PROTECTION ROLE OF CALCIUM THERAPY IN IRRADIATED MALE ALBINO RATS  

International Nuclear Information System (INIS)

Free oxygen radicals and insufficiency of antioxidant enzymes have been implicated in the pathogenesis of radiation syndrome. The trace elements are functioning as co-factors in antioxidant enzymes. The antioxidant system and trace elements have been investigated in many different studies including tissue repair processes but this study deal with radiation injury in male albino rats.The study was carried out to investigate the beneficial role of the used metallo element as radio-protector due to its ability for chelating free radicals produced by ionizing radiation. The efficacy of daily oral treatment of rats with calcium glubionate (daily 6 mg/kg body wt) for 6 successive days to control many of the damaging effects of ionizing radiation when these rats subjected to 6 Gy whole body gamma ray were studied. The activity of catalase (CAT) and levels of total cholesterol (TC), triacylglycerols (TG) and malondialdehyde (MDA) in serum were determined. In addition, CAT activity and contents of reduced glutathione (GSH) and MDA in liver, kidney and spleen tissues of control, calcium treated, irradiated and protected rat groups were evaluated. Samples were collected from animals 24 hours after end of the Ca- glubionate treatment or exposure to gamma radiation. The data obtained revealed that, radiation exposure caused significant alterations in all tissues and serum biochemistry. On the contrary, neutralization was occurred in these biochemical aspects in protected animal grbiochemical aspects in protected animal groups due to Ca-glubionate treatment. In conclusion, Ca-glubionate could protect rats against biochemical alterations associated with gamma ray oxidative stress. These effects were explained in the light of the presumed different mechanisms of Ca-glubionate

International Nuclear Information System (INIS)

Levanox, a hepato protective drug, and garlic powder have been considered as safe anti-oxidant agents. The present investigation refers to biochemical and molecular studies to evaluate the protective role of levanox and/or garlic powder toward CCl4-induced toxicity in adult male albino rats. CCl4 intoxication was attempted using a dose of 0.03 ml/kg of rat body weight.Pre-treatment with levanox (one capsule/ kg of rat body weight, each capsule contains 100 mg catechu, 7.5 mg dandelion, 75 mg termiric 2% curcumin, 17.5 mg silymarin, 100 mg lecithin) was more effective than garlic powder (100mg/kg of rat body weight) in reducing CCl4-induced hepatotoxicity as revealed by its higher potency in reducing elevation of aspartate (AST) and alanine (ALT) aminotransferases in serum. Serum of control rats and those treated with levanox or garlic or CCl4 produced 13 types of proteins, differing in the molecular weight (MW) and densities, while those of levanox + garlic or garlic +CCl4 produced 14 bands differing in the MW and densities. The similarity index at the epigenetic level was also studied using the primers under study. The control sample produced one amplified DNA fragment with Rf of 0.73 and a molecular size (MS) of 67 base pair (bp) . Using the same primers, no amplified DNA fragment with the same MS was produced in the sample taken from levanox + garlic treated group.OPA-2 primer of sequence 5?- AGA TGC AGC C-3? produced one amplified DNA band wiGC C-3? produced one amplified DNA band with MS of 292 bp and Rf of 0.46 . However, the same primer produced one amplified DNA characteristic band with a molecular size of 363 bp and Rf of 0.43 in the sample of levanox + garlic group.In the control sample, OPA-4 primer of sequence 5? - ACG CAC AAC C-3? produced one amplified DNA band of MS of 299 bp and Rf of 0.43. The same primer produced one amplified characteristic DNA band with MS of 363 bp and Rf of 0.43 in the sample of levanox + garlic group.Dual treatment with levanox and garlic powder resulted in a characteristic protein differing from that of control as revealed through SDS-PAGE and confirmed by RAPD-PCR

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

Traffic Noise: A Silent Killer of Male Gamate of Albino Rats  

Directory of Open Access Journals (Sweden)

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.

Biochemical and immunological changes on oral glutamate feeding in male albino rats  

Science.gov (United States)

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.

Directory of Open Access Journals (Sweden)

Full Text Available Triphenylantimony(V derivative, Ph3Sb(OPri[SC6H4N:C(CH3CH2C(OCH3], 1b, and the corresponding benzothiazoline ligand [1, 2], HNC6H4SC︹(CH3CH2C(OCH3, 1a, have been tested for their effects on the reproductive system of male albino rats. The oral administration of both 1a and 1b at the dose level of 10 mg/rat/day produced significant reduction in the weights of testes, epididymides, seminal vesicles, and ventral prostate. Significant decrease in sperm motility as well as in sperm density resulted in 100% sterility. Significant (P<.01 alterations were also found in biochemical parameters of reproductive organs in treated male rats as compared to the control group. Production of preleptotene, pachytene, and secondary spermatocytes was decreased by 42%, 43%, 39%, and by 44%, 49%, 55% in the ligand, 1a, and organoantimony(V derivative, 1b, treated rats, respectively. These results indicate that both compounds 1a and 1b are antispermatogenic in nature and on oral administration in male rats, and finally caused sterility. A comparison indicates that the organoantimony(V derivative 1b is more effective pertaining to its antispermatogenic activity than the corresponding ligand 1a.

ANTIOXIDANT ACTIVITY OF MELATONIN AGAINST GAMMA OR ULTRAVIOLET IRRADIATION HAZARDS IN MALE ALBINO RATS  

International Nuclear Information System (INIS)

Irradiation has been widely reported to damage organisms by attacking proteins, nucleic acids and lipids in cells. However, low dose irradiation has become the focus of research in radiobiology in recent years. This study was undertaken to analyze changes in blood levels of immunoreactive aminoterminal propeptide of type III procollagen (PIIINP), total antioxidant capacity, protein and albumin levels in male albino rats exposed to ultraviolet-type C (UV-C) or low dose of gamma radiation. The role of melatonin, as an antioxidant agent, in restoring the serum levels of the selected biochemical parameters after irradiation was studied in male rats exposed to the two types of radiation. Gamma irradiation as a single dose of 2 Gy resulted in significant decreases in serum total protein, albumin, total antioxidant capacity and serum PIIINP level in male rats as compared to control. One hour ultraviolet irradiation/day for 3 weeks resulted in significant increase in serum total protein and significant decreases in PIIINP and total antioxidant capacity as compared to control.Statistical analysis revealed that intraperitoneal injection of 10 mg melatonin/kg body weight after UV or gamma irradiation restored the levels of the selected serum biochemical parameters as compared to control rats

Some Neuro hormonal Effects of ruta chalepensis in adult male albino rats  

International Nuclear Information System (INIS)

Oral sub-chronic administrations of Ruta chalepensis extract equivalent to 3.0 g/kg body weight were given to male albino rats daily for four weeks (0.5 ml solution/100 g/ rat). The data revealed significant increases in tyrosine, dopamine (DA) and norepinephrine (NE) in all tested brain areas throughout most of the experimental intervals. Significant increases of serum leutinizing hormone (LH) and testosterone were also observed while serum prolactin was decreased significantly. It could be also concluded from the present results that treatment with Ruta chalepensis extract significantly increased catecholamine content. This observation may be in part due to an increase in its synthesis through an increase of the peripheral availability of tyrosine for brain synthesis of catecholamine and/or a decrease in its release

Zinc sulphate and vitamin E alleviate reproductive toxicity caused by aluminium sulphate in male albino rats.  

Science.gov (United States)

This study was designed to investigate the reproductive toxicity of aluminium sulphate and the therapeutic effects of administration of zinc sulphate and vitamin E individually or in combination against the toxic effect caused by aluminium (Al) in male albino rats. The animals were divided into five groups: group 1 received distilled water and served as control; group 2 received only aluminium sulphate (50 mg/kg body weight (b.w.)); group 3 received aluminium sulphate (50 mg/kg b.w.) plus zinc sulphate (50 mg/kg b.w.); group 4 received aluminium sulphate (50 mg/kg b.w.) and vitamin E (15 mg/kg b.w.); group 5 received aluminium sulphate plus a combination of zinc sulphate and vitamin E in similar doses as above. Doses were administered orally once daily for 45 consecutive days. The results revealed that aluminium sulphate induced significant decrease in body weight gain and testis weight and significant increase in Al level in both serum and testes of male rats. Biochemical analysis showed significant decrease in serum total protein and phospholipids levels, while serum total lipid was significantly elevated post Al treatment. In addition, significant decrease in total protein, phospholipids and cholesterol levels in the testes of Al-treated rats was recorded. The data also showed significant decrease in the levels of serum testosterone, leutinizing hormone and follicle stimulating hormone and significant increase in the level of serum prolactin in Al-intoxicated rats. Moreover, histological examination showed that aluminium sulphate caused apparent alterations in the testicular structure of the treated animals. Treatment with zinc sulphate and vitamin E individually or in combination ameliorated the harmful effects of Al, which was proved histopathologically by the noticeable improvement in the testicular tissues. We can conclude that the tested dose of aluminium sulphate induced toxic effect on the reproductive system of male albino rats and the treatment with zinc sulphate and/or vitamin E alleviated these toxic effects. In some cases, vitamin E exerted a more potent effect, while in other cases, the more potent effect is related to zinc sulphate and the combination of both at most of the recorded data.

A comparative study on aphrodisiac activity of some ayurvedic herbs in male albino rats.  

Science.gov (United States)

The roots of Asparagus racemosus, Chlorophytum borivilianum, and rhizomes of Curculigo orchioides are popular for their aphrodisiac and immunostimulatory properties. The herbs have been traditionally used as Vajikaran Rasayana herbs because of their putative positive influence on sexual performance in humans. Lyophilized aqueous extracts obtained from the roots of A. racemosus, C. borivilianum, and rhizomes of C. orchioides were studied for sexual behavior effects in male albino rats and compared with untreated control group animals (total N = 60). The rats were evaluated for effect of treatments on anabolic effect. Seven measures of sexual behavior were evaluated. Administration of 200 mg/kg body weight of the aqueous extracts had pronounced anabolic effect in treated animals as evidenced by weight gains in the body and reproductive organs. There was a significant variation in the sexual behavior of animals as reflected by reduction of mount latency, ejaculation latency, post ejaculatory latency, intromission latency, and an increase of mount frequency. Penile erection (indicated by Penile Erection Index) was also considerably enhanced. Reduced hesitation time (an indicator of attraction towards female in treated rats) also indicated an improvement in sexual behavior of extract treated animals. The observed effects appear to be attributable to the testosterone-like effects of the extracts. Nitric oxide based intervention may also be involved as observable from the improved penile erection. The present results, therefore, support the folklore claim for the usefulness of these herbs and provide a scientific basis for their purported traditional usage. PMID:19139984

Biochemical evaluation of low dose methyl 2-benzimidazole carbamate fungicide on male albino rats  

Directory of Open Access Journals (Sweden)

Full Text Available

Methyl 2-benzimidazole carbamate (carbendazim is one of the synthetic fungicides that controlled organisms that caused plant diseases of different types. It is widely used as a preservative in leather, paint, textile, fruits and papermaking industry. It is also used as an anticancer drug in chemical medicine. In the present study low concentrations of carbendazim was administered at 5, 10, 25 and 50mM doses intradermally to male albino rats. At the end of 6 hr, 12hr and 24hr duration, blood samples were collected from the animal for the analysis of biochemical and haematological parameters. Carbendazim caused an increase of cholesterol, uric acid, glucose and creatinine while serum phosphorous content was decreased. However, mean hemoglobin, WBC, E, and platelet counts increased and total RBC, N and L counts decreased. These results indicated that low dose level carbendazim contributed to toxicological effects in the rat tissues.

International Nuclear Information System (INIS)

Thirty adult male albino rats were used in the present study to assess the effect of using tryptophan or/and hawthorn extract with coenzyme Q 10 in ameliorating the effect of high fat diet (HFD) intake on hyperlipidaemia, hormonal imbalance and body weight. Six animals were served as a control group while the other twenty four rats were supplemented with 20 g butter/100 g standard laboratory diet (HFD) for 8 weeks prior to the experiment. These HFD rats were divided randomly into four equal groups; hyperlipidaemic group, tryptophan and hawthorn groups where animals of the latter two groups were supplemented with 100 mg/kg B.W. tryptophan and 50 mg/100 g B.W. hawthorn extract respectively, and mixed group that was daily administrated with a mixture of 100 mg/kg B.W. tryptophan, 50 mg/100 g B.W. hawthorn extract and 50 mg/kg B.W. coenzyme Q10. Body weight was recorded twice/week, after 30 days animals were decapitated and sera were collected for determination of total lipids, triglycerides, total cholesterol, high density lipoprotein (HDL), low density lipoprotein (LDL), triiodothyronine (T3), Thyroxine (T4), testosterone and corticosterone hormones. The data revealed that tryptophan, hawthorn extract alone or mixed with CoQ10 improved the dreadful effects induced by HFD, but the most profit was achieved by mixing these three antioxidants on hyperlipidaemia, tested hormones and body weight.

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

International Nuclear Information System (INIS)

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 vitamieriods (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

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 assortss 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.

Spermatoxic effects of operation sweep herbal supplement in male albino rats.  

Science.gov (United States)

Operation Sweep (OPS) de rheumatism powder is a registered Nigerian poly-herbal medicine. The acute and sub-chronic testicular toxicology of the OPS powder was investigated in male albino rats. The rats, divided into 10 per group, received aqueous extract of the OPS powder, orally, at 0, 0.75, 1.50, 2.25 g/kg for 30 days. Animals were sacrificed on day 30; the testes and epididymis were excised and weighed. The testes were processed for histological analysis, and the epididymis was used for sperm quality: epididymal sperm count (ESC), epididymal sperm motility (ESMot) and the epididymal sperm morphology (ESMor) determination. The results showed a non-significant increase in the body weights of the treated groups. Treatment with OPS caused a significant (p .05) effect on the ESMor. Histologic examination of the testes indicated no serous pathological changes except for some mild vascular congestion at 1.5 and 2.25 g/kg. This study suggests that the aqueous extract of the OPS powder may cause epididymal toxicity as shown in the adverse effect on sperm quality. PMID:20853597

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

Directory of Open Access Journals (Sweden)

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.

Fifty male albino rats were used in this study to correlate liver function after curcumin or/and malathion intake with the levels of immunoglobulin G (IgG) and immunoglobulin M (IgM). The rats were divided into four groups, the first was the control group, the second was given malathion in drinking water (200 ppm), the third was administrated curcumin orally (70 mg/kg b.w.) 5 times /week while the fourth group received both malathion and curcumin with the same previous concentrations. Liver state was evaluated every 10 days by estimating prothrombine time (P.T.) and concentration (PC) and albumin level from blood taken from the retroorbital vein of 5 rats of the malathion group. After 40 days when there is prolongation of P.T. and hypoalbuminemia, ten rats from each group were decapitated. Liver enzymes, total protein, glucose, insulin, IgG and IgM were estimated. The data revealed that there is an increase of liver enzymes, glucose, insulin, and immunoglobulins (IgG) and (IgM) in malathion group and positive correlation between liver enzymes and immunoglobulins. These results denoted that the increase of immunoglobulins after malathion intake had no beneficial effects on the prognosis of liver condition, on the contrary, it may worsen liver state if there is some element of auto immunity, as well as the study proved that turmeric has the potential to improve the toxic effects of Malathion, whether on the functions of the liver or immune globulins.r or immune globulins.

Physiological Changes Induced by Long Term Administration of Saccharin Compared with Aspartame to Male Albino Rats  

Directory of Open Access Journals (Sweden)

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.

Effects of Carbaryl and Deltamethrin Pesticides on Some Pituitary Hormones of Male Albino Rats  

International Nuclear Information System (INIS)

This investigation aims to study the effects of oral administrations of 1/10 LD50 of both carbaryl and deltamethrin pesticides on some pituitary hormones of male rats namely; adrenocorticotropic hormone (ACTH), thyroid stimulating hormone (TSH), growth hormone (GH), beta-endorphin (b-end) and prolactin hormone (prol). At different time intervals of 1,3,7 and 10 days, blood samples were collected and sera were separated and analyzed for hormonal assessment using RIA technique. The data clarified that daily oral administrations of 1/10 LD50 of both carbaryl (28.6 mg/kg body weight) and deltamethrin (12.8 mg/kg body weight) to male albino rats resulted in gradual and significant decreases in serum ACTH recording 70.60% and 71.75% as compared to control on the 10''th day of carbaryl and deltamethrin treatments, respectively. Similarly, serum TSH and GH levels were significantly decreased one day after treatment showing their maximum decreases on the 10th day recording 30.09% and 40.25% for TSH and 43.84% and 41.47% for GH after treatment with carbaryl and deltamethrin, respectively. Moreover, serum b-endorphin level showed maximum and significant decreases of 29.47% and 33.28% on day 10 of treatment with carbaryl and deltamethrin, respectively. On the other hand, serum prolactin level was significantly increased one day after treatment showing its maximum increase at the end of the experimental period recording 92.06% and 84.52%imental period recording 92.06% and 84.52% for carbaryl and deltamethrin, respectively. From the present data, it could be suggested that the pituitary gland is a major target for the two pesticides carbaryl and deltamethrin which have the potential to influence the modulation of endocrine system via the hypothalamus pituitary axis

Acute Effect of Sidr Leaves Extract on some Neurotransmitter Contents in Different Brain Areas of Male Albino Rats  

International Nuclear Information System (INIS)

The acute i.p. injection of Sidr ( Zizyphus spina-christi) leaves extract ( 100 mg / kg body wt ) caused a significant increase in epinephrine (E), norepinephrine (NE), dopamine (DA), serotonin (5-HT), 5-hydroxiindoleacetic acid (5-HIAA) and a significant decrease in gamm-aminobutyric acid (GABA) content in different brain areas (cerebellum , pons plus medulla oblongata, striatum, cerebral cortex, hypothalamus, midbrain and hippocampus) of male albino rats. The increase in E, NE, DA, 5-HT, and 5-HIAA content in the different CNS areas of albino rat may be due to the inhibition of Ca2+/calmodulin binding which plays an important role in the release of these neurotransmitters, at the same time GABA inhibits the release of these neurotransmitters by increasing the permeability to Cl ions and such effect may be due to the presence of peptide and cyclopeptide alkaloids in the extract. Zizyphus spina-christi leaves may potentially be safe for use as a sedative drug. (author)

PROTECTIVE EFFECT OF N-ACETYLCYSTIENE AGAINST TITANIUM DIOXIDE NANOPARTICLES MODULATED IMMUNE RESPONSES IN MALE ALBINO RATS  

Directory of Open Access Journals (Sweden)

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.

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 exps (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

Ameliorative Effects of Acacia Honey against Sodium Arsenite-Induced Oxidative Stress in Some Viscera of Male Wistar Albino Rats  

Science.gov (United States)

Cancer is a leading cause of death worldwide and its development is frequently associated with oxidative stress-induced by carcinogens such as arsenicals. Most foods are basically health-promoting or disease-preventing and a typical example of such type is honey. This study was undertaken to investigate the ameliorative effects of Acacia honey on sodium arsenite-induced oxidative stress in the heart, lung and kidney tissues of male Wistar rats. Male Wistar albino rats divided into four groups of five rats each were administered distilled water, Acacia honey (20%), sodium arsenite (5?mg/kg body weight), Acacia honey, and sodium arsenite daily for one week. They were sacrificed anesthetically using 60?mg/kg sodium pentothal. The tissues were used for the assessment of glutathione peroxidase, catalase, and superoxide dismutase activities, protein content and lipid peroxidation. Sodium arsenite significantly (P < 0.05) suppressed the glutathione peroxidase, catalase, superoxide dismutase activities with simultaneous induction of lipid peroxidation. Administration of Acacia honey significantly increased (P < 0.05) glutathione peroxidase, catalase, and superoxide dismutase activities with concomitant suppression of lipid peroxidation as evident by the decrease in malondialdehyde level. From the results obtained, Acacia honey mitigates sodium arsenite induced-oxidative stress in male Wistar albino rats, which suggest that it may attenuate oxidative stress implicated in chemical carcinogenesis.

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. Ht day 21 after melatonin injection. However, melatonin ameliorated the elevated TSH level induced by ?-irradiation to reach its corresponding control value at day 21

Impact of ?-tocopherol on Metronidazole and Tetracycline-induced Alterations in Reproductive Activities of Male Albino Rats  

Directory of Open Access Journals (Sweden)

Full Text Available Antimicrobial drugs have been reported to have adverse effects on male fertility. The present study reports the role of ?- tocopherol on metronidazole and tetracycline induced reproductive alterations in albino rats. Male albino rats (5/group were treated with 20 mg kg-1 bw day-1 metronidazole or 60 mg kg-1 day-1 tetracycline with or without 15 mg kg-1 bw ?-tocopherol for 8 weeks. The reversibility of effects after 4 weeks recovery period was determined in separate groups of 5 rats. The control groups received distilled water (vehicle and 15 mg kg-1 day-1 ?- tocopherol for 8 weeks. Metronidazole and tetracycline significantly (p<0.05 reduced the weight of the epididymis, sperm count, motility and serum testosterone levels and increased the activity of endogenous superoxide dismutase (SOD in the testis. Alpha-tocopherol significantly (p<0.05 decreased the weight of the testis, epididymis, sperm motility and serum testosterone levels. Co-administration of metronidazole or tetracycline with ?-tocopherol caused significant restoration in sperm indices and SOD activity while it produced no effect on testosterone secretion. The results suggest that the effects of metronidazole and tetracycline on male reproductive functions, which are partially reversible, could be mediated via a reduction in serum testosterone level and probably also via the free radical generating mechanism.

Hormonal Profile And Histopathological Study On The Influence Of Silymarin On Both Female And Male Albino Rats  

Directory of Open Access Journals (Sweden)

Full Text Available Silymarin is a mixture of flavonoids extracted from seeds of milk thistle (Silybum marianum [L] Gaertn . Extracts of S. marianum have been used in the treatment of liver diseases for more than 2000 years. Flavonoids are a large group of polycyclic phenols of plant origin. Flavonoids displaying estrogenic effects (phytoestrogen. Phytoestrogens show an estrogenic activity owing to the structural similarity with the estrogen skeleton ,mimicking natural estrogens, it binds to estrogen receptor and modulates its activity . These effects cause complex changes inducing a shift in an overall hormonal balance of the individual. Long term intake of feeds with a higher content of phytoestrogens can induce transient or permanent infertility. Silybum marianum leaves have been traditionally used in Egypt for their antifertility effects .Also, the antifertility property of silybum marianum leaves was investigated in female albino rats. This property highlights the impotance to clarify the role of silymarin (420mg /day a human therapeutic dose on both female and male albino rats. Silymarin (151.2 mg/kg BW prevented pregnancy in adult female albino rats on days 1-5 post coitum. In female rats the follicle stimulating hormone (FSH displayed marked increase, while the luteinizing hormone (LH and estradiol remained within normal levels. These results showed a distinct increase in number and size of ovarian growing follicles while the effect of silymarin on the uterine wall was in the form of hypertrophy of endometrial epithelium, also increase in the number of uterine glands. Ovaries taken from females treated with silymarin for one and two months contained a large number of growing follicles. In male rats treated with silymarin (151.2 mg/kg BW for one month, testosterone and LH were increased significantly, meanwhile estradiol not changed. Testes of rats treated with silymarin for one month showed well developed spermatogenesis with lot of sperms. The epididymis of the same group contained a heavy number of sperms. While rats treated with silymarin for two months displayed significant decrease in serum testosterone levels, while LH and estradiol not changed. These rats displayed some tubules contained well developed spermatogenic layer and normal leyding cells, others appeared moderated by affected. The epididymis contained less number of sperms. These results indicated that silymarin (151.2mg /kgBW a dose equivalent to human therapeutic dose (420mg/ day prevented pregnancy in female rats and caused some histological changes in the ovary and uterus, while it has biological benefits for male rats during short treatment.

ABHRAK BHASMA MEDIATED ALTERATIONS IN LIVER AND KIDNEY FUNCTIONS IN MALE ALBINO RATS DURING CARBON TETRACHLORIDE INDUCED TOXICITY  

Directory of Open Access Journals (Sweden)

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.

Antilithiatic effect of Asparagus racemosus Willd on ethylene glycol-induced lithiasis in male albino Wistar rats.  

Science.gov (United States)

The ethanolic extract of Asparagus racemosus Willd. was evaluated for its inhibitory potential on lithiasis (stone formation), induced by oral administration of 0.75% ethylene glycolated water to adult male albino Wistar rats for 28 days. The ionic chemistry of urine was altered by ethylene glycol, which elevated the urinary concentration of crucial ions viz. calcium, oxalate, and phosphate, thereby contributing to renal stone formation. The ethanolic extract, however, significantly (p < 0.05) reduced the elevated level of these ions in urine. Also, it elevated the urinary concentration of magnesium, which is considered as one of the inhibitors of crystallization. The high serum creatinine level observed in ethylene glycol-treated rats was also reduced, following treatment with the extract. The histopathological findings also showed signs of improvement after treatment with the extract. All these observations provided the basis for the conclusion that this plant extract inhibits stone formation induced by ethylene glycol treatment. PMID:16357948

International Nuclear Information System (INIS)

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 resultsliorates 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

The Protective Effects of Vitamin E and Zinc Supplementation Against Lithium-Induced Brain Toxicity of Male Albino Rats  

Directory of Open Access Journals (Sweden)

Full Text Available Lithium (Li therapy has widely used in the treatment of bipolar disorder. Consequently, consciousness of the side effects and pathogenesis of this metal is needed for such treatments. Recently, information on the interaction of Li with oxidative markers and organs toxicity attend the researchers over the world. In the present study we have tried to evaluate the influence of oral administration of LiCl for 4 weeks on the oxidative stress marker and histological structure of brain in male rats. Fifty adult male albino rats weighing 135±15 gm was categorized into 5 groups (10 rats each. Group I worked as negative control, group II administrated with LiCl (0.20 mg/kg bw in drinking water, group III, IV and V were administrated with Zn (10 mg/kg bw, VE (100 mg/kg bw and their combination twice a week besides the daily administration of LiCl for 4 weeks, respectively. Rats after anesthesia with ether killed for collocation of brain for histopathological and biochemical analysis. Data obtained showed a significant increase in LPO, NO, GSH and Li content and the activities of SOD, CAT and AChE with demylination of the nerve fibers and degeneration of neurons in brain of LiCl treated rats. Co-treatment of rats with Zn or VE results in a significant decrease in LPO, NO, GSH content in the activities of SOD, CAT and AChE with less or normal structure of the brain. However, co-treatment with combination of Zn and VE caused a significant increase in SOD, CAT and AChE activities with normal histological structure.In conclusion, the data from the present study show that Zn and VE and their interaction are effective in protection against Li- induced brain toxicity in rat with priority for the combination.

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 improvemalbumin. 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

Science.gov (United States)

To control growing world population, there is a need for male contraceptive methods that are comparable to female contraceptives, but due to lack of knowledge or investigation, no sufficient safe and effective contraceptives were developed till now. In the present investigation, the effect of 100% methanol extract of Opuntia dillenii phylloclade on reproduction in male rats was studied. A first group (I) received vehicle alone to serve as control. The second group (II) was further divided into treated and recovery groups, and the plant extract at 50 mg kg body weight(-1) was administered orally for 30 days. Biochemical, haematological and histopathological analyses were carried out to reveal the effects on reproductive organs in the male rats. The weights of reproductive organs were recorded. It was found that the number of fertile males, number of inseminated females, number of litters delivered and testosterone levels were reduced significantly. Epididymal sperm count and motility were also significantly decreased. Biochemical parameters support the antifertility activity of O. dillenii i.e. decreases in protein, glycogen content and elevation in cholesterol level. Testes and sperm morphology were altered significantly. Haematological parameters have not shown any significant changes. It is concluded that 100% methanol extract of O. dillenii possesses antifertility effects on male reproduction without change in general physiology. PMID:21950638

The Use of Statin Substitutes to Improve the Lipid Profile in Liver Dysfunctional Male Albino Rats  

International Nuclear Information System (INIS)

More attention has been drawn to different strategies for prevention of cardiovascular associated with liver dysfunction. The aim of the present study is to compare between statin and free fat- milk supplemented with multivitamins in hyperlipidaemic male rats with or without liver dysfunction induced by CCl4. The animals were allocated to 7 equal experimental groups (16 rats each): control group, hypercholesterolemic group, hypercholestero-lemic-statin group, hypercholesterolemic-free fat milk-multivitamins group, hypercholesterolemic-CCl4 group, hypercholesterolemic-CCl4-statin group, and hypercholesterolemic-CCl4- fat-free milk-multivita-mins group. After one month half of the rats of each group were decapitated and the rest of the animals were decapitated after two months. Lipid profile, relative liver weight, liver function, CPK and LDH were determined. The effectiveness of statin drug in the management of blood lipids was confirmed without improving or worsening liver functions. Meanwhile, this effectiveness worsened in hypercholesterolemic rats treated with CCl4 as compared to hypercholesterolemic group. Administration of fat-free milk with multivitamins, as an alternative remedy for statin drug, has improved lipid profile in hypercholesterolemic rats and it revealed no changes in liver enzymes in hypercholesterolemic rats with liver dysfunction indicating the favorable use of them as hypolipotropic agent without affecting liver metabolismng liver metabolism

Chronic stress and carbohydrate metabolism: persistent changes and slow return to normalcy in male albino rats.  

Science.gov (United States)

The present study tested the hypothesis that long-term repeated exposure to stressors results in irreversible changes in carbohydrate metabolism. Groups of adult male rats (five per group) were restrained for 1 h and 4 h later were forced to swim for 15 min everyday for 2, 4, or 24 weeks; five rats were autopsied after each interval. Groups of five rats exposed to stress for 2 or 4 weeks were maintained without further treatment (recovery groups) for up to 24 weeks. The fasting blood glucose concentration, measured at weekly intervals, was significantly higher in the stressed rats than in controls throughout the experiment, except in the 24th week, whereas that of the recovery groups was significantly higher than controls only up to the 8th week after the end of stress exposure and then reached normalcy. The blood concentrations of glucose, lactate, and pyruvate were significantly higher in the 2 and 4 weeks stress groups than in controls, whereas, except for lactate, in rats stressed for 24 weeks these values did not significantly differ from those in controls. These changes were accompanied by increased gluconeogenesis and glycogenolysis as shown by alterations in activities of hepatic carbohydrate metabolizing enzymes and unaltered blood insulin concentrations in rats stressed for 2, 4, and 24 weeks. Furthermore, the blood insulin levels did not significantly vary among controls and the 2, 4, and 24 weeks stress groups. The results reveal that though hyperglycemia induced by long-term stress exposure is reversible, it persists for a prolonged period, even after the termination of stress exposure, before reaching normalcy. Prevalence of hyperglycemia for a prolonged period through increased activities of hepatic enzymes in stressed rats exemplifies allostasis. PMID:21992064

Protective Role of Carnitine against the Harmful Biological Effects of Paracetamol and Radiation Exposure in Male Albino Rats  

International Nuclear Information System (INIS)

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 amie 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

Effect of deltamethrin on transmission of gamma aminobutyric acid (GABA) and thyroid hormones in adult male albino rats  

International Nuclear Information System (INIS)

The oral administration of 1/5 LD50 of deltamethrin for 15 days produced an increase in GABA content and a decrease in Cl- ions concentration in all tested brain areas (cerebellum, pons + medulla oblongata, striatum, cerebral cortex, hypothalamus, midbrain and hippocampus) of adult male albino rats, almost at most time intervals. Deltamethrin also resulted in a significant decrease in serum TSH and increase in T3 and T4 levels in the treated rats. From the present results, it was found that deltamethrin decreased the passage of Cl- ions in the cells which might be, in part, due to a decrease of the transmission of GABA and an increase of the circulating thyroid hormones (triiodothyronine and thyroxine). Accordingly, deltamethrin may act as GABA antagonist and may act on the hypothalamus pituitary thyroid axis. In conclusion the elevation of thyroid hormones as well as the decrease in both CL- ions and GABA transmission which could be all together responsible for the impairment of motor activity, hyper excitability and seizure that occurred in rats treated with the pyrethroid insecticide deltamethrin

The aim of the present study was to investigate the daily effect of valerian (Valeriana officinalis L .) root extract on epinephrine (E), norepinephrine (NE), dopamine (DA), serotonin (5-HT) and 5-hydroxyindoleacetic acid (5-HIAA) , and gamma-aminobutyric acid (GABA) contents in different brain areas (cerebellum , pons plus medulla oblongata , striatum , cerebral cortex, hypothalamus, midbrain and hippocampus) of male albino rats .The daily intraperitoneal ( i.p.) injection of 300 mg/kg body wt valerian for 30 days caused a significant increase in epinephrine ( E ) content in pons plus medulla oblongata, cerebral cortex , hypothalamus and in midbrain . Norepinephrine (NE ) content was significantly increased in all brain areas tested except in cerebellum and cerebral cortex . Dopamine (DA) content was significantly increased in all tested brain areas except in cerebral cortex and hippocampus . moreover , there was also a significant increase in serotonin (5-HT ) and 5-hydroxyindol acetic acid (5-HIAA) contents in all tested brain areas . However, gamma-aminobutyric acid (GABA) content was significantly decreased in all tested brain areas . After the extract withdrawal, the increase in ( E, NE, DA , 5-HT ) contents and the decrease in GABA content persisted in pons plus medulla oblongata , striatum , midbrain and hippocampus , and this might be due to regional differences toward the effect. The increase in E, NE, DA , 5-HT and 5-HIAA contents, at the same time the decr5-HIAA contents, at the same time the decrease in GABA content in the different brain areas of albino rats may be due to the presence of both valepotriates and valerenic acid in the extract which mediated the GABA ergic mechanisms including the inhibition of GABA metabolism and the increase in GABA synthesis and release , although agonized the GABAA receptors which led to the inhibit of the neurotransmitter release. Valerian root extract may be useful as a herbal medicine having sedative effect and it is safe. (author)

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 significann 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.

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.

protective effect of certain vitamins against radiation-induced biochemical and histological changes in kidney of male albino rats  

International Nuclear Information System (INIS)

Ionizing radiation is a potent mutagenic and carcinogenic agent due to the liberation of free radicals. It is, therefore, essential to search for radioprotective measures. Some antioxidant cocktails are considered as free radical scavengers, which ameliorate the effects of ionizing radiation. The antioxidant action of some vitamins including vitamins E, A and C beside selenium (selenium vit) can designate them as radio-protective agents. Fifty five male Swiss albino rats were divided into 4 groups, the first one served as control. Rats of the second group were exposed to 7 Gy of whole body gamma irradiation. Rats of the third group were subjected to daily oral administration of selenium vit (0.45 g/kg body weight) for 15 days. The fourth group of animals received the same dose of selenium vit followed by radiation exposure.The protective effect of selenium vit was monitored by studying the serum levels of sodium (Na), potassium (K), urea and creatinine.The results showed that whole body gamma irradiation of rats at 7 Gy (single dose) induced significant elevations in the levels of K, urea and creatinine after 3 and 10 days post-irradiation exposure. Conversely, the level of serum Na showed significant depletion. The histopathological results showed different distortion in the renal corpuscles and renal convoluted tubular epithelial cells. These distortions varied from swelling, vacillation to necrosis and complete degeneration of the epithelial cells of the proximal a of the epithelial cells of the proximal and distal tubules. The kidney glomeruli were shrunken and obvious lesions in the fine structure of the renal tissue were detected such as swelling and cristalysis of the mitochondria. The rough endoplasmic reticulum (RER) exhibited various degrees of damage dilatation, fragmentation, degranulation and destruction. Lysosomes were abundant and destruction of the brush border was evident. The nuclei showed irregular nuclear membrane besides clumped marginal chromatin

Effects of lithium chloride on testicular steroidogenic and gametogenic functions in mature male albino rats  

International Nuclear Information System (INIS)

The present study was undertaken to evaluate the effects of lithium, on steroidogenic and gametogenic functions of testis in the rat. Adult male rats of Wistar strain were injected with lithium chloride at the dose of 0.1 mg, 0.2 mg, and 0.4 mg/100 g body weight/day for 21 days. All the treated animals along with the vehicle treated controls were sacrificed 24 hours after the last injections. Testicular steroidogenic activity was evaluated by measuring the activities of two steroidogenic key enzymes, ?5-3? hydroxysteriod dehydrogenase (?5 -3?-HSD) and 17? hydroxysteroid dehydrogenase (17? -HSD). Gametogenic capacity was determined by counting the number of germ cells at stage VII of seminiferous cycle. Plasma levels of follicle stimulating hormone (FSH), luteinizing hormone (LH), prolactin (PRL) and testosterone (T) were measured by radioimmunoassay (RIA). Administration of lithium chloride at a dose of 0.1 mg/100g body wt. for 21 days led to insignificant changes of plasma FSH, LH, PRL and T along with unaltered activities of testicular ?5 -3?-HSD, 17 ?-HSD activities and gametogenesis

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

Cognitive effects of acute restraint stress in male albino rats and the impact of pretreatment with quetiapine versus ghrelin.  

Science.gov (United States)

Stress is any condition that seriously affects the balance of the organism physiologically and psychologically. Stress activates the hypothalamic-pituitary-adrenal (HPA) releasing glucocorticoid hormones that produce generalized effects on different body systems including the nervous system. This study aimed to investigate the effect of acute restraint stress (ARS) on cognitive performance by measuring spatial working memory in Y-maze, behavior (anxiety and exploratory behavior) in open field test, expression of synaptophysin and glial fibrillary acidic protein (GFAP) in the hippocampus by immunohistochemistry, dopaminergic receptors (D2) in the basal ganglia by gene expression and comparing the effect of ghrelin and quetiapine on the previous parameters. 36 adult male albino rats constituted the animal model of this work and have been divided into six groups: control group, control group exposed to ARS, quetiapine group, quetiapine group exposed to ARS, ghrelin group and ghrelin group exposed to ARS. We demonstrated more neuroprotective effect for quetiapine compared to ghrelin on stress response, anxiety behavior and working spatial memory impairment due to ARS. PMID:25391717

The Histological Effect of Hunger Stress on the Stomach in Male Albino Rats: A Study of Light Microscope  

Directory of Open Access Journals (Sweden)

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.

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

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

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

The 3rd group (protective group, the rats were injected (i.p. with LA (100 mg/kg b·w/day for 7 days after treatment with GSE (100 mg/kg b·w/day for 3 weeks. The 4th, 5th and 6th groups (therapeutics groups, rats were injected (i.p. with subacut dose (100 mg/kg b·w/day of lead acetate for 7 days, then treated with GSE (100 mg/kg b·w/day for one, two and three weeks, respectively. The level of norepinephrine (NE, dopamine (DA, serotonin (5-HT and 5-hydroxyindol acetic acid (5-HIAA were evaluated in brain regions (cerebellum, brainstem, striatum, cerebral cortex, hypothalamus and hippocampus. The result indicated that the administration of subacute dose of LA (100 mg/kg/day, i.p. induce a significant decrease in NE, DA, 5-HT and 5-HIAA content in all tested brain regions. Also the obtained data showed significant increase in liver enzymes: serum glutamate oxaloacetate transaminase (GOT, serum glutamate pyruvate transaminase (GPT and Lactate dehydrogenase (LDH level in group 2 (positive control. There is an improvement in neurotransmitters content. Also the obtained data showed significant in- crease in liver enzymes of protective (G3 and therapeutics groups (G4, G5 and G6 which received GSE compared with animal group that received lead acetate (G2. This is may be the presence of proanthocyanidins and procyanidins which have antioxidant and free radical scavenging activities. The result suggests that grape seed extract may prevent lead-induced neurotoxicity and hepatotoxicity.

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 administratiould be concluded that garlic administration may has a beneficial role in restoring the biochemical disorders induced by 5 Gy gamma irradiation

The disposition and metabolism of 1,3,5-[U-14C]trioxane in male Wistar albino rats  

International Nuclear Information System (INIS)

The present study was designed to investigate 1,3,5-[U-14C]trioxane (TOX) distribution, excretion and metabolism. The experiments were performed on male Wistar albino rats after a single administration of TOX at doses of 40 mg/kg and 400 mg/kg. The exhaled air proved to be the main route of 14C elimination, mainly as 14CO2. During the first 12 h following the administration of 40 mg/kg of TOX the exhalation of 14CO2 was monophasic, with a half-life of 3.5 h. After the administration of 400 mg/kg, TOX was eliminated mainly as 14CO2 with the exhaled air (77%) and unchanged TOX (8%). About 3% of 14C was excreted in the urine as unchanged 1,3,5-trioxane. With regards to TOX elimination from blood plasma for the lower dose, a biphasic process was observed, with half-lives of 4.5 and 72 h. The amount of 14C bound by the erythrocytes was minute compared with the amount in blood plasma. When the higher dose of TOX was administered the efficiency of 14C binding to the erythrocytes was found to be 10 times higher than the respective value for blood plasma. Among the examined tissues the highest concentration of TOX-derived radioactivity was detected in the liver while the lowest was in fat tissue and brain. A subsequent decay of radioactivity occurred in the tissues. The results of the present study indicate that TOX belongs to the group of compounds, which abelongs to the group of compounds, which are rapidly eliminated from the organism; hence TOX should not be expected to accumulate within the tissues. The data obtained confirm the assumed pattern of metabolic transformation, according to which 1,3,5-trioxane undergoes enzymatic transformation to formaldehyde, with carbon dioxide and water being the final products.

Chronic effect of olive oil on some neurotransmitter contents in different brain regions and physiological, histological structure of liver and kidney of male albino rats  

Directory of Open Access Journals (Sweden)

Full Text Available Olive oil is an important source of mono-unsaturated fat and a prime component of the Mediterranean diet. The beneficial health effects of olive oil are due to both its high content of mono-unsaturated fatty acids and its high content of anti-oxidative substances. The objective of this study was to investigate the basis for the epidemiological information relating to the health benefits associated with the consumption of ex-tra-virgin olive oil (EVOO. The effect of olive oil on norepinephrine (NE, dopamine (DA, serotonin (5-HT and gamm-aminobutyric acid (GABA con-tents in different brain regions and histological structure of liver and kindey of male albino rats was studied. The chronic administration of olive oil (7.5 mg/kg body wt. caused a significant increase in norepinephrine (NE, dopamine (DA , serotonin (5-HT and gamm-aminobutyric acid (GABA con-tent in different brain regions (Cerebellum, striatum, cerebral cortex, hypothalamus, brain steam and hip-pocampus of male albino rats. The increase in NE, DA, 5-HT, and GABA content in the different CNS areas of male albino rat may be due to the inhibition of Ca2+/calmodulin binding which plays an important role in the release of these neurotransmitters. The results, also, revealed that urea and creatinne con-centrations in rats with oral administration with olive oil were decreased. Meanwhile, the activities of the enzymes AsT, AlT and ALP were elevated. The pre-sent results indicated that there is no change in tis-sues of kidney after treated with virgin olive oil. Olive oil may potentially be safe for use as a sedative drug. improvement also led to the reductions in risk of Alzheimer’s and Parkinson’s diseases.

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-signiftively. 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

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

Beneficial use of continuous administration of crataegus oxycantha in irradiated male albino rats  

International Nuclear Information System (INIS)

Exposure to ionizing radiation has become frequent with its vast applications in diagnosis, treatment and industry rather than possible environmental pollution with radiation. The animals of this study were allocated into three groups, control group, irradiated group (5 Gy one shot) and hawthorn treated post-irradiation group. Exposure to radiation was implicated with hematological suppression in all hematological parameters tested red blood cells count (RBCs), hemoglobin content (Hb), hematocrit percentage (HCT) and white blood cells count (WBCs). Radiation exposure caused alteration of lipid metabolism leading to increased total lipids, triglycerides, total cholesterol, and low density lipoprotein (LDL) and decreased high density lipoprotein (HDL). In addition, liver enzymes were also elevated, while serum albumin was diminished referring to liver dysfunction. The male reproductive hormone (testosterone) was severely inhibited along with glutathione. Administration of extraction of Crategous oxinatha (hawthorn) with a dose of 500 g/kg b.w. orally for consecutive 15 days post-irradiation showed significant ameliorating effects on both hematological and biochemical parameters leading to the suggestion of using hawthorn as food additive in relatively high amount

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 haived 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

Effect of Ginkgo Biloba Extract on The Toxicity and Distribution of 14C-Carbon Tetrachloride in Adult Male Albino Rats  

International Nuclear Information System (INIS)

The present study was conducted to investigate the possibility of whether the standardized extract of Ginkgo biloba (EGb-761) has a protective and therapeutic effect on the toxicity and distribution of 14C-CCl4 in different brain areas (cerebellum, striatum, cerebral cortex) of adult male albino rats for determination of distribution of 14C-CCl4 and monoamine contents (dopamine (DA), norepinephrine (NE) and serotonin (5- HT)) and also estimation of serum total antioxidant capacity (TAC) in adult male albino rat. The i.p. injection of 14C-CCl4 (1ml/kg) resulted in increase in the activity of counted 14C in all tested brain areas all over the experimental period. The treatment with EGb-761 (200 mg/kg) pre and post 1'4C-CCl4 injection resulted in a significant reduction (P14C in tested areas. The maximum reduction was observed in cerebral cortex on 1st day (-40.91%) after pre-treatment with EGb-761. The treatment with CCl4 (1ml/kg) resulted in a significant reduction (P4 . The pre and post-treatment with EGb-761 ameliorated the effect of CCl4 in all tested brain areas throughout the experimental period. This may be due to the free radical scavenger property of its constituents. Data obtained could recommend that EGb-761 has a protective and therapeutic effect against toxicity produced by CCl4 .

Physiological and Biochemical Alterations Induced by Subchronic Administration of Deltamethrin can be Possibly Corrected by Zinc Supplementation in Male Albino Rat  

Directory of Open Access Journals (Sweden)

Full Text Available The present study was conducted aiming to evaluate the possible effect of zinc supplementation as potent antioxidant in counteracting some of the physiological and biochemical alterations induced by subchronic administration of deltamethrin, a synthetic pyrethroid. Deltamethrin (DM was injected in two doses in male albino rats in presence or absence of zinc. Many physiological and biochemical alteration have been induced by deltamethrin intoxication. Zinc supplementation proved a considerable ability to overcome some but not all of these alterations. The present investigation has also proved the possibility of using the isozyme electrophoretic patterns in testing for xenobiotic intoxication. The rate of gene expression of ALP2 and ALP3 isozymes, but not of ALP1 are stimulated by DM intoxication. In case of ALP3 the rate of gene expression seemed to be dose-dependent.

Full Text Available Different metabolic disorders including hypertension cause renal damage. The aim of this study was to study the effect of Thymus Vulgaris (TV on kidneys of induced hypertensive rats through biochemical and ultrastructure examination. Thirty three adult male albino rats were divided into 3 groups 11 animals each (control, untreated and treated. The first (control group was fed and followed up for 8 weeks by measuring the systolic BP. In the second group, hypertension was induced by ligation of left renal artery to have systolic BP >150 mmHg and was followed up till the end of study. The third group in which hypertension was induced were given TV as 100 mg/kg body weight daily. The surviving 11 rats per each group were weighed again and killed with an overdose of phenobarbital and blood was collected to measure the blood chemistry. Following laparotomy, right kidney was dissected and excised from each rat and divided into 2 parts: one part was immersed in 10% formal saline and prepared for light microscopic examination. The other parts was immersed into 2.5 % glutaraldehyde and prepared for electron microscopic examination using transmission microscopy in faculty of medicine Zagazig university Egypt. A Significant increased was noticed in creatinine and cholesterol in untreated in contrast to control and treated hypertensive rats. There was significant reduction of Blood Pressure (BP on using TV in contrast to untreated group. In untreated hypertensive group some cortical fields showed scars surrounding obsolete shrinkage glomeruli with inflammatory infiltrates with reciprocal dilatation of their Bowman's capsules. Ultrastructure examination showed thick glomerular endothelium with obliterated endothelial fenestrations. In treated hypertensive group the rat kidneys showed preserved cortical appearance and normal trilaminar structure but with focal thickening. Induced hypertension in rats affected renal tissues with biochemical alterations which all can be improved and/or prevented by using Thymus vulgaris herbal extract.

Bioefficacy of hydromethanolic extract of tuber of Chlorophytum borivilianum (Safed Musli) for the management of male infertility in cyproterone acetate-treated albino rats.  

Science.gov (United States)

Increase in male sexual dysfunction, and its treatment with conventional aphrodisiac drugs with side effects lead to investigate the spermatogenesis and androgenesis augmentative efficacy of hydromethanolic (40 : 60) extract of root of Chlorophytum borivilianum (family - Liliaceae) against cyproterone acetate-induced subfertility in Wistar strain male albino rat. For this purpose, experimental rats were divided into three treatment groups: vehicle (received distilled water), cyproterone acetate (gastric intubation at 250 mg kg(-1) twice daily for 35 days) and cyproterone acetate plus root extract of C. borivilianum (gastric intubation at 250 mg kg(-1) plus 400 mg kg(-1) with an interval of 20 min twice daily for 35 days). After 35-day treatment, all rats were euthanised. Reproductive deviations towards negative side were investigated by screening the spermatogenic and steroidogenic biosensors. Oxidative stress profile in reproductive organs and sperm pellet was evaluated by biochemical assessment of antioxidative enzyme activities and level of end products of the lipid peroxidation. Apoptosis profile was evaluated by Western blot study, TUNEL assay and DNA fragmentation study of testicular tissues. Evaluation of toxicity profile was included for experimental investigation. After cyproterone acetate treatment, the pituitary-testicular axis was deviated towards the negative side and its tuning system was affected by oxidative stress and apoptosis-mediated process, which reduced the quality of semen and finally led to subfertility. Co-administration of C. borivilianum root extract enhanced male reproductive potentiality and prevented the negative deviations after the treatment with cyproterone acetate by means of increasing oxidative defence and maintaining homeostasis in testicular apoptosis process.

The immunological and histopathological changes of Tramadol, Tramadol/Acetaminophen and Acetaminophen in male Albino rats "Comparative study"  

Directory of Open Access Journals (Sweden)

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.

Evaluation of the protective role of vitamin C in imidacloprid-induced hepatotoxicity in male Albino rats  

Science.gov (United States)

In the present study, the effects of oral administration of imidacloprid for 4 weeks on serum biochemical, oxidative stress, histopathological and ultrastructural alterations were assessed in the liver of male rats. This study also aimed to investigate whether vitamin C could protect against the imidacloprid-induced oxidative stress. Forty-eight male Sprague dawley rats were divided into four groups of 12 animals each. Group 1 served as the control, while groups 2 and 4 were administered with imidacloprid (80 mg/kg body weight) daily by oral gavage for 28 days. In addition to imidacloprid, group 4 also received vitamin C at 10 mg/kg daily by oral gavage for 28 days. Group 3 was maintained as the vitamin C control (dose as above). The serum biochemical assays revealed a significant (P < 0.05) increase in alanine transaminase and aspartate transaminase and decrease in total protein in group 2. The tissue biochemical profile revealed a significant (P < 0.05) reduction in reduced glutathione concentration in the liver of group 2 animals. Histologically, the liver showed marked dilation, congestion of central vein, portal vein and sinusoidal spaces, vacuolation/fatty change and degenerated hepatocytes. Ultra thin sections of the liver revealed swollen nuclei, varied size and shape of mitochondria, disrupted chromatin and rough endoplasmic reticulum. Co-treatment with vitamin C significantly (P < 0.05) reversed the imidacloprid-induced changes. PMID:23633837

Nano gold conjugation, anti-arthritic potential and toxicity studies of snake Naja kaouthia (Lesson, 1831) venom protein toxin NKCT1 in male albino rats and mice.  

Science.gov (United States)

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

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 amelit 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.

The melatonin treated group showed significant decrease in urea level with highly significant decrease in creatinine, T3 and T4 hormones. The testosterone treated group showed highly significant increase in urea, T3 and T4 hormones and highly significant decrease in creatinine level. Whereas, fifth group showed significant decrease in urea accompanied with a highly significant decrease in creatinine and highly significant increase in T3 with a significant increase in T4. The histological changes induced by aging and anti-aging hormones included intertubular haemorrhage, odematous areas present between the seminiferous tubules. The interstitial tissue was degenerated. The degenerated seminiferous tubules revealed maturation arrest in late-stage spermatides. Conclusion In conclusion, aging and anti-aging hormones administration into adult male rats exerts a clear effect on the kidney and the thyroid functions and on the testicular structure. On the other hand, amelioration in T3 &T4 serum level was found in anti-aging treated rats compared with untreated aged rats.

The effect of bisphenol A on some oxidative stress parameters and acetylcholinesterase activity in the heart of male albino rats.  

Science.gov (United States)

Bisphenol A (BPA) is an endocrine disrupting chemical used on a wide range in industry. Several studies reported that BPA may cause cardiovascular disorders in humans and animals. The present study aims to investigate the effect of BPA on the heart of adult male rats. The rats received a daily oral administration of BPA (25 mg/kg for 6 weeks and 10 mg/kg for 6 and 10 weeks). It was found that BPA at the two studied doses induced a significant increase in malondialdehyde, and a significant decrease in catalase after 6 weeks. Moreover, a significant decrease in reduced glutathione and acetylcholinesterase (AchE) activity was observed after treatment with the two doses of BPA throughout the studied time intervals. The two doses (25 and 10 mg/kg) resulted in a significant decrease in nitric oxide (NO) levels after 6 and 10 weeks, respectively. A significant increase in body weight gain occurred in all animals after BPA treatment. These results suggest that BPA has cardiotoxic effects which are mediated by the oxidative stress resulting from the overproduction of free radicals, the deficiency of NO and the inhibition of AchE leading to cholinergic activation. The obesity promoting effect of BPA may also participate in the observed cardiovascular disturbances. PMID:24337652

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.

Phenolic Profiling and Evaluation of Contraceptive Effect of the Ethanolic Extract of Salsola imbricata Forssk. in Male Albino Rats  

Science.gov (United States)

Reported researches dealing with either composition or bioactivity of Salsola imbricata are limited. This study was conducted aiming to investigate the phenolic composition of the plant and evaluate its efficacy as male contraceptive. Polyphenols, namely, phenolic acids and flavonoids, were qualitatively and quantitatively analysed by RP-HPLC in the hydrolysed methanol extract using two different wavelengths, 280 and 330?nm. The efficiency of different solvents in extracting the plant phenolics was assessed via spectrophotometric determination of the total phenolic and flavonoid contents. Acute toxicity study was carried out on the ethanolic extract to ascertain its safety prior to biological evaluation. The contraceptive effect was assessed, in male rats, by oral administration of the extract at two doses (250 and 500?mg/kg b. wt.), over a period of 65 days. HPLC analyses allowed the identification and quantification of a total of 13 and 8 components in the hydrolysed-methanol extract; the overall phenolic composition was dominated by quercitrin (12.692%) followed by coumaric acid (4.251%). Prolonged oral administration of the ethanolic extract caused slight reduction in the testis weight only. A significant decrease in the sperm count was observed (P < 0.01) in the two treated groups while significant decrease in the epididymal sperm motility was only observed in the high dose group. Morphological abnormalities were observed in sperms of treated animals. No distinct change in serum FSH, LH, and testosterone concentration was recorded. The histopathological findings supported to a high extent these results. The male contraceptive activity of Salsola imbricata could be ascribed to its phenolic components, especially quercitrin.

Carbamate Toxicity and Protective effect of vit. A and vit. E on some biochemicalaspects of male albino rats  

Directory of Open Access Journals (Sweden)

Full Text Available The effect of daily oral administration of carbamate (1/10 L.D50 on rats for 30 successive days were studied. The male rats were divided into five groups (control, control + oil, carbamate, carbamate + vit. A and carbamate + vit. E. Each group (except control and control + oil was daily administrated carbamate (0.012 mg/kg B.wt.. Two groups of carbamate ­ intoxicated animals provided with vit. A (700 mg/kg.B.wt or vit. E (10 mg/kg.B.wt. Poisoning symptoms were recorded, e.g. unbalanse, diarrhea, have poor health and posterior limbs rigidity. Haematological parameters showed a significant decrease in red blood corpuscles (R.B.Cs, white blood corpuscles (W.B.Cs count, Haemoglobin concentration and haematocrit value in groups treated with carbamate, and an improvement in these values was observed in groups treated with the anti-oxidants (vit. A and vit. E. Total lipids cholesterol, total proteins, albumin, glucose, LDH, AST, ALT, adrenaline and noradrenaline were measured in serum. Total proteins, total lipids, of tissues (liver, heart, muscle and kidney were investigated. The present study declare that, carbamate induced a significant elevetion in serum LDH, glucose. total lipids,cholesterol, AST, ALT, adrenaline and noradrenaline. On the other hand, causes a significant reduction in total proteins and albumin. The total lipids and total proteins of the tissue were recorded highly significant decrease in the group treated with carbamate only. From another point of view, antioxidant ameliorated the effect of carbamate on tissues. So, it is clear that administration of vit. E or vit. A. reduced the effect of carbamate on biochemical alteration to various extent. The antioxidant property of vitamin A and vitamin E seem to be responsible for the observed protection against carbamate intoxication.

International Nuclear Information System (INIS)

The present study was conducted to investigate the protective and therapeutic effect of the standardized extract of Ginkgo biloba (EGb-761) on distribution of14C-CCl4 in different brain areas (hippocampus, brain stem and hypothalamus) and its toxicity using the determination of monoamine contents (dopamine (DA), norepinephrine (NE) and serotonin (5-HT)) as well as estimation of serum nitric oxide (NO) and malondialdehyde (MDA) in adult male albino rat. The i.p. injection of14C-CCl4 (1 ml/kg) resulted in increase in the activity of 14C amount in all tested brain areas during experimental period. The treatment with EGb-761 (200 mg/kg) pre and post 14C-CCl4 treatment resulted in a significant reduction (P14C amount in areas under investigation. The maximum reduction was recorded in hypothalamus on 3rd day (-49.28%) after pre-treatment with EGb-761. The treatment with CCl4 (1ml/kg) resulted in a significant reduction (P4. The pre and post-treatment with EGb-761 ameliorated the effect of CCl4 in all tested brain areas throughout the experimental period, which might be due to the free radical scavenger property of its constituents. The datager property of its constituents. The data obtained could recommend that EGb-761 has a protective and therapeutic effect against toxicity produced by CCl4.

An experimental study on effect of antioxidant vitamin E in stress and alcohol induced changes in male fertility in albino rats.  

Directory of Open Access Journals (Sweden)

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.

Neuroprotective Evaluation of Extract of Ginger (Zingiber officinale Root in Monosodium Glutamate-Induced Toxicity in Defferent Brain Areas Male Albino Rats  

Directory of Open Access Journals (Sweden)

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.

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 hrecorded.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.

Possible protective and curative role of thiamine pyrophosphate against radiation induced biochemical and histological changes in male albino rats  

International Nuclear Information System (INIS)

The present study has been performed to investigate the possible curative and protective role of thiamine pyrophosphate (TPP) in minimizing the radiation-induced changes in certain biochemical and histological parameters in the liver and kidney of rats. The activity of liver alanine aminotransferase (ALT), aspartate aminotransferase (AST) and g-glutamyl transferase (g-GT) as well as kidney creatinine and urea concentrations were measured. In addition, histological changes in the liver and kidney tissues were examined.The results obtained revealed that whole body g-irradiation of rats at 5 Gy (single dose) induced significant increase in the activity of liver g-GT, ALT and AST and also significant increase in the concentration of creatinine and urea in the kidney at 1, 2, 3, and 4 weeks post-irradiation. Exposure to radiation induced also distortion in the architecture pattern of the liver as well as degenerative changes of the proximal convoluted tubules of the kidney.The intraperitoneal administration of TPP at a concentration of 2mg/Kg body weight to unirradiated rats for 5 consecutive days did not induce any significant changes in biochemical and histological parameters studied at all the experimental periods. TPP given to rats for 5 consecutive days either before or after irradiation ameliorated the intensity of changes induced due to radiation exposure. Accordingly, it was concluded that TPP could exert a beneficial protective and curative role against some radiactive and curative role against some radiation-induced biochemical and histological disorders in liver and kidney. Extrapolation of the results obtained in the present study to patients who need such treatments and undergoing radiotherapy requires further investigations

The Interaction Between Angiotensin Converting Enzyme Inhibitor (Captopril and Heat Stress in The Male Albino rats. 2-Tissue Analysis  

Directory of Open Access Journals (Sweden)

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.

The Possible Protective Role of Genistein against Some Biochemical Alterations Induced by ?-Irradiation in Male Albino Rats  

International Nuclear Information System (INIS)

Genistein is one of the main isoflavones, as an active compound of dietary antioxidants, has shown considerable promise as an effective agent against oxidative stress. The purpose of this study was to determine the radio-protective effect of genistein administration to rats at a non-toxic dose (200 mg/kg b.wt.) against Gamma-irradiation-induced oxidative stress. Gamma-irradiation (2.5 Gy x 3 delivered every other day) resulted in a significant decrease in hepatic glutathione contents (GSH), superoxides dismutase (SOD) and catalase (CAT) activity, insulin level as well as the concentration of high density lipoprotein cholesterol (HDL-C). Moreover, a remarkable increase in the malondialdehyde (MDA) concentration, the activity of some liver enzymes, the level of glucose and the concentrations of total cholesterol (TC), triglycerides (TG), low density and very low density lipoprotein-cholesterol was observed in ?-irradiated rats. In contrast, genistein administration prior to ?-irradiation of rats ameliorated ?-irradiation-induced oxidative stress by elevating the activity of antioxidant enzymes, enhancing liver function in addition to improving the lipid metabolism. From the results of this study it possible to conclude that genistein is a natural antioxidant and seems to be beneficial for correcting the biochemical alterations and preventing ?-irradiation complications

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 histolog 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.

Evaluation of silymarin and / or ginger effect on induced hepatotoxicity by carbon tetrachloride in male albino rats  

Directory of Open Access Journals (Sweden)

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.

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.

Histopathological effects of cisplatin, doxorubicin and 5-flurouracil (5-FU) on the liver of male albino rats.  

Science.gov (United States)

Cisplatin, doxorubicin and fluorouracil (5-FU), drugs belonging to different chemical classes, have been extensively used for chemotherapy of various cancers. Despite extensive investigations into their hepatotoxicity, there is very limited information on their effects on the structure and ultra-structure of liver cells in vivo. Here, we demonstrate for the first time, the effects of these three anticancer drugs on rat liver toxicity using both light and electron microscopy. Light microscopic observations revealed that higher doses of cisplatin and doxorubicin caused massive hepatotoxicity compared to 5-FU treatment, including dissolution of hepatic cords, focal inflammation and necrotic tissues. Interestingly, low doses also exhibited abnormal changes, including periportal fibrosis, degeneration of hepatic cords and increased apoptosis. These changes were confirmed at ultrastructural level, including vesiculated rough endoplasmic reticulum and atrophied mitochondria with ill-differentiated cisternae, dense collection of macrophages and lymphocytes as well as fibrocytes with collagenous fibrils manifesting early sign of fibrosis, especially in response to cisplatin and doxorubicin -treatment. Our results provide in vivo evidence, at ultrastructural level, of direct hepatotoxicity caused by cisplatin, doxorubicin and 5-FU at both light and electron microscopi. These results can guide the design of appropriate treatment regimen to reduce the hepatotoxic effects of these anticancer drugs. PMID:19584954

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. ed 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)

Science.gov (United States)

Natural products have long gained wide acceptance among the public and scientific community in the gastrointestinal ulcerative field. The present study explore the potential effects of aged garlic extract (AGE) on indomethacin-(IN-) induced gastric inflammation in male rats. Animals were divided into six groups (n = 8) control group, IN-induced gastric inflammation group via oral single dose (30?mg/kg to fasted rats) two AGE orally administered groups (100 and 200?mg/kg for 30 consecutive days) two AGE orally administered groups to rats pretreated with IN at the same aforementioned doses. The results declared the more potent effect of the higher AGE dose (200?mg/kg) as compared to that of the 100?mg/kg dose in the gastroprotective effects reflected by significant gastric mucosal healing of damage and reduction in the total microbial induced due to indomethacin administration. In addition to the significant effect to normalize the significant increase in malondialdehyde (MDA), myeloperoxidase (MPO), tumor necrosis factor-? (TNF-?) values, and the significant decrease in the total glutathione (tGSH), superoxide dismutase (SOD), and catalase (CAT) values induced by indomethacin. The results support AGE antioxidant, anti-inflammatory, and antimicrobial potency reflected by the healing of the gastric tissue damage induced by indomethacin. PMID:24876878

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

Origins of Albino and Hooded Rats: Implications from Molecular Genetic Analysis across Modern Laboratory Rat Strains  

Science.gov (United States)

Albino and hooded (or piebald) rats are one of the most frequently used laboratory animals for the past 150 years. Despite this fact, the origin of the albino mutation as well as the genetic basis of the hooded phenotype remained unclear. Recently, the albino mutation has been identified as the Arg299His missense mutation in the Tyrosinase gene and the hooded (H) locus has been mapped to the ?460-kb region in which only the Kit gene exists. Here, we surveyed 172 laboratory rat strains for the albino mutation and the hooded (h) mutation that we identified by positional cloning approach to investigate possible genetic roots and relationships of albino and hooded rats. All of 117 existing laboratory albino rats shared the same albino missense mutation, indicating they had only one single ancestor. Genetic fine mapping followed by de novo sequencing of BAC inserts covering the H locus revealed that an endogenous retrovirus (ERV) element was inserted into the first intron of the Kit gene where the hooded allele maps. A solitary long terminal repeat (LTR) was found at the same position to the ERV insertion in another allele of the H locus, which causes the so called Irish (hi) phenotype. The ERV and the solitary LTR insertions were completely associated with the hooded and Irish coat patterns, respectively, across all colored rat strains examined. Interestingly, all 117 albino rat strains shared the ERV insertion without any exception, which strongly suggests that the albino mutation had originally occurred in hooded rats. PMID:22916206

Effect of a Long Term Consumption of a Diet Supplemented with Leaves of Gongronema latifolium Benth. on Some Biochemical and Histological Parameters in Male Albino Rats  

Directory of Open Access Journals (Sweden)

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.

QUANTITATIVE AND HISTOCHEMICAL STUDY ON THE ADRENAL MEDULLA IN POST NATAL PERIOD OF ALBINO RAT  

Directory of Open Access Journals (Sweden)

Full Text Available Background: The present work was based on the evaluation of histological, histochemical, and quantitative study on the adrenal medulla of the white albino rat in the different post natal age period. Material and methods:Sixty male albino rats were used in this study. The rats were classified to 4 main groups as follows: - Group one : One week old albino rats. - Group two: One month old albino rats. - Group three: Three months old albino rats. - Group four: Senile rats. Three main parameters were performed in this study, the first was the study of the morphological changes in the adrenal medulla in the different postnatal age groups. The second was concerned with the histochemical studies while the last parameter was the quantitative studies on the gland volume as well as its cellular count. These three parameters were performed by using different staining techniques. Results: The results showed that medullary cells in the early age groups were arranged in non-differentiated groups and become more differentiated in the older age groups. Both reticular and elastic fibers in the older age groups showed a definite increase especially at the region of corticomedullary zone. The different types of chromaffin cells were more observed at the old age groups. The concentration of ascorbic acid granules was more marked in the senile group. The quantitative changes were in the form of increased medullary volume especially in the old age. The number of chromaffin cells as well as the concentration of ascorbic acid contents was more noticed in the old age group. Conclusions: The differentiation of both divisions of the adrenal gland was not noticed in the early age groups. Cellular and fibrous differentiations were more seen in older age groups which may reflects an idea about the degree of gland maturation

Comparative Effects of Some Medicinal Plants: Anacardium occidentale, Eucalyptus globulus, Psidium guajava, and Xylopia aethiopica Extracts in Alloxan-Induced Diabetic Male Wistar Albino Rats.  

Science.gov (United States)

Insulin therapy and oral antidiabetic agents/drugs used in the treatment of diabetes mellitus have not sufficiently proven to control hyperlipidemia, which is commonly associated with the diabetes mellitus. 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

Chronic alcoholism-mediated metabolic disorders in albino rat testes  

Directory of Open Access Journals (Sweden)

Full Text Available There is good evidence for impairment of spermatogenesis and reductions in sperm counts and testosterone levels in chronic alcoholics. The mechanisms for these effects have not yet been studied in detail. The consequences of chronic alcohol consumption on the structure and/or metabolism of testis cell macromolecules require to be intensively investigated. The present work reports the effects of chronic alcoholism on contents of free amino acids, levels of cytochrome P450 3A2 (CYP3A2 mRNA expression and DNA fragmentation, as well as on contents of different cholesterol fractions and protein thiol groups in rat testes. Wistar albino male rats were divided into two groups: I - control (intact animals, II - chronic alcoholism (15% ethanol self-administration during 150 days. Following 150 days of alcohol consumption, testicular free amino acid content was found to be significantly changed as compared with control. The most profound changes were registered for contents of lysine (-53% and methionine (+133%. The intensity of DNA fragmentation in alcohol-treated rat testes was considerably increased, on the contrary CYP3A2 mRNA expression in testis cells was inhibited, testicular contents of total and etherified cholesterol increased by 25% and 45% respectively, and protein SH-groups decreased by 13%. Multidirectional changes of the activities of testicular dehydrogenases were detected. We thus obtained complex assessment of chronic alcoholism effects in male gonads, affecting especially amino acid, protein, ATP and NADPH metabolism. Our results demonstrated profound changes in testes on the level of proteome and genome. We suggest that the revealed metabolic disorders can have negative implication on cellular regulation of spermatogenesis under long-term ethanol exposure.

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

Chemical Composition, Antimicrobial Activity of Propolis Ethanolic Extract and Its Improving Role of Biochemical Changes Induced by Carbon tetrachloride in Male Albino Rats  

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 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

Ribavirin exposure induces histopathological changes in the seminiferous tubules of testes in albino rats  

International Nuclear Information System (INIS)

Study objectives: The objectives of the study are to describe and compare histopathological changes in the seminiferous tubules of testes of rat, with different doses of Ribavirin at different time intervals. Introduction: The chemical disturbances may affect a vast number of potential sites in male reproductive system as well as its complex hormonal regulation. Testicular toxicity may reduce the fertility of the male. The current study was conducted to evaluate the effects of Ribavirin on the histological structure of seminiferous tubules in the testes of albino rats. Materials and Methods: Seventy two sexually mature adult male albino rats weighing 180-200gms were divided into four groups: A, B, C and D; each group having 18 rats. Ribavirin was administered intraperitoneally in different doses to these groups that were 20mg, 100mg and 200mg/kg body weight, while group A was control. Each group was further divided into three subgroups according to three time points which were selected for sacrifice that were 20th, 40th and 60th day from the last exposure to drug. Six randomly selected rats from each group were sacrificed on every sacrifice time. Results and Conclusion: The seminiferous tubules with degenerative changes like appearance of vacuole and necrotic material were observed in comparison to control groups, on 20th day of sacrifice in all groups. In rats sacrificed on day 40th and 60th, the sign of recovery in the form of regeneration of seminiferous epithelium was observed that was more marked in low dose groups than high dose groups which showed late recovery. We conclude that ribavirin being used as antiviral drug induces reversible degenerative changes in the seminiferous tubules of testes of albino rats. (author)

The disposition of [2,3-14C]-methyl and [2,3-14C]-2-ethylhexyl acrylate in male wistar albino rats  

International Nuclear Information System (INIS)

The disposition of methyl [2,3-14C]-acrylate (MA) and 2-ethylhexyl [2,3-14C]-acrylate (EHA) following intraperitoneal and oral administration to rats has been studied. The 14C found in the tissues was mainly associated with liver, kidneys and lungs. Loss of 14C from these tissues occurred fairly rapidly, excluding the rats given EHA intraperitoneally. Most of the administered acrylated underwent rapid metabolism and excretion with expired air (more than 50% of the dose and urine (10-50% of the dose). Significant differences in the rates of 14C loss from tissues and excretion occurred after intrapritoneal administration of MA and EHA. A possible cumulation of EHA in the organism was suggested.

Radiological and physiological studies on the role of some therapeutic agents used for internal decontamination of radionuclides from male albino rats  

International Nuclear Information System (INIS)

With the earths increasing nuclear arsenal and the growing use of nuclear energy, the possibility of radiological accidents involving release of radioactive materials, internal contamination may consequently occurs via inhalation, ingestion or absorption of radioisotopes.Therefore, the present work was oriented to deal with four topics related to the internal decontamination of two of the most widely used isotopes, namely 134Cs and 60Co from contaminated rats:-In vitro study aimed to select agents that can strongly bind the two metal ions and elucidate the best conditions and the factors affecting this binding. The tested agents were bentonite, vermiculite and Prussian blue (PB). The sorption capacity of PB and vermiculite for both metal ions was high and equivalent to more than 1011 Bq 137Cs or 60Co per gram sorbent. As bentonite has lower capacity to both isotopes, further in vivo experiments were performed with PB and vermiculite.-In vivo studies, via 5 groups of rats, devoted to investigate the kinetics of excretion of 134Cs and/or 60Co from contaminated rats. The biological half lives of excretion, excretion stages for both isotopes and the effect of route of entry on the excretion were estimated.-In vivo studies aimed to investigate the effectiveness of PB + vermiculite and CaDTPA as therapeutic agents for accelerating the elimination of 134Cs and/or 60Co from cont4Cs and/or 60Co from contaminated rats. The study was performed via 6 groups of rats given different regimes of therapy. The results showed the high efficiency of PB + vermiculite for accelerating elimination of 134Cs and orally administrated 60Co while CaDTPA succeeded in accelerating intraperitoneally administrated 60Co. The study proved that oral administration of PB + vermiculite and injection with CaDTPA at the same time is very effective in accelerating elimination of both contaminants simultaneously.-The physiological studies aimed to evaluate the hazardous effects of 134Cs and/or 60Co incorporation and any side effect of therapeutic agents on hematological and biochemical parameters. The data obtained revealed that internal contamination causes a significant decrease in the RBC's counts, Hb concentration, haematocrit value, serum total proteins, albumin, serum inorganic phosphorous, in addition to a significant increase in serum urea, creatinine concentration, glucose, CPK and LDH activities. However, no significant changes were recorded in globulin, A/G ratio, total bilirubin, ALT, AST enzymatic activities, sodium, potassium and calcium levels. The treatment by the tested therapeutic agents has no significant effect on the same parameters and causes significant amelioration in the changes produced by internal contamination with variable degrees.

Ultrastructural Identification of the Basal-Granulated Cells in the Duodenum of Albino Rat  

Directory of Open Access Journals (Sweden)

Full Text Available The fine structure of the crypt epithelium of the duodenal mucosa in albino rats was studied to represent the types and distribution of the basal-granulated or endocrine cells. Twenty male animals were used. Perfusion-fixation was made and samples of duodenal mucosa were taken and processed to prepare epon-embedded specimens for examination by a transmission electron microscope. Cells containing membrane-bound granules were seen in the crypt epithelium. They were identified to be basal-granulated cells. Six different types of such cells were demonstrated. All of the cells were of the closed type. The possible functional significance of these closed cell types was discussed. Correlation among the distributions of such cells in the intestine of albino rat might enable the physiologists, internists and other research workers to study several biologically active peptides with well-established functions other than those which have long been investigated.

Effect of nigella sativa seeds extract on serum c-reactive protein in albino rats  

International Nuclear Information System (INIS)

C-reactive protein (CRP) is an acute phase protein. It predicts future risk of cardiovascular diseases. Different medicinal plants and their active ingredients possess the ability to reduce serum CRP levels and hence inflammatory disorders and cardiovascular diseases. In our study, ethanolic extract of Nigella sativa seeds was evaluated in albino rats for its possible effect on serum CRP levels. Objective: The objective of this study was to determine the effect of ethanolic extract of Nigella sativa seeds on an acute inflammatory biomarker/mediator, C-reactive protein (CRP) in albino rats. Study Design: Randomized controlled trial (RCT). Place and Duration of Study: Physiology Department, Services Institute of Medical Sciences (SIMS), Lahore; from September to November, 2009. Subjects and Methods: The study was carried out on 90 male albino rats. Five percent (5%) formalin in a dose of 50 meu1 was injected into sub-plantar surface of right hind paw of each rat to produce inflammation. The rats were randomly divided into three groups of thirty each. Group A was given normal saline (control); group B was given Nigella sativa seed extract; and group C received diclofenac sodium, as a reference drug. CRP levels in each group were measured from blood samples taken 25 hours after giving formalin. Results: The ethanolic extract of Nigella sativa seeds, given intraperitoneally, caused highly significant (p<0.001) reduction in serum CRP levels as compared to control group. The reduction in CRP levels by ethanolic extract of Nigella sativa was also significantly (p<0.05) more than that produced by diclofenac sodium. Conclusion: Our results suggest that Nigella sativa possesses ability to reduce serum CRP levels significantly, after production of artificial inflammation, in albino rats. (author)

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.

Attenuating Role of Vitamin C on Sperm Toxicity Induced by Monosodium Glutamate in Albino Rats  

Directory of Open Access Journals (Sweden)

Full Text Available The toxicity of monosodium glutamate has been on the increase due to increased patronage of fast foods; with its attendant effects. There have also been attempts to attenuate these effects. Hence, the attenuating role of vitamin C on sperm toxicity induced by monosodium glutamate was accessed on the weight of testes and epididymes, epididymal count, motility, viability, semen pH and sperm head abnormality in albino rat as a model. The male rats were divided into five groups of six rats each. The rats were administered with MSG and vitamin C treatments for 65 days. Vitamin C attenuated the MSG induced toxicity on weight of testes and epididymes, sperm motility, count and sperm head abnormality. Vitamin C can actually attenuate the effect of MSG induced toxicity in rats as a model.

Gonadal Responses to Antipsychotic Drugs: Chlorpromazine and Thioridazine Reversibly Suppress Testicular Functions in Albino Rats  

Directory of Open Access Journals (Sweden)

Full Text Available This work was undertaken to investigate the individual effects and probable mechanism of action of chlorpromazine hydrochloride (largactil and thioridazine hydrochloride (melleril on male reproductive functions, in albino rats. A total of 45 adult male albino Wistar-strain rats were used. Five rats served as the control while the remaining forty rats were divided into four groups, of 10 rats each. Rats in group I were treated with 2.3 mg kg-1 BW, while those of group II received 5.7 mg kg-1 BW of chlorpromazine. Rats in group III, were treated with 1.7 mg kg-1 BW, while those of group IV received 2.3 mg kg-1 BW of thioridazine. Control rats received vehicle of the drugs (i.e. distilled water. Drugs and vehicle were administered orally on a daily basis. Five rats, in each of the four drug-treated groups served as the recovery rats. Sperm characteristics evaluation, serum levels of testosterone and histopathological alterations in the testis were assessed both after four weeks of continuous drug administrations and four weeks of drug withdrawal. Chlorpromazine and thioridazine significantly caused a reduction in the absolute weights of the testis, epididymis and seminal vesicles (p<0.01 at high and low doses. Weight of the prostate gland was also reduced significantly (p<0.05 at the high dose. The epididymal sperm motility, viability (life/death ratio and counts were significantly reduced (p<0.01 at high dose of chlorpromazine and thioridazine. Moreover, sperm morphological abnormalities were significantly increased (p<0.01 at both doses of the drugs. Reduction in serum levels of testosterone for both drugs was statistically significant (p<0.01. The histopathological alterations observed in the testis includes moderate to severe degeneration of seminiferous tubular epithelium. Fertility and other associated changes were restored within four weeks of cessation of treatment. Chlorpromazine and thioridazine appear to have reversible antifertility actions in male albino rats. These actions were probably mediated within the testis and epididymis.

Renal Lesions Induced by Pyrethroid Inhalation in Albino Rats  

Directory of Open Access Journals (Sweden)

Full Text Available The effect of pyrethroid inhalation was studied on the kidney of Albino rats. The results revealed that animals inhaled tetramethrin for 15 days showed a significant increase in serum creatinine and blood urea nitrogen. Histological examination of the kidney of treated animals indicated marked symptoms of renal tissues impairment. The renal tubules lost their characteristic appearance and their linning epithelial cells appeared with cytoplasmic vacuolation. The glomeruli were degenerated and the renal blood vessels were congested. The intertubular spaces were infiltrated by inflammatory leucocytic cells. The magnitude of these changes was time-dependent, being more prominent after 15 days of treatment.

The protective role of damsissa (Ambroosia Maritima) against gamma irradiation in albino rats  

International Nuclear Information System (INIS)

The present work was directed to evaluate the effectiveness of treatment with damsissa (Ambrosia maritima) for thirty consecutive days pre- irradiation exposure in controlling the post-irradiation hazards in irradiated rats. Male albino rats (Spraue Dowley strain) weighing about 120+- 10 g were used and blood samples were collected from tails of animals thirty days after treatment with damsissa and seven days post irradiation. Blood samples were subjected to biochemical analysis such as liver functions, kidney function and lipid profile. Whole body gamma irradiation of rats at 6 Gy (single dose) caused significant decrease in the contents of total proteins accompanied by significant increase of urea level as recorded on the 7th days post irradiation. Data obtained in this study revealed that whole body gamma irradiation induced significant elevation in all tested blood lipid functions. There was significant increase of aspartate amino transferase (AST) and alanine amino transferase (ALT) whole alkaline phosphatase (ALP) showed statistical significant decrease as compared with the control group. Damisissa (Ambrosia maritima) treatment exerted noticeable amelioration in the the studied biochemical parameters of the irradiated albino rats. The mechanism of action of damsissa may be due to its anti-inflammatory properties against whole body gamma irradiation

Erythropoietin-Like Effects of Dihydroartemisinin in Wistar Albino Rats  

Directory of Open Access Journals (Sweden)

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.

Male rat sexual behavior.  

Science.gov (United States)

The male rat's sexual behavior constitutes a highly ordered sequence of motor acts involving both striate and smooth muscles. It is spontaneously displayed by most adult made rats in the presence of a sexually receptive female. Although the behavior is important for the survival of the species it is not necessary for survival of the individual. In that way it is different from other spontaneous behaviors such as eating, drinking, avoidance of pain, respiration or thermoregulation. Among other things, this means that it is difficult to talk about sexual deprivation or need. Nevertheless, studies of male sex behavior distinguish sexual motivation (the ease by which behavior is activated, "libido") from the execution of copulatory acts (performance, "potency") (Meisel, R.L. and Sachs, B.D., The physiology of male sexual behavior. In: E. Knobil and J.D. Neill (Eds.), The Physiology of Reproduction, 2nd Edn., Vol. 2, Raven Press, New York, 1994, pp. 3-105 [13]). The hormonal control of male sexual behavior has been extensively studied. It is clear that steroid hormones, androgens and estrogens, act within the central nervous system, modifying neuronal excitability. The exact mechanism by which these hormones activate sex behavior remains largely unknown. However, there exists a considerable amount of knowledge concerning the brain structures important for sexual motivation and for the execution of sex behavior. The modulatory role of some non-steroid hormones is partly known, as well as the consequences of manipulations of several neurotransmitter systems. PMID:9385085

Sphaeranthus indicus attenuates testosterone induced prostatic hypertrophy in albino rats.  

Science.gov (United States)

The present study reports the attenuating effect of Sphaeranthus indicus extracts (SI) on prostatic hyperplasia induced by testosterone in albino rats. In vitro studies were conducted to assess the 5?-reductase inhibitory potential of the petroleum ether, ethanolic and aqueous extracts of SI. A biochemical marker, ?-sitosterol, was isolated and extracts were characterized utilizing HPTLC. Testosterone (3?mg/kg s.c.) was administered to the rats along with the test extracts and isolated ?-sitosterol for a period of 28?days. The weight of the rats, the urine output, serum testosterone concentrations and prostate-specific antigen (PSA) levels were recorded. The prostate/body weight ratio (P/BW) was calculated and histological studies were performed to observe the changes in the histoarchitecture of the prostate. Finasteride was used as a positive control (1?mg/kg p.o.). Sphaeranthus indicus extracts attenuated the increase in the P/BW ratio induced by testosterone in the treated groups. The petroleum ether extract exhibited the best activity, although the ethanol and aqueous extracts also exhibited significant activity. Urine output was also improved significantly, demonstrating the clinical implications of the study. Histological studies, testosterone levels which were measured weekly and PSA levels measured at the end of the study also support claims for the potential use of Sphaeranthus indicus in the treatment of prostatic hyperplasia.

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 organsus body organs

Hepatoprotective effects of Solanum nigrum Linn fruits against cadmium chloride toxicity in albino rats.  

Science.gov (United States)

The present work is aimed to investigate the toxicity of 1/20 LD50 of cadmium chloride (CdCl2) on male albino rats by oral ingestion and to determine the hepatoprotective effect of Solanum nigrum Linn (SN) dried fruits and their ethanolic extract against CdCl2 toxicity using biochemical parameters. Rats were divided into six groups; the first group is control, second group is CdCl2-intoxicated rats, third group is fed with a semi-modified diet with S. nigrum fruits, fourth group rats ingested with dried extract, and intoxicated rats (groups 5 and 6) were treated with fruits and ethanolic extract of S. nigrum, respectively. The results showed that rats exposed to CdCl2 induced remarkable decrease in body weight gain, feed efficiency, and Hb, Hct, RBC, and WBC count and MCHC, but increase in MCV and MCH values. In the case of plasma enzymes, there were significant stimulations observed in ALT and AST, acid phosphatase, alkaline phosphatase, and LDH activities of CdCl2-intoxicated rats (group 2) compared to control (group 1). Plasma protein profile showed decreases in total soluble protein and albumin; also globulin content was decreased by CdCl2 ingestion. Under the same condition, plasma total bilirubin and glucose levels were increased in group 2. In addition, lipid peroxidation and antioxidative system (GSH, catalase, and SOD) of liver were harmed by CdCl2 ingestion. Whereas, normal rats treated with SN showed insignificant changes in groups 3 and 4 as compared to control (group 1). The treatment with dried fruits and their ethanolic extract in CdCl2-intoxicated rats (groups 5 and 6) ameliorated and improved these harmful effects in all above parameters either for blood or liver. The results of this study suggest the protective effect of S. nigrum against liver injury happened by CdCl2 which may be attributed to its hepatoprotective activity and thereby. PMID:25022247

Comparative study on the effect of energy drinks on haematopoietic system in Wistar albino rats.  

Science.gov (United States)

Energy drinks have become popularized and the market value for these drinks is continually growing. Therefore, the present study aimed to evaluate the effect of three popular kinds of energy drinks (Power Horse, Red Bull and Code Red) on certain hematological parameters and on the ultrastructure of blood cells in male Wistar albino rats. Animals were treated orally with Power Horse, Red Bull and Code Red respectively for 4 weeks. Blood samples were taken after two and four weeks for determination of haematological indices. Ultrastructure examination of blood cells was carried only after 4 weeks of treatment. The results indicated significant reduction (P Power Horse and these changes were time dependant. Insignificant changes were recorded in rats administered with Code Red. On the other hand, ultrastructural alterations, including both nucleus and cytoplasm of peripheral blood cells, were recorded in all treated animals but they were more pronounced in animals received Red Bull and Power Horse. It is concluded that energy drinks have serious detrimental impacts on haematopoietic system of male rats. PMID:25204063

Antioxidant Effect of Caffeic Acid on Oxytetracycline Induced Lipid Peroxidation in Albino Rats  

Science.gov (United States)

Caffeic acid is a well-known phenolic compound widely present in plant kingdom. The aim of this study was to investigate the possible protective effect of caffeic acid (CA) against oxytetracycline (OXT) induced hepatotoxicity in male Albino Wistar rats. A total of 30 rats weighing 150–170 g were randomly divided into five groups of six rats in each group. Oral administration of OXT (200 mg/kg body weight/day) for 15 days produced hepatic damage as manifested by a significant increase in serum hepatic markers namely aspartate transaminase (AST), alanine transaminase (ALT), alkaline phosphatase (ALP), lactate dehydrogenase (LDH), bilirubin and increased plasma and hepatic lipid peroxidation indices (TBARS and hydroperoxide). The present finding shows that the levels of enzymatic antioxidants namely superoxide dismutase (SOD), catalase (CAT) and glutathione peroxidase (GPx) were significantly decreased in OXT intoxicated rats. Upon oral administration of caffeic acid (40 mg/kg body weight/day) there were decreased hepatic marker activities, bilirubin and lipid peroxidation and increased enzymatic antioxidants in OXT + Caffeic acid group compared to Normal + OXT group(P < 0.05). Our study suggests that caffeic acid has antioxidant property and hepatoprotective ability against OXT induced toxicity. PMID:21966107

Conditioned partner preference in female rats for strain of male.  

Science.gov (United States)

Female rats show conditioned place preference following paced copulation, and we have recently demonstrated that pairing almond odor with paced copulation induces a conditioned partner preference for almond-scented males. The present study examined whether cues of two different strains of male (albino and pigmented) induce a conditioned partner preference for the strain of male associated with paced copulation. Ovariectomized, hormone-primed Wistar (W) or Long-Evans (LE) female rats received 10 conditioning trials at 4-day intervals. In the Wistar-pacing group females copulated with W males in a chamber bisected by a 4-hole partition that only the female could pass through. Four days later, they copulated with LE males without the partition. The Long-Evans-pacing group received the opposite association. In the final preference test all females chose freely between two males tethered in opposite corners of an open field, one W and one LE. Regardless the strain of male, females displayed more solicitations toward the pacing-related male, and most of the females received their first ejaculation from that male. The preference was facilitated if the pacing-related male was of the same strain as the female. These results suggest that female rats have an unconditioned preference for males of the same strain, but this preference can be switched towards males of a different strain if that male is associated with the sexual reward induced by paced copulation.

Lipid Lowering Efficacy of Pennisetum glaucum Bran in Hyperlipidemic Albino Rats  

Directory of Open Access Journals (Sweden)

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.

International Nuclear Information System (INIS)

The present study was designed to explore the radioprotective potential of lycopene in gamma irradiated male rats. Four groups, each of sixteen rats, were assigned as follows: the first was untreated (control group), the second fed on chow diet mixed with 300 mg lycopene/kg diet (lycopene group), the third exposed to 6.5 Gy gamma radiation (irradiated group) and the fourth fed on chow mixed with 300 mg lycopene/kg and exposed to 6.5 Gy gamma radiation (irradiated and treated group). Animals exposed to ionizing radiation experienced decline in their body weights, increased ALT and AST enzymes and decreased serum albumin level. The study also showed decline in hemoglobin, total white blood cells count and blood platelets count. Bone marrow examination revealed profound hypoplasis and reduction of the cellular elements. Histological examination of liver, spleen, testis and intestine showed disruption of normal architecture of these organs. Irradiated and treated animals maintained a more or less steady body weight, and improved serum ALT, AST and albumin in comparison with those irradiated. The results also showed increased hemoglobin, total white blood cells, platelets count and partial improvement of bone marrow cellularity. Lycopene was also capable of partial preservation of normal architecture of liver, spleen, intestine and testis in gamma irradiated group.In conclusion, lycopene seems to be a useful radioprotector probably because of its potent antioxidant propert because of its potent antioxidant property

Full Text Available Back ground: Diabetes mellitus (DM is a major health problem worldwide in recent time. Asia and Africa are the most viable areas where the disease is feared to raise 2–3 folds. Many herbal products have been recommended for the treatment of DM in ancient literature of Ayurveda in India and other worldwide.Material and method: Thirty male adult albino rats were used to investigate the effect of Catharanthus rosea (C.roseus on diabetic rats. Rats were divided into three equal groups, control, diabetic non treated and diabetic C.roseus treated groups. After thirty days of treatment all rats of each group were sacrificed. The body weight of each rat was determined at the beginning and the end of each period. Blood glucose, serum insulin, lipid and protein profiles, liver and kidney functions, blood picture and liver glycogen were determined for each rat at the end of each period. Pancreatic samples were obtained and processed for microscopic and quantitative evaluation after staining the prepared sections with heamatoxylin and eosin as well as special stain for demonstration of the different pancreatic cells in the islets of Langerhans.Results: The obtained results showed that the diabetic rats were diagnosed by laboratory assessment to body weight loss, hyperglycemia, and hypoinsulinemia, significant increase in liver and kidney functions, lipid and protein profiles and decreased liver glycogen content. While, C.roseus treatment led to a significant improvement in these parameters except liver function. Microscopically there was definite vaculation, degeneration, karyolysis and pyknosis of beta pancreatic cells in the diabetic group, while other pancreatic cells were not affected (alpha and delta cells. The use of C.roseus treatment of this study greatly improves such cellular changes.Conclusion: It was recommended that the use of the water extract of C. roseus levies as a hypoglycemic agent may offer a new hope to the diabetics in future. It's well recommended to use variable doses and different periods of treatment to evaluate the best dose and period

Because this drug has a vasodilatory effect. Sildenafil citrate and ethanol consumption are used in societies world wide and have been identified as injurious to human health. The aim of this study was to evaluate the effects of Sildenafil citrate and Ethanol consumption on lipid and lipoprotein levels in testis tissue and serum of Albino rats. Male Albino rats were divided into eight groups of six animals each and maximum treated for 45 days as follows, control rats were administered with normal saline orally. Sildenafil citrate (1 ?g gm-1 and 18% ethanol (5 g kg-1 body weight was given orally at a single doses (short-term after 1, 2½, 4 and 24 h were sacrificed and 15, 30 and 45 days daily continuous doses (long-term of drug and ethanol with a single dosage were given and to be sacrificed after 4 h of the last dosage. Further, the average total body weight gain was significantly higher in 30 days treatment, but 45 days no significant change in the body weight of the rats were observed due to the productive role of Sildenafil citrate and ethanol. This combination was found to be increased serum cholesterol, triglycerides, LDL and VLDL levels, whereas the levels of serum HDL was found to be decreased as compared with the control rats. Simultaneously tissue cholesterol and triglycerides significantly (p<0.05 inhibited were found to be the rise in lipid and lipoprotein concentrations. Whereas, It is suggested that prolonged exposure to Sildenafil citrate and ethanol administration to rat is found to be increased in lipid and lipoprotein concentrations significantly in an animals.

Group I served as male control group. Group II served as female control group. Group III served as male fansidar alone treated group. Group IV served as female fansidar alone treated group. Group V served as male fansidar and Vitamin C treated group while group VI served as female fansidar and vitamin C treated group. Each rat was housed in a wooden cage. The animal room was ventilated and kept at room temperature and relative humidity of 29°c and 40-70% respectively with 12 hours natural light-dark cycle and were allowed free access to food and water ad libitum. Good hygiene was maintained by constant cleaning and removal of faeces and spilled from cages daily. Rats in all groups were weighed daily and sacrificed 24hours after the experimental periods of 14 days of oral administration and the serum were collected for lipid profile determination. Results: The body weight parameters of both male and female albino rats, showed significant increase (P<0.05 in both the control groups and fansidar + Vitamin C treated group when compared with their initial weights while the group treated with fansidar alone, showed a significant decrease (P<0.05 in weight when compared with the initial weight for both genders. Likewise, the fansidar treated groups showed a significant increase (P<0.05 in serum cholesterol when compared with the control while the fansidar + Vitamin C treated group showed no significant difference in total serum cholesterol when compared with the control. The group treated with fansidar alone showed a significant decrease in serum HDL when compared with the control while the group treated with fansidar + Vitamin C showed a significant increase when compared with the control. The treated groups also produced a significant (P<0.05 decrease in serum LDL, VLDL and TG when compared with the control. Also, in female albino rats, both treated groups produced a significant (P<0.05 decrease in serum total cholesterol when compared with the control. Though the group treated with fansidar alone produce a significant (P<0.05 decrease in serum HDL, a significant increase (P<0.05 was observed in groups treated with fansidar and antioxidant Vitamin C. The group treated with fansidar alone produce a significant (P<0.05 reduction in serum LDL while groups treated with fansidar and antioxidant Vitamin C produced a significant (P<0.05 increase when compared with the control .Likewise, both treated groups produced a significant (P<0.05 decrease in serum VLDL when compared with the control. The serum triglyceride in fansidar treated group was significantly(P<0.05 decreased in fansidar+ Vit.C treated group when compared with the control. Conclusion:The biochemical alterations and responses above from this study are indications that fansidar and Vitamin C exhibits a synergistic reaction which might aid hypocholesterolaemic effect or cholesterol clearing or lowering ability which can reduce the risk of predisposition to atherosclerosis, coronary heart disease and other cardiovascular related disorders.

Regulation of estrous cycle in hysterectomized albino rats by activation of follicular development.  

Science.gov (United States)

Wistar strain albino rats were hysterectomized and the estrous cycle was compared with sham operated controls. Duration of estrous cycle in hysterectomized rats increased markedly with significant delay in the luteal phase and this was correlated to the inhibited follicular development of ovary. When these rats were treated with PGF2 alpha and PMSG and subjected to physical exercises, the estrous cycle was synchronised and the ovaries of such animals had active follicular development. Thus the deranged operation of sexual cycle in hysterectomized rats was regulated through physical exercises. PMID:1478712

Science.gov (United States)

Abstract Background: Acalypha wilkesiana (Euphorbiaceae) is highly accepted for traditional treatment of human plasmodiasis in Africa. Methods: The toxicological effects of the aqueous leaf extract of A. wilkesiana were studied in 45 male and female Wistar albino rats. An acute toxicity testing was done using 21 rats divided into seven groups and LD50 determined. In the sub-chronic toxicity study, the extract was administered orally over a period of 28 days to rats in three groups with doses of 400?mg?kg-1, 800?mg?kg-1 and 1,600?mg?kg-1, respectively, and the fourth group administered with water served as control. Blood samples were collected for hematological and serum biochemical analysis; organs of the animals were harvested for histopathological examination. Results: The acute toxicity testing showed that the extract was non-toxic at doses up to 3,000?mg?kg-1 and the LD50 was calculated to be 2,828.34?mg?kg-1. The study showed that at 1,600?mg?kg-1 dose, the extract caused a decrease in the level of neutrophils (NEUT) while lymphocytes (LYMP) were statistically significantly increased. The administration of the extract also resulted in varying significant dose dependent increase in the levels of aspartate amino transferase (AST), alanine aminotransferase (ALT) and alkaline phosphatase (ALP). There were also significant increases in the level of total protein (TP), urea (URN) and albumin (GLB) especially at 1,600?mg?kg-1 dosage. Histopathology showed that the extract caused mild to severe significant lesions that are dose dependent in the liver and kidney when compared with the control group. Conclusions: Prolonged administration of high dose of A. wilkesiana extract has tendency to cause organ toxicity. PMID:25390027

Full Text Available Introduction: Ketorolac tromethamine is a potent injectable non-steroidal anti-inflammatory drug (NSAID. Ketorolac provides successful analgesia after intrathecal or epidural injection. It is frequently used to manage post-operative pain, cancer pain, and arthritis either intrathecally, or intramuscular. However, its long term administration could induce renal toxicity and/or gastro-intestinal ulceration. Aim of the study: The aim of this study was to assess the analgesic potency of ketorolac after intrathecal injection. Also, we aimed to study the histological effect of ketorolac on the spinal cord and the duodenum after treatment in an animal model. Methods: 40 adult male albino rats, weighing 250-350 gm, were used and divided into 4 groups, 10 rats each. Group S (control received 10l normal saline intrathecally, group K50 received 50g ketorolac intrathecally, group K50 + omeprazole (proton pump inhibitor received 50g ketorolac intrathecally plus 0.2 mg omeprazole orally, and finally, group K100 received 100g ketorolac intrathecally. All animals were treated for four successive days. Result: The rat tail flick latency was longer in K50, K50 + omeprazole, and K100 groups when compared to normal control (P = 0.002. Also, the hind-paw withdrawal latency was longer in treated groups when compared to those of the control group (P = 0.0001. Moreover, K50 group showed decreased phase II response by 61%, K50 + omeprazole group showed decreased phase II by 62%, while K100 group showed decreased it by 76%. Histological examination revealed no changes in the spinal cord of all treated animals. Also, examination of the duodenum showed normal duodenal mucosa in group K50 and those of group K50 + omeprazole. On the other hand, cellular infiltration as well as destruction of the mucous acini have been noticed in the duodenum of K100 group. Conclusion: Ketorolac could be a good alternative drug used intrathecally to manage pain.

Immunolocalization of laminin during postnatal development of the testis, epididymis and vas deferens of albino rat  

Directory of Open Access Journals (Sweden)

Full Text Available Background: Disorders of testicular function may have their origins in fetal or early life as a result of abnormal development. Laminin-1 is emerging as the key molecule in early embryonic basement membrane assembly. Accumulating evidence supported the idea that extracellular matrix (ECM molecules and mesenchymal cells might influence Sertoli and spermatogenic cell functions. Aim of the work: detecting the changes in the distribution and prevalence of laminin-1 assembly during postnatal development of the testis, epididymis and vas deferens in albino rats. Materials and methods: Thirty male albino rats were used and divided into six groups (n= 5 each according to the age (postnatal day. These were one day, 1 week, 2 weeks, 3 weeks, 4 weeks, and 8 weeks postnatal. Specimens were fixed and processed, sectioned and stained by hematoxylin and eosin and immunohistochemical stain for laminin-1. The area percent of positive laminin immunostaining was measured and results were statistically analyzed. Results: at day one postnatal, the testis was formed of solid un-canalized cords of seminiferous tubules with abundant laminin expression in the cells of the cords. With advancement of development the cords were luminized and the laminin expression declined to involve the basement membrane and the apical portions of the Sertoli cells at the 8th week postnatal. The epididymis at postnatal day one had a small diameter and narrow lumen and laminin expression involved the cytoplasm of the epithelial lining. As development proceeded the expression became confined to the apical portion, the site of stereocilia together with its presence in the basement membranes. The same pattern of changes in laminin expression together with morphological appearance was detected in the vas deferens. Conclusion: The present study was able to demonstrate a change in the distribution as well as the prevalence of laminin-1 immunoreactivity within the testis, epididymis and vas. During the period of postnatal development starting at postnatal day one up to 8 weeks postnatal. This would reflect an essential role for laminin in early postnatal period of development

Science.gov (United States)

Antidiabetic, antioxidative, and antihyperlipidemic activities of aqueous-methanolic (2?:?3) extract of Swietenia mahagoni (L.) Jacq. (family Meliaceae) seed studied in streptozotocin-induced diabetic rats. Feeding with seed extract (25?mg 0.25?mL distilled water(-1)100?gm b.w.(-1)rat(-1)?day(-1)) for 21 days to diabetic rat lowered the blood glucose level as well as the glycogen level in liver. Moreover, activities of antioxidant enzymes like catalase, peroxidase, and levels of the products of free radicals like conjugated diene and thiobarbituric acid reactive substances in liver, kidney, and skeletal muscles were corrected towards the control after this extract treatment in this model. Furthermore, the seed extract corrected the levels of serum urea, uric acid, creatinine, cholesterol, triglyceride, and lipoproteins towards the control level in this experimental diabetic model. The results indicated the potentiality of the extract of S. mahagoni seed for the correction of diabetes and its related complications like oxidative stress and hyperlipidemia. The extract may be a good candidate for developing a safety, tolerable, and promising neutraceutical treatment for the management of diabetes. PMID:20981322

Full Text Available To investigate the effect of sub chronic consumption of Periwinkle and Rock snail extracts on liver enzymes and blood in anaemic albino rats was the objective of this study. Twenty-five male and female albino rats were randomly used in the study and were divided into three groups. Anaemia was first introduced into twenty rats after strict corn-meal feeding for three weeks. Group one (5 rats served as control (normal rat feed and water; group two (10 rats-anaemic+rat feed and periwinkle extract; group three (10 rats-anaemic+rat feed and rocksnail extracts. After three weeks, the rats were sacrificed and their blood taken for analysis. In the test for anemia, the result indicated that the rat was anaemic. There was decrease in the blood parameters (Red blood cell, White blood cell, hemoglobin, Pack cell volume when compared with control at p<0.001. The results for serum AST, ALT and ALP level from anaemic-rock snail fed rats revealed that there was significant decrease (p<0.05 in liver enzyme level when compared with the control. This was similar with anaemic-periwinkle extract-fed rats except in ALP level which was significantly increased (p<0.05 when compared with control. Similarly, there was significant increase in the blood parameters (RBCs, WBCs, Hb Concentration and PCV and also differential WBC counts from anaemic extracts-fed rats when compared with control rats. This result reveals that subchronic consumption of rock snail and periwinkle extracts on anemic liver enzymes shows no deleterious effect on the liver enzymes and there was also improved state of the blood cells counts.

Aging-related changes of optic nerve of Wistar albino rats.  

Science.gov (United States)

Aging is a biological phenomenon that involves an increase of oxidative stress associated with gradual degradation of the structure and function of the optic nerve. Gender differences and subsequent deterioration of optic nerve are an interesting topic, especially because there is little published work concerning it. One hundred male and female Wistar albino rats' with ages 1, 6, 18, 24, and 30 months (n?=?20 equal for male and female) were used. At the time interval, optic nerve was investigated by light and transmission electron microscopy (TEM), assessments of antioxidant enzymes (catalase, superoxide dismustase, and glutathione-S-transferase), caspase 3 and 7, malondialdhyde, flow cytometry of DNA, annexin v, and CD8, immunochemistry of vascular endothelial growth factor (VEGF), CD31, and CD45, and single-strand DNA fragmentation. Light and TEM observations of the older specimens (24 and 30 months) revealed apparent deterioration of optic nerve axons, abundant oligodendrocytes with pyknotic nuclei, swollen astrocytes, angiogenesis, vacuolar degeneration, and mitochondrial damage. Females were highly susceptible to aging processes. Concomitantly, there was a marked reduction of antioxidant's enzymes and an increase of lipid peroxidation and apoptotic markers. Old age exhibited a marked increase of G1 apoptosis, UR and LR of annexin V and CD8 as well as increased immuno-positive reaction with VEGR, CD31 and CD45. We conclude that aging contributed to an increase of oxidative stress resulting from damage of mitochondria in axons, oligodendrocytes, and astrocytes. Age-related loss of optic nerve axons is associated with multifactorial agents including reduction in antioxidant enzymes, disruption of vasculature, astrocyte, and oligodendrocyte, demyelination, and damage of mitochondria, which enhance the liberation of reactive oxygen species as assessed by an increase of apoptotic markers malondialdhyde and caspase 3 and 7.

Effect Of Some Slimming Drugs On Haematological And Some Vital Signs Of Albino Rats  

Directory of Open Access Journals (Sweden)

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.

Antidiabetogenic Effects of Separate and Composite Extract of Seed of Jamun (Eugenia jambolana and Root of Kadali (Musa paradisiaca in Streptozotocin-induced Diabetic Male Albino Rat: A Comparative Study  

Directory of Open Access Journals (Sweden)

Full Text Available The present study investigates separate as well as composite methanolic extracts of seed of Jamun (Eugenia jambolana and root of Kadali (Musa paradisiaca for the management of streptozotocin-induced diabetes in rat. As oxidative stress is one of the consequences of diabetes so the present study have measured the activities of some important carbohydrate metabolic enzymes and oxidative stress condition in important visceral organs. After treatment of methanolic extract of above plant parts in separate or in composite manner in streptozotocin-induced diabetic rat resulted a significant recovery in the activities of hexokinase, glucose-6-phosphatase and glucose-6-phosphate dehydrogenase in liver along with correction in fasting blood glucose as well as liver and skeletal muscle glycogen level and plasma insulin level in respect to diabetic group. Activities of catalase and glutathione peroxidase along with the quantity of thiobarbituric acid reactive substance and conjugated dienes in liver and skeletal muscle were also corrected by these plant extracts in respect to diabetic state. The composite extract shows a significant recovery in parameters mentioned earlier than the separate extract. None of the extract has any metabolic toxicity induction in general. From this experiment it may be concluded that the composite extracts of above plants parts have some potential antidiabetogenic activities.

Directory of Open Access Journals (Sweden)

Full Text Available Roselle (Hibiscus sabdariffa calyx was fermented with and without wood ash. The proximate composition revealed that the sample fermented without wood ash had the highest protein content of 14.7 ? 2.5%. There was a significant decrease (P< 0.05 in the antinutrient content (phytate and tannin with a reduction of between 1.21-1.32% in tannin and 488.8?3.7-827.3?3.7mg/100g in phytate. The unfermented sample had phytate and tannin of 2143.6 ? 0.8mg/100g and 5.30 ? 1.1% respectively. The effect of calyx diet on the morphology of the liver was investigated in albino rats. The results suggest that in high doses, roselle calyx may have some toxic effects on the liver. There was decrease in growth in albino rats on all the treatments except for the control diet where there was no increase in growth.

Antiapoptotic and antioxidant effects of carvedilol and vitamin e protect against diabetic nephropathy and cardiomyopathy in diabetic wistar albino rats.  

Science.gov (United States)

Carvedilol is a novel ?-adrenoreceptor blocker, with antioxidant properties inhibiting lipid peroxidation and preventing the depletion of endogenous antioxidants. Moreover, carvedilol was reported to enhance the expression of Bcl-2 gene, which has antioxidant and antiapoptotic effects. There are few researches testing the protective effect of carvedilol on the development of diabetic cardiomyopathy and nephropathy. In this study, we induced diabetes mellitus in male Wistar albino rats. We investigated carvedilol, as well as vitamin E, administrated in healthy and diabetic rats for 6 weeks to compare their effects on biochemical parameters and the expression of Bcl-2 protein in both myocardial and renal tissues by immunohistochemistry. The study showed that the diabetic rats not only had renal dysfunction and more myocardial damage, but also showed lower expression of Bcl-2 protein. Carvedilol and vitamin E treatments were associated with better renal function and less myocardial damage, lower blood glucose, and lipid peroxidation, higher antioxidant capacity, better serum lipids, and higher expression of Bcl-2 protein in diabetic rats. These results indicate that carvedilol and vitamin E treatments partly protect against myocardial and renal damage probably via their antioxidant and antiapoptotic properties in diabetic rats.

Pattern of protein profiles of reproductive organs after induced bilateral cryptorchidism in albino rats.  

Science.gov (United States)

Bilateral cryptorchidism was induced surgically in albino rats and pattern of protein profiles was studied in reproductive organs. Cryptorchidism activated tissue proteolysis leading to overall degradation in soluble and structural protein fractions and in amino acids leading to prevalence of negative nitrogen balance in the reproductive organs. The testicular hypoalbuminic and hypoglobulinic conditions seem to be responsible for oligo-astheno-spermia associated with cryptorchidism. PMID:2409941

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 afct 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

Modulation of antioxidant and phosphatase enzymes by beta-carotene against gamma radiation induced testicular disorders in albino rats  

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 tults 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

Efficacy of oat bran (Avena sativa L. in comparison with atorvastatin in treatment of hypercholesterolemia in albino rat liver  

Directory of Open Access Journals (Sweden)

Full Text Available Introduction: The present study deals with the effect of oat bran (Avena sativa L. in the treatment of hypercholesterolemia in comparison with a hypocholesterolemic drug, atorvastatin, on hypercholesterolemic liver in male albino rats. Material and Methods: For this purpose four groups of rats (each containing 6 rats were used. The first group was used as a control, the second was cholesterol-fed group with cholesterol (0.5% w/w for 6 weeks. The third group was oats-fed hypercholesterolemic rats on oat supplemented diet (20% w/w for 4 weeks and the forth group was atorvastatin-treated hypercholesterolemic rats orally at a dose of 0.18 mg/Kg body weight/day for 4 weeks. Results: The biochemical results revealed a significant increase in serum LDL-C and a significant decrease in HDL-C level. In addition the activity of AST was increased in cholesterol-fed rats. Meanwhile, the treatment with oat soluble fiber or atorvastatin drug improved the above mentioned parameters. The histopathological examination of liver sections of cholesterol-fed group showed accumulation of lipid. Hepatocytes showed ballooning degeneration and manifested clear necrotic signs. Inflammatory cellular infiltration was found around the blood vessels, mild fibrosis near the portal blood vessels. However, liver impairment was reduced markedly in the liver of oat soluble fiber fed rats rather than atorvastatin drug treated rats. Conclusion: The present study, however, confirms that the cereal grain oat may have potent beneficial health effects in reducing LDL cholesterol and should be included in the prudent diet of individuals with hyperlipidemia.

The potential effect of berberine in mercury-induced hepatorenal toxicity in albino rats.  

Science.gov (United States)

Mercury (Hg) is the third most dangerous heavy metal after arsenic and lead. Mercury's toxicity brings serious risks to health through negative pathological and biochemical effects. The study was designed to investigate the possible protective role of berberine (BN) in mercuric chloride (HgCl2) induced oxidative stress in hepatic and renal tissues. Adult male albino Wistar rats were exposed to mercuric chloride (HgCl2; 0.4 mg/kg bwt) for 7 days. Treatment with HgCl2 induced oxidative stress by increasing lipid peroxidation and nitric oxide production along with a concomitant decrease in glutathione and various antioxidant enzymes, namely superoxide dismutase, catalase, glutathione peroxidase and glutathione reductase. HgCl2 intoxication increased the activities of liver enzymes and the bilirubin level, in addition to the levels of urea and creatinine in serum. BN (100mg/kg bwt) treatment inhibited lipid peroxidation and nitric oxide production, whereas it increased glutathione content. Activities of antioxidants enzymes, superoxide dismutase, catalase, glutathione peroxidase and glutathione reductase, were also restored concomitantly when compared to control after BN administration. BN also inhibited the apoptotic effect of HgCl2 by increasing the expression of Bcl-2 protein in liver and kidney. Histopathological examination of the liver and kidney tissues proved the protective effect of BN against HgCl2 toxicity. These results demonstrated that BN augments antioxidant defense against HgCl2-induced toxicity and provides evidence that it has therapeutic potential as hepato- and reno-protective agent.

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 resultO) 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

Camel's Milk Protects against Aluminum Chloride-Induced Toxicity in the Liver and Kidney of White Albino Rats  

Directory of Open Access Journals (Sweden)

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.

Effect of Gamma Radiation on the Albino Rat's Liver and the Possible Protective Role of ?-carotene on the Histological and Ultra Structural Changes  

International Nuclear Information System (INIS)

The Present investigation reports the possible protective effect of ?-carotene against hepatic lesions induced in male albino rats due to gamma-irradiation 48 male albino rats were divided into three main groups; the first served as control (12 animals). Rats of the second group (18 animals) were exposed to a sub-lethal dose of whole body gamma-irradiation and then divided into three equal subgroups. The rats of the third main group (18 animals) received 5 mg/kg body wt of ?-carotene at a daily oral dose for 2 weeks, and were then subjected to whole body gamma-irradiation at sub-lethal single dose level of 6 Gy. This group was then divided into three equal subgroups. The animals were autopsied at three intervals; one week, two weeks and four weeks post irradiation. The obtained data revealed that gamma-irradiation induced different histological changes in the liver of irradiated animals. These changes varied from haemorrhage, congestion in blood vessels, pyknosis and necrosis as well as complete degenerated area in the liver. Electron micrographs recorded swollen mitochondria, fragmented endoplasmic reticulum, distorted nuclei and cell membrane and lipid infiltration in the hepatocytes of irradiated animals. The treatment with ? carotene (5 mg/ kg body wt for two weeks) pre-exposure to radiation attenuated most of these changes. Therefore, the present study has included for the potential use of ?-carotene as a radio protector

Directory of Open Access Journals (Sweden)

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.

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

Effect of Fractionated Low Doses of Gamma Radiation on Some Haematological and Immunological Parameters in Albino Rat  

International Nuclear Information System (INIS)

This study was performed on 30 mature male albino rats to evaluate the direct effect of fractionated low doses (0.5 Gy twice weekly) gamma radiation and delayed effect (one month post-irradiation) on some haematological and immunological parameters. The rats were divided into three equal groups, Control and two whole body gamma-irradiated groups the irradiated groups were subjected to total doses of 4 and 8 Grays over a period of one and two months, respectively. The blood samples and peritoneal macrophages were taken twice from each irradiated rats at the end of their irradiation period and after one month post irradiation. Activated peritoneal macrophages in all groups showed significant decrease as compared to control group denoting that irradiation may cause receptor alteration and/or decrease in the phagocytic power of macrophages lasting for a longer time. Throughout the whole experiment there was wide variation in platelet count with no significant or minimal changes in other blood elements. Moreover, in the post irradiation group after two months irradiation, all the haematological parameters tested, except the Hct, were increased as compared to the control group. These results pointed to that the bone marrow and lymphoid organs of the animals can tolerate fractionated low dose irradiation through rapid recovery and/or compensatory stimulation. The presence of many target cells in the post irradiated group increases the red blood cell fragilitye red blood cell fragility

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 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.

Science.gov (United States)

The possible diuretic effect of the leaf extract of Cecropia obtusifolia, Bertol; used in Costa Rican traditional medicine, was tested on five Sprague Dawley rats in individual metabolic cages. During the control week, distilled water was administered with an intragastric cannula. During the C.obtusifolia week, the rats were given the aqueous leaf extract in a daily dosage of 500 mg/kg, intragastricly. Although, the urinary flow was increased (p < 0.05) by a 20%, there was no statistically significant difference between the following parameters: excretion in urine of osmoles, sodium and potassium; daily ingestion of food and water. The animal weights decreased when C. obtusifolia was used, but only on the fourth day the decrease was significant (p < 0.05). In conclusion, the aqueous leaf extract of C. obtusifolia has a slight diuretic effect. PMID:8731614

Long term creatine monohydrate supplementation, following neonatal hypoxic ischemic insult, improves neuromuscular coordination and spatial learning in male albino mouse.  

Science.gov (United States)

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

Effect of flunarizine on blood glucose levels in normal albino rats through oral glucose tolerance test  

Directory of Open Access Journals (Sweden)

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.

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.)

CURATIVE POTENTIAL OF AQUEOUS EXTRACT OF SCENT LEAF (OCIMUM GRATISSIMUM ON CISPLATIN INDUCED HEPATOTOXICITY IN ALBINO WISTAR RATS  

Directory of Open Access Journals (Sweden)

Full Text Available Cisplatin is an effective chemotherapeutic agent used for a wide variety of tumors, but is reported to be hepatotoxic. In the current study, the dose dependent and time course curative potential of aqueous leaf extract of Ocimum gratissimum (O.G. on cisplatin induced hepatotoxic rats using biochemical and histopathological approaches was evaluated. Male albino wistar rats weighing between 150-200g were randomly separated into four different groups of eighteen (18 rats per group. Rats in group 1 received no cisplatin. Normal saline was administered intraperitoneally (i.p. The rats in group 2 were injected with a single dose of cisplatin (5 mg/kg body weight i.p. Tissue damage was also induced in rats in groups 3 and 4 by a single intraperitoneal-administration of cisplatin (5 mg/kg body weight. After three days, 2ml/kg body weight of 5% and 10% aqueous extract of Ocimum gratissimum were administered to rats in groups 3 and 4 respectively, through the oral route using the gavage once daily for 3, 6, 9 and 12 days. Rats in group 2 were given sterile water in place of the extracts while rats in group 1 were the untreated controls. They were all allowed unlimited access to tap water and growers’ mash. Results showed the extract to cause significant (P? 0.05 dose and time related attenuation in the elevation of serum liver enzyme markers of acute hepatocellular injury (ALT, AST and ALP and increase in serum protein. Cisplatin treatment caused significant increase (P? 0.05 in serum alanine aminotransferase (ALT from 43.03 ± 1.29 to 127.90 ± 0.89 U/L and a decrease (P? 0.05 in serum protein concentration from 93.70 ± 0.61 to 50.43 ± 1.53 g/l. There were considerable decreases (P? 0.05 in body weight and liver weight to body weight ratio in the test animals. However, most of these observed changes were alleviated by prophylactic treatment with aqueous extract of O. gratissimum which was also found to be dose and time dependent (P ? 0.05. The ameliorating effect was further evident through decreased histopathological alterations of liver tissues in the groups treated with aqueous extract of O. gratissimum (5% and 10%. The results from this study indicate that aqueous leaf extracts of O. gratissimum has anti-hepatotoxic action against cisplatin induced hepatic toxicity in rats. Hence the extracts have the potential to be used for the management of hepatopathies and as a therapeutic adjuvant in cisplatin toxicity.

The Side Effects Of The Nonsteroidal Anti-Inflammatory Drug (NSAID Ketoprofen On Histological And Ultrastructural Aspects Of The Kidneys Of Albino Rats  

Directory of Open Access Journals (Sweden)

Full Text Available The present work deals with the effect of the therapeutic dose of the nonsteroidal anti-inflammatory drug, ketoprofen on the microscopic structure of the kidney of the albino rat. The present study also sheds light on the risk of using over-dosage either by mistake or in an unwise attempt at quick relieving the body pain. The intramuscular therapeutic dose of ketoprofen to albino rat was calculated and was found to equal 13.5 mg /kg body weight. Fifty adult male albino rats, Rattus norvegicus were used in the present study. The rats were equally allocated to five groups, each of 10 rats. Rats of the first group were kept as control. Rats of the second & third groups were injected daily with the therapeutic dose of ketoprofen for four and eight successive weeks respectively. Rats of the fourth & fifth groups were injected daily with double the therapeutic dose of ketoprofen for four and eight successive weeks respectively. In rats given the therapeutic dose of ketoprofen daily for four weeks and sacrificed 24 hours after the last dose, light microscope examination showed that Malpighian corpuscles and the kidney tubules revealed signs of degeneration. In rats given the therapeutic dose of ketoprofen daily for eight weeks the histological changes were in progression. A few numbers of glomeruli were increasingly congested and shrunken into dense masses of unrecognized structural details. The luminal borders of the cells lining the proximal convoluted tubules together with their microvilli were damaged. The electron micrographs of ultrathin sections of kidneys of rats given the therapeutic dose of ketoprofen daily for eight weeks showed that the glomerular capillaries were disorganized and occasionally their lining endothelium showed degeneration. The podocytes showed deteriorated and rarefied cytoplasm; and their primary processes were fragmented. Also, the foot processes appeared occasionally broad. In some cells of proximal convoluted tubules the microvilli completely disappeared. Occasionally, these cells gave broad blebs into the tubule lumen which became almost obliterated. The cytoplasm of few cells lining the distal convoluted tubules became moderately rarefied and vacuolated. In animals given double the therapeutic dose for four weeks many kidney glomeruli were fragmented and showed marked congestion and increased mesangium. The parietal walls of Bowman's capsules were damaged. The kidney tubules showed generalized hyalinization. A few numbers of t he tubule lining cells displayed pyknotic nuclei; some nuclei were karyolysed and even vanished. In animals given daily double the therapeutic dose of ketoprofen for eight successive weeks, the glomeruli were sclerotic and necrotic and the kidney tubules showed generalized hyalinization.

Physiological, biochemical and histological alterations induced by administration of imidacloprid in female albino rats.  

Science.gov (United States)

Imidacloprid, a neonicotinoid the newest class of major insecticide has outstanding potency and systemic action for crop protection against piercing and sucking insects pests and also highly effective for control of flea on cats and dogs. The effect of oral administration of two doses of imidacloprid 10 and 20mg/kg/day for 60 days on biochemical parameters, histopathology and protein profile of female albino rat was assessed. Average feed intake was significantly reduced (P<0.01) at 20mg/kg/day. Relative weight of heart and spleen decreased significantly (P<0.05) at higher dose level. Non significant increase in alanine aminotransferase (ALT), aspartate aminotransferase (AST), acid phosphatase (ACP), alkaline phosphatase (AKP) activity was observed in both the imidacloprid treated groups. There was significant decrease (P<0.01, P<0.05) in acetyl cholinesterase (AChE) activity in plasma and brain of both the imidacloprid treated groups. Microscopically, liver tissue of rats treated with higher dose of imidacloprid showed marked dilation and congestion of central vein and degeneration of hepatocytes. The exposure to imidacloprid produced histopathological changes that could be correlated with changes in the biochemical profile of female albino rats. The blood plasma proteins were examined by SDS PAGE. There was no diagnostic difference in the pattern of plasma protein profile of control and treated rats. Based on the present physiological, biochemical and histological studies it is evident that imidacloprid did not produce any significant effects at 10mg/kg/day dose but induced toxicological effects at 20mg/kg/day to female rats.

Effect of a plant origin drug on the biodistribution of 99mTc-DTPA in Wistar albino rats  

Directory of Open Access Journals (Sweden)

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 highly 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.

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

Environmental toxicology: Acute effects of suspended particulate matter (dust on hematological indices of albino rats  

Directory of Open Access Journals (Sweden)

Full Text Available The elemental contents of suspended particulate matter (dust samples from Maiduguri, Nigeria, were determined which showed appreciably high levels for especially Pb, Fe, Cu, Zn, K, Ca, and. Na. Wister albino rats were exposed to graded doses of phosphate buffered saline carried dust particles. The hematological indices of the exposed rats were examined on days 10, 20, 30, and 60 post administrations. White blood cell, red blood cell and hemoglobin counts peaked between days 20 and 30. This observation was markedly so for the higher doses, 1000 and 2000 mg/kg, in contrast to the 500 mg/kg dose. The platelet count however indicated a gradual increase within the study period. Observed changes for these indices from the control values were found significant at 99% confidence level. Possible inhalatory problems are thus anticipated from prolonged accumulation of the dust in the respiratory system.

Effects of Celastrus paniculatus on passive avoidance performance and biogenic amine turnover in albino rats.  

Science.gov (United States)

The effects of an indigenous drug, Celastrus oil, extracted from the seeds of Celastrus paniculatus on learning and memory in a two compartment passive avoidance task was studied in albino rats. The effects on the contents of norepinephrine (NE), dopamine (DA) and serotonin (5-HT) in the brain and on the levels of their metabolites both in the brain and urine were also assessed. Significant improvement was observed in the retention ability of the drug treated rats compared with the saline administered controls. The contents of NE, DA and 5-HT and their metabolites in the brain were significantly decreased in the drug treated group. The urinary metabolite levels were also significantly decreased except for total 3-methoxy-4-hydroxyphenyl glycol. These data indicate that Celastrus oil causes an overall decrease in the turnover of all the three central monoamines and implicate the involvement of these aminergic systems in the learning and memory process.

Directory of Open Access Journals (Sweden)

Full Text Available Olive oil is beneficial effects are not only related to its high content of oleic acid, but also to the antioxidant potential of its polyphenols. In this study, we assess the effects of virgin olive oil on mercuric chloride induced oxidative damage in the liver of rats. Adult male Albinos Wistar rats randomly divided into four groups, were the first was served as a control, whereas the remaining groups respectively treated with: virgin olive oil (2ml/ kg b.w; by gavage, mercuric chloride (0.5 mg/kg body weight i.p and combination of virgin olive oil and HgCl2. Change in liver enzyme activities, thiobarbituric acid reactive substances (TBARS level, antioxidants and reduced glutathione (GSH contents were determined after 2 weeks of experimental period. 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 virgin olive oil 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 virgin olive oil supplementation to mercuric chloride intoxicated rats. Liver histological studies have confirmed the changes observed in biochemical parameters and proved the beneficial role of virgin olive oil. The results clearly demonstrate that virgin olive oil 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.

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.

High Fiber Diet Effect On Haemopoietic And Endocrine System In Irradiated Male Rats  

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.

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, pholin, 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

Effects of Aqueous Extract of Mangifera indica L. (Mango Stem Bark on Haematological Parameters of Normal Albino Rats  

Directory of Open Access Journals (Sweden)

Full Text Available The effects of crude aqueous extract of Mangifera indica (Mango stem bark on body weight and haematological parameters in normal albino rats were investigated. Albino rats of both sexes weighing between 75 g and 125 g were used. At least 14 mL of the test aqueous extract of the plant was administered to each rat in the group for a period of 14 days. Observations showed that the extract of the medicinal plant have some effects on the haematopoietic system manifested by a positive increase in the levels of PCV (haematocrit, erythrocyte, leukocyte, platelet counts and lymphocytes, while the haemoglobin (Hb and neutrophil levels were decreased. The test plant also caused an increase in the weights of the rats. Therefore, it is not possible that its use can advance any adverse effects on haematological parameters.

The Role Of Melatonin In Aluminium Induced Genotoxicity In Female Albino Rats  

Directory of Open Access Journals (Sweden)

Full Text Available Aim of the work, In spite of the wide range of use of aluminium. With the increasing awareness of possible health hazards associated with their use, more attention have been focused on their biological and biochemical activity. Aluminium salts are used as the active antiperspirant in under cosmetics, but the effects of widespread, long term and increasing use remain unknown. Aluminium is known to have genotoxic profile, capable of causing both DNA alterations and epigenetic effects. Melatonin reduces the free radical generation and metal detoxification .This study was planned to determine the effects of melatonin on aluminium induced toxicity in the chromosomes of bone marrow cell . Material and Methods ,Forty female albino rats were used in the present work for the chromosomal analysis. Four groups of adult female albino rats were used in the following way: Group -I, control group; Group-II,50 mg /kg b.wt aluminium orally; Group-III, 50g / kg b.wt melatonin orally and Group- IV, 50 mg /kg b.wt aluminium
