection. However, melatonin ameliorated the elevated TSH level induced by ?-irradiation to reach its corresponding control value at day 21

    Alopecia is a dermatological disorder with psychosocial implications on patients with hair loss. Eclipta alba Hassk. is a well-known Ayurvedic herb with purported claims of hair growth promotion. In the reported work attempts were undertaken to evaluate petroleum ether and ethanol extract of E. alba Hassk. for their effect on promoting hair growth in albino rats. The extracts were incorporated into oleaginous cream (water in oil cream base) and applied topically on shaved denuded skin of albino rats. The time (in days) required for hair growth initiation as well as completion of hair growth cycle was recorded. Minoxidil 2% solution was applied topically and served as positive control for comparison. Hair growth initiation time was significantly reduced to half on treatment with the extracts, as compared to control animals. The time required for complete hair growth was also significantly reduced. Quantitative analysis of hair growth after treatment with petroleum ether extract (5%) exhibited greater number of hair follicles in anagenic phase (69 +/- 4) which were higher as compared to control (47 +/- 13). The result of treatment with 2 and 5% petroleum ether extracts were better than the positive control minoxidil 2% treatment. PMID:18478241

    Full Text Available Anti-fertility effect of ethanol extract of whole plant extract of Sarcostemma secamone was observed in male albino rats. The relative weight of the testes and epididymis were decreased. The epididymal sperm count, motility and sperm abnormality were reduced significantly in treated rats. There was an increase in serum protein, albumin, globulin, urea, creatinine and the activity of liver marker enzymes (SGOT, SGPT and ALP levels of control and treated rats. The activities of serum antioxidants (CAT, SOD, GPx, GST and GRD in plant extract treated rats were decreased. The results of the hormonal assay showed that increased serum levels of FSH and estrogen but decreased in the serum levels of LH and testosterone compared to control. The results of fertility test indicated that the treated adult male rats reduced the number of female’s impregnation. In addition, the number of implantations and the number of viable featuses were also decreased. The results of the present study concluded that, ethanol extract of whole plant of Sarcostemma secamone inhibited sperm concentration, motility and testosterone which might result in a male fertility.

  5. Protective effect of L-methionine on blood reduced glutathione, glucose-6-phosphate dehydrogenase and some haematological parameters in gamma-irradiated albino male rats

    International Nuclear Information System (INIS)

    Gamma-irradiation of the whole body of male albino rats at single dose levels (100, 300 and 600 rad) significantly decreased blood reduced, glutathione (GSH), glucose-6-phosphate dehydrogenase (G-6-P D H). activity, glutathione stability, red blood cell (R B C s) count, hemoglobin (Hb) content and packed cell volume % (P C V %). The reduction in the above cited criteria was dose and time dependent.

    Full Text Available Abhrak bhasma, an Ayurvedic drug used against many diseases including hepatitis. In present study various doses of abhrak bhasma (10, 20, 30 and 40 mg/kg body wt were tested for hepatoprotective efficacy against carbon tetrachloride (CCl4 intoxicated liver and kidney functions in male albino rat. Administration of CCl4 to the normal rat increased serum levels of AST, ALT, ALP and bilirubin indicated acute damage. Abhrak bhasma treatment counteracted the action of CCl4 on liver and kidney functions. With the administration of increasing doses of abhrak bhasma all activities were dropped progressively and significantly at 40 mg dose as compared with silicate control. Conjugation metabolism and excretion of bilirubin were improved with increasing doses of abhrak bhasma suggesting dose dependent protection of all metabolic steps in bilirubin metabolism. Also CCl4 induced acute toxicity increased serum urea and creatinine content, which was progressively controlled by increasing abhrak bhasma doses. The findings of this study indicated that abhrak bhasma exert dose dependent protective effects in liver and kidneys functions against CCl4 induced toxicity in albino rat.

    The present study aims to investigate the synergistic effects of squalene and omega-3 as an antioxidant in protection against oxidative stress which induced by gamma- irradiated in male albino rats. The experimental animals, male albino rats (n=48) weighing (120-150 g) were divided into 4 groups: control, gamma irradiated with a single dose of 6 Gy, oral administration with 0.4 ml/kg b. wt from squalene and omega-3 for 30 days and oral administration with 0.4 ml/kg b. wt from squalene and omega-3 for 30 days and irradiated with a single dose level (6 Gy). Animals were sacrificed on the 3rd and 7th day post irradiation. Biochemical analysis was carried out on blood glutathione content (GSH), superoxide dismutase activity (SOD), catalase activity (CAT) and lipid peroxidation (MDA). Also lipid profile: plasma total cholesterol (TC), triglycerides (TG), LDL-cholesterol (LDL-C) and HDL-cholesterol (HDL-C) were assayed. Exposure to gamma radiation at dose level 6 Gy elevated significantly lipid peroxidation (MDA) and decline in level of blood glutathione content (GSH), superoxide dismutase activity (SOD), and catalase activity (CAT) also, a significant increase in plasma total cholesterol (TC), triglycerides (TG), LDL-cholesterol (LDL-C) and decrease in HDL-cholesterol (HDL-C). Combined supplementation of squalene and omega-3 significantly prevented the elevation of (MDA) and decline in antioxidant parameters after radiation and ameliorates plasma lipid profile. The results indicated that the combination of aqualene and omega-3 has a protective role, antioxidant effect and antilipidemic effect against gamma radiation in exposed rats

  9. Antioxidant Activity of Cabbage and/or Carrot Against Oxidative Stress Induced by Gamma Irradiation in Male Albino Rats

    International Nuclear Information System (INIS)

    Several studies indicated that diets rich in fruits and vegetables are protective against diseases, and populations that consume such diets have higher plasma antioxidants and exhibit lower risk of cancer and cardiovascular diseases. Vegetable is considered major dietary source of fibers and antioxidants such as polyphenols, flavonoids and carotenoids that can protect against different dietary disorders. The present study was carried out to investigate the potential protective effects of cabbage and/or carrot against oxidative stress induced by gamma irradiation in male albino rats. Chemical composition and phenolic contents in cabbage and carrot were determined. Male albino rats were exposed to 5 Gy (single dose with rate 0.46 Gy/min) of whole body gamma irradiation. Thirty five rats were randomly divided into five groups as follow: group 1: control (rats fed on balanced diet for 6 weeks), group 2: irradiated (rats were exposed to whole gamma irradiation and fed on balanced diet for 6 weeks) and groups 3, 4 and 5: irradiated rats fed on balanced diet and received cabbage 15%, carrot 15% and a combination of cabbage and carrot, respectively. The results obtained revealed that the administration of cabbage and/or carrot diet significantly reduced the changes induced by gamma irradiation in the serum level of glucose and liver function parameters; serum aminotransferases (AST, ALT), alkaline phosphatase (ALP), total protein and albumin. In addition, significant improvements were observed in the serum levels of total cholesterol (TC), triglycerides (TG), low density lipoprotein-cholesterol (LDL-C) and high density lipoprotein-cholesterol (HDL-C). Significant enhancement in hepatic antioxidant enzymes; superoxide dismutase (SOD) and catalase (CAT), was observed. The levels of reduced glutathione (GSH) associated with remarkable decrease in the level of lipid peroxidation (TBARS) were observed. Accordingly, it could be concluded that consumption of cabbage and/or carrot could modulate the oxidative stress and protect against chronic diseases caused by radiation exposure and that may be due to the antioxidant activity of both cabbage and carrot

    L-carnitine, a natural component of mammalian tissue, is a necessary factor in the utilization of long-chain fatty acids to produce energy. Furthermore it has been shown to protect cells from per oxidative stress. The objective of the present study was to evaluate the efficacy of L-carnitine on hepatotoxicity and nephrotoxicity induced by paracetamol, ?-radiation, and paracetamol + ?-radiation. Male albino rats were divided into 8 groups. 1-Control group: rats not subject to any treatment, 2-Carnitine group: rats received L-carnitine (0.5 ml/Kg body weight) via intraperitoneal injection during 21 days, 3-Paracetamol group: rats received paracetamol (50 mg/kg body) via intraperi-toneal injection during 21 days, 4- Carnitine + Paracetamol group: rats received L-carnitine in parallel to paracetamol treatment, 5- Radiation groups: rats were whole body gamma irradiated with 7 Gy, 6- Carnitine + Radiation group: rats received L-carnitine for 21 days before whole body gamma irradiation with 7Gy, 7- Paracetamol + Radiation group: rats received paracetamol during 21 days before whole body gamma irradiation, 8- Carnitine + Paracetamol + Radiation group: rats received L-carnitine parallel to paracetamol during 21 days before whole body gamma irradiation.The results demonstrated that rats receiving paracetamol, as well as whole body gamma irradiated rats and rats receiving paracetamol and irradiated showed a significant increase of alanine amino transferase (ALT), aspartate amino transferase (AST), and alkaline phosphatase (ALP) activities, and a significant decrease of gamma-glutamyl transpeptidase (GGT) activity indicating liver injury. A significant increase of urea, creatinine and uric acid levels was recorded also indicating kidney damage. Alteration in liver and kidney functions was accompanied by a significant increase in the content of thiobarbituric acid reactive substances (TBARS) associated with a significant decrease in glutathione (GSH) content and superoxide dismutase (SOD), and catalase (CAT) activities indicating oxidative stress. The administration of L-carnitine resulted in significant improvement of hepatic and renal function tests associated with the reduction of oxidative stress. It could be concluded that L-carnitine might modulate paracetamol and ?-radiation induced hepatotoxicity and nephrotoxicity possibly through its antioxidant properties

    International Nuclear Information System (INIS)

    This study deals with the preparation and microbiology of the mycotoxin ochratoxin A (OA) that was extracted from Aspergillus niger and injected intraperitoneally to male albino rats at a single dose of 2.5 mg/kg body weight (1/5 LD50). Its effect was followed after 6, 24, 48, 72, 96 hours and 7 days. Body weight gain, organs body weights ratio and some hematological and biochemical parameters were investigated. The results revealed significant decrease in body weight gain of treated rats in addition to an alteration in the relative weights of some selected organs. The data revealed dramatic decrease in RBCs count, hemoglobin level, hematocrit value and platelets number, where WBCs count was significantly increased. Moreover, significant increases of serum ALT, AST, ALP and total and direct bilirubin were observed indicating changes in liver function. Total protein and albumin were significantly decreased. Kidney function of treated rats, as determined by alterations in creatinine and blood urea levels, was affected. Also, profound decline in serum testosterone level was observed as performed by radioimmunoassay technique

    Full Text Available Background: Generation of free radicals in the renal cortex plays an important role in the pathogenesis of gentamicin-induced nephrotoxicity. Curcumin, the yellow curry pigment isolated from turmeric, has been confirmed to have a strong antioxidant and free radical scavenging actions. In the present study, we investigated the possible protective effect of curcumin against gentamicin-induced nephropathy in male albino rats. Methods: Thirty two male albino rats were divided into 4 equal groups (Gr.: (Gr.I control, injected i.p with 1cc isotonic saline solution/day for 8 wks; (Gr.II received 200 mg/kg/day curcumin (Cur. orally, suspended in normal saline, for 8 wks ; (Gr.III injected I.p by 100 mg/kg/day gentamicin (Gen. for 8 days followed by 1cc saline I.p thereafter; (Gr.IV (Cur./Gen. received 200 mg/kg/day Cur. for one week before starting Gen injection (100 mg/kg/day for 8 days during which Cur. was received concurrently with Gen then Cur administration was continued thereafter throughout the rest of the study (6 wks. Body weight was recorded weekly. Renal function was evaluated by measuring the 24 h. urine output, the concentrations of plasma creatinine, blood urea nitrogen (BUN and creatinine clearance. Also, kidney weight and the parameters of oxidative stress: reduced glutathione (GSH, thiobarbituric acid reacting substance (TBARS and the activities of superoxide dismutase (SOD, catalase and glutathione peroxidase (GPX were measured in kidney tissue. Results: The Kidney weight, plasma creatinine, BUN and 24 h urine output were significantly increased while the body weight and creatinine clearance were significantly decreased (P < 0.0005, in rats treated with Gen. as compared to control. While Cur. could significantly normalize the previous parameters. In addition Gen. caused oxidative stress in kidney as seen by significant increase in TBARS level, and significant decrease of catalase, GSH, SOD and GPX activities (P < 0.0005, However, Cur. could normalize all the above parameters as compared to control. Conclusion: Our data indicate that Cur. could suppress renal toxicity by blocking oxidative injury in the kidney and restore the antioxidant enzymatic profile. The renoprotective effect of Cur. is also evident by a remarkable improvement of renal function in Gen. injected rats. So Cur. can be used as a potent protective agent against renal oxidative damage mediated by Gen.

CCl4 caused an elevation of serum triglycerides with no effect on serum total cholesterol. it also increased serum creatinine and urea levels . these biochemical results were in coincidence with the liver and kidneys histopathological alterations . using radioimmunoassay, it was found that serum total testosterone level was significantly decreased while that of serum dehydroepiandrosterone sulphate (DHEA-S) was significantly increased due to CCl4 treatment

  15. Sweet potato Ipomoea Batatas Modulates Radiation-induced Oxidative damage in Liver and kidney of Male Albino Rats

    International Nuclear Information System (INIS)

    Sweet potato Ipomoea Batatas, one of the major vegetable crops consumed worldwide, is rich in phytochemicals, which displayed antioxidant activities. This work aims at assessing the radio-protective properties of sweet potato tubers on liver and kidney tissues. Male albino rats were whole body exposed to 0.5 Gy day after day for a period of 20 days. Animal received orally prepared aqueous extract of sweet potato tubers (100 mg kg/body weight), one week before irradiation and during the period of radiation exposure. The results demonstrated that irradiation of rats induced a significant increase in lipid peroxides level measured as thiobarbituric acid reactive substances (TBARS) concomitant with a significant decrease in superoxide dismutase (SOD), and catalase (CAT) activity and glutathione (GSH) content in liver and kidney tissues. Administration of a freshly prepared aqueous extract of sweet potato tubers to rats, one week pre-irradiation and during the period of radiation exposure has significantly of ameliorated the oxidative stress in both tissues. The significant amelioration in oxidative stress was substantiated by improvement of liver and kidney enzymes Treatment of rats with sweet potato has significantly reduced the increase in serum alanine amino transferase (ALT), aspartate amino transferase (AST) and lactate dehydrogenase (LDH) activity, serum creatinine and urea levels. Furthermore, hyperglycemia and alteration in lipid profile manifested by a significant increase in triglycerides (TG), total cholesterol (TC), and low density lipoprotein cholesterol (LDL-C), and a significant decrease in high density lipoprotein cholesterol (HDL-C), were improved in sweet potato-treated irradiated rats compared to those only irradiated. According to the results obtained in the present study, it could be concluded that sweet potato through its antioxidant activities could protect cellular membrane from radiation induced oxidative damage in animals and preserve the integrity of tissue functions.

  16. The Protective Efficacy Of Extract Of Hibiscus Sabdariffa (Karkade) Calyces Against Alcohol Toxicity In Male Albino Rats

    International Nuclear Information System (INIS)

    Hibiscus sabdariffa (HS), Malvacea family, is a medicinal plant with a worldwide fame. Its benefit effect on some physiological parameters as blood picture, blood pressure, fasting blood sugar, lipid profile, liver and kidney functions, electrolytes and antioxidant capacity is mentioned in several recent studies. The purpose of this study was to assess the efficacy of this plant in protecting from alcohol toxicity in rats. Thirty two adult male albino rats were divided into four equal groups: group 1 received water orally for 30 days, group 2 received ethanol (5 ml/kg/day) for 30 days, both group 3 and group 4 received Hibiscus sabdariffa (100 mg/kg/day) orally for 30 days and then group 4 received ethanol (5 ml/kg/day) orally for another 30 days. Serum hepatic markers (aspartate and alanine minotransferases; AST and ALT), alkaline phosphatase (ALP) and gamma glutamyl transferase (GGT) were increased significantly by alcohol abuse with no observed improvement in treatment with HS. Significant reduction in total protein and albumin was observed in alcohol abuse which improved with HS treatment and showed significant increase as compared with both control and alcohol treated groups. Serum kidney markers (urea, creatinine and uric acid) were increased in alcohol abuse and only creatinine and uric acid nearly returned to normal levels with HS treatment while urea level remains high. Serum glucose was increased significantly in alcohol abuse and significantly decreased in group 3 (HS treated) and group 4 (HS + ethanol). Serum total cholesterol, triglycerides, high density lipoprotein-cholesterol (HDL-C), low density lipoprotein-cholesterol (LDL-C) and atherogenic index were increased significantly while HDL-C was significantly reduced in alcohol abuse. HS treatment resulted in significant increase in HDL-C and therefore decreased atherogenic index in both group 3 and group 4 which indicated protective effect of HS for coronary heart diseases. These results lead to the conclusion that the use of HS against alcohol toxicity in male albino rats caused partial protection for different body systems.

  17. Role of carnitine in ameliorating the lead and / or irradiation induced toxicity in male albino rats

    International Nuclear Information System (INIS)

    This work: aimed to investigate the protective effect of carnitine (3-hydroxy-4-N-trimethyl amino butyric acid) on the contents of total protein, albumin, glucose and lipid peroxides as malonaldehyde (MDA) in serum, in addition to liver glycogen and lipid peroxides content 1, 2, 4 weeks after exposure of rats to a collective dose of 4 Gy whole body gamma irradiation and / or lead treatment. Adult male rats received lead (50 mg/kg body weight) and / or exposed to fractionated dose (4 Gy) of gamma irradiation delivered as 0.5 Gy twice weekly for four weeks. Results of the present study revealed that fractionated whole body gamma irradiation and / or lead administration induced cellular damage manifested by a significant decrease in serum total protein and albumin, and a significant increase in serum glucose and MDA content as well as significant increase in liver glycogen and MDA. Administration of carnitine (200 mg/kg b.wt.) before lead and / or gamma irradiation, has significantly ameliorated the observed changes, indicating the prophylactic action of carnitine on lead and / or irradiation toxicity

  18. The ameliorative effect of grape seed extract(GSE) on sodium borate-inducing kidney injury of male albino rats

    International Nuclear Information System (INIS)

    Borax (sod-borate) is a toxic compound that is implicated daily to environmental pollutant, so occupational exposure leading to adverse effects on functions of some organs causing their damage as nephrotoxicity, neurotoxicity, hepatotoxicity and testicular atrophy . In particularly, kidney is the most organ that is affected by borax exposure due to continuous exposure with slow rate of excretion leading to accumulation in the renal tissue. Supplementation with high potent antioxidant grape seed extract may alleviate the worse damage effects induced in the kidney as a result of continual exposure of borax in our daily life. The current study aimed to evaluate the ameliorative effect of grape seed extract on renal injury of male albino rats intoxicated with sod-borate. Twenty eight male albino rats were classified to 4 groups(GI and II and III and IV).GI served as a control, group GII was a group intoxicated with sod-borate for 45 days, where as rats in GIII supplemented with GSE beside sod-borate for 45 days , GIV was a group supplemented with GSE only. Serum and kidney samples were collected for biochemical, histopathological and DNA examinations. Significant elevation in the levels of blood urea and creatinine in GII were observed when compared to control group(GI). Significant decline were prominent in biochemical kidney functions when intoxicated group supplemented with GSE(GIII) , where as non significant changes were observed between control group and group supplemented with GSE only (GIV). Significant increase in both cytokines TNF-? and IL-6 was observed in group intoxicated with sod-borate(GII) when compared to control rats(GI). Oral supplementation with high potent antioxidant GSE (GIII) caused alleviation in the kidney injury leading to the reduction of both pro-inflammatory mediator cytokines TNF-? and IL-6. DNA% fragment migration showed that worse significant migration of DNA fragements were observed in toxicated group(GII) followed by increase in tail length that was evaluated by a fluorescence microscope, but supplementation with GSE(GIII) caused significant improvement with reduction in the percentage of DNA fragements migration contributing to renal tissue recovery. Corticosteroid levels were elevated in intoxicated group(GII) when compared to control group(GI), whereas significant reduction in the level of corticosteroid were observed when intoxicated rats were supplemented with GSE(GIII). Histopathological examination showed that orally administration with sod-borate induced worse alteration with sever damage in renal tissue when compared to control. Supplementation with GSE to intoxicated group resulted in improvement in the damaged renal tissue with mild congestion when compared to intoxicated group . No histological structure alteration were observed between control group and supplemented group with GSE only. The present work concluded that GSE may act as a natural therapeutic agent to alleviate and neutralize the nephrotoxicity and oxidative stress induced by Sod-borate

  19. Serotonin exerting protection of serum lipid pattern in male albino rat subjected to shot or intermittent whole body gamma irradiation

    International Nuclear Information System (INIS)

    Certain cancer patients are subjected to varying levels of intermittent radiation delivered in certain cases as whole body exposure. Effective control of many haematological complications built up during radiation treatment would necessarily contribute to up-grading of cancer radiotherapy. In the present study, the effect of either shot or intermittent whole body gamma irradiation at cumulative dose levels up to 6 and 10 Gy, have been evaluated on the levels of total lipids and lipid fractions in blood serum of male albino rats. The pharmacological role of serotonin and its potential radioprotective capacity have been assessed on the serum lipid pattern. The results indicated generally significant increases in the levels of blood lipid fractions especially HDL-cholesterol. On the other hand, the level of LDL-cholesterol recorded a significant decrease on the third day post either shot or cumulative dose levels at 6 or 10 Gy and also post 4 successive doses of serotonin administration. The only exceptions were recorded in the case of LDL-cholesterol post administration of single dose of serotonin and serotonin prior to shot dose levels of 6 or 10 Gy. 2 tabs

  20. Cinnamon (Cinnamomum zeylanicum N) attenuates hepatic and cardiac tissues injury induced by gamma radiation in male albino rats

    International Nuclear Information System (INIS)

    The purpose of this study was to investigate the protective role of cinnamon; a spice rich in eugenol, cinnamic acid and cinnamic aldehyde, against tissue injuries induced by gamma irradiation. Moreover, the effect of time of cinnamon aqueous extact (aq.extr).administration was evaluated. Cinnamon aq.extr. (200 mg/Kg body weight) was administered to male albino rats via gavages during 15 successive days or 40 successive days before whole body exposure to gamma rays (3Gy). The animals were sacrificed the 3rd day post-irradiation. The results obtained revealed that the administration of cinnamon aq.extr. during 15 successive days or 40 successive days before irradiation has significantly attenuated hepatic and cardiac tissue injuries. Necrosis, apoptosis, cell death and rupture of cell membrane in both tissues were less severe. However, the protection was better when cinnamon aq.extr.was administered for 40 successive days before irradiation. It could be concluded that taking adequate amount of cinnamon aq.extr. for a long time would protect hepatic and cardiac tissues from radiation-induced damage

    Full Text Available Emotional changes can influence feeding behavior. Feed intake is the cornerstone of animal productivity. The consequences of inadequate intake include inhibited growth, delayed puberty, infertility, reduced milk production and lowered resistance to parasites and disease. In this study, the histological changes observed in male albino rats’ stomach mucosa which was exposed to hunger were examined. Pieces from stomach were taken in the 1st-5th days following last feeding. These tissue specimens were fixed by using 10% neutral formalin which was compressed. After routine tissue checks, the tissue pieces were sunk into paraffin wax and some blocks were prepared. With the aim to examine histological structures of the pieces taken, they were stained with Hematoxylin and Eosin (H and E. An increase in the number of blood cells taken part in stomach tissue was observed in the first 24 h. At the end of the 3rd day of hunger, necrosis of fundic glands, especially the base of fundus and mild congestion of mucosal blood vessels were observed. A widening in glandular epithelium lumen was seen after 2 days. A tendency to slim was observed in mucosa layer of the surface and glandular lumen during hunger. In the stomach mucosa, structural changes were caused by hunger. It was found that these changes were in direct proportion with hunger duration.

  2. Efficiency of hesperidin, natural citrus bioflavonoids, as antioxidant against gamma irradiation hazards in male albino rats

    International Nuclear Information System (INIS)

    Nowadays, increasing attention has been given to the roles of free radicals generated through the oxidative stress. The present study aims to evaluate the anti oxidative role of hesperidin (C28H34O15), natural citrus bioflavonoids, against hazards induced by gamma irradiation. Male rats were administered hesperidin (25 mg/kg body weight) by a suitable stomach tube two weeks before exposure to whole body fractionated dose of gamma radiation (2 Gy day after day for three times intervals). Levels of lipid peroxides (MDA), sodium (Na), potassium (K), total cholesterol, triacylglycerol, high density lipoprotein (HDL-C), low density lipoprotein (LDL-C) were investigated in serum 1, 7 and 15 days post-irradiation and / or hesperidin administration. The results revealed that exposure to ionizing radiation resulted in significant elevation in MDA, K, cholesterol, triacylglycerol and LDL-C, 1, 7 and 15 days post the last dose of radiation exposure. Meanwhile, radiation exposure caused significant reduction in Na and HDL-C. Orally administration of hesperidin by suitable stomach tube pre-irradiation has significantly ameliorated the radiation induced disturbances in all the investigated parameters. It could be concluded that administration of hesperidin may have a beneficial role in modulating oxidative stress by improving the natural antioxidant mechanism

  4. Amelioration of some biochemical parameters in irradiated male albino rats by garlic

    International Nuclear Information System (INIS)

    Garlic extract has various medical effects on the treatment of many diseases as hypertension, atherosclerosis, inflammation and diabetes. The alteration of the biochemical parameters in blood serum of irradiated rats may play an important role in determining the pathogenesis of radiation exposure. Many of the damaging effects of ionizing radiation are mediated by reactive free radicals. This study was designed to evaluate the protective role of garlic against gamma irradiation (5Gy) induced biochemical disorders in rats. Samples were collected at 1, 7 and 14 days post-irradiation. Lipid peroxide content (malondialdehyde), cholesterol, HDL-C, LDL-C, fatty acids, glucose, insulin, glycogen, haemoglobin, ferritin andiron were estimated.Garlic was orally administered to rats (100 mg/kg body weight) for 14 days before exposure to single dose of gamma irradiation at dose level 5 Gy. The data revealed significant increase in the levels of lipid peroxide, cholesterol, LDL-cholesterol, fatty acids, insulin, glucose and iron accompanied with significant decrease in the levels of HDL-cholesterol, glycogen, haemoglobin and ferritin due to radiation exposure. Administration of garlic alone to the rats caused nonsignificant changes in the estimated parameters indicating its safe use, but the treatment with garlic to rats before radiation exposure ameliorated the changes induced by gamma irradiation and tended to normalize their levels.It could be concluded that garlic administration may has a beneficial role in restoring the biochemical disorders induced by 5 Gy gamma irradiation

    The study determined the maximum intraperitoneal (ip) scopolamine dose inducing memory impairment in rats (2 mg/kg) compared to 0.5 or 1 mg/kg dose. The effect reflected by significant increase from normal in the latency time required for rats to find the hidden platform in water maze task and acetylcholinesterase (AChE) activities in cortex, hippocampus and striatum. The dose-related histopathological effect via the hemorrhage, vacuolation and gliosis in cortex and hippocampus is assessed. Then the study investigated the potency of Panax ginseng root extract on scopolamine cognitive dysfunction rat model compared to memantine hydrochloride as reference Food and Drug Administration approved. Ginseng extract was administered at dose 100 or 200 mg/kg/day and memantine at 20 mg/kg/day orally for 2 weeks. All treatments showed improvement in the water maze task, however, ginseng (200 mg/kg) group acquired the advantage without statistical difference control. Scopolamine (2 mg/kg ip) group showed significant increase in AChE reactivity and glutamate level and reduced monoamines (norepinephrine, dopamine and serotonin) and ?-aminobutyric acid contents in cortex, hippocampus and striatum. Ginseng extract in a dose-dependent manner appears effective as memantine and can improve memory impairment through the retrieved homeostasis via neurotransmitter levels and AChE activities in rat brain areas with partial effect on the histological feature of the brain tissue.

  7. Effect of Carbonated Beverage Intake on Blood Gases and Some Biochemical Parameters in Male Albino Rats

    International Nuclear Information System (INIS)

    The purpose of this study was to identify the effect of carbonated beverage (colourless or black coloured drinks) on arterial blood gases, kidney function, bone mineral density (BMD), glucose and insulin. The rats were divided into three groups; ten rats per each group. Group (I) used as control, group (II) rats supplemented with colourless carbonated beverage (10 ml /100 ml water) and group (III) rats supplemented with black coloured carbonated beverage (10 ml /100 ml water) for three months. The arterial blood gases were evaluated by measuring ph PO2, , PCO2, , H+ a nd HCO3-. Rats receiving the coloured drinks showed high significant increase in ph while PO2 showed very high significant decrease in both groups. PCO2 showed high significant decrease in groups (II) and (III) while H+ showed high significant decrease in group (III) only. HCO3- showed high significant increase in group III. All these changes were related to carbonic acid dissolved in water and the increased ph lead to alkalinity of the blood and it is inversely proportional to the number of hydrogen ions (H+). Non-significant changes were observed in sodium ions while potassium ions showed significant increase in group (II) and high significant increase in group (III). The level of urea showed high and very high significant increase in groups (II) and (III), respectively. Creatinine level showed non-significant increase in group (III). The histopathology changes were observed in kidney tissues in rats of groups (II) and (III). From these results, it appears that black coloured beverage can increase the risk of kidney problems more than colourless beverages. Ca+ and inorganic phosphorous levels showed non- significant change except Ca ions showed a significant decrease in rats of group (III). The acidity of carbonated beverage leads to weak bones by promoting the loss of calcium. The decrease of bone mineral density was more pronounced in some parts of femur of rats receiving black colour carbonated beverage than rats receiving colourless carbonated beverage. The black colour beverages have caffeine which may be the reason for decreasing bone mineral density. Very high significant increase was recorded in glucose level in groups (II) and (III) while insulin was decreased significantly in group (II), and very high significant decrease in group (III) was observed which lead to diabetes mellitus. It could be concluded that carbonic acid found in carbonated beverages may lead to the alkalinity of the blood which reflect metabolic problem. Cola beverages can increase the risk of kidney problems more than non-cola sodas. Cola beverages consumption may have adverse effects on bone mineral density and furthermore, cola beverages consumption is a significant risk factor for devolving of metabolic syndrome such as insulin resistance that might result in diabetes

  8. Evaluation of the radioprotective Effect of the co-oral Administration of Vitamin B12 with Vitamin c on some Haematological and Biochemical Alterations in Male Albino Rats

    International Nuclear Information System (INIS)

    The objective of this study was to evaluate the prophylactic efficacy of co-oral administration of vitamin B12 with vitamin C against radiation induced haematological and biochemical alterations in male albino rats. Male albino rats were divided into six groups (n=8). Group 1: rats were kept as control, Group 2; rats received orally vita-min B12 (2000?gkg-1). Group 3; rats received Vitamin B12 with Vitamin C (500mgkg-1). Group 4; rats whole body exposed to 7Gy of gamma rays. Group 5; rats received vitamin B12 for 21 successive days before irradiation. Group 6; rats received Vitamin B12 with Vitamin C for 21 successive days before irradiation. Animals were sacrificed the third day post irradiation. The oral administration of Vitamin B12 with or with-out Vitamin C enhanced the recovery from radiation-induced haemopoietic injury and some biochemical changes demonstrated by a significant increase (p0.05>) of WBCs, RBCs and Platelets count, Hb content, Hct%, serum erythropoietin and iron levels and a significant reduction (p0.05>) of serum homocysteine level (Hcy), creatine kinase (CK-MB) and lactate dehydrogenase (LDH) activities compared to their respective values in irradiated rats. Improvement of oxidative stress in heart and spleen tissues denoted by a significant decrease in lipid peroxidation (MDA) and a significant increase in glutathione (GSH) content was recorded also. The co-oral administration of vitamin B12 with vitamin C has no effect on the prophylactic efficacy of vitamin B12

  9. Influence of Monosodium Glutamate on Radiation-Induced Biochemical Alterations in Male Albino Rats

    International Nuclear Information System (INIS)

    The consumption of foods and beverages containing additives has intensely increased over the past decades. Monosodium glutamate (MSG) is one of the main flavor enhancer that can be consumed in high concentrations. Also, human exposure to ionizing radiation (RAD) has become inevitable with its vast application in diagnosis and industry. Humans are frequently exposed to RAD and MSG from various food additives, therapeutic treatments and the environment. Although the use of additives and exposure to RAD in therapeutic treatments are believed to be relatively safe, their combined effects remain unclear. The present study proposed to investigate neurotoxic potentials of exposure to MSG and/or RAD on oxidative stress, neurotransmitters disturbance and metabolic disorders in the rat’s brain tissue. MSG was supplemented daily by gavages to rats at a dose of 450 mg/Kg bwt/day (equivalent to 5 g/day human consumption) for 7 days pre- and 21 days post-exposure to whole body gamma rays at doses of 2 Gy/week up to a total dose of 8 Gy. Exposure to MSG and/or RAD -induced oxidative stress, neurotransmitters disturbance and metabolic disorders. Oxidative stress was manifested by a significant increase in lipid peroxidation product malondialdehyde (MDA) and decrease in the activity of antioxidant enzymes, superoxide dismutase, catalase and glutathione content. The administration of MSG daily during exposure to gamma radiation has potentiated oxidative stress regarding each single treatment. MSG-exposure induced a highly significant decrease of serotonin (P<0.01) and a slight non significant increase (P>0.05) of aspartic and glutamic acids levels while in RAD- group the decrease of serotonin and the increase of amino acids were very highly significant (P<0.001). MSG + RAD-exposure had potentiated the decrease of serotonin and produced an additive effect on the increase of neurotransmitters amino acids. MSG as well as RAD-exposure increased (P<0.05) glucose and insulin levels with no effect on insulin resistance and their co-administration produces an additive effect compared to each single treatment. Regarding lipid profile, MSG as well as RAD-exposure induced hyperlipidaemia more noticeable in case of irradiation. Their co-administration had potentiated hyperlipidaemia compared to each single treatment. It is concluded that exposure to MSG together with RAD increased oxidative stress and neurotransmitter alteration in the brain and the risk of metabolic syndrome. It is thus recommended to limit the intake of MSG when human are at risk of overexposure to ionizing radiation.

  10. Effect of salvia a Egyptiaca extract on serotoninergic system and cortisol in adult male albino rats

    International Nuclear Information System (INIS)

    The daily oral administrations of Salvia aegyptiaca extract with a dose of 2 g/kg body weight (0.5 ml solution /rat) for 4 weeks resulted in significant increases in tryptophan, serotonin (5-HT) and 5-hydroxyindoleacetic acid (5-HIAA) levels in all tested brain areas, almost allover the experimental period. Also, it caused significant decrease in serum cortisol level. According to the obtained results, it could be concluded that the extract of Salvia egyptiaca may affect GABA-benzodiazepine receptors, that eventually inhibit the release of adrenocorticotrophic hormone (ACTH) which consequently caused decrease in serum cortisol level. The low level of cortisol inhibits the tryptophan pyrrolase activity resulting in an increase of the peripheral availability of tryptophan for 5-HT synthesis in brain. Accordingly, 5-HT content as well as its metabolite 5-HIAA were increased

  11. Effect of deltamethrin on the release of catecholamines and its related effect on some sex hormones in adult male albino rats

    International Nuclear Information System (INIS)

    The oral administration of 1/5 LD50 of deltamethrin for 15 days resulted in an increase in Na+ and Ca++ ions concentrations, whereas it resulted in significant decreases in norepinephrine (NE) and dopamin (DA) contents in all tested brain areas (cerebellum, pans + medulla oblongata, striatum, cerebral cortex, hypothalamus, midbrain and hippocampus) of adult male albino rats at most time intervals. Deltamethrin also resulted in significant decreases of serum leutinizing hormone (LH) and testosterone levels in adult male albino rats. It could be concluded from the present results that deltamethrin resulted in significant increases in Na+ and Ca++ ions concentration. This observation might be due, in part, to an increase of the intracellular Na+ flow through its binding to Na+ ions channels and prolonging the opening time. Also, deltamethrin may stimulate the activity of protein kinase C/phosphoinositide that results in an increase of the intracellular concentrations ofinositol I, 4, 5-triphosphate (IPS) and free Ca++ ions. The increment in intracellular Ca+ ions led to an increase in the release of neurotransmitters by exocytosis, thai eventually decreased the contents of NE and DA in pre-synaptic cells. It is also clear that deltamethrin may act on the hypothalamus-pituitary axis. The decrement in DA content in hypothalamus led to decrease in the release of leutinizing hormone releasing hormone (LHRH) which resulted in decreasing in LH and testosterone levels in serum of the treated rats

  12. Salvia aegyptiaca as a Potential Herb for Ameliorating the Acute Toxicity Induced by Fenvalerate in Adult Male Albino Rats

    International Nuclear Information System (INIS)

    After fen valerate and/or Salvia aegyptiaca administration to male albino rats, fenvalerate caused a reduction in liver enzymes activity in liver homogenate with a percent change recording -24.1, -21.94 and-30.46 %, after 7 days, for ALT, AST and ALP, respectively .. Moreover, it increased the total protein and albumin at the same period. On day 7, fenvalerate increased the levels of serum ALT, AST and ALP by 351. 24, 164.60 and 119.78%, respectively. On the contrary, fenvalerate reduced the serum levels of total protein and albumin. Significant increase was observed in both creatinine (58.62%) and blood urea (47.41 %) after 7 days, whereas, serum T3 and T4 recorded a percentage change of -3.0.18 and -51.45%, respectively. An increase in GABA content in 7 brain areas was noticed after daily oral administration of fenvalerate, showing that GABA content in 'the cortex was the most affected recording, 191.43% change from control on the 7th day. Daily oral administration of 2 g/kg body weight of Salvia aegyptiaca extract alone or after fenvalerate caused a gradual decrease in ALT, AST and ALP enzyme activity as well as in total protein and albumin content in both liver homogenate and serum, on the 7th day. Salvia extract decreased serum creatinine and blood urea throughout the experimental period. No statistically significant changes in T3 and T4 levels were observed in animals that received salvia extract alone. On the other hand, salvia improved T3 and T4 levels after it was delivered post fenvalerate administration, bringing the hormonal levels near to that of control. Moreover, salvia extract caused a significant decrease in GABA content throughout the experimental period. However, animals that received combined treatment (fenvalerate + salvia) showed that salvia reduced the elevation that occurred in GABA content as a result of fenvalerate administration in all brain areas under investigation. From the current investigation, it could be recommended that, the duration of exposure as well as the given dose have to be planned carefully if salvia has to be taken as a potential herb for treatment. Further studies have to be undertaken to better elucidate the mode of action of salvia and to extract compounds with potential drug treatment

    Full Text Available Aluminium (Al is one of the most abundant and important elements in the environment. In recent years, the production of this metal and its toxicity increased with its discharge into the environment. This study was designed to evaluate the effect of Al intake toxicity in liver and kidney tissues of albino rats and the role of zinc as a protective agent against Al toxicity. Fourty five male albino rats were divided into equal three groups. The first group of animals was considered as control. The animals in the second group were given (50mg/kg/day of Al sulphate orally using gastric tube for 45 day. Third group were given Al sulphate (50mg/kg/day followed by zinc sulphate (50mg/kg/day orally as well as samples of liver and kidney tissues were obtained after 15, 30, 45 days of last doses respectively. Paraffin sections (5m were prepared for histological study stained with Haematoxylin & Eosin. The obtained histological results of the histological study of the second group showed that there were congested blood sinusoids and swelling of some hepatocytes within cytoplasm in which there were vacuoles, fragmented nuclei with some cellular infiltration. Kidney tissue showed shrinkage of some glomeruli and distortion of the tubular epithelial cells. Results in the third group, where zinc sulphate was added, showed amelioration and improvement in both liver and kidney tissues.

    Full Text Available A preliminary study to evaluate if long term treatment of Methanol Sub-Fraction (MSF of the seeds of Carica papaya as a male contraceptive would develop neoplastic lesions in vital organs was carried out in albino rats at 50, 250 and 500 mg kg-1 b.wt. day-1 for a period of 24 months, with a minimum dose being one therapeutic dose. Pre-terminal deaths, 45% in males and 48% in females, well within the acceptance limit, were reported to be age related and not treatment related, resulted due to general/respiratory/gastrointestinal/ urogenital disorders in both males and females of control and treated animals. Skin peeling, withering of fur leaving skin patches were observed in few of the animals after 18 months of treatment. Absence of spermatozoa in the cauda epididymis was evident in all the treated animals. No major structural changes compared to control were evident in the vital organs. Serum testosterone, serum electrolytes, tissue biochemical, hematology and clinical chemistry were comparable to those of control animals, suggesting no adverse effect of the test substance following long term treatment. The results provided evidence that the methanol sub-fraction of the seeds of Carica papaya does not lead any development of neoplastic lesion following life term treatment for 24 months in rats and is safe enough to be permitted for further trials as a male contraceptive.

  19. the Early Effects of Gamma radiation on the diurnal changes of Some Biochemical Parameters and the Role of ?-lipoic acid as an Antioxidant in Male Albino rats

    International Nuclear Information System (INIS)

    In mammals most of the physiological and behavioral systems such as sleep-wake cycle, cardiovascular activity, endocrine system, blood pressure, body temperature and hepatic metabolism are regulated by the circadian clock. The aim of the present work was to investigate the disturbances induced after gamma irradiation on the metabolic diurnal rhythm and the role of ?-alpha lipoic acid (ALA) in preventing/or decreasing these disorders in rat. Male Swiss albino rats were divided into 4 groups, one of which served as a normal control group, the second group was exposed to a single whole body gamma radiation dose of 6Gy, the third group was treated by gavage with ALA 100 mg/kg/day for 20 days and the fourth one was orally administered with ALA 100 mg/kg/day for 20 days before whole body gamma radiation at a dose of 6Gy. Rats were irradiated at 10 am and sacrificed at 11 am, 12 pm, 1 pm and 2 pm and then the biochemical analyses were performed. The results showed a significant increase in the level of lipid peroxidation products (MDA) at all time intervals. A significant increase was recorded also in the amount of free radicals at 11 am and 2 pm, and pyruvic acid level at 12 pm and 2 pm. A significant reduction of glutathione level (GSH) was recorded at 12 pm, 1 pm and 2 pm in the liver of the irradiated rats. Furthermore, a significant increase was registered in blood glucose level and blood aminotransferase activities (AST, ALT) in irradiated rats. Administration of ALA has significantly attenuated the radiation induced oxidative damage. It could be concluded that the biochemical changes induced by whole body gamma irradiation of rats are dependent on the circadian cycle. Further investigations are necessary to understand these complicated relations.

  20. Efficiency of lycopene extracted from tomato pomace as antioxidant against gamma irradiation hazards in male albino rats

    International Nuclear Information System (INIS)

    Nowadays, increasing attention has been given to the roles of free radicals generated through oxidative stres. The present study aims to evaluate the antioxidative role lycopene extracted from tomato processing wastes or pomace against hazards induced by gamma irradiation. Male rats were adminstered lycopene by a daily intragastric gavage(0.24mg/rat/day) or supplemented in a standard casein diet (6.5 Gy) of whole body gamma radiation. Lipid peroxides (MDA) reduced ghutathione (GSH) and superoxide dismutase activity (SOD) were determined in liver homogenate, as well as serum levels of alanine aminotransferase (ALT). asparate aminotransferase (AST), toral protein, albumin, globulin and A/G ratio were investigated 2 and 13 days post irradiation and/or lycopene administration. The results revealed that exposure to ionizing radiation resulted in significant elevation in MDA, ALT,AST, albumin levels and A/G ratio. Meanwhile, radiation exposure caused significant reduction in weight gain, SOD activity, GSH, total protein and globulin levels

    Full Text Available Tramadol is a synthetic opioid analgesic. It is commonly prescribed for moderate to severe pain, becoming abused more popular among teens in most countries. Paracetamol as anti-inflammatory drugs (acetaminophen (APAP is widely used as an analgesic and antipyretic agent. Meanwhile, tramadol/acetaminophen (tramacet is effective in acute or chronic moderate-to-moderately severe pain. In comparative study, the current investigation threw the light on the effect of over doses of tramadol and/or APAP on the immune function and hepatocytes in adult male Sprague-Dawley rats. Material and methods: Treated rats received oral doses of each drug for 15 consecutive days and after last treatment, they kept three days later for withdrawal studies. The rats were divided into four treatment groups, in the first group, rats received saline and used as control. The second, third and fourth groups treated with tramadol (45 mg/kg, tramadol/APAP (45/450 mg/kg, APAP (450 mg/kg respectively, once a-day at the first week and ending with 90, 90/900, 900 mg/kg at the second week. Rats were sacrificed at the end of the first, second weeks and three days of last treatment. Results: Daily doses of tramadol and /or APAP exposure in rats decreased the cellularity of spleen. Moreover, phagocytic and killing of S. aureus by PMN and macrophage cells caused a highly significant decrease in treated groups. IFN- was reduced in a statistically different treated group of rats. Serum IL-10 was unaffected by any of the treatment regimens but increased only in tramadol/APAP treated rats. Spleen histology exhibited mild pathological alteration with different injures between treated groups. Splenic white pulp accompanied by ill deformed which reflected the reduction of white pulp zones, thickened vasculature in the splenic net work, fibrous trabeculae become prominent feature, where splenic red pulp occupied large areas of the splenic network with predominant edema and megakaryocytes. On the other hand, the effect of tramadol and/or APAP induced DNA alterations of hepatocytes in dose dependent pattern as elucidated by dendrogramatic analysis. Liver histopathological changes of treated groups included vacuolated hepatocytes, dilated sinusoid with proliferated Kupffer cells; atrophied hepatocytes with nuclei reduced in size and darkly stained. Many areas of hepatocytes showed loss of architecture, congested central vein, expanded portal area with edema and inflammatory reaction. Conclusion: It could be concluded that the effect of tramadol/APAP induced anti-inflammatory cytokines than tramadol and APAP alone. Tramadol and/or APAP may display severe pathological consequences of hepatocytes. These hepatic lesions may be caused impairment of the liver function.

    Full Text Available The acute and sub-chronic toxicities of ulcer fast and reg; (UF - A commercial bi-herbal formula prepared with Alstonia boonei and Xylopia aethiopica in male Wistar albino rats was evaluated. There was no mortality in rats administered 2000 mg/kg body weight (BW of UF in an acute toxicity study. A significant (p and #8804;0.05 increase in daily consumption of feed and fluid intake in experimental rats after 28 days was recorded followed by a progressive increase in BW of rats administered 50, 100 and 200 mg/kg BW of UF in a dose-dependent manner. Alanine amino transferase, aspartate amino transferase, alkaline phosphatase, lactate dehydrogenase, triacylglycerides and creatinine increased significantly (p and #8804;0.05 in rats treated with UF, whereas urea and fasting blood sugar decreased significantly (p and #8804;0.05 in a dose-dependent manner when compared with control. There was a marginal decrease in serum calcium ion and phosphate ion following the administration of UF when compared with control. Packed cell volume and hemoglobin decreased significantly (p and #8804;0.05 in rats treated with UF, whereas white blood cell increased significantly (p and #8804;0.05 in a dose-dependent manner when compared with control. Histological examination of the liver, kidney, heart and lungs showed normal architecture in control group, whereas hepatocytes of rats treated with 50, 100 and 200 mg/kg BW of UF were characterized by slight periportal fatty change, marked change and ballooning degeneration. Heart muscle of rats treated with 200mg/kg BW of UF showed slight inflammation while histological examination of the lungs showed areas of interstitium damage and diffuse alveolar damage in rats treated with UF. In conclusion, indiscriminate administration of UF could be of public health concern and long-term exposure may cause a significant potential health risk.

    Nanoscience and Nanotechnology have found their way in the fields of pharmacology and medicine. The conjugation of drug to nanoparticles combines the properties of both. In this study, gold nanoparticle (GNP) was conjugated with NKCT1, a cytotoxic protein toxin from Indian cobra venom for evaluation of anti-arthritic activity and toxicity in experimental animal models. GNP conjugated NKCT1 (GNP-NKCT1) synthesized by NaBH4 reduction method was stable at room temperature (25 +/- 2 degrees C), pH 7.2. Hydrodynamic size of GNP-NKCT1 was 68-122 nm. Arthritis was developed by Freund's complete adjuvant induction in male albino rats and treatment was done with NKCT1/GNP-NKCT1/standard drug. The paw/ankle swelling, urinary markers, serum markers and cytokines were changed significantly in arthritic control rats which were restored after GNP-NKCT1 treatment. Acute toxicity study revealed that GNP conjugation increased the minimum lethal dose value of NKCT1 and partially reduced the NKCT1 induced increase of the serum biochemical tissue injury markers. Histopathological study showed partial restoration of toxic effect in kidney tissue after GNP conjugation. Normal lymphocyte count in culture was in the order of GNP-NKCT1 > NKCT1 > Indomethacine treatment. The present study confirmed that GNP conjugation increased the antiarthritic activity and decreased toxicity profile of NKCT1. PMID:25141538

  4. Protective Effect of Phoenix dactylifera-L Extracts against Radiation-Induced Cardio-Toxicity and Some Biochemical Changes in Male Albino Rats

    International Nuclear Information System (INIS)

    The Antioxidant properties of the date palm fruit; Phoenix dactylifera-L in mitigation of cellular injury following free radicals release by ionizing radiation has been investigated. Forty-eight male albino rats divided equally into 6 groups were used in this study. Group 1 (G.1) acted as control, G.2 received date extract orally (4 ml/ kg/ day) for 21 days, G.3 was exposed to a single dose of gamma irradiation (6 Gy), G.4 received date extract orally at an identical dose and duration to G.2 and irradiation to G.3, G.5 received the daily date extract for 7 days post irradiation and G.6 received the daily date extract for 21 days before and for 7 days after irradiation. Heart tissue was examined histologically and biochemical testing for total cholesterol (TC), triglycerides (TG), high and low density lipoprotein-cholesterol (HDL-C and LDL-C), creatine kinase (CK), creatine kinase-MB (CK-MB) and lactate dehydrogenase (LDH) was performed for each rat group. Data from the investigation showed that gamma irradiation caused histopathological damage to the heart tissue and disturbances in most parameters related to cardiac function. Administration of date extracts pre-irradiation provided evidence of a potential protective effect against irradiation hazard

  5. Role of Omega 3 fatty acids on radiation-induced oxidative and structural damage in different tissues of male albino rats

    International Nuclear Information System (INIS)

    Omega-3 fatty acids play a critical role in the development and function of the reproductive and central nervous systems. The aim of this study is to evaluate the effect of omega-3 fatty acids supplementation on lipid peroxidation and antioxidant enzyme levels associated with histopathologic changes induced by gamma irradiation in the testis and brain of male albino rats. Rats were whole body exposed to radiation at a single dose of 3 Gy. Omega-3 fatty acids (0.4 gm/kg b wt/day) were given to rats, by gavages, for 15 consecutive days before irradiation and for 15 days after irradiation. Rats were sacrificed one and 15 days post irradiation .Biochemical analysis of testis and cerebral cortex samples showed that irradiation induced a significant increase in xanthine oxidase (XO) activity and lipid peroxidation end product malondialdehyde (MDA) and a decrease in the content of reduced glutathione (GSH) and activity of antioxidant enzymes; glutathione peroxidase (GPX), superoxide dismutase (SOD) and catalase (CAT).Histological examination of testis and cerebral cortex tissues showed spermatogonia degeneration, apoptosis and necrosis in the testis and neurons cell bodies with ill defined and even ruptured cell membrane and damaged blood capillaries in the cerebral cortex. Omega-3 administration has attenuated the toxic effects of radiation by decreasing the levels of MDA, and XO, and increasing the activity of endogenous antioxidant enzymes, which was associated with amelioration of the histological injury markers in both testis and cerebral cortex. It could be postulated that omega-3 fatty acids as a multi-functional dietary supplement could exert a modulatory role in radiation- induced testis and cerebral cortex biochemical and histological changes through its antioxidant properties.

  6. Effect Of The ORGANOCHLORINE Insecticide Endrin On Some Amino Acids And Thyroid Hormones In Male Albino Rats

    International Nuclear Information System (INIS)

    Oral administration of single doses of organo chlorine insecticide endrin to rats at levels of 10, 30 and 50 % of the LD50 each for 2, 4, 6 and 8 days was employed to evaluate its dose dependent and toxic effect on triiodothyronine (T3), thyroxine (T4) levels and some amino acids contents.Treatment with 10% LD50 of endrin did not induce any significant change in serum T3 or T4 level in male rats along the experimental period. Endrin induced significant increases in T3 and T4 levels at doses of 30 and 50% on days 2 and 4. At the same doses, endrin induced significant decreases in T3 and T4 levels on day 6. On day 8, the dose 30% resulted in a decrease in T4 level, and the dose 50% decreased the levels of T3 and T4.. Endrin resulted in significant alterations in amino acids contents and the most effect was noticed on days 6 and 8 at the three selected doses.

    Full Text Available This study evaluates qualitative and quantitative phytochemical properties of Abrus precatorius leaves. The vitamins and therapeutic effect of methanol extract against tetrachloride (CCl4 induced liver damage in male Wistar albino rats. The results of phytochemical and vitamins indicates richness in saponins, tannins, alkaloids and flavonoids with value 30.05±0.22%, while vitamins such as thiamine, riboflavin, niacin, antioxidant and vitamins A, C and E was quantified. The liver damage was observed in the animals with significant increase in ALT, AST and ALP following the in traperitoneal administration of CCl4. The methanol extract caused significant decrease (p4 but were not treated. The extract showed potentials to mopping-up of free radicals generated by CCl4. The extract reduced lipid peroxidation in concentration dependent manner. The findings suggests that the extract have the capacity to improving liver functions and liver regeneration at high concentration. The extracts are safe for consumption, abundant phytochemicals and antioxidant vitamins could offer reasonable protections against oxidative stress.

    Full Text Available Introduction: Physical and Psychological stresses are believed to reduce sexual functions, resulting fromneurotransmission changes in various erectile response pathways and reduced blood flow in genital organs.Intake of alcohol depends on numerous genetic and environmental factors. Stress has long been thought to influence the alcohol drinking in humans. Forced swimming in laboratory animals has been widely used as a model of stress to study the physiological changes and the capacity of the organism in response to stress. Aim: 1. To assess the effect of forced swimming stress on seminal fluid profile, Serum testosterone level, Testicular lipid peroxidation levels. 2. To assess the effect of Vitamin E on stress induced changes. Method: Adult male albino rats weighing 200 – 220 g, aged 12-15 weeks were used in this study. The animals were randomly divided into four groups of 6 animals each. Group1 (control received distilled water, Group 2 (Forced Swimming Stress received distilled water Group 3: subjected to Forced Swimming stress with 20% alcohol intake p.o. Group 4: Swimming stress with 20% alcohol treated with Vitamin E(200mg/kg/day orally. The following parameters were studied in all groups 1. Body weight. 2. Sperm count Motility and Life /death Ratio (SLDR. 3. Serum Testosterone 4. Testicular Malondialdehyde level (MDA. Results: Forced swimming stress caused loss in body wt, reduction in sperm count, motility and SLDR in sperm analysis, reduction in serum testosterone and increase testicular MDA levels compared to control. All the changes were statistically significant. When alcohol was added along with forced swimming it caused further loss in body wt, sperm count, motility and SLDR, serum testosterone level and slightly further increase in MDA levels. These observations were also statistically significant. In case of group IV in which Vitamin E was administered long with stress with alcohol it showed a trend of reversal phenomenon of stress and alcohol induced change (Group III exhibited by gain in body wt, increase sperm count, motility and SLDR, serum testosterone and decrease in MDA level. All the results were statically significant except serum testosterone. Conclusion: Force swimming indicates that swimming is an effective model for producing stress in albino rats. The stress induced changes were further accentuated by addition of ethyl alcohol. However Vit E treatment reverses the effect of stress and alcohol.

    Full Text Available In this study, the neuroprotective effect of the extract of ginger (Zingiber officinale was investigated against MSG-induced neurotoxicity of male albino rat. The daily dose (4 mg kg-1 b.wt. i.p. injection of pure monosodium glutamate (MSG for 30 days and subsequent withdrawal caused a significant decrease in epinephrine (E, norepinephrine (NE, dopamine (DA and serotonin (5-HT content all tested areas (cerebellum, brainstem, striatum, cerebral cortex, hypothalamus and hippocampus at most of the time intervals studied. This is may be due to activation of glutamate receptors, which led to increased the intracellular concentration of Ca+2 ions, so the release of neurotransmitters is increased and the content of monoamines is decreased. After the withdrawal, the decrease in monoamines levels remained in striatum, cerebral cortex and hypothalamus, this may be due to the region specific effect of monosodium glutamate. whereas, daily dose (100 mg kg-1 b.wt. i.p., injection of Ginger (Zingiber officinale root extract for 30 days and subsequent withdrawal caused a significant increased in epinephrine (E, norepinephrine (NE, dopamine (DA and serotonin (5-HT content all tested areas at most of the time intervals studied. This is may be due to inhibition of 5HT-3-receptor effects at the same time the extract blockade of Ca+2 channel, as result the release of neurotransmitter is decreased and the content is increased. After the extract withdrawal, the increase in monoamine levels remained in brainstem, striatum and hippocampus, this may be due to the region specific effect of the extract. The coadninisration of monosodium glutamate and ginger root extract caused increased in monoamine content in most of the tested brain areas at different time intervals. This is may be due to partly attributable to an antagonistic action of ginger root extracts on monosodium glutamate effect, so the monoamines content was increased. From these results, we can say that the ginger extract has a neuroprotective role against monosodium glutamate toxicity effect.

  11. THE PROTECTIVE ROLE OF ONION OIL (ALLIUM CEPA LINN) AGAINST RADIATION-INDUCED HAZARDS IN MALE ALBINO RATS

    International Nuclear Information System (INIS)

    Radiation poses a major currently irresolvable risk for human. Onion is a major source of dietary flavonoids. The present investigation was carried out to study the protective effects of treating rats with onion oil (150 mg/kg body weight) for consecutive 3 weeks against damages induced by whole body gamma irradiation (7 Gy). Exposure of rats to gamma irradiation caused a significant increase in levels of serum glucose, cholesterol, triglycerides as well as activities of AST, ALT, alkaline phosphatase, creatinine, uric acid and lipid peroxides. Exposure to gamma rays resulted in an increase in the mentioned parameters accompanied by a decrease in urea, total protein, albumin, glutathione content, superoxide dismutase and catalase activities. It could be concluded that onion oil capable of reducing the biological hazards induced by gamma irradiation

  12. Squalene Modulates Radiation-Induced Structural, Ultrastructural And Biochemical Changes In Cardiac Muscles Of Male Albino Rats

    International Nuclear Information System (INIS)

    The failing heart represents an enormous clinical problem and is a major cause of death throughout the world. Hyperlipidemia and oxidative stress have been shown to contribute to heart failure. Squalene is a remarkable bioactive substance that belongs to a class of antioxidants called isoprenoids, which neutralize the harmful effect of excessive free radicals production in the body.The present study was designed to determine the possible protective effect of squalene against oxidative cardiac muscle damage induced by gamma irradiation.Rats were treated daily by gavage with 0.4 ml/kg squalene for 42 days before whole body gamma irradiation at a dose of 4 Gy and continued until animals were sacrificed 3 days post irradiation.Histological examination of cardiac muscles sections by using light and electron microscopes showed that exposure of rats to ionizing radiation has provoked a severe architecture damage such as necrotic nuclei, nuclei located at the periphery, alteration in chromatin distribution, ruptured cell and mitochondrial membranes, cristae of mitochondria disappeared, sticking mitochondria and ruptured myofibers. Structural and ultra-structural changes were associated with severe oxidative stress. Significant increase of lipid peroxidation products (malondialdehyde) (MDA) along with reduction in the activity of the antioxidant enzymes; superoxide dismutase (SOD) and catalse (CAT), and glutathione content (GSH), were recorded.Treatment of rats with squalene has significantly attenuated the radiation-induced oxidative damage and histopathological changes in cardiac muscle which was substantiated by a significant amelioration in the activity of plasma lactate dehydrogenase (LDH), creatine phosphokinase (CPK) and aspartate transaminase (AST). Furthermore, administration of squalene to rats has adjusted the radiation-induced increase in plasma triglycerides (TG), total cholesterol (TC) and low density lipoprotein-cholesterol (LDL-C). Based on these results, it could be concluded that squalene through its antioxidant properties might be capable of attenuating radiation-induced damage to cardiac muscles.

    Full Text Available Daily exposure to heat stress causes sustained elevation of blood pressure in rats. It is known that the renin-angiotensin system is activated during episodes of behavioral stress, and the purpose of this work was to assess the action of captopril in the development of stress induced hypertension in rats. Animals were divided into four groups. The first group served as a control, while the other groups were subjected to heat stress of 40C and high hamidity of 80% for 10 successive days. The second group was served as heat stress, while the third and the fourth groups were received low and high doses of captopril (0.7 & 1.4 mg/kg. b.wt., respectively. After 10 days of treatment, half of animals from each group were decapitated and brain, liver, muscle, heart and kidney were separated and analysed. The other half of animals were left for another 10 days without any additional treatment for recovery.The results revealed a significant decrease in total protein of liver, heart, kidney, total lipids of heart, muscle and brain and total cholesterol of liver. On the other hand, insignificant change was noticed in muscle and brain total protein. Similarly, AST and ALT activities were also within the normal values for all the organs examined.Results exhibited that renin-angiotensin system may be important in the development of stress-induced hypertension in rats.

    Full Text Available Liver disease appears to be increase. Part of this increase may be due to our frequent contact with chemicals and other environmental pollutants. The amount of medicne consumed has increased greatly which could be danger to the liver. The hepatoprotective flavonoid, silymarin (7.56 mg/Kg b. wt. and ginger (Zingiber officinale (1% of diet for 4 weeks were used to ameliorate the liver injury in rats intoxicated with carbon tetrachloride (CCL4 , single acute dose 4 ml/ Kg b. wt. of 50% v/v CCL4 in olive oil, subcutaneous. The obtained results showed that CCL4 decreased serum and liver total protein and albumin. Also reduced glutathione content. The antioxidant enzymes; glutathione-S-transferase, superoxide dismutase and catalase activity decreased in the liver of CCL4 toxicity group. On the other hand, CCL4 toxicity increased serum and liver bilirubin, total lipid and total cholestertol levels. In addition, liver function (aspartate aminotransferase, alanine aminotransferase and alkaline phosphatase and liver lipid peroxidation content showed significant increase in the CCL4 treated group. Previous parameters turned back to normal values in carbon tetrachloride intoxicated rats after treating with silymarin and/ or ginger for one month. Meanwhile, the most interesting effect was induced by a combination of silymarin and ginger. Hence, the present findings will provide a potential scope for future use of ginger for the treatment of liver disorders.

  16. Extract Against Toxic Sodium The Protective Role of Grape Seed Proanthocyanidins Nitrites and Gamma Irradiation Induced Histological Changes in Intestine and Urinary Bladder of Male Albino Rats

    International Nuclear Information System (INIS)

    Proanthocyanidins (a grape seed extract) possess a broad spectrum of biological activities. The present study was performed to investigate the effect of gamma radiation exposure and toxic sodium nitrites induced oxidative stress on the intestine and urinary bladder histologically and also to evaluate the possible protective role of proanthocyanidins. Seventy adult male albino rats, each weighing 95-105 g were used and divided into 7 groups as follows: The first group represents the control group. The second experimental group were exposed to 7 Gy gamma-rays as a single dose and sacrificed on the 7th day. The third experimental group received by a stomach tube daily 50 mg/kg b.wt of sodium nitrite for 4 weeks. The fourth experimental group received proanthocyanidins, Grape seed extracts (antioxidant) (100 mg/kg) body wt.) daily for seven days before irradiation and the continued for 14 days post irradiation. The fifth group of animals received grape seed extract after being exposed to gamma radiation for two weeks, while the sixth experimental group received the same antioxidant for seven days before and after received sodium nitrite (50 mg/kg) daily for 4 weeks. Finally, the seventh experimental groups was treated with the same antioxidant in same dose and time after received sodium nitrite for 4 weeks. The animals were then sacrificed on the end of each experimental duration. The results revealed that both gamma-radiation and sodium nitrite induced different histological changes in the intestine and urinary bladder of irradiated and sodium nitrite received animals. The effect of gamma radiation exposure showed marked degeneration of intestinal villi, vaculation in the lining epithelium cells and karyolytic nuclei. In addition, using sodium nitrite lead to necrosis of intestinal glandular cells. The effect of gamma radiation on urinary bladder was presented by, hyperplasia and vaculation of mucosal epithelium, congestion of blood capillaries. Rats from nitrite group revealed activation of glandular epithelium. The animals were treated with proanthocyanidins, the tissues revealed histological structure almost similar to the control group. This histological observations were performed to evaluate the efficiency of proanthocyanidins (a grape seed extract), through its antioxidant properties which might attenuate radiation or nitrite toxicity.

  17. Effect of Omega-3 Fatty Acids on Neurotransmitters Level in the Brain of Male Albino Rats Exposed to Gamma Irradiation

    International Nuclear Information System (INIS)

    The omega-3 fatty acids are essential dietary nutrients, and one of their important roles is providing docosahexaenoic acid (DHA) and eicosapentaenoic acid (EPA) for growth and function of nervous tissue. Reduced level of DHA in the brain induce dramatic changes in brain function including changes in size of neurons as well as changes in learning and memory. The objective of this study was to evaluate the role of fish oil rich in omega-3 fatty acids on ?-radiation-induced physiological changes in the brain cerebral hemispheres. Omega-3 fatty acids was supplemented daily by gavages to rats at a dose of 400 mg/ kg body wt for 7 days pre- and 21 days post-exposure to whole body fractionated gamma rays at doses of 2 Gy/week up to a total dose of 8 Gy. The results demonstrated that whole body ?-irradiation induced oxidative stress, de - creased the main polyunsaturated fatty acids; DHA and EPA, and induced neurotransmitters alteration in brain tissues. Oxidative stress was manifested by a significant increase in lipid peroxidation product malondialdehyde (MDA) and decrease in the activity of antioxidant enzymes, superoxide dismutase (SOD), catalase (CAT) and glutathione peroxidase (GSH-Px). Oxidative stress was accompanied by alterations in the level of the neurotransmitters manifested by a significant increase of glutamic and aspartic and a significant decrease of serotonin (5-HT) levels in brain cerebral hemispheres. Rats receiving fish oil 7 days before and 21 days after exposure to ?-radiation showed significant improvement in the levels of EPA and DHA associated with significant amelioration of oxidative stress and neurotransmitters alteration. It is concluded that fish oil protect the brain from radiation-induced physiological changes by protecting brain cellular membranes through counteracting the decrease of omega-3 fatty acids and minimizing oxidative stress

  18. Effect of acetyl salicylic acid (aspirin) and Prostaglandins on thyroid tissue and carbohydrate metabolism in liver of male albino rats

    International Nuclear Information System (INIS)

    Aspirin, both in chronic and acute doses, led to a considerable decrease in percentage uptake of labelled iodine (Na131I) and serum protein-bound iodine by the thyroid gland whereas prostaglandins (PGs) did not exhibit any significant effect on both the parameters. Simultaneous administration of aspirin and PGs caused a significant decrease in the two parameters, and on withdrawal of aspirin from the diet the two parameters were restored to normal levels, thus suggesting that the effect of aspirin on thyroid is direct and reversible. Aspirin, both in acute and chronic doses, effected decrease in glycogen levels, in vivo and in vitro incorporation of [U-14C] glucose into glycogen, and glycogen synthetase activity in the liver of both fed, and fasting, rat. Prostaglandins, on the other hand, resulted in a significant increase in the three parameters, thus enhancing the rate of liver glycogenesis. Normal levels were restored when both aspirin and PGs were given together. Withdrawal of aspirin also restored normal hepatic glycogenesis. Significant reduction in the activities of hepatic gluconeogenic enzymes, viz. glucose 6-phosphatase, fructose 1,6-diphosphatase, phosphopyruvate carboxylase, pyruvate carboxylase, aspartate aminotransferase and glutamate dehydrogenase was observed due to chronic and acute administration of aspirin and PGs were devoid of any significant effect on gluconeogenic enzymes, thus ruling out the mediation of PGs.

    The objective of the present study was to evaluate the possible protective effects of Tribulus terrestris fruit aqueous extract (TTFAEt) on lipid profile and oxidative stress in isoproterenol (ISO) induced myocardial necrosis in albino Wistar rats. Albino Wistar rats were divided into normal control, TTFAEt alone treated, ISO control and pretreated (TTFAEt+ISO) groups. The extract was administered at a dose of 50 mg/kg body weight for 40 days orally by gavage and ISO was administered at a dose of 85 mg/kg body weight for two consecutive days intraperitoneally at an interval of 24 h. ISO induced myocardial infarction (MI) was confirmed by disturbances in serum lipid profile, heart tissue lipid peroxidation and antioxidant enzyme levels. There was a significant increase in the levels of serum total cholesterol (32.60 %), triglycerides (41.30 %), very low density lipoproteins (81.81 %), low density lipoproteins (84%) and phospholipids (38.88 %) and a significant decrease in the levels of high density lipoproteins (33.33 %) in the ISO control group when compared to normal controls. Additionally, there is a significant decrease in the levels of heart tissue antioxidant enzymes such as superoxide dismutase, catalase, glutathione reductase, glutathione peroxidase and depletion of reduced glutathione, which indicates enhanced lipid peroxidation(172 %). Pretreatment with extract significantly showed a protective effect against ISO altered lipid profile, lipid peroxidation and antioxidant enzyme levels. The present study showed therapeutic effect of TTFAEt on lipid profile and oxidative stress in isoproterenol (ISO) induced myocardial necrosis in experimental rats. PMID:26417233

Morphometric data such as body weight (BDYWT, tail length (TL, body length from nose to anus (BLNA, body length from nose to tail tip (BLNT, tail circumference (TC, tail diameter (TD, and ear length (EL were collected from fifty live Albino rats involving 28 females and 22 males. The collected data were evaluated using regression analysis, correlation and independent-sample t-test. There was high significant (P r2 values ranging from 0.264 to 0.81. Regression analysis with high r2 value could be exploited in predicting many morphometric traits with great accuracy with the body weight serving as the explanatory or predictor variable. This research also suggested that male and female Albino rats have very similar morphometric characters as the results of independent-samples t-test showed.

    Polypropylene mesh is commonly used in the treatment of abdominal hernia. Different approaches were addressed to improve their tissue integration and consequently reduce long-term complications. This study aimed to investigate the effect of alpha-lipoic acid (ALA) co-administration on structural and immunohistochemical (IHC) changes in the subcutaneous tissues of the anterior abdominal wall of the adult rat in response to polypropylene mesh implantation. Forty adult male albino rats were divided into: group I (control), group II (receiving ALA), group III (polypropylene mesh implantation) and group IV (mesh implantation + ALA co-administration). After 4 weeks, subcutaneous tissue samples were prepared for light microscopy and IHC study of CD34 as a marker for angiogenesis. In groups I and II rats, positive CD34 expression was demonstrated by IHC reaction, localized to endothelial cells lining small blood vessels. Group III showed an excess inflammatory reaction, deposition of both regular and irregularly arranged collagen fibres around mesh pores and few elastic fibres. CD34-positive was detected not only in cells lining small blood vessels but also in other cells scattered in the connective tissue indicating angiogenesis. In group IV, ALA co-administration resulted in less inflammatory reaction, regular collagen deposition, enhanced elastic fibres synthesis and a significant increase in CD34-positive cells and small blood vessels reflecting improved angiogenesis. ALA co-administration with polypropylene mesh implantation controlled the inflammatory reaction, helped regular collagen deposition, enhanced elastic fibres synthesis and improved angiogenesis in the subcutaneous tissue of anterior abdominal wall of adult albino rats, suggesting a possible role of ALA in optimizing mesh integration in subcutaneous tissue.

  8. Hepatotoxicity of ingested uranium in albino wistar rats

    International Nuclear Information System (INIS)

    Uranium exhibits both radiotoxic and chemotoxic properties. Common route of contamination is ingestion through drinking water. Uranium is mainly nephrotoxic and is also hepatotoxic to mammals including humans. The dose range at which it affects organs still remains in predicament. To study the effect of ingested uranium on enzymatic and histopathological changes of liver in albino wistar rats. Uranyl nitrate hexahydrate (UN) solutions were prepared at different concentrations in distilled water for administration. Healthy male and female albino wistar rats weighing 120±20 g were randomly divided into six groups, each group with five animals. Group 1 was the control. All the five treatment groups (group 2, group 3, group 4, group 5 and group 6) were orally administered with 0.156, 0.625, 2.5, 10 and 40 mg/kg/day of UN for 28 days duration. Blood samples collected on 29th day were analyzed for ?-glutamyltransferase (GGT), alkaline phosphatase (ALP), serum glutamic pyruvic transaminase (SGPT) and serum glutamic oxaloacetic transaminase (SGOT). In addition, histopathological examination of liver tissue was performed. Significant reduction by 61 and 46 % in GGT levels in female rats of groups 4 and 5 respectively while in male rats, increase of 55, 52 and 40 % in groups 3, 4 and 5 respectively were observed compared to control. In females, ALP levels were decreased by 38 % in group 2 and 29 % in group 4 while no changes were observed in males of control and test groups. SGPT level was decreased by 22 % in group 6 in females but increased by 29 and 35 % in groups 2 and 6 respectively in males, compared to control. In females, 25 % increase in SGOT levels in group 4 was observed, but decreased in group 5 and 6 by 26 and 22 % respectively. A 27 % increase in SGOT level in males was recorded in group 2 compared to control. No histopathological changes were observed in liver tissues of test groups or the control. Uranium causes dose-independent changes in key marker enzymes of liver function indicating hepatic damage. Conversely, no histopathological alterations were observed in liver tissues. (author)

    Emamectin benzoate (EB) is an avermectin insecticide used extensively in pest control on vegetable and field crops. Few studies have been done for evaluating adverse effects of EB. In the current study, we evaluated the toxic effects of EB on male rats and the possible ameliorative role of fennel essential oil (FEO). Thirty two male rats were randomly divided into 4 equal groups. All groups were treated orally with distilled water (control group), 0.5mlFEOkg(-1) BW (FEO group), 2.5mgEBkg(-1) BW (EB group), and 0.5mlFEOkg(-1) BW+2.5mgEBkg(-1) BW (FEO+EB group) for 28 days. The obtained results showed that EB treatment resulted in a significant decrease in body weight, body weight gain, RBC count, Hb concentration, % PCV, MCV and MCHC. Moreover, EB significantly decreased total leukocyte, lymphocyte, monocyte and platelet count but significantly increased granulocyte count. EB markedly decreased total protein, albumin, globulin, IgG and IgM concentrations with a significant increase in TNF-? secretion. EB had a negative impact on the liver as it significantly increased ALT, ALP, and MDA, while decreasing SOD activity. Regarding to the histopathological examination, EB treatment induced coagulative necrosis and blood vessels congestion of the liver in treated rats. Furthermore, it resulted in depletion and necrosis of the white pulp of the spleen in treated rats. The co-administration of FEO with EB, however, improved the majority of parameters studied, suggesting that FEO is an important substance in decreasing toxic effects of EB. PMID:25935540

  10. Pumpkin Seed Oil Attenuates Functional and Structural Disorders in Urogenital System of Male Albino Rats Induced by Whole Body Gamma Irradiation

    International Nuclear Information System (INIS)

    Pumpkin seeds have long been used for health benefits and the seed oil has been shown to contain active beneficial components that may protect from oxidative stress. The aim of the present study is to evaluate the modulator role of pumpkin seed oil (PSO) supplementation on gamma radiation induced changes in certain biochemical and histological abnormalities in both kidney and testes tissues. Male rats received 5Gy whole body gamma-irradiation delivered as 1 Gy day after day to result in a cumulative dose of 5 Gy. PSO was orally administered to rats (20mg/Kg body weight) for 20 consecutive days before irradiation and during the period of irradiation. On days seven and twenty one after the last irradiation dose, rats were sacrificed. Biochemical analysis in the serum revealed that PSO supplementation diminished the radiation-induced increase in the level of urea, creatinine , follicle stimulating hormone (FSH) and luteinizing hormone (LH). Significant amelioration of the radiation-induced decreases in calcium (Ca+2), potassium (K+) and testosterone levels were also recorded. PSO administration has attenuated the toxic effects of radiation by decreasing the level of lipid peroxides measured as thiobarbituric acid reactive substances (TBARS) and increasing the activity of endogenous antioxidant enzymes, superoxide dismutase (SOD) and catalase (CAT) and the content of glutathione (GSH). Histological observations of photomicrographs of kidney sections of irradiated rats showed amorphoid glomeruli, renal sclerosis and high content of inflammatory cells and fibroblasts, hemorrhage in glomeruli, ruptured proximal and distal convoluted tubules. Examination of testis tissues showed disappearance of seminiferous tubules, ruptured tunica albuginea, and degeneration of interstitial cells. PSO supplementation has obviously improved the radiation-induced histopathological changes in both tissues. It could be concluded that PSO can be used as a useful adjunct for maintaining the integrity of biochemical functions and restoring the original histological architecture of kidneys and testes after irradiation

    Full Text Available This study investigated the effect of long term consumption of Gongronema latifolium on some biochemical and histological parameters in male rats. Biochemical parameters evaluated included serum protein, haemoglobin, cholesterol, lipid peroxidation, white blood cells, glutathione-s-transferase, superoxide dismutase, alanine transaminase, aspartate transaminase and alkaline phosphatase. The histological changes of the liver, intestines and testes were examined. The long term feeding of a Gongronema latifolium -supplemented diet caused significant increases (p<0.05 in cholesterol, haemoglobin and white blood cells. The diet exhibited antioxidant properties by reducing lipid peroxidation and increasing superoxide dismutase activity. There was a significant increase (p<0.05 in glutathione-s-transferase and decrease in the liver enzymes namely Alanine transaminase, aspartate transaminase and alkaline phosphatase suggesting a role of Gongronema latifolium in detoxification and hepatoprotection. However, Gongronema latifolium -supplemented diet did not cause any significant changes in weight and serum protein. The histology of the hepatic plate appeared irregular while the portal tracts showed a lifted basement membrane and few inflammatory cells. The intestinal mucosa showed an elongated and broadened villi. There were no histological changes on the testes.

Again the hopes that traditional medicine and natural plants seem to trigger researchers in this area is yet to be discovered. This research was designed to compare the biochemical effects of some medicinal plants in alloxan-induced diabetic male Wistar rats using named plants that are best at lowering blood glucose and hyperlipidemia and ameliorating other complications of diabetes mellitus by methods of combined therapy. The results obtained showed 82% decrease in blood glucose concentration after the 10th hour to the fortieth hour. There was significant increase P 0.05 recorded in the glutathione peroxidase activity of E. globulus (100?mg/kg) when compared to the test groups of P. guajava (250?mg/kg) and X. aethiopica (250?mg/kg). Catalase activity showed significant increase P 0.05, there was no significant difference seen between test group and treated groups. Meanwhile, degree of significance was observed in other parameters analysed. The biochemical analysis conducted in this study showed positive result, attesting to facts from previous works. Though these individual plants extracts exhibited significant increase in amelorating diabetes complication and blood glucose control compared to glibenclamide, a synthetic antidiabetic drug. Greater performance was observed in the synergy groups. Therefore, a poly/combined formulation of these plants extracts yielded significant result as well as resolving some other complications associated with diabetics. PMID:25525518

  14. Effect of Electromagnetic Radiation Exposure on Histology and DNA Content of the Brain Cortex and Hypothalamus of Young and Adult Male Albino Rats

    International Nuclear Information System (INIS)

    Concerns have been raised regarding the potential adverse effects of exposure to electromagnetic radiation (EMR) arising from mobile phone. The present study investigates the effect of the daily exposure of adult and young rats to EMR for 1 hour (at a frequency of 900 MHz, a power density of 0.02 mW/cm2 and an average specific absorption rate of 1.165 W/kg) on the DNA content and tissue architecture of the cortex and hypothalamus of the rat brain. Both young and adult rats were sacrificed at two intervals, after 4 months of daily EMR exposure and after 1 month of stopping the exposure. The present results showed a significant increase in the DNA intensity of young and adult rats in both areas after 4 months of daily EMR exposure. However, decreased DNA content around the normal level was observed after one month of stopping the exposure. Light microscopic examination of irradiated rats revealed edema, vacuolation, necrosis and proliferated glial cells. Stopping EMR exposure showed mild amelioration in the structural damage of the cerebral cortex of young animals, however, most drastic changes still persisted in the other animals. In conclusion, these data may confirm the neurotoxic risks arising from the extensive use of mobile phones that may alter the brain histology and impair its function

    Full Text Available El metotrexato es ampliamente usado en la terapia de varias enfermedades malignas. El presente trabajo fue diseñado para investigar los cambios histológicos e histoquímicos del hígado de rata albina, después de administrar dicho fármaco. Se usaron 15 ratas albinas, machos, adultas, que fueron dividi [...] das en 3 grupos: El grupo I no tuvo tratamiento correspondiendo al control. A los grupos II y III se les administró, por vía intraperitoneal, una solución salina normal y metotrexato, respectivamente, con una dosificación de 0,5 mg por Kg de peso, dos veces por semana, con una duración total de 3, 6 y 9 semanas. Las ratas fueron sacrificadas y los hígados extraídos y procesados para los estudios histológico e histoquímico. El examen de los hígados del grupo III mostró infiltración celular mononuclear y un incremento en la cantidad de fibras colágenas en la vía portal. Hubo áreas focales de necrosis de células hepáticas con distorsión de la arquitectura hepática normal. Además, hubo un gradual y progresivo decrecimiento del contenido de glicógeno en los hepatocitos. La actividad de deshidrogenasa succínica y fosfatas alcalinas también disminuyó, pero sí hubo un aumento de la actividad de las fosfatasas ácidas en las áreas degeneradas y pérdida de actividades en áreas de necrosis celular masiva. En conclusión, inyecciones repetidas de metotrexato causan daño hepático de maginitud definida. Esta hepatotoxicidad progresó a medida que las dosis se fueron acumulando. El presente estudio muestra evidencias claras de la potencia citotóxica de este medicamento. Abstract in english Methotrexate (MTX) is widely used in the therapy of various types of malignancy. The present work was designed to investigate the histological and histochemical changes in the liver of albino rat following methotrexate administration. Fifteen adult male albino rats were used in the present work. The [...] y were divided into three main groups: Group I was kept without treatment and served as control. Groups II and III were given intraperitoneal injections of normal saline and MTX, respectively, at a dosage of (0.5 mg/Kg) twice weekly for total durations of 3, 6 and 9 weeks. The rats were sacrificed and the livers were excised and processed for histological and histochemical study. Examination of sections of the livers of group III showed mononuclear cell infiltration and an increase in the amount of collagen fibers in the portal tracts. There were focal areas of liver cell necrosis with distortion of the normal hepatic architecture. Moreover, there was a gradual and progressive decrease of glycogen content in the hepatocytes. Furthermore, succinic dehydrogenase and alkaline phosphatase activity were also decreased. In addition there was an increase in acid phosphatase activities in the degenerated areas and loss of activities in areas of massive cellular necrosis. It was concluded that repeated injections of MTX causes hepatic damage of a definite magnitude. This hepatotoxicity progressed with increasing cumulative doses of methotrexate. The present study provided further evidence to the cytotoxic potency of this antifolate

    International Nuclear Information System (INIS)

    Propolis (bee glue) is a sticky substance that is collected from plants by honeybees. Due to biological and pharmacological activities, it has been extensively used in folk medicine. The purpose of this study was to investigate the chemical composition, the antimicrobial activity and possible protective effects of ethanolic extract of propolis on carbon tetrachloride (CCl4)-induced biological damages in rats. The studied rats were allotted to four equal groups (6 rats each) : Group 1 served as control and was given the vehicle (Tween 80 dissolved in distilled water, 1:100 ) orally for 21 consecutive days after which they were sacrificed , group 2 treated orally with ethanolic extract of popolis (100?g/rat) for 21 successive days, group 3 ( CCl4 - treated group) administered orally with a single dose (0.5 ml/kg body weight) of carbon tetrachloride (mixed with an equal volume of olive oil) and group 4 (protected group) was treated with propolis extract (100?g/rat) for 21 successive days, after one hour of the last dose of the treatment, a single dose of CCl4 (0.5 ml/kg body weight) was given. Then all animals were sacrificed, 24 hr post experimental design period for each group. Our results revealed that, fourteen compounds were identified by chromatography-mass spectrometry analysis (GC- MS analysis). Propolis ethanolic extract inhibited the growth of six from the tested microorganisms including bacteria and fungi at 5 mg/ml against E. coli and B. subtilis and 20 mg/ml against S. aureus, P. aeruginosa, Penicillium italicum and Candida albicans, while it has no effect on A. fumigatus and Syncephalstrum racemasum. In experimental animals, Leucocytic counts and platelets, in addition, AST, ALT, CK and LDH were significantly increased, meanwhile, triiodothyronine (T3) and thyroxine (T4) level was decreased in CCl4 treated rats (group 3) compared to the control (group 1). Protection with ethanolic extract of propolis to rats received CCl4 (group 4) ameliorated the altered levels of studied parameters as compared to control group. In conclusion, these results suggest that propolis has antimicrobial activity and a protective effect on biological damages induced by carbon tetrachloride in rats. More researches are required to isolate and purify the active principle involve in biological activity of propolis to used as a curative agent

  3. Genetic Protective Role of D-Glucan against Oxidative Stress Induced by Mitomycin and Gamma-Radiation Exposure in Male Albino Rats

    International Nuclear Information System (INIS)

    D-glucan is a polysaccharide with multi-branching molecules derived from the cell wall of baker's yeast. It was reported to modulated innate immunity via interaction with membrane receptors on macrophages, neutrophils and natural killer cells and posses potent antioxidant and free radical scavenging capabilities. The aim of the present study was to investigate chemo-protective and radio-protective effect of D-glucan. Rats were orally (gavages) injected with D-glucan at dose of (20 mg/kg body wt) daily for three weeks. Mitomycin c (MMC) was administered three equal doses (1.5 mg/ kg) day after day for one week (2nd week) before radiation exposure at 3 fractionated doses (2 Gy) day after day in the 2nd week. The investigation were carried out on the days 3 and 10 post radiation-exposure and MMC administration for the determination of bone marrow micronucleus (Mn) frequency and DNA fragmentation in blood lymphocytes. The results showed that the exposure of animals to MMC and/ or irradiation led to clearly defined DNA fragmentation. D-glucan administration resulted in a significant improvement in lymphocytes DNA fragmentation and amelioration of Mn frequencies at day 3 and more pronounced at day 10 post irradiation. This study indicates that D-glucan has radio and chemo-protective effects against oxidative stress as a result of ?-radiation and/ or MMC exposure. So, D-glucan may be used to reduce the genotoxicity effects of different anticancer drugs and to reduce their unwanted side effects.

    Full Text Available Purpose: To determine the biochemical effects of energy drink alone or in combination with alcohol in normal albino rats. Methods: Twenty male albino rats weighing 160-180g were assigned into groups A-E of four rats per group. Group A and B rats were given low and high doses of ED, respectively, groups C and D were administered low and high doses of EDmA, respectively while group E rats were given distilled water and served as control. The treatment lasted for 30 days after which the animals were killed and their blood collected for laboratory analyses using standard methods. Results: There were no significant differences in body weight, packed cell volume and haemoglobin concentration with either administration of ED or EDmA in comparison to the control. Energy drink alone or EDmA has significant effects on total white blood cell count, plasma potassium, calcium, renal functions, liver enzymes and plasma triglycerides, with EDmA having more effects than ED alone, except for body weight where the energy drink alone has higher effect. Conclusion: Consumption of energy drink alone or in combination with alcohol is associated with significant alterations in some biochemical parameters. Caution should be exercised while consuming either of them. Public health education is urgently needed to correct the wrong impression already formed by the unsuspecting consumers, especially the youths.

    Full Text Available Background: Leucas Aspera is used in traditional medicine for many ailments. The present study was designed to evaluate the neuro behavioural effects in Wistar albino rats after oral administration of leaves of Leucas Aspera for 28 days. Methods: Wistar albino rats of either sex were treated with the aqueous suspension of dried powdered leaves of L. aspera. Three different groups of animals received L. aspera suspension in doses of 50 mg/kg/day, 100 mg /kg/day or 200mg/kg/day orally for 28 days. The animals were weighed once in a week and the food and water consumption was monitored every day. Behavioural changes in these animals were monitored every week using Rotarod, Actophotometer and William?s maze. Results: A significant increase in body weight, food and water consumption in rats could be recorded after 3rdand 4th week of treatment with 200mg/kg/day L. aspera. However, there were no changes in any of the behavioural responses in L. aspera treated groups compared to control. Conclusions: The unaltered neuro behavioural responses after L. aspera treatment indicate the safe nature of this medicinal plant. The significant increase in food consumption and body weight changes suggest a potential anabolic/ nutraceutical property of L aspera.. [Int J Basic Clin Pharmacol 2013; 2(4.000: 433-437

    This study was aimed at investigating the chronic effect of the artificial sweetener aspartame on oxidative stress in brain regions of Wistar strain albino rats. Many controversial reports are available on the use of aspartame as it releases methanol as one of its metabolite during metabolism. The present study proposed to investigate whether chronic aspartame (75 mg/kg) administration could release methanol and induce oxidative stress in the rat brain. To mimic the human methanol metabolism, methotrexate (MTX)-treated rats were included to study the aspartame effects. Wistar strain male albino rats were administered with aspartame orally and studied along with controls and MTX-treated controls. The blood methanol level was estimated, the animal was sacrificed and the free radical changes were observed in brain discrete regions by assessing the scavenging enzymes, reduced glutathione, lipid peroxidation (LPO) and protein thiol levels. It was observed that there was a significant increase in LPO levels, superoxide dismutase (SOD) activity, GPx levels and CAT activity with a significant decrease in GSH and protein thiol. Moreover, the increases in some of these enzymes were region specific. Chronic exposure of aspartame resulted in detectable methanol in blood. Methanol per se and its metabolites may be responsible for the generation of oxidative stress in brain regions.

    2011-01-01

    Full Text Available Artemisinin drugs were active during the intra-erythrocytic stage of malaria parasite infection. The activity of artemisinin and synthetic endoperoxides was related to their interaction with heme. The electrophillic intermediate formed from artemisinin in the presence of heme alkylates the protein portion of hemoglobin preferentially to the heme portion. Problem statement: Since there might be an interaction between artemisinin and the heme of the blood, we studied the effects of 5-day and 7-day oral Dihydroartemisinin (DHA treatments with 5 dosage regimens of dihydroartemisinin on the blood and six vital organs of Wistar albino rats. Approach: The dosages of DHA tested on 5 test adult Wistar albino rats (weight = 106-140 grams were 1, 2, 60 or 80 mg Kg-1 rat weight of DHA by oral intubation for 5 or 7 days. Four rats of similar weight which served as controls in each experiment were given distilled water equivalents of the administered doses of DHA. Another group of 5 test rats and four control rats (weight 75-90 gms were given 1 mg kg-1 rat weight of DHA or distilled water for 5 or 7 days and were allowed to rest for one week after which the treatment was repeated. Results: The findings of the study showed that Dihydroartemisinin (DHA had erythropoietin-like properties. In the study DHA produced dose, repetition and time dependent statistically significant increases in the Packed Cell Volume (PCV (PConclusion: This result suggested that the administered DHA inhibited its own stimulated statistically significant increases in the PCV and the WBC of the treated rats through an inhibitory (negative feed-back effect. The structure and composition of the blood cell types like the presence of large numbers of reticlocytes and left-shifted neutrophils in the blood samples of 5-day DHA -treated rats but not in those of 7-day DHA treated rats indicated that new haemopoiesis was actively going on in the first 5 days of DHA treatment but had slowed down by the sixth and seventh day of treatment. The initial stimulation of haemopoiesis and later inhibition of haemopoesis by a negative feed-back effect on haemopoiesis suggest that DHA has erythropoietin-like properties.

    Possible role of desferrioxamine (Dfx) against histopathological damages induced by ?-rays is evaluated.Male albino rats were divided into 4 groups. 1st group control animals, 2nd group: animals were exposed to whole body ?-irradiation (6 Gy), 3rd group: animals received intra peritoneal (I.P.) injections of Dfx for one week (250 mg/kg body wt) and 4th group: animals received Dfx one week before irradiation. The animals were investigated after 1, 7 and 21 days from irradiation.The results obtained revealed that exposure to ionizing-radiation caused histopathological disorders in liver tissues manifested as degeneration and vaculation of hepatocytes, pyknosis of nuclei, hepatocytes and congestion and dilation of blood sinusoids after 1, 7 and 21 days of irradiation.On the other hand, Dfx protected rats showed reduction in the histopathological changes produced by ?-irradiation.Thus, it could be concluded that Dfx might provide protection against radiation that induced histopathological damage in liver.

    The effect of carbon sulfide was studied on sexually matured male and female albino rats, subjected to 180-day exposure with concentrations 0.03, 50 and 200 mg/m3, 6 hours daily, 5 days a week. Carbon sulfide effect was studied by indices, characterizing the state of the oxidation processes and lipid metabolism. CS2--50 and 200 mg/m3 were established to inhibit oxygen consumption of liver homogenates better manifested in female animals, whereas in homogenates of testicles the tissue respiration was significantly inhibited only with 200 mg/m3. Some sexual discrepancies were observed in the indices of lipid metabolism, significantly changed with a concentration of 200 mg/m3. More susceptible in male animals proved to be the level of free fatty acids and total cholesterin, whereas in females--liver phospholipids in all cases were lower than the control group.

  2. Effect of melatonin on serum glucose and body weights in streptozotocin induced diabetes in albino rats

    International Nuclear Information System (INIS)

    It has been demonstrated in experimental animal models that oxidative stress causes persistent and chronic hyperglycaemia, causing reduction in antioxidant defence system, ultimately leading to accumulation of free radicals.This study was performed to observe the effect of melatonin on serum glucose and body weights in streptozotocin induced diabetes in albino rats. Methods: Forty healthy adult male albino rats were included in the study and divided equally into 4 groups for 6 weeks. Group-A was taken as control. Group-B received streptozotocin I/P in a dose of 37 mg/kg body weight. Group-C received 10 mg/100 ml melatonin in drinking water and Group-D received only melatonin. Results: Streptozotocin significantly increased serum glucose and decreased weight in group B animals, whereas in group C, melatonin significantly restored serum glucose but could not restore the body weights reduced by streptozotocin. There was a significant reduction in body weight in melatonin treated group D animals. Conclusion: Melatonin decreases oxidative stress and hyperglycemia, but cannot restore the body weight reduced by streptozotocin. In fact, it further reduces body weight both in diabetic and normal state. (author)

  3. Effects of Junk Foods on Brain Neurotransmitters (Dopamine and Serotonin) and some Biochemical Parameters in Albino Rats

    International Nuclear Information System (INIS)

    Nutritional Habits have changed significantly and junk foods have become widely popular, in recent years. The present study aimed to shed the light on the effect of potato chips and / or ketchup consumption on some biochemical parameters. Sixty four male and female albino rats were used in the study. Animals were maintained on 0.25 g potato chips/ rat and / or 0.125 g ketchup / rat, 5 days a week for 4 weeks. Potato chips showed the lowest body wt gain in the male rats after 4 weeks but, ketchup modulated this negative effect of the potato chips in the group of male animals fed on potato chips plus ketchup. Potato chips significantly decreased brain serotonin, liver glutathione (GSH) and catalase (CAT) in both sexes; brain dopamine, serum total proteins, albumin, total globulins, ?2- and ?1-globulins in the females and serum thyroxine (T4) in the male rats. Ketchup apparently affected serum T4 and A / G ratio in both sexes, brain dopamine and liver GSH in the males in addition to brain serotonin, serum total globulins and ?1-globulin in the female rats. Potato chips plus ketchup significantly changed T4, dopamine, GSH, CAT, ?1 and ?2-globulins in both sexes; serotonin and ?1-globulin in the male rats, total proteins and albumin in the females. It could be concluded that potato chips consumption might induce numerous adverse effects in various body organs

  5. Micronuclei frequency in albino rats exposed to high natural radiation

    International Nuclear Information System (INIS)

    Genotoxicity and DNA damage endpoints are used to evaluate results in the context of cell survival. Genotoxicity in mammalian cells is monitored mostly by using cytokinesis-block micronucleus (CBMN) assay. The score of micronuclei (MN) in peripheral blood lymphocytes can be used as a biomarker and also as a bio-dosimeter of radiation exposure. In the present study the effect of natural radiation on albino rats has been investigated, to find out if there is any increase in MN frequency in peripheral blood lymphocytes. Animals at the age of 2-3 weeks were exposed to natural radiation, at the dose of 10.38 ?Gyh-1 for a period of 6 months. A parallel control set was also maintained (0.12 ?Gy h-1'). Blood samples were collected from both test (exposed to natural radiation) and control rats. Lymphocyte culture was done following 'microculture techniques' for 72 h. Cytochalasin B, at a concentration of 6.0 ?g/ml, was added to the lymphocyte cultures at 44 h to block cytokinesis. The frequency of MN was evaluated by scoring a total of 1000 binucleated (BN) cells from one slide. The frequency of MN among the rats exposed to natural radiation was found to be 1.83±0.05 per 1000 BN cells and in the control it was 1.82±0.07 per 1000 BN cells. No statistically significant difference in the MN frequencies of exposed and control groups (p>0.05) was seen. The lower MN frequency in natural radiation exposed rats could be an indication of adaptive response. (author)

    In the present investigation, we attempted to study the modulation of morphological changes of endometrial surface epithelium by Scanning Electron Microscope (SCEM) in the adult albino rat after oral administration of roots extract. The origin of this experiment lies in the fact that the dry powdered roots of five plants, i.e., Plumbago rosea, Borassus flabellifer, Carica papaya (male), Dolichos lablab, and Shorea robusta in mixed form, has been traditionally used by the folk women of this region through oral route during the first seven days of a menstrual cycle to prevent conception. Ethanolic crude extract of these roots in composite form which has been referred to here as composite root extract (CRE) was administered to the adult female albino rat in a dose of 1000 mg/kg body weight/day through oral route continuously for 12 days starting from proestrous. The observations under SCEM showed that administration of the CRE induced morphological changes of the endometrial surface epithelium in albino rat uterus. The characteristic smooth regular pattern of normal epithelium appears to have been changed at places by haphazardly oriented groups of cells and loss of microvilli indicating a disorganized picture. This structural disparity has been thought to affect the smooth functioning of nidatory preparation in the endometrium. PMID:11024229

  8. Possible Protective Effect Of Quercetin Against 1,4-Dioxane And Gamma Radiation Induced Oxidative Stress In Male Albino Rats Key words: Quercetin, 1,4-Dioxane, Irradiated rats

    International Nuclear Information System (INIS)

    Quercetin, a bioflavonoid, is frequently found in consumed foods including apples, berries, onion, tea and vegetables. Quercetin has many beneficial effects on human health including cardiovascular protection, anti-cancer activity, cataract prevention, anti-viral activity and anti inflammatory effects. The present study is an attempt to evaluate the radio-protective properties of quercetin in gamma irradiated rat and the toxic effect of administration of 1,4-dioxane as well as the efficacy of quercetin as one of the most important antioxidant flavonoid in diet. At the 3rd and 10th days after the last dose of dioxane injection (one month) and radiation exposure (6 Gy, fractionated), the biochemical analysis in the serum showed significant elevation in lipid peroxide content (MDA), gamma glutamyl transferase (GGT), lactate dehydrogenase (LDH) and alpha fetoprotein (AFP) accompanied by significant depletion in glutathione (GSH). Also, the results showed significant increase in the level of DNA fragmentation in liver tissues of rats. Supplementation of quercetin to rats before and during exposure to gamma radiation and/or administration of 1,4-dioxane induced significant amelioration in the levels of all studied parameters. According to the results obtained, it could be concluded that quercetin might provide a protection against oxidative stress and metabolic disorders induced by gamma irradiation and 1,4-dioxane.

    Full Text Available The present study aimed to clarify the antidiabetic activity of Commiphora myrrha (CM aqueous extract on thirty adult male albino rats, which were divided into two groups; the first served as a control group, the second was injected with alloxan (120mg/Kg body weight and divided into two subgroups the first served as diabetic group, the second treated with (CM water extract (0.05mg/100 gm bwt. After 30 days of the treatment half of each group was sacrificed and the other half was left for other 15 days without any additional treatment (recovery period. Our results revealed highly significant decrease (p< 0.01 in blood glucose level and highly significant increase in body weight of the diabetic rats with different histological changes in cells of islets of Langerhans. These histological and physiological changes were ameliorated in rats treated with CM. Water extract of CM has a definite hypoglycemic, hyperinsulinimic effect, on the other hand, a significant increase in body weight, cell number and liver glycogen contents were achieved. The results of the present study clarify the role of CM as an active antidiabetic plant and suggest a relationship between drenching CM extract and insulin production. Other of investigations want be done to detect effects of different doses and time intervals of CM in diabetic animals.

  11. Effectiveness of grape seed extract on gamma radiation-induced hazards in albino rats

    International Nuclear Information System (INIS)

    The present study was designed to determine the possible protective effect of grape seed extract (GSE), rich in proanthocyanidins against gamma radiation-induced oxidative stress associated to serum metabolic disorders in the liver, heart and pancreas tissues of rats. Male albino rats received GSE (100 mg/day/Kg body weight), by gavages, for 14 successive days before whole body exposure to 5 Gy gamma radiation (shot dose). Animals were sacrificed 1, 14, and 28 days post radiation exposure. The results showed that in the irradiated group, tissues superoxide dismutase (SOD), catalase (CAT), glutathione peroxidase (GSH-Px) activities were decreased significantly, while thiobarbituric acid reactive substances (TBARS) content was increased, which was in parallel with significant increases in the activity of serum lactate dehydrogenase (LDH), creatine phosphokinase (CPK), aspartate and alanine aminotransferase (AST and ALT). Hyperglycemia, hyperinsulinaemia, hyperlipidaemia, decreases in red blood cells count (RBCs) count and hemoglobin (Hb) content were also observed in irradiated rats. n the GSE-treated irradiated group, significant increases of SOD, CAT, and GSH-Px activities with significant reduction of TBARS levels were observed in cardiac, liver, and pancreas tissues, in parallel to significant decreases in the activity of serum LDH, CPK, AST, and ALT compared with their corresponding values in the irradiated group. Moreover, serum glucose and insulin contents, RBCs count and Hb content were significantly improved in the GSE-treated irradiated rats. Furthermore, the marked increase in serum triglycerides and total cholesterol observed in irradiated rats, along with elevated LDL-C and decreased HDL-C levels were significantly improved in GSE treated rats. In conclusion, the present data demonstrate that GSE through its free radical scavenging and antioxidant properties attenuates ionizing radiation-induced oxidative injury suggesting that it may be a potential dietary supplement to minimize the side effects of radiotherapy

    The authors study the possibility of correcting cellular manifestations of disadaptation following chronic exposure to cold stress by means of preparations of Sch. chinensis. The model of chronic stress was cooling male albino rats daily for 1.5 h to a temperature of 28-30 C for 28 days. Since differences between levels of proliferation in intact animals and in the rats receiving 1.9% ethanol solution were absent, values obtained in the group of intact animals are presented in a table as the control. The animals underwent euthanasia 48 hours after the final exposure to the cold. The rats received an injection of tritium-thymidine one hour before sacrifice. It is shown that the results confirm those in previous studies of stimulation of DNA synthesis and mitotic activity in the corneal and lingual epithelium of albino rats during chronic exposure to stress

    Full Text Available The objective of the study was to determine lipid lowering efficacy of Pennisetum (P glaucum (Pearl millet, locally known as bajra, bran in hyperlipidemia albino rats. Simvastatin, (Tablet survive®, was used as cholesterol lowering synthetic drug. The period of 0-15 days was considered as a lead-in period to induce hyperlipidemia with atherogenic diet in albino rats. P. glaucum bran at dose rate of 2, 4 and 6 g/kg BW showed lipid lowering efficacy in hyperlipidemic rats at post-treatment days 30, 45 and 60. At the level of 6 g/kg, P. glaucum bran was able to produce a significant (P<0.05 increase in HDL- cholesterol (47% and fall in other lipid profile parameters i.e. total lipids (41%, triglycerides(48%, total cholesterol (39% and LDL- cholesterol (55%. P. glaucum 6 g/kg also reduced total cholesterol in liver tissue and increased fecal bile acid secretion. The results of present study suggest that 6 g/kg P. glaucum bran and 0.6 mg/kg Simvastatin were equally effective in treating hyperlipidemia in albino rats. Moreover, the potency of P. glaucum for stimulating fecal bile acid secretion in albino rats may safely be conceived, at least, as a part of mechanisms for its antihyperlipidemic efficacy.

    Full Text Available The contamination of water by metal compounds is a worldwide environmental problem. Concentration of metals is widely related to biochemical values, which are used in diseases diagnosis due to environmental toxicity. The sub-chronic combined effects of nickel and cobalt on body weight gain and biochemical parameters were determined and compared with those of Ni (2+ or Co (2+ alone in 6 weeks male albino (Wistar rats. Animals were given drinking solutions of NiSO4 6H2O [Ni (II cation, LD50/2] or CoSO4 6H2O [Co (II cation, LD50/2]. For the combined treatment (Ni + Co, the rats received both Ni (II cation (LD 50/2 and CO (II cation (LD50/2. Nickel and cobalt treatment decreased body weight gain. The nickel sulphate increased also the glucose level. The two heavy elements produced hepatic and renal damage, characterized by increased activity of alanine and aspartate transaminases (GPT, GOT and alkaline phosphatase. However lactate dehydrogenase activity (LDH was decreased. In addition, serum urea, serum creatinine, serum total protein and serum bilurebin concentrations were significantly elevated. In general the combined effect of Ni-Co was slightly less toxic than nickel or cobalt alone, suggesting antagonism between these toxicants.

    International Nuclear Information System (INIS)

    Beta-carotene is a group of plant compounds called carotenoids. It is a precursor for vitamin A and an important antioxidant. This study aimed to evaluate the radioprotective efficacy of ?-carotene against gamma radiation induced disorders in the testis of male albino rats, it included 4 groups: control group, treated group; animals of this group received a daily oral dose of ?-carotene (30 mg/kg body wt) for 1 week, irradiated group; animals of this group were subjected to whole body gamma irradiation at a dose level of 6 Gy, and treated-irradiated group; animals received a daily oral dose of ?-carotene (30 mg/ kg body wt) for 1 week before exposure to whole body gamma irradiation at a dose level of 6 Gy. 6 animals of each group were autopsied at 1, 3 and 5 days after ?-carotene treatment and/ or irradiation. All animals were subjected to the following investigations: acid phosphatase, alkaline phosphatase, glutathione and glutathione peroxidase in testis homogenate. In irradiated animals there was a highly significant decrease in testis alkaline phosphatase, glutathione and glutathione peroxidase activity. On the other hand, significant increase in acid phosphatase activity was observed. Treatment with ?-carotene before irradiation causes significant increase in alkaline phosphatase, glutathione and glutathione peroxidase activity and significant decrease in acid phosphatase activity compared to the irradiated group. The results of the present study indicated that ?-carotene ameliorated oxidative stress and the loss of cellular antioxidants and suggest that ?-carotene may reduce the radiation damage in testis of male albino rats

    Full Text Available Background: Treatment of cancers with cytotoxic agents such as tyrosine kinase inhibiting drugs often, but not always, result in transient to permanent testicular dysfunction. Germ cells are important targets of many chemicals. Most of the drugs are genotoxins and induce irreversible effect on genetic makeup. These mutagenic changes are proportionally related to carcinogenesis. This is alarmingly dangerous in youth and children, since these effects last longer, affecting fertility or forming basis for carcinogenesis. There is paucity of reports on planned studies of imatinib on the testicular function. Hence, the study was planned to assess the effects of imatinib on biochemical markers of testicular functions in male Swiss albino mice. Materials and Methods: Male Swiss albino mice were treated with imatinib and sacrificed at the end of first, second, fourth, fifth, seventh, and tenth week after the last exposure to imatinib. The testis were removed, weighed, and processed for biochemical analysis. Results: The intratesticular testosterone level was significantly (P<0.001 reduced in treated groups and severe effect was observed on week 4 and 5. The intratesticular lactate dehydrogenase (LDH level was significantly increased by imatinib in all treated groups up to week 5. Conclusion: Imatinib does affect testosterone and LDH level significantly, but this effect is reversible once the drug is withdrawn. This finding may help the clinicians to plan and address the fertility-related issues in young patients of reproductive age who are being treated with imatinib for gastrointestinal tumors and chronic myeloid leukemia.

    Full Text Available Background & objectives: Trypanosomiasis has remained a major set-back in the development oflivestock farming in tropical Africa. Thus the need for ascertaining the trypanotolerant levels ofdomestic animal breeds and possible improvement on them cannot be over-emphasised.Methods: Level of trypanotolerance in animals was compared between sexes using albino mice infectedwith a Nigerian strain of Trypanosoma brucei brucei at a 50% mouse lethal dose (MLD50.Results: The male mice showed unrestrained parasite growth with a prepatent period (PP of two daysand a mean survival period (MSP of six days corresponding to a gradual decrease in packed cellvolume (PCV, body weight, diet response and white blood cells (WBC count to the time of death.Their female counterparts showed a PP of three days and MSP of ten days with a similar PCV gradientbut a refractory WBC count. There was no significant difference in the differential leucocytes countin both sexes. However, the eosinophils count was significantly higher in the infected animals. It wasfound that female albino mice exercised more parasite restraint than their male counterparts.Interpretation & conclusion: The result suggests that the female animals may be more trypanotoleranthence may be more useful in protein production in trypanosomiasis endemic areas. However, furtherresearch using large domestic breeds like goats and sheep may be required to confirm the hypothesis.

    Full Text Available The present study aimed to clarify antidiabetic activity of aqueous extract from Aloe vera on thirty adult male albino rats were divided into three groups, the first served as a control group, the second was injected with alloxan (120mg / kg B.wt. and served as diabetic group and the third was injected with alloxan and treated with Aloe vera water extract ( 0.5 ml / 100 g B.wt. . After thirty days of treatment half of each group were scarified and the other one were left for 15 days without any additional treatment as a recovery period . The results revealed highly significant decrease ( p> 0.01 in blood glucose, and highly significant increase in both liver glycogen content and serum insulin level in the diabetic group treated with aqueos extract of A. vera when compared with the diabetic untreated group. It seems, therefore that water extract of A. vera results in a definite hypoglycemic, hyperinsulinemic effect. On the other hand, a significant increase of body weight gain and liver glycogen content was achieved. The results of this study clarify the role of Aloe vera active as antidiabetic plant and suggest a relationship between drenching. A. vera extract and insulin production which needs further investigation

    An impaired wound healing is one of the major health related problem in diabetic and non-diabetic patients around the globe. The pathogenic bacteria play a predominant role in delayed wound healing, owing to interaction in the wound area. In our previous work we developed green chemistry mediated copper oxide nanoparticles using Ficus religiosa leaf extract. In the present study we make an attempt to evaluate the anti-bacterial, and wound healing activity of green synthesized copper oxide nanoparticles in male Wistar Albino rats. The agar well diffusion assay revealed copper oxide nanoparticles have substantial inhibition activity against human pathogenic strains such as Klebsiella pneumoniae, Shigella dysenteriae, Staphylococcus aureus, Salmonella typhimurium and Escherichia coli, which were responsible for delayed wound healing process. Furthermore, the analyses results of wound closure, histopathology and protein profiling confirmed that the F. religiosa leaf extract tailored copper oxide nanoparticles have enhanced wound healing activity in Wistar Albino rats.

    Full Text Available Some of slimming drugs had been withdrawn from markets so, the present study was conducted to follow the effect of three different anorexic drugs; on the haematological and physical parameters of adults albino rats. The used drugs differ in their nature, where the first one i.e., apple-lite is a fully natural substance, the 2nd one i.e., mirapront-N. is a chemical substance and the 3rd one i.e., tenuate is a synthetic foamy filler substance. Fourty adult male albino rats (130 20g were randomly divided into four groups, ten on each treated group and ten for the first group which conserved as control group. The 2nd group was treated daily with apple-lite (3.5mg/ 100g.b.wt, the 3rd group was treated daily with mirapro-N (0.14mg/100g.b.wt and the 4th group was treated daily with tenuate (0.1 mg/100g.b.wt. Haematological parameters (RBCs, WBCs count, haemoglobin content (Hb, hematocrit value (Hct%, mean cell volume (MCV, mean cell heamoglobin (MCH and mean cell heamoglobin concentration (MCHC were detected after 30 days of treatment and also after 15 days of the last treatment as a recovery period. Also, body weight, percent of organs weight/body weight, skin-fold thickness and some vital measurements i.e. heart beats, respiratory rate and rectal temperature were recorded after the same periods of treatment and recovery. Haematological studies revealed that RBCs count, total WBCs count, Hb and Hct values were significantly decreased in the three groups treated daily with anorexic drugs for 30 days. These changes aere also recorded after the recovery period except in apple-lite treated group which showed insignificant change in RBCs and Hb after the recovery period. The calculated mean cell haemoglobin concentration (MCHC recorded significant increase in apple-lite after treated and recovery periods, while non significant changes in MCHC were observed after mirapro-N and tenuate groups after treatment 30 daysfor 30 days but significant increase of MCHC was recorded after the recovery period of tenuate treated group. Skin-fold thickness of the three regions tested (gluteal, back and belly revealed significant decrease in all the treated groups except the belly region in apple-lite treated group which showed insignificant decrease after treatment for 30 days. Significant decrease of skin-fold thickness of different regions still present after the recovery period of 15 days in the three treated groups except the back region of mirapro-N and the belly region of apple-lite- treated rats which showed insignificant decrease. Percent of organs weight/body weight were affected according the type of tested drug, while apple-lite- caused non significant changes, mirapro-N caused significant increase in hepatosomatic ratio and cardiosomatic ratio, and significant decrease in gonadosomatic ratio. On the other hand, tenuate resulted in a significant increase in percentage weight of kidneys and hepatosomatic ratio and significant decrease of gonadosomatic ratio after treatment for 30 days. After the recovery period, apple-lite revealed significant decrease in brain/b.wt. ratio, while mirapro-N still affected kidneys, gonadosomatic ratio and brain and tenuate still affected gonadosomatic ratio and brain; they recorded significant decrease. The physical measurement of vital signs, i.e. heart rate, respiratory rate and rectal temperature recorded insignificant change after treatment with apple-lite, mirapro-N and tenuate for 30 days, but significant increase of rectal temperature was recorded in the tenuate group of the treated rats. After recovery period insignificant changes in heart rate, respiratory rate and rectal temperature of the treated rats were observed in the three treated groups.

    Full Text Available The leaves of Enicostemma littorale blume (Ens and Eclipta alba (Ecl have been used for skin infection, antiviral and antibacterial activity in traditional medicine. The present study is aimed at to evaluate the hepato-protective effect of the aqueous leaf extracts of the above two plants during ethanol induced oxidative stress in albino rats. The aqueous leaf extracts of Enicostemma littorale and Eclipta alba combine (1:1 at dose level of 250 mg kg-1 b.wt. were tested for hepato-protective and antioxidant effects during ethanol induced oxidative stress in liver tissue of wistar male albino rats. The degree of hepatoprotection was assessed by measuring the activity levels of the marker enzymes such as serum aspartate transaminase (AST, alanine transaminase (ALT and alkaline phosphatase (ALP. Free radicals generated lipid peroxidation was assessed by measuring the tissue levels of thiobarbituric acid reacting substances (TBARS and the activity levels of the tissue antioxidant enzymes such as catalase (CAT, superoxide dismutase (SOD. The ethanol supplemented rats recorded elevated activity levels of serum AST, ALT and ALP revealing ethanol induced hepatotoxicity. The increased levels of TBARS in liver and decreased activity levels of SOD and CAT in ethanol fed animal’s revealed oxidative stress. The aqueous leaf extracts supplementation of Ens+Ecl in 1:1 produced significant hepatoprotection and antioxidative effect during ethanol induced hepatotoxicity. The study can be concluded that the therapeutic effect of aqueous leaf extracts of Ens+Ecl in 1:1 is not only hepatoprotective but also possess significant antioxidant property.

  7. Role Of Thymus Vulgaris And/Or Origanum Majorana L. Extract In Ameliorating The Toxicity Induced By 2-Amino-1-Methyl-6-Phenyl imidazo (4,5-b)Pyridine (PHIP) In Adult Male Albino Rats

    International Nuclear Information System (INIS)

    The present study was conducted to investigate the protective and therapeutic effect of the watery extract of Thymus vulgaris (thyme) and Origanum majorana L. (marjoram) or their mixture on the toxicity induced by 2-amino-1-methyl-6-phenyl imidazo(4,5-b)pyridine (PhIP) which is one of the most abundant toxic heterocyclic amines (HCA) in cooked meat. Oral administration of PhIP (75 ml/kg) twice a week for four weeks resulted in a significant increase in liver function (AST, ALT and ALP) with a percentage change recording 33.79% , 70.96% and 127.64%, respectively, accompanied with decrease in total protein content. Significant increase (P<0.05) was observed in both creatinine (45.33%) and blood urea (109.17%), whereas serum T3 and T4 recorded significant decrease with a percentage change of -57.32% and -42.44%, respectively. A marked significant reduction (P<0.05) in monoamine contents (DA and NE) in total brain was observed after the ingestion of PhIP recording -13.23% and -13.47%, respectively, as percentage change from control. The daily oral administration of thyme, marjoram and their mixture (W/W) in dose of 500 mg/kg alone, before or after PhIP administration caused a decrease in ALT, AST and ALP levels and increase in total protein in serum and also cause decrease in serum creatinine and urea. Non-significant changes in T3 and T4 levels were observed in rats received the herbal extract. On the other hand, the herbal extract improved T3 and T4 levels before and after PhIP treatment bringing the hormonal levels near to that of control. Moreover, rats that received pre and post treatment with thyme, marjoram and their mixture (W/W) after being treated with PhIP showed high significant reduction in the elevated levels of DA and NE produced by PhIP treatment. From the current investigation, it could be concluded that the watery extract polyphenol flavonoids of thyme and marjoram has the protective and therapeutic effect on the toxicity produced by heterocyclic amine (PhIP) which may be due to their antioxidant property and free radical scavengers activity

The rest of groups were affected by induction of experimental diabetes by subcutaneous injection of Alloxan. The second group consisted of diabetic rats without any treatment. The third group was treated by the aqueous extract of mixture contains Foenugreek, Nigella and Termis seeds. The fourth group was treated with the aqueous extract of Nigella sativa seeds, while the fifth group was treated with the aqueous extract of Foenugreek seeds.The sixth one was treated with the aqueous extract of Termis seeds with the administered dose of the plant extracts (100 mg/kg body weight.After four weeks of treatment, different biochemical parameters were performed including estimation of blood sugar level and serum insulin level. Pancreatic and liver samples were obtained and processed for microscopic and quantitative evaluation after staining the prepared sections with both heamatoxylin and eosin as well as a special stain for demonstration of the different pancreatic cells in the Islet of Langerhans. Results: The usage of the mixture or each plant alone corrected the glucose level and insulin level. Microscopically there was definite decrease in the number and diameter of beta pancreatic cells in the diabetic group, while the other pancreatic cells were not affected (alpha and delta cells. The use of medicinal plants in the different groups of this study greatly improved such cellular changes and the level of blood sugar level was corrected. The present results showed that the activity of the mixture was the best when compared with Nigella, Foenugreek and Termis seeds. Conclusions: The water extract of the mixture is the most powerful in amelioration hyperglycemia and most of all damage effects of Alloxan on the liver and texture, hematological parameters, and lipid profile. So it is advised to use the plant mixture as an antidiabetic agent rather than the use of each plant separately. Repeating such study with the use of variable doses may be helpful in better evaluation for the required doses.

  9. Protective effect of zinc aspartate against acetaminophen induced hepato-renal toxicity in albino rats

    International Nuclear Information System (INIS)

    Zinc is an essential nutrient that is required in humans and animals for many physiological functions, including antioxidant functions. The evidence to date indicates that zinc is an important element that links antioxidant system and tissue damage. Acetaminophen (AP), a widely used analgesic and antipyretic, produces hepatocyte and renal tubular necrosis in human and animals following overdose. In human, AP is one of the most common causes of acute liver failure as a result of accidental or deliberate overdose. Moreover, the initial event in AP toxicity is a toxic metabolic injury with the release of free radicals and subsequent cellular death by necrosis and apoptosis. This study was designed to evaluate the potential protective role of zinc aspartate in case of acetaminophen induced hepato-renal toxicity in rats. A total number of 32 adult male albino rats were divided into 4 equal groups: group I (control group), group II (zinc aspartate treated group), group III (acetaminophen treated group; by a single oral dose of 750 mg/kg body weight) and group IV acetaminophen plus zinc treated group; (zinc aspartate was intraperitoneally given one hour after acetaminophen administration in a dose of 30 mg/kg body weight). Serum levels of: alanine aminotransferase, aspartate aminotransferase, direct bilirubin, blood urea nitrogen, creatinine, uric acid, xanthine oxidase (XO), glutathione (GSH), malonaldehyde (MDA) and nitric oxide (NO) were assessed in all groups. The results of this study showed that treatment with acetaminophen alone (group III) produced a significant increase in serum levels of the liver enzymes and direct bilirubin. Moreover, in the same group there was a significant increase in the blood urea nitrogen and serum creatinine compared to the control group. In addition, there was a significant increase in XO and MDA and a significant decrease in GSH and NO level. Injection of rats with zinc aspartate after acetaminophen treatment could produce a significant protection against the toxic effect of acetaminophen, in comparison with that of acetaminophen treated group. In conclusion, biochemical evaluation revealed that zinc aspartate has a partial protective effect against acetaminophen induced hepato-renal toxicity and oxidative stress. Accordingly, zinc may be an effective therapeutic agent in prevention and treatment of acetaminophen hepatotoxicity, nephrotoxicity and free radical production

    Full Text Available The present study aimed to investigate the possible interference of cisplatin or carboplatin on oxidative enzymes in liver of albino rats. Rats were divided into three groups each consisting of eight animals. Group 1 (Control received 0.9% of normal saline. Group 2 (Treatment received cisplatin of 3 mg/kg body weight and Group 3 (Treatment received carboplatin of 10 mg/kg body weight. Injections were given intra-peritoneally to rats on 1st, 3rd and 5th day of experimentation. On 45th day of experiment, animals were sacrificed by cervical dislocation. Succinate dehydrogenases (SDH, Lactate dehydrogenase (LDH, Glucose-6-phosphate dehydrogenase (G-6-PDH activities in the cytosol fraction were assayed in liver of albino rats. Cisplatin or carboplatin treatment caused significant changes in activity levels of SDH, LDH & G-6-PDH in liver of experimental rats, when compared to control rats. From the study it may be concluded that, hepatic tissue is meeting its energy requirements through alternative pathways. In other words this can be viewed as functional or physiological adaptation of the liver in treated rats, may be due to stress caused by platinum-based anticancer drugs.

    Full Text Available Problem statement: Aluminum chloride (AlCl3 is commonly used in daily life but it can be potentially toxic. Therefore, the present study was carried out to investigate the protective effects of camel' milk against aluminum-induced biochemical alterations and oxidative stress in the liver and kidney of white albino rats. Approach: White albino male rats (230-250 g were divided into three groups of 10 rats: a control group treated with normal saline, the AlCl3-treated group and the camel's milk-AlCl3-treated group. The AlCl3 treated group received 0.5 mg kg-1 of AlCl3 orally. The camel's milk-AlCl3-treated group was fed 1 mL of fresh camel's milk 10 minutes prior to the administration of oral AlCl3. All rats were treated every day for 30 days. Liver and kidney biochemical serum parameters were analyzed. Lipid peroxidation, as determined by the tissue concentrations of thiobarbituric acid reactive substances (TBARS and hydrogen peroxide (HP, and the oxidative stress status, as measured by glutathione (GSH, superoxide dismutase (SOD and catalase (CAT activity, were evaluated in the kidney and liver of treated rats. Results: Data showed that the oral administration of AlCl3 resulted in statistically significant increases in the serum levels of urea, creatinine, bilirubin, aspartate aminotransferase (AST, alanine aminotransferase (ALT, alkaline phosphatase (ALP, lactate dehydrogenase (LDH, cholesterol and triglycerides; the total amount of protein and albumin were also significantly decreased. However, these parameters were within normal levels in the rats given camel's milk prior to AlCl3. Additionally, oral administration of AlCl3 induced lipid peroxidation in the liver and kidney, which was indicated by a significant increase in lipid peroxidation biomarkers (TBARS and HP and a significant decrease in the activities of GSH, SOD and CAT. In all rats treated with camel's milk before being given AlCl3, lipid peroxidation and oxidative stress parameters were within normal levels. Conclusion: Treatment with camel's milk prior to AlCl3 exposure alleviates AlCl3-associated hazards and protects the kidney and liver from AlCl3 toxicity.

    The purpose of this work was to evaluate the effect of aqueous extract of fenugreek seeds against hepatotoxicity induced in albino rats by the anticancer drug adriamycin (ADR). Animals were given single dose of ADR (10 mg/kg body weight) and were killed after 2 and 4 weeks. Liver of ADR-treated animals showed histopathological and biochemical alterations. The histopathological changes include hepatic tissue impairment, cytoplasmic vacuolization of the hepatocytes, congestion of blood vessels, leucocytic infiltrations and fatty infiltration. Moreover, the expression of proliferating cell nuclear antigen was increased in ADR-treated rats. The liver enzymes, aspartate aminotransferase (ALT) and alanine aminotransferase (AST) were increased in the sera of treated rats. Moreover, ADR significantly increased the concentration of malondialdehyde (MDA) and decreased the activities of superoxide dismutase (SOD) and catalase (CAT) in hepatic tissue. Treating animals with ADR and aqueous extract of fenugreek (0.4 g/kg body weight) seeds led to an improvement in histological and biochemical alterations induced by ADR. The biochemical results showed that AST and ALT appeared normal together with reduction in the level of MDA (lipid peroxidation marker) and increase in SOD and CAT activities. It was concluded from this study that the aqueous extract fenugreek seeds has a beneficial impact on ADR-induced hepatotoxicity due to its antioxidant effect in albino rats. PMID:22082829

    Full Text Available The study was carried out to ascertain the effect of a cassava based diet (gari on crude oil heamato-toxicity in albino rats by feeding diet contaminated with various concentrations of crude oil mixed with 20% gari to determine the protective effect of gari. The haematological parameters haemoglobin (Hb, Packed cell volume (PCV and white blood cell count (WBC(Total and differential were monitored in the animals. Gari feeding at 20% caused insignificant dose dependent decrease in Hb and PCV but significant dose dependent white blood cell count in gari fed albino rats compared with Petroleum fed albino rats (P<0.05. Dose dependent decrease in Hb, PCV and white blood cell count was also observed in petroleum fed rats compared with their controls (P<0.05.  The study showed that ingestion of petroleum contaminated diet caused decreased haemoglobin (Hb, Packed cell volume (PCV and white blood cell count, an indicator of possible blood damage but supplementation of the diet with 20% gari decreased the haemoglobin (Hb, Packed cell volume (PCV and white blood cell count observed in petroleum fed albino rats. This study showed that feeding on gari diet did not reverse the damage caused by crude petroleum as evidenced by insignificant differences in Hb and PCV concentrations possibly as result of cyanide present in the gari.Industrial relevanceCassava is a staple food in human diets in over 80 countries (Gomez, et al 1988. Gari a starchy food prepared from cassava (Manihot utilisima tubers is one of the most popular staple foods of the people of the rain forest belt of West Africa. Gari contains mainly starch-20% amylase and 70% amylopectin having lost the soluble carbohydrates. Crude petroleum is capable of eliciting haemolytic toxicity of the blood cells in conditions of long- exposure causing decrease haemoglobin, white cell count and PCV levels. The study was carried out to see the effect of gari, a staple food on haemolytic toxicity caused by crude petroleum.Keywords: Cassava; Gari; Petroleum; haemato-toxicity

  15. Protective role of ginkgo Biloba extract against gamma radiation and alcohol induced liver damage in albino rats

    International Nuclear Information System (INIS)

    Ginkgo biloba extract (EGb 761) is a standardized extract of Ginkgo biloba leaves that promotes vasodilatation and improves blood flow through arteries, veins and capillaries and has antioxidant properties as a tree radical scavenger. This study was designed to evaluate the protective efficacy of EGb 761 against gamma radiation and/ or alcohol induced disorders in the liver of male albino rats. EGb 761 was given orally at a dose level of 100 mg/ kg body wt for 4 days, absolute alcohol was administered orally at a dose level of 1ml/ rat for 4 days and the dose of gamma radiation was 6.5 Gy. All animals were subjected to the following investigations: nitric oxide (NO), superoxide dismutase (SOD), malonaldehyde (MDA). reduced glutathion (GSH) and glutathione peroxidase (GSHPx) in the liver tissue. In irradiated and/ or alcoholic animal groups, there was a highly significant decrease in liver NO and GSH content and in the activities of GSHPx and SOD. On the other hand, significant increase in MDA content was observed. Treatment with EGb 761 before irradiation and/or alcohol causes significant increase in NO and GSH content and in the activities of GSHPx and SOD and significant decrease in MDA content compared to the irradiated and/ or alcoholic groups. Based on these observations, one could conclude that pre-treatment of rats with EGb 761 could partly protect liver from gamma rays and/ or absolute alcohol injurious and this protection may be induced, at least partly, through antioxidant mechanisms

  16. Effect of methimazole-induced hypothyroidism on histological characteristics of parotid gland of albino rat

    International Nuclear Information System (INIS)

    Background: The current study was carried out to investigate the effect of hypothyroidism on the histological structure of parotid salivary gland of the rat. Methods: Twenty male albino rats, weighing between 130-150 grams, were used which were divided into two groups; control group (A) and an experimental group (B), each containing 10 animals. Group B was rendered hypothyroid by giving methimazole (MMI) as 0.02% solution in drinking water daily for 3 weeks. On day 22 parotid and thyroid glands were removed, weighed and processed for light microscopy. Salivary gland was fixed in Bouin's solution, H and E and Toluidine blue stains were used for histological examination. Serum T /sub 3/, T/sub 4/ and TSH levels were determined by enzyme immunoassay. Results: In group A, serum concentration of T/sub 3/, T/sub 4/ and TSH was 12.58+-3.05 mu g/ml, 4.72 +- 1.20 macro g/dl, and 0.25 +- 0.24 macro IU/ml respectively, where as in group B it was 2.14+-1.83 mu g/ml, 1.04 +- 0.44 macro g/dl and 1.44+-0.20 mu U/ml respectively. When differences between T/sub 3/, T/sub 4/ and TSH of the groups were compared, the p-value was <0.000, <0.000, and <0.000 respectively. Mean thyroid weight significantly increased in group B (44.1 0+-1.66 mg) when compared to that in group A (33.70+-1.56 mg). These findings established the occurrence of hypothyroid state in the experimental group. There was a statistically significant reduction in the parotid gland weight in the animals of the experimental group (38.30 +- 1.15 mg) when compared to the control group (39.60 +- 0.84 mg), (p<0.01). With light microscopy, group A showed a normal structure of parotid salivary gland, whereas multiple histological changes were observed in parotrid gland of the experimental group. Number of mast cells in parotid gland was also significantly higher (p<0.017) in group B (3.70 +- 1.11/mm/sup 2/) than in group A (2.25 +- 1.34/mm/sup 2/). Conclusion: The level of T/sub 3/ T/sub 4/ decreased and that of TSH increased in the experimental group when compared with control group; there were also changes in the histological structure of the parotid salivary gland.

    Full Text Available Background: Flunarizine is commonly used for migraine prophylaxis. It is a calcium channel blocker which blocks the L-type, T-type and N-type of calcium channels of pancreatic beta cells and other cells. It is believed to cause alterations in blood glucose levels secondary to its effect on calcium channel dependent insulin secretion.Objective: To evaluate the effect of flunarizine on blood glucose levels in normal albino rats through oral glucose tolerance test (OGTTMaterials and Methods: Flunarizine and distilled water were given orally for 5 days to the test (T and control (C groups of 6 normal albino rats respectively (N = 6. OGTT was conducted on both the groups on the 5th day and blood glucose levels were analyzed at 0, 60 and 150 minutes. Data was analyzed with one way ANOVA and independent samples t -test.Results: Flunarizine caused hyperglycemia at all durations of the OGTT with a maximum difference of 26% at 0 hour. The extent of worsening was maximum at 60 - 0 minute interval in both the instances i.e. test group value compared with control (T-C and control values compared with itself (C-C. The comparison of extent of hyperglycemia revealed that T-C showed 17% (47mg/dl more hyperglycemia than the C-C (40 mg/dl.Conclusion: Flunarizine has hyperglycemic effects in normal albino rats when given for 5 consecutive days orally even at the dose used for prophylaxis of migraine in human beings. A word of caution is thus advised when using flunarizine in impaired glucose tolerance or diabetic subjects.

  3. Caffeine and Aspirin Protecting Albino Rats A gainst Biochemical and Histological Disorders Induced by Whole Body Gamma Irradiation

    International Nuclear Information System (INIS)

    Caffeine is an alkaloid (purine derivative) that contains flavonoids, where as aspirin, natural component of mammalian tissue ( acetylsalicylic acid) is one of the most commonly used non steroidal anti - inflammatory , and it is a necessary factor in the utilization of long - chain fatty acids to produce energy. Furthermore, it has been shown to protect cells from per oxidative stress. Th e objective of the present study is to evaluate the efficacy of caffeine (1,3,7 - trimethyl xanthine) 80 mg/kg b.wt. a nd aspirin ( acetylsalicylic acid) in the amelioration of the physiological and histological changes in stomach and intestine of rats exposed to gamma irradiation . Male albino rats were divided into 8 groups. 1 - Control group: rats not subject to any treatment, 2 - Caffeine group: rats received caffeine ( 80 ml/Kg body weight )via intraperitoneal injection for 21 days, 3 - Aspirin group: rats received aspirin (150 mg / kg body) via intraperitoneal injection for 21 days , 4 - Caffeine + Aspirin group: rats received caffeine a nd aspirin treatment, 5 - Radiation groups: rats were whole body gamma irradiated at 8 Gy , 6 - Caffeine + Radiation group: rats received caffeine for 21 days before whole body gamma irradiation at 8 Gy, 7 - Aspirin + Radiation group: rats received aspirin during 21 days before w hole body gamma irradiation , 8 - Caffeine + Aspirin + Radiation group: rats received caffeine parallel to aspirin for 21 days before whole body gamma irradiation. Animals were sacrificed 24 hrs post irradiation. The results demonstrated that rats exposed to whole body gamma irradiation showed a significant increase in alanine amino transferase (AL ) , aspartate amino transferase ( AST), and alkaline phosphatase (ALP) activities, and a significant decrease in total protein indicating liver injury. A significant increase in urea, creatinine, Na+,and K+ were recorded indicating kidney damage. Alteration of liver and kidney functions was accompanied by a significant increase in the content of thiobarbituric acid reactive substances (TBARS) associated with a significant decrease in glutathione (GSH) content, superoxide dismutase (SOD), and catalase (CAT) activities indicating oxidative stress. In addition, radiation caused inflammatory, fibrotic and cellular damage to the intestine and stomach. A demonstration of caffeine and aspirin resulted in significant improvement in hepatic and renal functions associated with reduction in oxidative stress and amelioration of the histological changes caused by gamma irradiation. It could be concluded that the antioxidant properties of caffeine and aspirin might modulate ?-radiation-induced oxidative stress and histological disorders

  6. Effect of protein malnutrition on the metabolism of bone collagen in albino rats

    International Nuclear Information System (INIS)

    The effect of protein malnutrition on the metabolism of collagen in bone was studied in young female albino rats after a single injection of 3H-proline. Both specific and total radioactivities of hydroxyproline in the total collagen of the bone were found to decrease in the protein-deficient animals, indicating decreased rate of collagen synthesis. In the urine the amount of hydroxyproline excreted and total radioactivity of 3H-hydroxyproline were greatly decreased. The results of the present investigation therefore clearly indicate decreased synthesis and catabolism of collagen in bones of protein deficient animals compared to controls. (auth.)

    1999-12-27

    Fourier transform infrared (FT-IR) microspectroscopy is a powerful technique that can be used to collect infrared spectra from microscopic regions of tissue sections. The infrared spectra are evaluated to chemically characterize the absorbing molecules. This technique can be applied to normal or diseased tissues. In the latter case, FT-IR microspectroscopy can reveal chemical changes that are associated with discrete regions of lesion sites, which can provide insights into the chemical mechanisms of disease processes. In the present study, FT-IR microspectroscopy was used to analyze sections of retina from normal (pigmented) and albino rats. The outer segments of retinas from pigmented animals were found to have unusually strong absorption values for C&z.dbnd6;C-H unsaturation and carbonyl functional groups. Docosahexaenoic acid (DHA), a major constituent of lipids in the outer segments, also had particularly high absorption values for these functional groups, which suggests that it is responsible for those enhanced absorption values. Absorbance values for the unsaturation and carbonyl functional groups were substantially reduced in the outer segments of retinas from albino animals. This finding, together with data from other studies on light-induced oxidative events in the retina, indicates a loss of DHA by a light-induced mechanism in albino animals. The outer nuclear layer had strong absorbance values for H-C-OH and P&z. dbnd6;O functional groups, which is likely due to the sugar phosphate backbone of DNA. The outer and inner plexiform layers were found to contain greater concentrations of CH(2) and C&z.dbnd6;O functional groups than the outer and inner nuclear layers, which is due to the high concentration of synaptic connections in the former layers. In summary, FT-IR microspectroscopy revealed a unique chemical profile in the outer segments compared to other retinal layers, and this profile was altered in albino animals. PMID:10594378

  8. NEUROPHYSIOLOGICAL STUDY ON THE EFFECT OF ARTIFICIAL FOOD COLOUR AND SWEETENER IN ADULT MALE ALBINO MICE

    International Nuclear Information System (INIS)

    This study aims to investigate the effect of aspartame (artificial sweetener) and sunset yellow (artificial colour) on monoamines content in different brain areas of the adult male albino mice (cerebellum, brain stem, striatum, hypothalamus and cerebral cortex), and also on testosterone level in serum.The present study showed that the daily intraperitoneal injection of aspartame with dose of 200 mg/kg caused significant increase in monoamines content and testosterone level at most experimental periods. The elevation of monoamines content may be due to increase in phenylalanine concentration which leading to increase the synthesis of monoamines. The elevation of testosterone level may be due to the increment of DA content in hypothalamus which led to increase the release of LHRH. On the other hand, the daily intraperitoneal injection of sunset yellow with a dose of 2.5 mg/kg caused significant decrease in monoamines content and non-significant change in serum testosterone level at most experimental periods. The decrement in monoamines content may be due to the decrease in its uptake by the neurotransmitters or decrease in its synthesis

  9. Vitamin D3 May Ameliorate the Ketoconazole Induced Adrenal Injury: Histological and Immunohistochemical Studies on Albino Rats

    International Nuclear Information System (INIS)

    Ketoconazole (KZ) is used widely for treating the superficial, systemic fungal activities and hyperandrogenemic states. Its uses are limited by its deleterious effect on histological structure and function of the adrenal cortex. This study investigates whether vitamin D3 supplement can ameliorate the morphological changes induced by KZ. Thirty four adult male albino rats were randomized into control group (Group I) which was subdivided into: control 1 (n=7) and control 2 (n=7): In control 1, rats were intraperitoneal (I.P) injected once with 1 ml of polyethylene glycol-400 for 15 consecutive days and control 2 rats were injected I.P with (1 ?g/kg) of vitamin D3 for the same period. Group II (n=10): rats were I.P injected with KZ (10 mg/100 g of body weight) once daily for 15 days; Group III (n=10): rats were I.P concomitantly injected with KZ and vitamin D3 similar doses to animals in groups II and control 2 respectively. Blood samples were collected to determine plasma ACTH, corticosterone and aldosterone levels. The right adrenal specimens sections were stained with Haematoxylin & Eosin and Masson Trichrome for histological studies and treated with Bax, Ubiquitin and vitamin D receptors for immunohistochemical studies. KZ induced adrenal cortical morphological changes in forms of disturbed adrenocorticocyte cytological architecture, nuclear changes, and intracellular lipid accumulation. KZ also increased adrenal Bax and Ub but decreased the vitamin D receptors immunopositive staining expression, in addition to increased plasma ACTH as well as decreased corticosterone and aldosterone levels. These changes were ameliorated by supplementing with vitamin D3

    Full Text Available This study evaluates the effect of acute (24 h and subacute (3 weeks treatment of the Teucrium polium decoction on liver and kidney functions and hematological parameters in rats. The toxicity study with this decoction did not produce mortality. No marked adverse alterations were observed in hematological and biochemical parameters during acute toxicity. In the subacute toxicity studies, red blood cells counts, Hemoglobin (Hb and Packed Cell Volume (PVC insignificantly decreased. However, other blood indices, Mean Corpuscular Volume (MCV, Mean Corpuscular Hemoglobin (MCH and Mean Corpuscular Hemoglobin Concentration (MCHC were not changed. There was significant (p<0.001 increase in white blood cells. Serum glucose level change was insignificant, while the level of serum cholesterol and triglycerides were significantly (p<0.001 reduced. The Activity of Serum Transaminases (ALT and AST showed non significant changes, urea, uric acid and creatinine levels were found non significant changes. In conclusion the statistical analysis of our results indicates that treatment with T. polium did not cause any attension that might suggest the presence of pathological damage at the dose investigation.

    We have determined the incorporation of retinol-C14 into liver mitochondrial membranes and blood cell stroma in albino male Wistar strain rats, fed with a vitamin A deficient diet for 30, 60 and 90 days. At the end of the vitamin A deficient period, rats were kept fasting for 24 hours and then administered orally retinol-C14 (1,25 microC). They were divided into groups and killed after 3 hours, 3, 6, 12 days from the administration of retinol-C14. The incorporation is very high in one-month deficient rats, it decreases as the experimental period and the intervals after the administration of retinol-C14 grow longer. PMID:582873

  12. Dietary Antioxidants Effectiveness on Carbon Tetrachloride-Induced Hepatotoxicity in Adult Female Albino Rats

    International Nuclear Information System (INIS)

    Hepatic toxicity through carbon tetrachloride (CCI4) induced lipid peroxidation was extensively used in experimental models to understand the cellular mechanisms behind oxidative damage and to evaluate the therapeutic potential of drugs and dietary antioxidants. The ameliorative effect of Aloe vera juice and carrot supplementation on hepato carcinogenesis induced by carbon tetrachloride in adult female albino rats was investigated. The carcinogenic process was determined by measuring gamma-glutamyl transpeptidase (GGT), ornithine carbamyl transferase (OCT), thiobarbituric acid reactive substances (TBARs), representing levels of lipid peroxides, and carcinoembryonic antigen (CEA) in the sera of female albino rats. Carbon tetrachloride significantly elevated the serum GGT, OCT activities and the level of TBARs. Administration of Aloe vera leaf juice filtrate after CCl4 treatment resulted in a non-significant modification in GGT, OCT activities and significantly improved the level of TBARs in comparison with control. Supplementation of carrot to CCI4 treated animals led to a great amelioration in OCT activity and TBARs level, whereas GGT activity was ameliorated but statistically changed compared to control. There was a non-significant alteration in the level of CEA in all treated groups compared to normal control one

    Amiodarone is a potent antiarrhythmic drug that is used to treat ventricular and supraventricular tachyarrhythmias. The present work studied the effect of amiodarone on the kidney of albino rats and the possible ameliorative role of grapefruit juice. Administration of amiodarone by gastric intubation (18 mg/kg body weight (b.w.), daily for 5 weeks) caused many histological alterations including intertubular leucocytic infiltrations, degeneration of the renal tubules, and atrophy of the glomeruli. Amiodarone caused marked elevation in serum creatinine and blood urea nitrogen. Histochemical examination of the renal tubules revealed depletion of glycogen and total proteins. Besides, animals administered with amiodarone showed an increase of apoptotic bands as detected by gel electrophoresis. Treating animals with amiodarone and grapefruit juice (27 ml/kg b.w.) caused an improvement in histological and histochemical appearance of the kidney together with decrease of serum creatinine and blood urea nitrogen. Moreover, the apoptosis was decreased. It is concluded from the obtained results that grapefruit juice ameliorates the nephrotoxicity of amiodarone in albino rats and this may be due to the potent antioxidant effects of its components.

    Electrical stimulation of the sinoatrial node region of isolated atria in medium containing physostigmine (0.1 micrograms/ml) produces a negative chronotropic effect whose intensity and duration depend mainly on the amount of acetylcholine released from postganglionic parasympathetic fibres endings. This technique was used to study functional maturation of the given neurones during postnatal development of albino rats. Preparations from animals of different ages were stimulated with 2-second bursts of rectangular pulses (frequency 50 Hz, pulse duration 0.02 ms, voltage 22.5--27.5 V) and frequency changes of the preparation were registered by recording extracellular action potentials. At 10 days the negative chronotropic effect is very weak and at 15 days it is only slightly stronger, but at 18 days it is almost the same as in adult animals. At 24 and 34 days the reaction is somewhat stronger than in adulthood. It can be concluded from these observations that functional maturation of the postganglionic parasympathetic neurones innervating the sinoatrial node in albino rats occurs between the 10th and 20th day of postnatal life.

  15. Protective Effect Of Avocado Oil Against Biochemical And Histological Changes In Whole Body Gamma Irradiation In Albino Rats

    International Nuclear Information System (INIS)

    Avocado oil, extracted from the pulp of the fruit, is rich in poly-unsaturated fatty acids, linoleic, linolenic, oleic acids and the monounsaturated fatty acid. It also contains B-sitosterol, B-carotene, lecithin, minerals and vitamins A, C, D and E. Avocado oil lowers the blood levels of serum lipids and has antioxidant properties as a free radical scavenger. Male albino rats were divided into 5 groups. 1- Control group: rats not subjected to any treatment, 2- Avocado treated group: rats received avocado oil (0.1 ml/kg/day) via intraperitoneal injection during 21 days, 3- Irradiated group: rats were whole body gamma irradiated with 7 Gy, 4- Avocado + irradiated group: rats received avocado oil for 21 days then exposed to whole body gamma irradiation with 7 Gy and 5- Radiation + avocado group: rats were exposed to 7 Gy whole body gamma irradiation then received avocado oil for 21 days. Avocado oil (0.1 ml/kg/day) was given to rats, receiving a standard diet, for 21 days before exposure to 7 Gy whole body gamma irradiation then the treatment was continued for 10 days after irradiation. Several investigations were carried out such as superoxide dismutase (SOD), malondialdehyde (MDA), reduced glutathione (GSH), catalase (CAT), lipid profile and blood sugar. High significant increase in MDA was observed and treatment with avocado before irradiation caused significant increase in GSH, CAT and SOD and significant decrease in MDA as compared to the irradiated groups. The results also showed that treatment with avocado oil significantly diminished the radiation-induced alterations observed in the levels of lipid profile and glucose. The results demonstrated that whole body gamma irradiated rats showed significant increase in alanine aminotransferase (ALT), aspartate amino-transferase (AST), alkaline phosphatase (ALP) and glucose. By studying the lipid profile, significant increases in cholesterol, triglycerides and LDL-C levels were recorded while significant decrease was recorded in HDL-C. The significant increase in thiobarbituric acid reactive substances (TBARS) associated with significant decrease in glutathione (GSH), superoxide dismutase (SOD) and catalase (CAT) indicated oxidative stress. The administration of avocado oil resulted in significant improvement in hepatic function and lipid profile which associated with reduction in oxidative stress. The histological study showed that administration of avocado oil before irradiation led to partial improvement in hepatocytes and also preserved hepatic architecture while after irradiation, loss of architecture, fibrosis and fatty infiltration were observed. These results indicated that avocado oil can enhance the improvement of liver tissues in gamma irradiated rats. It could be concluded that avocado oil may have a bioprotective effect on radiation-induced oxidative stress and might modulate gamma radiation-induced hepatotoxicity possibly through its antioxidant properties

    Changes in the acetylcholine (ACh) content and concentration in the atrial tissue of albino rats between the third day of postnatal life and adulthood were studied. The ACh content (ng in whole atria) rose during the whole of the period in question, from 5.6 ng at 3--4 days to 307.5 ng in adult rats. The ACh concentration (micrograms/g fresh tissue) rose up to the 53rd day after birth, when it attained adult values. The fastest increase in both the ACh content and concentration was observed between the 10th and the 17th postnatal day, when it amounted to over 46% of the total concentration increase between the third day of life and adulthood.

    Full Text Available In recent years all over the world, medicinal plants are used quite a lot but side effects of biological and chemical contents and radiopharmaceutical interactions for each consumer in question aren't entirely well-known. The studies of plant origin drug interaction with radiopharmaceuticals are hig [...] hly relevant and desired. One of them is passiflora syrup (Passiflora incarnata L., Passifloraceae) which is widely used for depression, insomnia, anxiety and menopause period. The aim of current study is to evaluate possible effects of passiflora syrup on the biodistribution of 99mTc-DTPA and its blood cells uptake. DTPA was labeled with 99mTc radionuclide. Biodistribution studies were performed on male Wistar albino rats which were treated via oral feeding-gavage-method with either passiflora syrup or 0.9 % NaCl as control group for ten days. Blood samples were obtained by cardiac blood withdrawal from the rats and they were radiolabeled. The biodistribution results showed that the passiflora syrup decreased the uptake of 99mTc-DTPA in kidneys and in blood cells. 99mTc-DTPA being used widely as a kidney diagnostic agent in nuclear medicine seems to be interacting with orally taken passiflora. Passiflora syrup may modify the uptake of 99mTc-DTPA by kidney. The knowledge of this negative effect may contribute to reduce the risk of misdiagnosis and/or repetition of the examinations in nuclear medicine.

    Recent studies showed prominent antimicrobial activity of some plant extracts on some pathogenic microorganisms so we evaluated antimicrobial activity of aqueous extracts of clove and cinnamon using the agar well diffusion method. An in vivo study was carried out on 40 adult healthy male albino rats divided into four groups: Group 1: negative control group (received intragastric saline solution daily); Group 2: injected with mixed bacterial suspension of S. aureus and E.coli as a model of pyelonephritis then received intragastric saline solution daily; Group 3: injected with the same dose of mixed bacterial suspension then received intragastric clove extract 500 mg/kg/day; and Group (4): injected with mixed bacterial suspension then received intragastric cinnamon 500 mg/kg/day. Five rats from each group were sacrificed after 1 and 4 weeks. Serum and blood samples were collected for lysozymes activity and nitric oxide production, lymphocyte transformation test, as well as counting of both total and differential leukocytes and erythrocytes. Kidney samples were tested histopathologically. Both in vivo and in vitro results confirmed the efficacy of clove extract as natural antimicrobials and suggested the possibility of its use in treatment of such bacterial infections. PMID:25816407

    Creatine is known to rescue animals following brain damage. Present study was designed to demonstrate the effect of long term (15 week) supplementation of 2% creatine monohydrate (Cr), following neonatal hypoxic ischemic insult, on learning and memory formation in male albino mouse. Albino mice pups were subjected to right common carotid artery ligation followed by 8% hypoxia for 25 minutes. Following weaning, animals were separated and grouped on the basis of dietry supplementation for 15 weeks followed by a battery of neurological tests including Morris water maze, open field and rota rod. It was observed that HI mice fed on 2% Cr for 15 weeks performed better than their littermates mice on normal rodent diet during water maze (learning and memory) and rotating rod (neuro-muscular coordination and balance) test while the results of open field test remained unaffected. It was also observed that Cr treated animals had a reduced brain infarct volume than untreated but this difference did not reached statistical significance. We have also observed an overall increase in body weight in Cr treated mice during the study. Over all our results are indicating that long term Cr supplementation is beneficial for male albino following hypoxic ischemic insult. PMID:25445997

  6. The Vitamine D3 Analogue (1? Hydroxyvitamin D3) Aggravates Carbon Tetrachloride-Induced Hepatotoxicity In Albino Rats

    International Nuclear Information System (INIS)

    Provitamin D, cholecalciferol, undergoes hydroxylation at the 25 and the 1? position in the liver and the kidney, respectively, before it turns into a hormonally active form regulating calcium homeostasis. The main purpose of the present study is to assess the potential of the 1? hydroxyvitamin D3 analogue to aggravate the ability of carbon tetrachloride (CCl4) to cause hepatotoxicity in albino rats. For this purpose, four groups of male albino rats, each of five, were used as follow: control group (G 1) received no treatment, CCl4 treated group (G 2) received CCl4 at a dose of 0.2 ml/100 g body weight in sunflower oil (1/1) v/v ratio two times per week for three weeks subcutaneously, 1? hydroxyvitamin D3 treated group (G 3) received a total dose of 5 ng/g body weight of 1? hydroxyvitamin D3 dissolved in propyl alcohol divided into six doses each given twice weekly for three weeks via the subcutaneous route, and CCl4 + 1? hydroxyvitamin D3 treated group (G 4) received the same dose of CCl4 and 1? hydroxyvitamin D3 concomitantly as previously described. Liver tissues from sacrificed animals were fixed in 10% formalin before sectioning and stained with eosin and hematoxyline then were examined histopathologically. Sera from control and treated animals were separated from blood and examined for ALT, AST, alkaline phosphatase and LDH levels. Serum total protein, albumin, globulin, A/G, bilirubin, creatinine, phosphorous and Ca levels were also monitored. Data from the present study showed that administration of 1? hydroxyvitamin D3 aggravated CCl4-induced hepatotoxicity as evidenced by the exacerbation of the rise in serum ALT, AST, alkaline phosphatase levels. The analogue, however, had no effect on serum liver enzymes in CCl4 untreated rats. Though, CCl4 caused significant impairment of kidney function as shown by the rise in serum creatinine and urea levels which were differentially affected by the analogue. In conclusion, the 1? hydroxyvitamin D3 compound used widely in the treatment of hypocalcemia of different etiologies may aggravate the hepatotoxic potential of liver injurious agents and this should be considered in patients suffering from liver cirrhosis associated with hypocalcemia

  9. Gross hepatic changes in developing albino rats exposed to valproic acid

    International Nuclear Information System (INIS)

    Background: Valproid Acid (VPA) is a broad spectrum antiepileptic drug. Its use during pregnancy has been associated with congenital anomalies and hepatotoxicity. This study was designed to assess the effects of VPA on the gross structure of liver in developing albino rats exposed to the drug during various trimesters of pregnancy. Methods: In this experimental study 40 pregnant rats were divided into 4 equal groups A, B, C and D. Group A received VPA in a dose of 500 mg/Kg/day intraperitonealy (I/P) on days 3, 4 and 5 of gestation. Group B received the drug in a dose of 500 mg/Kg/day I/P on days 8, 9 and 10 of gestation. Group C received VPA in a dose of 500 mg/Kg/day I/P on days 16, 17 and 18 of gestation. Group D received no treatment and was kept as a control group. On day 21, the rats were euthanised by cervical dislocation. The liver of the foetuses were dissected out for the assessment of their gross structure. Results: Foetal liver of the experimental groups showed significant decrease in weight as well as relative tissue weight index (RTWI) as compared to the control group, although the gross appearance of the foetal liver was normal in all the groups. Conclusion: The use of VPA during various trimesters of pregnancy produces hepatotoxicity in the developing rats. So, the use of this drug during pregnancy should be carefully decided. (author)

  10. Comparative gastroprotective effects of natural honey, nigella sativa and cimetidine against acetylsalicylic acid Induced gastric ulcer in albino rats

    International Nuclear Information System (INIS)

    Natural honey (NH) and Nigella sativa (NS) seeds have been in use as a natural remedy for over thousands of years in various parts of the world. The aim of this study was to assess the protective effects of NS (Nigella sativa) and NH (natural honey) on acetylsalicylic acid induced gastric ulcer in an experimental model with comparison to Cimetidine (CD). The study was conducted on 100 male albino rats, divided into 5 groups, with 20 animals in each group. Group A was used as a control and treated with Gum Tragacanth (GT). Eighty animals of the other groups were given acetylsalicylic acid (0.2 gm/kg body weight for 3 days) to produce ulcers by gavage. Two animals from each group were sacrificed for the detection of gastric ulcers. The remaining 72 animals were equally divided in four groups (B, C, D and E). The rats in group B, C and D were given NS, NH, and CD respectively while those in E were kept as such. No gastric lesions were seen in control group A while all the animals in group E revealed gastric ulcers. The animals of group B, C and D showed healing effects in 15/18 (83%), 14/18 (78%) and 17/18 (94%) animals grossly; 13/18 (72%), 14/18 (78%) and 16/18 (89%) rats showed recovery on microscopic examination respectively. The healing effects were almost the same in all three groups therefore, the statistical difference was not significant among them (p =0.40 and 0.65) while significant from group E (p=0.0000075, 0.0000016 and 0.0000012 respectively). NS and NH are equally effective in healing of gastric ulcer similar to cimetidine. Further broad spectrum studies as well as clinical trials should be conducted before the use of these products as routine medicines. (author)

  11. Correction of glutathione metabolism in the liver of albino rats affected by low radiation doses

    International Nuclear Information System (INIS)

    The levels of total glutathione GSH, GSSG and the activities of glutathione reductase and glutathione peroxidase were studied in the liver of adult albino rats subjected to 3-fold external ?-irradiation throughout 2 weeks at the overall dose of 0.75 Gy after 15 h, 2 and 5 days from the last irradiation. Some animals were injected intraperitoneally with the pantothenate containing complex > 3 times on days 1-3 before the irradiation. The radiation related decrease of GSH, GSH/GSSG and the total glutathione level was prevented by the prophylactic administration of the complex and probably at the expense of the activation of the G-SH biosynthesis and/or transport in the liver by the CoA biosynthetic precursor.

    The negative chronotropic effects of acetylcholine were studied in the isolated atria of the hearts of albino rats aged 2, 15, 29 and 47 days and adult. In untreated preparations, i.e. with full cholinesterase activity, the strongest effects were observed in newborn animals; with advancing age the reaction grew weaker. If cholinesterase activity was inhibited with physostigmine, the differences between the various age groups were obliterated. It is thus evident that the actual acetylcholine sensitivity of the sinoatrial node tissue does alter during postnatal life, but that growing cholinesterase activity reduces the amount of acetylcholine diffusing from the medium into the acetylcholine receptor zone. The change which takes place in cholinesterase activity in the myocardial tissue during postnatal life is so great that is must be taken into account when considering the development of cholinergic control of cardiac function.

    Results: Microscopic changes in thyroid gland of albino rats were evident after 8 weeks of drug administration which include marked pleomorphism, shrinkage in size of thyroid follicles, excess of colloid and marked vacuolations in acini. At 12th week of study, follicles were found both macro and micro follicular, with variable lining epithelium and hyperchromatic nuclei. Lining epithelium of some follicles was disrupted. The stroma was infiltrated with lymphocytes and eosinophils and there were some interfollicular hemorrhages. Conclusions: Lithium given over prolonged period will cause macro and micro follicular goiter with hyperplastic epithelium and hyper chromatic nuclei, hyperplasia of stroma with increased vascularity, sometimes hemorrhages and finally may lead to thyroiditis like picture. So, it is advised that patients on lithium therapy should be periodically evaluated for thyroid dysfunction. [Int J Res Med Sci 2014; 2(1.000: 279-284

    International Nuclear Information System (INIS)

    The influence of ginger (Zingiber officinale) supplementation against gamma rays-induced immunosuppression in male albino rats was investigated in the present study. Twenty four male albino rats were divided into four equal groups; control group (receiving no treatment), ginger group where the rats received ginger orally at a dose of 15 g/rat/day for 120 consecutive days, gamma radiation group which subjected to a single 6 Gy whole body gamma radiation and gamma radiation plus ginger group where each rat after taking daily 15 g of ginger for 120 consecutive days was subjected to 6 Gy whole body irradiation. Complete blood pictures and immunoglobulin G (IgG) and M (IgM) were estimated and spleen tissue was also examined histologically. The data obtained revealed that exposure to 6 Gy of gamma radiation caused significant decrease in the body weight, spleen weight, IgG, IgM, erythroide and leucoid elements and produced histological damage in spleen tissue. On the other hand, ginger as a protective agent, caused significant amelioration in the changes produced by irradiation especially immunoglobulins leading to the conclusion that ginger supplementation for 120 days caused modulation of the humoral immune response in irradiated rats. In conclusion, these findings indicated that ginger has the regulatory effect against gamma rays-induced immunosuppression.

  17. The protective and/or curative effect of serotonin on sex hormones in gamma irradiated albino rats

    International Nuclear Information System (INIS)

    Studies were carried out to investigate the efficacy of serotonin as a potential radioprotector and/or therapeutic agent. Irradiation of male albino rats was applied in single doses at 6.5 and 10 Gy levels. The effect was traced on FSH, LH, PrL and testosterone in blood and testicular tissue. The data obtained revealed marked and significant protection both serum and testicular tissue for the lower dose level of 6.5 Gy. Serotonin proved to exert nonsignificant control of hormonal changes due to the higher dose level of 10 Gy. Serotonin administered after radiation exposure, showed partial curative role for changes in LH, whereas it failed to exert any significant therapeutic role on changes in FSH, PrL and tester one induced by either of the two applied dose levels. It could be concluded that serotonin played only a good role as radioprotector on all investigated hormones in serum and testis at the radiation dose level 6.5 Gy. 8 figs., 8 tabs

  18. Effect of aspirin and prostaglandins on the carbohydrate metabolism in albino rats.: glucose oxidation through different pathways and glycolytic enzymes

    International Nuclear Information System (INIS)

    The effect of chronic and acute doses of aspirin and prostaglandins F2? and E2 individually on the oxidation of glucose through Embden Meyerhof-TCA cycle and pentose phosphate pathways and some key glycolytic enzymes of liver were studied in male albino rats. Studies were extended to find the combined effect of PGF2? and E2 with an acute dose of aspirin. There was increased utilisation of both 1-14C glucose and 6-14C glucose on aspirin treatment. However, the metabolism through the EM-TCA pathway was more pronounced as shown by a reduced ratio of 14CO2 from 1-14C and 6-14C glucose. Two hepatic key glycolytic enzymes viz. hexokinase and pyruvate kinase were increased due to aspirin treatment. Withdrawal of aspirin corrected the above impaired carbohydrate metabolism in liver. Prostaglandin F2? also caused a reduction in the utilisation of 1-14C glucose, while PGE2 recorded an increase in the utilisation of both 1-14C and 6-14C glucose when compared to controls, indicating that different members of prostaglandins could affect metabolisms and differently. Administration of the PGs and aspirin together showed an increase in the utilisation of 6-14C glucose. (auth.)

    Full Text Available Food colorants are used all over the world in great amount. However, their use in food is still controversial. It causes and will cause severe tension to the consumers as the sensitivity of people increases to general health. This work was carried out to study and compare between the possible toxic effect of some natural (tumeric, carmine and chlorophyll and synthetic (fast green, annatto and sunset-yellow, food colorants on liver and kidney function of young male albino rats. Such effect might explain hyperactivity of children that was claimed associated with consumption of food colorants. The study revealed that administration of both natural and synthetic food colorants (permitted dose significantly increases serum AST and serum urea. All colorants with the exception of sun-set yellow significantly increase serum total bilirubin. While, chlorophyll, fast-green and sun-set yellow were significantly increase serum ALT. Some of the colorants used have a retard destructive effect on some vital organ functions, which extends even after the recovery period. Therefore, large quantities and /or long periods of colorants administration should not be used as additive in man's diet or as a drink. Hence, these colorants should restrictly be used in nutritional therapy. And more caring must be done prevent our children to eat or drink these colorants with much amounts or for long period.

    International Nuclear Information System (INIS)

    Wheat bran was mixed with standard rat diet in order to assess the role of high fiber diet on the damage induced by 4 Gy gamma irradiation in male rats. Immediately after exposure to irradiation, the male albino rats were fed on diet containing 10% wheat bran ad libitum. After 15 days, the rats were decapitated then blood picture, levels of calcium, glucose, folic acid, vitamin B12 , triiodothyronine (T3), thyroxine (T4), testosterone and insulin hormones were determined. The results denoted that wheat bran had an improvement effect on the radiation damage on blood picture, calcium level, vitamin B12 , folic acid and testosterone hormone, which most probably due to the effect of the high antioxidant action of wheat bran that might improve the gastro intestinal metabolism.

    International Nuclear Information System (INIS)

    Fifty mature male albino rats were used in the present study to evaluate the effect of using crude garlic for one month on general heath condition and to compare between garlic intakes pre and post-irradiated stressed rats.Fresh minced cloves (8-10) of garlic were added to the rat diet twice per day for 30 days in garlic group and for 7 and 15 days prior to and after 4 Gy irradiation in pre and post-irradiated garlic groups, respectively. The results denoted that the extensive use of garlic in food improved the general condition in non-stressed rats while in irradiated stressed rats, the immediate intake of garlic after radiation was more efficient in ameliorating the undesirable radiation effects, where some biochemical and hematological parameters were examined in pre and post-garlic intake such as Hb, RBCs, platelets, T3, testosterone and insulin.

  3. Effects of ciprofloxacin and zinc chloride in adult albino rat and pre-natal conceptus

    International Nuclear Information System (INIS)

    Background: Administration of quinolone therapy is controversial during growing age as stated by earlier authors. The flouroquinolones are currently not indicated for young children because of arthropathy and adverse effect as new born shown by studies. However the effects of ciprofloxacin and ZnCl/sub 2/ on prenatal conceptus have remained undocumented. The present study was designed to compare the effects on conceptus after maternal ingestion of ciprofloxacin and ZnCl/sub 2/ using Wastar albino rats. Methods: Ciprofloxacin and ZnCl/sub 2/ was administrated to pregnant female albino rats. Ciprofloxacin with a dose of 20 mg/Kg bodyweight and ZnCl/sub 2/ 120 micro g/100 gm bodyweight two times therapeutic dose for 10 days (from day 8-18 of pregnancy). Each animal was weighted on day 1, day 8 and day 18 of pregnancy. Abortion resulted on day 18th of pregnancy. Each group of pregnant animals were sacrificed on day 18 of gestation by over dose of either anaesthesia, abdomen opened, uterus and both cornua containing conceptus identified, removed, there weight recorded, crown rump length was measured and was compared with similar value of control animals. The results were statistically analysed to find out the significance. Results: The ciprofloxacin induces a mordanting effect as obviated by increased basophilia. Our study reveals that ciprofloxacin administered in maternal, decreased maternal body weight to 38.4+-0.9 gm. However simultaneous ZnCl/sub 2/ maintained the body weight to 41.4+-0.7 gm, while ZnCl/sub 2/ increased the body weight to 46.5+-2.25 gm. The body weight and Crown Rump length (CR Length) in conceptus decreased by 4.52+-0.10 gm and 3.06+-0.09 Cm respectively. That ciprofloxacin and ZnCl/sub 2/ administration maintained the body weight and CR length by 5.46+-0.09 gm and 3.79+-0.13 Cm respectively. That ZnCl/sub 2/ administration increased the body weight and CR length by 6.71+-0.05 gm and 4.15+-0.08 Cm respectively. Conclusion: Prenatal administration of Ciprofloxacin caused reduction in growth rate and CR length, and ZnCl/sub 2/ maintained body weight and CR length and growth of the rat conceptus. (author)

  4. Protection of radiation-induced DNA damage in albino rats by Zingiber Montanum extract

    International Nuclear Information System (INIS)

    The tropical ginger, Zingiber montanum (J. König) A. Dietr, has potentials in scavenging free radicals and affording protection from radiation-induced chromosomal aberrations. The present investigation aims at determining antioxidant and radioprotective properties of the rhizome extract. Sulphur free radical, DPPH and superoxide scavenging assays were carried out for assessing antioxidant activities. Radiation-induced (500 cGy) DNA damage in pBR322 in vitro could be significantly reduced upto 71% (P < 0.05) by treatment with 60% ethanol extract (20 ?g). Acute toxicity of the 60% ethanol extract was determined and suitable injectable dose was selected for intra-peritoneal administration in albino rats (Rattus norvegicus). The LD50 of extract calculated for 72 hrs was found to be 2.9 g/kg, and maximum tolerated dose (MTD) of rhizome extract was 1.3 g/kg. Rhizome extract (0.5 g/kg) in 60% ethanol was intra-peritoneally injected to albino rats and exposed to 100, 300 and 500 cGy. Radioprotective effect of the extract was determined by alkaline single cell comet assay. Significant reduction (P < 0.05) of comet DNA (68%) and length (61%)in rat bone marrow cells was observed at a radiation dose of 500 cGy. The results demonstrate that tropical ginger possess free radical scavenging properties and can protect bone marrow cells from radiation-induced DNA damages. The results on radiation induced DNA damage using plasmid pBR322 DNA obviously justify that the extract at a low dose can protect DNA from undergoing strand breakage due to gamma radiation exposure. Versatility of Zingiber montanum in different chemical assays in terms of its radical scavenging potential shows that this non-conventional food plant as a lot of potential in maintaining human health through dietary supplementation as nutraceutical. This candidate plant also can possibly be a promising candidate in clinical radiotherapy perhaps as a substitute of or the well-know radioprotector amifostine. (author)

    Full Text Available Background: The present study was undertaken, to evaluate the protective effect of sodium selenite against mercuric chloride induced oxidative stress in experimental rats. Female Albinos Wistar rats randomly divided into four groups, were the first was served as a control, whereas the remaining groups respectively treated with: sodium selenite (1mg/ kg b.w; ip, mercuric chloride (1 mg/kg body weight i.p and combination of sodium selenite and HgCl2. Change in liver enzyme activities, thiobarbituric acid reactive substances (TBARS level, antioxidants and reduced glutathione (GSH contents were determined after 10 days experimental period. Results: Exposure of rats to mercuric chloride caused a significant increase the lipid peroxidation level along with corresponding decrease in the reduced glutathione and various antioxidant enzymes in liver. And increase in serum: glucose level, APL and transaminases activities and decreased in total protein and albumin levels. Furthermore, treatment with mercuric chloride caused a marked elevation of liver weight and decreased body weight. Supplementation of sodium selenite resulted in decreased of lipid peroxidation level and in the serum: AST, ALT and APL activities were decreased along with increase in total protein, albumin and liver GSH levels. The activities of antioxidants enzymes: glutathione peroxidase (GSH -Px and glutathione –S-transferase (GST were also concomitantly restored to near normal level by sodium selenite supplementation to mercuric chloride intoxicated rats. Liver histological studies have confirmed the changes observed in biochemical parameters and proved the beneficial role of sodium selenite. Conclusion: The results clearly demonstrate that sodium selenite treatment augments the antioxidants defense mechanism in mercuric chloride induced toxicity and provides evidence that it may have a therapeutic role in free radical mediated diseases.

    In experiments on adult albino rats the authors used the substances BW 284 C51 (1.5-bis(allyldimethylammoniumphenyl)-pentane-3-one-dibromide) as a specific inhibitor of acetylcholinesterase (AChE) and ethopropazine (10-(2-diethylaminopropyl) phenothiazine hydrochloride) as a specific inhibitor of butyrylcholinesterase (BuChE) to determine the two enzyme activities in atrial homogenates and to investigate changes after AChE or BuChE inhibition of the negative chronotropic effect of acetylcholine (ACh) on atria incubated in vitro. AChE accounted for only 12% and BuChE for 88% of the total ability of atrial homogenates to hydrolyse acetylcholine. The concentration of exogenous ACh needed to reduce the spontaneous frequency of contractions of the isolated right atrium by 30, 60, or 90/min fell by 78%, 79% and 84% respectively after BW 284 C51 inhibition of AChE and by 95%, 94% and 94% after simultaneous inhibition of AChE and BuChE. The significance of AChE in control of the negative chronotropic effect of ACh is thus evidently significantly greater than would correspond to the percentual proportion of AChE in cholinesterase activities in the atria of the rat heart. In can be assumed that AChE is functionally associated with parasympathetic innervation of the heart and that it is probably present in a high concentration in the primary pacemaker region.

    Full Text Available The present study evaluated the effect of aspartame intake on the histological and genetic structures of mother albino rats and their offspring. Sixty adult female albino rats and 180 of their offspring were equally divided into two groups (control and treated, each group divided into three subgroups. Each subgroup consisted of 10 pregnant rats and 30 of their offspring. The experimental design divided into three periods: (1 the gestation period (subgroup one, (2 the gestation period and three weeks after delivery (subgroup two and (3 animals in the third subgroup treated as subgroup two then left till the end of the ninth week after delivery. Each pregnant rat in the treated subgroups was given a single daily dose of 1 mL aspartame solution (50.4 mg by gastric gavage throughout the time intervals of experimental design. At the end of each experimental period for control and treated subgroups, the liver of half of both control and treated groups were subjected for histological study while the liver and bone marrow of the other halves were subjected for cytogenetic studies. Body weight of both groups were recorded individually twice weekly in the morning before offering the diet. The results revealed that the rats and their offspring in the subgroups of control animals showed increases in body weight, normal histological sections, low chromosomal aberration and low DNA fragmentation. The treated animals in the three subgroups rats and their offspring revealed decreases in body weight, high histological lesions, increases in the chromosomal aberration and DNA fragmentation compared with control groups. In conclusion, the consumption of aspartame leads to histopathological lesions in the liver and alterations of the genetic system in the liver and bone marrow of mother albino rats and their offspring. These toxicological changes were directly proportional to the duration of its administration and improved after its withdrawal.

Good hygiene was maintained by constant cleaning and removal of faeces and spilled from cages daily. Rats in all groups were sacrificed 24 hours after the experimental periods of 21days of oral administration. Results: The result reveals a significant (P<0.05 increase in serum albumin in all the experimental groups when compared with the control. Likewise, serum globulin depicts a significant increase (P<0.05 while groups treated with Pefloxacin and mixture of Pefloxacin and ethanol leaf extract of Piliostigma thonningii showed significant (P<0.05 decrease when compared with the control. Except for group B which reveals a significant (P< 0.05 increase in serum bilirubin, Pefloxacin and mixture of Pefloxacin and ethanol leaf extract of Piliostigma thonningii showed a significant decrease when compared with the control. The serum AST concentration showed a significant (P<0.05 decrease when compared with the control. Liver AST and ALP reveals a significant decrease in groups administered with ethanol leaf extract of Piliostigma thonningii and mixture of Pefloxacin and ethanol leaf extract of Piliostigma thonningii while groups administered with the drug showed a significant (P<0.05 increase when compared with the control. Likewise, the Liver ALP showed a significant (P<0.05 increase in groups treated with the extract and drug alone while groups treated with both the extract and Pefloxacin showed a significant decrease (P<0.05 when compared with the control. Conclusion: The alterations on the liver functional indices studied suggest that ethanol leaf extract of p. thonningii possess a hepato protective effect, but with the evidence of hepatic injury/assault in groups treated with Pefloxacin but was significantly ameliorated in groups co- administered with the drug and the extract.

    Full Text Available Fluorides have been a cause of concern for scientists and environmentalists for the long because of their harmful effects on the human and animal life but the problem was highlighted during the twentieth century because of great increase in the human population and industrialization. Since fluorides accumulate in calcified and hard tissues of the body such as bone and teeth and can be detected easily in these tissues, so most of the previous studies focused on the effects of fluorides on these tissues. However, during the past decade researchers all over the world have felt that there is a need to study the effects of fluorides on various other tissues of the body including CNS as fluoride intake for prolonged period is known to cause abnormal behavioural pattern, grave implications for Alzheimer’s Disease, Dementia, Attention deficit disorder and reduced I.Q in children as the fluorides are known to cross blood brain barrier. Hence the present study has thrown light on the involvement of brain in chronic fluoride toxicity. The target organ of studied was cerebrum. In the Study, albino rats were exposed to 30 or 100 ppm fluoride (asNaF in drinking water for 3 months. Rats exposed to 30 ppm fluoride did not show any notable alterations in brain histology, whereas rats exposed to 100 ppm fluoride showed significant neurodegenerative changes in lhe motor cortex.Changes included decrease in size and number of neurons in all the regions, signs of chromatolysis and gliosis in the motor cortex. These histological changes suggest a toxic effect of high-fluoride intake & on chronic use. [J Interdiscipl Histopathol 2012; 1(1.000: 30-34

    Full Text Available The increased exposure to radiation in medicine or industries increases the hazards of radiation on various organs of the human body. The aim of this work was to evaluate the protective effect of anti oxidant (vitamin C against the effect of radiation on rat testes. Thirty adult albino rats were divided into three groups, each contained ten rats .The first group (G.1 was exposed to 415 r (G.1' or 622 r (G.1" using x-ray source for one minute per day for one week. The second group (G.2 was exposed to 415 r (G.2' or 622 r (G.2" using x-ray source for one minute per day for one week, in addition to vitamin C equivalent to 86.9 mg./liter orally for the two sub groups for the same period . The third group (G.3 was a control group. The examined testes of G.1 showed damaged germinal epithelium with remaining some layers of spermatogonia. There was no affection of spermatocytes, mature sperms, Sertoli cells and Leydig cells, the lumen contained little sperms and debris of germ cells (G.1' .While for (G.1" there was marked damage of the seminiferous tubules with irregular outline, destruction of spermatogonia, spermatocytes and spermatids with pyknotic type of nuclear degeneration and the lumen was devoid of mature sperms. The examined testes of the (G.2 showed evidence of almost complete recovery for G .2' and marked recovery for G.2" It is concluded that anti oxidants were essential to patients exposed to x-ray , to guard against its hazards.

    Full Text Available The seed products of Carica papaya have been proven as potential male contraceptives in laboratory animals. In this study, chromosomal aberrations were investigated in spermatogonia of albino rats and rabbits, following oral administration of Methanol Sub-Fraction (MSF of Carica papaya seeds. The experimental animals were divided into three groups, each group had 5 male Wistar rats and rabbits. In the first group, double distilled water served as negative control. The second group received monomeric acrylamide at 72.5 mg kg-1 body weight; two doses with a gap of 3 h served as positive control and in the third group, the MSF was orally administered at 500 mg kg-1 body weight (10 x contraceptive dose; CD; two doses with a gap of 3 h. The chromosomal fragments, dicentrics, rings, exchanges, damaged chromosomes and total chromosomal aberrations in MSF treated rats and rabbits were not significantly different when compared with negative control animals, however, were found to be reduced significantly (p<0.001 when compared with positive control group. The results suggested that the MSF did not induce chromosomal aberrations.

    Full Text Available Although being used for years in the treatment of tuberculosis, no data are available in the literature on the safety of pyrazinamide during pregnancy. Accordingly, we aimed to make a first approach to this problem by evaluating the effects of this drug administered during the entire pregnancy of albino rats. Fourty female, EPM-1 Wistar albino rats of about 250 g b.w. were used. Upon conception (day zero of pregnancy the animals were randomly divided in 4 groups of 10 rats each and labeled as follows. Controls (C, animals treated with the drug vehicle (destilled water; experimental groups (E1, E2 and E3, animals treated with 35, 105 or 315 mg/kg b.w. pyrazinamide by gavage (oral route once daily up to the term (20th day of pregnancy. Drug or vehicle volume was always 0.5 ml. Body weight gain was followed up every week. At term, upon sacrifice (in excess of anesthesia and histerectomy, the following parameters have been studied: number of implantations and reabsorptions; intrauterine deaths; number of living foetuses and of placentae; weights of concepts and of placentae; major foetal malformations; maternal mortality index. No significant effects of pyrazinamide on rat pregnancy have been observed regarding the maternal body weight gain, the weights of concepts, the number of implantations and reabsorptions and the weights of placentae and foetuses. Also, no deleterious effects have been noticed regarding major foetal malformations, intrauterine deaths or maternal mortality. With the highest pyrazinamide dosis employed (315 mg/kg b.w., however, a significant lowered uterine weight was recorded. Although otherwise safe, a high-dose regimen of pyrazinamide during rat pregnancy can induce a slight yet significant reduction of uterine weight.La pyrazinamida es un fármaco muy utilizado para el tratamiento de la tuberculosis, pero no hay datos en la literatura respecto a sus potenciales riesgos para la preñez. Debido a esto, en este trabajo tratamos ratas preñadas durante toda la gestación (desde el día 0 hasta el día 20 con 3 dosis de pyrazinamida (35, 105 o 315 mg/kg, una vez al día para una primera observación sobre los efectos de la pyrazinamida durante la preñez. Las ratas control recibieron el vehículo de la droga (agua destilada. Los resultados mostraron que no hubo alteraciones significativas en cuanto a la evolución del peso corporal de las ratsa madres, al peso de los fetos, al número de implantaciones y reabsorciones, ni tampoco en cuanto a los pesos de placentas y fetos. Además, no se observaron malformaciones fetales mayores, muertes intrauterinas o aumento de la mortalidad materna. El único efecto significativo observado con la dosis de 315 mg/kg de pyrazinamida, fue una reducción del peso uterino

    Full Text Available This study was carried out to investigate the impact of oral administration of chloroform extract of Carica papaya seed (CPE on implantation and pregnancy in female albino rats. The study was divided into three experimental sections. Each section was subdivided into 4 groups treated, respectively with 25, 50 and 100 mg kg 1 b.w CPE and 2.5% tween 80 in normal saline (vehicle for CPE; control. Rats in section 1 were treated with CPE for two weeks before mating (pre-coital. Rats in section 2 were administered CPE from day 1 of pregnancy till term (post coital while rats in section 3 received the extract for two weeks before mating and thereafter throughout term (pre and post-coital. Implantation sites and resorptions were determined in some of the pregnant rats after laparotomy. The gestation period, litter size and fetal weight were recorded in the remaining rats. The litters were also observed for any morphological alterations. The extract treated rats had significant decreases in litter size and implantation count (p<0.01. The percentage resorptions increased in a dose dependent manner while the fetal weight and morphology remain unchanged when compared with the normal untreated control groups. The percentage resorptions were high in CPE treated rats when compared with the control group. None of the 100 mg kg 1 b.w CPE treated female rats had litters. The results suggest that the chloroform extract of Carica papaya seed has anti-implantation and abortifacient properties in female albino rats.

    Full Text Available Introduction: Stress is an important factor of depression that causes the changes in various body systems. The forced swim test is a commonly used stressor test where rats are forced to swim in specially constructed tanks for a particular period where there is behavioral activation characterized by vigorous swimming and diving to search for alternate routes of escape. Animal health including human has been shown to be affected by the stressful events of life inducing situation which alters cognition, learning memory and emotional responses, causing mental disorders like depression and anxiety and stress in rats. Methods: The experiment was carried out with 12 healthy albino Wistar female rats weighing about 150-180gms. The animals were randomly divided into two groups of six animals each. Group – I (control, Group – II (Stressed Group. Group –II rats are placed in plastic tanks for 45minutes for15 days. Temperature of water was maintained at 20?C. During stress phase, the animals will be trained for forced swim test, behavioral changes observed by open field apparatus for emotions, and eight arm maze for memory & leaning, elevated plus maze for anxiety. Results: Forced swim stress causes to a significant change (p<0.05 on cognitive functions: motivation, learning and memory. Forced swim stress is the factor damaging the hippocampus causes repeated immobilization and produce atrophy of dendrites of pyramidal neurons and neuroendocrinological disturbances, controlled by the hypothalamo-pituitary-adrenal axis (HPA. Repeated stress in the form of forced swimming activates the free radical processes leading to an increase in lipid peroxidation in many tissues. Conclusion: This study reveals the effect of repeated forced swim stress causes wide range of adaptive changes in the central nervous system including the elevation of serotonin (5-HT metabolism and an increased susceptibility to affective disorders. The earlier findings have reported that chronic and acute stress procedures weaken working memory functions in rats. There are very fewstudies on sub acute forced swim stress on working memory status of the animal. The study was undertaken to assess the various behavioral changes by applying sub acute forced swim.

  2. Utilization of greenable albino mutation lines of thermosensitive genie male sterile rice (Oryza sativa L. ssp indica)

    International Nuclear Information System (INIS)

    Two greenable albino mutation lines W24 and W27 induced by 60Co gamma rays treatment on seeds of a thermosensitive genie male sterile (TGMS) rice c.v 2177S were investigated on their usefulness in two-line hybrid rice. The leaf color of W24 and W27 was similar and could be expressed in different temperature conditions. The first three leaves of W24 and W27 were ablinotic at extending, but changed into green after the fourth leaf extended. The greenable leaf area were about 40% for the first leaf and 90% for the third leaf. No significant differences were detected in morphoagronomic characters and styler extrusion rate between the mutation line and 2177S, which suggested that the mutation leaf color may be a useful marker in eliminating contamination of selfed seeds in two-line hybrid rice

    International Nuclear Information System (INIS)

    Solanine is a toxic compound produced in nightshades family as potato,tomato and eggplant when exposed to light.The current study was carried out on 18 female postmenopausal albino rats to investigate the effect of solanine on the symptoms of rheumatoid arthritis.Animals were classified into 3 groups feeding on balanced diet only (GI) or replaced by two third with small pieces of diseased potatoes for 2 and 4 weeks (GII,GIII) respectively . Serum levels of arthritic bio markers were investigated as the estimation of erythrocytes sedimentation rate ( ESR) , C-Reactive Protein (CRP), malondialdehyde (MDA),Tumor necrosis factor-? (TNF-?),Interleukin-6( IL-6) and Immunoglobulin G (IgG) were determined in all groups. There was a significant positive increase in the levels of ESR, CRP , MDA , TNF-?, IL-6 , and IgG among different groups depending on potatoes intake. There was positive correlation between the serum levels of CRP and TNF-? ,Il-6 and IgG.However, a non significantly positive correlation between serum level of CRP and the level of MDA was observed. The data of the present study showed that old age and postmenopausal suffering from arthritis and joint swollen must eliminat or avoid the nightshades plants to alleviate the joint pain and also decrease the destruction of the tissues

The results of the study showed that dihydroartemisinin treatment significantly elevated the total white cell count (pApproach: By increasing the population of neutrophils, lymphocytes and monocytes (which engage in chemo tactic response; microbial killing; microbial ingestion and antibody production in the blood, dihydroartemisinin demonstrated that it stimulates increase in their population and uses them as part of its own arsenals of warfare against endoparasites (like malaria parasites and pathogens. Results: The results of this study show that dihydroartemisinin stimulated a lot of new white blood cell production by haemopoetic sites of the body The increases in the total white blood cell count; the percentage neutrophils count and the percentage lymphocyte counts were significant at pConclusion: The results of the study suggest that the phagocytic and immunological activities of the body?s white blood cell population are important components of the efficacious Plasmodium Schizonticidal actions of Dihydroartemisinin in malaria treatment.

  5. Hematological and histopathological changes in female albino rats after gamma irradiation and /or piper nigrum treatment

    International Nuclear Information System (INIS)

    This study was carried out to investigate the effect of whole body gamma irradiation, at dose level of 6.0 Gy (single dose), and or daily treatment with P. nigrum (black pepper) at doses of 160 and 320 mg/kg body weight up to 36, 71 and 99 days on some hematological aspects as well as histopathological changes in lung, kidney and brain tissues of female albino rats. The results revealed that whole body gamma irradiation significantly elevated the values of red blood cells (RBCs), white blood cells (WBCs) and hematocrit percentage (HC %) but hemoglobin level was significantly decreased. These changes were ameliorated after treatment with P. nigrum. Non-significant changes were obtained regarding the effect of both doses of P. nigrum on red and white blood cell counts throughout the three time intervals. However, a dose of 160 mg/kg body weight of P. nigrum significantly reduced the hemoglobin contents throughput the experimental period. Histopathological examination revealed that lung, kidney and brain tissues showed marked to moderate pathological changes after irradiation and/or P.nigrum treatments. However, treatment with P. nigrum showed positive effect against the harmful effects of gamma irradiation, concerning kidney and brain. Although no malignant transformation could be detected, the resultant marked alveolar inflammation, bronchial wall hyperplasia and reactive astrocytic proliferation are important pathological changes that should be considered as pre-neoplastic changes

    Full Text Available Vitex-negundo Linn (Verbenaceae, a large aromatic shrub with typical five foliolate leaves pattern has been claimed to possess anticonsulvant activity apart from many medicinal properties. Maximal electroshock seizures (MES in albino rats were used to study anticonvulsant activity of Vitex-negundo leaf extract. The ethanol leaf extract of Vitex-negundo was administered orally in graded doses (500 and 1000 mg/kg and 2000mg/kg p.o in the experimental model and the effects were compared with Diphenylhydantoin in MES method as standard and normal saline as control. The Vitex-negundo in the doses 1000 mg/kg has significant effect and 2000mg/kg p.o showed protection against MES to a highly significant extent. Test drug in the dose (1000 mg/kg, po showed 60% protection in clonic seizures. It also decreased number and duration of convulsions significantly.These findings suggested that Vitex-negundo possesses anticonvulsant activity against MES induced convulsions. Vitex-negundo may be useful as an adjuvant therapy along with standard anticonvulsants and can possibly lower the requirement of Diphenylhydantoin and other anti convulsant drugs, Ethanol leaf extract of vitex ningundo significantly (P<0.01 decreased the duration of tonic extensor phase in MES-induced seizures. TheVitex-negundo extract showed a maximum inhibition (80% mortality against MES-induced seizures.Thus, it has been concluded that ethanolic extract of Vitex-negundo possesses anti-epileptic activity.

Chronic stress models in the working place comprise sleep deprivation, sedentary stress, and physical stress. The aim of this study was to evaluate the effect of various work stress models, such as stress from paradoxical sleep deprivation (PSD, immobilization, and footshock, on serum testosterone levels and number of Leydig cells in male albino rats. Methods This study was of experimental randomized post-test only with control group design using 24 male Wistar albino rats (Rattus norvegicus. The sample was divided into 4 groups: K1 (control, K2 (PSD, K3 (immobilization and K4 (footshock, receiving treatment for 25 days. Measured parameters were serum testosterone level and Leydig cell number. Analysis of variance (ANOVA was used for statistical analysis, followed by post hoc LSD. Results Mean serum testosterone levels (0.07 ± 0.08 ng/mL and Leydig cell numbers (4.22 ± l0.96 were lowest in the PSD stress model. Serum testosterone levels differed significantly between controls and PSD group (p=0.014, while there was a significant difference in numbers of Leydig cells between footshock stress and PSD (p=0.011 and between the three stress groups and controls (p=0.006. Conclusion This study demonstrated that PSD, immobilization and footshock stress significantly decreased serum testosterone levels and number of Leydig cells in male albino rats (Rattus norvegicus. The mechanism by which PSD affects serum testosterone is still unclear.

    Full Text Available Nephrolithiasis is the third most common disorder of the urinary system with high recurrence rate. Clinical treatment of lithiasis is costly and can cause harmful side effects and hence nowadays phytotherapy have higher clinical significance in kidney stone management. Aim of the study is to investigate the antilithiatic property of the methanol extract of Andrographis paniculata (MEAP in experimentally induced nephrolithiatic rats. Nephrolithiasis was induced in Wistar albino rats by administering the dose of 0.75% ethylene glycol for a period of 28 days. The experimental animals were divided into nine groups. Group I served as normal control. Group II received standard antilithiatic drug and group III as the lithiatic control. Group IV and V indicated as preventive regime, received 400mg/kg and 200mg/kg body weight MEAP and group VI, VII, VIII and IX indicated curative regime of which VI and IX received 400mg/kg extract and VII and VIII at 200mg/kg body weight of MEAP. At the end of the experimental period, serum (creatinine, blood urea, BUN, uric acid urine (protein, calcium and phosphorus and kidney (calcium and phosphorus were analyzed. All the elevated biochemical parameters in EG received group were declined in the MEAP treated groups at dosage of 200 and 400mg/kg. Urinary protein, phosphorus and calcium also declined in both MEAP treatment groups than the lithiatic groups. Serum creatinine declined significantly in high dose received group than its low dose in both post and co treatment groups. A dose dependent effect was observed in all the serum parameters except BUN. Kidney phosphorus and calcium of preventive regime which received MEAP at a high dose of 400mg/kg showed a clear dose dependent effect than the curative regimes. The result of the present study suggests the usefulness of MEAP against nephrolithiasis.

    Full Text Available Background: Diabetes mellitus is a global disabling and deadly disease found world-wide. Altered testicular structure and function have been observed in diabetic human and animal models of diabetes with impaired reproductive function. The testicular atrophy and infertility were common in untreated or poorly controlled diabetics. Aim of the work The present study was carried out to compare the protective effect of melatonin and chromium against testicular alterations in alloxan-induced diabetes in albino rats. Material and Methods: Thirty-five adult male albino rats were used in this study. The animals were divided into two main groups (each five: non diabetic and diabetic rats, the first group was subdivided into 3 sub-groups: normal control, melatonin-treated animals and chromium-treated animals. The second group was subdivided into 3 sub-group ( each five: diabetic, diabetic rats treated with chromium, and diabetic rats treated with melatonin. Diabetes was induced by a single intra-peritoneal injection of alloxan monohydrate in dose of 60 mg/ kg body weight (BW. The experiment was carried for forty-two days. Computer image analysis was used to measure the thickness of the basement membranes of the seminiferous tubules, the perimeter of the seminiferous tubules and the number of Leydig cells. Results: In diabetic rats the seminiferous tubules showed statistically significant decrease in diameter, irregular outline and deformed shape because there was degeneration and disappearance of germ cells from many tubules. There was significant thickening of the basement membrane of the seminiferous tubules also detected. Ultrastructurally, nuclei of germ cells showed rarefied chromium and separated areas of nuclear envelop. Spermatids showed abnormal condensed nuclear chromatin surrounded by membranes with focal areas of discontinuity together with vacuolation of Sertoli cell cytoplasm. Melatonin and chromium improved the diabetic alteration in the basement membranes, diameter of the seminiferous tubules and the number of Leydig cells but they did not return to the control values. The improvement with melatonin was more than that with chromium. Conclusion: From the present study, it could be concluded that, melatonin and chromium showed a protective effect on histological alterations of the testis of alloxan-induced diabetes in rats.

    India is one of the endemic areas where control of malaria has become a formidable task. Artesunate is the current antimalarial drug used to treat malaria, especially chloroquine resistant. The objective of the present study was to investigate the dose-dependent effect of oral administration of artesunate on the oxidative parameters in testes of adult male Swiss albino mice and ameliorative efficacy of curcumin, a widely used antioxidant. An oral dose of 150 mg/kg body weight (bwt; low dose) and 300 mg/kg bwt (high dose) of artesunate was administered for a period of 45 days to male mice, and ameliorative efficacy of curcumin was also assessed. The results revealed that artesunate caused significant alteration in oxidative parameters in dose-dependent manner. Administration of artesunate brought about significant decrease in activities of superoxide dismutase, glutathione, glutathione peroxidase, and glutathione reductase, whereas lipid peroxidation and glutathione-S-transferase activity were found to be significantly increased. The results obtained show that oxidative insult is incurred upon the intracellular antioxidant system of testis tissue by artesunate treatment. Further, administration of curcumin at the dose level of 80 mg/kg bwt along with both doses of artesunate attenuated adverse effects in male mice.

    The influence of progesterone in the brain and on the behavior of females is fairly well understood. However, less is known about the effect of progesterone in the male system. In male rats, receptors for progesterone are present in virtually all vasopressin (AVP) immunoreactive cells in the bed nucleus of the stria terminalis (BST) and the medial amygdala (MeA). This colocalization functions to regulate AVP expression, as progesterone and/or progestin receptors (PR)s suppresses AVP expressio...

  16. The Role of Antioxidants in Biochemical Disorders Induced by Arsenic in Adult male Rats

    International Nuclear Information System (INIS)

    The present investigation included biochemical, radiometric, molecular studies and histopathological examination to evaluate the protective role of Antox tablets toward Arsenic toxicity in adult male albino rats (Rattus rattus). Arsenic were given as sodium arsenate to different groups in drinking water at a dose of 100 mg/L, for 3 and 6 weeks led to severe tissue damage as revealed by an elevation of serum total protein and alteration of serum protein fractions. Using radioimmunoassay it was found that serum total testosterone level was significantly decreased. The decreased level of total testosterone paralleled the observed testicular damage. Treatment of male rats with antioxidant (Antox) along with arsenic led to an improvement in both the biochemical and histological alterations induced by arsenic. Thus the protective role of Antox is attributed to its antioxidant and free radicals scavenging properties of its components (selenium, vitamin A acetate, ascorbic acid and vitamin E).

    Full Text Available Aim of the study: This study was conducted to investigate the possible protective effects of L- treptophan "a precursor of melatonin" and alpha lipoic acid against L- arginine-induced experimental acute pancreatitis in albino rats. Methods: Fourty adult male albino rats (200- 250g were randomized into 4 groups (n= 10. Group I, the control group was given 0.9% saline intraperitoneally (i.p. Group II, was given 500 mg/100g L-arginine (i.p as a single dose to induce acute pancreatitis. Group III: was given 250mg/kg L-tryptophan (i.p 30 min prior to L- arginine injection. Group IV: was given 50mg/kg alpha lipioc acid(i.p 30 min prior to L-arginine. Before scarifice, blood samples were obtained from all groups to assay serum amylase and interleukin 6. Animals were sacrificed after 6 hours. For the histopathological study, pancreatic tissue was prepared for histological (H&E, PAS histochemical ( Tween stain for lipases and immunohistochemical ( Bax stain for apoptosis techniques. Both qualitative and quantitative analyses were done to assess the degree of acinar cells affection Results: It was revealed that serum amylase and interleukin 6 in group II rose rapidly. Microscopically, severe acinar cells degeneration, interstitial edema, diffuse bleeding and inflammatory infiltration were demonstrated. These changes were markedly improved with the administration of both L- tryptophan and alpha lipoic acid. Conclusion: It was concluded that both L- tryptophan & alpha lipoic acid reduced the effects of L-arginine-induced acute pancreatitis with better protection achieved by L-tryptophan administration.

  18. Antioxidant Evaluation of Methanolic Extract of Black Nightshades Ripe Fruits against Technical and Formulated Parathion-Induced Damage in Albino Rats

    International Nuclear Information System (INIS)

    Parathion in technical or formulated form at a sub-lethal dose of 1/20 LD50 was applied orally or dermally at 2-day interval for three months to determine its effect on RNA, DNA and protein content as well as RNA ase and DNA ase activity in different organs liver, brain and kidneys of adult male albino rats. Also, serum GOT, GPT and ALP activity as well as serum total soluble protein, albumin, globulin, bilirubin and uric acid content were determined in adult male albino rats (Rattus norvegicus). In addition, the present studies were undertaken to investigate different biological activities of the above parameters of black nightshades (Solanum nigrum L) methanolic extract. Two kinds of experimental works were taken off (antioxidants and protective). The results showed that technical and formulated parathion increased RNA and protein content but the content of DNA was insignificantly decreased in all rat organs tissue (liver, brain and kidneys) relative to control. The activity of RNA ase was also stimulated. In case of liver and kidney functions the present data observed that serum GOT, GPT and ALP activity was stimulated but total soluble protein, albumin and globulin content was decreased but the urea, uric acid and bilirubin content of serum was increased. Also, liver lipid peroxidation was elevated significantly either by technical or formulated parathion (ingested orally or induced dermally). It should be noted that formulated parathion ingested orally was the most effective, but the technical one had the lowest toxicity. The results of the present studies showed that crude methanolic extract of black nightshades ripe fruits has a strong antioxidant activity as showed by DPPH, nitric oxide scavenging, total reducing power, Fenton's reaction and total antioxidant capacity assay. Finally the the methanolic extract of the present medicinal plant observed a valuable influence as a protective agent in vivo in serum, liver, brain and kidneys damage of parathion intoxicated rats represented by improvements the all previous parameters which were disturbed by the both forms of parathion either induced orally or dermally

  19. Metabolic response to optic centers to visual stimuli in the albino rat: anatomical and physiological considerations

    International Nuclear Information System (INIS)

    The functional organization of the visual system was studied in the albino rat. Metabolic differences were measured using the 14C-2-deoxyglucose (DG) autoradiographic technique during visual stimulation of one entire retina in unrestrained animals. All optic centers responded to changes in light intensity but to different degrees. The greatest change occurred in the superior colliculus, less in the lateral geniculate, and considerably less in second-order sites such as layer IV of visual cortex. These optic centers responded in particular to on/off stimuli, but showed no incremental change during pattern reversal or movement of orientation stimuli. Both the superior colliculus and lateral geniculate increased their metabolic rate as the frequency of stimulation increased, but the magnitude was twice as great in the colliculus. The histological pattern of metabolic change in the visual system was not homogenous. In the superior colliculus glucose utilization increased only in stratum griseum superficiale and was greatest in visuotopic regions representing the peripheral portions of the visual field. Similarly, in the lateral geniculate, only the dorsal nucleus showed an increased response to greater stimulus frequencies. Second-order regions of the visual system showed changes in metabolism in response to visual stimulation, but no incremental response specific for type or frequency of stimuli. To label proteins of axoplasmic transport to study the terminal fields of retinal projections 14C-amino acids were used. This was done to study how the differences in the magnitude of the metabolic response among optic centers were related to the relative quantity of retinofugal projections to these centers

    Full Text Available The study aimed to evaluate the effect of metformin and the combined activity of P. daemia and metformin in the treatment of polycystic ovary syndrome (PCOS induced rats. Female albino wistar rats (150- 180 g were injected with Testosterone propionate (TP for the development PCOS. The PCOS induced rats were divided into two groups, one were treated with metformin and the other were treated with the combination of metformin and Pergularia daemia extract over a period of 15 days. The vaginal smear and histological studies proved the combined efficacy of metformin and the P. daemia extract by restoring the estrous cycle and re-establishment of the ovarian morphology. The biochemical and hormonal assays also confirms the same. Thus we conclude that the combined activity of metfromin and P. daemia extract is an effective medicine in treating PCOS than metformin alone.

    Full Text Available Hyperlipidemia is a predominant risk factor for atherosclerosis and associated cardiovascular diseases (CVD. The international guidelines issued by the World Health Organization recommend a reduction in dietary saturated fat and cholesterol intake as a means to prevent hypercholesterolemia and CVD. The main objective of the current investigation was to evaluate the effects of feeding blended oils consisting of coconut oil (CNO with different proportions of Tiger nut oil (TNO on serum lipid levels in Albino rats. GLC analysis was performed to illustrate the fatty acid composition of the blended oils. Blended oils were obtained by mixing tiger nut oil with coconut oil at the volume ratios of 100:0, 70:30, 50:50, 25:75, 10:90 and 0:100. Fifty-six male albino rats were randomly divided into 7 groups of 8 rats each according to the oil type. The blended oils were fed to rats for a period of up to 10 weeks. Total cholesterol (T-Ch, high-density lipoprotein cholesterol (HDL-Ch, low-density lipoprotein cholesterol (LDL-Ch, and triglycerides (TG, were determined. The atherogenic Index (AI was calculated. The results showed that non-significant changes in all nutritional parameters were observed between the control group and the rats fed with the tested oils. The results also indicate that coconut oil had 86% saturated fatty acids. On TNO contains 66% oleic acid. Therefore, blending coconut oil with tiger nut oil can reduce the proportions of saturated to unsaturated fatty acids in CNO. The rats that were fed blended oils showed significantly reduced levels of serum cholesterol as compared to those fed CNO. The HDL levels were marginally enhanced in the rats that were fed blended oils. The total cholesterol and LDL cholesterol levels were controlled when TNO/CNO proportions varied between 25/75 and 70/30. This was reflected in the calculation of the atherogenic index. Similar changes were observed with serum triglyceride levels.

    La hiperlipidemia es un factor de riesgo predominante para la aterosclerosis y las enfermedades cardiovasculares asociadas (ECV. Las directrices internacionales emitidas por la Organización Mundial de la Salud recomiendan una reducción de grasas saturadas y colesterol, como medio para prevenir la hipercolesterolemia y las enfermedades cardiovasculares. El principal objetivo de la presente investigación fue evaluar los efectos de una alimentación conteniendo mezclas de aceites, que consiste en aceite de coco (CNO con diferentes proporciones de aceite de chufa (TNO, sobre los niveles de lípidos en suero en ratas albinas. Se realizó un análisis GLC para determinar la composición de ácidos grasos de los aceites mezclados. Los aceites se obtuvieron mezclando aceite de chufa con aceite de coco en las relaciones:100:0, 70:30, 50:50, 25:75, 10:90 y 0:100 (volumen:volumen. Cincuenta y seis ratas albinas macho se dividieron aleatoriamente en 7 grupos de 8 ratas cada uno, según el tipo de aceite y se alimentaron durante un período de hasta 10 semanas con las mezclas de aceites. Se determinó el colesterol total (T-Ch, colesterol en lipoproteínas de alta densidad (HDL-Ch, colesterol en lipoproteínas de baja densidad (LDL-Ch, triglicéridos (TG y el índice aterogénico (IA. Los resultados mostraron cambios no significativos en todos los parámetros nutricionales entre el grupo control y las ratas alimentadas con los aceites ensayados. Los resultados también indican que el aceite de coco tiene un 86% de ácidos grasos saturados. TNO por otro lado contiene un 66% de ácido oleico. Por lo tanto, una mezcla de aceite de coco con aceite de chufa reduce la relación de ácidos grasos saturados a insaturados del CNO. Las ratas alimentadas con las mezclas de aceites mostraron niveles significativamente mas bajos de colesterol en suero en comparación con los de CNO. Los niveles de HDL mejoraron ligeramente en las ratas alimentadas con las mezclas de aceites. El colesterol total y colesterol LDL estuvieron controlados cuando las proporciones TNO / CNO variaron entre el 25/75

    Full Text Available Fatty liver causes were markedly increased in Egyptian people throughout last years. People prefer to use the medicinal plants instead of using chemical compounds because they are cheap and have few side effects compared to chemical compounds. Ginger is a natural dietary rhizome with anti-oxidative, anti-inflammatory, and anti-carcinogenic activities. The aim of this study was to evaluate the possible potential therapeutic and protective effects of Zingiber officinale (ginger against oxytetracyclin-induced fatty liver in an attempt to understand its mechanism of action, which may pave the way for possible therapeutic applications. Material and Methods: Albino rats were divided into two major groups, 15 rats for each. The first group was divided into three sub-groups: a control, b fatty liver group; that was injected intraperitonealy with oxytetracycline (120mg/kg for three consecutive days and c ginger treated group; which was treated with ginger water extract (125 mg/kg for 30 days after fatty liver induction . All animals were scarified after 33 days of the beginning of the experiment. The second group was divided into three subgroups: a control, b fatty liver group; that was injected intraperitonealy with oxytetracycline (120 mg/kg for three consecutive days and c ginger protective group; which received ginger for 15 days before induction of fatty liver, then sacrificed after induction of fatty liver (3 days. Blood samples were collected for biochemical analysis. Liver specimens were obtained and fixed in 10% formalin for histological study. Results: Fatty liver groups showed high significant increase in serum glucose, cholesterol, triglycerides, LDL cholesterol, ALAT, ASAT, GGT, LDH, urea, creatinine and A/G ratio while total protein, albumin, globulin and HDL cholesterol were significantly decreased compared to control group. These biochemical changes were accompanied with histopathological alterations in fatty liver tissue. The treatment with ginger ameliorated most of the evaluated biochemical parameters and improved the induced degenerative histopathological changes. The pre-treatment with ginger before the induction of fatty liver gave some protection against factors that experimentally induced fatty liver. Conclusion: Ginger as diet additive is recommend for fatty liver patients or those people who have hyperlipidemic family history.

    Creatine monohydrate (Cr) is a dietary supplement known to improve cognitive functions and has positive therapeutic results under various clinical conditions. The aim of this study was to determine the effect of 2 % Cr supplementation on learning, memory formation, neuromuscular coordination, exploratory and locomotory in male albino mice following hypoxic ischemic insult. At postnatal day, 10 male albino mice pups were subjected to right common carotid artery ligation followed by 8 % hypoxia for 25 min. On postnatal day 20, male mice were separated from the litter and divided into two groups on the basis of special diet supplementation. One group was supplemented with 2 % Cr in diet while the other group was raised on ordinary rodent chow for 8 weeks. Behavioral observations were made during rota rod, open field and Morris water maze test for both treatments. It was observed that supplementation with 2 % Cr for 8 weeks following neonatal brain damage resulted in enhanced muscular strength, neuromuscular coordination and improved body weight. In Morris water maze test, it was observed that Cr supplementation significantly improved mean swimming speed and mice on 2?% Cr diet covered more distance but the spatial memory was not improved significantly following hypoxia ischemia encephalopathy (HIE). Open field parameters and percentage of infarct volume remained unaffected following Cr supplementation. We concluded that 2 % dietary Cr supplementation has a potential to improve the muscle strength and body weight in male albino mice following (HIE) and should be considered for the treatment of neurological ailments.

  6. Hazardous Effects of Potato Chips and Ketchup (fast food) Consumption on Albino Rats

    International Nuclear Information System (INIS)

    Nowadays, it is easy and common to eat unhealthy food with poor nutritional value, low micro nutrients and high content of calories which may called junk or fast food. The present study aimed to shed the light on the hazardous effects of long term consumption of potato chips and ketchup as a model of the most popular fast food toppings or garnishing accessories. Eighty male and female rats were divided into four equal groups, each of ten rats. For four weeks, the animals were fed on basal diet (group 1), basal diet supplemented with 2 g of potato chips (group 2), basal diet supplemented with 1 g ketchup (group 3) while group 4 was supplemented with 2 g potato chips + 1 g ketchup beside their basal diet. The mortality was recorded in all treated groups but reached the maximum rate in males of group 4. The toxicological symptoms like tremors, dermatitis with general hair loss from the body, especially on the face region and eye bulge, were found in almost treated groups. The red blood cells count (RBC), haemoglobin (Hb) and hematocrit (Hct) were significantly decreased in group 2 (supplemented with potato chips) and group 4 (supplemented with both potato chips + ketchup) as compared with control one. Significant reductions in white blood cells count (WBC) were observed in rats of groups 2 and 4 except in females of group 2. Lipid profile was affected seriously, especially in rats of group 2 (supplemented with potato chips), whereas significant increases were recorded in TC, TG, LDL-C and atherogenic index, and significant reduction in HDL-C, especially in males, was recorded. The testosterone level was significantly reduced in all treated groups as compared to control group. The estradiol level was significantly increased in groups 2 and 4 as compared to group 3 and controls. In all parameters, the males were more seriously affected than females which may be related to gender differences in body composition, estrogen levels, growth rate, differences in food metabolism and toxin elimination, and group 4 was the most dangerously affected group. The present study revealed that potato chips is dangerous for human health and we should decrease our consumption from it as possible and try to return to the home made balanced diet with plenty of fruits and vegetables and avoiding deep fried food.

    Full Text Available The reproductive performance of rats given graded levels of the Nigerian Qua-Iboe brent crude oil was investigated in 32 female wistar albino rats. The experiment was divided into three parts, whereby, crude oil was given orally at the dose of 0.1, 0.2 and 0.4 mL, corresponding to Groups A, B and C, respectively, for four weeks, while the untreated group served as control (Group D. Experiment one investigated the effect of the crude oil on the oestrous cycle in rats divided into four groups of four replicates, monitored for four consecutive cycles for regularity of oestrous cycle using vaginal cytology. Three of the four groups were drenched with graded levels of the crude oil while remaining group served as the control. Experiment two investigated the effect of crude oil on gestation, using another set of female Wistar albino rats which were grouped and drenched as in experiment one. Mating was monogamous, while drenching done every other day following mating. The gestation length, litter size, stillbirth and gross malformation of foetuses were monitored. The same group of animals in experiment two was used for experiment three, whereby the animals were drenched prior to mating and until parturition. Results showed irregularity of oestrous cycle in the drenched groups, with significant differences (p<0.05 existing between the experimental group and control group considering stillbirths, conception rates, gestation length and litter size. These findings suggested that exposure to Nigerian Qua-Iboe Brent crude oil affected the reproductive performance of the rats.

    Full Text Available Moringa oleifera is a multipurpose tree, cultivated in the tropics and sub-tropics for its nutritional and therapeutic properties. The raw matured seeds which have been reported to be used as food and clarifying agent of turbid water caused growth retardation in albino rats and this might have been due to its anti-nutritional contents. Owing to these adverse factors, the effect of soaking the seeds for 30 min and then compounding it as feeds was done. Its effect on growth rate and the level of some biochemical parameters on rats were investigated. The Wistar albino rats were fed for 21 days and their weights measured at 2 days interval. Aspartate and Alanine transaminases, Alkaline phosphatase and total bilirubin levels were assayed using Automated Vitros 350 Chemistry Analyzer. The growth rates of rats fed with the commercial rat pellets, Casilan diet and the processed Moringa seed diet had a range of 80.06±3.54 to 100.98±5.37, 66.70±7.54 to 55.23±7.47 and 52.99±4.15 to 35.47±2.26, respectively. The parameters assayed for the group that received the processed Moringa seed diet are 144.00±16.80 (AST, 41.00±7.05 (ALT, 66.50±8.80 (ALP and 12.45±1.18 (Total Bilirubin. The one-way ANOVA statistical analysis indicated that there was no significant change in the parameters of all the groups at 95% significance level (pMoringa oleifera seed did not support growth in the animal subjects and also did not pose a threat to the liver. However, it is better to develop more suitable processing methods to improve the seed’s nutritional capabilities.

    International Nuclear Information System (INIS)

    The Antioxidant effect of Sumac; Rhus coriaria L. against whole body gamma-irradiation-induced oxidative damage in lung and liver tissues was investigated in albino rats. To achieve the ultimate goal of this study, 48 adult rats were randomly divided into 4 groups of 12 animals each. Group I: Control group. Group II: Irradiated with a single dose of 5Gy gamma-rays. Group III: Fed with sumac orally (300 mg/ kg body wt/ day) for 10 days. Group IV: Fed sumac (300 mg/ kg body wt) for 3 days pre-irradiation and 7 days after-radiation (5 Gy). The rats were sacrificed 1 and 7 days after a single exposure to ?-rays. The animals exposed to gamma radiation recorded significant increase in malondialdehyde (MDA) and total nitrate oxide (NO) levels in both lung and liver tissues. Also the results revealed, significant decrease in the activities of catalase (CAT), superoxide dismutase (SOD), glutathione peroxidase (GSHPx) and the level of reduced glutathione (GSH), in lung and liver tissues. Moreover, a significant increase in plasma glucose accompanied with a significant decrease in insulin level was observed in irradiated rats. Administration of sumac for 10 days to rats prior and post gamma irradiation improved the tested parameters except glucose. In conclusion, data obtained from this study indicated that sumac could increase the antioxidant defence mechanism in rat and there by protects the animals from radiation-induced organs toxicity but it may increase the blood sugar, therefore in diabetic patient be considered

    Recent studies showed prominent antimicrobial activity of various plant extracts on certain pathogenic microorganisms, therefore we prepared crude aqueous extracts of black pepper, ginger and thyme and carried out an in vitro study by measuring antimicrobial activity of these extracts using the agar well diffusion method. An in vivo study was carried out on 50 adult healthy male albino rats which were divided into 5 groups, 10 rats each. Group 1: negative control group which received saline solution intragastrically daily; Group 2: Positive control group, injected with mixed bacterial suspension of S.aureus and E.coli as a model of pyelonephritis, then received saline solution intragastrically daily; Group 3: injected with the same dose of mixed bacterial suspension, then received 100 mg/kg/day black pepper extract intragastrically; Group 4: injected with mixed bacterial suspension then received 500 mg/kg/day ginger extract intragastrically. Group 5: injected with mixed bacterial suspension then received 500 mg/kg/day thyme extract intragastrically. All groups were sacrificed after either 1 or 4 weeks. Serum and blood samples were collected for lysozyme activity estimation using agarose lysoplate, measurement of nitric oxide production, and lymphocyte transformation test as well as for counting both total and differential leukocytes and erythrocytes. Kidney samples were tested histopathologically. Both in vivo and in vitro results confirm the efficacy of these extracts as natural antimicrobials and suggest the possibility of using them in treatment procedures. PMID:25572733

  15. Response of plasma and urinary uric acid, creatine and creatinine to dietary protein deficiency and/or whole body gamma-irradiation in desert rodent and albino rats

    International Nuclear Information System (INIS)

    The effect of whole body gamma-irradiation on the levels of plasma and urinary uric acid, creatine and creatinine was studied in the desert rodent, Psammomys obesus and albino rats subjected to dietary protein deficiency. In albino rats, the levels of uric acid in plasma and urine were higher in the animals kept on high protein diets than in those maintained on non-protein ones. Radiation exposure caused a significant increase in uric acid concentration both in plasma and urine of albino rats, whereas in Psammomys obesus obesus, it exerted a significant drop in uric acid concentration in blood paralleling a marked rise in the daily uric acid excretion in the urine, especially with the high radiation level of 1170 r. Creatinine concentrations in plasma and urine of albino rats were higher than the corresponding values in Psammomys obesus obesus. Radiation exposure in general caused an increase in the creatinine concentration in blood and a decrease in its concentration in urine. Plasma creatine was shown to increase due to the effect of radiation exposure. This runs in parallel with the increase in the excretion of creatine in urine. Creatinuria observed in whole body irradiation is obviously caused by a defect in the ability of skeletal muscle to take up creatine from blood. Such abnormality could be the result of direct damage to the muscle caused by incident radiation

  16. Biochemical studies on gamma irradiated male rats fed on whey protein concentrate

    International Nuclear Information System (INIS)

    This study carried out to investigate the possible role of whey protein protein concentrate in ameliorating some biochemical disorders induced in gamma irradiated male rats. Forty eight male albino rats were divided into four equal groups: Group 1 fed on normal diet during experimental period. Group 2 where the diet contain 15 % whey protein concentrate instead of soybean protein . Group 3 rats were exposed to whole body gamma radiation with single dose of 5 Gy and fed on the normal diet. Group 4 rate exposed to 5 Gy then fed on diet contain 15 % whey protein concentrate, the rats were decapitated after two and four weeks post irradiation. Exposure to whole body irradiation caused significant elevation of serum ALT, AST, glucose, urea, creatinine and total triiodothyronine with significant decrease in total protein, albumin and thyroxin. Irradiated rats fed on whey protein concentrate revealed significant improvement of some biochemical parameters. It could be conclude that whey protein concentrate may be considered as a useful protein source for reducing radiation injury via metabolic pathway.

    Full Text Available Lactogenic effect of ethyl acetate fraction of Hibiscus sabdariffa seed was evaluated on serum prolactin and milk production in lactating albino rats. Twenty four lactating rats were grouped randomly at parturition into control, metoclopramide-treated and Ethyl-acetate-treated group consist of six rats in each group (n = 6. The lactating rats were administered control (normal saline, metoclopramide (5 mg/kg and ethyl-acetate fraction (100 and 200 mg/kg respectively from day 3-17 of lactation. Milk yield for rats were estimated by pup weight and weight gain. The animals were then euthanized on the day 18 and serum prolactin was analyzed using prolactin kit. The prolactin level of ethyl-acetate fraction of Hibiscus sabdariffa howed a significant increase (p<0.01 when compared to control group. Pup weight gain was also significantly higher (p<0.05 than the control group. This can be deduced that ethyl-acetate fraction of Hibiscus sabdariffa L. seed has lactogenic activity because it increases serum prolactin level and milk production in lactating female albino rats. Hibiscus sabdariffa L. seed stimulate prolactin synthesis; release and milk production in albino rats and it is affordable and safe for consumption.

    Stress is common for all organisms either in the form of eustress (beneficial) or as distress (harmful). Stress is highly diverse in present world and its effects in organisms are well studied. This study is a comparative effect of stress in the generation of reactive oxygen species in albino Wistar rats, which are seldom reported. Here animals were grouped into four and the test animals of each group were administered with any one of the following stress, namely forced swimming induced stress (FS), and noise induced stress (NS), immobilization stress (IS) and overcrowding stress (OS). After stress administration, serum cortisol was estimated as a bio marker of stress in the albino rats, and the liver homogenate were used to estimate superoxide dismutase (SOD) by using rat Elisa kit in the spectrophotometer. The data were processed with unpaired 't' test. The cortisol levels were found to be increased in a highly significant level (P stress level was found to be maximum in the FS group in comparison with other groups. The mean cortisol level in different stress groups such as FS, NS, IS and OS were found to be 4.15, 3.7, 3.63, 3.62 ? gm/dl respectively. Among all the stressed groups, the SOD level in the FS group were found to be increased in a highly significant level (P < 0.001) in comparison with normal control group. The SOD level in FS group was (30.75 U/mgm. protein) followed by OS (28.96), noise (28.88) and IS (28.77). PMID:25906605

    Purpose Biological sex and age are considered as two important factors that may influence the function and structure of the retina, an effect that might be governed by sexual hormones such as estrogen. The purpose of this study was to delineate the influence that biological sex and age exert on the retinal function and structure of rodents and also clarify the effect that the estrus cycle might exert on the retinal function of female rats. Method The retinal function of 50 normal male and female albino Sprague-Dawley (SD) rats was investigated with the electroretinogram (ERG) at postnatal day (P) 30, 60, 100, 200, and 300 (n = 5–6 male and female rats/age). Following the ERG recording sessions, retinal histology was performed in both sexes. In parallel, the retinal function of premenopausal and menopausal female rats aged P540 were also compared. Results Sex and age-related changes in retinal structure and function were observed in our animal model. However, irrespective of age, no significant difference was observed in ERG and retinal histology obtained from male and female rats. Notwithstanding the above we did however notice that between P60 and P200 there was a gradual increase in ERG amplitudes of female rats compared to males. Furthermore, the ERG of premenopausal female rats aged 18 months old (P540) was larger compared to age-matched menopausal female rats as well as that of male rats. Conclusion Our results showed that biological sex and age can influence the retinal function and structure of albino SD rats. Furthermore, we showed that cycled female rats have better retinal function compared to the menopausal female rats suggesting a beneficial effect of the estrus cycle on the retinal function.

    The present study was designed to investigate the in vivo effects of monosodium glutamate (MSG) and aspartame (ASM) individually and in combination on the cognitive behavior and biochemical parameters like neurotransmitters and oxidative stress indices in the brain tissue of mice. Forty male Swiss albino mice were randomly divided into four groups of ten each and were exposed to MSG and ASM through drinking water for one month. Group I was the control and was given normal tap water. Groups II and III received MSG (8 mg/kg) and ASM (32 mg/kg) respectively dissolved in tap water. Group IV received MSG and ASM together in the same doses. After the exposure period, the animals were subjected to cognitive behavioral tests in a shuttle box and a water maze. Thereafter, the animals were sacrificed and the neurotransmitters and oxidative stress indices were estimated in their forebrain tissue. Both MSG and ASM individually as well as in combination had significant disruptive effects on the cognitive responses, memory retention and learning capabilities of the mice in the order (MSG+ASM)>ASM>MSG. Furthermore, while MSG and ASM individually were unable to alter the brain neurotransmitters and the oxidative stress indices, their combination dose (MSG+ASM) decreased significantly the levels of neurotransmitters (dopamine and serotonin) and it also caused oxidative stress by increasing the lipid peroxides measured in the form of thiobarbituric acid-reactive substances (TBARS) and decreasing the level of total glutathione (GSH). Further studies are required to evaluate the synergistic effects of MSG and ASM on the neurotransmitters and oxidative stress indices and their involvement in cognitive dysfunctions. PMID:24556450

    During the last several decades, numerous studies have been performed aiming at the question of whether or not exposure to radiofrequency radiation (RFR) influences the permeability of the blood-brain barrier (BBB). The objective of this study was to investigate the effect of RFR on the permeability of BBB in male and female Wistar albino rats. Right brain, left brain, cerebellum, and total brain were analyzed separately in the study. Rats were exposed to 0.9 and 1.8 GHz continuous-wave (CW) RFR for 20 min (at SARs of 4.26 mW/kg and 1.46 mW/kg, respectively) while under anesthesia. Control rats were sham-exposed. Disruption of BBB integrity was detected spectrophotometrically using the Evans-blue dye, which has been used as a BBB tracer and is known to be bound to serum albumin. Right brain, left brain, cerebellum, and total brain were evaluated for BBB permeability. In female rats, no albumin extravasation was found in in the brain after RFR exposure. A significant increase in albumin was found in the brains of the RF-exposed male rats when compared to sham-exposed male brains. These results suggest that exposure to 0.9 and 1.8 GHz CW RFR at levels below the international limits can affect the vascular permeability in the brain of male rats. The possible risk of RFR exposure in humans is a major concern for the society. Thus, this topic should be investigated more thoroughly in the future. PMID:22047463

    Full Text Available To study the effects of ?-carotene on the body growth and physiological antioxidants, male weanling rats were fed with low and high amount of ?-carotene before four weeks and after six months of Aflatoxin-B1 (AFB1 treatment (0.5 mg kg-1 body wt., on alternate days, total 10 doses, i.p. The results were compared with animals treated with AFB1. The final body weight of AFB1 treated animals was significantly reduced in the normal group (NVE. Plasma vitamin E was reduced significantly in NVE group whereas vitamin C levels decreased significantly in NVE and low ?-carotene (LBE fed group. The maximum reduction was found in NVE group. Plasma GSH levels were increased significantly in animals in high ?-carotene (HBC fed group. Liver protein showed significant reduction in NVE group. Liver lipid peroxidation was increased significantly in NVE and LBE groups. Liver vitamin A showed dose dependent increased levels in animals fed with high amount of ?-carotene. Vitamin E was decreased significantly in NVE group. Liver antioxidative enzymes glutathione peroxidase, catalase and glutathione-S-transferase levels were reduced significantly in the treated animals of the NVE group. Results obtained indicated that ?-carotene supplementation elevated the levels of vitamin C, glutathione and glutathione related enzymes which act as a free radical scavenger and reduced the toxicity effect of AFB1 in rats.

    The authors studied the effect of repeated elevation of sympathetic activity on the postnatal development of the noradrenaline content of tissues of the albino rat. Between the ages of 15 and 29 days, young rats were forced to swim in water heated to 25 degrees C, 3 X 30 min on weekdays and 1 X 30 min on Saturdays and Sundays. At 30, 45 and 65 days, the noradrenaline content of the tissues was determined spectrofluorometricaLly by the trihydroxyindole method. The noradrenaline content of the heart of trained rats was higher than in the controls in all the given age groups and the size of the absolute difference rose with advancing age. The noradrenaline content of the spleen developed similarly. Repeated exercise did not lead to an increase in the noradrenaline content of skeletal muscle. The results show that the repeated elevation of the activity of sympathetic adrenergic neurones which occurs in young rats during exercise is a long-term factor stimulating the development of sympathetic innervation of the heart and spleen. The development of the neurones innervating skeletal muscle was not stimulated, probably because the activity of these neurones is not increased by stress. PMID:2931735

    The aim of this study was to evaluate transmission of Brucella abortus biotype 1 via sexual intercourse in rats. Male and female virgin Sprague-Dawley (SD) rats were experimentally infected intraperitoneally with 1×10(9)colony forming units (CFU) of B. abortus biotype 1, a Korean bovine isolate. At 14 days after infection, infected male rats (n=10) were housed with uninfected female rats (n=10) and infected female rats (n=10) were housed with uninfected male rats (n=10) for a period of one month. During this period all uninfected female rats became pregnant and 6 of 10 infected female rats became pregnant. Serum from two out of 10 female uninfected rats had positive reactions in the Rose Bengal Plate Agglutination Test (RBPAT), Tube Agglutination Test (TAT) or the Enzyme-Linked Immunosorbent Assay (ELISA); whereas none of the uninfected male rat had positive reactions in these tests. Using bacteriological culture and AMOS-PCR assay, B. abortus biotype 1 was isolated and identified from two uninfected female rats and all of the uninfected male rats were found negative for B. abortus biotype 1. It was concluded that transmission of B. abortus biotype 1 from infected male to uninfected female rats resulted from sexual intercourse. PMID:23664185

  7. Study On The Effect Of Cooking Of Some Food Proteins By Short-Term Radiation (Microwave) On The Functions Of The Liver And Kidney In Albino Rats

    International Nuclear Information System (INIS)

    Five groups of albino male rats, every group consist of seven rats, were used to study the effect of microwave proteins on liver, kidney functions and blood parameters. Control group was fed on 10% casein. The 2nd one was fed on 10% protein from microwave chicken. The 3rd one was fed on 10% protein from boiled chicken. The 4th one was fed on 10% protein from microwave kidney beans. The 5th one was fed on 10% protein from boiled kidney beans. The time of experiment was seven weeks. The biochemical parameters included (cholesterol, LDL, HDL, total lipids, triglyceride, SGOT, SGPT, ALP, creatinin, uric acid and amino acids). The group of rats fed on microwave chicken showed more increase in cholesterol level than the group fed on boiled chicken. The group fed on microwave kidney beans showed decrease in cholesterol level. The group fed on microwave chicken showed decrease in HDL and increase in LDL. The highest activity of SGOT was shown in group fed on microwave kidney beans followed by the group fed on microwave chicken. The groups fed on boiled kidney beans and boiled chicken proteins showed significant increase in SGPT activity. The group fed on boiled kidney beans have the highest activity of ALP enzyme; but the group fed on microwave chicken showed increase in the activity of ALP enzyme compared to the control group. The feeding of microwave chicken leads to increase in creatinine and uric acid levels in comparison to the control group. Microwave cooking leads to little increase in all amino acids in comparison to the control group

    Full Text Available Background: Since liver is a gland which has an important role in drug metabolism, the present study was conducted to evaluate the effect of a single dose and repeated administration of morphine on LFT, blood sugar and fasting insulin resistance index in fructose- fed male rats. Materials and Methods: The experiment was performed on 36 Wistar-Albino male rats, which were divided into a control (A and three tests groups (B, C and D. The control group consumed tap water, but the test groups consumed fructose-enriched water (10%, w/v and received null, single, and repeated doses of morphine, respectively. At the end, animals were anesthetized and blood samples were collected. Liver enzymes, insulin and insulin resistance were measured. Data were analyzed by SPSS-11, using ANOVA and Tukey tests as post hoc test. Results were expressed as mean±SD and Statistical differences were recognized significant by p<0.05. Results: The results showed that all test groups were insulin resistant; alanine aminotransferase (ALT and asparatate aminotransferase (AST activity values in group D significantly increased compared to other groups while its plasma glucose and insulin values showed a significant decrease in comparison to other test groups. Conclusion: It seems that repeated morphine administration can affect liver function test (LFT and fasting Insulin resistance index (FIRI in fructose- fed male rats.

    The influence of protein, isolated from teak (Tectona grandis) seed upon albino rats with respect to some of their serum, liver and intestinal enzymes and liver lipids has been studied. The protein in question contains aspartic acid, threonine, serine, glutamic acid, proline, glycine, alanine, valine, isoleucine, leucine, tyrosine, lysine, phenylalanine, histidine and arginine as determined by amino acid analyser. After feeding experiment an increase in body weight including the liver weight was noted in the test animals due to excess protein in the diet. A marked increase was observed in G.O.T., G.P.T. and total lipid of liver, whereas G.O.T. and G.P.T. of serum were decreased. The observed increased concentration of lipid in liver may be due to excess addition of protein in diet. The overall observation is an indication of probable fatty infiltration in liver of test animals. PMID:4070763

    Albino rats (Sprague-Dawley) of mean weight 100 g were divided into four groups and given for 7 days a balanced diet. They were then placed in metabolic cages for fifteen days and fed diets containing different quantities of casein: 18% (D18), 36% (D36), 50% (D50) and 72% (D72). The levels of total calcium, inorganic phosphorus, alkaline phosphatase activity, total proteins and urea were determined. The urinary and fecal excretion of calcium were determined on specimens of urine and stool collected every two days. The metabolic balance of nitrogen was also estimated. The results show there is not a linear relationship between a high protein diet and plasma protein levels, but a progressive body calcium loss was observed with the increase of casein in the diet, which confirms what other workers have already suggested.

    1979-01-01

    Rubidium shifts between the extracellular fluid and cells were studied in the isolated atria of guinea-pig and albino rat hearts. In the young of both species, rubidium transport from the incubation medium to the cells was much slower than in preparations from adult animals. That implies that the efficiency of membrane mechanisms for the transport of Na+ and K+ ions in the atrial tissue increases during postnatal life. This conclusion is further confirmed by the finding that the intracellular potassium concentration in the atrial tissue of the young of both species is lower, and the intracellular sodium concentration higher, than in adult animals. Conversely, the serum potassium concentration in the young is higher, and the serum sodium concentration lower, than in adult individuals. PMID:157489

Métodos: foram utilizadas 50 ratas albinas prenhes distribuídas ao acaso em cinco grupos: GI - sem nenhum tratamento (controle I); GII - recebeu água (controle II), GIII, GIV e GV [...] foram tratadas, respectivamente, com 2, 6 e 12 mg/kg de peso corporal por dia de domperidona, com doses fracionadas de 4 em 4 horas, por gavagem, sempre em 1 ml de água destilada, desde o dia zero até o 20º dia de prenhez. O ganho de peso das matrizes foi avaliado no dia zero e no 7º, 14º e 20º dia de prenhez, sendo que no 20º dia todos os animais foram sacrificados. A seguir foram anotados os seguintes parâmetros: número de sítios de implantação, de placentas e de fetos, pesos das placentas e dos fetos, malformações e mortalidade materna e fetal. Resultados: considerando as variáveis apreciadas, o fármaco influiu somente sobre a mortalidade fetal, sendo respectivamente de 14, 26 e 32 óbitos intra-uterinos entre 74, 60 e 57 crias, considerando os grupos III, IV e V. Conclusões: embora os resultados da experimentação animal não possam ser diretamente levados para a clínica humana, este trabalho alerta para os cuidados na prescrição de domperidona durante o período gestacional. Abstract in english Purpose: the aim of the present work was to study the chronic action of the antiemetic domperidone on the pregnancy of albino rats. Methods: fifty albino, pregnant Wistar rats were randomly allocated to five groups: GI (control I) = intact rats; GII (control II) = rats receiving the drug vehicle (di [...] stilled water) by gavage at the same schedule of the experimental groups; rats in groups GIII, GIV and GV were treated with domperidone by gavage, 2, 6 and 12 mg/kg per day, respectively, divided into 4 daily doses, always in 1 ml of distilled water, from time zero up to the 20th day of pregnancy. The evolution of body weight gain was followed throughout and the animals were sacrificed at term (20th day) by deep ether anesthesia. Number of fetuses, placenta and implantation sites, placenta and fetus weight, fetal malformations and maternal and fetal mortality were evaluated. Results: we observed only intrauterine fetal mortality with 14, 26 and 32 in 74, 60 and 57 newborns of the groups III, IV and V, respectively. Conclusion: though the results of animal experimentation cannot directly be transposed to human conditions, this paper calls attention to the need for a safe judgement when prescribing domperidone to a first-trimester pregnant patient in order to reduce her emetic crises.

    International Nuclear Information System (INIS)

    This study was conducted to clarify the potential role of lettuce oil against damages induced in rats due to exposure to gamma radiation. Adult male albino rats (120-150 g) were divided into 4 groups each of 12 animals. The first group was considered control animals. The second group received, via gavages, lettuce oil (200 mg/Kg body weight) for 3 weeks. The third group was subjected to a single dose of 6.5Gy whole body gamma irradiation. The fourth group received lettuce oil for 3 weeks then was exposed to radiation. Blood samples were collected 1 and 7 days post irradiation. Exposure of rats to gamma irradiation caused a significant increase in the level of glucose, total cholesterol (TC), triglycerides (TG), malondialdehyde (MDA) and follicle stimulating hormone (FSH) while a significant decrease was recorded in glutathione content (GSH), superoxide dismutase (SOD) and catalase activities, white blood cells (WBCs), red blood cells (RBCs), haemoglobin content (Hb), haematocrit percentage (Hct%), mean corpuscular volume (MCV), platelets (PLT), leutinizing hormone (LH) and testosterone hormone . In rats treated with lettuce oil then exposed to radiation, the results showed an improvement in all previous parameters. It could be concluded that lettuce oil might reduce the biological hazards in rats induced by gamma irradiation

    Full Text Available Abstract Background The current practice of ingesting phytochemicals for supporting the immune system or fighting infections is based on centuries-old tradition. Macrophages are involved at all the stages of an immune response. The present study focuses on the immunostimulant properties of Tinospora cordifolia extract that are exerted on circulating macrophages isolated from CCl4 (0.5 ml/kg body weight intoxicated male albino mice. Methods Apart from damaging the liver system, carbon tetrachloride also inhibits macrophage functions thus, creating an immunocompromised state, as is evident from the present study. Such cell functions include cell morphology, adhesion property, phagocytosis, enzyme release (myeloperoxidase or MPO, nitric oxide (NO release, intracellular survival of ingested bacteria and DNA fragmentation in peritoneal macrophages isolated from these immunocompromised mice. T. cordifolia extract was tested for acute toxicity at the given dose (150 mg/kg body weight by lactate dehydrogenase (LDH assay. Results The number of morphologically altered macrophages was increased in mice exposed to CCl4. Administration of CCl4 (i.p. also reduced the phagocytosis, cell adhesion, MPO release, NO release properties of circulating macrophages of mice. The DNA fragmentation of peritoneal macrophages was observed to be higher in CCl4 intoxicated mice. The bacterial killing capacity of peritoneal macrophages was also adversely affected by CCl4. However oral administration of aqueous fraction of Tinospora cordifolia stem parts at a dose of 40 mg/kg body weight (in vivo in CCl4 exposed mice ameliorated the effect of CCl4, as the percentage of morphologically altered macrophages, phagocytosis activity, cell adhesion, MPO release, NO release, DNA fragmentation and intracellular killing capacity of CCl4 intoxicated peritoneal macrophages came closer to those of the control group. No acute toxicity was identified in oral administration of the aqueous extract of Tinospora cordifolia at a dose of 150 mg/kg body weight. Conclusion From our findings it can be suggested that, polar fractions of Tinospora cordifolia stem parts contain major bioactive compounds, which directly act on peritoneal macrophages and have been found to boost the non-specific host defenses of the immune system. However, the molecular mechanism of this activity of Tinospora cordifolia on immune functions needs to be elucidated.

  1. Effect of Dracocephalum moldavica Extract on Some Biochemical Changes Induced after Whole Body Gamma Irradiation of Male Rats

    International Nuclear Information System (INIS)

    Dracocephalum moldavica (DM); a medicinal plant with antioxidant, antibacterial and antifungal properties, has been cultivated recently in Egypt. The purpose of this study was to investigate its possible protective effect against radiation induced damage in male albino rats. DM total extract was administered by oral gavages to male albino rats at a dose of 40 mg/kg body wt daily for 2 weeks before whole body gamma irradiation with 6 Gy. Exposure of rats to whole body gamma irradiation induced oxidative stress and biochemical disorders in liver and kidney tissues. Oxidative stress was manifested by significant increase of liver and kidney malondialdehyde (MDA) along with the reduction in glutathione (GSH) contents on the 1st, 3rd and 7th day post- irradiation. Biochemical disorders were evidenced by a significant increase in serum creatinine and uric acid levels, transaminases (ALT and AST) activities, and triglycerides level. A significant decrease in total cholesterol was recorded on the 1st day post irradiation followed by a significant increase on the 3rd and 7th day. DM administration pre-irradiation has significantly attenuated radiation- induced oxidative stress in liver and kidney tissues which was associated with significant improvement of the biochemical disorders. It could be concluded that DM extract through its antioxidant properties and the synergistic relationship of its different constituents may protect the liver and kidney tissues from radiation induced oxidative damage associated with biochemical disorders.

    Objectives: The objective of this study was to evaluate the antistress activity of Momordica charantia (MC) fruit extract on stress-induced changes in albino rats and also to explore attenuating effects of MC on in vitro lipid peroxidation in rat brain. Materials and Methods: In this study, Wistar albino rats (180–200 g) were used. Plasma corticosterone and monoamines—5-hydroxy tryptamine (5-HT), norepinephrine (NE), epinephrine (E) and dopamine (DA) in cortex, hypothalamus and hippocampus regions of brain were determined in animals under different stressful conditions. Ethanolic fruit extract of MC, at doses of 200 and 400 mg/kg, was used. The oxidative stress paradigms used in in vivo models were acute stress (AS) and chronic unpredictable stress (CUS). Panax quinquefolium (PQ) was used as a standard in in vivo models and ascorbic acid was used as a reference standard in the in vitro method. Results: Subjecting the animals to AS (immobilization for 150 min once only) resulted in significant elevation of plasma corticosterone levels and brain monoamine levels. Pretreatment with MC at doses of 200 and 400 mg/kg p.o. significantly countered AS-induced changes and a similar effect was exhibited by PQ at 100 mg/kg p.o. In the CUS regimen (different stressors for 7 days), plasma corticosterone levels were significantly elevated whereas the levels of 5-HT, NE, E, and DA were depleted significantly. Pretreatment with MC (200 and 400 mg/kg) attenuated the CUS-induced changes in the levels of above monoamines in cortex, hypothalamus, and hippocampus regions of brain and plasma corticosterone in a dose-dependent manner. Furthermore, MC extract (1000–5000 ?g/mL) exhibited a significant quenching effect on in vitro lipid peroxidation indicating its strong antioxidant activity which was compared with ascorbic acid. Conclusions: This study reveals the antistress activity of MC as it significantly reverted the stress-induced changes, and the activity might be attributed to its antioxidant activity since stress is known to involve several oxidative mechanisms.

    Full Text Available Experimentally induced periodontitis forms the basis for trials of novel drugs and therapeutics. Ketamine, an N- amino-D- aspartate (NMDA receptor antagonist is considered to be safe dissociative anesthetic agent. But, the literature on the use of Ketamine as an effective general anesthetic is conflicting. We had to determine, safe and effective dose range of intra-peritoneal Ketamine hydrochloride injection in Wistar albino rats for the placement of ligatures in the oral cavity. 50 rats of the age group (greater than 4 months and weight of160g-350g were selected for the study from the Department of Pharmacology, Yenepoya University, and Mangalore. Intraperitonial injection was administered using Tuberculin syringe. The optimal dose for each animal was tabulated and log dose was calculated. Nonlinear regression analysis was done. 95% confidence limit and ED50 was calculated from the graph was 101.9mg/kg (68.1-152.6mg/kg correlation coefficient was 0.4946.  Profound and effective anesthesia was obtained at a dose of 60mg/kg-275mg/kg. The dose range of Ketamine alone from 60-275mg/kg i.p.route produced profound reproducible anesthesia. Minor oral surgical procedures could be carried out without discomfort. Mortality and morbidity due to anesthesia was low.

  11. Efficacy of ginger in alleviating the severe radiation-induced biochemical, histological and embryological impactions pregnant female albino rats

    International Nuclear Information System (INIS)

    Ginger (Zingiber officinale), a common part of the diet in many parts of the world, is one of the strongest plant antioxidants that has various pharmacological effects. Accordingly, this study was investigated to clarify the beneficial effect of maternal intake of ginger on radiation-induced maternal and fetal detrimental impacts. Pregnant albino rats were administered ginger tea from gestation day 10 to 14 at a dose rate of 10 ml/kg body weight before being exposed to a single dose of 6 Gy of whole body gamma irradiation at day 15 of gestation, after which they were excised on the 18th day of pregnancy. Maternal ginger pre-treatment before radiation exposure was able to diminish the high levels of malondialdehyde (MDA), glucose, lipids, follicle stimulating hormone (FSH) and luteinizing hormone (LH) recorded in the serum of irradiated mother rats in addition to restoring the histopathological lesions induced in their aorta and uterus tissues. Moreover, ginger intake was found to reduce the severe deleterious symptoms of radiation-induced fetal mortality rate with increased growth in surviving fetuses and remarkable protection against severe morphological deformities.The present study suggests that ginger is an effective agent for improving the affected maternal biochemical and histological studied parameters and reducing the embryonic injuries induced by gamma irradiation

    Heritable oligodactylism in male rats was discovered in Wistar-derived rats. In this study, external and skeletal features of the limb anomalies were examined to clarify the type of oligodactyly. External observation revealed absence and hypoplasia (with respective percentage incidence) in digits II (100, 0), III (87, 13), and IV (23, 1) of the forefeet and in digits II (26, 34), III (34, 11), and V (0, 3) of the hindfeet. Fusion was also observed in digits IV and V in the forefeet (4%) and in digits I and II in the hindfeet (15%). Skeletal examination disclosed absence of all three (proximal, middle, and distal) phalanges in digits II (97%), III (93%), and IV (67%) and of the middle phalanx in digit V (12%) of the forefeet. In the hindfeet, the missing pattern of phalanges in digits II and III was similar to, but less severe than that in the forefeet; the incidence of absence of the three phalanges in digits II and III was 43% and 45%, respectively. Digit V was more affected than that in the forefeet; absence of the middle phalanx was found at 30%. Although no absence was found in the bones proximal to the phalanges, hypoplasia and/or fusion were detected with various degree and incidences among carpi/metacarpi and tarsi/metatarsi. Based on these observations, the types of limb anomalies in this mutant rat were classified as oligodactyly of digits II-V in the forefeet and II, III, and V in the hindfeet with hypoplasia and/or fusion of the carpi/metacarpi and tarsi/metatarsi.

The present study is aimed to investigate the effect of 50% ethanolic extract of clove on general mating behaviour, libido, potency along with its likely gastric ulceration and adverse effects on sexually normal male albino rats. Methods The suspension of the extract was administered orally at the dose of 100, 250, and 500 mg / kg, to different groups of male rats (n = 6 once a day for seven days. The female albino rats involved in mating were made receptive by hormonal treatment. The general mating behaviour, libido and potency were determined and compared with the standard reference drug sildenafil citrate. The probable gastric ulceration and adverse effects of the extract were also evaluated. Results Oral administration of the extract significantly increased the Mounting Frequency, Intromission Frequency; Intromission Latency, Erections; Quick Flips, Long Flips as well as aggregate of penile reflexes and caused significant reduction in the Mounting Latency and Post Ejaculatory Interval. The most appreciable effect of the extract was observed at the dose of 500 mg/kg. The test drug was also found to be devoid of any conspicuous gastric ulceration and adverse effects. Conclusion The results indicated that the 50% ethanolic extract of clove produced a significant and sustained increase in the sexual activity of normal male rats, without any conspicuous gastric ulceration and adverse effects. Thus, the resultant aphrodisiac effectivity of the extract lends support to the claims for its traditional usage in sexual disorders.

    2015-01-01

    The effect of vitamin E intake on spatial learning and working memory performances of young rats has been investigated in the Morris water maze and locomotor activity has been assessed by an open-field test. A total of 45 young male Wistar albino rats aged two months were divided into three equal groups: control, olive oil, and vitamin E groups. These groups were treated for 30 days with a once daily intraperitoneal injection. The rats were then tested for their ability to find the location of the platform (spatial learning). The results revealed that there was no statistically significant difference between the time spent to find the platform and the time spent in half area of the tank, including the platform among the group, while the time spent to find the platform was found to have increased from the first day to the fourth day in all the groups. In the open-field test, the locomotor activity quite significantly increased in the peripheral area in the olive oil group. The supplementation with vitamin E for a short period had not improved the learning performance of the healthy young rats. It was concluded that the beneficial effect of vitamin E intake on learning is related to the beginning time and the duration of vitamin E intake. PMID:26380558

    Full Text Available The effects of the aqueous root extract of urena lobata on the rat liver was investigated using a total of (25 adult Wister rats of both sexes that were randomly divided into five groups of five rats each. Group I served as the control, while rats in groups II-IV where administered 100, 200 and 300 mg/kg body weight of the extract, respectively for 28 days. Rats in group V were administered 300 mg/kg of the extract for 28 days and allowed to stay for 14 days post treatment to observe for reversibility, persistence or delayed occurrence of toxic effects. At the end of the experimental period the animals were sacrificed and liver weight taken and fixed for routine histological examinations. Administration of the extract to rats had no effects on liver and body weights but the extract caused a decrease in albumin level and increases in the levels of Aspartate Transaminases (AST, Alanine Transaminases (ALT and Alkaline Phosphatase (ALP. Histopathological assessment of the liver revealed mild to severe interstitial hemorrhage, mononuclear cell infiltration, necrosis, congestion and edema in the liver of the treated rats while withdrawal of the extract for 14 days showed a slight degree of recovery in the rats. This findings suggest that the biochemical and morphological organization of the liver can significantly be altered with continues and increase use of the extract, but further studies on the long term effect of the extract and a prolonged recovery period is recommended in further studies.

    International Nuclear Information System (INIS)

    The present study was carried out to investigate the effect of low intensity laser irradiation on the antioxidant defense system in testis of rats as indication of laser hazard. The study included 60 Albino rats weighing between 100-120 g, which was divided into five groups as follows: G1: Rats were used as control group. G2: Rat testes were exposed to He-Ne laser. G3: Rats were injected intraperitoneally with 500 mg/kg serotonin (Sigma, USA) dissolved in saline. G4: Rat testes were exposed to He-Ne laser then animals were injected intraperitoneally with 500 mg/kg serotonin. G5: Rats were injected intraperitoneally with 500 mg/kg serotonin then the testes were exposed to He-Ne laser (1J/cm2). The biochemical analyses were performed at one and eight days post-laser irradiation. The results showed significant increase in the level of lipid peroxide product (malondialdehyde) and significant decrease in the antioxidant defense system (glutathione and glutathione peroxidase) after one and eight days post-laser irradiation of rat testis. Following exposure to He-Ne laser, the total lipids and cholesterol were increased in testis tissue. On the other hand, plasma male sex hormone (testosterone) and lactate dehydrogenase were increased. It is advised to use serotonin as a protector before exposure to He-Ne laser

However they had delayed onset and recovery was found to be prolonged. The present study was undertaken with an aim to evaluate the effect of Aegle marmelos bark extract on rats as the extract is found to be a rich source of marmin and fagarine known for reducing male fertility. Three different concentration of methanolic bark extracts of Aegle marmelos (L. were evaluated for male antifertility activity on albino wistar rats. Methanolic bark extract of Aegle marmelos at the dose of 200, 400, and 600 mg/Kg b.w was administered orally for 60 days. Treatments were stopped thereafter and animals were sacrificed after a recovery period of 30 days. Control animal were administered vehicle (0.5% CMC for 60 days. Lonidamine was used as standard drug to compare the effect of extract. Results Methanolic extract causes a dose & duration dependent infertility via reducing reproductive organ weight and serum testosterone levels. Sperm analysis results showed reduction in sperm density, motility, viability and sperm acrosomal integrity without interfering libido and vital organ body weight. Histopathological studies of testes revealed exfoliation of elongated spermatids, nuclear chromatin condensation, degeneration and prominent spaces detected within the germinal epithelium signifying testicular cytotoxicity and necrosis. Time dependent complete infertility was observed in all dose levels. Animals after the withdrawal from treatment, for 30 days showed restoration of the morphological as well as physiological parameters in extract treated rats. Methanolic extract showed lipid lowering activity compared to control, suggestive good candidature of this plant for further studies.

Gastric cancer management is based on the surgery, radiotherapy and chemotherapy. In the present study, for the first time, the beneficial effect of saffron (Crocus sativus L. aqueous extract (SAE on the 1-Methyl-3-nitro-1-nitrosoguanidine (MNNG-induced gastric cancer in rat was investigated. Materials and Methods: MNNG was used to induce gastric cancer and then, different concentrations of SAE were administered to rats. After sacrificing, the stomach tissue was investigated by both pathologist and flow cytometry, and several biochemical parameters was determined in the plasma (or serum and stomach of rats. Results: Pathologic data indicated the induction of cancer at different stages from hyperplasia to adenoma in rats; and the inhibition of cancer progression in the gastric tissue by SAE administration; so that, 20% of cancerous rats treated with higher doses of SAE was completely normal at the end of experiment and there was no rat with adenoma in the SAE treated groups. In addition, the results of the flow cytometry/ propidium iodide staining showed that the apoptosis/proliferation ratio was increased due to the SAE treatment of cancerous rats. Moreover, the significantly increased serum LDH and decreased plasma antioxidant activity due to cancer induction fell backwards after treatment of rats with SAE. But changes in the other parameters (Ca2+, tyrosine kinase activity and carcino-embryonic antigen were not significant. Conclusion: SAE inhibits the progression of gastric cancer in rats, in a dose dependent manner.

  6. Potency of maternal folic acid supplementation on gamma irradiation- induced histological and embryological anomalies in albino rats

    International Nuclear Information System (INIS)

    Folic acid, a member of the water-soluble vitamin B group, is emerged as an important nutritional factor especially during the course of pregnancy. It is rapidly absorbed from the proximal part of small intestine, distributed to the body tissues, stored in the liver and actively concentrated in the cerebrospinal fluid. The objective of this study was to evaluate the potency of maternal folic acid supplementation in ameliorating the maternal and fetal detrimental impacts of gamma irradiation. Folic acid, at a dose level of 4 mg/Kg body weight was daily administered via an oral stomach tube to pregnant adult albino rats from the 1st to the 20 th day of pregnancy, while mothers were subjected to gamma irradiation at the dose of 3 Gy on day 10 of gestation during the sensitive period of organogenesis. Experimental investigations carried out 1 day prior to parturition have demonstrated that folic acid intake throughout the whole gestational period had significantly diminished the deleterious histopathological disorders in large intestine, liver and uterus of irradiated mothers. Concomitantly, folic acid has been able to enfeeble the hazardous teratological effects of radiation including mainly the fetal intrauterine lethality, developmental delay and prominent morphological deformities. Conclusively, folic acid was found to offer protection during pregnancy against radiation injury, thus was capable of modulating the histopathological impacts of the studied maternal body organs and suppressing the embryonic mortality rates and serious fetal malformations induced by radiation

    The pulp of Dacryodes edulis G.Don which is rich in oils is commonly consumed in Nigeria when in season. The effect of diet supplementation with edulis fruit pulp oil on body lipid parameters was evaluated in male Wistar albino rats. D. edulis oil was extracted in n-hexane. The test diet was.compounded using the oil extract (10%), whereas the control animals were kept on control diet formulated with groundnut oil (10%). After six weeks, the animals were anaesthetized with chloroform and blood samples collected through cardiac puncture for the determination of serum lipid profile. Results revealed that D. edulis fruit pulp oil did not cause any significant (p > 0.05) alterations in serum total cholesterol, LDL-cholesterol and triacylglycerol. The total amount of lipids present in the serum was increased by 33.3%, whereas the quantity of liver lipids decreased by the same factor (33.3%). Insignificant (p > 0.05) increases in the weights (g 100 g(-1) BW) of the liver (2.91 ± 0.17 to 3.38 ± 0.25), kidney (0.36 ± 0.06 to 0.40 ± 0.02) and heart (0.32 ± 0.02 to 0.33 ± 0.04) were observed in the test group. No significant change (p > 0.05) in the average body weight of the test animals was recorded. HPLC analysis of D. edulis oil showed that it contained palmitic acid (48.7%), linoleic acid (28.6%),oleic acid (12.9%), stearic acid (5.0%), lauric acid (2.2%), linolenic acid (1.7%) and myristic acid (0.9%). The peroxide value of the oil was 0.00. Prolonged intake of D. edulis fruit pulp oil may induce adverse effects on the body organs, even though the body lipid profile remains unaltered.

    Trigonella foenum graecum is an Iranian medicinal plant used for the treatment of rheumatoid arthritis and inflammation. The present study was designed to investigate the beneficial outcome of the plant T. foenum graecum on adjuvant-induced arthritis in albino rats. Ethanol extract of T. foenum graecum was tested against Freund's complete adjuvant-induced arthritis in rats. In the present study, paw volume was measured on the 4th, 8th, 14th and 21st day. On day 22, animals were anaesthetized, and blood samples were collected for the estimation of haemoglobin, white blood cells (WBC), differential white blood cells, erythrocyte sedimentation rate (ESR), red blood cells (RBC), interleukins (IL-1?, IL-1?, IL-2, IL-6) and tumour necrosis factor-? (TNF-?). The animals were sacrificed, and the cartilage tissue was isolated for estimation of lipid peroxidation (LPO), superoxide dismutase (SOD) and glutathione (GSH). Administration with both doses of T. foenum graecum (200 and 400 mg/kg) significantly (P < 0.05) decreased the paw oedema and restored body weight. T. foenum graecum significantly (P < 0.05) reduced the differential WBC count, ESR and WBC (5.833 ± 0.703, 6.989 ± 58.5) content and also showed significant (P < 0.05) increase in RBC and Hb (4.783 ± 0.46, 15.46 ± 0.158) content. T. foenum graecum significantly (P < 0.05) decreased the IL-1?, IL-1?, IL-2, IL-6 and TNF-? levels. It also significantly decreased the levels of LPO and increased the SOD and GSH levels in cartilage tissue. In this study, T. foenum graecum 400-mg/kg dose showed more prominent results compared to the 200-mg/kg dose of T. foenum graecum. The results obtained in this study suggest that anti-inflammatory and antioxidant activities of T. foenum graecum may be the possible reason behind the observed anti-arthritic activity.

    Full Text Available Objective: N-nitroso-N-methylurea (NMU induces breast cancer in rodents, particularly in rats. This model of breast cancer is very similar to human breast cancer. As a continuation of our recent work, we investigated the expressions of cyclin D1 and p21 in NMU-induced breast cancer of Wistar Albino rats.Materials and Methods: In this experimental study, mammary carcinoma was induced in female Wistar Albino rats by a new protocol which included the intraperitoneal injection of NMU (50 mg/kg at 50, 65, and 80 days of the animal’s age. The animals were weighed weekly and palpated in order to record the numbers, location, and size of tumors. Subsequently tumor incidence (TI, latency period (LP, and tumor multiplicity (TM were reported. About four weeks after the tumor size reached 1.5 cm3, rats were sacrificed. Cyclin D1 and p21 expressions in tumors and normal mammary glands from normal rats were measured by reverse-transcription polymerase chain reaction (RT- PCR and Western blot analysis. Statistical analysis of the data was performed using SPSS software version 16.0.Results: The efficiency of tumor induction was 65%, LP was 150 days, and a TM of 1.43 ± 0.53 per rat was noted. RT-PCR and Western blot data indicated significant (p<0.05 induction of both cyclin D1 and p21 expressions in rat mammary tumors compared with normal tissue from the control group.Conclusion: These results indicate an efficient mammary tumor induction protocol for this type of rat, which is accompanied by an increase in cyclin D1 and p21 expressions.

    Full Text Available Back ground Toxic heavy metals in water, air and soil are global problems that are a growing threat to humanity. Heavy metals are widely distributed in the environment and some of them occur in food, water, air and tissues even in the absence of occupational exposure. The antioxidant and protective influences of curcumin on a mixture of some heavy metals (Pb, Hg and Cd induced renal and testicular injuries in male rats were detected. Curcumin, a yellow pigment from Curcuma longa, is a major component of turmeric and is commonly used as a spice and food-coloring material. It exhibits anti-inflammatory, anti-tumor, and antioxidant properties. Aim The present study aims to evaluate the antioxidative activities and protective role of curcumin against some heavy metals induced renal and testicular injuries in male rats. Material and Method Male Swiss albino rats were orally administrated by curcumin (150 mg/kg B.W. using suitable stomach tube (eight weeks before receiving mixture of heavy metals (Pd, Hg and Cd in drinking water for two weeks. Levels of plasma creatinine, urea, uric acid and serum testosterone concentration were measured, glutathione content and superoxide dismutase activities in kidney and testis tissues were estimated and also histological examinations for kidney and testis tissue were detected. Results The results revealed that mixture of heavy metals lead to significant increase in the level of plasma creatinine, urea and uric acid, Meanwhile, significant decrease in serum testosterone concentration. Glutathione content and superoxide dismutase activities in kidney and testis tissues were significantly decrease by using a mixture of heavy metals. But groups administrated with curcumin before administrated with mixture of heavy metals, exerted noticeable amelioration against their damage in most of the biochemical and histological tested parameters.

    Full Text Available The present work was undertaken to study the comparative phytochemical profiles and hypoglycemic effects of Bauhinia purpurea Linn. Barks (BPBE and leaves ethanolic extracts (BPLE in albino wistar rats to validate their ethno medical use in hyperglycemia as well as to explore the better option. Phytochemicals in ethanolic extracts were analyzed by standard natural product chemistry methods. Diabetes was developed in rats by single intraperitoneal injection of Streptozotocin @ 60mg/ Kg bw. Diabetic albino wister rats (n=3 of either sex (150-200gm bw were orally fed with the extracts once daily for 4 weeks. Glibenclamide @ 0.5mg/Kg bw was used as a positive control for comparison. Fasting blood glucose level at 0, 14th and 28th day and hemoglobin and glycosylated hemoglobin on 28th day of experiment were analyzed. Our results show that the extracts contain alkaloids, flavonoids, glycosides, terpenoids, tannins and phenolics. Rats treated with plant extracts show better glucose modulation, decreased hemoglobin glycosylation and improved hemoglobin concentration as compared to diabetic control. The hypoglycemic effect of only BPBE at 420 mgkg-1 on 14th and 28th day is comparable to that of standard drug glibenclamide (P>0.01. The bark extract has been observed to be more potent hypoglycemic agent than leave extract.

  1. Low-Dose Aspirin Treatment Alleviates Gamma Irradiation Impaired Fertility in Female Albino Rats

    International Nuclear Information System (INIS)

    Recent experimental evidence suggests that Aspirin (acetylsalicylic acid), the extensively prescribed analgesic, can improve female fertility by suppressing the prostaglandin (PG) biosynthesis and modulating the uterine circulation. Aspirin has also been found to exhibit a protective ability on the radiation induced oxidative stress. Thus the present work aims to investigate the effect of oral low-dose Aspirin treatment on the radiation induced female reproductive disturbance. Adult female rats were used in the current experiment. All rat group treatments started at the onset of the proestrus phase and terminated at the diestrus encompassing 2 complete estrus cycles. Subsequently, the rats were divided into 4 equal groups: Group 1-Control: female rats receiving distilled water via an oral gavage; Group 2- Irradiation: female rats subjected to 6 Gy gamma rays at the proestrus cycle and receiving distilled water; Group 3-Aspirin: rats orally administered a daily dose of 7mg/kg body weight aspirin dissolved in distilled water via an oral gavage and Group 4- Irradiation + Aspirin: female rats irradiated as group 2 and receiving aspirin treatment. A number of rats from each experimental group were allowed to mate following every treatment to serve as Control mated (Subgroup 1), Irradiated mated (Subgroup 2), Aspirin administered mated (Subgroup 3) and Irradiated + Aspirin treated mated (Subgroup 4). At the assigned day of the second estrus cycle completion, blood was collected from Groups 1-4 for subsequent hormonal assay, lipid peroxides and glutathione (GSH) estimation whereas Subgroups 1-4 were carefully monitored for reproduction and infertility rates. Results have shown that the 6 Gy ?- irradiation of the rats at the proestrus cycle (Group 2) caused a decrease in follicle stimulating hormone (FSH), luteinizing hormone (LH), prolactin (PRL) and estradiol (E2) levels associated with a drastic increase in the progesterone levels in addition to the significant elevated malondialdehyde (MDA) and reduced glutathione (GSH) levels compared to the related serum control values. The radiation effect was extended to Subgroup 2 that revealed apparent infertility. Moreover, Aspirin oral daily administration caused a remarkable reduction in both FSH and LH hormones alongside with elevated progesterone and PRL levels with no noted E2 level changes (Group 3). However the same treatment accelerated both the fertility and re productivity rates of Subgroup 3. However, the results of the present study revealed the potency of the anti-inflammatory drug Aspirin when administered post radiation exposure (Group 4) in ameliorating the abrupt irradiation induced hormonal imbalance and the significant elevation in serum MDA in addition to its ability in alleviating the radiation induced reproductive disorders (Subgroup 4). In conclusion, oxidative stress caused by radiation exposure of cycling female rats induced marked disturbance in their hormonal balance leading to negative fertility outcomes that has been ameliorated by Aspirin therapy.

    Full Text Available Thirty two adult female albino rats were randomized into 2 main groups (control and experimental. The control group (n=8 received IM injection of 0.3 ml of the drug vehicle (castor oil & benzyl benzoate once every 5 days for 6 times. 50% of rats of this group were scarificed after 24 hours of the last injection while the other 50% were left for 15 days. Experimental group was divided into 2; experimental group 1; E1 (n=12 received IM injection of 1.5 mg/kg BW of the drug (Mesigyna, once every 5 days for 6 times, and were sacrificed 24 hours after the last injection. Experimental group 2; E2 (n=12 were injected as in group E1 then left for 15 days. Uterine tissue was used for various techniques; histological (H&E & Masson's trichrome and immunohistochemical (staining of progesterone receptors, using Labeled-Streptavidin method. Both qualitative and quantitative analyses were done to assess the degree of uterine affection. Quantitative measurements (optical density, color area percentage, line distance & cells count were performed using the image analyzer. Mesigyna injection showed increased endometrial folding (91.6% of the animals with decreased endometrial thickness. Luminal epithelium showed proliferation with pseudostratification of its nuclei (75% of animals, necrotic changes (31.3% of animals, hyperplasia (epithelial tufting; in 25% of animals and desquamation (8.3%of animals. Increased gland size and stromal hypercellularity were also observed. Polymorphonuclear cellular infiltration in both endometrium and myometrium, Vascular congestion and increased myometrial thickness were respectively seen in 83.33%, 63.5 %, 83.5% of E1 group animals. Mesigyna also caused reduction in the amount of collagen fibers. Immunostaining revealed decreased number and optical density of progesterone receptors in nuclei of surface epithelium, glandular epithelium and stromal cells while they were increased in nuclei of smooth muscle fibers. Image analysis results confirmed both the histological and the immunohistochemical results. After withdrawal of the drug (group E2, results showed reduction in necrotic changes, endometrial folding, epithelial tufting and hyperplasia. However there was an aggravation of Polymorphonuclear infiltration, vascular congestion and immunohistochemical changes which indicated delayed recovery of these changes in rat uterus under the effect of Mesigyna. In conclusion Mesigyna was found to produce severe histopathological changes which were not completely recovered after 15 days of drug stoppage.

    International Nuclear Information System (INIS)

    The objective of this study is to illustrate the radiomodulatory role of melatonin in the regulation of some biochemical and histopathological damage in case of total body irradiated rats.Male albino rats weighing 120-150 g were divided into four groups, group (I) control animals, group (II) animals received melatonin daily by gavages (3 mg/kg body weight) for two weeks, group (III) animals irradiated with 4 Gy Gamma rays and group (IV) animals irradiated with 4 Gy Gamma rays followed by daily administration with melatonin (3 mg/kg body weight) for two weeks. Rats were sacrificed on the 1st and 2nd week post-irradiation. Blood samples were collected for biochemical investigations. The activities of aspartate aminotransferase (AST), alanine aminotransferase (ALT) and alkaline phosphatase (ALP), were determined as biomarkers of liver functions, urea and creatinine contents were measured as markers of kidney functions, creatine phosphokinase (CPK) and lactate dehydrogenase (LDH) activities were selected to evaluate heart damage. Alteration in the level of serum glucose was also determined. Tissue specimens from liver, kidney, heart and spleen were collected for the pathological studies.The results indicated that, the levels of liver enzymes, kidney functions and glucose were increased after irradiation of rats and reduced by the treatment with melatonin. These reductions were more noticed during the second weeks except in case of glucose which increased during the second week compared to the first week. On the other hand, heart enzymes levels were reduced by the effect melatonin which may be important for cardiopathological patients.Histopathological results showed that irradiation of rats induced tissue injuries in liver, kidney, heart and spleen.Melatonin treatment reduced these injuries to minimum.It could be concluded that, melatonin could be used as antioxidant to protect vital organs and their functions against irradiation since it works as free radicals scavenger

    Adenosine (Ado) and non-adenosine (non-Ado) nucleosides such as inosine (Ino), guanosine (Guo) and uridine (Urd) may have regionally different roles in the regulation of physiological and pathophysiological processes in the central nervous system (CNS) such as epilepsy. It was demonstrated previously that Ino and Guo decreased quinolinic acid (QA)-induced seizures and Urd reduced penicillin-, bicuculline- and pentylenetetrazole (PTZ)-induced seizures. It has also been demonstrated that Ino and Urd may exert their effects through GABAergic system by altering the function of GABA(A) type of gamma-aminobutyric acid receptors (GABAA receptors) whereas Guo decreases glutamate-induced excitability through glutamatergic system, which systems (GABAergic and glutamatergic) are involved in pathomechanisms of absence epilepsy. Thus, we hypothesized that Ino and Guo, similarly to the previously described effect of Urd, might also decrease absence epileptic activity. We investigated in the present study whether intraperitoneal (i.p.) application of Ino (500 and 1000mg/kg), Guo (20 and 50mg/kg), Urd (500 and 1000mg/kg), GABA(A) receptor agonist muscimol (1 and 3mg/kg), GABA(A) receptor antagonist bicuculline (2 and 4mg/kg), non-selective Ado receptor antagonist theophylline (5 and 10mg/kg) and non-competitive N-methyl-d-aspartate (NMDA) receptor antagonist (+)-5-methyl-10,11-dihydro-5H-dibenzo (a,d) cyclohepten-5,10-imine maleate (MK-801, 0.0625 and 0.1250mg/kg) alone and in combination have modulatory effects on absence epileptic activity in Wistar Albino Glaxo Rijswijk (WAG/Rij) rats. We found that Guo decreased the number of spike-wave discharges (SWDs) whereas Ino increased it dose-dependently. We strengthened that Urd can decrease absence epileptic activity. Our results suggest that Guo, Urd and their analogs could be potentially effective drugs for treatment of human absence epilepsy. PMID:26037802

    Our knowledge about the radioprotective effects of melatonin against X-ray-induced skin damage is still lacking. To examine these effects, an animal model of 60 Albino rats was used. The animals were divided into five groups: Group 1, nonirradiated; Group 2, X-ray irradiated (XRI, 8 Gy); Group 3, XRI pretreated with solvent (ethanol and phosphate-buffered saline); Group 4, nonirradiated group treated with melatonin; and Group 5, XRI pretreated with melatonin. The skin was evaluated for ultrastructural changes using transmission electron microscopy (TEM). When compared to the nonirradiated skin (Groups 1 and 4), XRI skin (Groups 2 and 3) showed features of both cell injury and increased metabolic activity. The former included changes such as condensation of the nuclei, vacuolization of the cytoplasm, dilatation of the rough endoplasmic reticulum, swelling of the mitochondria with cristolysis, destruction of the ribosomes and intermediate filaments, fragmentation of the keratohyaline granules and loss of the irregularity of the basal cell borders. The central cells of the sebaceous gland alveoli had larger irregular nuclei and few lipid droplets in their cytoplasm. The hair follicle cells had heterochromatic nuclei and less electron dense cytoplasm containing few complements of the organelles. The features of increased metabolic activity included increased euchromatin, irregularity of the nuclear membrane and increased branching of the melanocytes. Also, an increased number of the Birbeck granules were seen in the Langerhans cells. When compared to the irradiated skin (Groups 2 and 3), these changes were mild or absent in the skin of XRI animals pretreated with melatonin (Group 5). The ability of melatonin to minimize the injurious effects of XRI suggests a radioprotective role. The clinical ramifications of these observations warrant further studies. PMID:15676032

    The effect of Kombucha tea (KT) on oxidative stress induced changes in rats subjected to chromate treatment are reported. KT feeding alone did not show any significant change in malondialdehyde (MDA) and reduced glutathione (GSH) levels, but did enhance humoral response and delayed type of hypersensitivity (DTH) response appreciably over control animals. Chromate treatment significantly enhanced plasma and tissue MDA levels, decreased DTH response considerably, enhanced glutathione peroxidase and catalase activities; however, no change in GSH, superoxide dismutase and antibody titres was noticed. KT feeding completely reversed the chromate-induced changes. These results show that Kombucha tea has potent anti-oxidant and immunopotentiating activities. PMID:10904168

    Full Text Available Summary. The effect of ethyl-acetate fraction of Hibiscus sabdariffa l. seed on pituitary prolactin and milk production was evaluated in albino rats. Twenty four lactating rats were randomly grouped at parturition into control, metoclopramide-treated and Ethyl-acetate-treated group consist of six rats in each group (n=6. The lactating rats were administered control (normal saline, metoclopramide (5mg/kg and ethyl-acetate fraction (100 and 200mg/kg respectively from day 3-17 of lactation. Milk yield for rats were estimated by pup weight and weight gain. The animals were then euthanized on the day 18 and pituitary prolactin was analyzed using prolactin kit. The prolactin level of ethyl-acetate fraction of Hibiscus sabdariffa showed a significant increase (P<0.01 when compared to control group. Pup weight gain was also significantly higher (P<0.05 than the control group. This can be inferred that ethyl-acetate fraction of Hibiscus sabdariffa l. seed has lactogenic activity because it increases pituitary prolactin level and milk production in lactating female albino rats. The LD50 of Ethyl-acetate fraction Hibiscus sabdariffa l. was found to be above 5000mg/kg. Industrial relevance. The outstanding advantage of this galactagogue option is that, it is safer, affordable and tolerable, and it is taken as an alternative in preference to anti-psychotic drugs that have side effect of drowsiness and depression. The plant calyces, leaves and seeds are eaten as foods because it contain substantial amount of essential fatty, Tocopherol (Vitamin E, ascorbic acid (Vitamin C, mineral salts calcium, magnesium, sodium, potassium and phosphorus.

Therefore, the present work was designed to study the effect of exposure in male albino rats to electromagnetic radiations(EMR), produced from a cellular tower for mobile telephone, on some redox elements (copper, iron, zinc and manganese), hepatic glutathione (GSH) and glutathione peroxidase (GSH-PX) in addition to the stress hormone ACTH (adrenocorticotrophic hormone), serum total proteins and total lipids with evaluation of the possible protective role of the antioxidant Glutathione Enhancer. The rats were arranged into three groups: the control unexposed, the exposed untreated and the exposed treated groups. Both exposed groups were subjected to electromagnetic field at frequency of 900-930 MHz, for 24 h/day for 8 weeks, at the same time the third exposed group was supplied with oral injection of the antioxidant three times/week. Results showed that serum levels of zinc, copper, iron and hepatic tissue contents of reduced glutathione and glutathione peroxidase activity and serum total proteins were reduced while serum level of ACTH and manganese were increased in the exposed group compared to control unexposed. Most data of the studied parameters showed improvement after treatment supporting the suggestive protective role of Glutathione Enhancer against the effect of EMR emitted by mobile base station

    Full Text Available Background: Areca nut (Areca catechu Linn. is commonly used for skin ulcers in Indian traditional medicine. Areca nut oil is prepared and is applied topically for burn wound healing. However, scientific study has not been conducted so far. Hence, this study was aimed to evaluate burn wound healing activity of Areca catechu. Objective: To evaluate the burn wound healing property of Areca catechu kernel in normal as well as dexamethasone treated rats.Materials and Methods: Ethanolic extract of Areca catechu kernel was prepared and an ointment was made with 2% of this extract. Burn wound was induced by standard procedure. Rats with burn wound model received either vehicle, standard drug or test drug. Two other groups were injected with dexamethasone to delay the wound healing process. The dexamethasone treated groups received either vehicle or test drug topically. Wound contraction rate and period of epithelialization were measured. The collected data were subjected to statistical analysis. Results: The wound contraction rate was significantly increased in Areca catechu treated group in all the days compared to control. Period of epithelialization was faster in the drug treated group than control group. The dexamethasone treated group showed a significant delay in wound healing process when compared to control. Test drug showed a significant reversal in wound contraction rate and epithelialization period in dexamethasone suppressed burn wound healing model.Conclusion: This study has shown the wound healing property of Areca catechu. Further study is required to know the compounds responsible for its wound healing property and to understand the mechanism of action.

    Full Text Available Ethnopharmacological relevance:Elaeis guineensisJacq (Arecaceae is one of the plants that are central to the lives of traditional societies in West Africa. It has been reported as a traditional folkloric medicine for a variety of ailments. The plant leaves are also used in some parts of Africa for wound healing, but there are no scientific reports on any wound healing activity of the plant. Aim of the study:To investigate the effects of E. guineensis leaf on wound healing activity in rats. Methods: A phytochemical screening was done to determine the major phytochemicals in the extract. The antimicrobial activity of the extract was examined using the disk diffusion technique and broth dilution method. The wound healing activity of leaves of E. guineensiswas studied by incorporating the methanolic extract in yellow soft paraffin in concentration of 10% (w/w. Wound healing activity was studied by determining the percentage of wound closure, microbial examination of granulated skin tissue and histological analysis in the control and extract treated groups. Results: Phytochemical screening reveals the presence of tannins, alkaloids, steroids, saponins, terpenoids, and flavonoids in the extract. The extract showed significant activity against Candida albicans with an MIC value of 6.25 mg/mL. The results show that the E. guineensis extract has potent wound healing capacity, as evident from better wound closure, improved tissue regeneration at the wound site, and supporting histopathological parameters pertaining to wound healing. Assessment of granulation tissue every fourth day showed a significant reduction in microbial count. Conclusions: E. guineensis accelerated wound healing in rats, thus supporting this traditional use.

    Full Text Available Aqueous extract of Spondias mombin in different dilutions was employed to assess its impact on male reproductive, haematologic and biochemical indices of male albino rats. A single daily intragastric administration of 8.4, 16.8 and 33.6 mg kg-1 b.w day-1 of the extract for four weeks did not cause any adverse effect on body and organ weights except the weight of the liver that showed a slight increase. There was a marked dose-dependent reduction (p<0.05 in epididymal sperm progressive motility, sperm count, viability (live/dead ratio and a dose-dependent increase (p<0.05 in percentage abnormal spermatozoa. Abnormalities like double heads, double tails, detached heads and broken tails were frequently observed. Epididymal ?-glucosidase activity was significantly reduced (p<0.05. However, prostatic acid phosphatase activity and citric acid levels and seminal fructose concentrations remained unchanged following Spondias mombin treatment. Blood analysis showed that red cell and white cell counts and haematocrit (Hct levels were in the normal range. Bilirubin, serum glutamate pyruvate transaminase (SGPT, serum glutamate oxaloacetate transaminase (SGOT, urea and protein concentrations were slightly altered by the extract of Spondias mombin. Discontinuation of the extract resulted in full recovery within four weeks of treatment cessation. The results suggest that aqueous extract of the bark of Spondias mombin has reversible antifertility action, the testis and the epididymis probably being the prime sites of action.

    Full Text Available As folhas de Moringa oleifera Lam., Moringaceae, são usados na medicina natural da Índia como um agente hipolipemiante em pacientes obesos. Ratos albinos Wistar foram alimentados com extrato metanólico de M. oleifera (150, 300 e 600 mg/kg, p.o.) e sinvastatina (4 mg/kg, p.o.), juntamente com dieta h [...] iperlipídica por 30 dias. Moringa oleifera e sinvastatina reduziram o colesterol, triacilglicerídeoss, VLDL, LDL e índice aterogênico, mas não aumentaram o HDL em comparação com o grupo controle, com dieta rica em colesterol. O mecanismo de ação do extrato metanólico de Moringa oleifera foi também investigado estimando atividade de HMG CO-A redutase. Moringa oleifera aumentou a excreção fecal de colesterol. Assim, o estudo demonstra que a M. oleifera parece ter efeito hipolipemiante. Abstract in english The leaves of Moringa oleifera Lam., Moringaceae, are used by the Indians in their herbal medicine as a hypolipidemic agent in obese patients. Albino Wistar rats were fed with methanolic extract of M. oleifera (150, 300 and 600 mg/kg, p.o.) and simvastatin (4 mg/kg, p.o.) along with hyperlipidemic d [...] iet for 30 days. Moringa oleifera and simvastatin were found to lower the serum cholesterol, triacylglyceride, VLDL, LDL, and atherogenic index, but were found to increase the HDL as compared to the corresponding high fed cholesterol diet group (control). The Moringa oleifera methanolic extract was also investigated for its mechanism of action by estimating HMG CO-A reductase activity. Moringa oleifera was found to increase the excretion of fecal cholesterol. Thus, the study demonstrates that M. oleifera possesses a hypolipidemic effect.

  13. Activation of cell division and nucleic acid synthesis in the corneal epithelium of albino rats by repeated stress

    International Nuclear Information System (INIS)

    Adaption to unfavorable factors is accompanied by activation of nucleic acid and protein synthesis in systems responsible for adaption. The authors investigate the possibility of similar changes taking place in structures not actively participating in adaptation. The corneas of the dead male albin rats were preincubated with tritium-uridine for 1.5 hours. The mitotic index, the index of tritium-thymidine-labeled nuclei and the intensity of thymidine labeling were determined. The results indicate that after a single exposure to hypoxia, hyperthermia, and immobilization, mitotic index in the corneal epithelium decreased and DNA synthesis under these circumstances remained stable

    Full Text Available Liver toxicity is a major health problem of worldwide proportions. Herbal medicines derived from plant extracts are being increasingly utilized to treat a wide variety of clinical diseases. In the present study, LIV-first (16.3 mg/kg, p.o. was used to screen the hepatoprotective activity. Hepatotoxicity was induced in experimental animals by administration of carbon tetrachloride (CCl 4 (1 ml/kg, i.p. Silymarin (25 mg/kg,p.o. was used as the standard. Biochemical parameters like serum glutamate oxaloacetate transaminase (SGOT, serum glutamate pyruvate transaminase (SGPT, alkaline phosphatase (ALP and serum bilirubin were measured. Cytotoxicity of CCl 4 was estimated by quantitating the release of malondialdehyde. The activity of tissue antioxidant enzymes namely superoxide dismutase, catalase and the level of total protein and glutathione were also measured. Histopathological evaluation of liver sections was also done. CCl 4 administration in rats elevated the levels of SGPT, SGOT, ALP and bilirubin. Administration of LIV-first significantly ( P< 0.01 prevented this increase. The activity of anti-oxidant enzymes in carbon tetrachloride CCl 4 -treated group was decreased and these enzyme levels were significantly ( P< 0.05 increased in LIV-first-treated groups. Histopathological studies revealed that the concurrent administration of CCl 4 with the extract exhibited protection of the liver tissue, which further evidenced the above results. The study confirmed the hepatoprotective activity of LIV-first, which may be attributed to its antioxidant property.

    2003-07-01

    The effects of abamectin pesticide on fertility of adult male Sprague-Dawley rats were investigated. Adult male rats were exposed to tap water containing 0, 571, 857, or 1714 ppm abamectin for 6 weeks. Based on fluid consumption, animals received 0, 1.19, 1.87, and 2.13 mg/animal/day abamectin, respectively. Fertility was significantly reduced in male rats ingesting abamectin at all three doses in that the number of females impregnated by them was significantly reduced. The number of viable fetuses was significantly reduced in females mated with males that ingested abamectin at 1.87 or 2.13 mg/animal/day. Significant increases in the total number of resorptions and the number of females with resorptions were observed in females mated with the exposed males at all three concentrations. The body weight gain and water consumption were significantly lower in males that ingested 2.13 mg/animal/day abamectin. Likewise, ingestion of abamectin at all three concentrations caused a significant increase in the weight of testes. Epididymal and testicular sperm counts and daily sperm production were significantly decreased in exposed males. The serum level of testosterone was significantly reduced, whereas the serum level of follicle-stimulating hormone was significantly increased in males that ingested abamectin at a concentration of 2.13 mg/animal/day. Histological evaluation of the testes revealed several abnormalities including infiltration with congested blood vessels with marked hemorrhage and a significant accumulation of connective tissue surrounding the seminiferous tubules. These results strongly suggest the adverse effects of abamectin pesticide on male rat fertility. PMID:12798765

    Full Text Available Objective: We investigated hepatoprotective and antioxidant activity of extracted anthocyanins fraction of red radish for the first time. Methods: Anthocyanins fraction of red radish (Raphanus sativus; AFRS was selectively extracted by employment of polymeric ion-exchange resin. AFRS was evaluated for antioxidant and hepatoprotective activity against carbon tetrachloride (CCl4-induced hepatotoxicity in rats. The animals were divided into seven groups of six animals each. Group I (control received vehicle. Group II (drug control received AFRS. Group III (toxicant received CCl4. Group IV, V and VI received AFRS at doses of 50, 100 and 150 mg/kg po, respectively. Group VII (standard received silymarin. Various biochemical parameters like alanine aminotransferase (ALT, aspartate aminotransferase (AST, alkaline phosphatase (ALP, total bilirubin (TB and direct bilirubin (DB levels in serum as well as the glutathione (GSH and malondialdehyde (MDA levels in the liver were determined. Histopathological changes in the liver were also studied. The activity of AFRS was compared with the reference drug silymarin. Results: The yield of AFRS was found to be 0.084% (w/w. AFRS treated group did not show any significant change in the activity of serum ALT, AST, ALP, TB, DB, MDA and GSH level compared to control group. CCl4 significantly raised the serum level of all biochemical parameters (except GSH in the toxicant group. The pre-treatment of AFRS for seven days had reversed the alteration of biochemical parameters towards normal, and the effects were comparable to standard drug (silymarin 100 mg/kg. The animals received pre-treatment of AFRS showed amelioration in necrotic zones and hepatocellular degeneration. Conclusion: This study demonstrates the antioxidant and hepatoprotective activity of anthocyanins fraction isolated from Raphanus sativus and thus scientifically supports the usage of it as food colorant and also justifies the use of the crude extracts of radish to treat various liver ailments in Indian folk medicine.

    It is well established that female rats are more sensitive than male rats to the reinforcing effects of cocaine (Lynch, 2008 for review). We hypothesized that greater preference for cocaine would support greater avoidance of a cocaine-paired taste cue in female vs. male rats. Moreover, at least in male rats, greater avoidance of the taste cue is associated with greater cocaine self-administration (Grigson & Twining, 2002). Thus, we anticipated that female rats would not only demonstrate great...

    Full Text Available Misuse and abuse of the non-steroidal anti-inflammatory and analgesic mefenamic acid among pregnant women in developing coutries constitute a matter of medical concern, mainly as a function of the potentially serious side effects of that drug, notably at the digestive system level. Female rats were treated during the entire pregnancy period (from day 0 up to day 20 with 5, 15, or 45 mg/kg of mefenamic acid (MA once daily, by gavage. Controls received the drug vehicle. We observed that there was a slight yet significant impairment of maternal body weight gain of the animals treated with the two highest doses of MA. Although the drug was proven to exert deleterious effects on kidney and liver metabolic functions, no gross signs of renal or hepatic toxicity were detected in our animals and in their concepts. The digestive effects would be presumably caused by the inhibitory actions of MA on the luminal fluid movement and are accounted for by the observed body weight loss during pregnancy.En los países del tercer mundo, el uso indiscriminado durante el embarazo del fármaco antiinflamatorio no-esteroide, ácido mefenámico, es un tema de preocupación, fundamentalmente, porque este fármaco posee efectos colaterales potencialmente graves, principalmente, a nivel del aparato digestivo. En este trabajo, ratas hembras fueron tratadas durante toda la preñez (desde el día 0 hasta el día 20 de la gestación con 5, 15 o 45 mg/kg de ácido mefenámico (AM, una vez al día. Los controles recibieron el vehículo de la droga. Se observó una discreta, aunque significativa, disminución del ritmo de aumento del peso de las madres tratadas con las dos dosis más altas (15 y 45 mg/kg AM.

    Full Text Available En los países del tercer mundo, el uso indiscriminado durante el embarazo del fármaco antiinflamatorio no-esteroide, ácido mefenámico, es un tema de preocupación, fundamentalmente, porque este fármaco posee efectos colaterales potencialmente graves, principalmente, a nivel del aparato digestivo. En [...] este trabajo, ratas hembras fueron tratadas durante toda la preñez (desde el día 0 hasta el día 20 de la gestación) con 5, 15 o 45 mg/kg de ácido mefenámico (AM), una vez al día. Los controles recibieron el vehículo de la droga. Se observó una discreta, aunque significativa, disminución del ritmo de aumento del peso de las madres tratadas con las dos dosis más altas (15 y 45 mg/kg AM). Si bien hay relatos de que el fármaco puede producir efectos adversos importantes sobre funciones metabólicas hepáticas y renales, no hemos observado señales de toxicidad sobre el hígado o los riñones, tanto de las madres como de sus crías. Los efectos digestivos del AM son inhibición del movimiento del fluído luminal para fuera de la luz del tubo digestivo y por ende, aumento del tránsito intestinal, lo que podría responder por la pérdida de peso corporal materno observada, principalmente, durante el último tercio de la preñez Abstract in english Misuse and abuse of the non-steroidal anti-inflammatory and analgesic mefenamic acid among pregnant women in developing coutries constitute a matter of medical concern, mainly as a function of the potentially serious side effects of that drug, notably at the digestive system level. Female rats were [...] treated during the entire pregnancy period (from day 0 up to day 20) with 5, 15, or 45 mg/kg of mefenamic acid (MA) once daily, by gavage. Controls received the drug vehicle. We observed that there was a slight yet significant impairment of maternal body weight gain of the animals treated with the two highest doses of MA. Although the drug was proven to exert deleterious effects on kidney and liver metabolic functions, no gross signs of renal or hepatic toxicity were detected in our animals and in their concepts. The digestive effects would be presumably caused by the inhibitory actions of MA on the luminal fluid movement and are accounted for by the observed body weight loss during pregnancy.

  7. Alterations in thyroid hormones, lipid peroxidation, glutathione content and protein plasma levels of male rats and their male offspring treated with lead acetate

    International Nuclear Information System (INIS)

    Lead is a pervasive environmental pollutant known to induced a broad range of physiological, biochemical and behavioral dysfunction in both laboratory animals as well as in human. The present work was directed to study the impact of lead (Pb) contamination on blood levels of thyroid hormones. Lipid peroxidation, glutathione content, total protein, albumin and globulin in male albino rats and whether this impact extends to their offspring growing up in same conditions. Animals were classified into three main groups; 1- control. 2- painter's (fathers). 3- first generation of male rats yielded from Pb-contaminated parents (fathers and mothers). groups 2 and 3 were levels; 100 and 200 mg l, drinking water with lead acetates at two dose levels; 100 and 200 mg l. drinking water for two months. The results revealed that lead contamination induced significant elevations (P4) and triiodothyronine (T3) in both fathers and offspring. Yet, lead significantly increase the plasma lipid peroxidation (P<0.001) with concomitant decreased in glutathione blood content in both fathers and male offspring. The plasma levels of total; protein were significantly increased as a response to the plasma albumin elevations and in turn the albumin / globulin ratio in both fathers and male offspring. Collectively, it was evident that lead high dose (200 mg) dose and the male offspring were highly contaminated than their fathers. The present investigation recommended that urban population ad persons whose work is associated with exposure to lead. Would expected to be at increased risk for lead exposure that will extend to their offspring, and they should be submitted with antioxidants and subjected to periodical medical examinations

    2014-01-01

    Emerging research has demonstrated that the sex hormone estradiol regulates fear extinction in female rodents and women. Estradiol may also regulate fear extinction in males, given its role in synaptic plasticity in both sexes. Here we report that inhibition of estradiol synthesis during extinction training, via the aromatase inhibitor fadrozole, significantly impairs extinction recall in male rats. This deficit in extinction recall is not due to state-dependent memory formation and is comple...

    Males outperform females on some spatial tasks, and this may be partially due to the effects of sex steroids on spatial strategy preferences. Previous work with rodents indicates that low estradiol levels bias females toward a striatum-dependent response strategy, whereas high estradiol levels bias them toward a hippocampus-dependent place strategy. We tested whether testosterone influenced the strategy preferences in male rats. All subjects were castrated and assigned to one of three daily i...

    Full Text Available The aim of the present study was to evaluate the effect of melatonin as an antioxidant on spatial navigation memory in male diabetic rats. Thirty-two male white Wistar rats weighing 200 ± 20 g were divided into four groups, randomly: control, melatonin, diabetic and melatonin-treated diabetic. Experimental diabetes was induced by intraperitoneal injection of 50 mg kg-1 streptozotocin. Melatonin was injected (10 mg kg-1 day-1, ip for 2 weeks after 21 days of diabetes induction. At the end of administration period, the spatial navigation memory of rats was evaluated by cross-arm maze. In this study lipid peroxidation levels, glutathione-peroxidase and catalase activities were measured in hippocampus. Diabetes caused to significant decrease in alternation percent in the cross-arm maze, as a spatial memory index, compared to the control group (p < 0.05, whereas administration of melatonin prevented the spatial memory deficit in diabetic rats. Also melatonin injection significantly increased the spatial memory in intact animals compared to the control group (p < 0.05. Assessment of hippocampus homogenates indicated an increase in lipid peroxidation levels and a decrease in GSH-Px and CAT activities in the diabetic group compared to the control animals, while melatonin administration ameliorated these indices in diabetic rats. In conclusion, diabetes induction leads to debilitation of spatial navigation memory in rats, and the melatonin treatment improves the memory presumably through the reduction of oxidative stress in hippocampus of diabetic rats.

    Full Text Available Benzothiazoline HNC6H4SC︹(C6H5CH:C(OHCOOCH3 1 prepared by the condensation reaction of aroyl pyruvate and 2-aminothiophenol has been treated with Ph3Sb(OPri2 to yield Ph3Sb[SC6H4NC(C6H5CH:CO︹COOCH3] 2. These compounds have been characterized by elemental analyses and molecular weight determinations. The probable structures of the ligand as well as antimony complex have been tentatively proposed on the basis of IR and NMR (H1 and C13 spectral evidences. Both compounds have been tested for their antifertility activity in male albino rats. The oral administration of compounds 1 and 2 at the dose level of 10 mg/rat/day significantly reduced the weights of testes, epididymides, ventral prostate, and seminal vesicles. The production of preleptotene spermatocytes was decreased by 36.57%; 57.23%, pachytene spermatocytes by 40.06%; 62.01%, and secondary spermatocytes by 52.45%; 63.22%, following the treatment of compounds 1 and 2, respectively. The marked reduction in sperm motility and density resulted in infertility by 100%. Significant (P<.01 alterations were found in biochemical parameters of reproductive organs in treated animals as compared to control group. It is concluded that all these effects may finally impair the fertility of male rats.

    International Nuclear Information System (INIS)

    The present study aims to investigate the biological effects of carrot oil as an antioxidant, our results recorded that blood glutathione content (GSH), superoxide dismutase activity, catalase activity, total white blood cells count (WBCs), red blood cells (RBCs), hemoglobin content (Hb), haematocrit value (Hct%), platelets count (PLT) and serum testosterone were significantly decreased on the 1st and 7th day post-exposure to 7 Gy gamma irradiation, while serum total cholesterol level, triglycerides level and malondialdehyde (MDA) revealed a significant increase on the 1st and 7th days post-irradiation. Oral administration of carrot oil (200 mg/Kg b.w.) for consecutive 3 weeks before exposure to 7 Gy gamma irradiation in male albino rats, the data revealed significant amelioration in the previous parameters, it could be concluded that carrot oil capable of reducing the biological hazards induced by gamma irradiation

  13. The Possible Protective Role of Foeniculum vulgare Mill. Against Radiation-Induced Certain Biochemical Changes in Albino Rats

    International Nuclear Information System (INIS)

    This study was conducted to evaluate the modulating efficacy of prolonged oral administration of Foeniculum vulgare Mill. essential oil (FEO) against gamma irradiation-induced biochemical changes in male rats. Essential oil of Foeniculum vulgare Mill. was orally administrated at dose level of 250 mg/kg body wt/day for 21 days before irradiation and 7 days post exposure (6.5 Gy single dose). Rats exposed to ionizing radiation exhibited a potential elevation of serum aspartate aminotransferase (AST) and alkaline phosphatase (ALP) activities, bilirubin, urea and creatinine levels, lipid abnormalities, and an increase in tissue lipid peroxidation (LPO) and metallothioneins (MTs). On the other hand, noticeable drop in liver and kidney glutathione content and serum total protein, albumin and testosterone levels were recorded. Tissue organs displayed some changes in trace element concentrations, which may be due to the radiation ability to induce oxidative stress. The data obtained from rats treated with fennel oil before and after whole body gamma irradiation revealed significant modulation in the biochemical tested parameters and profound improvement in the activity of antioxidant status, glutathione and metallothioneins. The treatment of irradiated rats with fennel oil also appeared to be effective in minimizing the radiation-induced increase in lipid peroxidation as well as changes in essential trace elements in some tissue organs. In addition to its containing many chemical antioxidant constituents such as polyphenols, fennel was found to contain detectable concentrations of essential trace elements (Zn, Cu, Fe, Se, Mg, Mn and Ca) which may be involved in multiple biological processes as constituents of enzymes system including superoxide dismutase (Cu, Zn, Mn, SODs), oxide reductase, glutathione (GSP, GSH, GST), metallothionein MTs, etc. Overall, it could be concluded that Foeniculum vulgare Mill. essential oil exerts beneficial protective role against radiation-induced deleterious biochemical effects related to many organ functions and deteriorated antioxidant defense system.

    The present study was conducted on male albino rats of 120-150 gm. The effects of organophosphorus pesticides parathion methyl, azinphos methyl and pirimiphos methyl on liver and kidney functions and testosterone hormone were studied on three groups of rats, each group treated with one pesticide with daily oral administrations of 2.5 mg/kg, 2.0 mg/kg and 20.5 mg/kg respectively and fourth group served as control. Blood was collected after 7, 14, 21 and 28 days and two and four weeks recovery periods. The data obtained revealed significant decrease in serum albumin, albumin to globulin ratio (A/G) and high density lipoprotein (HDL) while significant increases in serum creatinine, urea and globulin in all groups of treated rats were recorded. The increases remained higher than the controls even after the recovery periods, which lead to kidney dysfunction. Testosterone level was significantly decreased with no recovery tendency

    Full Text Available Ten Fisher rats 50 to 55 days of age made up the pubertal group, and ten rats 90 to 95 days of age served as the controls. The testicular and epididymal weights and volumes of the pubertal males were lower than those of the controls (P0.05. At the beginning of gestation, the pubertal dams weighed less than the controls (P<0.001 but following uterectomy the body weights were equal. Pubertal dams delivered fewer pups than the controls (8.1 ± 2.5 vs 10.4 ± 1.3, P<0.05. There was no difference in the body weights of their offspring or in the weights of their placentas. The results suggest that, in contrast to their female counterparts, pubertal male rats are not fully mature and have not reached complete reproductive capacity at 50-55 days of age.

Male rats were divided into three groups. First group served as control, second group administrated s.c. cadmium chloride (2.5 mg kg -1 and third group injected s.c. with Sel (0.35 mg kg -1 and Cd. In the last group, the animals were treated with Sel one hour before Cd treatment. Blood samples were collected and eight animals were sacrificed after two, four, six and eight weeks. Plasma testosterone, FSH and LH were assayed using enzyme immunoassay method. The sperm quality was evaluated. Cd in the testes was determined using atomic absorption. The weights of body, testes and accessory sex organs were recorded. The treatment of the rats with Cd results in a significant decrease of testosterone, LH, sperm motility (%, body gain and weights of testes, epididymis, vas deference, seminal vesicle and prostate gland. On the other hand, the sperm abnormalities and FSH concentration increased significantly in Cd treated rats. Cd content in the testes of second group and third group increased in a time-related fashion. Cd concentration in the testes of rats treated with Cd and Sel was less than that of rats injected with Cd alone. Sel was found to reduce the deleterious effects of Cd.

Stress caused by forced swimming was demonstrated by a significant increase in the latency of the pain response in the hot-plate test (14.6 ± 1.25 s for control males vs 26.0 ± 1.53 s for stressed males, P = 0.0004). No changes were observed in body weight, testicular weight, seminal vesicle weight, ventral prostate weight or gross histological features of the testes of stressed males. Similarly, no changes were observed in fertility rate, measured by counting live fetuses in the uterus of normal females mated with control and stressed males; no dead or incompletely developed fetuses were observed in the uterus of either group. In contrast, there was a statistically significant decrease in spermatid production demonstrated by histometric evaluation (154.96 ± 5.41 vs 127.02 ± 3.95 spermatids per tubular section for control and stressed rats, respectively, P = 0.001). These data demonstrate that 15 days of forced swimming stress applied to adult male rats did not impair fertility, but significantly decreased spermatid production. This suggests that the effect of stress on fertility should not be assessed before at least the time required for one cycle of spermatogenesis.

    Apelin is a novel bioactive peptide as the endogenous ligand for APJ. Apelin and APJ have also been identified in the testis, hypothalamic nuclei such as arcuate, supraoptic and paraventricular nuclei, implicating roles in the control of reproduction. Therefore, the present study was designed to investigate the effects of chronic central infusion of apelin-13 on LH, FSH and testosterone levels and testis morphology. 21 Wistar-Albino male rats received continuous intracerebroventricular infusion via Alzet osmotic mini pumps filled artificial cerebrospinal fluid (vehicle) or apelin-13 at concentrations of 1 or 10 nmol (10 ?l/h) for seven days. At the last 90 min of the infusion period, the blood samples were collected at 15 min intervals (0-90 min) for LH and FSH analyses. At the last sampling point, the blood samples were analyzed for testosterone levels. Infusion of high dose apelin-13 significantly suppressed LH release compared with the vehicle values at 30, 60 and 75 min (papelin-13 group were statistically lower than the control group (papelin-13 significantly decreased the number of Leydig cells compared with the control and lower dose apelin-13 groups (papelin-13 may play a role in the central regulation and decreases testosterone release by suppressing LH secretion. Thus, antagonists of the apelin receptor may, therefore, be useful for pharmaceuticals in the treatment of infertility. PMID:26149233

    A number of herbal drugs are advocated in the traditional Ayurvedic literature for the improvement of overall sexual function. Young roots of Bombax ceiba Linn. (Fam. Bombacaceae) [correction added after online publication 1 August 2011: the family of Bombax ceiba was incorrectly mentioned as Orchidaceae. It has been corrected to Bombacaceae] also known as Semal Musli are used traditionally in Indian subcontinent as sexual stimulant. Its juice is considered nutritive and restorative tonic. Lyophilised aqueous extract of roots was studied for effect on sexual behaviour and spermatogenesis in male albino rats. Administration of 100 mg Kg(-1) body weight of aqueous extract influenced the five parameters evaluated in vivo. Sexual behaviour analysis in the presence of a female rate, serum testosterone level, anabolic effects, epididymal sperm count and seminal fructose level were the parameters evaluated. In B. ceiba extract-treated animals, a gain in body and sexual organ weights was observed. Mount, intromission and ejaculation frequencies were significantly improved (P 0.05). Seminal fructose content and epididymal sperm count were significantly improved as well. Penile erection index was also higher compared to control group animals. Hesitation time was significantly reduced (P < 0.01), and copulatory rate was doubled in treated animals compared with control group animals. PMID:21806665

    Full Text Available Problem statement: Aluminum (Al is an indifferent element from a toxicological point of view. In recent years, however, Al has been implicated in the pathogenesis of several clinical disorders. One of the most frequently described problem in aluminum toxicity is anemia. The present study was carried out to determine the effectiveness of Camel?s milk in alleviating the toxicity of aluminum chloride (AlCl3 on certain hematological parameters, lipid peroxidation and oxidative stress enzyme in the RBC?s of white albino rats. Approach: Ten rats per group were divided into three treatment groups: Group one were rats given normal saline and served as control group, group two were rats treated with 1 ml of AlCl3 (0.5 mg kg-1 body weight and named AlCl3 treated rats, group 3 were rat treated with 1ml fresh camel?s milk 10 min before the administration of AlCl3 (0.5 mg kg-1 body weight and named Camel?s milk and AlCl3 treated rats. Rats were orally administered their respective doses every day for 30 days. Evaluations were made for hematological parameters in the blood and for lipid peroxidation and oxidative stress enzymes activities in the RBC?s. Results: Results obtained showed that oral AlCl3 treatment caused a significant decrease (p3 induced free radicals and as a result caused an increase the concentration of Thiobarbituric Acid Reactive Substances (TBARS and decreased activities of Superoxide Dismutase (SOD and Catalsae (CAT in the RBCs homolysate. The oral administration of Camel?s milk before the administration of AlCl3, alleviated it?s toxic effect. Camel?s milk administration resulted in a significant increase (p3 treated rats. Camel?s milk reduced free radicals production and oxidative stress status in the RBC?s noticed by the significant decreased levels of TBARS and increased activities of SOD and CAT when compared to AlCl3 treated rats. Conclusion: our data proved that there is an alternation in the hematological parameters and antioxidant system in the red blood cells of rats administered aluminum chloride orally, whereas oral administration of Camel?s milk prior the administration of Aluminum chloride protects the red blood cell form toxic effect of aluminum.

  9. Biochemical study on the effect of some antioxidants on apoptosis in irradiated male rats

    International Nuclear Information System (INIS)

    Male albino rats were whole body subjected to 2 Gy every other day up to a total dose of 8 Gy. Animals sacrificed on the 8th day after irradiation showed significant decreases in testis/body weight ratio. Biochemical analysis in testicular tissues showed significant decreases in SOD and CAT activities, concomitant with significant increase in XO activity and TBARS contents. Radiation exposure induced also significant increases in testicular DNA fragmentation, significant increases in mitochondrial NO and Ca+2 contents associated with significant decrease in nuclear GSH content. Testicular LDL-C content showed a significant increase which was much higher than its increase in serum, the content of HDL-C increased significantly, contrarily to serum where a significant decrease was recorded. Histological examination through electron microscope revealed apoptosis in testicular tissue. Either allopurinol (50 mg/kg body weight supplied via intra peritoneal injection) or Hesperidine (200 mg/kg body weight supplied orally by gastric intubation) or allopurinol + hesperidine supplied to rats during 7 consecutive days before irradiation or during 7 consecutive days after irradiation resulted in significant decrease of apoptosis associated with significant amelioration in the disequilibrium between antioxidants and oxidants. All treatments have improved the biochemical alteration in testicular tissues as well as mitochondrial and nuclear changes. However, the improvement was significantly higher when allopurinol, or hesperidine or allopurinol + hesperidine were administered pre-irradiation than post-irradiation. According to the results obtained in the current study, it could be concluded that antioxidants supplementation would protect testicular tissues from apoptosis.

    The effect of dried fruit extract from Xylopia aethiopica (Annonaceae) (XA) and vitamin C (VC) against ?-radiation-induced liver and kidney damage was studied in male Wistar rats. XA and VC were given orally at a dose of 250 mg/kg, orally for 6 weeks prior to and 8 weeks after radiation (5 Gy). The rats were sacrificed after 1 and 8 weeks of single exposure to radiation. Results showed that all animals in un-irradiated group survived (100%), while 83.3% and 66.7% survived in XA- and VC-treated groups, respectively, and 50% survived in irradiated group. The levels of serum, liver and kidney lipid peroxidation (LPO) were elevated by 88%, 102% and 73% after 1 week of exposure, and by 152%, 221% and 178%, after 8 weeks of exposure, respectively. Treatment with XA and VC significantly (p<0.05) decreased the levels of LPO in the irradiated animals. Also, ?-radiation caused significant decreases (p<0.05) in the levels of liver glutathione (GSH), glutathione-S-transferase (GST), catalase (CAT), superoxide dismutase (SOD), kidney GSH and SOD by 41%, 60%, 81%, 79%, 72% and 58% after 1 week of exposure. Similarly, ?-radiation caused significant increases (p<0.05) in the levels of serum alanine (ALT) and aspartate aminotransferases (AST) after 8 weeks of exposure. Precisely, ALT and AST levels were increased by 69% and 82%, respectively. These changes were significantly (p<0.05) attenuated in irradiated animals treated with XA and VC. These results suggest that XA and VC could increase the antioxidant defence systems in the liver and kidney of irradiated animals, and may protect from adverse effects of whole body radiation.

  11. Bone metabolism of male rats chronically exposed to cadmium

    International Nuclear Information System (INIS)

    Recently, based on a female rat model of human exposure, we have reported that low-level chronic exposure to cadmium (Cd) has an injurious effect on the skeleton. The purpose of the current study was to investigate whether the exposure may also affect bone metabolism in a male rat model and to estimate the gender-related differences in the bone effect of Cd. Young male Wistar rats received drinking water containing 0, 1, 5, or 50 mg Cd/l for 12 months. The bone effect of Cd was evaluated using bone densitometry and biochemical markers of bone turnover. Renal handling of calcium (Ca) and phosphate, and serum concentrations of vitamin D metabolites, calcitonin, and parathormone were estimated as well. At treatment with 1 mg Cd/l, corresponding to the low environmental exposure in non-Cd-polluted areas, the bone mineral content (BMC) and density (BMD) at the femur and lumbar spine (L1-L5) and the total skeleton BMD did not differ compared to control. However, from the 6th month of the exposure, the Z score BMD indicated osteopenia in some animals and after 12 months the bone resorption very clearly tended to an increase. The rats' exposure corresponding to human moderate (5 mg Cd/l) and especially relatively high (50 mg Cd/l) exposure dose- and duration-dependently disturbed the processes of bone turnover and bone mass accumulation leading to formation of less dense than normal bone tissue. The effects were accompanied by changes in the serum concentration of calciotropic hormones and disorders in Ca and phosphate metabolism. It can be concluded that low environmental exposure to Cd may be only a subtle risk factor for skeletal demineralization in men. The results together with our previous findings based on an analogous model using female rats give clear evidence that males are less vulnerable to the bone effects of Cd compared to females

    Background and Objectives Amiodarone (AM), a class 3 antiarrhythmic drug, has been associated with variety of adverse effects, the most serious of which is pulmonary toxicity. Ator (A) is a statin, known for their immunomodulatory and anti-inflammatory activities. Recent studies provide evidence of potential therapeutic effect of statins on lung injury. Adipose derived stem cells (ADSCs) have shown great promise in the repair of various tissues. The present study aimed at investigating and comparing the possible therapeutic effect of A and ADSCs on AM induced lung injury in albino rats. Methods and Results 34 adult male albino rats were divided into 5 groups: control group (Gp I), A group (Gp II) received 10 mg/kg of A orally 6 days (d)/week (w) for 4 weeks (ws), AM group (Gp III) received 30 mg/kg of AM orally 6 d/w for 4 ws, AM&A group (Gp IV) received AM for 4ws then A for other 4 ws and AM&SCs group (Gp V) received AM for 4 ws then injected with 0.5 ml ADSCs on 2 successive days intravenously (IV). Histological, histochemical, immunohistochemical and morphometric studies were performed. Group III displayed bronchiolitis obliterans, thickened interalveolar septa (IAS) and thickened vascular wall which were proven morphometrically. Increased area% of collagen fibers and apoptotic changes were recorded. All findings regressed on A administration and ADSCs therapy. Conclusion Ator proved a definite ameliorating effect on the degenerative, inflammatory, apoptotic and fibrotic changes induced by AM. ADSCs administration denoted more remarkable therapeutic effect compared to A. PMID:26634065

    Full Text Available Effects of estrogen in the brain regions which are not directly related to neuroendocrine functions are not fully known. Therefore we investigated the long term effects on the cerebellar cortex of a neonatally (3rd day administered single dose (1 mg of estrogen. Golgi impregnated and paraffin sections (Bielschowsky, Klûver-Barerra and basic fuchsin-alcian-blue of cerebella of 10 treated adult (365 days old male rats and of 10 matched controls were studied. Simultaneous to the morphological analysis of the cerebellar cortex, stereological methods were applied. In treated rats the Purkinje neurons had a more developed dendritic arborisation with numerous spines, but had significantly decreased (p<0.001 cellular body volumes (14 x 10-3 mm3 in comparison to controls (27 x 10-3 mm3. In treated animals the molecular layer thickness (148.94 ?m of the cerebellar cortex was significantly decreased (p<0.001 compared to controls (514.52 ?m, and the thickness of the granular layer (372.35 ?m was significantly (p<0.001 increased compared to controls (270.80 ?m. In treated rats the number of neurons in the granular layer was 338.87 mm2 (controls 118.81 mm2 and in the molecular layer was 22.86 mm2 (controls 55.23 mm2. Our results indicate significant and long term effects of a single dose of estrogen (administered in the neonatal period on the cerebellar cortex of male rats.

  18. Disposition of perfluorodecanoic acid in male and female rats

    International Nuclear Information System (INIS)

    The elimination, tissue distribution, and metabolism of [1-14C]PFDA were examined in male and female rats for 28 days after a single ip dose (9.4 mumol/kg, 5 mg/kg). A sex difference in the fecal elimination of perfluorodecanoic acid (PFDA) was observed with 51 and 24% of the administered 14C being recovered in the feces of male and female rats, respectively, by 28 days post-treatment. The cumulative excretion of PFDA-derived 14C in the urine in 28 days was less than 5% of the administered dose in both sexes. The sex-related difference in the rate of fecal elimination resulted in the observed difference in whole body elimination t1/2 of PFDA in males (t1/2 = 23 days) and females (t1/2 = 45 days). The liver contained the highest concentration of PFDA-derived 14C in both males and females, followed by the plasma and kidneys. The heart, fat pads, testes, and gastrocnemius muscle of males, and the ovaries of females contained much lower concentrations of PFDA. The reason for the high percentage of the ip dose of [1-14C]PFDA in the liver (53% males and 41% females, 2 hr post-treatment) was further examined using an in situ nonrecirculating liver perfusion technique. It was shown that approximately 25% of the [14C]PFDA in the perfusate was extracted by the liver in a single pass. The basis for the sex difference in fecal elimination of PFDA does not appear to be due to a sex difference in biliary excretion. In a 6-hr period, male and female rats with kidneys ligated eliminated essentially the same percentage dose of [14C]PFDA into bile. We had hypothesized that the persistence of PFDA in rats was due to formation of a PFDA-containing lipids. However, no evidence that PFDA is conjugated to form persistent hybrid lipids was obtained, nor were polar metabolites of PFDA detected in urine or bile

Materials and Methods: This experiment was performed on 30 Wistar-Albino male rats, weighing 200-250 g, which were divided in sham control (A, diabetic control (B and diabetic test groups (C randomly (N=10. Type I diabetes was induced by single intraperitoneal injection of STZ (65 mg/kg. Test group received 0.40-0.60 ml of Urtica dioica decoction for a month by gavages, control group (B received the same volume of distill water. Group (A did not receive any agent during the experiment period. Finally, animals were anesthetized, sacrificed and blood samples were collected from the cervical vein. Then, serum glucose and lipid profiles were measured by ordinary methods. Data were analyzed by SPSS-11, using ANOVA and post hoc Tukey tests. Results were expressed as mean±SD, and statistical difference was considered significant by p<0.05.Results: Results in the present study showed that fasting blood glucose (FBS, total cholesterol (TCho, triglyceride (TG, LDL, food and water intake were significantly decreased in group C compared with those of group B, but body weight gain was significantly increased compared with that of control group (B.Conclusion: These results indicated that Urtica dioica decoction caused decreased FBS and improved serum lipids in diabetic male rats. Some more studies have shown the same mechanism.

    Full Text Available Purpose: Parkinson’s disease (PD is a progressive neurodegenerative disease. Recent studies have indicated a higher prevalence of PD in male gender. Furthermore testosterone deficiency is more common among male parkinsonians in compare to healthy men. This study was aimed to investigate the effect of testosterone on catalepsy, in male rats. Methods: The study carried out on male Wistar rats. To induce catalepsy, haloperidol (1 mg/kg, i.p as D2 antagonist was administered before testing animals via Bar test. Animals were gonadectomized to investigate testosterone elimination effect on catalepsy, and also the androgen receptor blocker, flutamide, and the aromatase inhibitor, letrozole, were administered in certain groups of animals. The bar test method was used to evaluate haloperidol-induced catalepsy. Results: Haloperidol 1 mg/kg, i.p, was able to induce catalepsy. Gonadectomy worsened the catalepsy and subchronic testosterone replacement could restore this effect to the level of normal animals. While low dose of flutamide administration represented an improvement in cataleptic symptoms, higher doses worsened catalepsy. Letrozole(4mg/kg,sc administered animals represented nearly the same cataleptic symptoms as the control group. Conclusion: Testosterone deficiency increases catalepsy and testosterone replacement can significantly be effective in catalepsy remission. It seems that the anticataleptic effect of testosterone is exerted through affecting on androgenic receptors.

    Full Text Available Objective. This study aimed to investigate the sensitivity of the testis, epididymis, seminal vesicle, and sperm acrosome reaction (AR to monosodium L- glutamate (MSG in rats. Materials and methods. Rats were divided into four groups and fed with non-acidic MSG at 0.25, 3 or 6 g/kg body weight for 30 days or without MSG. The morphological changes in the reproductive organs were studied. The plasma testosterone level, epididymal sperm concentration, and sperm AR status were assayed. Results. Compared to the control, no significant changes were discerned in the morphology and weight of the testes, or the histological structures of epididymis, vas deferens and seminal vesicle. In contrast, significant decreases were detected in the weight of the epididymis, testosterone levels, and sperm concentration of rats treated with 6 g/kg body weight of MSG. The weight loss was evident in the seminal vesicle in MSG-administered rats. Moreover, rats treated with MSG 3 and 6 g/kg exhibited partial testicular damage, characterized by sloughing of spermatogenic cells into the seminiferous tubular lumen, and their plasma testosterone levels were significantly decreased. In the 6 g/kg MSG group, the sperm concentration was significantly decreased compared with the control or two lower dose MSG groups. In AR assays, there was no statistically significant difference between MSG-rats and normal rats. Conclusion. Testicular morphological changes, testosterone level, and sperm concentration were sensitive to high doses of MSG while the rate of AR was not affected. Therefore, the consumption of high dose MSG must be avoided because it may cause partial infertility in male.

    Full Text Available Background Lemon verbena (Lippia citriodora has been known to have various pharmacologic activities. Objectives Lemon verbena leaves are used to make an herbal tea, which is traditionally used for treating spasms, common cold, severe abdominal pain, indigestion, insomnia, anxiety, and headache. Although it has been known to have various pharmacologic activities, no scientific study has been done to assess its effects yet. In this study aimed to assess the effect of the aqueous extract of lemon verbena on memory of male rats by using the passive avoidance task. Materials and Methods In this study, Wistar male rats (weight, 180-250 g were recruited. Aqueous extract of lemon verbena leaves was prepared. A total of 40 Wistar male rats were randomly allocated to five groups (n = 8. Saline for control group and aqueous extract of lemon verbena in four experimental groups were administered intraperitoneally (respectively 10, 100, 500, and 1000 mg/kg for seven days. Then passive avoidance learning test was used to evaluate learning and memory. On the seventh day, acquisition test was performed an hour after treatment and the retention test was performed on the next day. Results Analysis of data showed that in comparison to controls, treatment with the aqueous extract of lemon verbena (? 100 mg/kg had decreased the step-through latency (STL (P < 0.001. Moreover, treatment of the rats with the extract doses of ? 500 mg/kg had increased the total time spent in the dark compartment (TDC in comparison to controls (P < 0.001. Conclusions These results indicated that aqueous extract of lemon verbena (? 100 mg/kg has undesirable effects on memory; however, understanding the underling mechanisms needs further investigation.

    The purpose of this study was to investigate the effects of zinc oxide nanoparticles (nZnO) on adult male Wistar rats. Thirty male Wistar rats divided into five groups of six animals each were used for this study. For ten days, Groups one to four continuously received 50, 100, 150 and 200 mg/kg nZnO, respectively. Group five served as the control group. At the end of the study, the rats were sacrificed and histopathological study of the liver and renal tissue, sperm analysis, serum oxidative stress parameters and some liver enzymes were done. The results of this study showed that nZnO at concentration more than 50 mg/kg lead to significant changes in liver enzymes, oxidative stress, liver and renal tissue and sperm quality and quantity. In conclusion, the toxicity of nZnO is more significant when the concentration is increased; however, the use of low doses requires further investigation. PMID:26316185

    Full Text Available The effect of iron fortified ‘gari’, a cassava fermented meal on serum iron, hemoglobin concentration and total iron binding capacity on Albino Wistar rats were investigated. The prevalence of Iron Deficiency Anemia (IDA among the low income house-hold is high in developing countries due to low intake of dietary iron. Developing an intervention strategy for IDA is a major concern and food fortification is considered the sustainable strategy to alleviate IDA. Freshly grated cassava tubers were divided into four subsamples; A-C and then mixed with Ferrous Sulphate (FS, Iron (III sulphate (F3 and Ferric Alum (FA, respectively in ratio 1:5000 (0.2 g fortificant kg-1 mash. The samples along with the Control (D were each fermented in a solid state for 24 h and stir-fried to obtain gari granules. The gari samples were fed to rats divided into four groups of five for fourteen days and the serum, then analyzed for serum iron concentration, Total Iron Binding Capacity (TIBC and hemoglobin concentration. The results showed significant increase (p-1 and hemoglobin (13.63±2.8 g dL-1 and significantly lower level (55.5±2.2 ?mol L-1 of TIBC(p<0.05, indicating a better iron bioavailabilty. The findings suggests that fortification of gari with Ferrous Sulphate (FS had higher bioavailability of iron and therefore hold promise in combating iron deficiency anemia.

    We showed previously that the number of spike-wave discharges (SWDs) was increased after intraperitoneal (i.p.) injection of lipopolysaccharide (LPS), inosine (Ino) and muscimol alone whereas i.p. guanosine (Guo), uridine (Urd), bicuculline, theophylline and (+)-5-methyl-10,11-dihydro-5H-dibenzo(a,d)cyclohepten-5,10-imine maleate (MK-801) alone decreased the SWD number in Wistar Albino Glaxo/Rijswijk (WAG/Rij) rats. These drugs may exert their effects on absence epileptic activity mainly via proinflammatory cytokines-evoked increase in cortical excitability (such as LPS), GABAergic system (LPS, Ino, Urd, muscimol and bicuculline), glutamatergic system (LPS, Guo and MK-801) and adenosinergic system (LPS, Ino, Guo, Urd and theophylline). Both GABAergic system and glutamatergic system are involved in the pathomechanism of absence epilepsy, the LPS-evoked increase in absence epileptic activity and the pro- or antiepileptic effects of non-adenosine (non-Ado) nucleosides Ino, Guo and Urd. Moreover, Ino, Guo and Urd have modulatory effects on inflammatory processes. Thus, we investigated whether Ino, Guo and Urd have also modulatory influence on LPS-evoked increase in SWD number using two different concentrations of each nucleoside in WAG/Rij rats. We demonstrated that Ino dose-dependently aggravated whereas Guo and Urd attenuated the LPS-evoked increase in SWD number. Our results suggest that different nucleosides have diverse effects on LPS-induced changes in absence epileptic activity. PMID:26365718

  9. Ameliorative Role of Marjoram Against Ionizing Radiation-Induced Biochemical and Histological Changes in Thyroid Gland in Male Rats

    International Nuclear Information System (INIS)

    The present study was designed to determine the possible protective effects of marjoram, grey green leaf, against gamma radiation-induced oxidative damage in thyroid gland of male albino rats. Marjoram (100 mg/kg/day) was given to rats via gavages for 30 consecutive days prior exposure to irradiation (4.5 Gy) and the last dose of marjoram was administered 24 hr before irradiation. Thyroid gland was taken for histological study and blood samples for biochemical analysis on the 7th and 15 th day post-irradiation. In the irradiated group, the histological observations of thyroid gland sections showed distortion of the thyroid follicles together with apparent swelling of the follicular cells, vacuolated cytoplasm and ill-defined cell boundaries of the follicular epithelium. Biochemical analysis in the blood showed significant decrease in serum tri-iodothyronine (T3) and thyroxine (T4). Also, a significant decrease was observed in serum superoxide dismutase (SOD) and catalase (CAT), and blood glutathione (GSH). Treatment with marjoram (100 mg/kg) was found to offer significant protection against gamma radiation induced toxicity in thyroid gland tissues which was evident by improved status of most parameters under investigation. These results suggest that marjoram could increase the antioxidant defence systems of thyroid gland and may protect from adverse effects of whole body gamma radiation.

    Full Text Available Introduction: The principal dose-limiting factor in the use of cisplatin as an antineoplastic drug is its hepatic toxicity. This study was designed to investigate the protective role of taurine against cisplatin-induced hepatic injury. Methods: Male albino rats (180-220 g were divided in to 4 groups (n=8 as follows: (1 saline-treated group (2: cisplatin-treated group (10 mg/kg ip (3: group that received taurine (200 mg/kg ip for 1hr before cisplatin (10 mg/kg ip administration (4: taurine treated group (200 mg/kg ip. After 7 days, the animals were sacrificed and blood samples collected from the heart as well as liver tissues were kept at -70 °C till further analyses. Results: analyses showed that cisplatin significantly increased ALT and AST serum levels (P<0.05 while pretreatment with taurine resulted in the reduction of these markers. Catalase activity in cisplatin-treated rats was significantly decreased (P<0.05 and taurine administration could recover this reduction. MDA content of the liver tissue was significantly increased in cisplatin-exposed animals, while taurine treatment reduced the amount of MDA in liver tissue. Conclusion: Our data suggest that taurine prevents from cisplatin-induced hepatic injury and this effect may be due to its antioxidant properties.

  11. Efficacy of wheat germ oil in alleviating certain disorders induced by aspirin administration and/or ?-irradiation in pregnant albino rats and their foetuses

    International Nuclear Information System (INIS)

    Aspirin is one of the most commonly used nonsteroidal anti-inflammatory drugs, induces during pregnancy high incidence of developmental anomalies in pregnant rats when given on specific days during stage of organogenesis. Accordingly, this study was performed to clarify the beneficial effect of maternal intake of wheat germ oil on the effect of aspirin administration and/or radiation induced maternal and foetal detrimental impact. Pregnant albino rats were administered aspirin from the gestational day (GD), 6 to (GD) 17 at a dose of 250 mg kg/day body wt and exposed to whole body ?-irradiation at dose of 0.5 Gy for 4 times on GD 9,10,11 and 12 days from pregnancy. The extent of lipid peroxidase formation as well as estimation of alkaline phosphatase and total proteins content in tissues of liver and placenta was used as sensitive parameters of choice to evaluate tissue damage. Radiation exposure and aspirin administration induced marked elevation in lipid peroxidase (malondialdehyde), alkaline phosphatase, accompanied by decline in total protein content in placenta and liver tissues. In addition, miscellaneous malformations including anopthalmia, microtia, excencephaly, diminution of size or kypophysis were designated. The results showed that supplementation of pregnant female rats with wheat germ oil were able to reduce the high levels of malondialdehyde, alkaline phosphatase. Total protein content returned once more to its normal pattern. Also, reduction of severe deleterious symptoms of radiation and aspirin administration inducing i foetal mortality were reduced. Wheat germ oil showed to increase growth in surviving foetuses and remarkable protection against severe morphological deformities as well as biochemical, histochemical and embryological disorders

  13. Teratogenicity Induced By 13-Cis-Retinoic Acid and/or Gamma Irradiation on Bone of Fetuses and Placenta of Pregnant Albino Rats

    International Nuclear Information System (INIS)

    Isotretinoin (13-cis retinoic acid) has revolutionized the management of severe treatment-resistant acne and it has been widely used for a range of dermatological conditions. During pregnancy, high incidence of developmental anomalies were occurred in pregnant rats given isotretinion and/or exposed to gamma irradiation on specific days during organogenesis. The objective of this study was to evaluate the side effects of isotretinoin administration and/or exposure to gamma radiation on the placenta of pregnant rats, vertebrae and neural spine of their fetuses. Isotretinoin at the dose level 70 mg/kg was daily administered via an oral stomach tube to pregnant adult albino rats from the 11th to 15th days of pregnancy while mothers were subjected to gamma radiation 1.5 Gy as fractionated dose (0.5 Gy/3 times) on the 11th, 12th and 13th day of gestation. The experimental investigations carried out one day prior to parturition (the 20 th day of gestation) have demonstrated that isotretinoin intake from the 11th-15th days of gestation induced embryological, biochemical, histochemical and histopathological disorders in irradiated mothers and their fetuses. The data obtained revealed that isotretinoin administration and/or gamma irradiation caused significant elevation in alkaline phosphatase accompanied by a decline in total protein and DNA in the placenta tissues and vertebrae bone. In addition, histopathological results showed different distortions in the placenta which varied from necrotic nuclei of giant cells, haemorrhage and pyknotic nuclei in trophoblast. Moreover, ill-shaped vertebrae with degenerated osteogenic layers and reduced number of chondrocytes together with severe damage in spine neural arch were viewed. In conclusion, isotretinoin is a serious and powerful drug and should be used with great caution, therefore, it is recommended that radiation workers especially females have to be careful toward isotretinoin intake during pregnancy.

    Full Text Available The present study investigated the effects and potential mechanism(s of action of icariin on the reproductive functions of male rats. Adult rats were treated orally with icariin at doses of 0 (control, 50, 100, or 200 mg/kg body weight for 35 consecutive days. The results show that icariin had virtually no effect on the body weight or organ coefficients of the testes or epididymides. However, 100 mg/kg icariin significantly increased epididymal sperm counts. In addition, 50 and 100 mg/kg icariin significantly increased testosterone levels. Real-time PCR suggests icariin may be involved in testosterone production via mRNA expression regulation of genes such as peripheral type benzodiazepine receptor (PBR and steroidogenic acute regulatory protein (StAR. Furthermore, 100 mg/kg icariin treatment also affected follicle stimulating hormone receptor (FSHR and claudin-11 mRNA expression in Sertoli cells. Superoxide dismutase (SOD activity and malondialdehyde (MDA levels were measured in the testes; 50 and 100 mg/kg icariin treatment improved antioxidative capacity, while 200 mg/kg icariin treatment upregulated oxidative stress. These results collectively suggest that icariin within a certain dose range is beneficial to male reproductive functions; meanwhile, higher doses of icariin may damage reproductive functions by increasing oxidative stress in the testes.

    Full Text Available Abstract Background Dobutamine stress echocardiography is used to investigate a wide variety of heart diseases in humans. Dobutamine stress echocardiography has also been used in animal models of heart disease despite the facts that the normal response of healthy rat hearts to this type of pharmacological stress testing is unknown. This study was performed to assess this normal response. Methods 15 normal adult male Wistar rats were evaluated. Increasing doses of dobutamine were infused intravenously under continuous imaging of the heart by a 12 MHz ultrasound probe. Results Dobutamine stress echocardiography reduced gradually LV diastolic and systolic dimensions. Ejection fraction increased by a mean of +24% vs. baseline. Heart rate increased progressively without reaching a plateau. Changes in LV dimensions and ejection fraction reached a plateau after a mean of 4 minutes at a constant infusion rate. Conclusion DSE can be easily performed in rats. The normal response is an increase in heart rate and ejection fraction and a decrease in LV dimensions. A plateau in echocardiographic measurements is obtained after 4 minutes of a constant infusion rate in most animals.

    Female rats show a distinct attraction for males. This attraction remains consistent without the necessity for the physical presence of the male. However, the identity of the olfactory cues contributing to attraction in rats remains unknown. Rat urine contains copious amounts of major urinary proteins (MUPs). Here, we investigated the hypothesis that MUPs mediate sexual attractiveness in rats. We first demonstrated that a member of a male dyad receiving greater copulatory opportunities in competitive mate choice tests excrete greater amounts of MUPs. Furthermore, the amount of male MUPs positively correlated with both copulatory opportunities received and female exploration of the urine. Using females and a two-choice olfactory attraction test, we demonstrated that urinary fractions containing MUPs were sufficient to induce attraction and that male MUPs activated neurons in the posterodorsal medial amygdala in female rats. Taken together, these results suggest that olfactory cues associated with MUPs act as an attractant to female rats in estrus. PMID:25359898

    Indium, a rare earth metal characterized by high plasticity, corrosion resistance, and a low melting point, is widely used in the electronics industry, but has been reported to be an environmental pollutant and a health hazard. We designed a study to investigate the effects of subacute exposure of indium compounds on male reproductive function. Twelve-week old male Sprague-Dawley rats were randomly divided into test and control groups, and received weekly intraperitoneal injections of indium acetate (1.5 mg/kg body weight) and normal saline, respectively, for 8 weeks. Serum indium levels, cauda epididymal sperm count, motility, morphology, chromatin DNA structure, mitochondrial membrane potential, oxidative stress, and testis DNA content were investigated. The indium acetate-treated group showed significant reproductive toxicity, as well as an increased percentage of sperm morphology abnormality, chromatin integrity damage, and superoxide anion generation. Furthermore, positive correlations among sperm morphology abnormalities, chromatin DNA damage, and superoxide anion generation were also noted. The results of this study demonstrated the toxic effect of subacute low-dose indium exposure during the period of sexual maturation on male reproductive function in adulthood, through an increase in oxidative stress and sperm chromatin DNA damage during spermiogenesis, in a rodent model. © 2014 Wiley Periodicals, Inc.

    In this study, N-methacryloyl-l-phenylalanine (MAPA) containing poly(2-hydroxyethylmethacrylate) (HEMA)-based magnetic poly(HEMA-MAPA) nanobeads [mag-poly(HEMA-MAPA)] were radiolabeled with (131) I [(131) I-mag-poly(HEMA-MAPA)], and the radiopharmaceutical potential of (131) I-mag-poly(HEMA-MAPA) was investigated. Quality control studies were carried out by radiochromatographic method to be sure that (131) I binded to mag-poly(HEMA-MAPA) efficiently. In this sense, binding yield of (131) I-mag-poly(HEMA-MAPA) was found to be about 95-100%. In addition to this, optimum radiodination conditions for (131) I-mag-poly(HEMA-MAPA) were determined by thin-layer radiochromatography studies. In addition to thin-layer radiochromatography studies, lipophilicity (partition coefficient) and stability studies for (131) I-mag-poly(HEMA-MAPA) were realized. It was determined that lipophilicities of mag-poly(HEMA-MAPA) and (131) I-mag-poly(HEMA-MAPA) were 0.12?±?0.01 and 1.79?±?0.76 according to ACD/logP algorithm program, respectively. Stability of the radiolabeled compound was investigated in time intervals given as 0, 30, 60, 180, and 1440?min. It was found that (131) I-mag-poly(HEMA-MAPA) existed as a stable complex in rat serum within 60?min. After that, biodistribution and scintigraphy studies were carried out by using albino Wistar rats. It was determined that the most important (131) I activity uptake was observed in the breast, the ovary, and the pancreas. Scintigraphy studies well supported biodistribution results. PMID:24339009

  6. Improvement of Lipid Profile and Antioxidant Status of Hyperlipidaemic Albino Rats by Gamma-irradiated Safflower (Carthamus tinctorius L.)

    International Nuclear Information System (INIS)

    Hyper-Lipidemia is a dominant risk factor that contributes to the development and progression of atherosclerosis. Safflower is rich in the essential omega-6 and omega-3 polyunsaturated fatty acids and phenolic compounds which are known to be effective for the treatment of hyper- lipidemia. This study was performed to examine the efficacy of safflower to ameliorate the induced hyper-lipidemia in rats. The results obtained revealed that rats fed on high fat diet (HFD) significantly induced an increase in lipid profile, glucose and some liver enzymes as well as elevation of malondialdehyde (MDA) associated with a significant decrease in high density lipoprotein (HDL-C), glutathione (GSH) content and some antioxidant enzymes activity. However, when rats received HFD containing either raw or irradiated safflower (1% w/w), a significant improvement in the above mentioned parameters was seen. In conclusion, safflower supplementation in diet of rats pointed out to a promising role of safflower, a natural product, on antioxidant enzymes, liver function and lipid profile of hyper-lipidemic rats, regardless if it is irradiated or not

    According to Indian Systems of Medicine, Spilanthes acmella (L.) Murr. (Family - Asteraceae), is considered effective in the treatment of sexual deficiencies especially due to ageing. In the present study, characterization of ethanolic extracts of the Spilanthes acmella flower and its effect on general mating pattern, penile erection and serum hormone levels of normal male Wistar albino rats were investigated and compared with sildenafil citrate. In vitro nitric oxide release was also investigated in human corpus cavernosum cell line. As N-alkylamides are a promising group, their profiling was performed using a gradient reversed phase high performance liquid chromatography/electrospray ionization ion trap mass spectrometry (HPLC/ESI-MS) method on an embedded polar column. MS(1) and MS(2) fragmentation data were used for identification purposes. For assessment of sexual behavior, animals were divided into five groups of eight male rats. The extracts (50, 100 and 150mg/kgbodyweight/day) and sildenafil citrate (5mg/kgbodyweight/day) (positive control) were administered orally for 28 days. The behavioral and sexual parameters were observed at days 0, 15, 28 and after a lapse of 7 and 14 days of discontinuance of drug treatment. Five N-isobutylamides, one 2-methylbutylamide and one 2-phenylethylamide were identified. The orally administered extract had a dose dependent positive effect on mounting frequency, intromission frequency and ejaculation frequency and the most significant effects (pacmella extract was demonstrated in vitro and in vivo. N-Alkylamides might attribute to the improved sexual potential. Study lends support to the traditional utilization of S. acmella as a sexual stimulating agent. PMID:21757328

  8. Protective Effect Of Garlic Oil On Some Neurotransmitters And Physiological Parameters In Male Rats Exposed To electro pollution

    International Nuclear Information System (INIS)

    Increasing exposure to electro pollution has become inevitable for people living in civilized and industrialized environments. This pollution can increase the production and life-span of free radicals which are causative factors in the oxidative damage of cellular structures and functions. This study evaluated the effects of exposure to electro pollution emitted from mobile base station on the oxidative status parameters, neurotransmitters, glycemic index and lipid profile in male rats and the protective role of garlic oil. Twenty four male albino rats were divided into three equal groups; group 1 served as control, group 2 exposed for 24 hr to electro pollution emitted from mobile base station founded on a roof of building for 4 weeks and group 3 exposed to electro pollution as group 2 then supplemented by stomach tube with garlic oil (250 mg/kg) for 4 weeks. Exposure to electro pollution caused significant increases in malondialdehyde (MDA) and nitric oxide (NO) while significant decreases in reduced glutathione (GSH) and catalase (CAT) were observed. Significant decrease in serotonin (5-HT) and significant increase in dopamine (DA) were also noticed with significant increase in serum glucose and significant decrease in insulin hormone. In addition, the lipid profile showed significant decrease in total cholesterol (TC) and high density lipoprotein-cholesterol (HDL-C) and significant increase in triglycerides (TG) and low density lipoprotein-cholesterol (LDL-C). Garlic oil supplementation ameliorates almost these disturbances leading to the conclusion that garlic oil exhibited significant protection against oxidative stress, neuro degeneration, hyperglycemia and hyperlipidaemia produced by electro pollution

  9. Whole body X-irradiation and impact of dietary factors on brain and testes of albino rats

    International Nuclear Information System (INIS)

    The study was undertaken to investigate the radioprotective effect of protein diet on the irradiated brain and testes. The study indicated that the less availability of protein in the diet caused a marked reduction in the protein and nucleic acid (DNA and RNA) contents of brain after irradiation. Further, the protein deficiency in diet brought about an increased deamination of protein in the brain of irradiated rats. It was noted that in response to irradiation the testes of protein deficient diet fed rats got adversely affected as compared to high protein diet fed animals. This paper gives evidence that feeding of protein enriched diet provides protection against ionizing radiation. (orig.)

  12. Evaluation of some hormonal levels related to age in adult and aged male rats exposed to gamma radiation

    International Nuclear Information System (INIS)

    As we grow older, the ability to produce most hormones in adequate amounts declined. This decline in natural hormones production coincides with nearly every age-related health problems. The present work aims to evaluate the levels of some hormones related to age namely dehydroepiandrosterone (DHEA), dehydroepiandrosterone sulphate (DHEA-s) and melatonin and also the alteration in lipid fractions using male rats subjected to acute sublethal dose of gamma radiation. This study included thirty two male albino rats divided into two main groups; adult group (four months old) and aged group (20 months old). Each group was divided into two subgroups; control group and group irradiated at a dose level of 5 Gray whole body gamma irradiation. Blood samples were collected from both adult and aged groups 3 days post-irradiation after 16 hours fasting. As related to age, the aged group showed significant decrease in DHEA, DHEA-s and melatonin levels and significant increase in total cholesterol, triglycerides, LDL-c and cholesterol/HDL ratio when compared to adult group. Concerning the effect of gamma radiation, the irradiated adult group showed significant (P<0.01) decrease in DHEA, DHEA-s and melatonin levels by values equal to -32.2%, - 39.8% and -67.9%, respectively, and nonsignificant changes in lipids concentrations except for LDL-c level, which showed significant (P<0.05) increase at +58.2 % in irradiated adult group as compared to adult controls. On the other hand, exposure to irradiation of aged rats did not affect the hormonal levels assayed except for the level of DHEA-s which was decreased significantly (P<0.05) by -26.4% as compared to control aged rats. Also, total cholesterol and LDL-c levels were increased significantly (P<0.01) by +17.1% and +27.4 %, respectively in irradiated rats as compared to control aged group. It could be concluded that y-radiation obviously accelerates the aging process in adults suggesting the need for protective agents to overcome the effects of ionizing radiation in exposed individuals

    International Nuclear Information System (INIS)

    The present study aimed to evaluate the capability of ? tocopherol (naturally occurring antioxidant) and zinc cysteine against radiation induced oxidative stress. ? Tocopherol was dissolved in corn oil and g, to the animals for ten successive days at a dose of 20 mg/kg b weight/day. Zinc cysteine was delivered to rats via intraperitoneal inject at a concentration of 25 mg/kg body weight/day for two successive days, rats were exposed to whole body gamma irradiation at a dose level of Gy. The activities of super oxide dismutase (SOD) and catalase and also concentrations of reduced glutathione (GSH) and malonaldehyde (Mi . were determined in the blood. The levels of metallothionein, zinc and copper were estimated in the serum, liver and kidney of the tested animals. The obtained results revealed that administration of a-tocopherol and zinc cysteine before gamma radiation exposure diminish significantly the decrease in blood SOD and catalase activities as compared to untreated irradiated rats. Also, the decrease in blood GSH concentration was less manifested and the decrease in the level of MDA was significant. The pre-gamma irradiation administration of zinc cysteine induced significant changes in the levels of metallothionein compared to both a-tocopherol supplemented and gamma irradiated rat groups. The amelioration occurred in the levels of zinc and copper postulated the positive role of vitamin E and zinc cysteine in alleviating all the levels of these elements

    In The Present investigation, oral administration of vitamin A of the therapeutic doses and double therapeutic doses (9.000 lU/kg b.wt and 18.000 IU/ kg body, wt) to female rats starting on day 1 up to day 19 of pregnancy and exposed to 3 Gy (1 Gy/3 times) whole body gamma irradiation on days 7th, 1th and 15th of gestation (dissection was preformed on day 20) caused morphological, histochemical and skeletal changes in pregnant rats and their foetuses. The congenital anomalies occurred in foetuses when pregnant rats were exposed to ?-irradiation including diminution of size and subcutaneous haemorrhage. On the other hand, miscellaneous malformations including kypophysis, exencephally, anophthalmia and deformation of ear region were designated in foetuses maternally treated with excess vitamin A. The malformations were severe when mothers were irradiated during vitamin A administration as manifested by macrocephaly and fusion of digits of the hind limb (Oligosyndactyly). The examination of the endo skeletal system of foetuses obtained from irradiated pregnant rats and treated with low or excess doses of vitamin A showed retardation in of the ossification of the skull bones and lack of ossification at the centre of vertebrae. Moreover, no ossification was observed in sternebra, metacarpals, metatarsals and phalanges. In the present study, the content of DNA exhibited significant decrease in mother irradiated and combined or not with vitamin A. The results are of great importance from the standpoint of radiation protection and drug safety

    Full Text Available Background Medicinal plants with natural antioxidants have been shown to be beneficial in a variety of complications such as anxiety. The elevated plus-maze (EPM is one of the most widely used models to assess anxiety in small rodents. Objectives This study was designed to characterize the anxiolytic-like activity of Borago officinalis (Linnaeus, family Boraginaceae or Borage flowers extract, using an EPM test. Materials and Methods Male Wistar rats weighing 220-250 grams were used in the present study. Thirty minutes after an intraperitoneal (IP injection of the Borage extract (50, 100, 200 mg/kg or saline, each animal was placed in the EPM. Animal behaviors in the experimental sessions were recorded by a video camera located above the maze, interfaced with a monitor and a computer in an adjacent room. The time spent in the open arms, the percentage of entries into the open arms of the EPM and the numbers of entries into the closed arms were recorded for five minutes. Results Statistical analysis indicated that acute IP injection of Borage extract before an EPM trial significantly increased the time spent in open arms and percentage of open arms entries. Whereas, the extract had no effect on the number of closed arm entries. Conclusions Our results demonstrated that injection of Borage extract might have an anxiolytic profile in rats. However, the exact mechanism (s related to the active compound (s in Borage extract should be elucidated in future studies.

    Full Text Available This study was designed to detect the effects of aluminum chloride AlCl3 on some pathophysiological features of adult male rats. Eighteen rats were divided to 3 groups of 6 animals each. These included untreated control and 2 treated groups received AlCl3 at the doses 40 and 80 mg/kg of body weight, orally and daily for 30 days. The following parameters were recorded: Body weight (weekly, central nervous system activity tests (weekly, hematological examinations at 15 and 30 days of experimentally and gross and histopathology for brain, liver, kidneys and heart at the day (30. The results showed a significant decrease in body weight mean of 3rd group (80 mg/kg at 4th week, a significant decrease in the activity associated with time progress in experiment by recording (moving onset, square crossed and rearing in 3 minutes, negative geotaxis tests, there were no significant differences between groups at pack cell volume and hemoglobin concentration with a significant decrease in total leukocyte count at 2nd group (40 mg/kg. Differential leukocyte count revealed significant increase in lymphocyte at day 30. Histopathological changes were neuronal vaculation and proliferation of microgelial cells in brain, vacular degeneration and lymphocytic infiltrations in hepatic parenchyma with mild portal fibrosis in liver, at kidneys there were cloudy swelling, coagulative necrosis to the renal tubular epithelium, more severely noticed at 3rd group, no pathological changes were noticed at myocardium and coronary arteries at both treated groups.

    Female rats exhibit greater intake and motivation to self-administer cocaine. In females but not males, isolation by itself is a stressor, which could lead to increased drug intake. Therefore, we hypothesized that social housing would buffer against stress and reduce the motivation to self-administer cocaine primarily in females. Male and female Sprague-Dawley rats were housed individually or in same-sex pairs. The individually housed rats and one of each pair were allowed to self-administer ...

    Full Text Available The role of oxidative stress in cisplatin (CP toxicity and its prevention by pretreatment with selenium (Se was investigated. Male Wistar albino rats were injected with a single dose of cisplatin (7.5 mg CP/kg b.m., i.p. and selenium (6 mg Se/kg b.m, as Na2SeO3, i.p. alone or in combination. The results suggest that CP intoxication induces oxidative stress and alters the glutathione redox status: reduced glutathione (GSH, oxidized glutathione (GSSG and the GSH/GSSG ratio (GSH RI, resulting in increased lipid peroxidation (LPO in rat liver. The pretreatment with selenium prior to CP treatment showed a protective effect against the toxic influence of CP on peroxidation of the membrane lipids and an altering of the glutathione redox status in the liver of rats. From our results we conclude that selenium functions as a potent antioxidant and suggest that it can control CP-induced hepatotoxicity in rats.
