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

International Nuclear Information System (INIS)

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

Ameliorative effect Trichosanthes dioica root against experimentally induced arsenic toxicity in male albino rats.  

Science.gov (United States)

The present study evaluated the ameliorative potential of hydroalcoholic extract of Trichosanthes dioica root (TDA) against arsenic induced toxicity in male albino rats. TDA (5 and 10mg/kg) was administered orally to rats for 20 consecutive days before oral administration of sodium arsenite (10mg/kg) for 8 days. Then the body weights, organ weights, haematological profiles, serum biochemical profile; hepatic and renal antioxidative parameters viz. lipid peroxidation, reduced and oxidized glutathione, glutathione-S-transferase, glutathione peroxidase, glutathione reductase, superoxide dismutase, catalase and DNA fragmentation were evaluated. Pretreatment with TDA markedly and significantly normalized body weights, organ weights, haematological profiles, serum biochemical profile and significantly modulated all the hepatic and renal biochemical parameters and reduced DNA fragmentation in arsenic intoxicated rats. The present findings conclude that T. dioica root possessed remarkable ameliorative effect against arsenic induced organ toxicity in male albino rats mediated by alleviation of arsenic induced oxidative stress by multiple mechanisms.

International Nuclear Information System (INIS)

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

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

Science.gov (United States)

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

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

International Nuclear Information System (INIS)

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

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

International Nuclear Information System (INIS)

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

Antifertility investigations on the crude chloroform extract of Carica papaya Linn. seeds in male albino rats.  

Science.gov (United States)

Crude chloroform extract of C. papaya seeds (5 mg/animal/day, po, for 20, 40 and 60 days) was investigated for contraceptive efficacy and related side effects in male albino rats. The crude extract reduced fertility to zero per cent by 40 to 60 days of treatment. Suppression of cauda epididymal sperm motility was the most pronounced effect of the drug administration. Scanning electron microscopic observations revealed treatment induced abnormalities in sperms. Cauda epididymal and testicular sperm counts decreased following treatment. Clinical parameters did not show any alterations. Results suggest that the contraceptive effects of chloroform extract of papaya seeds are mainly post-testicular in nature without influencing toxicological profile and libido of the animals.

Antioxidant effect of beta-carotene on hypoxia induced oxidative stress in male albino rats.  

Science.gov (United States)

Hypoxia is known to induce oxidative stress in organisms leading to tissue injury. In the present study beta-carotene (BC) given at 10 mg/kg body weight (BW) in reducing the oxidative stress induced by hypoxia was evaluated on male albino rats. Hypoxia exposure caused an increase in malondialdehyde (MDA) levels in plasma and tissues, a concurrent decrease in blood glutathione (GSH), glutathione peroxidase (GPx), plasma protein and plasma BC content. Hemoglobin concentration, Red blood corpuscles (RBC) and White blood corpuscles (WBC) count were also increased under hypoxia. BC supplementation reversed the trend, inducing a significant decrease (P<0.05) in MDA and subsequent increase in plasma and tissue GSH levels in animals exposed to hypoxia. Blood GPx and plasma protein also increased significantly in BC supplemented animals. BC supplementation did not alter the changes in Hb concentration, RBC and WBC count. BC has potent antioxidant activities in reducing the oxidative stress induced by hypobaric hypoxia. PMID:11801375

Directory of Open Access Journals (Sweden)

Full Text Available In the current study, thirty adult male albino rats were used to investigate the effect of Ferula assafoetida on carbohydrate metabolism in alloxan-induced diabetes. Rats were divided into three equal groups, control, diabetic non treated and diabetic Ferula assafoetida treated groups. After thirty days of treatment five rats of each group were sacrificed and the others were left without any additional treatment for another 15 days (recovery period then were sacrificed. Body weight, blood glucose, serum insulin and liver glycogen content levels were determined for each rat at the end of each period. It was noticed that Ferula assafoetida treatment led to a significant improve in hyperglycemia, hypoinsulinemia, decreased liver glycogen and increased percentage of body weight change caused by alloxan. And this improvement was also seen after the recovery period. Ferula assafoetida treatment led also to marked improvement in the histopathological degenerative changes in the cells of islets of Langerhans caused by alloxan after both the treated and recovery periods.

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

International Nuclear Information System (INIS)

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.

Enhancement of the Role of Mixed Hypo lipotropic Agents in Male Albino Rats  

International Nuclear Information System (INIS)

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

Directory of Open Access Journals (Sweden)

Full Text Available

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

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

Directory of Open Access Journals (Sweden)

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

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

International Nuclear Information System (INIS)

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

Diuretic activity of leaves of Plectranthus amboinicus (Lour) Spreng in male albino rats.  

Science.gov (United States)

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

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

Directory of Open Access Journals (Sweden)

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

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

Directory of Open Access Journals (Sweden)

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

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

Directory of Open Access Journals (Sweden)

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

Fertility suppression in male albino rats by administration of methanolic extract of Opuntia dillenii.  

Science.gov (United States)

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

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

International Nuclear Information System (INIS)

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

Effect of Carica papaya bark extract on oxidative stress parameters in testes of male albino rats  

Directory of Open Access Journals (Sweden)

Full Text Available Summary: Carica papaya bark has contraceptive benefits when given at a high dose in male rats the mechanism at which it achieves this is yet to be fully understood. Forty male Wistar rats were used for the study. They were randomized into 8 groups Ia, IIa, IIIa, Ib, IIb, IIIb, IV and V respectively (n=5. Groups Ia-IIIa and Ib-IIIb were treated for 4 and 8 weeks with Carica papaya bark extract at doses 50 and 100 mg ml-1day-1 comparing to 2-5 ml distilled water baseline control. Group IV rats were observed for reversibility treated with alternating bark extract and distilled water for 16 weeks (8 weeks each. They were compared to Group V treated with distilled water alone for similar duration. The rats were sacrificed under chloroform anesthesia. The estimated parameters were testes volumes biochemical activities of testicular antioxidant enzymes and non-enzymes [superoxide dismutase (SOD, catalase (CAT, reduced glutathione (GSH and malondialdehyde (MDA] as well as total protein (TP. The extract treated groups (Groups Ia, IIa, Ib & IIb showed a decrease in TP and testicular volume. Also in these groups were significant increases in testicular MDA levels compared to control (Groups IIIa & IIIb. At both durations for the two doses, the extract resulted in a significant decrease in antioxidant enzymes. Animals in the reversibility study group showed values similar to baseline control. In conclusion, Carica papaya leaf extract essentially perturbed the testicular oxidative system this may be responsible for the contraceptive effect seen. Industrial relevance: The contraceptive benefits of aqueous extract of Carica papaya bark in orally treated male rats had been confirmed. This present study was tailored at reviewing variations in the gonadal proteins and stressors index in male rats administered established contraceptive doses of the extract. This would be helpful to industries intending to develop this herbal preparation as a contraceptive adjunct because it provides base line biochemical information on the testes that explains the likely possible mechanism of action of the herb.

Directory of Open Access Journals (Sweden)

Full Text Available Summary: The present study was conducted to investigate the antifertility activity of the ethanol root bark extract of Chrysophyllum albidum on sperm parameter and hormonal levels in rats. Eighteen male rats were divided into three groups of six animals each. The first group (A received distilled water and served as control. The second and third group (B & C of animals were administered the ethanol root bark extract daily at 100mg/kg body weight and 200mg/kg decrease in the caudal epididymal sperm count, motility and sperm morphology was observed compared with the control. Serum gonadotrophins and testosterone were measured and C. albidum extract also caused a dose related significant reduction (p<0.05 of serum testosterone, Luteinizing hormones and FSH concentrations in all treatment groups as compared to the control. The result showed that ethanol extract of the root bark of C. albidum suppresses the hormonal levels and sperm production in rats and deserves to be further investigated as a potential male contraceptive agent. Industrial relevance: The unique advantages of this antifertility option is that they are safer, reliable, affordable, long-lasting, acceptable and can be taken without consulting a health worker in comparison to pharmaceutical drugs that are expensive and have negative side effect.

International Nuclear Information System (INIS)

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

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

International Nuclear Information System (INIS)

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

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

International Nuclear Information System (INIS)

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

Quinalphos induced oxidative stress and histoarcheitectural alterations in adult male albino rats.  

Science.gov (United States)

Quinalphos is a synthetic organophosphate used as a broad spectrum insecticide and acaricide. The present study investigates the effect of three sub-lethal doses (0.52, 1.04, 2.6 mg/kg b.wt) of quinalphos for variable durations (15, 30 and 90 days) on oxidative stress and histopathological changes in adult male rats. Quinalphos treatment for 15 and 30 days resulted in a dose dependent significant increase in malondialdehyde (MDA) levels and glutathione-S-transferase (GST) activity together with a concurrent decrease in ferric reducing ability of plasma (FRAP) and glutathione (GSH) content. Quinalphos treatment for 90 days also induced a significant increase in MDA levels and GST activity but the effect was not dose-dependent. Histopathological examination of liver revealed architectural disarray and dilatation of sinusoids, focal fatty changes, accumulation of eosinophils and single cell necrosis with increasing doses. However, spleen and kidney did not show any histological changes. Administration of quinalphos resulted in oxidative stress and free radical induced injury as evidenced by increased lipid peroxidation, decreased FRAP and histopathological changes in liver.

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

Directory of Open Access Journals (Sweden)

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

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

International Nuclear Information System (INIS)

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

Effect of Bifendate (DDB On Normal and Diseased Liver of Adult Male Albino Rats: An Experimental Study.  

Directory of Open Access Journals (Sweden)

Full Text Available Background: Fructus Schizandrae Sinensis bail, a traditional Chinese medicine, has been shown to lower the elevated serum level of liver enzymes of patients suffering from chronic active hepatitis. A synthetic derivative compound of Schisandrian, Dimethyl Diphenyl Bicarboxylate (DDB is now used widely in clinical fields as a hepatoprotective drug. Thus it is important to know whether DDB has a beneficial effect on damaged liver or not. Objective: To evaluate the protective effect of DDB on induced liver tissue injury in rats. Design: Experimental study. Setting: National Hepatology and Tropical Medicine Research Institute. The study was conducted from October (2004 to February (2005. Materials and methods: 120 male albino rats aged 6-8 weeks, weight 150-200g were grouped in six groups, 20 rats per group. Group 1 received food and water only, group 2 received food, water and DDB intragastric 6mg/kg daily for 12 weeks, group 3 received 20% ethanol instead of water, group 4 received 20% ethanol instead of water plus DDB, group 5 received thioacetamide (TAA in a dose of 200mg/kg body weight intraperitoneal injection, group 6 received thioacetamide plus DDB at the same dose of the above group. At the end of the trial, blood samples were taken from all groups for biochemical analysis. Liver tissue excised from each rat was fixed in 10% neutral formalin, embedded in paraffin, and stained with Hematoxylin and Eosin, as well as Masson's trichome stain, for evaluation of hepatic injury and/or fibrosis. Results: Statistical elevation of serum hepatic enzymes was noticed in rats received alcohol, Thioacetamide and alcohol + DDB (groups III, V and IV respectively compared to the corresponding control (P= 0.000. On the other hand, administration of DDB to TAA treated group (group VI induced significant improvement of liver function tests compared to other groups (P= 0.000. Histopathologically, the control livers showed normal lobular architecture without any pathological changes. Liver sections of animals administered alcohol, TAA respectively showed chronic inflammatory reaction, fat accumulation, hepatic parenchymal necrosis and/or hepatic fibrosis. Administration of DDB resulted in improvement of the pathological changes induced by TAA (group VI, but not that induced by alcohol (group IV. Conclusion: Our results revealed that DDB has antitoxic effect against TAA and ameliorates the dangerous effect on the liver parenchyma, while it has no beneficial effect on alcoholic liver disease.

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

International Nuclear Information System (INIS)

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

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

International Nuclear Information System (INIS)

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

Induction of epoxide hydrolase, glucuronosyl transferase, and sulfotransferase by phenethyl isothiocyanate in male Wistar albino rats.  

Science.gov (United States)

Phenethyl isothiocyanate (PEITC) is an isothiocyanate found in watercress as the glucosinolate (gluconasturtiin). The isothiocyanate is converted from the glucosinolate by intestinal microflora or when contacted with myrosinase during the chopping and mastication of the vegetable. PEITC manifested protection against chemically-induced cancers in various tissues. A potential mechanism of chemoprevention is by modulating the metabolism of carcinogens so as to promote deactivation. The principal objective of this study was to investigate in rats the effect of PEITC on carcinogen-metabolising enzyme systems such as sulfotransferase (SULT), N-acetyltransferase (NAT), glucuronosyl transferase (UDP), and epoxide hydrolase (EH) following exposure to low doses that simulate human dietary intake. Rats were fed for 2 weeks diets supplemented with PEITC at 0.06?µmol/g (low dose, i.e., dietary intake), 0.6?µmol/g (medium dose), and 6.0?µmol/g (high dose), and the enzymes were monitored in rat liver. At the Low dose, no induction of the SULT, NAT, and EH was noted, whereas UDP level was elevated. At the Medium dose, only SULT level was increased, whereas at the High dose marked increase in EH level was observed. It is concluded that PEITC modulates carcinogen-metabolising enzyme systems at doses reflecting human intake thus elucidating the mechanism of its chemoprevention. PMID:24592387

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

International Nuclear Information System (INIS)

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

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

Directory of Open Access Journals (Sweden)

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

Differential effects of alprazolam and clonazepam on the immune system and blood vessels of non-stressed and stressed adult male albino rats.  

Science.gov (United States)

Benzodiazepines belongs to one of the most commonly used anxiolytic and anticonvulsant drugs in the world. Full description of toxic effects on different organs is lacking for nearly all the current benzodiazepines. The aim of the current work was to study the immunologic and vascular changes induced by sub-chronic administration of alprazolam and clonazepam in non-stressed and stressed adult male albino rats. Forty-two adult male albino rats were divided into 6 groups (I): (Ia) Negative control rats, (Ib): Positive control rats received distilled water, (II): Stressed rats, (III): Non-stressed rats received daily oral dose of clonazepam (0.5 mg/kg), (IV): Stressed rats received daily oral dose of clonazepam (0.5 mg/kg), (V): Non-stressed rats received daily oral dose of alprazolam (0.3 mg/kg). (VI): Stressed rats received daily oral dose of alprazolam (0.3 mg/kg). At the end of the 4th week, total leukocyte count (WBCs) and differential count were determined, anti-sheep RBC antibody (Anti-SRBC) titer and interleukin-2 (IL-2) level were assessed, thymus glands, lymph nodes, spleens and abdominal aortae were submitted to histopathological examination. Alprazolam was found to induce a significant increase in neutrophil count and a significant decrease in lymphocytes, anti-SRBC titer and IL-2 level with severe depletion of the splenic, thymal and nodal lymphocytes, accompanied by congestion and eosinophilic vasculitis of all organs tested in comparison to clonazepam treated rats. Stress enhanced the toxic effects. It was concluded that the immune system and blood vessels can be adversely affected to a greater extent by short-term chronic administration of alprazolam than by clonazepam, and these toxic effects are aggravated by stress.

Differential effects of alprazolam and clonazepam on the immune system and blood vessels of non-stressed and stressed adult male albino rats  

Science.gov (United States)

Benzodiazepines belongs to one of the most commonly used anxiolytic and anticonvulsant drugs in the world. Full description of toxic effects on different organs is lacking for nearly all the current benzodiazepines. The aim of the current work was to study the immunologic and vascular changes induced by sub-chronic administration of alprazolam and clonazepam in non-stressed and stressed adult male albino rats. Forty-two adult male albino rats were divided into 6 groups (I): (Ia) Negative control rats, (Ib): Positive control rats received distilled water, (II): Stressed rats, (III): Non-stressed rats received daily oral dose of clonazepam (0.5 mg/kg), (IV): Stressed rats received daily oral dose of clonazepam (0.5 mg/kg), (V): Non-stressed rats received daily oral dose of alprazolam (0.3 mg/kg). (VI): Stressed rats received daily oral dose of alprazolam (0.3 mg/kg). At the end of the 4th week, total leukocyte count (WBCs) and differential count were determined, anti-sheep RBC antibody (Anti-SRBC) titer and interleukin-2 (IL-2) level were assessed, thymus glands, lymph nodes, spleens and abdominal aortae were submitted to histopathological examination. Alprazolam was found to induce a significant increase in neutrophil count and a significant decrease in lymphocytes, anti-SRBC titer and IL-2 level with severe depletion of the splenic, thymal and nodal lymphocytes, accompanied by congestion and eosinophilic vasculitis of all organs tested in comparison to clonazepam treated rats.

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

International Nuclear Information System (INIS)

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

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

International Nuclear Information System (INIS)

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

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

International Nuclear Information System (INIS)

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

Effect of caricapryl-99 seed alkaloid extract on the serum levels of sex hormones and pituitary gonadotrophins in male albino rats.  

Science.gov (United States)

Activity of alkaloid extract of caricapryl-99 seeds [Carica papaya Linn seeds] on the serum levels of steroid hormones was studied in adult male albino rats. Three tolerated doses obtained from the graph of percentage toxicity [10, 50 and 150 mg/kg] were separately administered orally, daily for three days to three groups of male rats [n=5] while group four of 5 rats received the vehicle [corn oil] as control. The results showed that 10 mg/kg/d caused increase serum levels of FSH and estrogen but decrease in the serum levels of LH and testosterone compared to control; 50 mg/kg/d elevated the serum levels of FSH, estrogen but inhibited testosterone; while 150 mg/kg/d pretreatments caused a significant decrease [p<0.01] in the serum levels of FSH, LH and testosterone. The results suggest that caricapryl-99 treatment inhibited the serum level of the androgen, testosterone which might result in a male infertility. PMID:19826459

Safety Evaluation of Long Term Treatment of Methanol Sub-Fraction of Seeds of Carica papaya as a Male Contraceptive with Particular Emphasis on Carcinogenicity in Albino Rats  

Directory of Open Access Journals (Sweden)

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

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

Directory of Open Access Journals (Sweden)

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

Effect of furostanol glycosides from Trigonella foenum-graecum on the reproductive system of male albino rats.  

Science.gov (United States)

Trigonella foenum (TF) has long been used in the traditional Indian systems of medicine for the treatment of various ailments. The objective was to study the anabolic and androgenic activity of the furostanol glycosides fraction of Trigonella foenum-graecum (Fenu-FG) in immature castrated male Wistar rats. It was also aimed to investigate the effect of Fenu-FG on testicular histology in non-castrated immature rats. The animals (55 ± 5 g) were castrated. The rats were treated with either vehicle, testosterone (10 mg/kg s.c. bi-weekly) or Fenu-FG (10 and 35 mg/kg p.o.) once daily for 4 weeks. At the end of the study, blood was withdrawn, serum testosterone and BUN were measured. Animals were killed and reproductive organs were excised and weighed.Fenu-FG (35 mg/kg p.o.) and testosterone (10 mg/kg, s.c. biweekly) increased the weight of the levator ani muscle as well as body weight. Fenu-FG (10 or 35 mg/kg p.o.) did not change the testosterone level in castrated rats. Histopathological examination of the testis of non-castrated rats treated with Fenu-FG (10, 35 mg/kg p.o.) showed normal architecture of the testis. Fenu-FG (35?mg/kg p.o.) showed anabolic activity without androgenic activity. PMID:20878698

Role of alpha-tocopherol on antioxidant status in liver, lung and kidney of PCB exposed male albino rats.  

Science.gov (United States)

Polychlorinated biphenyls (PCB) are widespread, lipophilic environmental pollutants which have been identified as contaminants in almost every component of the global ecosystem including fish, wildlife, and human adipose tissue, breast milk, and serum. Several studies have shown that PCBs can cause oxidative damage to biomolecules, in the form of lipid peroxidation, modulation of antioxidant enzymes, and oxidative stress. In the present study, we have sought to investigate the effects of alpha-tocopherol (vitamin E) on antioxidant status of PCB-induced toxicity in male Wistar rats. The protective effect of alpha-tocopherol (50mg/kg body weight/day) was tested in PCB-induced toxicity in rat liver, lung, and kidney. We report here that the oral supplementation of alpha-tocopherol was found to maintain the cellular redox status by maintaining the activities of superoxide dismutase, catalase, glutathione peroxidase, glutathione reductase accompanied with glutathione and vitamin E levels and down regulation in the levels of lipid peroxides, hydroxyl radical and hydrogen peroxides generation in PCB treated rats. Therefore, our present study demonstrates the PCB-induced deficits in antioxidant enzyme activities and increase in reactive oxygen species and lipid peroxidation levels in liver, kidney, and lung which can be overcome through simultaneous supplementation with alpha-tocopherol.

Role of zinc in regulating the testicular function. Part 1. Effect of dietary zinc deficiency on serum levels of gonadotropins, prolactin and testosterone in male albino rats.  

Science.gov (United States)

Hypogonadism is a major manifestation of zinc deficiency in both humans and animals. In this study, we try to elucidate the main role of zinc in regulating the testicular function. Ninety male weanling albino rats were divided into three groups: control, zinc-deficient (ZD), and zinc-supplemented (ZS) groups. Six rats from each group were sacrificed every two weeks over a total period of ten weeks. Serum levels of follicle-stimulating hormone (FSH), luteinizing hormone (LH), prolactin (PRL) and testosterone (T) were estimated by radioimmunoassay technique. Serum zinc concentrations were also determined. Data revealed that serum zinc concentrations were significantly low in ZD group compared to both control and ZS groups. Normal FSH and LH but low PRL and T levels were demonstrated in sera of ZD group compared to both control and ZS groups. We came to the following conclusions: zinc deficiency has no effect on the pituitary gonadotropin output. Zinc deficiency affects the testicular function either directly through its effect on the testicular steroidogenesis and/or indirectly through its effect on the pituitary synthesis and/or secretion of PRL.

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

International Nuclear Information System (INIS)

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

Material & Methods Thirty five male rats were used in the present study. They were allocated into five groups. The first group (5months old served as control group and the other remaining groups are (18 months old. The second group 1 ml/kg b.w. corn oil intramuscular injection through a period of two weeks .The third group received 2mg/kg b.w. of melatonin hormone orally daily for two weeks. 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 the thyroid functions and on the testicular structure. On the other hand, amelioration in T3 &T4 serum level was found in anti-aging treated rats compared with untreated aged rats.

Results: Forced swimming stress caused loss in body wt, reduction in sperm count, motility and SLDR in sperm analysis, reduction in serum testosterone and increase testicular MDA levels compared to control. All the changes were statistically significant. When alcohol was added along with forced swimming it caused further loss in body wt, sperm count, motility and SLDR, serum testosterone level and slightly further increase in MDA levels. These observations were also statistically significant. In case of group IV in which Vitamin E was administered long with stress with alcohol it showed a trend of reversal phenomenon of stress and alcohol induced change (Group III exhibited by gain in body wt, increase sperm count, motility and SLDR, serum testosterone and decrease in MDA level. All the results were statically significant except serum testosterone. Conclusion: Force swimming indicates that swimming is an effective model for producing stress in albino rats. The stress induced changes were further accentuated by addition of ethyl alcohol. However Vit E treatment reverses the effect of stress and alcohol.

Histological Study on Effect of Mesenchymal Stem Cell Therapy on Experimental Renal Injury Induced by Ischemia/Reperfusion in Male Albino Rat  

Science.gov (United States)

Background and Objectives Acute kidney injury (AKI) represents a major clinical problem with high mortality and limited treatment protocols. This study was planned to evaluate the therapeutic effectiveness of bone marrow - derived mesenchymal stem cells (BM-MSCs) in a rat model of ischemia/reperfusion (I/R) AKI. Methods and Results This study was carried out on thirty adult male albino rats. Animals were divided equally into three groups. Group I (control sham-operated group) (n=10), were subdivided equally into two subgroups; Ia and Ib. The experimental group (n=20) were all subjected to I/R injury by clamping both renal pedicles for 40 minutes. Half of the I/R animals did not receive MSC therapy (group II) [non-MSC treated group]. The other half of the I/R animals received single intravenous injection of PKH26 labelled BM-MSCs immediately after removal of the clamps and visual confirmation of reflow (group III) [MSC treated group]. Animals were sacrificed 24 hrs (subgroups IIa & IIIa) and 72 hrs (subgroups IIb & IIIb) after intervention. Serological measurements included serum urea and creatinine. Kidney specimens were processed for H&E, PAS and PCNA. Mean % of renal corpuscles with affected glomeruli, mean % of affected tubules, mean area % of PAS-positive reaction and mean area % of PCNA immunoreactivity were measured by histomorphometric studies and statistically compared. MSCs-treated group exhibited protection against renal injury serologically and histologically. Conclusions Results of the present study suggest a potential reno-protective capacity of MSCs which could be of considerable therapeutic promise for cell-based management of clinical AKI.

International Nuclear Information System (INIS)

An experiment on male Sprague-Dawley albino rats of 3 months old was carried out. Whole body irradiation (800, 600, 400, 200, and 0 rad) were performed after adrenalectomy, and the grade of corticosteroid in the blood plasma was then measured (Group A, B). Other groups of rats (group C, D) were injected with corticosteron and its effect on their survival was observed. The difference between its effect on the normal and that on the treated rats was not significant. It also showed that the neuro-endocrin reaction did not give beneficial effect on the irradiated rats. (author)

Effects of the leaf decoction of Momordica charantia (bitter melon) on Mitochondrial Membrane Permeability Transition Pore (MMPTP) and fertility in normal male albino rats.  

Science.gov (United States)

Momordica charantia (M. charantia), a medicinal plant of the family, Cucurbitaceae, is used in treating an array of ailments including diabetes, heamorrhoids, fevers and various cancers. Programmed cell death may be modulated by an intrinsic pathway involving the release of cytochrome C when the mitochondrial membrane permeability transition (MMPTP) pore is opened. Opening of MMPT pore was assayed using the method of Lapidus and Sokolove. The results obtained revealed that there was a dose-dependent and significant increase in the opening of the MMPT pore in rats orally administered the decoction with maximum induction (11-fold increase) at 55mg/100g body weight (bw), although the extent of opening of the pore was reduced at 65mg/100g bw (9-fold increase). An assessment of the blood parameters of animals orally exposed to the decoction showed significant decrease (p<0.05) in lymphocytes and a significant increase (p<0.05) in neutrophils at 55mg/ 100g bw. Moreover, significant increases (p<0.05) in RBC levels at 45 and 65mg/100g bw, were observed. Similarly, PCV and Heamoglobin values were also elevated at 65mg/100g bw while there was a significant reduction (p<0.05) in MCV and MCH values at 45, 55 and 65mg/100g bw. MCHC values were reduced only in animals that received 65mg/ 100g when compared to control animals. Analysis of the spermiogram of the experimental rats showed significant reductions (p<0.05) in sperm motility and sperm cell concentrations for all animals that were orally exposed to the decoction. There was a significant reduction (p<0.05) in percentage viability in animals that received 45mg/100g bw and above. Morphological abnormalities of sperm cells above the proposed percentage range (10%) were also observed in animals that received 45mg/100g bw and above. However, decoction did not show any significant effect on ALT and AST levels but there were significant increases (p<0.05) in a somewhat dose-dependent pattern in ALP and ãGT levels for all groups in comparison to the control group. These findings thus suggest dose-related negative or toxic effects of sub acute (30-day) oral administration of leaf decoction of M. charantia in albino rats and may therefore pose some danger to humans especially in regard to male fertility in individuals who rely on oral administration of the decoction in treating various ailments.

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

Directory of Open Access Journals (Sweden)

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

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

International Nuclear Information System (INIS)

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

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

Directory of Open Access Journals (Sweden)

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

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

Energy Technology Data Exchange (ETDEWEB)

The present study was designed to investigate 1,3,5-[U-{sup 14}C]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 {sup 14}C elimination, mainly as {sup 14}CO{sub 2}. During the first 12 h following the administration of 40 mg/kg of TOX the exhalation of {sup 14}CO{sub 2} was monophasic, with a half-life of 3.5 h. After the administration of 400 mg/kg, TOX was eliminated mainly as {sup 14}CO{sub 2} with the exhaled air (77%) and unchanged TOX (8%). About 3% of {sup 14}C 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 {sup 14}C bound by the erythrocytes was minute compared with the amount in blood plasma. When the higher dose of TOX was administered the efficiency of {sup 14}C 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.

Hepatotoxicity of ingested uranium in albino wistar rats  

International Nuclear Information System (INIS)

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

Directory of Open Access Journals (Sweden)

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

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

International Nuclear Information System (INIS)

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

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

International Nuclear Information System (INIS)

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

Antihyperglycemic effects of separate and composite extract of root of Musa paradisiaca and leaf of Coccinia indica in streptozotocin-induced diabetic male albino rat.  

Science.gov (United States)

We evaluated the antihyperglycaemic properties of aqueous-methanolic (40:60) extract of root of Musa paradisiaca and leaf of Coccinia indica in separate as well as in composite manner by conducting experiment on streptozotocin-induced diabetic rats. We measured food and water intake ability, the fasting blood glucose level, glucose tolerance, activities of important carbohydrate metabolic enzymes like glucose-6-phosphatase, glucose-6-phosphate dehydrogenase, hexokinase in liver along with quantification of glycogen in liver and in skeletal muscle and serum insulin level. We noted that after treatment of aqueous methanolic extract of above plant parts in separate as well as in composite manner at a concentration of 80 mg/100 g body weight/day to streptozotocin-induced diabetic rat resulted in a significant remedial effect on blood glucose level as well as carbohydrate metabolic enzymes and the quantity of liver and skeletal muscle glycogen. Serum insulin level that was diminished in streptozotocin-induced diabetic rat recovered significantly after the co-administration of extract of above plant parts. All the above parameters showed a more potent remedial effect after composite extract treatment with respect to separate treatment and none of the extract has any general metabolic toxicity induction.

Enhancement of ovulation by luteinizing hormone in cyclic albino rats.  

Science.gov (United States)

Treatment of cyclic albino rats with equine luteinizing hormone (LH) on the afternoon of proestrus significantly enhanced ovulatory capacity. The number of ova shed and the healthy corpora lutea in the ovaries were significantly increased. Ovarian proteolytic enzymes also increased significantly with LH treatment. The histologically normal graafian follicles bound to become atretic in the vehicle-treated animals were altogether absent in the LH-treated rats on the day of estrus. These results indicate that LH enhances the number of ovulations by reducing the preovulatory follicles from atresia and facilitates their rupture by increasing the amount of proteolytic enzymes in them. A single injection of porcine follicle stimulating hormone (FSH), human chorionic gonadotrophin (hCG), and pregnant mare's serum gonadotrophin (PMSG) given separately was ineffective in inducing superovulation in cyclic albino rats.

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

International Nuclear Information System (INIS)

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

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  

International Nuclear Information System (INIS)

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

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  

International Nuclear Information System (INIS)

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

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

Directory of Open Access Journals (Sweden)

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

Effect of chronic exposure to aspartame on oxidative stress in the brain of albino rats.  

Science.gov (United States)

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. PMID:22922192

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 F2? (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. Results revealed a significant decrease in the median values of the body weight and total serum antioxidants capacity (TAC in groups II and III of rats compared with the control group. A significant higher median value of TAC obtained in the groups IV and V when compared with the control group. Significant higher levels of serum and tissue Isoprostane observed in both groups II and III compared with control group. Histopathological, oxidative stress induced macroscopically degenerative with microscopical appearance of vasculitis and hemorrhage within decidua. Data of the present study demonstrated that imbalance oxidative stress status in pregnant rats occurred due to exposure to oxidant, which played an important role in the pathogenesis of abnormal pregnancy outcome. In addition antioxidants supplementation (vitamins E and C were valuable in reducing this stress.

Circadian rhythm of outside-nest activity in wild (WWCPS), albino and pigmented laboratory rats.  

Science.gov (United States)

The domestication process of the laboratory rat has been going on for several hundred generations in stable environmental conditions, which may have affected their physiological and behavioural functions, including their circadian system. Rats tested in our ethological experiments were laboratory-bred wild Norway rats (WWCPS), two strains of pigmented laboratory rats (Brown Norway and Long Evans), and two strains of albino rats (Sprague-Dawley and Wistar). Rats were placed in purpose-built enclosures and their cycle of activity (time spent actively outside the nest) has been studied for one week in standard light conditions and for the next one in round-the-clock darkness. The analysis of circadian pattern of outside-nest activity revealed differences between wild, pigmented laboratory, and albino laboratory strains. During daytime, albino rats showed lower activity than pigmented rats, greater decrease in activity when the light was turned on and greater increase in activity when the light was switched off, than pigmented rats. Moreover albino rats presented higher activity during the night than wild rats. The magnitude of the change in activity between daytime and nighttime was also more pronounced in albino rats. Additionaly, they slept outside the nest more often during the night than during the day. These results can be interpreted in accordance with the proposition that intense light is an aversive stimulus for albino rats, due to lack of pigment in their iris and choroid, which reduces their ability to adapt to light. Pigmented laboratory rats were more active during lights on, not only in comparison to the albino, but also to the wild rats. Since the difference seems to be independent of light intensity, it is likely to be a result of the domestication process. Cosinor analysis revealed a high rhythmicity of circadian cycles in all groups. PMID:23762462

Directory of Open Access Journals (Sweden)

Full Text Available Evaluation of anti-inflammatory activities along with the phytochemical screening of hot methanolic extract of A. scholaris stem bark (ASE in albino rats was undertaken. The preliminary phytochemical screening of the plant revealed the presence of tannins, alkaloids, saponins, phystosterols, phenolic compounds, glycoside and flavonoids. Oral LD50 of ASE by limit test was found to be above 2000 mg/kg. Two dose level of 200 (1/10 LD50 and 400 mg/kg (1/5 LD50 were selected for studying the anti -inflammatory activity of ASE using the carrageenan - induced acute paw oedema model in rats. The extract showed significant (p < 0.01 dose dependent reduction in rat paw oedema. The percentages of inhibition of oedema were 42.55 and 53.19 with 200 and 400 mg/kg, p.o. doses of ASE, respectively, as compared to control. The anti-inflammatory action of ASE can be attributed to its flavonoid contents, which are known to act through inhibition of prostaglandin biosynthesis.

Effect of indomethacin on colon of albino rat histopathological study  

Directory of Open Access Journals (Sweden)

Full Text Available Background and objective: Non steroidal anti-inflammatory drugs (NSAIDs are among the most widely used of all therapeutic agents. INDOMETHACIN is a nonsteroidal anti-inflammatory drug (NSAID that reduces fever, pain and inflammation. It is similar to ibuprofen (Motrin and naproxen (Naprosyn, Aleve. Indomethacin works by reducing the production of prostaglandins. Prostaglandins are chemicals that the body produces to cause fever and pain that are associated with inflammation. Indomethacin blocks the enzymes that make prostaglandins (cyclooxygenase 1 and 2 and thereby reduces the levels of prostaglandins. Methods: Adult albino rats were treated with INDOMETHACIN in a dose of 10 mg/kg/day orally. The rats were sacrificed at the end of the 1st, 2nd and 3rd week. Colon were preserved in 10%neutral formalin for 72 hours and processed for histological studies. RESULT: Microscopic examination revealed Increase in the number of columnar cells, goblet cells, and mitotic figures may be due to rapid regeneration following damage of epithelium.

Full Text Available We have studied the effect of cigarette smoke inhalation versus subcutanous nicotine injction on the liver of 40 adult male albino rats . Animals were divided into; cigarrete inhalation group and subcutaneous nicotine injection group. Inhalation group was subdivided into 5 subgroups ;three groups inhaled the smoke of two cigarettes three times a day in a closed chamber for 1,2&3 weeks respectively; a group of recovery after inhalation and a control group.The nicotine injection group was also subdivided into 5 subgroups;three groups were injected subcutaneously with 0.1ml of 1% nicotine every two days for 1,2&3 weeks respectively; a group of recovery after injection and a control group.Rats were sacrificed at the determined durations and the liver was subjected for preparation of 6 microns paraffin sections. Microscopic examination of paraffin sections stained with H&E; Masson trichrome and PASwas done and interpreted with the image analyzer. Several histological findings such as degenerative changes in hepatocytes, cellular infiltration, periportal fibrosis, and congestion of both central and portal veins have been noticed. Also, histochemical P.A.S. reaction has showed marked decrease in both groups. The mean optical density (O D of P A S in hepatocytes of cigarette group was (0.31±0.02, and that of nicotine group was (0.26±0.03, which were significantly lower than that in the control group with mean O.D. (0.54±0.5 and (0.51±0.03 respectively. In conclusion; the inhalation of nicotine in the form of cigarette smoke resulted in deteriorative changes in the liver of the male adult albino rat more than nicotine injected subcutaneously, and these changes was partialy reversed shortly after withdrawal.

ANTIFERTILITY STUDIES ON ETHANOLIC EXTRACT OF ABRUS PRECATORIUS L ON SWISS MALE ALBINO MICE  

Directory of Open Access Journals (Sweden)

Full Text Available Fertility control is an issue of global and national health concern, many study have been done for the male contraception. The use of medicinal plants in different sorts of disease including fertility problem is widespread throughout the world. Though considerable progress has been made the development of highly effective, acceptable and reversible methods of contraception among females, progress possibilities on males are still slow and limited. With recent progress towards a better understanding of male reproductive physiology there is needed to develop new contraceptive modalities for male. Abrus precatorius is one of the folk medicinal plants widely used as an antifertility agent in varius places of south Asian countries including Chittagong region of Bangladesh. The aim of the present study was to investigate the antifertility activity of abrus precarious seed extract intraperitonially administered in adult swiss male albino mice. The intraperitonial administration of 40, 80 and 80 mg/kg body weight of ethanolic seed extract of Abrus precatorius shown a highly antifertility activity which done for two months. The lower concentrations (40 mg/kg body weight of ethanolic seed extract of Abrus precatorius gave temporarily antifertility activity. But the higher dose (80 mg/kg body weight gave relatively more permanent antifertility activity on swiss albino mice compare with the control.

Modulation of morphological changes of endometrial surface epithelium by administration of composite root extract in albino rat.  

Science.gov (United States)

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

Gap junction proteins in the light-damaged albino rat  

Science.gov (United States)

Purpose Changes in connexin expression are associated with many pathological conditions seen in animal models and in humans. We hypothesized that gap junctions are important mediators in tissue dysfunction and injury processes in the retina, and therefore, we investigated the pattern of connexin protein expression in the light-damaged albino rat eye. Methods Adult Sprague-Dawley rats were exposed to intense light for 24 h. The animals were euthanized, and ocular tissue was harvested at 0 h, 6 h, 24 h, 48 h, and 7 days after light damage. The tissues were processed for immunohistochemistry and western blotting to analyze the expression of the gap junction proteins in the light-damaged condition compared to the non-light-damaged condition. Cell death was detected using the terminal deoxynucleotidyl transferase-mediated dUTP nick-end labeling (TUNEL) technique. Results Intense light exposure caused increased TUNEL labeling of photoreceptor cells. Immunocytochemistry revealed that connexin 36 (Cx36) was significantly increased in the inner plexiform layer and Cx45 was significantly decreased in the light-damaged retina. The pattern of Cx36 and Cx45 labeling returned to normal 7 days after light damage. Cx43 significantly increased in the RPE and the choroid in the light-damaged tissue, and decreased but not significantly in the retina. This elevated Cx43 expression in the choroid colocalized with markers of nitration-related oxidative stress (nitrotyrosine) and inflammation (CD45 and ionized calcium-binding adaptor molecule-1) in the choroid. Conclusions The results suggest that connexins are regulated differently in the retina than in the choroid in response to photoreceptor damage. Changes in connexins, including Cx36, Cx43, and Cx45, may contribute to the damage process. Specifically, Cx43 was associated with inflammatory damage. Therefore, connexins may be candidate targets for treatment for ameliorating disease progression.

Retinal projections to the subcortical visual system in congenic albino and pigmented rats.  

Science.gov (United States)

The primary visual pathway in albino mammals is characterized by an increased decussation of retinal ganglion cell axons at the optic chiasm and an enhanced contralateral projection to the dorsal lateral geniculate nucleus. In contrast to the primary visual pathway, little is known about the organization of retinal input to most nuclei of the subcortical visual system in albino mammals. The subcortical visual system is a large group of retinorecipient nuclei in the diencephalon and mesencephalon. These areas mediate a range of behaviors that include both circadian and acute responses to light. We used a congenic strain of albino and pigmented rats with a mutation at the c locus for albinism (Fischer 344-c/+; LaVail MM, Lawson NR (1986) Development of a congenic strain of pigmented and albino rats for light damage studies. Exp Eye Res 43:867-869) to quantitatively assess the effects of albinism on retinal projections to a number of subcortical visual nuclei including the ventral lateral hypothalamus (VLH), ventral lateral preoptic area (VLPO), olivary pretectal nucleus (OPN), posterior limitans (PLi), commissural pretectal area (CPA), intergeniculate leaflet (IGL), ventral lateral geniculate nucleus (vLGN) and superior colliculus (SC). Following eye injections of the neuroanatomical tracer cholera toxin-beta, the distribution of anterogradely transported label was measured. The retinal projection to the contralateral VLH, PLi, CPA and IGL was enhanced in albino rats. No significant differences were found between albino and pigmented rats in retinal input to the VLPO, OPN and vLGN. These findings raise the possibility that enhanced retinofugal projections to subcortical visual nuclei in albinos may underlie some light-mediated behaviors that differ between albino and pigmented mammals.

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.

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

International Nuclear Information System (INIS)

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

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.

COMBINED EFFECT OF WATER CONTAMINATION WITH COBALT AND NICKEL ON METABOLISM OF ALBINO (WISTAR RATS  

Directory of Open Access Journals (Sweden)

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

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

International Nuclear Information System (INIS)

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

Safety evaluation of Monascus purpureus red mould rice in albino rats.  

Science.gov (United States)

Monascus purpureus MTCC 410-fermented rice (red mould rice) is one of the food supplements to lower blood-lipid levels and monacolins have been proven to be the main active constituents in red mould rice (RMR). In this study, we have assessed the safety of RMR by conducting toxicological studies in albino rats. Acute and sub-chronic toxicity studies were conducted on both sexes of albino rats. Feeding acute doses of RMR at 0.5, 1.0, 2.5 and 5.0 g/kg body weight to rats did not cause any symptoms of toxicity or mortality. Similarly, dietary feeding of RMR at 2.0%, 4.0%, 8.0% and 12.0% level (w/w) for 14 weeks did not produce any significant changes in food intake or gain in body weight of the experimental rats compared to control rats. There were no significant differences in the relative weight of vital organs, hematological parameters, macroscopic and microscopic changes in vital organs and serum clinical enzyme levels between the experimental and control groups. Moreover, the rats fed with RMR showed a significant reduction in cholesterol and triglyceride levels in both serum and liver. The results showed that toxicity studies with RMR of M. purpureus did not cause any toxic effects in albino rats. PMID:19410627

RADIOPROTECTIVE EFFECT OF LYCOPENE IN GAMMA IRRADIATED ALBINO RATS  

International Nuclear Information System (INIS)

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

An experimental study of the effects of Matricaria chamomilla extract on cutaneous burn wound healing in albino rats.  

Science.gov (United States)

Previous studies conducted on the anti-inflammatory, antimicrobial and antioxidant effects of Matricaria chamomilla (chamomile) extract led us to study the effect of topical chamomile extract on burn wound healing in albino rats. Thirty male albino rats (250-300 g) were randomly divided into three groups, as control, vehicle, and treatment. Second-degree burning was induced in 20% of whole surface area of animal body by placing the back of animal into boiling water for 8s. Animals of control group received no treatment. Animals of vehicle and treatment groups were treated topically by olive oil and extract dissolved in olive oil twice a day respectively from the first day of burn induction to complete wound healing. The percentage of wound healing was calculated weekly. The results showed that there was significant difference (p < 0.05) between vehicle and treatment groups. So we concluded that the chamomile extract in the form of rubbing oil had a good potential for acceleration of burn wound healing in rats. PMID:18404562

Effect of Bone Marrow Derived Mesenchymal Stem Cells on Healing of Induced Full-Thickness Skin Wounds in Albino Rat  

Science.gov (United States)

Background and Objectives Mesenchymal stem cells have delivered new approaches to the management of wound healing in severe skin injuries. This work was planned to evaluate the effect of bone marrow-derived mesenchymal stem cells (BMSCs) on healing of induced full thickness skin wounds in albino rats using topical & systemic injections. Methods and Results Forty adult male albino rats were classified into 2 groups after induction of full thickness skin wound; untreated group and stem cell-treated group. The latter was further subdivided into topically and systemically treated ones. BMSCs were isolated & labeled by PKH26 before injection. Healing of wounds was evaluated grossly. Skin biopsies were obtained one & three weeks after wound induction. Sections were stained with Hematoxylin & Eosin, Masson's trichrome and immunohistochemichal stain for vascular endothelial growth factor (VEGF). Epidermal thicknesses and mean area percent of both collagen fibers & VEGF immunopositive cells were measured using image analyzer & results were subjected to statistical analysis. PKH26 fluorescent-labeled cells were found in the regenerated epidermis, hair follicles and dermis in BMSCs-treated groups. By the end of the third week, the wounds of BMSCs-treated groups showed full regeneration of epidermis, re-organization of collagen and decrease in VEGF immunopositive cells. Delayed wound healing was seen in 20% of systemically treated rats. Significant increase in the mean area percent of collagen fibers was detected in topically treated group. Conclusions Both methods of BMSCs injection were effective in healing of full thickness skin wound but topical method was more effective.

Alteraciones en las características morfométricas del riñón de ratas albinas machos provocadas por la ingestión crónica de etanol desde la adolescencia Alterations in the morphometric features of kidney of male albino rats provoked by chronic ingestion of ethanol from the adolescence  

Directory of Open Access Journals (Sweden)

Full Text Available En el presente trabajo se pretendió determinar las variaciones que sobre las características morfométricas del riñón provoca la ingestión crónica de etanol en ratas adolescentes, para lo cual se utilizaron 42 ratas albinas machos de 30 días de nacidas con las cuales se conformaron dos grupos de 21 animales cada uno y con tiempos de tratamiento de tres y cinco meses y con estos, dos subgrupos: experimental y control. A las ratas experimentales se les suministró etanol a dosis de 5 g/kg de peso corporal mediante cánula intraesofágica. A las controles se les administró agua en lugar de etanol, en iguales condiciones. Se emplearon cortes histológicos coloreados con técnica PAS y se estudiaron las porciones contorneadas de los túbulos proximales y distales. Se calculó el área de sección transversal tubular y se midieron los volúmenes nucleares de las células de ambos túbulos. Se comprobó que las ratas experimentales mostraron volúmenes nucleares menores que las controles. El grupo experimental mostró valores de áreas de sección transversal de los túbulos renales mayores que los controles, siendo estos valores superiores en los túbulos proximales en las ratas de cinco meses, y los distales en las ratas de tres meses. Se concluyó que en la muestra estudiada el alcoholismo crónico iniciado en la adolescencia provocó variaciones morfométricas en los túbulos proximales y distales del riñón.Present paper allowed us to determine the variations exerted by the chronic ingestion of ethanol from the adolescence on the kidney morphometric features in 42 male albino rats of 30 days born divided into two groups of 21 animal each and with the treatment times of three and five months and with these 42 animals into two subgroups: one of experimental type and other as control. The experimental rats received ethanol at 5 g/kg doses according to the body weight using an intraesophageal cannula. The control ones received water instead of ethanol in similar conditions. We used histological sections stained with PAS technique to study the outlined portions of the proximal and distal tubules. The tubular transversal section area was estimated measuring the nuclear volumes of cells in both tubules. It was demonstrated that the experimental rats showed higher values of the transversal section of renal tubules higher than the control ones, where these values were superior in proximal tubules in the five months old rats and the distal ones in the three months old. We conclude that in study sample the chronic alcoholism started during adolescence provoked morphometric variations in proximal and distal tubules of kidney.

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

Directory of Open Access Journals (Sweden)

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.

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

Directory of Open Access Journals (Sweden)

Full Text Available Aim: The aim of our present study is to assess the histophysiological changes in the ovary of immature and mature wistar strain female albino rats in response to the intraperitoneal injection of ghrelin hormone. Methods: Eighteen immature female albino rats (65 - 70 g and eighteen mature female albino rats (130 to 140 g were randomly allocated into control and treatment groups (two doses as low dose - 10µg/kg and optimum dose - 20µg/kg of body weight of ghrelin.Treatment groups were injected with ghrelin for 15 days .On 16th day the animals were sacrificed. The body weight and weight of the ovaries were measured. The ovaries were fixed in10 % buffered formalin and stained with haematoxylin and eosin. The histo-architecture of ovary was studied. Results: Administration of ghrelin indicates well defined changes like reduced number of graffian follicles, some of which show mild degenerative changes like disorganized cells. Reduction in number of corpus luteal cells, prominent Stromal tissues, congestion of blood vessels were also seen in the ovaries of animals in mature female rats of optimum dose. There was no significant change in histoarchitecture of immature ovary of treated groups. In immature and mature group there was significant increase in body weight but decreased ovarian weight in treated animals when compared with control. Conclusion: From the present study it may be concluded that ghrelin produced degenerative changes in the ovaries of mature albino rats and thus it may have a negative influence on reproductive function and affects fertility.

Full Text Available The present study aimed to clarify the effect of aqueous extracts of five plants (Nigella sativa , Aloe vera, Ferula assafoetida, Boswellia carterii Birdw and Commiphora myrrha and their mixture on liver and kidney functions and protein profiles. Eighty adult male albino rats were divided into eight groups, the first served as control group, other groups were injected with alloxan(120mg/kg b.wt. The second group served as diabetic rats, the third were treated with a mixture (0.1g/100g b.wt, the fourth was treated with Nigella sativa (0.1g/100g b.wt, the fifth was treated with Aloe vera (0.05 g/100g b.wt , the sixth was treated with Ferula assafoetida (0.1g/100g b.wt, the seventh was treated with Boswellia carterri Birdw (0.1g/100g b.wt and the eighth group was treated with Commiphora myrrha (0.05 g/100g b.wt . After thirty days of treatment half of each group was decapitated and the other one was left for 15 days without any additional treatment as recovery period to followup their hazards if present. The results revealed highly significant increase (p<0.01 in serum transaminases (aspartate ( AST and alanine (ALT, alkaline phosphates (ALP, total bilirubin, urea and creatinine and recorded highly significant decrease (p<0.01 in serum total protein , albumin and globulin concentrations in the diabetic group when compared with normal rates. Otherwise, all plants extracts treated groups showed insignificant changes in the previous parameters when compared with control one . It seams, therefore that the water extracts of these plants and their mixture have protective effect against the side effects of alloxan on liver and kidney.

CARDIOMETABOLIC PROTECTIVE EFFECTS OF SOME MEDICINAL PLANTS IN DIABETIC ALBINO RATS  

Directory of Open Access Journals (Sweden)

Full Text Available Background and aim of the study: DM represents an important independent risk factor for the development of and mortality from coronary heart disease (CHD, increasing the risk by 2 to 4 times. According to WHO data, more than 75% of patients with DM die due to vascular accidents. This study investigated the effects of some plants used in Saudi Arabia and some other Arab countries as antidiabetic agents and explores its metabolic effects. Material 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 sativa and Termis seeds. The fourth group was treated with the aqueous extract of Nigella sativa seeds (100 mg / kg of body weight, while the fifth group was treated with the aqueous extract of Foenugreek seeds (100 mg / kg of body weight. The sixth one was treated with the aqueous extract of Termis seeds (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 special stain for demonstration of the different pancreatic cells in the Islet of the Langerhans. Results: The usage of the mixture or each plant alone corrected the glucose level and insulin level. Microscopically there was definite decrease in the number and diameter of beta pancreatic cells in the diabetic group while the other pancreatic cells were not affected (alpha and delta cells. The use of medicinal plants in the different groups of this study greatly improved such cellular changes and the level of blood sugar level was corrected. Also, improve dyslipidemia present in diabetic rats. The results showed that the activity of the mixture was better when compared with Nigella, Foenugreek or Termis seeds alone. Conclusions: The water extract of the mixture is the most powerful in amelioration hyperglycemia and most of all damage effects of Alloxan on hematological parameters and lipid profile. Also, it can control most of the metabolic risk factors of CAD in diabetic rats. So it is advised to use the plant mixture as an antidiabetic agent rather than the use of each plant separately. Repeating such study with the use of variable doses may be helpful in better evaluation for the required dose.

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

International Nuclear Information System (INIS)

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

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

International Nuclear Information System (INIS)

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

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

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

Science.gov (United States)

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

Impact of sperm retrieval [corrected] on testis and epididymis: an experimental study using Wistar albino rats.  

Science.gov (United States)

The aim of this study was to analyze pathophysiological changes after testicular sperm aspiration (TESA) and microsurgical epididymal sperm aspiration (MESA) procedures. Twenty four mature male Wistar albino rats with a proven breeding history, weighing approximately 200-250 gm were used for the study. Animals were randomly divided into four groups (n = 6), i.e., control, sham-control, unilateral TESA, and MESA. Using a 22G needle, the aspiration procedures were done in testis or caudal epididymis. At the end of 60 days of survival, blood samples were collected and processed for antisperm antibody detection by enzyme-linked immunosorbent assay (ELISA). After euthanasia, testes and epididymides were collected and processed for paraffin embedding. Sections were stained with hematoxylin and eosin, and TUNEL technique. Serum antisperm antibody titer significantly increased in TESA (P < 0.001) when compared to MESA. Histomorphometric analysis indicated testicular alterations in TESA and MESA, with significant damage in TESA in both testes (P < 0.001). Following the MESA procedure, ipsilateral caudal and carpus epididymis showed significant alterations (P < 0.001) and no such alterations were seen in the ipsilateral caput and intact contralateral epididymis. TUNEL staining revealed an up-regulation of apoptosis in both contra- and ipsilateral testes of TESA. Needle prick had produced drastic and irreversible alterations in testis of TESA. Ensuing processes of immunological and inflammatory reaction had the potential to disrupt spermatogenesis and increase germ cell apoptosis. However, extrapolating conclusions from the experimental model to the clinic needs to be done cautiously. PMID:23758531

Science.gov (United States)

Imidacloprid, a neonicotinoid the newest class of major insecticide has outstanding potency and systemic action for crop protection against piercing and sucking insects pests and also highly effective for control of flea on cats and dogs. The effect of oral administration of two doses of imidacloprid 10 and 20mg/kg/day for 60 days on biochemical parameters, histopathology and protein profile of female albino rat was assessed. Average feed intake was significantly reduced (Pimidacloprid treated groups. There was significant decrease (Pimidacloprid treated groups. Microscopically, liver tissue of rats treated with higher dose of imidacloprid showed marked dilation and congestion of central vein and degeneration of hepatocytes. The exposure to imidacloprid produced histopathological changes that could be correlated with changes in the biochemical profile of female albino rats. The blood plasma proteins were examined by SDS PAGE. There was no diagnostic difference in the pattern of plasma protein profile of control and treated rats. Based on the present physiological, biochemical and histological studies it is evident that imidacloprid did not produce any significant effects at 10mg/kg/day dose but induced toxicological effects at 20mg/kg/day to female rats.

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

International Nuclear Information System (INIS)

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

Directory of Open Access Journals (Sweden)

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 sugar level was corrected. The present results showed that the activity of the mixture was the best when compared with Nigella, Foenugreek and Termis seeds. Conclusions: The water extract of the mixture is the most powerful in amelioration hyperglycemia and most of all damage effects of Alloxan on the liver and texture, hematological parameters, and lipid profile. So it is advised to use the plant mixture as an antidiabetic agent rather than the use of each plant separately. Repeating such study with the use of variable doses may be helpful in better evaluation for the required doses.

Características ultraestruturais do segmento abdominal da aorta de rato albino = Mural features of the abdominal aortic segment of albino rat  

Directory of Open Access Journals (Sweden)

Full Text Available O objetivo da presente pesquisa foi investigar as peculiaridades ultraestruturais da parede da aorta de rato. Foram utilizados sete ratos albinos, adultos jovens, dos quais foram coletados fragmentos da aorta abdominal infra-renal. Após a coleta, os segmentosvasculares foram fixados e encaminhados para a rotina de microscopia eletrônica de transmissão e varredura. As lamelas elásticas aparecem interpostas às fibras musculares lisas, sendo essa disposição principalmente notada na túnica média da parede vascular. Entre asfibras musculares lisas e as lamelas elásticas, observa-se um inter-relacionamento aparentemente estreito, feito por conexão e ancoramento entre ambos os elementos murais por meio de lamelas de colágeno. A túnica íntima da aorta abdominal do rato mostraalgumas peculiaridades ultraestruturais marcantes, tais como a interrupção, em certos locais da parede, de continuidade da lâmina elástica interna, interrupção acompanhada por poros endoteliais, de certa extensão, suprajacentes à falha na estrutura elástica intimal. Este padrão de constituição mural, com destaque aos ancoramentos elástico-musculares, via o colágeno, parece garantir propriedades fundamentais da parede vascular, concernentes à hemodinâmica, tal como o cisalhamento, normalmente notado entre os estratos superpostosda parede vascular, bem como a contratilidade e a visco-elasticidade da parede arterial.The objective of the present research was to investigate the ultrastructural peculiarities of the aortic wall of the rat. Seven young adult rats were used, from which fragments of theinfrarenal abdominal aorta were collected. After collection, the vascular segments were fixed and sent for analysis by scanning electron microscope. The elastic lamellae appear interposed with smooth muscular fibers; this pattern was verified mainly at the medial layer structure. Among the mural elements a well defined interrelationship was established through connective lamellae of the arterial wall. The collagen lamellae mainly provided anchoring among the elastic and smooth muscular constituents. The intimal layer showedspecial ultrastructural features, such as a non-continuous inner elastic lamina presented in certain sites of the vascular wall, followed by endothelial pores. This mural pattern of the abdominal aorta provided support to vascular functions such as shrinkage among the laminar composition of the arterial layers, also acting in mechanical properties of the vascular wall, such as viscoelasticity and contractility – essential actions to blood vessel hemodynamics.

Science.gov (United States)

Ingestion of aqueous 70% ethanol extract of Ballota nigra (400 mg/kg body weight for 7 days) by albino rats (n=10) was investigated to study its effects on glucose, total cholesterol, triglycerides, aspartate aminotransferase (AST), alanine aminotransferase (ALT), troponin I (TnI), serum creatine kinase (CK), total protein, total bilirubin and blood urea. Ballota nigra extract caused a significant decrease in blood glucose, total serum cholesterol and CK levels. Blood levels of TnI, AST, ALT, triglycerides, total bilirubin, total protein and blood urea were unchanged. The hypoglycemic effect of Ballota nigra extract on albino rats was further investigated by conducting a glucose tolerance test intraperitoneally (IPGTT). Healthy rats that were fasting for 18 hours followed by administration of a dose of 400 mg/kg body weight of the crude extract of Ballota nigra, orally. A significant decrease in blood glucose levels (after 15, 30, and 45 minutes) with a significant increase in serum insulin level (after 15 and 30 minute) was noted. These results suggest that, the crude extract of Ballota nigra have hypoglycemic, insulin-releasing and cholesterol lowering effects in rats. PMID:17627272

ESTROGEN INDUCED OVARIAN DAMAGE LEADING TO CARCINOGENESIS IN ALBINO RAT  

Directory of Open Access Journals (Sweden)

Full Text Available In the present study, the ovarian damage, leading to carcinogenesis after administration of estrogen was assessed. A highly potent semisynthetic 17b oestradiol estrogen, ethinyl oestradiol (EO was administered @500 ?g/kg, orally, weekly to the rats of groups 2, 3 and 4 for 12, 16 and 20 weeks, respectively. The rats of group 1 were given saline alone to serve as control. On the 13th week (Group 2, the ovarian tissues revealed severe vascular congestion and fibrosis at many places. Most of the ovarian parenchyma was replaced by fibrovascular connective tissues. On the 17th week (Group 3, more severe histopathological changes were seen. Degeneration, necrosis, fibrosis of follicular tissues, presence of homogenous mass in the lumen, infiltration of lymphocytes and thickening of blood vascular walls were quite conspicuous. On the 21st week (Group 4, these changes were much more severe and marked. Extensive fibrosis, including severe degeneration and necrosis of follicular tissues were observed. Interestingly, the papillary proliferation in surface epithelium and hyperplasia of follicular cells were observed, indicating the ovarian carcinogenesis. The extent and severity of ovarian damage were time dependent, suggesting that EO (estrogen at the dose of 500 ?g/kg, orally, weekly after prolonged period (20 weeks may cause more severe damage, leading to carcinogenesis in the rat ovary.

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

Directory of Open Access Journals (Sweden)

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

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

International Nuclear Information System (INIS)

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

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

International Nuclear Information System (INIS)

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

Antioxidative Properties of Ethyl Acetate Fraction of Globimetula braunii in Normal Albino Rats  

Directory of Open Access Journals (Sweden)

Full Text Available Globimetula braunii used in Nigerian traditional medicine for managing various diseases was investigated for its antioxidant properties in adult Swiss albino rats. The pulverized plant material was extracted in 80% methanol using Soxhlet apparatus and fractionated with hexane, chloroform, ethyl acetate, butanol and water. The crude and ethyl acetate fractions were evaluated for their effects on activities of superoxide dismutase (SOD, catalase (CAT, gluthathione peroxidase (GSH-Px, lipid peroxidation and triacylglycerol levels in rats treated orally with a daily dose of 200 mg kg-1 for 14 days. Results showed that the ethyl acetate fraction caused a significant increase (p<0.05 in the activities of superoxide dismutase, catalase, glutathione peroxidase and malonyldialdehyde (MDA levels, while the level of triacylglycerol decreased (p<0.05 compared to control. HPLC analysis showed that the crude and ethyl acetate fractions showed phenolic compounds, apigenin and naringin but only naringin was present in the ethyl acetate fraction. It is likely that endogenous Naringin may be acting in vivo both as an antioxidant and a pro-oxidant in normal albino rats.

Experimental intravenous inoculation of Klebsiella rhinoscleromatis bacilli in albino rats: a histopathological and bacteriological study.  

Science.gov (United States)

Scleroma, chronic specific granuloma of the nose and upper respiratory tract, is endemic in Egypt and many other countries. The exact pathogenesis of the disease as regards the aetiological role of Klebsiella rhinoscleromatis is contradictory. This work investigated the effect of experimental intravenous injection of K. rhinoscleromatis in albino rats to demonstrate that the micro-organism can fulfil Koch's postulates. Micro-organisms were isolated from biopsy specimens taken from nasal lesions of 10 patients in the granulomatous stage of scleroma. Specimens were subjected to bacteriological and histopathological examinations to confirm the diagnosis. A 100 microl volume of freshly prepared bacterial inoculum containing 10(8) cfu/ml was injected weekly in the tail vein of each of 30 albino rats for 5 consecutive weeks. Biopsy specimens were taken from sacrificed animals and subjected to bacteriological and histopathological examinations. Positive histopathological diagnosis of scleroma was reported in the nose of 66.7% of rats, the larynx of 46.7%, the lungs of 26.7% and liver of 20% of rats. Bacteriological techniques were successful in revealing K. rhinoscleromatis from the nose of 36.7% of rats, the larynx of 30% and the lungs of 20% of rats. Various techniques were carried out to demonstrate the micro-organisms in tissue sections. Two histochemical stains for bacteria were employed: silver and Periodic Acid Schiff (PAS) stains. Immunoperoxidase technique using Klebsiella capsular type 3 antiserum was applied. It gave positive results in 66.7% of the 6 stained liver sections in spite of negative bacteriological cultures. The histiocytic nature of the Mikulicz cells was confirmed using alpha-1 antitrypsin, an immunohistochemical marker of histiocytes, and by studying the ultrastructural features of Mikulicz cells using the transmission electron microscope.

Effect of hepatoprotective ayurvedic drugs on lipolytic activities during CCl4 induced acute hepatic injury in albino rats.  

Science.gov (United States)

Daily treatment of CCl4(3 ml/kg body wt) for 7 days induced acute hepatic necrosis in albino rats. Treatment of CCl4 caused significant alterations in the activities of acid lipase, alkaline lipase, lipoprotein lipase of liver, kidney and adipose tissue and hormone sensitive lipase of adipose tissue of albino rat. Administration of hepatoprotective ayurvedic drugs (kumari asav, kumari kalp, arogyavardhini and tamra bhasma) concomitant with CCl4 counteracted the action of CCl4 on lipolytic enzymes exhibiting hepatoprotection. The possible physiological significance of alterations in lipolytic enzymes during hepatic necrosis induced by CCl4 and hepatoprotection by the above ayurvedic drugs is discussed. PMID:8500840

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

Directory of Open Access Journals (Sweden)

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

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

Directory of Open Access Journals (Sweden)

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

HEPATOPROTECTIVE ACTIVITY OF HYDROALCOHOLIC EXTRACT OF CUSCUTA REFLEXA ROXB IN PARACETAMOL INTOXICATED ALBINO RATS  

Directory of Open Access Journals (Sweden)

Full Text Available Hepatoprotective activity of hydroalcoholic extract of Cuscuta reflexa Roxb against paracetamol induced hepatic damage in albino rats was observed. In the present study the effect of ethanolic extract of Cuscuta reflexa Roxb on blood and liver glutathione, Na+ K+- ATPase activity, serum marker enzymes, serum bilirubin, glycogen and thiobarbutiric acid reactive substances against paracetamol induced damage in rats have been studied to find out the possible mechanism of hepatoprotection. It was observed that extract of Cuscuta reflexa Roxb has reversal effects on the levels of above-mentioned parameters in paracetamol hepatotoxicity. The extract of Cuscuta reflexa Roxb functions as a hepatoprotective agent and this hepatoprotective activity of Cuscuta reflexa Roxb may be due normalization of impaired membrane function activity.

Exploring Hepatotoxicity of Benomyl: Histological and Histochemical Study on Albino Rats  

Directory of Open Access Journals (Sweden)

Full Text Available Benomyl, a fungicide of the benzimidazole group applied against a wide range of fungal diseases of crops and vegetables. The effects of benomyl on the hepatic tissue of albino rats were investigated. Treating rats with benomyl at a dose level of 1/10 LD50 three times/week for three weeks induced various histopathological changes in the liver, such as hepatic tissue impairment, cytoplasmic vacuolization of the hepatocytes, leucocytic infiltrations, congestion of blood vessels and fatty degeneration. Histochemical investigations revealed reduction in total carbohydrates, total proteins and nucleic acids (DNA, RNA in the hepatic cells. These alterations were time-dependent and were obvious in animals treated with benomyl for 3 weeks. It is speculated that one or more metabolites of benomyl may be responsible for the hepatotoxicity recorded in the present work.

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

Directory of Open Access Journals (Sweden)

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

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

Directory of Open Access Journals (Sweden)

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

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

International Nuclear Information System (INIS)

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

Protective Effect of Virgin Olive Oil (Olea europea L. Against Oxidative Damage Induced by Mercuric Chloride in Rat Albinos Wistar  

Directory of Open Access Journals (Sweden)

Full Text Available Olive oil is beneficial effects are not only related to its high content of oleic acid, but also to the antioxidant potential of its polyphenols. In this study, we assess the effects of virgin olive oil on mercuric chloride induced oxidative damage in the liver of rats. Adult male Albinos Wistar rats randomly divided into four groups, were the first was served as a control, whereas the remaining groups respectively treated with: virgin olive oil (2ml/ kg b.w; by gavage, mercuric chloride (0.5 mg/kg body weight i.p and combination of virgin olive oil and HgCl2. Change in liver enzyme activities, thiobarbituric acid reactive substances (TBARS level, antioxidants and reduced glutathione (GSH contents were determined after 2 weeks of experimental period. Exposure of rats to mercuric chloride caused a significant increase the lipid peroxidation level along with corresponding decrease in the reduced glutathione and various antioxidant enzymes in liver. And increase in serum: glucose level, APL and transaminases activities and decreased in total protein and albumin levels. Furthermore, treatment with mercuric chloride caused a marked elevation of liver weight and decreased body weight. Supplementation of virgin olive oil resulted in decreased of lipid peroxidation level and in the serum: AST, ALT and APL activities were decreased along with increase in total protein, albumin and liver GSH levels. The activities of antioxidants enzymes: glutathione peroxidase (GSH-Px and glutathione –S-transferase (GST were also concomitantly restored to near normal level by virgin olive oil supplementation to mercuric chloride intoxicated rats. Liver histological studies have confirmed the changes observed in biochemical parameters and proved the beneficial role of virgin olive oil. The results clearly demonstrate that virgin olive oil treatment augments the antioxidants defense mechanism in mercuric chloride induced toxicity and provides evidence that it may have a therapeutic role in free radical mediated diseases.

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

International Nuclear Information System (INIS)

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

International Nuclear Information System (INIS)

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

Science.gov (United States)

Hepatoprotective activity of methanolic extract of Syzygium jambos (Alston) (Linn.) leaves against Paracetamol-induced hepatic damage in Wistar albino rats was observed at two different doses, 100 and 200 mg/kg body weight. The healthy control, disease control, and standard drug Silymarin-treated groups were also maintained for the comparison. The liver marker enzymes SGOT, SGPT, ALKP, Serum Bilirubin and other metabolic parameters like total cholesterol, HDL-cholesterol were evaluated in all the experimental groups. The changes in liver function parameters were significant in comparison to disease control group and the observed efficacy was comparable to standard drug. The efficacy of the extract was found to be dose dependent. The histopathology study of liver also supports the presence of hepatoprotective activity in S. jambos by showing improved cytoarchitecture of liver cells in the treated groups. The results obtained in this study indicate necessity for further research on isolation and characterization of functional molecules from the extract. PMID:24501529

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

Effect of Calotropis procera latex on isoproterenol induced myocardial infarction in albino rats.  

Science.gov (United States)

The alcoholic extract of the latex obtained from Calotropis procera (Asclepidaceae) was evaluated for protection against isoproterenol (20 mg/100 g body wt., s.c.)-induced myocardial infarction in albino rats. The heart damage induced by isoproterenol was indicated by elevated levels of the marker enzymes such as Creatine Kinase-isoenzyme (CK-MB), Lactate dehydrogenase (LDH), Serum Glutamate Oxaloacetic Transaminase (SGOT) and Serum Glutamate Pyruvate Transaminase (SGPT) in serum with increased lipid peroxide and reduced glutathione content in heart homogenates. Microscopical examination (histopathology) was also performed on the myocardial tissue. Pretreatment with an ethanolic latex extract of Calotropis procera at a dose of 300 mg/kg body wt., administered orally thrice a day for 30 days, reduced significantly (p < 0.01) the elevated marker enzyme levels in serum and heart homogenates in isoproterenol-induced myocardial infarction. Histopathological observation revealed a marked protection by the extract in myocardial necrotic damage. PMID:15185846

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

International Nuclear Information System (INIS)

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

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

International Nuclear Information System (INIS)

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

Evaluation of antioxidant activity of leaf extract of Seabuckthorn (Hippophae rhamnoides L.) on chromium(VI) induced oxidative stress in albino rats.  

Science.gov (United States)

The present study reports the antioxidant activity of Seabuckthorn (Hippophae rhamnoides), family Elaegnaceae, on chromium induced oxidative stress in male albino rats. Oxidative stress was induced in the rats by force-feeding of potassium dichromate equivalent to a dose of 30mg/kg body weight (BW) of chromium(VI) for 30 days. Administration of chromium decreased the body weight and increased organ to body weight ratio significantly. Chromium treatment significantly decreased reduced glutathione (GSH), and increased malondialdehyde (MDA) and creatine phosphokinase (CPK) levels; further it also enhanced glutamate oxaloacetate transferase (GOT) and glutamate pyruvate transferase (GPT) levels in the serum. Different doses of the alcoholic leaf extract of Seabuckthorn were evaluated for the protection against the chromium induced oxidative stress. The results show that the leaf extract at a concentration of 100 and 250mg/kg BW protected the animals from the chromium induced oxidative injury significantly. PMID:12860317

Study on the diuretic activity of Strychnos potatorum Linn. seed extract in albino rats.  

Science.gov (United States)

Methanol extract of Strychnos potatorum Linn. seeds (SPSE) was evaluated for its diuretic activity in Wistar albino rats. The SPSE was administered at the graded doses of 200, 400, and 600 mg/kg body weight. The parameters which were taken into account during the experimental on each rat were: total urine volume (corrected for water intake during the test period), body weight before and after the experiment, and the concentration of sodium, potassium, and chloride ions in urine. The total urine volumes of the SPSE (600 mg/kg)-treated rats were evaluated nearly two and half fold then compared with the control (saline treated) group. Excretion of cations (sodium and potassium ions) and anions (chloride ions) also increased significantly with respect to the control group. The diuretic effect was comparable with that of the standard drug Furosemide. The increase of cations in the urine on treatment with Strychnospotatorum seed extract (SPSE) was dose-dependent. This effect supports the use of the Strychnos potatorum seeds as a diuretic in folk remedies. PMID:11824523

Science.gov (United States)

The present study was undertaken to elucidate the effect of Perilla frutescens fixed oil on experimental esophagitis in albino rats. A group of rats (n = 6), treated with control vehicle (0.9% NaCl in double distilled water, 3 mL/kg, i.p.) and Perilla frutescens fixed oil (100%) (1, 2, and 3 mL/kg, i.p.), or pantoprazole (30 mg/kg, i.p.), were subjected to pylorus and forestomach ligation. Animals were sacrificed after 6 h and evaluated for the gastric pH, volume of gastric juices, total acidity, esophagitis index and free acidity. Esophageal tissues were further subjected to estimations of TBARS, GSH, catalase, and SOD. Treatment with fixed oil significantly inhibited the gastric secretion, total acidity, and esophagitis index. The oil also helped to restore the altered levels of oxidative stress parameters to normal. The present study also makes evident the in vitro antihistaminic and anticholinergic activity of alpha linolenic acid (ALA) (18 : 3, n - 3) on isolated rat ileum preparation. The lipoxygenase inhibitory, histamine antagonistic, antisecretory (anticholinergic), and antioxidant activity of the oil was attributed for its efficacy in reflux esophagitis. PMID:24027769

Directory of Open Access Journals (Sweden)

Full Text Available Background: Drug-induced hepatotoxicity is a potentially serious adverse effect of antituberculosis treatment (ATT regimens containing isoniazid, rifampicin and pyrazinamide. Many in vitro and in vivo studies revealed that honey possess antioxidant property and hepotoprotective property but there is no systematic work available to test the effect of honey on antitubercular drugs induced hepatotoxicity in rats. Hence present study was carried out to explore the prophylactic and therapeutic effect of honey with its antioxidant activity against hepatotoxicity induced by antitubercular drugs (Isoniazid, Rifampicin and Pyrazinamide in albino rats. Methods: Hepatotoxicity in rats treated with antitubercular drugs (Isoniazid, Rifampicin and Pyrazinamide was studied by assessing parameters such as Serum alanine aminotransferase (ALT, Serum aspartate aminotransferase (AST, Serum total protein, Serum Malondialdehyde (MDA and Serum Superoxide dismutase activity (SOD. The effect of Honey as co-administration and administration after establishment of hepatotoxicity on above parameter was investigated. These biochemical observations were supplemented by Histopathological examination of liver. Results: Honey significantly reversed changes in serum levels of AST, ALT, MDA, SOD, total protein and also histopathological changes produced by Antitubercular drugs. It was found that honey significantly prevented as well as reversed Antitubercular drugs induced hepatotoxicity and antioxidant activity. Conclusions: The results of present study show that honey has significant prophylactic and therapeutic value against antitubercular drugs induced hepatotoxicity.

Phytochemical and acute toxicity of ethanolic extract of Enantia chlorantha (oliv) stem bark in albino rats.  

Science.gov (United States)

It is presumed that drugs sourced from herbs have lesser side effects than allopathic drugs. Enantia chlorantha is widely used in herbal medicine for the treatment of several ailments such as jaundice, malaria, fever, infective hepatitis, etc. However its toxicity profiles are not well documented. The effects of ethanolic extract of E. chlorantha stem bark on body weight changes, biochemical and haematological parameters as well as histology of vital organs (heart, kidneys and liver) were assessed. Also, the phytochemical constituent of the plant was analysed. Albino rats of both sexes were randomly divided into five groups (A-E) of five rats each and the ethanolic extract of E. chlorantha stem bark extract was administered by oral gavage in a single dose. Group A rats were administered 500 mg/kg of the extract, group B; 1000 mg/kg, group C; 2000 mg/kg, group D; 3000 mg/kg and group E rats received distilled water (10 ml/kg) and served as control. The extract caused significant (p<0.05) decreases in the levels of packed cell volume, haemoglobin concentration and red blood cell counts in a dose dependent manner. Further, significant alterations were not observed in the serum biochemical parameters analysed (AST, ALP, ALT, blood urea nitrogen, total protein, albumin, globulin and bilirubin). In addition, the extract at 1000, 2000 and 3000 mg/kg caused congestion in the heart and kidney of experimental rats. These results suggest that oral administration of E. chlorantha may produce severe toxic effects at relatively high doses, thus caution should be exercised in its use. PMID:24678252

Effect of Soybean (Glycine max L. on the Hormonal Milieu of Male Rats  

Directory of Open Access Journals (Sweden)

Full Text Available Effect of soybean (Glycine max on serum level of some sex hormones: testosterone, follicle stimulating hormone (FSH, luteinizing hormone/interstitial cell stimulating hormone (LH/ICSH, estradiol and prolactin in male rats was investigated. Twenty male albino rats of 12 weeks old with similar body weights were assigned to four groups of 5 rats each and treatment with soybean meal at 100, 200 and 300 mg kg-1 body weight, respectively daily for 8 weeks. Blood samples collected through cardiac puncture were assayed for levels of hormones. There were dose-dependent effects of the soybean meal on the serum concentration of the hormones. The treatment significantly reduced the levels of testosterone and FSH in the serum while it significantly increased the levels of estradiol, LH/ICSH and prolactin. The results show that soybean (Glycine max had strong capability to disrupt hormonal functions. Hence, its indiscriminate use could increase the risk of infertility in males.

Science.gov (United States)

Background: In congestive heart failure, nephritis, toxemia of pregnancy, premenstrual tension and hypertension associated with oedema diuretic compounds are much helpful to relieve these conditions. Aims: To study the diuretic activity of alcoholic extract of roots of Cissampelos pareira by Lipschitz method in albino rats. Methods and Material: Five groups of Albino rats were used to evaluate the diuretic activity of alcoholic extract of roots of Cissampelos pareira by using metabolic cages. The group I serves as normal control received vehicle (2% CMC in normal saline), group II with Furosemide (10 mg/Kg, p.o), Groups III, IV and V with low (100 mg/kg), medium (200 mg/kg), and high (400 mg/kg) doses of alcoholic extract of roots of Cissampelos pareira respectively. Immediately after the alcoholic extract of roots of Cissampelos pareira treatment all the rats were hydrated with saline (15 ml/kg, p.o) and 2 animals placed in each metabolic cage, kept at 21°C±0.5°C. No food and water was made available to animals for 5 hour. The total volume of urine collected with each metabolic cage was measured at the end of 5 hour. Various parameters like total urine volume and concentration of different ions i.e.; Sodium, Potassium , Chloride in the urine were measured. Results: In this model when compared to control group the alcoholic extract of roots of Cissampelos pareira treated groups at different dose levels (100,200 and 400 mg/kg) have noted with significant increase in the urine volume and also significantly enhanced the excretion of Sodium, Potassium and Chloride ions in urine. Conclusion: Results showed that single dose administration of standard Furosemide and alcoholic extract of roots of Cissampelos pareira significantly (p<0.05*, p<0.01(**), p<0.001***) increased the urine output along with an increase in elimination of Sodium, Potassium, and Chloride ions. Alcoholic extract of roots of Cissampelos pareira 400 mg/Kg produced a comparable diuretic activity with standard Furosemide. PMID:24995192

Directory of Open Access Journals (Sweden)

Full Text Available The effect of fermented melon seed oil (Citrullus lanatus (Ogiri and palm kernel oil on the plasma lipid profile of female albino rats were investigated. Rats were randomly assigned into three groups and fed diet composed with fermented melon seed oil, palm kernel oil and control diet for seven weeks. After the feeding trial, plasma total cholesterol, low density lipoprotein cholesterol were significantly higher (p<0.05 than control in palm kernel oil diet while there was no significant difference in high density lipoprotein cholesterol. In contrast, the total cholesterol and high density lipoprotein cholesterol were significantly higher (p<0.5 than control while the low density lipoprotein cholesterol was significantly lower (p<0.05 in the fermented melon seed oil diet. The Ogiri oil diet had significantly reduced LDL/HDL ratio compared with the control while the palm kernel oil diet had a higher LDL/HDL ratio. The result implies that fermented melon seed oil (Ogiri oil appears to have hypolipidemic effect while dietary intake of palm kernel oil could pose a risk for coronary artery disease on long term basis.

Full Text Available Calcium channel blockers are increasingly used for the treatment of hypertension. Hypertension is an important risk factor for liver damage and several other circulatory abnormalities. The aim of this study was to determine the effects of lacidipine in a irradiation-induced hepatocellular damage model in Deoxyc Orticosterone Acetate (DOCA-salt-induced hypertensive model in rats. In this study, animals were divided into five groups as follows: control (Group 1, hypertensive (Group 2, irradiated (Group 3, irradiated and hypertensive (Group 4 and irradiated, hypertensive and lacidipine-treated (Group 5. At the end of the experiment, the livers were removed and its homogenates were biochemically examined. Significant differences were found between values of all groups (p<0.05. Group 3 and particularly Group 4 showed significant increase in lipid peroxidation and Nitric Oxide (NO and serum tumor necrosis factor-? (TNF-? with a significant reduction in serum level of alanine amine transferase (ALT enzyme and in superoxide dismutase in red blood cells lysates. Lacidipine-treated group (5 showed a significant reduction in elevated systolic blood pressure together with a great protection of ALT and SOD enzymes from the destructive effects of irradiation and hypertension. Additionally, this CCB reduces hepatic NO and serum TNF-? levels that were increased in groups (2,3,4. The present study suggests that lacidipine has some important protective effects on liver of hypertensive irradiated albino rats.

Calcium channel blockers are increasingly used for the treatment of hypertension. Hypertension is an important risk factor for liver damage and several other circulatory abnormalities. The aim of this study was to determine the effects of lacidipine in a irradiation-induced hepatocellular damage model in Deoxyc Orticosterone Acetate (DOCA)-salt-induced hypertensive model in rats. In this study, animals were divided into five groups as follows: control (Group 1), hypertensive (Group 2), irradiated (Group 3), irradiated and hypertensive (Group 4) and irradiated, hypertensive and lacidipine-treated (Group 5). At the end of the experiment, the livers were removed and its homogenates were biochemically examined. Significant differences were found between values of all groups (p Lacidipine-treated group (5) showed a significant reduction in elevated systolic blood pressure together with a great protection of ALT and SOD enzymes from the destructive effects of irradiation and hypertension. Additionally, this CCB reduces hepatic NO and serum TNF-alpha levels that were increased in groups (2,3,4). The present study suggests that lacidipine has some important protective effects on liver of hypertensive irradiated albino rats. PMID:24511746

Number and spatial distribution of intrinsically photosensitive retinal ganglion cells in the adult albino rat.  

Science.gov (United States)

Intrinsically photosensitive retinal ganglion cells (ipRGCs) respond directly to light and are responsible of the synchronization of the circadian rhythm with the photic stimulus and for the pupillary light reflex. To quantify the total population of rat-ipRGCs and to assess their spatial distribution we have developed an automated routine and used neighbour maps. Moreover, in all analysed retinas we have studied the general population of RGCs - identified by their Brn3a expression - and the population of ipRGCs - identified by melanopsin immunodetection - thus allowing the co-analysis of their topography. Our results show that the total mean number ± standard deviation of ipRGCs in the albino rat is 2047 ± 309. Their distribution in the retina seems to be complementary to that of Brn3a(+)RGCs, being denser in the periphery, especially in the superior retina where their highest densities are found in the temporal quadrant, above the visual streak. In addition, by tracing the retinas from both superior colliculi, we have also determined that 90.62% of the ipRGC project to these central targets. PMID:23295345

Directory of Open Access Journals (Sweden)

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

Directory of Open Access Journals (Sweden)

Full Text Available Background: Curcuma longa has been shown to be a potent anti-inflammatory, antioxidant and anticarcinogenic agent. The present investigation aimed at examining the possible potential protective effect of curcuma against oxytetracyclin-induced fatty liver in an attempt to understand its mechanism of action, which may pave the way for possible therapeutic applications. Material and Methods: Albino rats were divided into two major groups, 15 rats for each. The first group was divided into three sub-groups: a control, b fatty liver group; that was injected intraperitonealy with oxytetracycline ( 120mg/kg for three consecutive days resulting in steatosis and c curcuma treated group; which was treated with curcuma ( 0.4 % of diet for 30 days after fatty liver induction . All animals were scarified after 33 days of the beginning of the experiment. The second group was divided into three subgroups: a control, b fatty liver group and c drug protection group; which received curcuma for 15 days before induction of fatty liver, then sacrificed after induction of fatty liver (3 days. Blood samples were collected for biochemical analysis. Liver specimens were obtained and fixed in 10 % formalin for histological study. Results: Fatty liver groups showed high significant increase in serum glucose, cholesterol, triglycerides, LDL cholesterol, ALT, AST, GGT, LDH, total protein, albumin, globulin, urea and creatinine while HDL cholesterol and A/G ratio were significantly decreased compared to control group. Histopathological changes were detected in liver tissue of fatty liver rats. The treatment with curcuma ameliorated the biochemical parameters and histological changes. The pre-treatment with curcuma before the induction of fatty liver also ameliorated the results but they did not turn back to the normal values. Conclusion: It is recommend to using curcuma as diet additive for fatty liver patients or those people who have hyperlipidemic family history.

Increased risk of fetal anomalies following maternally induced hypothyroidism in female albino rats  

International Nuclear Information System (INIS)

evaluate the alleged association of fetal abnormalities associated with maternal thyroid hypo function, hypothyroidism was induced in female albino rats by means of daily oral administration of carbimazole (CA) at a dose of 1 mg per rat. The female were allocated into 5 groups. Group 1. comprised female rats administered CA for 15 days prior to conception and throughout the whole gestational period unit day 20. Group 2, included pregnant rats treated with CA from the 1st to the 20 th d gestational day. Group 3, contained pregnant rats treated with CA from the 7 th to the 18 th gestational day. The animals were sacrificed at the evening of the last day assigned for the drug intake. Two groups of euthyroid pregnant rats orally received the vehicle daily from the 1st to the 20th gestational day (control 20 days) and from the 7th to 18th gestational day (control 18 days) after which they were sacrificed. Blood was then collected for quantitative hormonal evaluation and uteri were removed and dissected for embryological studies. Overall, all the CA treated groups showed reduced thyroid hormones (total T4 and T3) and elevated TSH concentration, the extent of which was amplified with prolonged drug administration. Concomitant with TSH, FSH revealed elevated values in both groups treated for longer time duration with CA (Groups 1 and 2). Accordingly, the female sex hormones showed significant fluctuations. Where estrogen levels were inversely correlated with the progesterone levels in all the CA treated groups. In the 2nd and 3rd treated groups estrogen concentrations decreased whereas progesterone levels increased. However, in the 1st experimental group treated 15 days preconception and throughout pregnancy till day 20. estrogen levels recorded an obvious rise versus an abrupt fall in the progesterone concentrations as compared to the control pregnant euthyroid hormonal values. On the other hand, embryological studies discerned, in most of the pregnant hypothyroid females, shortening and shrinkage in uteri with unequal distribution of embryos between the two horns. Moreover, a considerable number of resorption sites and dead malformed undeveloped embryos were easily recognized. The affected embryos suffered prominent bulge of eyeballs, fragile skin, Sub dermal hemorrhage, together with some deformities in the head region and the fore and hind limbs. Group 1 treated with CA for the longest experimental duration showed the highest mortality rate while Group 3 treated during the sensitive period of organogenesis (from the 7th to the 18th gestational days) revealed the highest decrement in both the length and weight measurements of the surviving embryos of the three experimental groups

Effects of crude aqueous extract of Carica papaya seeds in male albino mice.  

Science.gov (United States)

The effect of an aqueous extract of Carica papaya seeds (5 mg/kg body/day im and 20 mg/kg body wt/day oral) were investigated in male mice treated for 60 days. Reversibility studies were also carried out to elucidate if any induced effects were transient. The aqueous extract did not manifest any estrogenic effects in male mice, and LD50 studies indicated its nontoxic nature. The body weight or the weights of reproductive organs, kidney, and adrenal were not affected, indicating that the extract did not promote body weight gain through obesity or water retention. The serum SGOT, SGPT, protein, and cholesterol levels were also within the normal range in the extract-treated mice, suggesting that the extract does not influence liver function or cholesterol and protein metabolism. These data suggest that the aqueous extracts of papaya seeds is safe and could serve as an effective male contraceptive in rodents. PMID:8186628

Effect of protein deficiency on the metabolism of glycoproteins and glycosaminoglycans in albino rat skin.  

Science.gov (United States)

1. The total content of neutral sugars in skin of the weanling albino rats kept on the protein-deficient diet was increased by about 40%; this was mainly due to the increased concentration of galactose. The content of sialic acid was increased by about 20%. The collagen nitrogen was decreased significantly, with a concomitant increase of non-collagen nitrogen. At the same time, the content of sulphated glycosaminoglycans in skin was significantly decreased and that of non-sulphated glycosaminoglycans was increased. 2. Protein-deficient diet enhanced the activities of the protein-bound carbohydrate-degrading lysosomal hydrolases, viz. cathepsin D (EC 3.4.4.23), N-acetyl-beta-D-glucosaminidase (EC 3.2.1.30) and beta-D-glucuronidase (EC 3.2.1.31) both in liver and skin. The activity of liver hyaluronidase (EC 3.2.1.35) was also increased upon limitation of protein supply. 3. The changes observed in skin were accompanied by increased concentration of the protein-bound hexoses, hexosamines and sialic acids in serum, and of hexosamine and uronic acid in urine. The serum fucose remained unchanged. PMID:545953

Effect of forced swim stress on wistar albino rats in various behavioral parameters  

Directory of Open Access Journals (Sweden)

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

Observations on Chromosomal Aberrations Following the Administration of Methanol Sub-Fraction of Carica papaya Seeds for Contraception in Albino Rats and Rabbits  

Directory of Open Access Journals (Sweden)

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

Induction of functional sterility in male rats by low dose Carica papaya seed extract treatment.  

Science.gov (United States)

The result revealed that a short term administration of an aqueous extract of Carica papaya seed manifested an androgen deprived effect on the target organs and thereby caused antifertility effect in adult male albino rats. The complete loss of fertility is attributed to decline in sperm motility and alteration in their morphology as well as to reduced contractile response of the vas deferens. The androgen deprived effect of the extract led to slight alteration in the histoarchitecture and weight of the reproductive organs, mainly cauda and distal vas deferens which has been related to their greater androgen sensitivity in comparison to the other target organs and or their greatly diminished target organ response to testosterone or its metabolites. The data revealed that functional sterility could be induced in male rats by papaya extract treatment, which promises to be a potential male contraceptive. PMID:6675389

Isolating globose Basal stem cells from albino wistar rats using a highly specific monoclonal antibody.  

Science.gov (United States)

Introduction: Olfactory mucosa which is situated in the roof of the nasal cavity possesses an extremely peculiar and exceptional type of pluripotent stem cells called Globose Basal Cells (GBCs) which help in lifelong regeneration of the olfactory mucosa. Previous literature doesn't provide much knowledge on the cytological, histochemical and electrophysiological properties of these cells, as they have never been isolated in pure form. Material and Methods: Olfactory mucosa was obtained from six Albino Wistar rats by using standardized surgical and chemical separation procedures. GBCs were isolated by using different chemical, surgical and fluorescent techniques. Results: In this research work, we standardized the techniques for isolating these stem cells in pure form from rat olfactory mucosa by tagging them with GBC-III antibody and separating them from other epithelial cells by using Fluorescence Activated Cell Sorter (FACS). GBC-III antibody is a mouse monoclonal IgM antibody which recognizes a 40 kDa surface antigen, which is a laminin receptor surface protein present on the GBCs. It is a highly specific marker for GBCs, unlike the earlier antibodies used, like GBC-I, which were nonspecific markers for GBCs and showed positive reactions, even with Horizontal Basal Cells (HBCs), sustentacular cells (Sus) and duct cells. This study also standardized the techniques for surgically excising the olfactory mucosa from the nasal septum and chemically separating the olfactory epithelium from the lamina propria. Conclusion: GBCs are an important group of cells which can be exploited in future to study and treat neuro-degenerative disorders like multiple sclerosis, brain ischaemia, etc. and spinal cord trauma, as they reside in a niche similar to the microenvironment in the central nervous system and have the similar ectodermal development as the neuronal and non-neuronal cells of the CNS. Moreover, olfactory epithelium is easily accessible for autologous transplantation of GBCs for different CNS disorders. PMID:24392361

Gari Based Kwashiorkorigenic Diets Compromised Some Renal Functions in Albino Rats  

Directory of Open Access Journals (Sweden)

Full Text Available Nigeria is still considered one of the countries with the highest prevalence of protein energy malnutrition. Cassava is a staple food in many parts of Nigeria and it is processed into different forms in different parts of the country, among the commonest of which is gari, which is often consumed by many people without being supplemented explaining partly the prevalent malnutrition. In this study, we investigated the possible effects of gari-based kwashiorkorigenic diet on the renal function which is central to maintenance of homeostasis. We used 24 weanly albino rats divided into two groups. One group was fed with Low Protein Diet (LPD while the other was fed with normal Commercially Produced Diet (CPD, for 8 weeks. The results showed significant negative effects on both the growth, as shown by the body weight and the kidney size and function in the rats fed with the gari-based low protein diet. The percentage weight change (% + SD and relative kidney weight for CPD and LPD groups were +340.95+2.63 and 0.51+0.02; -2.03+0.49 and 1.03+0.07, respectively. The Blood Urea Nitrogen (BUN (mg dL-1, serum creatinine (mg dL-1 and the BUN/creatinine ratio were found to be 19.1+0.84, 0.81+ 0.11 and 24.47+1.18 in the CPD group but 93.42+6.68, 1.92+0.04 and 24.47+1.18 in the LPD group. Similarly, blood pH tended towards acidity in the test group, 6.80+0.04 compared with the control, 7.40+0.03. Therefore, we concluded that during chronic protein-energy malnutrition due to consumption of poorly supplemented gari-based diet, certain renal functions are compromised.

Histopathological effects of pesticide-cholopyrifos on kidney in albino rats  

Directory of Open Access Journals (Sweden)

Full Text Available Background: Histopathological lesions have been widely used as biomarkers for health evaluation of organism exposed to pollutants and can be used as warning symptoms for organism health. There are few reports regarding histomorphological changes in kidney following pesticide chlorpyrifos exposure which has prompted us to undertake this study. Methods: The present study was conducted on 45 inbred adult Wistar albino rats of either sex, weighing 145 ? 165 gms. These animals were randomly divided into 3 groups A, B, C. Oral Chlorpyrifos was given to the experimental groups B and C in dose of 5 mg/kg body weight and 10 mg/kg body weight respectively. Group A served as control and was left as such. 3 animals from each group were sacrificed after 1 week, 2nd week, 4th week, 6th week and 8th week of initiation of experiment to see the histological changes in the kidney architecture. Results: Group A shows no histological alterations. Group B ? No histological alterations in the kidney after 1 week. From 2 weeks-8 there was shrinkage of glomerulus at initial stages of treatment, tubular dilation, glomerular hypercellularity, hypertrophy of tubular epithelium, degeneration of renal tubules, deposition of eosin positive substance in the glomerulus and renal tubules. There were infiltration of lymphocytes in the interstitium and increased vascularity in the form of dilated vessels fibrosis and interstitial oedema. All these changes were suggestive of glomerulonephritis, acute tubular necrosis and interstitial nephritis leading to acute renal failure progressing to chronic renal failure with increasing duration. In Group C ? the Kidneys of 1 week Chlorpyrifos treated rats exhibited shrunken glomeruli and hypertrophy of renal tubular epithelium. From 2nd week- 8thweek, the changes seen were more pronounced than Group B Conclusion: The present study showed that significant histomorphological changes were caused in the kidneys of rats administered with Chlorpyrifos. These changes were markedly different from the control rats. Hence this study brought into light the renal toxicity induced by chlorpyrifos which was found to be significant at high dose level.

 The Effect of Amantadine on Clomipramine Induced Sexual Dysfunction in Male Rats  

Directory of Open Access Journals (Sweden)

Full Text Available  Objective: Several studies have reported that Clomipramine has the ability to suppress male rat sexual behavior. Literature indicatesthat the activation of brain D2 receptors causes facilitation of penile erection, and a number of reports have indicated dopamine’s involvement in sexual function. Hence this study was undertaken to investigate the effect of Amantadine, a dopamine agonists on the Clomipramine induced sexual dysfunction. Methods: The study subjects involved a total of 48 males and 48 females, 4 months old Sprague-Dawley albino rats, all housed in a group of six males and females separately in plexi glass cages in an acclimatized colony room (25±0.50C maintained on a 12/12 hr light/dark cycle. The male rats were randomly divided into four groups of 12 male rats each. Group I served as controls. Group II, III, and IV were treated with Amantadine (9 mg/kg body weight, p.o 30 min, prior to the treatment with 13.5 mg/kg, 27 mg/Kg and 54 mg/Kg bodyweight p.o of Clomipramine respectively for 60 days. The control group received vehicle 1 ml/kg p.o. The sexual behavior of the male rats was observed to determine the following parameters: mount latency, intromission latency, ejaculation latency, post ejaculatory pause, and intromission frequency. As well as the sexual behavior; serum testosterone and histopathology of the testes were also investigated in this study. Results: The results indicate that Amantadine in all aspects failed to antagonize Clomipramine induced sexual dysfunction in male rats. Even the sexual competence of male rats treated with 1/2 therapeutic dose (TD of Clomipramine failed to regain their sexual competence in the presence of Amantadine. Testicular damage and decline in testosterone levels continued in the presence of Amantadine. Conclusion: Overall, the results suggest that Amantadine could not be a safe antidote to antagonize Clomipramine induced sexual dysfunction.

Evaluation of the Influence of each of Melatonin and Chromium against Diabetes-Induced Alteration in the Testis of Albino Rats Using Light andElectron Microscopies  

Directory of Open Access Journals (Sweden)

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

Extracts of Azadirachta indica and Melia azedarach seeds inhibit folliculogenesis in albino rats  

Scientific Electronic Library Online (English)

Full Text Available SciELO Brazil | Language: English Abstract in english The seed oil of Azadirachta indica A. Juss (neem) is used in traditional medicine for its antidiabetic, spermicidal, antifertility, antibacterial, and wound healing properties. The present study was undertaken to investigate the quantitative aspects of follicular development in cyclic female albino [...] rats (135 ± 10 g; 8 groups with 6 animals in each group) after oral administration of polar (PF) and non-polar (NPF) fractions of A. indica seed extract at 3 and 6 mg kg body weight-1 day-1 and Melia azedarach Linn. (dharek) seed extract at 24 mg kg body weight-1 day-1 for 18 days. The extracts were prepared using a flash evaporator at 35°C and then dissolved in olive oil to prepare doses on a per kg body weight basis. There was a significant reduction (P = 0.05) in the number of normal single layered follicles (A. indica: 0.67 ± 0.33 and 4.67 ± 2.03 after 3 and 6 mg/kg NPF, and 3.33 ± 1.67 and 1.00 ± 1.00 after 3 and 6 mg/kg PF vs control: 72.67 ± 9.14 and M. azedarach: 0.60 ± 0.40 and 1.80 ± 1.2 after 24 mg/kg PF and NPF, respectively, vs control: 73.40 ± 7.02) and follicles in various stages (I-VII) of follicular development in all treatment groups. These extracts also significantly reduced (P = 0.05) the total number of normal follicles in the neem (14.67 ± 5.93 and 1.00 ± 1.00 after 3 and 6 mg/kg PF and 3.67 ± 0.88 and 5.33 ± 2.03 after 3 and 6 mg/kg NPF) and dharek (13.00 ± 3.58 and 14.60 ± 2.25 after 24 mg/kg NPF and PF) treatments compared to control (216.00 ± 15.72 and 222.20 ± 19.52, respectively). Currently, indiscriminate use of persistent and toxic rodenticides to control rodent populations has created serious problems such as resistance and environmental contamination. Therefore, it becomes necessary to use ecologically safe and biologically active botanical substances that are metabolized and are not passed on to the next trophic level, and that interfere with the reproductive potential particularly growth and differentiation of follicles. This may help elevate the socio-economic status of the country. Thus, the present study is an attempt to investigate the effects of A. indica and M. azedarach seed extracts on reproduction of albino rats.

Bees' Honey Protects the Liver of Male Rats against Melamine Toxicity  

Science.gov (United States)

The protective effect of natural bees' honey to the liver of male albino rats against melamine toxicity was studied. Melamine supplementation at a dose of 20000?ppm in the diet for 28 days induced adverse effects on the liver, decreased serum total protein and increased liver enzyme: alanine aminotransferase, aspartate aminotransferase, and alkaline phosphatase. Histological changes of the melamine supplemented group showed necrosis in the hepatic tissues around the central veins of the liver and precipitation of melamine crystals. Treating the male albino rats (that were presupplemented regularly with 20000?ppm melamine) with natural bees' honey at a dose of 2.5?g/kg body weight for 28 days improved both liver functions and increased serum protein. In addition, a positive impact on the shape of the cells after treatment with honey compared to the positive melamine supplemented group was observed. In conclusion, the results of this study revealed that the use of natural bees' honey has the ability to protect the liver of rats against the toxic effects of melamine.

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

International Nuclear Information System (INIS)

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

Effect Of Colchicine On The Histology Of Spleen And Testis Of Albino Rats  

Directory of Open Access Journals (Sweden)

Full Text Available The aim of this work is to study the effect of colchicine administration on the histology of spleen and testis of albino rat. Colchicine was given in a daily dose of 3mg/kg body weight for five days. Animals were sacrificed at 1, 4 and 7 days following treatment. Histopathological studies of the spleen and testis were undertaken. Histological examination of spleen showed that colchicine caused histopathological changes in spleen manifested by massive haemorrhage, highly expanded red pulps accompanied by reduced white pulps with multi small degenerated areas, disturbed architecture, degenerated areas wer occupied by the hemorrhagic areas, prominent haemosiderin deposition, increased number of megakaryocytes in red pulp and subcapsular edema. These histopathological changes depend on the duration of colchicine intake. Histological examination of the testis one, four and seven days post treatment with colchicine showed dilatation and congestion of interstitial blood vessels, moderate degeneration of spermatogoneal cells, debris of spermatozoa could be detected in the lumen of the seminiferous tubules. The testis also suffered from interstitial edema with signs of fatty degeneration and degeneration of spermatogoneal cells lining some seminferous tubules. Complete destruction with hypocellularity in the spermatogenic layers in some seminiferous tubules and others contained only the debris of germ cells and disturbed nuclei of spermatogoneal cells with appearance of giant cells with highly reduced number of Leydig cells which contained pyknotic nuclei were also noticed in some examined sections. These results indicate that colchicine is considered as a toxic drug to the spleen and testis at double therapeutic doses as indicated by the histological changes.

ROLE OF OCIMUM CANUM IN PREVENTION OF REPERFUSION-INDUCED RENAL ISCHEMIA IN WISTAR ALBINO RATS  

Directory of Open Access Journals (Sweden)

Full Text Available Acute renal failure is defined as rapid loss of renal function and has been associated with a high mortality rate. Ischemia and reperfusion (I/R injury of the kidney is the most prominent cause of intrinsic acute renal failure. Activation of reactive oxygen species is implicated in renal ischemia/reperfusion (I/R injury. This study investigated the anti-ischemic effect of hydro-alcoholic leaf extract of Ocimum canum (OC against renal I/R injury by its effect on reactive oxygen species. Wistar albino rats were administered different doses of hydro-alcoholic leaf extract of Ocimum canum (OC before renal ischemia, followed by reperfusion for 24 hours. Serum creatinine, Serum Cystatin C, serum oxaloacetate transaminase (SGOT, serum pyruvate transaminase (SGPT, blood urea nitrogen (BUN and Lactate dehydrogenase (LDH were measured for renal dysfunction. Serum and tissue Malondialdehyde (MDA, reduced glutathione (GSH levels, catalase (CAT, and superoxide dismutase (SOD levels were measured. Renal sections were analyzed for histological grading of renal injury. Hydro-alcoholic leaf extract of Ocimum canum (OC significantly reduced increased creatinine, Cystatin C, serum oxaloacetate transaminase (SGOT, serum pyruvate transaminase (SGPT, blood urea nitrogen (BUN and Lactate dehydrogenase (LDH. Ocimum canum also increased kidney superoxide dismutase activity, catalase and reduced glutathione levels and reduced the malondialdehyde levels. Hydro-alcoholic leaf extract of Ocimum canum reduced histological renal damage. These results suggest that the hydro-alcoholic leaf extract of Ocimum canum reduces renal dysfunction and injury caused by renal I/R.

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

Preliminary study on the effects of Buchholzia coriacea seed extract on male reproductive parameters in rats.  

Science.gov (United States)

The effects of methanol extract of Buchholzia coriacea seed was studied on male reproductive system of albino rats. Administration of 200mg/kg b.w.(p.o.) of the extract for 6 weeks resulted in significant reduction (P?0.05) in the weight of the epididymis and seminal vesicle, but not the testes and prostate gland. Also the weight of the visceral organs- lungs, liver, heart and kidney were unaffected. A marked decrease (Psperm motility and volume was also observed in sperm collected from the caudal epididymis of the treated animals. Sperm count and morphology were not significantly affected (Pepididymal ducts were mostly empty, though the epithelial lining appeared normal. There were fewer spermatozoa and late stage spermatids in the testes, with normal testicular epithelium. The results suggest that the extract of Buchholzia coriacea may have antifertility effects in male rats, the site of action most probably the epididymis. PMID:23652231

Effect of Zingiber officinale on fatty liver induced by oxytetracycline in albino rats  

Directory of Open Access Journals (Sweden)

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

Olanzapine-induced hepatopathy in albino rats: A newer model for screening putative hepatoprotective agents, namely silymarin  

Directory of Open Access Journals (Sweden)

Full Text Available Backgrounds: This study was conducted to establish olanzapine-induced hepatopathy in Wistar albino rats as a newer model to screen putative hepatoprotective agents namely silymarin. Materials and Methods: Albino rats were divided into three groups, namely vehicle control group (CG, olanzapine-treated group (OZ, and olanzapine plus silymarin (OZS treated groups. Both the OZ and OZS groups were treated with the same dose of intraperitoneal olanzapine for 6 weeks and group OZS additionally received oral silymarin. Baseline and terminal hepatic enzymes (SGOT, SGPT, and ALP were measured in all three groups. Results: Histopathological examination of livers of both OZ and OZS groups showed degenerative changes, whereas those of control group showed normal architecture. Liver enzyme levels showed statistically significant rise in comparison to the control group as well as the respective base line values in both the test groups, but the differences in the rise of liver enzymes between the two test groups were not statistically significant. Conclusion: Olanzapine-induced hepatopathy in rats can be used as a model for screening putative hepatoprotective agents and in our setting silymarin has failed to provide any hepatoprotection.

Studies on the hypolipidemic effects of Coconut oil when blended with Tiger nut oil and fed to albino rats  

Directory of Open Access Journals (Sweden)

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

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

Quantitative Analysis of Formation of Active Avoidance Behavior in the Hippocampus Coagulated and Intact White Albino Rats  

Directory of Open Access Journals (Sweden)

Full Text Available Unsupervised cluster analysis is proposed for analysis of active avoidance formation in three groups of albino rats: 1 intact; 2 with electrolytic lesions of neocortex over the dorsal hippocampus; and 3 with electrolytic lesions of dorsal hippocampus. The term “behavior vector” has been introduced to assess quantitatively the behavior of rats while learning. The proposed approach enables to assess active avoidance behavior in rats simultaneously by all the test parameters: 1 reaction to the light; 2 reaction to the electric irritation; and 3 inter-trial spontaneous behavior. The animals were grouped by their behavioral resemblance through the learning process. The proposed method facilitates the assessment of learning capacities in animals and paves way for getting additional information concerning correlative relationships between their learning skills and other neuroethological and neurobiological parameters.

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

International Nuclear Information System (INIS)

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

Effect of aqueous extract of Tinospora cordifolia on functions of peritoneal macrophages isolated from CCl4 intoxicated male albino mice  

Directory of Open Access Journals (Sweden)

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

Liver Regenerative Effect of Phyllanthus amarus Linn. Against Alcohol Induced Liver Cell Injury in Partially Hepatectomised Albino Rats  

Directory of Open Access Journals (Sweden)

Full Text Available The present study investigates the liver regenerative effect of Phyllathus amarus Linn against alcohol induced liver cell injury in partial hepatectomised albino rats. The oral administration of Phyllanthus amarus extracts increases the activities of thymidine kinase in regenerating rat liver at 24 h. Levels of DNA and protein analysis showed that the increase in thymidine kinase was caused by comparable increase the DNA and protein. Histopathology confirmed the mitosis counts increases to the activity of DNA. These findings suggested that Phyllanthus amarus inducing DNA synthesis by the induction of levels of synthesizing nucleic acid enzymes during liver regeneration. Phyllanthus amarus may be used, as a potential liver regenerative herb in hepatic disorders and seems to be beneficial against alcohol induced liver cell damage.

Effect of aqueous extract of Arctium lappa L. (burdock roots on the sexual behavior of male rats  

Directory of Open Access Journals (Sweden)

Full Text Available Abstract Background Arctium lappa L. root has traditionally been recommended as an aphrodisiac agent. It is used to treat impotence and sterility in China, and Native Americans included the root in herbal preparations for women in labor. However, its use has not been scientifically validated. The present study therefore investigated the effects of aqueous extract of Arctium lappa L. roots on sexual behavior in normal male rats. Methods Seventy-five albino male rats were randomly divided into five groups of 15 rats each. Rats in group 1 (control were administered 10 mL?kg body weight distilled water (vehicle, group 2 received 60 mg/kg body weight sildenafil citrate (Viagra, while those in groups 3, 4, and 5 were given 300, 600, and 1,200 mg/kg body weight, respectively, of aqueous extract of Arctium lappa L. roots in the same volume. Female albino rats were made receptive by hormonal treatment. Sexual behavior parameters in male rats were monitored on days 3, 7 and 15 by pairing with receptive females (1:3. Male serum testosterone concentrations and potency were also determined. Results Oral administration of Arctium lappa L. roots extract at 600 and 1,200 mg/kg body weight significantly increased the frequencies of mount, intromission, and ejaculation frequency (p Conclusions The results of this study demonstrate that aqueous extract of Arctium lappa L. roots enhances sexual behavior in male rats. The aphrodisiac effects of the plant extract may be related to the presence of flavonoids, saponins, lignans and alkaloids, acting via a multitude of central and peripheral mechanisms. These results thus support the traditional use of Arctium lappa L. root extract for treating impotence and sterility.

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

International Nuclear Information System (INIS)

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

Antifertility screening of plants. Part IX. Effect of five indigenous plants on early pregnancy in female albino rats.  

Science.gov (United States)

Some indigenous plants reputedly possess antifertility properties when orally administered. Various extracts of some of these plants were used in an investigation to determine antifertility activity using a method which would ultimately detect anti-zygotic, blastocystoxic, anti-implantation or early abortifacient activity in adult female albino rats of proven fertility following successful mating. The rats were laparotomized on Day 10 of pregnancy and the number recorded of implantation sites in both horns of the uterus. Results of the investigation showed that: 1) None of the extracts from stems and leaves of Argemine mexicana Linn, from the seeds of Carica papaya, and from the petroleum ether and aqueous extracts of Mentha arvenis Linn showed encouraging antifertility activity; 2) The alcoholic extracts of Mentha arvenis leaves, Sapindus trifoliatus seeds and the methanol fraction of the alcoholic extract of Sapindus trifoliatus showed 100%, 100% and 80% antifertility activity respectively; 3) the alcoholic extract of Mentha arvenis inhibited implantation in 80% of rats when administered on Days 1-3 of pregnancy suggesting that it mainly acts as an anti-zygotic agent; 4) Thhe Garica papaya seed extracts did not exhibit anti-zygotic, anti-implantation, early abortifacient or antifertility activity; 5) when the methanol fraction of Sapindus trifoliatus was administered orally in rats on pregnancy Day 4-5, it inhibited implantation on 100% of the rats suggesting that it acts mainly as a blastocystoxic agent.

The Effect of In Vivo Mobilization of Bone Marrow Stem Cells on the Pancreas of Diabetic Albino Rats (A Histological & Immunohistochemical Study)  

Science.gov (United States)

Background and Objectives The rapidly increasing number of diabetic patients across the world drew the attention to develop more effective therapeutic approaches. Recent investigations on newly differentiated insulin producing cells (IPCs) revealed that they could be derived from embryonic, adult mesenchymal and hematopoietic stem cells. This work was planned to evaluate the role of StemEnhance (Aphanizomenon flos-aquae [AFA] plant extract) in mobilizing naturally occurring bone marrow stem cells as well as in improving streptozotocin-induced diabetic rats. Methods and Results Twenty adult male albino rats were divided into four groups namely the control, the diabetic, the positive control-StemEnhance and the diabetic-StemEnhance groups. After diabetes induction by streptozotocin (STZ), rats received StemEnhance for four weeks. The mean number of blood CD34 immunopositive cells was measured by flowcytometry and random blood sugar was measured weekly. The pancreas was removed from the sacrificed rats and processed for staining with H&E and immunohistochemical staining for CD34+ve and insulin +ve cells. CD34+ve cells increased in the blood after introduction of StemEnhance. CD34+ve cells were observed in the pancreas and the insulin producing cells in the islets of Langerhans were increased from the second to the fourth week of treatment. Blood glucose level improved but it was still higher than the control level after four weeks of StemEnhance treatment. Conclusions This work points to the significant role of StemEnhance in stem cell mobilization and the improvement of diabetes mellitus.

Acceleration of vertical migration of corneal epithelial cells in albino rats during chronic immobilization stress  

Energy Technology Data Exchange (ETDEWEB)

This paper studies the effect of chronic immobilization stress on the kinetics of corneal epithelial cells from the basal layer into higher layers. Experiments were carried out on 49 male rats. The animals were given an intraperitoneal injection of tritium-thymidine and an additional application of 5 microCi of tritium-thymidine was made to its surface because the cornea has no blood supply. The animals were killed and the cornea removed for investigation. Values of the index of labeled nuclei and intensity of thymidine labeling, characterizing DNA synthesis in the corneas of the control and experimental animals showed no significant change compared with their values in a pervious series of experiments. Chronic exposure to stress increased the velocity of vertical migration of the cells from the basal layer toward the outer layers of the cornea.

The ethanolic extract of Coccinia grandis roots produced a significant (P<0.01 decrease in SGOT, SGPT, SALP, Total bilirubin and Direct bilirubin and it also produced a significant (P<0.01 increase in Total protein when compared to paracetamol treated group indicating hepatoprotective action. The ethanolic extract of Coccinia grandis root produced a significant (P<0.01 increase in SOD, CAT and GSH activity when compared to paracetamol treated group and it also produced significant (P<0.01 increase in activity of Px and GPx at 400mg/kg dose, indicating antioxidant activity. But it produced less significant in Px at 200mg/kg dose and it showed no significant activity in GPx at 200mg/kg dose. The histopathological study of liver section of rat treated with ethanolic extract of Coccinia grandis (200 and 400 mg/kg showed mild hepatocyte degeneration. It was concluded from the result that ethanolic extract of Coccinia grandis possesses hepatoprotective and antioxidant activity against paracetamol induced hepatotoxicity in wistar albino rats.

Evaluation of topical Matricaria chamomilla extract activity on linear incisional wound healing in albino rats.  

Science.gov (United States)

In this investigation, the effect of Matricaria chamomilla extract on linear incisional wound healing was studied. Thirty male Wistar rats were subjected to a linear 3 cm incision made over the skin of the back. The animals were randomly divided into three experimental groups, as control, olive oil, and treatment. Control group did not receive any drug or cold cream. Olive oil group received topical olive oil once a day from beginning of experiments to complete wound closure. Treatment group were treated topically by M. chamomilla extract dissolved in olive oil at the same time. For computing the percentage of wound healing, the area of the wound measured at the beginning of experiments and the next 2, 5, 8, 11, 14, 17, and 20 days. The percentage of wound healing was calculated by Walker formula after measurement of the wound area. Results showed that there were statistically significant differences between treatment and olive oil animals (p chamomilla administered topically has wound healing potential in linear incisional wound model in rats.

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

International Nuclear Information System (INIS)

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