    Objective: To evaluate the effect of different doses of lead acetate (1/20, 1/40 and 1/60 of LD50) on body weight gain, blood picture, plasma protein profile and the function of liver, kidney and thyroid gland. Methods: Male albino rats were divided into four groups, the first group represented the health control animals, while the second, third and fourth groups were ingested orally with sub lethal doses of lead acetate (1/20, 1/40 and 1/60) of the oral LD50, respectively. One dose was ingested every two days during the experimental period (14 weeks) including the adaptation time. Blood was collected and used for all analysis. Results: The results showed that, the ingestion of Pb2+ induced significant stimulation in glutamic-pyruvic transaminase (ALT) and glutamic-oxalacetic transaminease (AST) activity. Also, total soluble protein and albumin contents of plasma were significantly decreased, while the content of globulin was changed by the Pb2+ treatments. The cholinesterase activity was inhibited, but the activities of alkaline and acid phosphates and lactate dehydrogenase were stimulated, while plasma glucose level was elevated as a result of lead acetate intoxication. In case of blood picture, Pb2+ ingestion reduced the contents of hemoglobin and RBCs count of intoxicated rat’s blood and the plasma levels of T3, T4 and blood WBCs count were decreased. Conclusions: It can be concluded that lead acetate has harmful effect on experimental male albino rats. Therefore, the present work advises people to prevent exposure to the lead compound to avoid injurious hazard risk.

  3. PROTECTION ROLE OF CALCIUM THERAPY IN IRRADIATED MALE ALBINO RATS

    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 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

  4. STUDIES ON INDUCED HEPATOTOXICITY IN MALE ALBINO RATS (RATTUS NORVEGICUS)

    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 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

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

    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

    Full Text Available Catharanthus roseus is widely used in Indian Ayurvedic medicine for the treatment of diabetes mellitus. The present study was carried out to investigate the antidiabetic and hyperlipidemic potential of Catharanthus roseus on alloxan induced diabetes in male albino rats. Oral administration of aqueous extract of Catharanthus roseus at a dose of 250 mg, 350 mg, and 450 mg/kg body weight for 30 days to diabetic rats resulted in significant reduction in blood glucose, reduction in lipid profile and also prevented a decrease in body weight. Histological observation demonstrated significant fatty changes and inflammatory cell infiltrates in pancreas of diabetic rats. But, supplementation with Catharanthus roseus to diabetic rats significantly reduced the fatty changes and inflammatory cell infiltrates.

  17. Antioxidant activity of eggplant (Solanum melongena) in male albino rats exposed to gamma irradiation

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

    2012-01-01

    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.

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

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

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

    2016-06-01

    Ginger or Zingiber officinale which is used in traditional medicine has been found to possess antioxidant effect that can control the generation of free radicals. Free radicals are the causes of renal cell degeneration that leads to renal failure in case of gentamicin induced toxicity. This study was done to evaluate the possible protective effects of 6-gingerol as natural antioxidant on gentamicin-induced renal cortical oxidative stress and apoptosis in adult male albino rats. Forty adult male albino rats were used in this study and were randomly divided into four groups, control group; 6-gingerol treated group; gentamicin treated group and protected group (given simultaneous 6-gingerol and gentamicin). At the end of the study, blood samples were drawn for biochemical study. Kidney sections were processed for histological, and immunohistochemical examination for caspase-3 to detect apoptosis and anti heat shock protein 47 (HSP47) to detect oxidative damage. Gentamicin treated rats revealed a highly significant increase in renal function tests, tubular dilatation with marked vacuolar degeneration and desquamation of cells, interstitial hemorrhage and cellular infiltration. Immunohistochemically, gentamicin treated rats showed a strong positive immunoreaction for caspase-3 and anti heat shock protein 47 (HSP47). Protected rats showed more or less normal biochemical, histological, and immunohistochemical pictures. In conclusion, co-administration of 6-gingerol during gentamicin 'therapy' has a significant reno-protective effect in a rat model of gentamicin-induced renal damage. It is recommended that administration of ginger with gentamicin might be beneficial in men who receive gentamicin to treat infections. PMID:27036327

  1. Stable Cesium Toxicity and Effect of Prussian Blue in Growing Male Albino Rats

    The present study was carried out to asses the toxicological effects of stable cesium chloride (CsCl) on growing male albino rats and to evaluate the therapeutic role of Prussian blue (PB) administration for modification of the chemical toxicity. The experiments were performed on 32 growing male albino rats, (Rattus Rattus), divided into control group and three groups administered a daily dose of CsCl or PB or both. The results revealed that the intake of stable cesium chloride caused a significant decrease in the Hb concentration, Ht %, serum folic acid, vitamin B12, potassium levels and body weight gain, with significant increase in WBC's count, serum urea and creatinine. No effect was observed on the other studied parameters including: RBCs count, liver functions, blood glucose, phosphokinase, and lactate dehydrogenase. On the other hand, PB caused a significant amelioration in the changes produced by CsCl with variable degrees leading to the conclusion that it can be one of the therapeutic agents that might provide a protection against toxicological effects

  2. THE POSSIBLE EFFECT OF SILDENAFIL CITRATE AND FENUGREEK SEED POWDER ON ENHANCING SERUM TESTOSTERONE LEVELS IN ADULT MALE ALBINO RATS

    Sildenafil citrate is a phosphodiesterase 5 inhibitor (PDE5) that increases cyclic guanosine monophosphate (cGMP) which improves vasodilatation and there is a hypothesis that fenugreek seeds have 3 mechanisms by which it may enhance serum testosterone levels. The present study aimed to evaluate the effect of sildenafil citrate and fenugreek seeds alone or in combination on serum testosterone levels in normal adult male albino rats. Besides, total protein, albumin, globulin, bilirubin levels and alanine transaminase, aspartate transaminase and alkaline phosphatase activities were evaluated. The present study claimed that single or combined treatment with sildenafil and fenugreek seed powder (FSP) may enhance serum testosterone levels in adult male albino rats

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

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

    Full Text Available The present investigation was performed to study the effect of daily administration (interperitoneal injection of synthetic coloring agent amaranth at dose 50 mg /kg b.w. /day for two periods (7 and 21 days, using male albino rats. The effects of amaranth on growth, haematological and some biochemical parameters were examined throughout the study. The results revealed that amaranth treatment cause a marked change in treated groups when compared with control. They showed a significant decrease in percentage of body weight change, RBCs count, Hb concentration and HCT value, while, they recorded a significant increase in WBCs, serum activity of AST and ALP, in addition to serum urea and creatinine levels in treated rats. But ALT and bilirubin showed insignificant changes throughout the experiment.

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

    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

  7. Nigella sativa oil Ameliorates ionizing Radiation induced cellular injury in Male Albino Rats

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

  10. Effect of salvia Egyptiaca extract on cholinergic system in adult male albino rats

    The daily oral administrations of Salvia aegyptiaca extract, equivalent to 2 g/kg body weight for 4 weeks, caused significant decrease in acetylcholine esterase activity in whole blood and in all tested brain areas (cerebellum, pons + medulla oblongata, striatum, cerebral cortex, hypothalamus, midbrain and hippocampus) of male albino rat nearly all over the experimental period. Treatment with Salvia aegyptiaca extract also resulted in significant increase in acetylcholine content in the cerebral cortex and hippocampus' nearly throughout the whole experimental period. It could be concluded from the present results that the extract of Salvia aegyptiaca caused an increase in acetylcholine content and this increase may be due to the decrease in the activity of acetylcholine esterase enzyme which play an important role in the treatment of Alzheimer's disease

  11. Effect of granulosis virus (virotecto) as bioinsecticide on some biochemical changes in male albino rats

    The objective of this study to determine the biochemical response of granulosis virus in male albino rats fed with potato treated with granulosis virus (0.15 g/Kg) against potato tuber moth in stores .It was carried out by evaluating the effect of daily feeding on treated potato for 5 weeks followed by withdrawal period for 10 days fed with normal diet on some biochemical and histological changes in kidney of male rats. A trail consists of 3 groups each one contain 18 rats, the first group fed on normal basal diet and served as control, the second group fed with 50% normal potato and 50% basal diet (potato group) and the third group fed with 50% basal diet and 50% potato treated with granulosis virus (virus group) through the experimental period. The obtained data revealed a significant reduction in final body weight and organs weight in both normal and treated potato groups. Sera collected at 2 and 5 weeks post feeding and at the end of withdrawal period, recorded significant disorders in some tested parameters. In addition, histological examination of kidney tissue showed different disorders in normal and treated groups.

  12. Possible Role of Humoral Immunity on Liver Dysfunction in Male Albino Rats

    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.

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

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

    Cadmium toxicity can disturb brain chemistry leading to depression, anxiety, and weakened immunity. Cadmium disturbs the neurotransmitter dopamine, resulting in low energy, lack of motivation, and depression, which are predisposing factors for violence. The purpose of this study was to evaluate the ameliorative effect of grape seed extract (GSE) on the brain of 40 male albino rats after exposure to cadmium chloride (Cd) toxicity. The rats were separated into either the control group, the Cd group, the GSE group, or the GSE and Cd mixture (treated) group. The cerebrum showed evidence of degeneration of some nerve fibers and cells. Fibrosis, vacuolations, and congestion in the blood vessels were demonstrated. Satelletosis was located in the capsular cells. Immunohistochemical expression of Bax was strongly positive in the Cd group and decreased in the treated group. These histopathological changes were decreased in the brain tissue of the treated group, but a few blood vessels still had evidence of congestion. Cadmium administration increased the level of MDA and decreased MAO-A, acetylcholinesterase, and glutathione reductase (GR), while the treatment with GSE affected the alterations in these parameters. In addition, cadmium downregulated the mRNA expression levels of GST and GPx, while GSE treatment normalized the transcript levels. The expression of both dopamine and 5-hydroxytryptamine transporter was downregulated in the rats administered cadmium and the addition of GSE normalized the expression of these aggression associated genes.

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

    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

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

    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

  17. In Vivo Internal Decontamination of 134Cs and 60Co from Male Albino Rats

    The Present work aimed to evaluate the therapeutic role of prussian blue (PB), vermiculite and calcium trisodium salt of diethylenetriaminepentaacetic acid (DTPA) as internal de contaminants of radio-active cesium and/ or cobalt in adult male albino rats. Radionuclides were given as a single doses; 60Co was introduced orally, subcutaneously or intraperitoneally (ip) while 134Cs was taken orally or in combination with ip injection of 60Co. The de contaminants were supplied daily for three weeks immediately after 60Co or 134Cs intake; oral dose of PB + vermiculite treated the oral 134Cs group, oral and subcutaneous 60Co groups and combined 60Co and 134Cs groups. Rats receiving ip dose of 60Co were treated with daily ip dose of DTPA while the three de contaminants were added to the combined 60Co and 134Cs groups.Haemoglobin concentration (Hb), haematocrite percentage (Ht), red blood cells count (RBC's), as well as liver function tests (total bilirubine, total protein, albumin, globulin, A/ G ratio, alanine transaminase (ALT), spartic transaminase (AST) and alkaline phosphatase (ALP)) were analyzed in all groups. The data obtained revealed that internal contamination by radioactive materials causes a significant decrease in the RBC's counts, Hb concentration, haematocrit value, serum total proteins and albumin. On the other hand, the therapeutic agents caused a significant amelioration in the changes produced by internal contamination with variable degree. Thus, it could be concluded that the therapeutic agents might provide a protection against internal contamination hazards

    Full Text Available Objectives: To study the effect of acute and repeated dose administration of lyophilized aqueous extract of the dried fruits of Tribulus terrestris (LAET on sexual function in sexually sluggish male albino rats. Materials and Methods: Aphrodisiac activity of the test drug was evaluated in terms of exhibited sexual behavior. In order to assess the effect of chronic T. terrestris exposure on the hypothalamus--pituitary--gonadal axis, testosterone level estimation and sperm count were carried out. Twenty-eight-day oral toxicity studies were carried out to evaluate the long-term effects of the LAET administration on different body systems. Results: A dose-dependent improvement in sexual behavior was observed with the LAET treatment as characterized by an increase in mount frequency, intromission frequency, and penile erection index, as well as a decrease in mount latency, intromission latency, and ejaculatory latency. The enhancement of sexual behavior was more prominent on chronic administration of LAET. Chronic administration of LAET produced a significant increase in serum testosterone levels with no significant effect on the sperm count. No overt body system dysfunctions were observed in 28-day oral toxicity study. Conclusions: Findings of the present study validate the traditional use of T. terrestris as a sexual enhancer in the management of sexual dysfunction in males.

    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

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

    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% 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

    The shade-dried powder of leaves of Plectranthus amboinicus (Lour) Spreng was subjected to successive extraction using the various solvents (petroleum ether, chloroform, ethanol and water) in increasing order of polarity. The preliminary phytochemical analyses were carried out for all the extracts. The analyses of the leaves revealed the presence of alkaloids, carbohydrates, glycosides, proteins, amino acids, flavonoids, quinine, tannins, phenolic compounds and terpenoids. Since the phytoconstituents present in the ethanolic and aqueous extracts were similar, both the extracts were selected for further study. The diuretic properties of ethanolic and aqueous extracts were evaluated by determination of urine volume and electrolyte concentration in male albino rats. Furosemide (10 mg/kg) was used as standard while normal saline (0.9%) was used as control. Both ethanolic and aqueous extracts (500 mg/kg) have shown significant increase in the volume of urine and urinary concentration of Na, K and Cl ions. Thus, from the is study it may be concluded that the leaves of P. amboinicus (Lour) Spreng possess diuretic activities. PMID:21808546

    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.

  6. Nigella sativa oil for the control of irradiation induced disorders in serum protein components of male albino rats

    The effect of whole body gamma irradiation at the dose level 7 Gy delivered as shot dose or cumulative doses, on the electrophoretic pattern of serum protein components, was studied in male albino rats subjected to Nigella sativa treatment. Sodium dodecyl sulphate- polyacrylamide gel electrophoresis (SDS-PAGE) of serum proteins of irradiated rats showed significant increases in percentages of some fractions of high molecular weights. Administration of nigella sativa oil before radiation exposure resulted in detectable radioprotective effect. Radiation protection effect exerted by nigella sativa oil prior to cumulative doses was more pronounced than that in case of one shot dose

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

    Recent studies demonstrated the role of vitamin C as antioxidant in alleviating organ damage caused by gamma irradiation. The present study was conducted to find out the effect of vitamin C on liver biochemical functions such as serum ALT, AST, albumin and bilirubin after experimental liver damage induced by gamma irradiation. Rats irradiated with gamma radiation were used as a model of liver injury terminating with necro inflammatory activity and acute hepatitis. Forty male albino rats were classified into 6 groups (G0-G5). G0 included 8 male albino rats that were divided to 2 subgroups (4 rats/subgroup). Both subgroups were exposed to gamma irradiation with 6 Gy as a single dose. The first subgroup was left for 3 weeks then serum and liver samples were collected while in the second subgroup, 2 rats were died and the remaining 2 rats were left for 6 weeks then serum and liver samples were collected. G1 was the negative control while in the rest groups, the whole body of rats was exposed to gamma irradiation of dose 8 Gy divided to 2 doses (4 Gy/one dose) at one week interval in between. G2 included 12 albino rats divided into 3 subgroups (4 rats/subgroup). The whole body of albino rats of G2 was exposed to 8 Gy gamma irradiation that divided as mentioned before. Serum and liver samples were collected after one day, two days and four days after last dose of irradiation. G3 also included 8 rats that were divided into 2 subgroups (4 rats/subgroup) and whole body was exposed to 8 Gy gamma irradiation that were divided as mentioned before. Serum and liver samples were collected after one week for one subgroup and 2 weeks for other subgroup after last dose of irradiation. The rest 2 groups (4 rats/group) were exposed to 8Gy gamma irradiation divided as before, but the rats in one group were orally supplemented with low dose of vitamin C. G4 and the others were supplemented with high dose of vitamin C for 2 weeks starting after last dose of irradiation (G5) then serum

    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.

    Full Text Available Background: Naphthalene (NA is a common environmental contaminant and is abundant in tobacco smoke. Rosemary (Rosmarinus officinalis is a herb commonly used as a spice and flavoring agents in food processing and is useful in the treatment of many diseases. Aim of the work: To study the nephrotoxicity of NA and to evaluate the possible protective role of rosemary extract in adult male albino rat. Materials and Methods: 25 animals were divided into three groups: Group I (Control group, Group II (NA treated group received NA at a dose of 200 mg/kg/day dissolved in 5 ml/kg corn oil orally by gastric tube, Group III (protected group received rosemary extract (10 ml/kg/day followed after 60 min by NA at the same previous dose orally by gastric tube. The experiment lasted 30 days. The following parameters were studied: Biochemical assessment of renal function, histological, immunohistochemical, morphometric studies and statistical analysis of the results. Results: NA treatment resulted in a highly significant increase in the mean values of serum urea and creatinine. NA induced histological changes in the form of glomerular congestion. Some glomeruli demonstrated marked mesangial expansion and hence that Bowman's spaces were almost completely obliterated. Shrinkage of renal glomeruli with widening of Bowman's spaces could also be seen. Focal tubular dilatation with appearance of casts inside the tubules was observed. Congested peritubular blood vessels and interstitial hemorrhage were also seen. The medullary region demonstrated vascular congestion and fibrosis. Focal cellular infiltration was presented in the interstitium. The renal cortex of NA treated rats showed a noticeable down regulation in alkaline phosphatase positive immunoreactive cells in some proximal convoluted tubules. NA induced up regulation of positive immunoreaction for inducible nitric oxide synthase in the proximal and distal convoluted tubules as well as in the collecting tubules

    The present study aimed to investigate the therapeutic effect of curcumin on hypertension and its putative mechanisms in the cerebral microcirculation. The surgical preparation was made to generate a cranial window for observation of the capillary network in the cerebral cortex region. Digital image processing, intravital videomicroscopy, and laser Doppler flow meter were used in this investigation. The number of open capillaries, arterial blood pressure, red cell velocity, microvascular diameter, circulating endothelial cells, relative blood flow and frequency were determined. Control rats showed severe dysfunction in the microcirculation with increased blood pressure. In curcumin treated mice, the blood pressure significantly reduced compared to their respective controls. Curcumin significantly increased blood velocity and LDF flow in hypertensive and normotensive rats. Curcumin significantly altered the circulating endothelial cells and open capillaries number in the male albino rats. Our results suggested that the curcumin exerts its therapeutic effect in male albino rats by regulating vasomotion function, increasing blood perfusion, releasing the peripheral resistance and opening efficiently capillaries. Taking all these data together, it is concluded that the curcumin might be useful in the regulation of the cerebral microcirculatory function and hypertension. PMID:27017961

    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.

    2005-11-01

    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 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

  16. Synergistic Effects of Squalene and Omega-3 on Lipid Peroxidation and some Antioxidants in Gamma-Irradiated Male Albino Rats

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

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

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

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

    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 metabolism

    Aim: To evaluate the phytochemical constituents and the aphrodisiac potential of the aqueous extract of Fadogia agrestis (Rubiaceae) stem in male albino rats. Methods: The aqueous stem extract of the plant was screened for phytochemical constituents. Male rats were orally dosed with 18 mg/kg, 50 mg/kg and 100 mg/kg body weight,respectively, of the extract at 24 h intervals and their sexual behavior parameters and serum testosterone concentration were evaluated at days 1, 3 and 5. Results: Phytochemical screening revealed the presence of alkaloids and saponins while anthraquinones and flavonoids are weakly present. All the doses resulted in significant increase in mount frequency, intromission frequency and significantly prolonged the ejaculatory latency (P < 0.05) and reduced mount and intromission latency (P < 0.05). There was also a significant increase in serum testosterone concentrations in all the groups in a manner suggestive of dose-dependence (P < 0.05). Conclusion: The aqueous extract of Fadogia agrestis stem increased the blood testosterone concentrations and this may be the mechanism responsible for its aphrodisiac effects and various masculine behaviors. It may be used to modify impaired sexual functions in animals, especially those arising from hypotestosteronemia.

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

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

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

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

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

  8. Beta-glucan ameliorates gamma-rays induced oxidative injury in male Swiss albino rats

    1,3-beta-D-Glucan is a natural polysaccharide derived from the cell walls of bakers yeast Saccharomyces cerevsiae with immunoenhancing and potent antioxidant effects. This study investigated the pathways through which beta-glucan gavage treatment (50mg/kg) exerts its effect on radiation-induced oxidative damage in male rats. Beta-glucan was given orally to male rats; 3 hours post gamma-irradiation at dose 5Gy, for 10 and 20 days post-irradiation level were assayed, being remarkable indicators in cell oxidative stress. Results pointed out that irradiation at 5Gy significantly depressed all blood parameters, such as erythrocytes count (RBCs), hemoglobin content (Hb), hematocrit value (Hct), total leucocytes count and absolute lymphocytes and neutrophils counts, blood glutathione (GSH) level and conversely elevated level of serum ascorbyl radical (AsR), product of lipid peroxidation (MDA melanodialdehyde), triglycerides and cholesterol. Total leucocytes count and absolute lymphocytes and neutrophils counts, RBCs, Hb, Hct, blood GSH and serum MDA of irradiated animals receiving beta-glucan administration were exhibited significant differences compared to the irradiated group. Marrow count and the percentage of viability and spleenocytes viability were also significantly decreased. Beta-glucan treatment accelerates recovery of cell damage induced by ionizing irradiation through its potential immune-enhancing activity and free radical scavenging ability that is partially mediated through stimulation of immunohaematological system thus could play a role in regulating irradiation complications

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

    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, Δ5-3β hydroxysteriod dehydrogenase (Δ5 -3β-HSD) and 17β hydroxysteroid dehydrogenase (17β -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 Δ5 -3β-HSD, 17 β-HSD activities and gametogenesis

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

    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-α 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-α and IL-6. DNA% fragment migration showed that worse significant migration of DNA fragements were observed in toxicated group(GII) followed by increase in

    Cadmium (Cd) is a highly toxic, nonessential heavy metal with many industrial uses that can contribute to a well-defined spectrum of diseases in animals as well as in humans. The present study examines the effect of zinc (Zn) and iron (Fe) supplementation on oxidative stress enzymes in Cd-treated rats. Wistar strain male albino rats were treated with cadmium chloride (CdCl2) at a dose of 1/10th LD50/48 h, that is, 22.5 mg/kg body weight for 7, 15, and 30 days (d) time intervals. The 15d Cd-tr...

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

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

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

    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 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.

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

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

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

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

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

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

    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

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

    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

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

    The consumption of foods and beverages containing additives has intensely increased over the past decades. Monosodium glutamate (MSG) is one of the main flavor enhancer that can be consumed in high concentrations. Also, human exposure to ionizing radiation (RAD) has become inevitable with its vast application in diagnosis and industry. Humans are frequently exposed to RAD and MSG from various food additives, therapeutic treatments and the environment. Although the use of additives and exposure to RAD in therapeutic treatments are believed to be relatively safe, their combined effects remain unclear. The present study proposed to investigate neurotoxic potentials of exposure to MSG and/or RAD on oxidative stress, neurotransmitters disturbance and metabolic disorders in the rat’s brain tissue. MSG was supplemented daily by gavages to rats at a dose of 450 mg/Kg bwt/day (equivalent to 5 g/day human consumption) for 7 days pre- and 21 days post-exposure to whole body gamma rays at doses of 2 Gy/week up to a total dose of 8 Gy. Exposure to MSG and/or RAD -induced oxidative stress, neurotransmitters disturbance and metabolic disorders. Oxidative stress was manifested by a significant increase in lipid peroxidation product malondialdehyde (MDA) and decrease in the activity of antioxidant enzymes, superoxide dismutase, catalase and glutathione content. The administration of MSG daily during exposure to gamma radiation has potentiated oxidative stress regarding each single treatment. MSG-exposure induced a highly significant decrease of serotonin (P<0.01) and a slight non significant increase (P>0.05) of aspartic and glutamic acids levels while in RAD- group the decrease of serotonin and the increase of amino acids were very highly significant (P<0.001). MSG + RAD-exposure had potentiated the decrease of serotonin and produced an additive effect on the increase of neurotransmitters amino acids. MSG as well as RAD-exposure increased (P<0.05) glucose and insulin levels with

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

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

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

    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 .

    Full Text Available Background: Cancer is a disease that evokes wide spread fear among people and is one of the leading causes of deaths in the world. Diethylnitrosamine (DEN is a known carcinogen in rodent liver. DENs reported to undergo metabolic activation by cytochrome P450 enzymes to form reactive electrophiles that cause oxidative stress leading to cytotoxicity, mutagenicity and carcinogenicity. Objective: The present study was carried out to evaluate the antioxidant activity of ethanolic extract of Tinospora cordifolia (EETC in N-nitrosodiethylamine (DEN induced liver cancer in male Wister albino rats. Materials and Methods: The antioxidant activity was assessed by the levels of lipid peroxidation (LPO, enzymic and nonenzymic antioxidants. Result: A significant levels of LPO was increased as the enzymic and nonenzymic antioxidants values were decreased in liver cancer bearing animals. Conclusions: The administration of EETC to cancer bearing animals reverted the LPO levels, enzymic and nonenzymic antioxidants to near normal

  8. The Modulatory Role of Echinacea Purpurea in Gamma Radiation Induced Physiological and Histological Changes in the Liver and Testis of Male Albino Rats

    Echinaceae purpurea (EP) is one of the most popular herbal medicines used for many years as a panacea for a variety of diseases. The aim of the present study was to evaluate the modulator role of Echinacea purpurea (EP) in some radiation-induced biological damage. Male albino rats were whole body gamma irradiated with 3 Gy delivered as a single shot dose. EP was administered to rats (50 mg/kg body weight) via gavages during four weeks either pre- or post-irradiation. Histological investigations in the liver of irradiated rats revealed degeneration of portal vein area, necrotic hepatic cells and pyknotic nuclei, vacuolated cytoplasm. Testis tissues showed necrotic spermatogenic, degenerated interstitial cells and severe atrophid spermatogonia. The histopathological changes in both tissues were associated with severe oxidative stress denoted by an increase of thiobarbituric acid reactive substances (TBARS) level and a decrease of superoxide dismutase (SOD) and catalase activities as well as glutathione (GSH) content. Alteration in serum lipid profile, glucose level, transaminase activities and testosterone level were also recorded. Administration of EP to rats either pre- or post-irradiation has significantly attenuated radiation-induced oxidative stress which was associated with significant regeneration of liver and testis tissues. It could be concluded that EP may act as a prophylactic as well as a therapeutic agent, however, its role was more pronounced when administered before irradiation which could be attributed to its free radicals scavenging activities.

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

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

    Full Text Available Tramadol is a synthetic opioid analgesic. It is commonly prescribed for moderate to severe pain, becoming abused more popular among teens in most countries. Paracetamol as anti-inflammatory drugs (acetaminophen (APAP is widely used as an analgesic and antipyretic agent. Meanwhile, tramadol/acetaminophen (tramacet is effective in acute or chronic moderate-to-moderately severe pain. In comparative study, the current investigation threw the light on the effect of over doses of tramadol and/or APAP on the immune function and hepatocytes in adult male Sprague-Dawley rats. Material and methods: Treated rats received oral doses of each drug for 15 consecutive days and after last treatment, they kept three days later for withdrawal studies. The rats were divided into four treatment groups, in the first group, rats received saline and used as control. The second, third and fourth groups treated with tramadol (45 mg/kg, tramadol/APAP (45/450 mg/kg, APAP (450 mg/kg respectively, once a-day at the first week and ending with 90, 90/900, 900 mg/kg at the second week. Rats were sacrificed at the end of the first, second weeks and three days of last treatment. Results: Daily doses of tramadol and /or APAP exposure in rats decreased the cellularity of spleen. Moreover, phagocytic and killing of S. aureus by PMN and macrophage cells caused a highly significant decrease in treated groups. IFN- was reduced in a statistically different treated group of rats. Serum IL-10 was unaffected by any of the treatment regimens but increased only in tramadol/APAP treated rats. Spleen histology exhibited mild pathological alteration with different injures between treated groups. Splenic white pulp accompanied by ill deformed which reflected the reduction of white pulp zones, thickened vasculature in the splenic net work, fibrous trabeculae become prominent feature, where splenic red pulp occupied large areas of the splenic network with predominant edema and megakaryocytes.

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

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

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

The fourth group received 0.57 mg/kg b.w. of testosterone hormone via intramuscular injection through two weeks. The fifth group received the same dose of both hormones (Melatonin & Testosterone for two weeks. Some biochemical parameters of the kidney, the thyroid and histological structure of the testis were examined. Results The untreated aged group showed insignificant change in urea level with highly significant decrease in creatinine, T3 and T4 hormones levels. 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

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

    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.

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

    Naglaa Gamil Shehab

    2014-01-01

    Full Text Available 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.

    Samir, A.M. Zaahkouk* ; Eman, G.E. Helal

    2000-12-01

    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.

    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

  19. Role Of Ginkgo BILOBA Extract In Ameliorating The Toxicity And Distribution Of 14C-Carbon Tetrachloride In Some Brain Areas Of Adult Male Albino Rats

    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 data obtained could recommend that EGb-761 has a protective and therapeutic effect against toxicity produced by CCl4.

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

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

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

    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 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

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

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

  6. 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

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

    Liver cancer is the fifth most common cancer and is still one of the leading causes of death world wide, due to food additives, alcohol, fungal toxins, air, toxic industrial chemicals, and water pollutants. Chemopreventive drugs play a potential role in liver cancer treatment. Obviously in the production of anticancer drugs, the factors like poor solubility, bioavailability, biocompatibility, limited chemical stability, large amount of dose etc., plays a major role. Against this backdrop, the idea of designing the chemopreventive nature of bio flavanoid hesperetin (HP) drug conjugated with pegylated gold nanoparticles to increasing the solubility, improve bioavailability and enhance the targeting capabilities of the drug during diethylnitrosamine (DEN) induced liver cancer in male wistar albino rats. The dose fixation studies and the toxicity of pure HP and HP conjugated gold nanoparticles (Au-mPEG(5000)-S-HP) were analysed. After concluded the dose fixation and toxicity studies the experimental design were segregated in six groups for the anticancer analysis of DEN induced HCC for 16 weeks. After the experimental period the body weight, relative liver weight, number of nodules and size of nodules, the levels of tumor markers like CEA, AFP and the level of lipid peroxidation, lipid hydroperoxides and the activities of antioxidant enzymes were assessed. The administration of DEN to rats resulted in increased relative liver weight and serum marker enzymes aspartate transaminase, alanine transaminase, alkaline phosphatase, lactate dehydrogenase, and gamma glutamyl transpeptidase. The levels of lipid peroxides elevated (in both serum and tissue) with subsequent decrease in the final body weight and tissue antioxidants like superoxide dismutase, catalase, reduced glutathione, glutathione peroxidise, and glutathione reductase. HP supplementation (20 mg/kg b.wt) significantly attenuated these alterations, thereby showing potent anticancer effect in liver cancer and the

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

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

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

    2001-09-01

    Full Text Available The antifertility effects of a- chlorohydrin were re-investigated in female albino rats. a.i/Kg. bw of and six females were ! " #$ The uterine changes were in the form of an increase lumenal folding with areas of metaplasia, some cellular vaculization and increased the collogen deposition in the % $ &!rd "th day of the drug intake. The ovarian changes were in the form of decreased number of growing follicles and absence of both Graafian follicles and corpora lutea. It is clear that, treatment of female rats with a chlorohydrin caused reversible uterine and ovarian changes. Uterine changes took longer time to recover compared with that of ovarian changes. These results support the possibility that this drug could be a functional female sterilant as it was known as a male sterilant.

  15. Hepatotoxicity of ingested uranium in albino wistar rats

    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 γ-glutamyltransferase (GGT), alkaline phosphatase (ALP), serum glutamic pyruvic transaminase (SGPT) and serum glutamic oxaloacetic transaminase (SGOT). In addition, histopathological examination of liver tissue was performed. Significant reduction by 61 and 46 % in GGT levels in female rats of groups 4 and 5 respectively while in male rats, increase of 55, 52 and 40 % in groups 3, 4 and 5 respectively were observed compared to control. In females, ALP levels were decreased by 38 % in group 2 and 29 % in group 4 while no changes were observed in males of control and test groups. SGPT level was decreased by 22 % in group 6 in females but increased by 29 and 35 % in groups 2 and 6 respectively in males, compared to control. In females, 25 % increase in SGOT levels in group 4 was observed, but decreased in group 5 and 6 by 26 and 22 % respectively. A 27 % increase in SGOT level in males was recorded in group 2 compared to control. No histopathological changes were observed in liver tissues of test groups or the control.

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

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

    2012-01-01

    Full Text Available Background: Antioxidant properties of Crataeva nurvala bark contains a variety of the bioactive phytochemical constituents in medicinal plants which include flavonoids, phenolic compounds, tannins, anthracene derivatives, and essential oils. Components from Crataeva nurvala bark have been accounted to play an important role in scavenging free radicals generated by mutagens and carcinogens. Androgens are the key factors in either the initiation or progression of prostate cancer by inducing oxidative stress. In the present set of investigations, the antioxidative potential of Crataeva nurvala bark extract against androgen-mediated oxidative stress in male Wistar rats has been studied. Materials and Methods: Oxidative damage in prostate was induced in rats by the injection of testosterone (100 mg/kg body weight [bw] for 3 days followed by injection of chemical carcinogen N-Methyl N-Nitroso Urea (50 mg/kg bw for 1 week. The oxidative damage in prostate-induced rats were treated with the ethanolic extract of Crataeva nurvala bark (150 mg/kg bw and testosterone injection (2 mg/ kg bw was also continued through the experimental period of 4 months. The prostate tissue was dissected out for biochemical analysis of lipid peroxidation and enzymic-antioxidants viz. catalase, superoxide dismutase, glutathione peroxidase, glutathione-S-transferase, and glutathione reductase; the non-enzymic antioxidants viz. reduced glutathione, and Vitamin C. Results: The results revealed that testosterone administration induced the oxidative stress in rat prostate; however, in drug (150 mg/kg bw supplemented groups, a significant protective effect of Crataeva nurvala bark against testosterone-induced oxidative injury was recorded. Conclusion: Hence, the study reveals that constituents present in Crataeva nurvala bark impart protection against androgen-induced oxidative injury in prostate.

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

    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

    2009-09-01

    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

    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.

    The present study examined whether structural peculiarities in the brain-efferent pathway to the organ of Corti may underlie functional differences in hearing between pigmented and albino individuals of the same mammalian species. Pigmented Brown-Norway rats and albino Wistar rats received unilateral injections of an aqueous solution of the retrograde neuronal tracer Fluorogold (FG) into the scala tympani of the cochlea to identify olivocochlear neurons (OCN) in the brainstem superior olivary complex. After five days, brains were perfusion-fixed and brainstem sections were cut and analyzed with respect to retrogradely labeled neurons. Intrinsic neurons of the lateral system were located exclusively in the ipsilateral lateral superior olive (LSO) in both groups. Shell neurons surrounding the LSO and in periolivary regions, which made up only 5-8% of all OCN, were more often contralaterally located in albino than in pigmented animals. A striking difference was observed in the laterality of neurons of the medial olivocochlear (MOC) system, which provided more than one third of all OCN. These neurons, located in the rostral periolivary region and in the ventral nucleus of the trapezoid body, were observed contralateral to 45% in pigmented and to 68% in albino animals. Our study, the first to compare the origin of the olivocochlear bundle in pigmented and albino rats, provides evidence for differences in the crossing pattern of the olivocochlear pathway. These were found predominantly in the MOC system providing the direct efferent innervation of cochlear outer hair cells. Our findings may account for the alterations in auditory perception observed in albino mammals including man. PMID:26657095

    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...

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

    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

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

    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 (100μg/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 (100μg/rat) for 21 successive days, after one hour of the last dose of the treatment, a single dose of CCl4 (0.5 ml/kg body weight) was given. Then all animals were sacrificed, 24 hr post experimental design period for each group. Our results revealed that, fourteen compounds were identified by chromatography-mass spectrometry analysis (GC- MS analysis). Propolis ethanolic extract inhibited the growth of six from the tested microorganisms including bacteria and fungi at 5 mg/ml against E. coli and B. subtilis and 20 mg/ml against S. aureus, P. aeruginosa, Penicillium italicum and Candida albicans, while it has no effect on A. fumigatus and Syncephalstrum racemasum. In experimental animals, Leucocytic counts and platelets, in addition, AST, ALT, CK and LDH were significantly increased, meanwhile, triiodothyronine (T3) and thyroxine (T4) level was decreased in CCl4 treated rats (group 3) compared to the control (group 1). Protection with ethanolic extract of propolis to rats received CCl4 (group 4) ameliorated the

  5. Comparison of anti-inflammatory activity of nigella sativa and diclofenac sodium in albino rats

    Background: Nigella sativa or Kalonji is a naturally occurring plant in Pakistan and other countries which possesses a wide range of medicinal properties, the anti-inflammatory property being one of these. Diclofenac sodium is a commonly used anti-inflammatory drug. The purpose of this study was to compare the anti-inflammatory effect of ethanolic extract of Nigella sativa seeds with that of diclofenac sodium in albino rats. Method: This laboratory randomized controlled trial (RCT) was conducted in the Physiology Department, Services Institute of Medical Sciences (SIMS), Lahore. The study was carried out on 90 male albino rats. Five percent formalin in a dose of 50 meu 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. Increase in paw diameter, and total and differential leukocyte counts were measured as markers of inflammation. Results: Nigella sativa seeds extract caused significant (p<0.05) reduction in the paw inflammatory response in albino rats. The effect was longer in duration than the effect caused by diclofenac sodium; however, the extract was comparatively less potent than diclofenac sodium. The extract had no significant effect (p>0.05) on the total or differential leukocyte counts. Conclusion: Our results suggest that ethanolic extract of Nigella sativa seeds possesses potent anti-inflammatory effect, in albino rats however, this effect is comparatively less but prolonged than that produced by diclofenac sodium.

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

    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)

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

    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 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

  13. Oral toxicity of Madhuca butyracea Macb. saponins to albino rats.

    Lalitha, T; Vishwanatha, S; Venkataraman, L V

    1990-07-01

    Saponins, isolated from M. butyracea, were assessed for their acute and subacute oral toxicity in albino rats. Acute doses of saponins caused mortalities and LD50 and LD90 values were 330 and 430 mg/kg body wt respectively. Severe diarrhoea, restlessness and histopathological changes were observed in liver and kidney. Diets containing saponins at 0,250,500 and 1000 ppm for 14 weeks did not affect food intake, growth or organ weights, but induced mild histological changes in liver and kidney and altered the serum levels of alkaline phosphatase, blood urea nitrogen, cholesterol and proteins, particularly in female rats.

  14. Effect of noise stress on cardiovascular system in adult male albino rat: implication of stress hormones, endothelial dysfunction and oxidative stress.

    Said, Mona A; El-Gohary, Ola A

    2016-07-01

    Noise pollution has been realized as an environmental stressor associated with modern life style that affects our health without being consciously aware of it. The present study investigated the effect of acute, chronic intermittent and chronic continuous exposure to noise of intensity 80-100 dB on heart rate and mean systemic arterial blood pressure in rats and the possible underlying mechanisms. Noise stress causes significant increase in heart rate, mean systemic arterial blood pressure as well as significant increase in plasma levels of corticosterone, adrenaline, noradrenaline, endothelin-1, nitric oxide and malondialdehyde with significant decrease in superoxide dismutase and these values are significantly more worse in chronic continuous exposure to noise than acute or chronic intermittent exposure. These findings suggest that noise stress has many adverse effects on cardiovascular system via increasing plasma levels of stress hormones, oxidative stress and endothelial dysfunction. These findings have major implication in the management of adverse cardiovascular reactions of people subjected to daily noise stress. PMID:27174896

  15. Combined Effect of heat stress and radiation exposure on levels of testosterone lactate dehydrogenase, total lipids and cholesterol in blood plasma and testicular tissue of male albino rats

    Hyperthermia and radiotherapy are used as relatively successful modalities in the treatment of some diseases. This work aims to gain a better understanding about the testicular physiological changes caused by a combined stress of heat and gamma radiation. Rats were divided into four groups : 1.Control, 2.Irradiated at a dose level 6 Gy, 3.Exposed to heat tress for one, 3, 5 and 7 days and group 4 exposed to heat tress as group 3 followed by irradiation directly at the end of heat treatment. Plasma levels of testosterone, lactate dehydrogenase (LDH), total lipids and total cholesterol, as well as, testicular content of total lipids and total cholesterol were detected. Results showed that irradiation (6 Gy) induced significant decreases (P<0.001) in plasma testosterone level, whereas, it elevated significantly the plasma levels of LDH activity and total cholesterol. The heat stress caused significant declines in plasma testosterone , LDH (after 1, 3 and 5 days) and total lipids, but not testicular content of total lipids. Conversely, it increased the rectal temperature and both, plasma and testicular tissue content of total cholesterol levels. The whole-body gamma irradiation direcrly post heat stress intervals boosted the heat stress effect on all the examined parameters. Hence it could be concluded that exposure to whole-body gamma irradiation in high ambient temperatures diminished the testicular function by decreasing the sexual hormone testosterone although its precursor cholesterol increased in both plasma and testicular tissue. This combined treatment seemed to block the mechanism of testosterone formation in testicular tissue, and in turn, decresed its levels in plasma. Further investigations are needed to study such combined effect of heat stress andirradiation on the testicular potency and the testicular function

  16. Attenuation of the Disruptive Effect induced by the Insecticide Fenvalerate on Total Monoamine Content and Testosterone Level in Adult Male Albino Rats Using Salvia aegyptiaca Extract

    Administration of fenvalerate (90 mg/kg) to rats resulted in a significant decrease in dopamine (OA) content in most of brain areas under investigation. Its content in pons + medulla oblongata was the most affected recording - 62.98 %, on day 7, compared to control. Furthermore, norepinephrine (NE) content gradually decreased in different brain areas showing its maximal decrease in cerebellum with percentage change -64.89% on day 7. Serotonin (5-HT) and its metabolite 5-hydroxyindoleacetic acid (5-HIAA) showed maximal significant decrease, in the cortex with percentage differences -78.33 and -72.61%, respectively. Similarly, fen valerate resulted in a gradual decrease in serum testosterone level recording its maximal effect (-46. 58 %) at the end of the experimental period. On the other hand, administration of Salvia aegyptiaca (2 g/kg) caused a significant increase in monoamine contents (DA, NE, 5-HT and 5- HlAA) in most of the brain areas under investigation, throughout the experimental period. Moreover, Salvia extract administration resulted in a significant elevation in serum testosterone level, one day after administration, recording its maximal effect (55.75%) on day 7. Animals that received the combined treatment (Salvia extract one hour after fen valerate administration) showed that monoamine contents in most of the brain areas were more or less near to the control values. Furthermore, no significant change was noticed in serum testosterone level throughout the experiment in the combined treatment. From the present study, it can be concluded that Salvia aegyptiaca extract seems to be potentially promising for attenuating the disruption that occurred in monoamine and testosterone levels. This could highly recommend Salvia aegyptiaca to be a potential herb for further studies in the future for extracting compounds of medical use

  17. [Thoracic duct valves in man and albino rat].

    Petrenko, V M; Kruglov, S V

    2004-01-01

    The aim of this research was to determine the number, structure and position of valves along the whole length of thoracic duct in man and albino rat. The study was performed using the material obtained from 30 human corpses of men and women aged 17 to 60 years with no history of cardiovascular pathology and from 60 outbred albino rats of both sexes aged 5 to 12 months. Material was fixed in 10% neutral formalin. Anterior wall of thoracic duct was longitudinally dissected. Thoracic duct of 30 rats was stained with gallocyanin-chrome alum, in the remaining animals it was studied after its injection with blue Gerota's mass. In most cases, the valves consisted of two semilunar cusps. Thoracic duct was found to contain on the average 14.7+/-0.2 valves in man and 11.9+/-0.2 valves in rat. Most of all valves were found in the upper (anterior) 1/3 of the thoracic duct, least--in its middle part. This seems to be determined by anatomo-topographic features of the different parts of thoracic duct. PMID:15839250

    2013-12-01

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

    2015-09-01

    The present study was carried out to investigate the acute effect of aspartame on oxidative stress in the Wistar albino rat brain. We sought to investigate whether acute administration of aspartame (75 mg/kg) could release methanol and induce oxidative stress in the rat brain 24 hours after administration. To mimic human methanol metabolism, methotrexate treated rats were used to study aspartame effects. Wistar strain male albino rats were administered with aspartame orally as a single dose and studied along with controls and methotrexate treated controls. Blood methanol and formate level were estimated after 24 hours and rats were sacrificed and free radical changes were observed in discrete regions by assessing the scavenging enzymes, reduce dglutathione (GSH), lipid peroxidation and protein thiol levels. There was a significant increase in lipid peroxidation levels, superoxide dismutase activity (SOD), glutathione peroxidase levels (GPx), and catalase activity (CAT) with a significant decrease in GSH and protein thiol. Aspartame exposure resulted in detectable methanol even after 24 hours. Methanol and its metabolites may be responsible for the generation of oxidative stress in brain regions. The observed alteration in aspartame fed animals may be due to its metabolite methanol and elevated formate. The elevated free radicals due to methanol induced oxidative stress. PMID:26445572

    2011-01-01

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

    2012-09-01

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

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

    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

    Full Text Available Accumulative reports documented that oxidative stress is implicated in many human and animal diseases. However, the reports concerning the effect of oxidative stress on pregnancy outcome are limited and scarce. The objective of this study was to determine the impact of oxidative stress on pregnancy outcome and to assess the antioxidant effect of vitamin C and E on oxidative stress parameters in blood and placental tissue samples in experimental pregnant animals model exposed to oxidative stress. Wister Albino rats were used in this work to investigate the effects of oxidative stress exposure (addition of H2O2 to the drinking water on pregnancy outcome. Rats were divided into 5 groups, as follows: Group I (included 7 normal pregnant rats which served as control group. Group II (exposed to 1 % H2O2 included 7 pregnant rats, the rats were allowed to become pregnant and received (1% H2O2 in drinking water from day 7th till the day 19th of pregnancy. Group III (exposed to 3% H2O2 included 8 pregnant rats. Same as group 2, but the rats were exposed to a higher concentration of H2O2 (3% in drinking water. Group IV (included 8 pregnant rats. Pregnant rats received vitamins C and E without induction of oxidative stress. Group V (included 8 pregnant rats.induction of oxidative stress by 1% H2O2 with vitamins supplementation in the pregnant rats. Serum total antioxidants capacity (TAC, serum and placental tissue oxidative stress biomarker; 8-iso prostaglandin F2α (8-Isoprostane were measured using specific ELISA kits. Also placental tissues of pregnant rats were isolated and put directly in 10% formalin prepared for histopathological examination.

  7. Effect of Some Antioxidants on the Physical Fitness of Albino Rats

    In recent years, more attention has been paid for searching of natural antioxidants and their evaluation in either medicinal practice or as food raw materials. The aim of the present research is to assess the effect of several well-known products used as antioxidants, on body weight, haemopoesis, endocrine system and lipid profile in normal albino rats. Thirty male adult albino rats were equally arranged into 5 groups, the first group was served as control and the others received special treatments where taurine (2% in drinking water), tryptophan (100 mg/kg b.w. orally), hawthorn extract (50 mg/100 g b.w. orally) and coenzyme Q10 (50 mg/kg b.w. orally) were given for two months. Body weight was regularly recorded twice a week and at the end of the experiment, the rats were decapitated. Red blood cell count (RBCs), hemoglobin (Hb) content, reticulocytic count, white blood cell count (WBCs) and glutathione (GSH) concentration were estimated in blood, while, triiodothyronine (T3), thyroxin (T4), Testosterone, and corticosterone hormones besides lipid profile were estimated in the serum. The results denoted that although there is a slight improvement in the parameters tested, it does not deserve the coast of the regular use of these antioxidants and further investigations still needed

    Background and Objectives: Type 2 diabetes mellitus (DM) is a prevalent disorder. Diabetic keratopathy is a well-known ocular complication secondary to type 2 DM. Topical insulin application did not affect apoptosis and necrosis levels in corneal epithelium. Autologous cell transplantation is not a viable option for diabetic patients with bilateral limbal stem cell deficiency. The present study aimed at assessing the possible effect of hemopoeitic stem cell (HSC) therapy on induced diabetic keratopathy in albino rat. Methods and Results: Fifteen male albino rats were divided into control group of 2 rats, diabetic group of 8 rats receiving single intraperitoneal (IP) injection of 50 mg/kg streptozotocin (STZ). 3 animals were sacrificed 6 weeks following confirmation of diabetes to confirm keratopathy and 5 rats were sacrificed 4 weeks following confirmation of keratopathy. SC therapy group included 5 rats injected with HSCs 6 weeks following confirmation of diabetes and sacrificed 4 weeks following SC therapy. Cord blood collection, stem cells isolation and labeling were performed. Eye specimens were subjected to histological, histochemical, immunohistochemical, morphometric and statistical studies. In diabetic group, the central cornea showed multiple cells with vacuolated cytoplasm and dark nuclei, focal epithelial discontinuity, reduced corneal thickness and less number of layers of corneal and conjunctival epithelia. In stem cell therapy group, few cells with vacuolated cytoplasm and dark nuclei were found in the corneal and conjunctival epithelia with more number of epithelial layers. Conclusions: A definite ameliorating effect of HSC therapy was detected on diabetic keratopathy. The therapeutic cells were effective in limiting corneal epithelial changes. PMID:24298355

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

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

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

    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, α2- and β1-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, α1 and α2-globulins in both sexes; serotonin and β1-globulin in the male rats, total proteins and albumin in the females. It could be concluded that potato chips consumption might induce numerous adverse effects in various body organs

  1. Influence of pesticides on thyroid gland activity in male rats

    The plasma levels of T3, T4 and TSH were determined following daily administrations of 1/10 LD50 of metacide (organophoshosphorus) or methavine (carbamate or metoxuron (herbicide) pesticides in male albino rats for 45 days. At the end of the experiment, significant increase of body weights were observed in rats treated with metacide or metoxuron while methavine led to significant decreased TSH secretion. Metoxuron caused significant decrease in both T3 and T4 levels in plasma and metacide increased T3 and increased T4 levels in plasma of male rats

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

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

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

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

  10. Effect of Schizandra chinensis lignans on cell division in the corneal epithelium and tongue of albino rats exposed to chronic cold stress

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

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

  13. The acute lethal dose 50 (LD50) of caffeine in albino rats.

    Adamson, Richard H

    2016-10-01

    An acute LD50 is a statistically derived amount of a substance that can be expected to cause death in 50% of the animals when given by a specified route as a single dose and the animals observed for a specified time period. Although conducting routine acute toxicity testing in rodents has been criticized, it can serve useful functions and also have practical implications. Material safety data sheets (MSDS) will reflect the acute toxicity of a substance and may require workers to wear protective gear, if appropriate, based on the LD50. There is no information in the scientific published literature which calculates a mean LD50 and standard deviation for caffeine administered orally to rats, using studies performed under good laboratory practice (GLP) or equivalent. This report does that and should be useful to manufacturers, packagers, transporters and regulators of this material. Using data from studies that are reproducible and reliable, the most accurate estimate of the acute LD50 of caffeine administered orally in male albino rats is hereby reported to be 367/mg/kg.

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

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

    Pesticides are being used for plant protection to increase food protection and to reduce insect-borne diseases worldwide. Exposure to the pesticides may cause genotoxic effects on both the target and nontarget organisms, including man. Therefore, the mutagenicity evaluation of such pesticides has become a priority area of research. Imidacloprid (IMI), a neonicotinoid insecticide, is widely used in agriculture either alone or in combination with other insecticides. A combined approach employing micronucleus test (MNT) and chromosomal aberrations assay (CA) was utilized to assess the mutagenicity of imidacloprid in bone marrow of Swiss albino male mice. IMI suspension was prepared in 3% gum acacia and administered at doses of 5.5, 11 and 22 mg/kg body weight for 7, 14 and 28 days to mice. IMI treatment resulted in a dose and time-dependant increase in the frequencies of micronuclei per cell and chromosomal aberrations in bone marrow cells. A statistically significant increase in chromosomal aberrations and micronuclei/cell was found only after daily treatment of IMI at highest selected dose (22 mg/kg body weight) for longest selected time period (28 days) compared to the control group. Thus, daily exposure of imidacloprid at a dose level of 22 mg/kg body weight for 28 days caused mutagenic effects on the somatic cells of Swiss albino male mice. PMID:26823062

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

    Full Text Available 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.

    The issue of male germ line mutagenesis and the effects on developmental defects in the next generation has become increasingly high profile over recent years. Mutagenic substance affects germinal cells in the testis. Since the cells are undergoing different phases of cell division and maturation, it is an ideal system to study the effect of chemotherapeutic agents. There are lacunae in the literature on the effect of sorafenib on gonadal function. With background, a study was planned to evaluate the effects of sorafenib on sperm count and sperm motility in male Swiss albino mice. Male Swiss albino mice were used for the study. The animals were segregated into control, positive control (PC) and three treatment groups. PC received oral imatinib (100 mg/kg body weight) and treatment groups received 25, 50, and 100 mg/kg body weight of sorafenib orally for 7 consecutive days at intervals of 24 h between two administrations. The control group remained in the home cage for an equal duration of time to match their corresponding treatment groups. The animals were sacrificed at the end of 1st, 2nd, 4th, 5th, 7th, and 10th weeks after the last exposure to drug, respectively. Sperm suspensions were prepared and introduced into a counting chamber. Total sperm count and motility were recorded. There was a significant decrease in sperm count and sperm motility by sorafenib which was comparable with the effect of PC imatinib. Sorafenib adversely affects sperm count and sperm motility which are reversible after discontinuation of treatment. PMID:26605157

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

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

  1. Harmful effect of protein difficiency on lipids, glucose, insulin and estradiol levels in female albino rats

    The present study was undertaken to investigate the harmful effect of protein deficient diet on some biochemical activities in serum of female rats. Protein malnutrition is a well known socioeconomic problem in different parts of the world. Many studies were investigated on the biological parameters following protein malnutrition in human and experimental animals. Forty albino female rats were divided into 3 groups. The first group (10 rats) fed 18% protein diet and served as normal control and the other two groups, each contains 15 rats, fed 5% protein for 21 and 45 days, respectively, and served as malnourished groups. The results showed significant decrease in total body weight, serum glucose, insulin and estradiol levels in the third group as well as decrease in the total cholesterol, HDL-cholesterol, LDL-cholesterol and VLDL-cholesterol and triglycerides concentrations that compared to normal control rats

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

    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 β-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 β-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 β-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 β-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 β-carotene before irradiation causes significant increase in alkaline phosphatase, glutathione and glutathione peroxidase activity and significant decrease in acid phosphatase activity compared to the irradiated group. The results of the present study indicated that β-carotene ameliorated oxidative stress and the loss of cellular antioxidants and suggest that β-carotene may reduce the radiation damage in testis of male albino rats

    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.

    Full Text Available Background and aim of the study- Diabetes is a chronic metabolic disease which affects large number of population all over the world. More than 400 traditional medicinal plants have been recorded for helping in controlling such disease. This study investigated effects of some plants used in Saudi Arabia and some other Arab countries as antidiabetic agents. Materials and Methods: One hundred fifty adult male Albino rats were divided into six experimental groups each consist of twenty five rats. The first group was considered as a control group. The rest of groups were affected by induction of experimental diabetes by subcutaneous injection of Alloxan. The second group consisted of diabetic rats without any treatment. The third group was treated by the aqueous extract of mixture contains Foenugreek, Nigella and Termis seeds. The fourth group was treated with the aqueous extract of Nigella sativa seeds, while the fifth group was treated with the aqueous extract of Foenugreek seeds.The sixth one was treated with the aqueous extract of Termis seeds with the administered dose of the plant extracts (100 mg/kg body weight.After four weeks of treatment, different biochemical parameters were performed including estimation of blood sugar level and serum insulin level. Pancreatic and liver samples were obtained and processed for microscopic and quantitative evaluation after staining the prepared sections with both heamatoxylin and eosin as well as a special stain for demonstration of the different pancreatic cells in the Islet of Langerhans. Results: The usage of the mixture or each plant alone corrected the glucose level and insulin level. Microscopically there was definite decrease in the number and diameter of beta pancreatic cells in the diabetic group, while the other pancreatic cells were not affected (alpha and delta cells. The use of medicinal plants in the different groups of this study greatly improved such cellular changes and the level of blood

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

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

    2009-01-01

    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

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

    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

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

  13. Modulation Of Acrylamide-Induced Biochemical Alterations In Albino Rats

    Acrylamide (ACR) is an industrial neurotoxic chemical that has been recently found in carbohydrate rich foods cooked at high temperature. The objective of the current study is to evaluate the protective effects of rosemary extract against ACR-induced toxicity in rats. The experimental rats were divided into four groups included a control group, a group treated orally with rosemary extract by supercritical fluid extractor (150 mg/kg/day) for 14 days, a group treated orally with ACR (50 mg/kg/day) for 14 days and a group treated orally with rosemary extract + acrylamide for 14 days. The results indicated that treatment with ACR alone resulted in a significant decrease in the haematological parameters, triglycerides, insulin, creatine kinase and choline esterase while the concentrations of urea, creatinine, ALT, AST and alkaline phosphatase were increased. Treatment with rosemary extract during ACR treatment reduced the effects induced by ACR. It could be concluded that rosemary extract exhibited a protective action against ACR-induced biochemical alterations in rats. For this reason, rosemary is recommended to be used in cooked food due to its palatable taste and prophylactic effect.

    2015-06-01

    Full Text Available Background: Caverta (Sildenafil citrate, an oral therapy for Erectile Dysfunction (ED, being the citrate salt of Sildenafil, is a selective inhibitor of cGMP- specific phosphodiestrase type (PDE5. Aim: To study the drug- induced (i changes in the trace element content of Testis and (ii changes in the histoarchitecture of Testis of the experimental Albino rats. Materials and Methods: For the present study, totally 48 animals were selected on weight basis and divided into 8 groups (S1, S2, S3, S4, S5, S6, S7 and S8 with six animals in each group. Control animals (S1 were fed with conductivity water while the experimental animals (S2, S3, S4 and S5 were treated with a single dose of Caverta (@ 1µg/g body weight. Control animals were sacrificed at zero hour while the experimental animals (S2, S3, S4 and S5 were sacrificed after 1 hour, 2½ hours, 4 hours and 24 hours of drug administration respectively S6, S7 and S8 group of animals were fed with a single dose of the chosen drug (@ 1µg/g body weight daily for all the 15, 30 and 45 days respectively. These animals were sacrificed after 4 hours of the last dosage. Vertical ventral midline incision was made in the abdominal wall to collect the left and right Testes. Results: The spectral analysis indicates that the long term Caverta treatment of Albino rats results in the accumulation of Iron and Copper levels accompanied by a depletion of Nickel levels in the Testis. The histological studies indicate that long term exposure of Testis to Caverta leads to distorted histoarchitecture of the seminiferous tubules, interstitial space dilation and separation of Spermatogenic cells. Conclusion: Long term Sildenafil Citrate (Caverta treatment of Albino rats will bring in adverse effects and will completely alter the histoarchitecture of the Testis.

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

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

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

    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.)

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

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

    Objective: In the present study, an attempt has been made to investigate the effect of ethanolic seed extract of Caesalpinia bonducella (C. bonducella) on fertility in female Wistar albino rats. Methods: Pregnant rats were randomized into two groups containing eight animals in each group. Control group rats were orally administered with 1 mL/100 g b.wt of distilled water while rats in second group received 300 mg/kg of the seed extract from gestation day 1-7, once daily. The animals were sacrificed twenty four hours after the last dose on gestation day 12. Results:A significant reduction in implantation index and a contrasting significant increase in resorption index, pre-implantation and post-implantation loss was recorded in the seed extract treated rats. Progesterone level declined significantly in rats treated with seed extract. Ovary revealed degenerated corpora lutea in treated rats. The embryos were noticed with craniofacial deformities in extract treated group. Conclusions: The results obtained in this study suggest that the seeds of C. bonducella possess antifertility activity probably due to its antiprogesterogenic hormonal properties that can modulate the reproductive function of the experimental rats.

    Objective:To evaluate the ameliorative role of grapefruit juice on the cytogenetic and testicular damage induced by the antiarrythmic drug amiodarone in albino rats. Methods: Animals were divided into four groups. Group I was considered as control. Group II was given grapefruit juice at a dose level of 27 mL/kg body weight. Group III was orally administered amiodarone (18 mg/kg body weight) daily for 5 weeks. Animals were sacrificed after 5 weeks of treatment. Bone marrow was collected from the femurs for analysis of chromosomal aberrations and mitotic indices. Testes were removed and stained with H&E for histological examination. Sperms were collected from epidedymis for detection of sperm head abnormalities. Comet assay was used to detect DNA damage. Results: Amiodarone treatment caused a significant increase in the percentage of chromosomal aberrations, decreased the mitotic index and increased DNA damage. The testis showed many histopathological alterations, inhibition of spermatogenesis and morphometric changes. The number of sperm head abnormalities was increased. Treating animals with amiodarone and grapefruit juice caused a reduction in chromosomal aberrations, mitotic index, DNA damage and testicular alterations caused by amiodarone. Conclusions:The results of this study indicated that grapefruit juice ameliorates the cytotoxicty and testicular alterations induced by amiodarone in albino rats and this is may be due to the potent antioxidant effects of its components.

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

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

    Full Text Available Aim: Despite having better tolerability and a wide range of clinical applications over other antidepressants, selective serotonin reuptake inhibitors (SSRIs are also known to be associated with serious adverse effects like suicidal ideation on chronic use. The present study had explored the impact of the chronic use of sertraline, an SSRI, on the behavioral changes in Wistar albino rats. Materials and Methods: The study was conducted on 30 Wistar albino rats of either sex; divided into five groups. Four groups were subjected to chronic mild stress induced by using various stressors randomly scheduled in a week and continued for a period of 3 weeks. The stressed rodents were subjected to sertraline treatment for 9 weeks in different human therapeutic doses extrapolated to animal doses. Behavioral changes were monitored, assessed, and evaluated throughout the treatment phase with the help of tests such as locomotor activity test, forced swim test, tail suspension test, antianxiety test, and sucrose preference test (SPT. Results: All tests except SPT, demonstrated significant (P < 0.05 reduction in depressive-like activity in the stressed rodents by the mid-treatment phase, followed by an abrupt onset of the depressive state by the end of the treatment phase. SPT showed a significant (P < 0.05 increase in sucrose consumption throughout the treatment phase. Conclusion: Behavioral changes following chronic sertraline administration conferred gradual remission of depression state on initial treatment phase, followed by a reversal of effect on chronic use.

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

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

    Full Text Available 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

    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

    Objective: To evaluate the hazardous effects of fried potato chips upon the retina of two developmental stages of the albino rats aged 7 and 14 days from parturition. Methods: Pregnant rats were arranged into two groups: control pregnant rats and consequently their delivered newborns until reaching 7 and 14 days old from parturition and fried potato chips group in which pregnant rats at the 6th day of gestation maintained on diet formed of fried potato chips supplied from the market mixed with standard diet at a concentration of 50% per each till 7 and 14 post-partum. Three fold integrated approaches were adopted, namely, histological, ultrastructural and proteomic analysis. Results: Histological examination of the retina of the experimental offsprings revealed many histopathological changes, including massive degeneration, vacuolization and cell loss in the ganglion cell layer, as well as general reduction in retinal size. At the ultrastructural level, the retina of experimental offsprings exhibited number of deformities, including ill differentiated and degenerated nuclear layer, malformed and vacuolated pigment epithelium with vesiculated and fragmented rough endoplasmic reticulum, degenerated outer segment of photoreceptors, as well as swollen choriocapillaris and loss of neuronal cells. Proteomic analysis of retina of the two experimental developmental stages showed variations in the expressed proteins as a result of intoxication which illustrated the adverse toxic effects of fried potato chips upon the retina. Conclusions: It can be concluded that the effect of fried potato chips on the development of retina in rats may be due to the presence of acrylamide or its metabolite.

    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

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

    Provitamin D, cholecalciferol, undergoes hydroxylation at the 25 and the 1α 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 1α 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, 1α hydroxyvitamin D3 treated group (G 3) received a total dose of 5 ng/g body weight of 1α hydroxyvitamin D3 dissolved in propyl alcohol divided into six doses each given twice weekly for three weeks via the subcutaneous route, and CCl4 + 1α hydroxyvitamin D3 treated group (G 4) received the same dose of CCl4 and 1α hydroxyvitamin D3 concomitantly as previously described. Liver tissues from sacrificed animals were fixed in 10% formalin before sectioning and stained with eosin and hematoxyline then were examined histopathologically. Sera from control and treated animals were separated from blood and examined for ALT, AST, alkaline phosphatase and LDH levels. Serum total protein, albumin, globulin, A/G, bilirubin, creatinine, phosphorous and Ca levels were also monitored. Data from the present study showed that administration of 1α 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 1α hydroxyvitamin D3 compound

    The effect of Gomutra ark (GoA) on experimental alloxan-induced diabetes in rats was studied. For this purpose, Wistar albino rats of either sex weighing 200-250 g were used. The biochemical parameters like blood sugar, vitamin C, and malondialdehyde release were measured. The safety profile of GoA was evaluated using acute and chronic toxicity studies. GoA significantly lowers blood glucose in diabetic rats although the observed effect was found to be less than glibenclamide. It significantly lowers the level of malondialdehyde and vitamin C in diabetic rats. No toxicity was observed even when cow urine was given 32 times of the study dose in acute toxicity and no significant changes were seen when it was used chronically, which suggests that cow urine is having a very high therapeutic index. This study supports the traditional use of GoA in diabetes and is having a high therapeutic index and is safe for chronic use. However, further studies are needed to elucidate the mechanism of action of Gomutra ark. PMID:23284212
