    Albino mutants are useful genetic resource for studying chlorophyll biosynthesis and chloroplast development and cloning genes involved in these processes in plants.Here we report a novel rice mutant low temperature albino I (ltal) that showed albino leaves before 4-leaf stage when grown under temperature lower than 20℃,but developed normal green leaves under temperature higher than 24℃ or similar morphological phenotypes in dark as did the wild-type (WT).Our analysis showed that the contents of chlorophylls and chlorophyll precursors were remarkably decreased in the ltal mutant under low temperature compared to WT.Transmission electron microscope observation revealed that chloroplasts were defectively developed in the albino ltal leaves,which lacked of well-stacked granum and contained less stroma lamellae.These results suggested that the ltal mutation may delay the light-induced thylakoid assembly under low temperature.Genetic analysis indicated that the albino phenotype was controlled by a single recessive locus.Through map-based approach,we finally located the Ltal gene to a region of 40.3 kb on the short arm of chromosome 11.There are 8 predicted open reading frames (ORFs) in this region and two of them were deleted in ltal genome compared with the WT genome.The further characterization of the Ltal gene would provide a good approach to uncover the novel molecular mechanisms involved in chloroplast development under low temperature stress.

    In addition to hypopigmentation of the skin and red iris colouration, albino animals also display distinct physiological and behavioural alterations. However, information on the social interactions of albino animals is rare and has mostly been limited to specially bred strains of albino rodents and animals from unique environments in caves. Differentiating between the effects of albinism and domestication on behaviour in rodents can be difficult, and social behaviour in cave fish changes according to species-specific adaptations to conditions of permanent darkness. The agonistic behaviours of albino offspring of pigmented parents have yet to be described. In this study, we observed agonistic behaviour in albino and pigmented juvenile Silurus glanis catfish. We found that the total number of aggressive interactions was lower in albinos than in pigmented catfish. The distance between conspecifics was also analysed, and albinos showed a tendency towards greater separation from their same-coloured conspecifics compared with pigmented catfish. These results demonstrate that albinism can be associated with lower aggressiveness and with reduced shoaling behaviour preference, as demonstrated by a tendency towards greater separation of albinos from conspecifics.

    AIM: To use the tyrosinase minigene as a visual marker to perform microinjection training and improve the techniques related with transgene to greatly elevate the efficiency of gene transfer.METHODS: A mouse tyrosinase minigene, i.e., TyBS,in which the 2.25-kb authentic genomic 5' non-coding flanking sequence of mouse tyrosinase was fused to a mouse tyrosinase cDNA, was introduced into the fertilized eggs of outbred Kunming albino mice.RESULTS: Of the 11 animals that developed from the injected eggs, two mice (P1 and #8) exhibited pigmented hair (P1) and eyes (P1 and #8), as confirmed by PCR analysis for the tyrosinase minigene integrated into the genome. When founder P1 was bred to Kunming male mouse, six progeny out of 11 offspring inherited the transgene and the pigmented-eye phenotype.CONCLUSION: Taken together, these results suggest that this minigene encodes the active tyrosinase protein and that its 5' flanking region contains the sequences regulating the expression of mouse tyrosinase gene as expected. We have rescued the albino phenotype by introduction and expression of a functional tyrosinase minigene in the Kunming albino mouse and the transgene can be passed to subsequent generation.These findings also indicate that TyBS can be a useful visual marker gene in the co-transgenic experiments.

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

    Albino Apostichopus japonicus occur both in the wild and in captivity. The offspring of albino A. japonicus also suffer from albinism. The formation of melanin in the melanocytes is dependant on microphthalmia-associated transcription factor (MITF). To investigate the role of MITF in controlling albinism, we cloned the full-length MITF cDNA from A. japonicus and compared MITF mRNA expression in albino and normal A. japonicus. In addition, we used light and electron microscopy to compare histological samples of normal and albino A. japonicus. The body wall of albino adults was characterized by significantly lower levels of MITF expression and lower numbers of epidermal melanocytes, which also contained less melanin. In albino juvenile offspring, MITF expression levels were significantly lower 32 d after fertilization and there were fewer, and less developed, epidermal melanocytes. Thus, we conclude that albino A. japonicus have fewer melanocytes and a reduced ability to synthesize melanin, likely because of lower expression of MITF.

    In albino mammals, lack of pigment in the retinal pigment epithelium is associated with retinal defects, including poor visual acuity from a photoreceptor deficit in the central retina and poor depth perception from a decrease in ipsilaterally projecting retinal fibers. Possible contributors to these abnormalities are reported delays in neuronogenesis (Ilia and Jeffery, 1996) and retinal maturation (Webster and Rowe, 1991). To further determine possible perturbations in neuronogenesis and/or differentiation, we used cell-specific markers and refined birth dating methods to examine these events during retinal ganglion cell (RGC) genesis in albino and pigmented mice from embryonic day 11 (E11) to E18. Our data indicate that relative to pigmented mice, more ganglion cells are born in the early stages of neuronogenesis in the albino retina, although the initiation of RGC genesis in the albino is unchanged. The cellular organization of the albino retina is perturbed as early as E12. In addition, cell cycle kinetics and output along the nasotemporal axis differ in retinas of albino and pigmented mice, both absolutely, with the temporal aspect of the retina expanded in albino, and relative to the position of the optic nerve head. Finally, blocking melanin synthesis in pigmented eyecups in culture leads to an increase in RGC differentiation, consistent with a role for melanin formation in regulating RGC neuronogenesis. These results point to spatiotemporal defects in neuronal production in the albino retina, which could perturb expression of genes that specify cell fate, number, and/or projection phenotype.

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

    Albino tea has received increased attention due to its brisk flavour. To identify changes in the key chemical constituents conveying important qualities to albino tea, the metabolite profiles of four albino cultivars and one green tea cultivar were analysed. Compared to the green tea control, significantly decreased contents of chlorophyll (Chl) (ptea leaves with a few exceptions, whereas increases were noted in the Chl a/b ratio and the contents of both zeaxanthin and free amino acids, including theanine. Multivariate analysis identified catechins and carotenoids as the most important contributors to the metabolic profile variance between the albino and green tea cultivars. High levels of amino acids, along with low levels of chlorophylls, catechins and caffeine, contribute to the qualities of albino tea, which include reduced astringency and bitterness, along with a strong umami taste.

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

Macroscopicamente havia múltiplos tumores enegrecidos no músculo esquelético, pulmões, linfonodos, saco pericárdio, cápsula renal, mediastino e pleura. Microscopicamente foram observadas células epitelióides poliédricas dispostas em ninhos sólidos ou fascículos entrelaçados sustentadas por um estroma colagenoso fino e esparso. O citoplasma era eosinofílico e por vezes continham quantidades variáveis de pigmento de melanina. A taxa de mitose foi baixa. Na imuno-histoquímica houve imunomarcação positiva utilizando anticorpo anti-tirosinase, anti-Melan-A, anti-vimentina, anti-proteína S-100 e antineurofilamento. É possível que o polimorfismo relacionado com o gene da pigmentação em búfalos albinos tenha contribuído para o maior risco de desenvolvimento de melanomas, como foi sugerido em humanos.

    This article address the 'evil albino' plot device or albino bias as portrayed in films and explores how such labelling stimulates societal intolerance and discrimination against People Living With Albinism. The article reveals how media perpetuates stereotypes of albinism through their portrayal of role players and argues that the continued existence of such stereotypes is a failure to see albinism for what it is: a medical condition. The article further discusses Albinism related stigma and discrimination against the backdrop of the 'evil albino' plot device. PMID:23781766

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

    Full Text Available The present study aimed to investigate the effects of Mesobuthus tamulus gangeticus Pocock (Buthidae venom on albino mice (NIH strain. Whole venom was obtained by electrical stimulation and its toxicity was determined in albino mice by subcutaneous envenomation. The venom LD50 was 2.5 mg kg-1 of mouse body weight. Toxic effects on different biochemical and enzymatic parameters in blood serum and other tissues of albino mice were determined after experimental envenomation with sublethal doses of M. tamulus gangeticus venom. Increased levels of glucose, uric acid and cholesterol, as well as decreased serum total proteins, were observed at 2 and 4 hours after the envenomation. In the liver and muscles, glycogen content dropped after venom injection. Moreover, M. tamulus gangeticus venom elevated the enzymatic activity of acid phosphatase (ACP, lactic dehydrogenase (LDH and alanine aminotransferase (ALT in the serum of albino mice. In conclusion, M. tamulus gangeticus can be considered a lethal scorpion species.

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

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

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

Methods: The ethanolic and aqueous extract of leaves of Abutilon indicum was administered orally at the dosage levels of 200 mg/kg/day and 400 mg/kg/day body weight in mice. The assessment of immunomodulatory activity on specific and non-specific immunity were studied by heamagglutination antibody (HA titer, delayed type hypersensitivity (DTH, neutrophil adhesion test and carbon clearance test. In order to induced immunosuppresion in mice by using cyclophosphamide (100 mg/kg/day, p.o. and levamisole (50mg/kg/day, p.o. used as immunostimulating agents. Results: Oral administration of A. indicum showed a significant increase in the production of circulating antibody titre in response to sheep red blood cells (SRBCs. A significant (p<0.01 increase in both primary and secondary HA titre was observed when compared to control group, whereas in cyclophosphamide treated group A. indicum showed ignificant (p<0.01 increase in HA titre. A. indicum showed ignificantly (p<0.01 potentiated the DTH reaction by facilitating the footpad thickness response to SRBCs in sensitized mice. Also A. indicum evoked a significant (p<0.01 increase in percentage eutrophil adhesion to nylon fibers and phagocytic activity.Conclusion: The study demonstrates that A. indicum triggers both pecific and non-specific responses to a greater extent. The study comprised the acute toxicity and preliminary phytochemical screening of A. indicum. From the results obtained and phytochemical studies the immunostimulant effect of AI could be attributed to the flavonoid content.

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

    International Nuclear Information System (INIS)

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

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

    International Nuclear Information System (INIS)

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

    International Nuclear Information System (INIS)

    Full text: The radioprotective role of aqueous extract of Adhatoda vesica leaf extract against radiation induced hematological alterations in peripheral blood of Swiss albino mice was studied at various post-irradiation intervals between 6 hrs to 30 days. Oral administration of Adhatoda vesica leaf extract (800 mg / kg body weight) prior to whole-body irradiation showed a significant protection in terms of survival percentage and hematological parameters. Mice exposed to radiation (8 Gy) without Adhatoda vesica leaf extract pre-treatment exhibited signs of radiation sickness like anorexia, lethargicity, ruffled hairs and diarrhoea and such animals died within 26 days post-irradiation. The dose reduction factor (DRF=1.6) for Adhatoda vesica leaf extract was calculated from LD50/30 values. A significant decline in hematological constituents (RBCs, WBCs, Hb and Hct) was evident till day 15, at later period of observation (day 15 onwards), no animals could survive from control group whereas, in Adhatoda vesica leaf extract pre-treated irradiated group, a gradual recovery was noted in the hematological values. However, these hematological values remained significantly below the normal even till day 30. A significant decrease in GSH was recorded in control animals. Experimental animals showed a significant increase in GSH content (blood as well as liver) with respect to control, but such values remained below normal. A significant increase in TBARS level in liver and serum was evident in control animals. Although, no significant difference was noticed in such levels in normal and Adhatoda vesica leaf extract treated animals. But, a significant decrease was registered in Adhatoda vesica leaf extract pretreated irradiated animals. The results from the present study suggest that Adhatoda vesica leaf extract has radioprotective role in stimulating/protecting the hematopoietic system thereby enhancing the survival and increasing the hematological constituents in peripheral

    Full Text Available Abstract Background It is known that following chronic dosing with bupropion HCl active metabolites are present in plasma at levels that are several times higher than that of the parent drug, but the possible convulsive effects of the major metabolites are not known. Methods We investigated the convulsive liability and dose-response of the three major bupropion metabolites following intraperitoneal administration of single doses in female Swiss albino mice, namely erythrohydrobupropion HCl, threohydrobupropion HCl, and hydroxybupropion HCl. We compared these to bupropion HCl. The actual doses of the metabolites administered to mice (n = 120; 10 per dose group were equimolar equivalents of bupropion HCl 25, 50 and 75 mg/kg. Post treatment, all animals were observed continuously for 2 h during which the number, time of onset, duration and intensity of convulsions were recorded. The primary outcome variable was the percentage of mice in each group who had a convulsion at each dose. Other outcome measures were the time to onset of convulsions, mean convulsions per mouse, and the duration and intensity of convulsions. Results All metabolites were associated with a greater percentage of seizures compared to bupropion, but the percentage of convulsions differed between metabolites. Hydroxybupropion HCl treatment induced the largest percentage of convulsing mice (100% at both 50 and 75 mg/kg followed by threohydrobupropion HCl (50% and 100%, and then erythrohydrobupropion HCl (10% and 90%, compared to bupropion HCl (0% and 10%. Probit analysis also revealed the dose-response curves were significantly different (p 50 values of 35, 50, 61 and 82 mg/kg, respectively for the four different treatments. Cox proportional hazards model results showed that bupropion HCl, erythrohydrobupropion HCl, and threohydrobupropion HCl were significantly less likely to induce convulsions within the 2-h post treatment observation period compared to hydroxybupropion HCl.

    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.

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

    Full Text Available Physiological and behavioural constraints hinder albino individuals. Albino animals are rare in the wild; this trait is associated with easy detection by predators, non-native or damaged environments, and exclusively aphotic environments in total darkness. The social aspect of albinism is reported only for human beings, and the effect is distinguishable in time and space when social benefits, are used to a limited the extent. Thus far, the social consequences of albinism for animals remain unknown. We used socially established groups of the pigmented catfish, (Silurus glanis, to observe space and temporal distance detachment of albino specimens in laboratory conditions. The albino fish were separated at larger distances from the group than pigmented individuals with the same social status determined by familiarity, and this asymmetry also varied in time. Albinism-related ostracism results in a solitary existence, usually followed by enhanced predation risk. The motivation for an individual's exclusion from a group appears to be the avoidance of the predation risk that increases not only for an odd individual but also for conspecifics within a group. Our findings indicate a role for albinism in behavioural processes related to sociality in a group of conspecifics.

    Aim: To evaluate the effect of an ethanolic extract of Semecarpus anacardium fruits on spermatogenesis in albino rats. Methods: Male albino rats were fed with a 50 % ethanolic extract of Semecarpus anacardium fruit at 100 mg·kg-l·day-1, 200 mg·kg-l·day-1 and 300 mg·kg-1·day-1 for 60 days. Fertility test was performed after 60 days of treatment. Sperm motility and density were observed in the cauda epididymis. Biochemical and histological analyses of the blood and reproductive organs were done. Recovery of fertility was followed to evaluate the reversibility of drug action. Results: S. anacardium fruit extract administration resulted in spermatogenic arrest in albino rats. Thes perm motility and density was reduced significantly. The RBC and WBC counts, haemoglobin, haematocrit, blood sugar and urea were found to be within the normal range in the whole blood. The protein, cholesterol and glycogen in the testes and the fructose in the seminal vesicle were significantly decreased after the treatment. The fruit extract feeding caused marked reduction in the number of primary spermatocytes, secondary spermatocytes and spermatids.The number of mature Leydig cells was also decreased and degenerating cells increased proportionately. Conclusion:S. anacardium fruit extract causes spermatogenic arrest in albino rats. ( Asian J Androl 2003 Jun; 5: 121-124)

    Albino animals are useful for in situ hybridization experiments that demonstrate gene expression in embryos and organs, for the immunological rejection of skin grafts transplanted to host animals, and to identify tissues with regenerative ability during limbs and retina regeneration processes. Cynops pyrrhogaster has extensive regenerating capacities. To facilitate regenerative research, in the present study, we produced albino C. pyrrhogaster using genomic editing. The DNA fragment containing part of the tyrosinase gene from C. pyrrhogaster was amplified using degenerate primers corresponding to evolutionarily conserved nucleotide sequences among several species, and the nucleotide sequence was determined. We designed a transcription activator-like effector nuclease (TALEN) that targets a candidate of the C. pyrrhogaster tyrosinase gene. Fertilized eggs were injected with TALEN mRNA, and albinos of C. pyrrhogaster were obtained. The results of the present study demonstrated that TALEN can be used effectively for genomic editing in C. pyrrhogaster and that the candidates of the tyrosinase gene that were cloned by us are essential for melanin synthesis. The albino newts created in the present study can be used as versatile experimental material. PMID:27268983

    Full Text Available Abstract Background Albinism is a genetic disorder characterized by lack of skin pigmentation. It has a worldwide distribution but is commoner in areas close to the equator like Nigeria. Skin cancers are a major risk associated with albinism and are thought to be a major cause of death in African albinos. Challenges faced in the care of these patients need to be highlighted in order to develop a holistic management approach with a significant public health impact. The aim of the study was to determine the pattern of skin cancers seen in Albinos, and to highlight problems encountered in their management. Method Case records of albinos managed in Imo state University teaching Hospital from June 2007 to May 2009 were reviewed. The data obtained was analyzed using descriptive statistics. Results and discussion In the period under review, albinos accounted for 67% of patients managed for primary skin cancers. There were twenty patients with thirty eight (38 lesions. Sixty one percent of the patients were below 40 years. Average duration of symptoms at presentation was 26 months. The commonest reason for late presentation was the lack of funds. Squamous cell carcinoma was the commonest histologic variant. Most patients were unable to complete treatment due to lack of funds. Conclusion Albinism appears to be the most important risk factor in the development of skin cancers in our environment. Late presentation and poor rate of completion of treatment due to poverty are major challenges.

    The sea cucumberApostichopus japonicus is an important economic species in China. Its dorsal body wall color is commonly tawny, whereas its ventral surface is fawn. Albino sea cucumbers are rarely observed. In order to profile gene expression and screen albinism-related genes, we compared the transcriptome of albino samples with a control by 454 cDNA sequencing. We found that 6 539 identified genes on the basis of sequence similarity to known genes were expressed in the albino A. japonicus. The gene ontology analysis indicated that the transcription of genes associated with the terms of biological regulation and pigmenta-tion was non-abundant in the albino library compared to the control. Based on an analysis using the Kyoto Encyclopedia of Genes and Genomics (KEGG) database, we identified 14 important genes that were in-volved in major intercellular signaling pathways related to melanin synthesis, such as tyrosine metabolism, the mitogen-activated protein kinase (MAPK) pathway, and melanogenesis. The expressions of fibroblast growth factor receptor 4 (FGFR4), protein kinase C (PKC), protein kinase A (PKA), and Ras genes were sig-nificantly down-regulated in the albino transcriptome compared with the control, while the expressions of homogentisate 1, 2-dioxygenase gene (HGO), cAMP-responsive element binding protein (CREB), transcrip-tion factor AP-1(c-jun), and calmodulin (CaM) were significantly up-regulated (Fisher's exact test,p < 0.05). These differentially expressed genes could be candidate genes for revealing the mechanism of albinism and investigating regulation of melanin synthesis inA. japonicus.

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

  6. Analysis of the albino-locus region of the mouse. I. Orgin and viability

    International Nuclear Information System (INIS)

    Numerous specific-locus experiments designed to test the mutagenic effect of external radiation have yielded, in over 3,600,000 animals observed, altogether 119 presumed mutations involving the c locus. Of these, 55 were viable and albino (c/sup av/), 13 were viable and of various intermediate pigment types (c/sup xv/), four were subvital (c/sup as/ and c/sup xs/), seven were neonatally lethal albinos (c/sup al/), 28 prenatally lethal albinos (c/sup al/); 12 died untested. All of the prenatally lethal and at least one of the neonatally lethal c-locus mutations (c/sup al/ classes) are probably deficiencies that we have analyzed extensively in other experiments. Since absence of the locus mimics albino in phenotype, the intermediates (c/sup xv/ and c/sup xs/ groups) probably resulted from intragenic changes. The class of viable albino mutants (c/sup av/) might include, in addition to intragenic changes, some extremely small deficiencies. The effects on viability of c-locus lethals (c/sup al'/s) in heterozygous condition are not drastic enough to be perceived in stocks of mixed genetic background except in the case of the two longest known deficiencies and a few others. Analysis of the relation between radiation treatment and type of c-locus mutants obtained shows that the relative frequency of viable mutations, for each germ-cell type, is greater for low-LET than for neutron irradiation; however, the difference for any individual cell type is not significant. The majority (66.7%) of mutations derived from x- or γ-ray irradiated spermatogonia are viable, and the proportion of ''intermediates'' among these viables is similar to that among presumed spontaneous c-locus mutations

    Full Text Available Epilepsy is a neurological disorder characterized by unprovoked, recurring seizures that disrupt the nervous system and can cause mental and physical dysfunction. Based on the ethnopharmacological information of the plant, the methanol and aqueous extract of the whole plant of MELISSA OFFICINALIS was evaluated for its antiepileptic activity in Swiss Albino Mice .Antiepileptic activity was assessed by using MES and PTZ induced models (250 and 500 mg/kg. Body weight doses were used for the present study. In the MES model the methanol and aqueous extracts showed a dose dependent reduction in the duration of hind limb extensor phase. In pentylenetetrazole induced model methanol and aqueous extracts at dose level of 500mg/kg body weight showed significant reduction in the tonic convulsions induced by PTZ when compared with control group. The results suggest a possible anticonvulsant effect of the methanol and aqueous extracts of Melissa officinalis in Swiss Albino Mice.

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

    International Nuclear Information System (INIS)

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

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

    International Nuclear Information System (INIS)

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

    International Nuclear Information System (INIS)

    Skin cancer is rare among Africans and albinism is an established risk for skin cancer in this population. Ultraviolet radiation is highest at the equator and African albinos living close to the equator have the highest risk of developing skin cancers. This was a retrospective study that involved histological review of all specimens with skin cancers from African albinos submitted to The Regional Dermatology Training Center in Moshi, Tanzania from 2002 to 2011. A total of 134 biopsies from 86 patients with a male to female ratio of 1:1 were reviewed. Head and neck was the commonest (n = 75, 56.0%) site affected by skin cancers. Squamous cell carcinoma (SCC) was more common than basal cell carcinoma (BCC) with a ratio of 1.2:1. Only one Acral lentiginous melanoma was reported. Majority (55.6%) of SCC were well differentiated while nodular BCC (75%) was the most common type of BCC. Squamous cell carcinoma is more common than basal cell carcinoma in African albinos

    Wild albino and blue bilberry fruit were analyzed to compare different fruit characteristics linked to the composition of primary and secondary metabolites. Compounds were identified using HPLC-MS and standard quality parameters were determined. Albino berries were significantly smaller, accumulated less water and were characterized by 23% higher dry weight. Soluble solids content and pH value were higher in albino bilberry and their surface was lighter and characterized by a yellow hue. Both bilberry forms accumulated identical individual sugars and organic acids; however, the albino form had 33% higher content of total sugars and 9% higher content of total organic acids compared to the blue type. Fifteen anthocyanins were identified in both forms, but in albino bilberries, individual anthocyanins were only detected in traces. Blue bilberry contained 1.6-fold higher levels of flavanols, 2.1-fold higher levels of flavonols, 2.5-fold higher levels of hydroxycinnamic acid derivatives and consequently, 4.6-fold higher total phenolic content.

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

    International Nuclear Information System (INIS)

    The nature of the pathologic process in experimental adiaspiromycosis, following intraperitoneal inoculation with elements of the mycelium phase of Emmonsia crescens Emmons et Jellison (1960), depends on the reactivity of the experimental animals. Compared with a control group of animals, inoculated albino mice (with a single dose of 250 rad) contracted adiaspiromycosis more readily, there was a higher incidence of positive findings, aleirospore dissemination to distant organs outside the abdominal cavity occurred earlier, the intensity of tissue and organ insemination of the host was much higher. The results of these studies show that individuals with low resistance and increased susceptibility to infection are particularly liable to contract adiaspiromycosis. (author)

    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.)

    International Nuclear Information System (INIS)

    Adult Swiss albino mice were treated with 333 kBq/g body weight (approximately 10.22 Gy/day) intraperitoneally and sacrificed at different post-treatment intervals. It was observed that erythrocyte counts, hemoglobin and hematocrit values decreased gradually, while the depletion in leukocyte count was abrupt at early intervals after treatment. The early decline in the leukocytes followed by more gradual may be due to the direct cell killing by the isotope. The indirect effect on the hematopoietic tissues may be responsible for the continued low levels of the different blood constituents during the later intervals. (author)

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

    International Nuclear Information System (INIS)

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

    Environmental arsenic (As) is a potent human carcinogen and groundwater As contamination is a major health concern in West Bengal, India. Oxidative stress has been one of the prime factors in As-induced carcinogenicity. Generation of reactive oxygen species (ROS), beyond the body's endogenous antioxidant balance cause a severe imbalance of the cellular antioxidant defence mechanism. Tea, a popular beverage has excellent chemopreventive and antioxidant properties. In this study it was investigated whether these flavonoids could ameliorate the arsenite (As III) induced oxidative stress in Swiss albino mice. Bio-monitoring with comet assay elicited that the increase in genotoxicity caused by As III was counteracted by both black tea and green tea. Elevated levels of lipid peroxides and protein carbonyl by As III were effectively reduced with green as well as black tea. They also exhibited protective action against the As III induced depletion of antioxidants like catalase (CAT), superoxide dismutase (SOD), glutathione peroxidase (GPx), glutathione reductase (GR), glutathione-S-transferase (GST) and glutathione (GSH) in mice liver tissue. Thus the tea polyphenols by virtue of their antioxidant potential may be used as an effective agent to reduce the As III induced oxidative stress in Swiss albino mice. PMID:20096321

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

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

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

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

    Full Text Available Background: Cisplatin is one of the most effective chemotherapeutics against a wide range of cancers including head, neck, ovarian and lung cancers. But its usefulness is limited by its toxicity to normal tissues, including cells of the kidney proximal tubule. The purpose of the present study is to investigate whether the hydro-alcoholic extract of Rubia cordifolia could decrease the intensity of toxicity in Swiss albino mice. Materials and Methods: Cisplatin at a dose of 12 mg/kg body wt was administered intraperitoneally to Swiss albino mice. Another set of animals was given hydro-alcoholic extract of Rubia cordifolia at different doses along with cisplatin treatment. The antioxidant levels, serum creatinine, serum urea etc. were analyzed. Results: The extract could significantly decrease the cisplatin induced nephrotoxicity as inferred from the tissue antioxidant status in the drug administered animals. Remarkable change was observed in serum creatinine and urea levels. Lipid peroxidation in the kidney and liver tissues was also considerably reduced in Rubia cordifolia extract treated animals. Conclusion: Hydro-alcoholic extracts of Rubia cordifolia are effective in reducing the renal damage caused by the cancer chemotherapeutic drug cisplatin. Since Rubia cordifolia has been in use as an important ingredient in the traditional Ayurvedic system of medicine, it could be safe and beneficial to use this herbal extract as an adjuvant to ameliorate renal damage in patients undergoing cancer chemotherapy with cisplatin.

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

    International Nuclear Information System (INIS)

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

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

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

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

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

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

  20. Effect of imatinib on the biochemical parameters of the reproductive function in male Swiss albino mice

    A M Prasad

    2011-01-01

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

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

    International Nuclear Information System (INIS)

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

    2012-09-01

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

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

    International Nuclear Information System (INIS)

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

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

    International Nuclear Information System (INIS)

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

    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

    Full Text Available The present study was designed to demonstrate the potential effect of CGP 35348 (GABAB receptor antagonist on the learning, memory formation, and neuromuscular coordination in albino mouse. Mice were intrapertoneally injected with 1 mg CGP 35348/mL of distilled water/Kg body weight, while the control animals were injected with equal volume of saline solution. A battery of neurological tests was applied following the intrapertoneal injections. Results of rota rod indicated that CGP 35348 had no effect on neuromuscular coordination in both male (P=0.528 and female (P=0.125 albino mice. CGP 35348 treated females demonstrated poor exploratory behavior during open filed for several parameters (time mobile (P=0.04, time immobile (P=0.04, rotations (P=0.04, and anticlockwise rotations (P=0.038. The results for Morris water maze (MWM retention phase indicated that CGP 35348 treated male mice took shorter latency to reach the hidden platform (P=0.04 than control indicating improved memory. This observation was complemented by the swim strategies used by mice during training days in MWM as CGP 35348 treated males used more direct and focal approach to reach the platform as the training proceeded.

    Sea cucumber is a commercially important marine organism in China. Of the different colored varieties sold in China, albino sea cucumber has the greatest appeal among consumers. Identification of factors contributing to albinism in sea cucumber is therefore likely to provide a scientific basis for improving the cultivability of these strains. In this study, two-dimensional liquid chromatography-tandem mass spectrometry coupled with isobaric tags for relative and absolute quantification labeling was used for the first time to quantitatively define the proteome of sea cucumbers and reveal proteomic characteristics unique to albino sea cucumbers. A total of 549 proteins were identified and quantified in albino sea cucumber and the functional annotations of 485 proteins have been exhibited based on COG database. Compared with green sea cucumber, 12 proteins were identified as differentially expressed in the intestine and 16 proteins in the body wall of albino sea cucumber. Among them, 5 proteins were up-regulated in the intestine and 8 proteins were down-regulated in body wall. Gene ontology annotations of these differentially expressed proteins consisted mostly of 'biological process'. The large number of differentially expressed proteins identified here should be highly useful in further elucidating the mechanisms underlying albinism in sea cucumber. PMID:26707782

    Full Text Available To study the effect of CGP 35348 on learning and memory in albino mice following hypoxia ischemia insult, 10 days old albino mice were subjected to right common carotid artery ligation followed by 8% hypoxia for 25 minutes. Following brain damage, mice were fed on normal rodent diet till they were 13 week old. At this time point, mice were divided into two groups. Group 1 received saline and group 2 intrapertoneally CGP 35348 (1 mg/mL solvent/Kg body weight for 12 days. A battery of tests used to assess long term neurofunction (Morris water maze, Rota rod and open field along with brain infarct measurement. Overall CGP 35348 has improved the motor function in male and female albino mice but effects were more pronounced in female albino mice. In open field, CGP 35348 treated female albino mice had demonstrated poor exploratory behavior. During Morris water maze test, gender specific effects were observed as CGP 35348 had improved spatial learning and memory and swimming speed in male albino mice but had no effect in female albino mice following hypoxia ischemia encephalopathy (HIE. We concluded that GABAB receptor antagonists CGP 35348 can be used to improve gender based spatial memory.

BACKGROUND Of all the afflictions that trouble the soul, depression is the commonest characterised by a state of low mood and aversion to activity that can affect a person's thoughts, behaviour, feelings and physical well-being. Similarly, hypertension is another condition which has emerged as a major public health problem in India and many other developing countries. There is compulsion that 35% of the population has to use the antihypertensives and antidepressants simultaneously for a long period of time to maintain their health. The present work is aimed at comparing antidepressant activity of losartan with imipramine which acts by raising brain BDNF (Brain derived neurotrophic factor levels so that a single agent can be used for both the conditions avoiding multiple medications. METHOD 18 Albino mice were taken, divided into 6 mice in each group and subjected to Forced swim test. All the drugs were administered orally. Drugs were administered and time of onset of immobility is measured 60 min. after the drug administration along with total duration of immobility. Animals are exposed to pretest of 15 min., 24 hrs. prior to the 6 min. swim test. Each animal is considered immobile when it ceased to struggle and swim and remained floating in the water, only moving to keep its head above water. Control group received distilled water (10 mL/kg. Standard group received Imipramine (5 mg/kg and test group was treated with Losartan (3 mg/kg. The Forced swim test for each mouse was video captured which was later analysed to count the time of onset of immobility and total duration of immobility. RESULTS Data was analysed using Analysis of Variance (ANOVA. Losartan showed significant antidepressant activity indicated by significant delay (P<0.05 in the time of onset of immobility and significant reduction (P<0.05 in the total duration of immobility compared to

    The major objectives in radiobiology has been the development of agents that can mitigate the damage produced by ionizing radiation to normal tissues and thus reduces the side effects caused by radiation and improvement of cancer radiotherapy. The various agents have drawn attention of researchers as they provide wider acceptability and least side effects. The current study was aimed to investigate the protective effect of Aloe vera against radiation and cadmium induced changes in the liver of Swiss albino mice. For the study healthy male Swiss albino mice (6 to 8 weeks old) were selected from an inbred colony and kept in polypropylene cages. They were provided with standard mice feed and tap water ad libitum. The animals were exposed to 3.0 and 6.0 Gy of gamma radiation with or without cadmium chloride treatment. The animals of experimental groups were administered Aloe vera juice seven days prior to irradiation or cadmium chloride treatment. The animals of each group were autopsied at each post treatment interval of 1, 2, 4, 7, 14 and 28 days of treatment. The various biochemical parameters estimated were total proteins, glycogen, cholesterol, acid and alkaline phosphatase activities, DNA and RNA. After routine procedure, histopathological changes were also observed. The changes in various biochemical parameters were observed in the form of increase of decrease in values. The histopathological changes observed on day-1 after exposure to 3.0 Gy were distortion of hepatic architecture, intracellular oedema, narrower sinusoids, cytoplasmic degranulation, vacuolation and pycnotic nuclei. The changes were more marked on day-4 and continued up to day-14. But on day-28 the sign of recovery was observed. After exposure to a higher dose (6.0 Gy) similar changes were noticed but they were more pronounced and there was late manifestation of recovery. In the combined treatment of radiation and cadmium chloride synergistic effects were observed. The liver of Aloe vera treated

  19. 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 γ-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.

They showed a significant decrease in percentage of body weight change, RBCs count, Hb concentration and HCT value, while, they recorded a significant increase in WBCs, serum activity of AST and ALP, in addition to serum urea and creatinine levels in treated rats. But ALT and bilirubin showed insignificant changes throughout the experiment.

  5. Prevention of radiation-induced hepatic damage in Swiss albino mice by Aloe vera leaf extract

    International Nuclear Information System (INIS)

    The radioprotective effect of the Aloe vera leaf extract was studied in Swiss albino mice against radiation-induced changes in the liver. The mice were treated with 1000 mg/kg of body weight orally, once a day for 15 consecutive days, before exposure to a single dose of gamma radiation (6 Gy), half an hour after the last administration. The irradiation of mice caused a significant elevation in lipid peroxidation followed by a decrease in glutathione, acid phosphatase and alkaline phosphatase. The treatment of mice before irradiation elevated the glutathione, acid phosphatase and alkaline phosphatase, and was accompanied by a decline in lipid peroxidation. Recovery and regeneration from radiation damage were faster in pretreated animals than the animals in the irradiation-only group. The data clearly indicate that the Aloe vera leaf extract significantly reduced the deleterious effects of radiation on the liver and it could be a useful agent in reducing the side effects of therapeutic radiation.

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

    International Nuclear Information System (INIS)

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

This mutation appeared in a flock of completely black chickens of a private breeder. There are no information on the origin, breed, or specific line of the birds. Pigment inhibition is apparently complete in the feathers and eyes. Bird sight is very impaired, but no histological examination was carried out. Ratios obtained in F2 and backcrossed birds indicate that a single autosomal recessive gene is responsible for the condition. The data suggest that the absence of melanin in the eyes, skin, and feathers (symbol cc is a mutation of the pigmented C wild gene.

    Full Text Available The aim of the present work is evaluate to Anxiolytic profile of Hypericum hookerianum in stress induced Swiss albino mice. The study was carried out using Swiss albino mice (25- 30 g. The Anxiolytic effect of aerial parts of ethanolic extract of Hypericum hookerianum was evaluated by using behavioral analysis like Elevated plus maze (EPM test, Open Field Test (OFT, Hole Board Test (HBT, Light dark exploration Test (LDE in restraint stress induced animals. Behavioral test parameters for anxiety were assessed followed by biochemical parameters (lipid per oxidation, super oxide dismutase, catalase, glutathione per oxidase, reduced glutathione, etc. and Diazepam 1 mg/kg served as a standard Anxiolytic drug, administered intraperitonealy. The results were shown that, ethanolic extract of H.hookerianum (Hh 100mg/kg and Hh 200 mg/kg, p.o. significantly increased the percentage of time spent and number of entries in open arm in EPM. In LDE, the extract produced significant increase in time spent, number of crossing and decrease in the duration of immobility in light box. In OFT, the extract showed significant increase in number of rearings, assisted rearings and number of square crossed, all of which are demonstrations of exploratory behavior. Biochemical analyses revealed an increase in lipid per oxidation, depletion of super oxide dismutase, reduced glutathione, catalase activity and glutathione per oxidase in stress induced animals as compared to unstressed animal. Six days treatment of Hh (100 mg/kg, 200 mg/kg comparable with Diazepam, significantly attenuated restraint stress-induced behavioral and oxidative damage. The results of the present study suggest that an ethanolic extract of H.hookerianum may possess Anxiolytic activity in stressed animals and provide a scientific evidence for its traditional claim.

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

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

  1. Using the Tg(nrd:egfp/albino zebrafish line to characterize in vivo expression of neurod.

    Full Text Available In this study, we used a newly-created transgenic zebrafish, Tg(nrd:egfp/albino, to further characterize the expression of neurod in the developing and adult retina and to determine neurod expression during adult photoreceptor regeneration. We also provide observations regarding the expression of neurod in a variety of other tissues. In this line, EGFP is found in cells of the developing and adult retina, pineal gland, cerebellum, olfactory bulbs, midbrain, hindbrain, neural tube, lateral line, inner ear, pancreas, gut, and fin. Using immunohistochemistry and in situ hybridization, we compare the expression of the nrd:egfp transgene to that of endogenous neurod and to known retinal cell types. Consistent with previous data based on in situ hybridizations, we show that during retinal development, the nrd:egfp transgene is not expressed in proliferating retinal neuroepithelium, and is expressed in a subset of retinal neurons. In contrast to previous studies, nrd:egfp is gradually re-expressed in all rod photoreceptors. During photoreceptor regeneration in adult zebrafish, in situ hybridization reveals that neurod is not expressed in Müller glial-derived neuronal progenitors, but is expressed in photoreceptor progenitors as they migrate to the outer nuclear layer and differentiate into new rod photoreceptors. During photoreceptor regeneration, expression of the nrd:egfp matches that of neurod. We conclude that Tg(nrd:egfp/albino is a good representation of endogenous neurod expression, is a useful tool to visualize neurod expression in a variety of tissues and will aid investigating the fundamental processes that govern photoreceptor regeneration in adults.

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

    International Nuclear Information System (INIS)

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

  9. Prevention of radiation and cadmium induced haematological alternations in the Swiss albino mice by Aloe Vera

    International Nuclear Information System (INIS)

    The development of effective radio protectors and radio recovery drugs is of great importance in view of their potential application during both planned (i.e., radiotherapy) and unplanned radiation exposure (i.e., in the nuclear industry and natural background radiation). The combined effect of radiation and cadmium further increases the causation of damages to organs and tissues. Aloe vera has enjoyed a reputation as a healer for millennia, based primarily on anecdotal evidence. For the last 40 years concerted efforts by the scientific research community has brought Aloe vera out of the realm of folk medicine, providing it solid medical and scientific foundation. Haematopoietic organs are among the most radiosensitive cells in the living organisms. Therefore, present study was carried out to study the modulatory influence of Aloe vera against radiation and cadmium induced hematological changes in the Swiss albino mice. For the study, six to eight weeks old male Swiss albino mice were procured and kept in polypropylene cages.The animals were exposed 3.5 Gy and 7.0 Gy of gamma radiation with or without cadmium chloride treatment. The Aloe vera was administered seven days prior to irradiation or cadmium chloride treatment. Five animals from each group were autopsied by cervical dislocation at each post treatment interval of 1, 2, 4, 7, 14 and 28 days. Blood was collected in heparinized tubes to estimate various haematological parameters viz. RBC, WBC, PCV, Haemoglobin and MCV. Radiation exposure resulted in a significant decline in RBC, WBC, PCV, Haemoglobin and MCV up to day-14 in peripheral blood, thereafter it increased up to day-28 without reaching to normal. After combined treatment of radiation and cadmium chloride the more severe changes were noticed showing synergistic or additive effect. An early and fast recovery was seen in Aloe vera pretreatment groups. Thus, it may be concluded from above observation that Aloe vera has the potential of combating the

    Full Text Available BACKGROUND: Fluoride is present in environment in various forms and ingested by man from solid foods, drinks, drinking water and inhaled from the air. Out of these, fluoride is present in large quantities in dissolved state in many sources of drinking water producing toxicity in man. Fluoride, being excreted mainly through the kidneys, seems to damage it causing renal dysfunction. Kidneys are among the most sensitive body organs in their histopathological and functional responses to excessive amounts of fluoride. Trace elements are essential and beneficial to human being in minute concentrations. However, intake in large quantities produces adverse and toxic effects on our body. OBJECTIVE: The present study was designed to investigate the toxic effects (evaluated as histopathological changes of sodium fluoride on the kidney in albino rabbit. MATERIALS AND METHODS: Total 40 albino rabbits were used for this study, among them 8 rabbits were taken in the control group (Group A and16 rabbits each were taken in both group B and group C who were administered low and high dose of fluoride respectively. After 2 weeks interval, up to 16 weeks the histology of the kidney of each group of the rabbit was studied for histological analysis. RESULT: Histological changes in the kidneys of both Group B and Group C rabbits, following continuous daily exposure to sodium fluoride solutions in two different doses (0.5% solution for Group B and 3% solution for Group C for different durations of time were studied in detail and compared with those of the controls (Group A. CONCLUSION: It is concluded that Sodium Fluoride solution in high doses for prolonged period has a definite adverse effect on the renal parenchyma.

    Full Text Available A few individuals of albino Horay-bellied Squirrels along with normal gray individuals of Callosciurus pygerythrus have been observed in Sibsagar district of Assam, India. One albino female was studied in captivity. This paper presents our observations on the breeding behaviour and the parental care exhibited by the albino squirrel in captivity. The squirrel bred twice in captivity with a normal male of the same species. In both the periods, a single male baby with normal coat colour developed. Oral dose of vitamin E has been found helpful in the breeding of the studied squirrel species. The mother squirrel exhibited parental care by carrying her baby using her mouth, to a safer place during danger. However, the observed phenomenon is unlike that of the cat species. Some of the habitat ecology and feeding habits of the albino squirrels have also been studied, both in natural and in captive conditions.

  16. Variations in the villus cell population of intestine in the irradiated Swiss albino mouse with and without herbal treatment

    International Nuclear Information System (INIS)

    Generally, the effects of radiations are hazardous, even in moderate doses. The damage caused by radiation is influenced by the relative radiosensitivity of the tissue. Damage to gastrointestinal tract leads to death of the animals 10 to 15 days after radiation exposure to the lethal dose. When Swiss albino mice were irradiated with 6 and 8 Gy of gamma radiation, it caused cytological, pathological and biochemical changes in the gastrointestinal tract. There was a significant decrease in the total cell population (TCP), whereas pyknotic nuclei (PN) and necrotic cells (NC) showed significant increase after irradiation. Pretreatment with Centella asiatica (CA) resulted in a significantly lesser decrease in TCP, whereas, PN and NC showed significant decrease from respective irradiated controls at each autopsy day. It was observed that CA pretreatment provides protection against radiation induced damage in the intestinal mucosa of Swiss albino mice. (author)

    Full Text Available The experiment was carried out to determine if partial replacement of maize with cassava root meal (CRM in diets for albino rats will have an effect on performance, organ characteristics and blood parameters. Twenty five Sprague Dawley albino rats (F344 strain, initial body weight (216 ± 8g were randomly assigned to five treatments (T1 to T5 in a completely randomized (CRD arrangement. T1 was the control and contained zero CRM. T2 and T3 contained 30% CRM, while T4 and T5 contained 45% CRM. These levels of inclusion represented 50 and 75% replacement of corn in the diets respectively. T2 and T4 had 0.15% methionine (Met while T3 and T5 had 0.3% Met. The rats were each fed a single diet for 28d. Average daily feed intake (ADFI of rats on T1 was lower (P 0.05 in average daily gain (ADG and feed conversion efficiency (FCE. Similarly there were no differences (P>0.05 in carcass, viscera and other internal organ weights. Results of this trial indicate that albino rats can tolerate diets with added CRM (45% of the diet with no adverse effects on growth and internal organ characteristics. Future work will need to look at the possibility of using CRM at similar or higher levels in diets for growing pigs.

    The distribution and ultrastructure of pigment cells in skins of normal and albino adult turbots were examined with transmission electron microscopy (TEM). Three types of pigment cells of melanophore, iridophore and xanthophore have been recognized in adult turbot skins. The skin color depends mainly on the amount and distribution of melanophore and iridophore, as xanthophore is quite rare. No pigment cells can be found in the epidermis of the skins. In the pigmented ocular skin of the turbot, melanophore and iridophore are usually co-localized in the dermis. This is quite different from the distribution in larvae skin. In albino and white blind skins of adult turbots, however, only iridophore monolayer still exists, while the melanophore monolayer disappears. This cytological evidence explains why the albino adult turbot, unlike its larvae, could never resume its body color no matter what environmental and nutritional conditions were provided. Endocytosis is quite active in the cellular membrane of the iridophore. This might be related to the formation of reflective platelet and stability of the iridophore.

    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.

    Full Text Available Abstract Background It has long been known that cerebrospinal fluid (CSF, its composition and flow, play an important part in normal brain development, and ependymal cell ciliary beating as a possible driver of CSF flow has previously been studied in mammalian fetuses in vitro. Lower vertebrate animals are potential models for analysis of CSF flow during development because they are oviparous. Albino Xenopus laevis larvae are nearly transparent and have a straight, translucent brain that facilitates the observation of fluid flow within the ventricles. The aim of these experiments was to study CSF flow and circulation in vivo in the developing brain of living embryos, larvae and tadpoles of Xenopus laevis using a microinjection technique. Methods The development of Xenopus larval brain ventricles and the patterns of CSF flow were visualised after injection of quantum dot nanocrystals and polystyrene beads (3.1 or 5.8 μm in diameter into the fourth cerebral ventricle at embryonic/larval stages 30-53. Results The fluorescent nanocrystals showed the normal development of the cerebral ventricles from embryonic/larval stages 38 to 53. The polystyrene beads injected into stage 47-49 larvae revealed three CSF flow patterns, left-handed, right-handed and non-biased, in movement of the beads into the third ventricle from the cerebral aqueduct (aqueduct of Sylvius. In the lateral ventricles, anterior to the third ventricle, CSF flow moved anteriorly along the outer wall of the ventricle to the inner wall and then posteriorly, creating a semicircle. In the cerebral aqueduct, connecting the third and fourth cerebral ventricles, CSF flow moved rostrally in the dorsal region and caudally in the ventral region. Also in the fourth ventricle, clear dorso-ventral differences in fluid flow pattern were observed. Conclusions This is the first visualisation of the orchestrated CSF flow pattern in developing vertebrates using a live animal imaging approach. CSF flow

    The dorsal and ventral vertebral muscles of the back and the tail of the albino Norway rat are described and discussed. These muscles were analyzed because they are undoubtably used during the sexual posturing, lordosis, of the female rat, as well as participating in a variety of other behaviors. The muscles are described by region (thoracic-lumbar or sacrocaudal), and the classifications of Vallois are followed where possible. Of the epaxial (dorsal) muscles, the three longitudinal systems of muscles, the transversospinalis, the longissimus, and the iliocostalis systems, can be identified in the albino rat. Muscles of the transversospinalis system are fused in the lumbar region, distinct and specialized in the thoracic region, and form the tail muscle extensor caudae medialis caudally. The iliocostalis system of the lumbar region is fused with one component of the lumbar longissimus system to form lateral longissimus. Anteriorly, iliocostalis thoracis and cervicis represent the iliocostalis system. The lumbar longissimus system is represented by the longissimus component of lateral longissimus, medial longissimus, and a short-fiber component. Longissimus dorsi is the anterior continuation of the longissimus portion of the lateral longissimus. The short-fiber component also continues into the thoracic region, where it becomes difficult to separate out from longissimus dorsi. Medial longissimus represents the excursion into the lumbar region of the long, tendinous, tailbase-tail muscle, longissimus caudae; the caudal portion of this muscle is extensor caudae lateralis. The remaining dorsal muscle described is the tail muscle, abductor caudae dorsalis. The hyposomal (ventral) muscles described are quadratus lumborum and the intertransversarii, present in the lumbar region; the muslces iliococcygeus, pubococcygeus and coccygeus which arise from the medial face of the pelvis and insert onto the proximal tail; the long, tendinous, tail muscles, flexor caudae brevis and

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

    International Nuclear Information System (INIS)

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

    Full Text Available The choice of safe and effective method for fertility control still under continuous search. So, discovery of structures having long duration of action which made administration by injection was an attractive alternative to oral contraceptives. Medroxyprogesterone acetate emerged from this early work as promising injectable long ­ acting contraceptive with minimal risk. This work was planned to evaluate the structural and histochemical changes induced by injectable contraceptive Depo-provera (MPA, on the kidney of adult female Albino rats as well as testing the degree of reversibility of changes that may develop after the arrest of its use. Thirty adult female Albino rats were used in this work and divided into three equal groups. Group I was used as a control, group II was intramuscularly injected with MPA 4 times (2.7 mg / rat every 3 oestrus cycles and sacrificed one day after arrest of the injection, while , group III the animals were injected with MPA by the same dose and sacrificed 30 days after arrest of the injection. The abdominal aorta was exposed and Indian ink injection was injected to study the renal vascular changes. The animals were sacrificed, the kidney was dissected and paraffin sections were prepared and stained by haematoxylin and eosin and PAS technique to study the microscopic structure and the distribution of PAS+ve materials respectively. Frozen sections were prepared and stained by both Gomori and Nachla's techniques to study the activity of acid phosphatase enzyme and succinic dehydrogenase enzyme respectively. The obtained data were statistically analyzed using Student's t.test. The injected groups showed atrophy of tubular epithelium, dilatation of tubular lumina. All recovery groups were nearly similar to normal state except PAS+ve material of renal tubules which were nearly similar to injected groups. The treated groups showed significant increase in vascular distribution and PAS+ve materials. While, non

    International Nuclear Information System (INIS)

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

    Full Text Available Abstract Background White leaf No.1 is a typical albino tea cultivar grown in China and it has received increased attention in recent years due to the fact that white leaves containing a high level of amino acids, which are very important components affecting the quality of tea drink. According to the color of its leaves, the development of this tea cultivar is divided into three stages: the pre-albinistic stage, the albinistic stage and the regreening stage. To understand the intricate mechanism of periodic albinism, a comparative proteomic approach based on two-dimensional electrophoresis (2-DE and mass spectrometry was adopted first time to identify proteins that changed in abundance during the three developmental periods. Results The 2-DE results showed that the expression level of 61 protein spots varied markedly during the three developmental stages. To analyze the functions of the significantly differentially expressed protein spots, 30 spots were excised from gels and analyzed by matrix-assisted laser desorption ionization-time of flight-tandem mass spectrometry. Of these, 26 spots were successfully identified. All identified protein spots were involved in metabolism of carbon, nitrogen and sulfur, photosynthesis, protein processing, stress defense and RNA processing, indicating these physiological processes may play crucial roles in the periodic albinism. Quantitative real-time RT-PCR analysis was used to assess the transcriptional level of differentially expressed proteins. In addition, the ultrastructural studies revealed that the etioplast-chloroplast transition in the leaf cell of White leaf No. 1 was inhibited and the grana in the chloroplast was destroyed at the albinistic stage. Conclusions In this work, the proteomic analysis revealed that some proteins may have important roles in the molecular events involved in periodic albinism of White leaf No. 1 and identificated many attractive candidates for further investigation.

    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.

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

    International Nuclear Information System (INIS)

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

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

    International Nuclear Information System (INIS)

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

  9. Autoradiographic localization of tritiated dihydrotestosterone in the flank organ of the albino hamster

    International Nuclear Information System (INIS)

    In the hamster flank organ, the growth of hair and growth of sebaceous glands are androgen-dependent functions. Although dihydrotestosterone (DHT) is known to be a potent stimulator of flank organ growth, there is no information about localization of DHT receptor sites in this organ. The purpose of this study was to use steroid autoradiography to localize DHT receptors in the hamster flank organ. Because steroid hormones are functional when translocated to nuclear receptors, nuclear localization by autoradiography defines receptor sites. In order to be able to visualize autoradiographic grains from radiolabeled androgens around hair follicles, albino hamsters were studied to avoid confusion between the grains and pigment granules which are abundant in the more common Golden Syrian hamster. Mature male hamsters castrated 24 hours earlier were given tritium-labeled dihydrotestosterone ( [3H]DHT). Using the technique of thaw-mount steroid autoradiography, 4-micron unfixed frozen sections were mounted in the dark onto emulsion-coated glass slides and allowed to develop for 4-6 months. [3H]DHT was found to be concentrated over sebocyte nuclei. The label was present peripherally as well as in differentiating sebocytes. There was no nuclear localization of [3H]DHT in animals pretreated with excessive quantities of unlabeled DHT. Steroid metabolites of [3H] DHT were assessed by thin-layer chromatography in paired tissue samples. Most of the label remained with DHT. Uptake was inhibited in the flank organ of hamsters pretreated with unlabeled DHT

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

    International Nuclear Information System (INIS)

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

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

    Full Text Available The current study examined the attenuating influence of dietary carrot pomace powder (CaPP on hypercholesterolemia and various oxidative stress-associated with biochemical parameters in hypercholesterolemic rats. Thirty two male albino rats weighing 110±10 g were divided into four groups, the first group received the basal diet only and served as (negative control, the second group received the hypercholesterolemic diet and served as positive control, the other groups received hypercholesterolemic diet supplemented with 10%, 20% CaPP for six weeks. The obtained results revealed that groups supplemented with 10% and 20% CaPP significantly decrease total lipid, total cholesterol, triglycerides, low density lipoprotein cholesterol, liver enzymes: alanine aminotransferase, aspartate aminotransferase compared to positive and negative groups. Organs weight, body weight gain significantly decreased compared with positive control. Moreover dietary carrot pomace powder can used to reduce the body weight and reducing hypercholesterolemic complications. In addition, dietary carrot pomace powder serves to improve the blood picture and to reduce the blood glucose level in hypercholesterolemic rats and could use in obese people for body loss. Data of kidney function (Urea record an increase in CaPP 20% level (26.9±2.96 but this increase was non significant with the negative control group (26.6±3.1.

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

    International Nuclear Information System (INIS)

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

    2012-01-01

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

  15. 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

  16. Short term toxicity of strawberry flavor and carmoisine color in male albino rats

    International Nuclear Information System (INIS)

    The objective of this study was to determine the potential toxicity associated with oral administrations of the strawberry flavor and carmoisine color. The tested materials were given to the animals in their drinking water. Biochemical parameters were determined in liver, kidney and brain DNA and RNA contents.Sera was used for liver and kidney functions, lipid profile and thyroid hormones estimation. Histopathological, histochemical and cytophotometric studies were performed in liver and kidney tissues. Equal weights of flavoring and coloring agents were mixed at 0.1% w/v with drinking water. Forty adult male albino rats were assigned to four equal groups, two groups were served as controls and the remaining two groups received standard diet and water containing the tested materials for three and six week. There were no deaths and all the studied parameters were affected in a time dependent manner. Liver DNA contents were significantly decreased, kidney DNA contents tended to increase and brain DNA contents were significantly increased only after 6 weeks of treatment. RNA contents were significantly decreased in liver and brain

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

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

    Clinical efficacy of the widely used anticancer drug cisplatin is limited due to its adverse side effects in normal tissues mediated by oxidative stress. This study was aimed to investigate the protective effects of vetiver acetate oil, Java (VO) against cisplatin-induced toxicity in Swiss albino mice. The ameliorating potential was evaluated by orally priming the animals with VO at doses 5, 10 or 20 mg/kg bw for 7 days prior to cisplatin treatment. Acute toxicity in mice was induced by injecting cisplatin (3 mg/kg bw) intraperitoneally for 5 consecutive days. Significant attenuation of renal toxicity was confirmed by histopathological examination, lowered levels of serum blood urea nitrogen, creatinine and reduced DNA damage. VO also compensated deficits in the renal antioxidant system. VO intervention significantly inhibited DNA damage, clastogenic effects, and cell cycle arrest in the bone marrow cells of mice. Hematological parameters indicated attenuation of cisplatin-induced myelosuppression. Overall, this study provides for the first time that VO has a protective role in the abatement of cisplatin-induced toxicity in mice which may be attributed to its antioxidant activity.

    Full Text Available Trypanosoma cruzi is usually transmitted by contact with the excreta of infected Triatominae; among non-vectorial infections, direct transmission through coitus has been proposed. We investigated this possibility by instilling, through the external meatus of the vagina and the penis of previously anesthetized NMRI albino mice, blood of mice infected with strains isolated from Didelphis marsupialis (opossum, strain CO57, Rattus rattus (rat, strain CO22 and human (strain EP. Some animals were allowed to copulate the same day of the instillation. In other experiments, the strains were inoculated in the scrotum. To determine the effect of immunosuppression, some mice were treated with cyclophosphamide 30 days post-instillation. Controls were instilled orally and ocularly. Vaginal instillation with strain CO22 produced systemic infection with tropism to the heart, skeletal muscle, skin, duodenum, pancreas, ovary and sternum. Scrotal inoculation with strain EP likewise invaded liver, spleen, lung, lymph nodes and urogenital organs; while strain CO57 invaded skeletal and cardiac muscle, pancreas, testis, and vas deferens. Penile infection with strain CO22 was detected by xenodiagnosis. Immunosuppression did not increase parasitemia of vaginally infected mice or controls. Mating did not produce infection. Our results show that contact of blood trypomastigotes of T. cruzi with genital mucosa can produce blood and tissue infections. These results are discussed in relation to reports of frequent experimental tropism of T. cruzi toward urogenital organs.

    Full Text Available Management of Diabetes mellitus is one of the greatest challenges among the developing and developed countries. The use of herbal medicine is steadily growing in the management of various diseases all over the world. The present study has been taken up on a poly herbal formulation -SPHAG, a combination of aqueous extracts of plants Solanum nigrum, Premna corymbosa, Holarrhena pubescens, Alstonia scholaris and Gymnema sylvestre for its hypoglycaemic and antioxidant activity in alloxan induced diabetic Wistar albino rats. The four groups containing 6 animals in each group, like Healthy Control, Disease Control, SPHAG lower dose(250 mg/kg.b.wt. and SPHAG higher dose (500 mg/kg.b.wt. were maintained. The oral administration of SPHAG had showed significant reduction in the glucose level and HbA1C level when compared with Disease Control. Biochemical parameters comprising of liver function and renal function tests had shown improved health status in SPHAG treated groups over Disease Control group. The antioxidant enzymes superoxide dismutase, Glutathione peroxidase levels in blood and tissues including liver, kidney and heart were found to be decreased in the Disease control group. SPHAG treated animals showed significant improvement on the antioxidant enzyme levels and the efficacy is found to be dose dependent. Thus, the present study has demonstrated hypoglycaemic and antioxidant potential of SPHAG in the experimental animals. The synergistic contribution of major phyto-constituents of SPHAG i.e. flavonoids and phenols are expected for its biopotency and efficacy.

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

    Objective:To investigate the effects of different dietary fat and oils (differing in their degree of saturation and unsaturation) on lipid peroxidation in liver and blood of rats. Methods:The study was conducted on 50 albino rats that were randomly divided into 5 groups of 10 animals. The groups were fed on dietary butter (Group I), margarine (Group II), olive oil (Group III), sunflower oil (Group IV) and corn oil (Group V) for 7 weeks. After 12 h of diet removal, livers were excised and blood was collected to measure malondialdehyde (MDA) levels in the supernatant of liver homogenate and in blood. Blood superoxide dismutase activity (SOD), glutathione peroxidase activity (GPx), serum vitamin E and total antioxidant capacity (TAC) levels were also measured to determine the effects of fats and oils on lipid peroxidation. Results: The results indicated that no significant differences were observed in SOD activity, vitamin E and TAC levels between the five groups. However, there was significant decrease of GPx activity in groups IV and V when compared with other groups. The results indicated that feeding corn oil caused significant increases in liver and blood MDA levels as compared with other oils and fats. There were positive correlations between SOD and GPx, vitamin E and TAC as well as between GPx and TAC (r:0.743;P Conclusions:The results demonstrated that feeding oils rich in polyunsaturated fatty acids (PUFA) increases lipid peroxidation significantly and may raise the susceptibility of tissues to free radical oxidative damage.

    The comparative efficacy of albendazole and mebendazole oily suspensions (AOS and MOS) was studied in an experimental model of experimental larval alveococcosis in albino mice. The animals were intragastrically injected with the agents once daily for 40 days on day 35 after intraperitoneal inoculation with E. multilocularis acephalocysts. They were dissected 29 days after treatment termination (103 days following inoculation) and the rate of infestation and viability and the degree of maturity of developed alveococcosis larvocysts (AL) were determined. The AOS and MOS efficiency estimated by the mean mass of AL per animal was 83.3 and 98.1%, respectively; whereas the similar indicator calculated by one largest AL weight per animal found among all the animals in the compared groups was equal to 57.7 and 96.9%, respectively. Under the equal conditions of solubilization in vegetable oil, the biological activity and bioavailability of mebendazole were shown to increase to a much greater extent than those of albendazole. The findings suggest that the use of mebendazole is promising for designing new vegetable oil-based formulations of the agent. PMID:24003516

    The problem of echinococcosis has acquired special urgency in Russia in the last 10 years. The dramatically worse epidemiological situation of echinococcosis in the country is suggested by just frequent cases of cystic echinococcosis in the indigenous population of Moscow and its region, including children. Currently, albendazole that is less toxic than mebendazole remains the drug of choice, However, some authors note that E. granulosus larval cysts are moresusceptible to mebendazole than to albendazole. Both drugs mainly show parasitological activity and have no larvicidal effect particularly in larval alveococcosis. Analysis of the results of chemotherapy, with a group of benzimidazole carbamates for echinococcosis in 6 clinical centers from 5 European countries (Italy, Bulgaria, Romania, Greece, and Turkey) over the past 30 years showed that the evaluation of therapeutic effectiveness was overestimated; thus, 40% of all parasitic larval cysts that were considered dead became active again after, 2 years after the treatment. The original oil micronized mebendazole suspension tested by us in albino mice with late-stage larval cystic echinococcosis showed the properties of a highly effective and safe systemic larvicide that caused prompt death in the entire parasite population in the treated animals even in extreme hyperinvasion when the baseline parasite weight was greater than the host's one.

  9. Radiomodification by Aloe vera leaf extract on skin of Swiss albino mice exposed to gamma radiation

    International Nuclear Information System (INIS)

    The development of effective radioprotectors and radiorecovery drugs is of great importance in view of their potential application during both planned (e.g. radiotherapy) and unplanned (e.g. in nuclear industry, natural background radiation emanating from the earth or other sources) radiation exposure. Over the past 50 years, research in the development of radioprotectors has focused on screening a plethora of chemical and biological compounds. Several synthetic chemical compounds have been tested for protection against radiation. But they have limited use due to inherent toxicity. Herbal medicine is still the mainstay of about 75-80 percent of the world population mainly in the developing nations for primary health care because of better cultural acceptability, better compatibility with the human body and lesser side effects. Thus, natural products offer an alternative to their synthetic counterparts due to low toxicity with no side effects. The present investigation has been an attempt to asses the radioprotective efficacy of Aloe vera leaf extract on biochemical alterations in skin of Swiss albino mice

  10. Effects of split fast neutron doses on the liver cells of albino Swiss mice

    International Nuclear Information System (INIS)

    The effect of neutron doses from a compact D-T neutron generator on the liver cells of adult male and female albino Swiss mice was investigated. Fast neutrons (14.5 MeV) were delivered to the whole body in a single dose or in two, four, six or eight equal doses separated by 3-day intervals. The lowest dose, 100 rem, was given over an exposure time of 6 hours and was then steadily raised to 912 rem over an exposure time of 48 hours. During exposure the neutron flux was controlled by the activation foil technique. The animals were killed for testing after each irradiation. Histological examination of the hepatocytes with a light microscope showed marked degenerative changes only after the longer irradiation periods (24, 36 and 48 h). Electron microscopy showed cytological (cytoplasmic and nuclear) changes in the hepatocytes after only 12 hours' irradiation. Densitometric scans of electron micrographs of control and 12 h-irradiated livers indicated that the control hepatocyte interphase nucleus contains approximately 72% heterochromatin, while the irradiated nucleus contains only 64% heterochromatin.

  11. Rectification of radiation-induced damage in swiss albino mice by aloe vera leaf extracts (AVE)

    International Nuclear Information System (INIS)

    From the time immemorial man has been exposed to ionizing radiation from the environment in which he lives. Radiation protection concepts and philosophy have been evolving over the past several decades. Materials and Methods: The radioprotective of effect of Aloe vera leaf extract (1000 mg/kg b.wt. orally for 15 consecutive days) has been studied against 6 Gy of gamma radiation in the intestine of Swiss albino mice at various post irradiation intervals viz. 12 hours, 24 hours. and 3, 5, 10, 20 and 30 days. Results: Crypt survival, villus length, apoptic cells, mitotic figures and goblet cells in jejunum were studied after irradiation. Irradiation produced a significant decrease in crypt survival, mitotic figures and villus length; whereas goblet and apoptic cells showed a significant increase from sham irradiated animals. The major changes were observed on day 3 after irradiation. AVE pre-treated irradiated animals resulted in a significant increase in the number of crypt cells, mitotic figures and villus length; whereas the counts of apoptic and goblet cells showed a significant decrease from respective control group at all the autopsy intervals. Irradiated animals resulted in the elevation in lipid peroxidation and a reduction in glutathione activity. On contrary, AVE treatment before irradiation caused a significant depletion in lipid peroxidation and elevation in glutathione activity. Conclusion: The present study suggests the possible radioprotective ability of Aloe vera leaf extract

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

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

    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-α (TNF-α 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-α 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.

    Aim: To investigate antioxidant potential of lupeol/mango pulp extract (MPE) in testosterone induced oxidative stress in prostate of male Swiss albino mice. Methods: Oral treatment of lupeol (1 mg/animal) and MPE (1 mL [20% w/v]/animal) was given separately to animals along with subcutaneous injection of testosterone (5 mg/kg body weight)consecutively for 15 days. At the end of the study period, the prostate was dissected out for the determination of reactive oxygen species (ROS) levels, lipid peroxidation and antioxidant enzymes status (catalase, superoxide dismutase,glutathione reductase, glutathione-S-transferase). Results: In testosterone treated animals, increased ROS resulted in depletion of antioxidant enzymes and increase in lipid peroxidation in mouse prostate. However, lupeol/MPE treatment resulted in a decrease in ROS levels with restoration in the levels of lipid peroxidation and antioxidant enzymes. Conclusion: The results of the present study demonstrate that lupeol/MPE are effective in combating oxidative stress-induced cellular injury of mouse prostate. Mango and its constituents, therefore, deserve study as a potential chemopreventive agent against prostate cancer.

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

    Objective: To study the anticancer activities of three schiff bases viz. vanillin thiosemicarbazone, benzophenone thiosemicarbazone and acetophenone thiosemicarbazone against Ehrlich ascites carcinoma (EAC) cells in Swiss albino mice. Methods: Synthesized compounds have administrated into the intraperitoneal cavity of the EAC inoculated mice at two doses. The anticancer activities have studied by monitoring the parameters such as cell growth inhibition, tumor weight measurement, survival time of EAC bearing mice as well as the changes in depleted hematological parameters due to tumorgenesis. All such data have been compared with those of a known standard drug bleomycin at the dose of 0.3 mg/kg (i.p.).Results:It has been found that these bases enhanced life span, reduced average tumor weight and inhibited tumor cell growth of EAC cell bearing mice remarkably. The results were similar in potency to those obtained with bleomycin. It was also found that the depleted hematological parameters (red blood count, white blood count and haemoglobin content) were found to be restored gradually towards normal within few weeks after ceasing the treatment.Conclusions:The compounds can be primarily considered more or less as potent anticancer agents.

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

    International Nuclear Information System (INIS)

    Glyphosate (N-(phosphonomethyl) glycine, C3H8NO5P), a herbicide, used to control unwanted annual and perennial plants all over the world. Nevertheless, occupational and environmental exposure to pesticides can pose a threat to nontarget species including human beings. Therefore, in the present study, genotoxic effects of the herbicide glyphosate were analyzed by measuring chromosomal aberrations (CAs) and micronuclei (MN) in bone marrow cells of Swiss albino mice. A single dose of glyphosate was given intraperitoneally (i.p) to the animals at a concentration of 25 and 50 mg/kg b.wt. Animals of positive control group were injected i.p. benzo(a)pyrene (100 mg/kg b.wt., once only), whereas, animals of control (vehicle) group were injected i.p. dimethyl sulfoxide (0.2 mL). Animals from all the groups were sacrificed at sampling times of 24, 48, and 72 hours and their bone marrow was analyzed for cytogenetic and chromosomal damage. Glyphosate treatment significantly increases CAs and MN induction at both treatments and time compared with the vehicle control (P<.05). The cytotoxic effects of glyphosate were also evident, as observed by significant decrease in mitotic index (MI). The present results indicate that glyphosate is clastogenic and cytotoxic to mouse bone marrow.

    Full Text Available Pathological anxiety is one of the most common mental disorders in humans. Anxiolytic drugs, mostly belonging to the benzodiazepine (BDZ group and serotonergic groups are widely used to treat anxiety. However the clinical uses of these established drugs are associated with lot of adverse effects. Therefore the development of new agent possessing anxiolytic effect with minimal or no adverse effects would be of great importance in the treatment of anxiety related disorders. Very high importance is given to the phytoconstituents by the scientific community for a new anxiolytic agent which is devoid of side effects/ minimal adverse effects. In this research work the ethanolic extract of Tylophora indica (300 mg/kg body weight was administered oral for ten days to Wistar albino rats for screening its anxiolytic effect by using Elevated Plus Maze (EPM and Light Dark Arena (LDA test. The results of our study demonstrated that the ethanolic extract of Tylophora indica has significant anxiolytic activity in EPM and LDA models of anxiety.

  5. Radiation induced cerebellum impairments in Swiss albino mice and its modulation by dietary Prunus domestica

    International Nuclear Information System (INIS)

    To study the biochemical, quantitative histopathological and behavioural changes after 5 Gy whole body irradiation and its modulation by supplementation of Prunus domestica extract (PDE) for 15 consecutive days on male Swiss albino. For this study healthy mice from an inbred colony were divided into five groups: (i) Control; (ii) PDE treated - mice in this group were orally supplemented with PDE (400 mg/kg body weight (bw)/day) once daily for 15 consecutive days; (iii) Irradiated-mice were whole body exposed to 5 Gy irradiated; (iv) PDE + irradiated-mice in this group were orally supplemented PDE for 15 days (once a day) prior to irradiation; and (v) irradiated+PDE -mice in this group were administered PDE orally for 15 days (once a day) consequently after irradiation. Marked radiation induced changes in the amount of cerebellar lipid peroxidation (LPO), glutathione (GSH), protein, superoxide dismutase (SOD), catalase and histopathological changes (molecular layer, granular layer and purkinje cell numbers) could be significantly ameliorated supplementation of PDE prior/post irradiation. Radiation induced deficits in learning and memory were also significantly ameliorated. PDE was found to have strong radical scavenging activity in 2,2-diphenyl-1-picrylhydrazyl (DPPH) and also showed in vitro radioprotective activity. The result of present study showed that prior/post-supplementation of Prunus domestica has radioprotective potential as well as neuroprotective properties against the radiation. (author)

    Full Text Available Aims: To find out the pharmacokinetic and pharmacodynamic drug interaction of carbamazepine, a protype drug used to treat painful diabetic neuropathy with glibenclamide in healthy albino Wistar rats following single and multiple dosage treatment. Materials and Methods: Therapeutic doses (TD of glibenclamide and TD of carbamazepine were administered to the animals. The blood glucose levels were estimated by GOD/POD method and the plasma glibenclamide concentrations were estimated by a sensitive RP HPLC method to calculate pharmacokinetic parameters. Results: In single dose study the percentage reduction of blood glucose levels and glibenclamide concentrations of rats treated with both carbamazepine and glibenclamide were significantly increased when compared with glibenclamide alone treated rats and the mechanism behind this interaction may be due to inhibition of P-glycoprotein mediated transport of glibenclamide by carbamazepine, but in multiple dose study the percentage reduction of blood glucose levels and glibenclamide concentrations were reduced and it may be due to inhibition of P-glycoprotein mediated transport and induction of CYP2C9, the enzyme through which glibenclamide is metabolised. Conclusions: In the present study there is a pharmacokinetic and pharmacodynamic interaction between carbamazepine and glibenclamide was observed. The possible interaction involves both P-gp and CYP enzymes. To investigate this type of interactions pre-clinically are helpful to avoid drug-drug interactions in clinical situation.

  8. Antioxidative and radioprotective potential of rutin and quercetin in Swiss albino mice exposed to gamma radiation

    International Nuclear Information System (INIS)

    The radioprotective potential of bioflavonoid, rutin (RUT) and quercetin (QRT) was investigated in Swiss albino mice exposed to gamma radiation. The radioprotective potential of RUT and QRT was assessed in pre-treatment group of mice followed on radiation-induced changes in glutathione (GSH), glutathione-S-transferase (GST), superoxide dismutase (SOD), catalase (CAT), and lipid peroxidation (LPO) levels were also analyzed. Elevation in the GSH, GST, SOD, CAT, and decreased LPO levels were observed in RUT and QRT pretreated group when compared to the irradiated animals. Furthermore, it was observed that RUT and QRT treatment was found to inhibit various free radicals generated in vitro, viz., 2,2-diphenyl-1-picrylhydrazyl (DPPH), O2, 2,2'-azino-bis(3-ethylbenzothiazoline-6-sulphonic acid) (ABTS)·+, and OH· in a concentration-dependent manner. This study clearly demonstrates the free radical scavenging action of RUT and QRT, indicating that it may have its potential as a radioprotective agent. Furthermore, the presence of a phenolic group in RUT and QRT is known to contribute to scavenging the radiation-induced free radicals and inhibition of oxidative stress. Present findings demonstrate the potential of RUT and QRT in mitigating radiation-induced oxidative stress, which may be attributed to the inhibition of radiation-induced decline in the endogenous antioxidant levels and scavenging of radiation-induced free radicals.

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

    International Nuclear Information System (INIS)

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

  10. Radioprotective role of vitamin E and urea in irradiated albino rats

    International Nuclear Information System (INIS)

    In control rats, the levels of glycogen and pyruvic acid in the forebrain were 217 ± 8 to 226 ± 8 and 17.70 ± 0.60 to l8.00 ± 0.62 μ g/g fresh tissue, respectively. Whole body gamma irradiation at the dose of 7 Gy caused a significant increase in the level of glycogen in the forebrain of albino rats. This increase was about 29%, 47%, 38% and 24% on the 1 st, 3 rd, 7 th and 10 th days post irradiation, respectively. As for pyruvic acid content, a temporary significant increase by about 19% on the 3 rd day post irradiation was observed, while a decrease of 32% and 28% was recorded on the 7th and 10th days after irradiation, respectively. The treatment of rats with intraperitoneal injection of either vitamin E at a concentration of 10 mg/100 g animal body weight, or with urea at 200 mg/100 g body weight pre-irradiation reduced the changes induced by whole body gamma irradiation. 1 tab

    Full Text Available Chronic use of various recreational drugs is leading to drug abuse which is increasingly developed in the modern society among the various populations throughout the world. The present study was conducted to investigate the impact of a few recreational drugs viz., anabolic androgenic steroids (AAS, alcohol and nicotine on male fertility status which was assessed by measuring sperm count in male albino mice. Semen samples were collected from normal, AAS-treated, alcohol-treated and nicotine-treated mice and the sperm count (in millions/ml semen was assessed at regular intervals i.e. on 10th, 20th, 30th, 45th,60th,75th and 90th day of treatment during the experimental period of 90 days. The results showed a significant decrease in the sperm count in AAS-treated, nicotine-treated (p<0.01 and alcohol-treated mice (p<0.05 compared to that of the normal mice. The present study clearly indicates suppression of sperm count on AAS, alcohol and nicotine treatment which may be one of the contributing factors in male infertility.

    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.

    Full Text Available Purpose: To evaluate the potential toxicity of ethanol extract of the medicinal plant Solanum villosum (Mill. Methods: Ethanol extract of S. villosum administered orally at ranges of doses 100, 200, 400, 600 and 800 mg/kg/bw to assess its impact on biochemical indices of Wistar albino rats. Hematological profile, biochemical assays, antioxidant and lipid peroxidation assays were compared between control and experimental animals. An acute toxicity test was performed in rats at different concentration of ethanol extract of S. villosum in order to establish the approximate oral lethal dose (LD 50. Results: No mortality occurred during the two weeks experimental period, in both control and experimental groups. The changes in biochemical parameters were statistically insignificant at p<0.05 levels. The treated rats showed that very less toxic symptoms only after 800 mg/kg/bw. These observations were supported by hematological and liver function markers. Conclusions: The medicinal plant Solanum villosum can be administered orally at a dose range of 200 mg/kg/bw was very effective and without any side effects. Ethanol extract of S. villosum is not toxic and therefore it may be used safely in clinical trials. It is the first documented report about the plant Solanum villosum (Mill in the toxicity assessment study.

    Sea cucumber ( Apostichopus japonicus) is one of the most important aquaculture animals in China. Usually its normal body color is black that fits its living environment. The juvenile individuals obtained by crossing albino sea cucumber segregated in body color. To document the transcriptome difference between albino associating sea cucumber and the control, we sequenced their transcriptomes with RNA-seq. Approximately, 4.790 million (M) and 4.884 M reads, 200 nt in length, were generated from the body wall of albino associating sea cucumber and the control, respectively, from them, 9550 (46.81%) putative genes were identified. In total, 583 genes were found to express differentially between albino associating sea cucumber and the control. Of these differentially expressed genes (DEGs), 4.8% changed more than five-folds. The expression levels of eight DEGs were confirmed with real-time PCR. The changing trend of these DEGs detected with real-time PCR agreed well with that detected with RNA-seq, although the change degree of some DEGs was different. Four significantly enriched pathways were identified for DEGs, which included phagocytosis, Staphylococcus aureus infection, ECM-receptor interaction and focal adhesion. These pathways were helpful for understanding the physiological difference between albino associating sea cucumber and the control.

    Full Text Available 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

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

  1. 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

    Full Text Available Objective: To determine the effect of amlodipine on blood glucose levels through oral glucose tolerance test in normoglycemic albino Rats and the magnitude of its effect on basal v/s glucose induced glycemic value compared to control.Methods: Rats were divided into control and test groups to study the effect of glucose induced glycemic changes in normal rats following oral administration of amlodipine. The control group received 1 ml of distilled water everyday, test group received amlodipine everyday in the dose of 1.5 mg/Kg BW for 3 days.On the third day, 2 hours after drug administration both groups were administered oral glucose in the dose of 0.6 gm/Kg BW. The blood glucose levels were measured at 0, 60 and 150 minutes after glucose administration by rat tail snipping method using ACCUCHEK glucometer.Results: The mean CBG of Test group is significantly higher(P<0.001 at all times of the glucose challenge i.e. 0, 60, 150 minutes from the time of glucose administration compared to control group. The optimal hyperglycemia was seen at 60 minutes which is 32.76% higher than the control group, followed by 0 minutes (29.41% and 150 minutes (7.92%. Conclusion: Amlodipine worsens glycaemic control in normal rats at all hours of glucose challenge. Extending this to human beings, whether with impaired glucose tolerance or overt diabetes mellitus, it is suggested to limit the use of amlodipine to situations unless absolutely necessary since it induces hyperglycaemia even in normoglycaemic rats by a postulated mechanism of inhibition of both basal and glucose induced insulin secretion significantly.

    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.

    Full Text Available Background: Diabetes mellitus is a common endocrine disorder, characterized by hyperglycaemia resulting from defects in insulin secretion, insulin action or both. Ayurvedic herbs are relatively low cost, more suitable and have negligible side-effects than synthetic oral anti-hyperglycaemic agents. Guduchi is reported as highly potent anti-diabetic herb in Ayurveda and Guduchi Ghanavati is popularly known by the Ayurvedic fraternity for its therapeutic properties on Madhumeha represented as diabetes mellitus. Aim: The aim of this study is to evaluate hypoglycaemic and anti-hyperglycaemic activities of Guduchi Ghana (GG in Swiss albino mice. Materials and Methods: Hypoglycaemic and anti-hyperglycaemic potential of GG was evaluated in normal mice using both 18 h fasted mice model and oral glucose tolerance test. GG was suspended in distilled water and administered to animals at the dose of 130 mg/kg. Statistical Analysis: The results were statistically interpreted using Student′s ′t′- test for paired and unpaired data to assess the statistical significance and the significant level was set at P < 0.05. Results: GG showed mild reduction in blood sugar level (BSL at all the time intervals in normoglycaemic mice. In anti-hyperglycaemic activity, glibenclamide at a dose of 0.65 mg/kg studied as the reference standard to compare the potency of test drug. Administration of GG prior to glucose over load resulted significant attenuation in BSL at 60 min, 90 min and 120 min in comparison to glucose control group. Conclusions: GG has mild hypoglycaemic and significant anti-hyperglycaemic activity and can be used in the treatment of diabetes mellitus as well as a supportive drug without fear of producing hypoglycaemia.

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

  6. Protective role of ginseng against gentamicin induced changes in kidney of albino mice

    International Nuclear Information System (INIS)

    Background: Use of gentamicin is now limited due to its toxic effects, mainly on kidney and vestibular system. Herbal products including ginseng has been reported to possess protective effects against drugs induced nephrotoxicity in experimental animals. The current investigation was designed to evaluate the effects of ginseng on gentamicin induced nephrotoxicity. Methods: Eighteen male albino mice of 6-8 weeks age, were divided into 3 groups. Group-A served as control and was given normal mouse diet; Group-B was given 80 mg/Kg/day of gentamicin intraperitoneally dissolved in 1 ml of distilled water for fifteen days. Group-C was given 80 mg/Kg/day of gentamicin intraperitoneally dissolved in 1 ml of distilled water along with 100 mg/Kg/day of ginseng orally dissolved in 1 ml of distilled water, also for fifteen days. At the end of the experiment, blood was drawn from each animal by cardiac puncture for renal function tests. Each animal was then sacrificed and kidneys removed for routine histological studies. Results: In group B, weight of the animals and kidneys decreased and there was significant increase in mean serum urea, creatinine and intraluminal diameter (p<0.001) of proximal convoluted tubules as compared to the controls (group-A). Moderate to severe necrotic and degenerative changes in proximal convoluted tubules were seen in this group. When the Ginseng and gentamicin were given together (group-C), a statistically significant improvement in the mean body and kidney weight along with improvement in renal function tests and tubular diameter were seen (p<0.001). Conclusion: It appears that Ginseng has some protective role against gentamicin induced nephrotoxicity. (author)

    Full Text Available Hyperlipidemia, hyperlipoproteinemia or dyslipidemia is the presence of elevated or abnormal levels of lipids and / or lipoproteins in the blood. Lipid and lipoprotein abnormalities are extremely common in the general population and are regarded as a highly modifiable risk factor for cardiovascular disease due to the influence of cholesterol, one of the most clinically relevant lipid substances in atheroscterosis. Aim of the work: This study aimed to evaluate the possible treatment and protective effect of triphala on hyperlipidemic rats. Material and methods: Six groups (5rat/group of female albino rats (Rattus albinus were used. The 1st group used as control, in the 2nd group hyperlipidemia (25% fat & 2% cholesterol was induced for 3 weeks only then sacrified , the 3rd group was hyperlipidemic rats for 3 weeks then left for other 3 weeks without any additional treatment as a recovery period, the 4th group served as hyperlipidemic group for 3 weeks then treated with triphala for another 3 weeks (25 mg/100 gm b. wt., the 5th group was hyperlipidemic (25% fat & 2% cholesterol for 6 weeks and the 6th group served as hyperlipidemic rats for 6 weeks, and at the same time given triphala (25 mg/100 gm b. wt. by oral administration. Results: The biochemical parameters showed highly significant increase in the body weight, serum glucose, ASAT, ALAT, GGT, LDH, total protein, albumin and total lipids in liver .Many histopathological and histochemical changes were detected in liver tissue of the hyperlipidemic rats. Meanwhile, the treatment with triphala ameliorated the biochemical parameters, histological and histochemical results. Conclusion: It is recommended to use triphala in diets for hyperlipidemic patients or those people who have hyperlipidemic family history.

    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.

    Objective To investigate the effects of different dietary fat and oils (differing in their degree of saturation and unsaturation) on lipid peroxidation in liver and blood of rats. Methods The study was conducted on 50 albino rats that were randomly divided into 5 groups of 10 animals. The groups were fed on dietary butter (Group I), margarine (Group II), olive oil (Group III), sunflower oil (Group IV) and corn oil (Group V) for 7 weeks. After 12 h of diet removal, livers were excised and blood was collected to measure malondialdehyde (MDA) levels in the supernatant of liver homogenate and in blood. Blood superoxide dismutase activity (SOD), glutathione peroxidase activity (GPx), serum vitamin E and total antioxidant capacity (TAC) levels were also measured to determine the effects of fats and oils on lipid peroxidation. Results The results indicated that no significant differences were observed in SOD activity, vitamin E and TAC levels between the five groups. However, there was significant decrease of GPx activity in groups IV and V when compared with other groups. The results indicated that feeding corn oil caused significant increases in liver and blood MDA levels as compared with other oils and fats. There were positive correlations between SOD and GPx, vitamin E and TAC as well as between GPx and TAC (r: 0.743; P<0.001) and between blood MDA and liver MDA (r: 0.897; P<0.001). The results showed also negative correlations between blood MDA on one hand and SOD, GPx, vitamin E and TAC on the other hand. Conclusions The results demonstrated that feeding oils rich in polyunsaturated fatty acids (PUFA) increases lipid peroxidation significantly and may raise the susceptibility of tissues to free radical oxidative damage.

    International Nuclear Information System (INIS)

    Aloe vera is one of the well known medicinal plant and posses a large no. of beneficial bioactive components like Anthraquinone, C-glycosides, anthrones, emodin, acemannan etc. Acemannan (poly-acetylated mannose) is one of the active component present in aloe vera gel and has anticancerous and antimicrobial properties. It has also been reported to have wound healing properties and has role as immunomodulator. The objective of the present study was to evaluate protective efficacy of acemannan against radiation induced damage in in-vitro and in in-vivo using murine splenocytes and Swiss albino mice as a model system. In vitro studies were done using primary mouse splenocytes cultures and effect of radiation on cell proliferation, viability, ROS, DNA damage and apoptosis were studies using MTT, trypan blue, DCFDA, single cell gel electrophoresis and ladder assay respectively. For in-vivo studies mice were pretreated with different doses of drug for 7 days followed by irradiation (5 Gy). Twenty four hours post-irradiation mice was sacrificed to observe the activity of antioxidant enzymes and level of protein expression. Acemannan showed a significant induction of proliferation of splenocytes in radiation treated groups both in in-vitro and in in-vivo. Beside a decrease in radiation induced ROS and DNA damage was observed in in-vitro system. Acemannan treatment was able to reduce the radiation induced apoptosis by about 50% both in in-vitro and in in-vivo. In in-vivo acemannan helps in the restoration of the antioxidant enzyme level (catalase, SOD, DTD and GST) besides maintaining the proper redox status via GSH, in irradiated mice. In our studies a dose of 50 mg/kg body wt of acemannan showed the best protective effects. On the basis of the above results it could be concluded that acemannan may have radioprotective potential.

    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.

    Context Manilkara zapota (L.). P. Royen. (Sapotaceae) has been used in folk medicine to treat pain, diarrhoea, inflammation, arthralgia, and other disorders. Objective Screening of Manilkara zapota leaves ethanol extract and its different solvent soluble fractions for possible antinociceptive and antidiarrhoeal activities in Swiss albino mice. Materials and methods The extract and various fractions (200 and 400 mg/kg body weight; p.o.) were tested for peripheral and central antinociceptive activity by acetic acid-induced writhing and radiant heat tail-flick method, respectively; castor oil-induced diarrhoeal model was used to evaluate antidiarrhoeal activity at both doses. All the samples were administered once in a day and the duration of study was approximately 5 h. Results Ethanol extract (400 mg/kg), petroleum ether fraction (400 mg/kg), and ethyl acetate fraction (400 mg/kg) showed significant peripheral antinociceptive activity having 59.89, 58.24, and 46.7% (p < 0.001) of writhing inhibition, respectively, which is comparable with that of standard diclofenac (59.34% inhibition). The ethanol extract (400 mg/kg) and petroleum ether fraction (400 mg/kg) also showed promising central analgesic activity having 74.15 and 82.15% (p < 0.001) elongation of reaction time, respectively, at 90 min after administration of sample which is also similar to that obtained by morphine (85.84% elongation). In antidiarrhoeal activity screening, ethanol extract (200 and 400 mg/kg) showed significant inhibition of defecation by 53.57 and 60.71%, respectively (p < 0.001) compared with that of loperamide (71.42%). Discussion and conclusion The findings of the studies demonstrated antinociceptive and antidiarrhoeal activities of M. zapota leaves which could be the therapeutic option against pain and diarrhoeal disease.

    Full Text Available Background:Combination analgesics provide more effective pain relief for a broader spectrum of pain. This research examines the possible potentiation of the analgesic effect of different classes of antidepressants when combined with aspirin in thermal model of pain using Albino mice.Methods:Different groups of six animals each were injected intraperitoneally by different doses of aspirin (50, 100, or 200 mg/kg, imipramine (2.5, 7.5, 15 or 30 mg/kg, fluoxetine (1.25, 2.5, 5 or 7.5 mg/kg, mirtazapine (1.25, 2.5, or 5 mg/kg and a combination of a fixed dose of aspirin (100 mg/kg with the different doses of the three antidepressants. One hour later the analgesic effect of these treatments were evaluated against thermally induced pain. All data were subjected to statistical analysis using unpaired Student's t-test.Results:Aspirin had no analgesic effect in thermally induced pain. The three selected antidepressants produced dose dependent analgesia. The addition of a fixed dose of aspirin to imipramine significantly increased the reaction time (RT of the lowest dose (by 23% and the highest dose (by 20%. The addition of the fixed dose of aspirin to fluoxetine significantly increased RT by 13% of the dose 2.5 mg/Kg. Finally, the addition of the fixed dose of aspirin significantly potentiated the antinociceptive effect of the different doses of mirtazapine (RT was increased by 24, 54 and 38% respectively.Conclusion:Combination of aspirin with an antidepressant might produce better analgesia, increasing the efficacy of pain management and reduces side effects by using smaller doses of each drug.

    International Nuclear Information System (INIS)

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

  17. 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

  18. Radioprotective effects of Grewia asiatica in vivo: studies in Swiss albino mice

    International Nuclear Information System (INIS)

    Full text: Increasing use of nuclear radiation for human welfare necessitates a new, safe and cost effective radio protector not only for personnel's charged with responsibility of testing or with radiations in laboratories, but also for the general public. Keeping this view, this study has been undertaken to find out the possible radio protective potential of the Grewia asiatica fruit pulp extract (GAE), Grewia asiatica has a high content of antioxidants like Vitamin C, anthocyanin and folate that may play a possible role in radioprotection. For experimental study, healthy Swiss Albino mice were selected from an inbred colony and divided into four groups. Group I (normal) did not receive any treatment. Group II was orally supplemented (GAE) once daily at the dose of 700 mg/Kg. b.wt/day for fifteen consecutive days. Group III (control) received distilled water orally equivalent to GAE for fifteen days than exposed to 5 Gy of gamma radiation. Group IV (experimental) was administered orally (GAE) for 15 consecutive days once daily after exposure to single dose of 5Gy of gamma radiation. Mice were sacrificed at different autopsy intervals viz. 1, 3, 7, 15 and 30 days and liver was removed for various biochemical estimations viz. glutathione (GSH), lipid peroxidation (LPO). Irradiation resulted an elevation in lipid peroxidation (LPO) and a decline in glutathione (GSH) level in liver. On the other hand, treatment of animals with GAE extract after irradiation caused a significant decrease in LPO and a marked elevation in GSH. This finding showed that post treatment of GAE is more effective than its pretreatment

  19. Haemoprotective effects of Emblica officinalis Linn. against radiation and lead induced toxicity in Swiss albino mice

    International Nuclear Information System (INIS)

    Radiation is known to cause cell death, mainly due to its ability to produce reactive oxygen species in cells. Lead is a serious public health problem in many parts of the world. Emblica officinalis is closely linked to its protective properties against free radicals attack. The hematopoietic system plays an important role in maintaining the vitality of animals. Therefore, the purpose of present study was haemoprotective effects of Emblica officinalis Linn. against radiation and lead induced toxicity in Swiss albino mice. For the study, Animals were divided into seven groups. The Emblica was administered seven days prior to irradiation or lead acetate treatment. The animals were autopsied from all the experimental groups at each post treatment intervals of 1, 2, 4, 7, 14 and 28 days. The value of RBC, WBC, PCV, haemoglobin were found to decrease up to day-14 in non-drug treated groups (II, III and IV), thereafter it increased on day-28. In Emblica treated groups (V, VI and VII) the value decreased up to day-7 then it increased up to day-28. The decrease in values was lesser in Emblica treated groups. The value of MCV also showed an increasing trend. The increase in the value of MCR was lesser in Emblica treated groups as compared to non-drug treated groups. Besides this values of MCRC decreased in all the groups at various intervals but the values were lower in the Emblica treated groups. Thus, it may be concluded that Emblica has the ability of inhibiting oxidative stress and substantially protect blood from radiation and heavy metal toxicity. (author)

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

    International Nuclear Information System (INIS)

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

    The Panax ginseng has been used as traditional medicine for past several years among oriental people. The present investigation has been made to assess the radioprotective efficacy of ginseng root extract in the testicular enzymes of Swiss albino mice. The Swiss albino mice were divided into different groups. Ginseng treated group: The animals were administered 10 mg/kg body weight ginseng root extract intraperitoneal (i.p.). Radiation treated group: The animals were exposed to 8 Gy gamma radiation at the dose rate of 1.69 Gy/min at the distance of 80 cm. Combination group: Animals were administered ginseng extract continuously for 4 d and on 4th day they were irradiated to 8 Gy gamma radiation after 30 min of extract administration. The animals from above groups were autopsied on day 1, 3, 7, 14 and 30. Biochemical estimations of acid and alkaline phosphatases and Lipid peroxidation (LPO) in testes were done. In ginseng treated group acid and alkaline phosphatases activity and LPO level did not show any significant alteration. In irradiated animals there was a significant increase in acid phosphatase activity and LPO level. However, significant decline in alkaline phosphatase activity was observed. The treatment of ginseng before irradiation causes significant decrease in acid phosphatase and LPO level and significant increase in alkaline phosphatase activity. One of the cause of radiation damage is lipid peroxidation. Due to lipid peroxidation, lysosomal membrane permeability alters and thus results in release of hydrolytic enzymes. So, an increase in acid phosphatase was noticed after radiation treatment. The alkaline phosphatase activity is associated with membrane permeability and different stages of spermatogenesis. Due to membrane damage and depletion of germ cells of testes after irradiation the enzyme activity was decreased. Ginseng markedly inhibits lipid peroxidation. It acts in indirect fashion to protect radical processes by inhibition of initiation of

    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.

    A polyculture of taimen Hucho taimen and Albino rainbow trout Oncorhynchus mykiss was conducted at different stocking ratios(4:1, 2:1, 1:1, 1:2, and 1:4) at water temperature of 7.5~10.6℃and dissoluble oxygen level of 6.24~8.69mg/L in order to optimize the cultivation model of taimen and albino rainbow trout. The result showed that the polyculture of taimen with albino rainbow trout at a proper ratio resulted in increase in survival rate of taimen. However, the survival rate of albino rainbow trout was found to be decreased in the polyculture of albino rainbow trout with taimen. The total survival rate was decreased as the increase in ratio of taimen in both polyculture of taimen with Albino rainbow trout and polyculture of albino rainbow trout with taimen. As high as survival rate of 90.56%and weight gain rate of 979.87%and 1124.18%were observed at a ratio of 200:100 and 150:150 in the polyculture of taimen with albino rainbow trout, in which the growth of albino rainbow trout was not significantly influenced by taimen (P>0.05), though the predation and behavior of both taimen and albino rainbow trout were affected by the polyculture. During the whole experiment, the variation coef-ficients of body length and body weight in both taimen and albino rainbow trout were manifested the same change trend, the variation coefficients of body length and body weight in albino rainbow trout being increased as increase in the ratio of taimen.%在水温7.5~10.6℃、溶氧6.24~8.69mg/L条件下,进行不同比例(4:1、2:1、1:1、1:2、1:4)的哲罗鲑Hucho taimen与日本金鳟Oncorhynchus mykiss混养试验,以优化哲罗鲑与日本金鳟的养殖模式。结果表明:哲罗鲑养殖过程中,混养适当比例的日本金鳟可以有效地提高哲罗鲑的存活率,而日本金鳟养殖中混养哲罗鲑对日本金鳟的存活有一定抑制;各混养组鱼的存活率随哲罗鲑比例的增大而降低。哲罗鲑养殖中,混养一定

    Full Text Available Abstract Background Skin cancers are a major risk associated with albinism and are thought to be a major cause of death in African albinos. The challenges associated with the care of these patients are numerous and need to be addressed. The aim of this study was to outline the pattern and treatment outcome of skin cancers among albinos treated at our centre and to highlight challenges associated with the care of these patients and proffer solutions for improved outcome. Methods This was a retrospective study of all albinos with a histopathological diagnosis of skin cancer seen at Bugando Medical Centre from March 2001 to February 2010. Data collected were analyzed using descriptive statistics. Results A total of 64 patients were studied. The male to female ratio was 1.5:1. The median age of patients was 30 years. The median duration of illness at presentation was 24 months. The commonest reason for late presentation was financial problem. Head and the neck was the most frequent site afflicted in 46(71.8% patients. Squamous cell carcinoma was the most common histopathological type in 75% of cases. Surgical operation was the commonest modality of treatment in 60 (93.8% patients. Radiotherapy was given in 24(37.5% patients. Twenty-seven (42.2% of the patients did not complete their treatment due to lack of funds. Local recurrence following surgical treatment was recorded in 6 (30.0% patients. Only thirty-seven (61.7% patients were available for follow-up at 6–12 months and the remaining patients were lost to follow-up. Conclusions Skin cancers are the most common cancers among albinos in our environment. Albinism and exposure to ultraviolet light appears to be the most important risk factor in the development of these cancers. Late presentation and failure to complete treatment due to financial difficulties and lack of radiotherapy services at our centre are major challenges in the care of these patients.

    The effects of isosaline extracts of Tetrapleura tetrapetra and Olax subscorpioides were investigated in albino rats. The treatment of rats with these extracts resulted in an increase in the activities of serum alanine aminotransferase, liver aspartate aminotransferase, alanine aminotransferase, acid phosphatase and alkaline phosphatase. The extract of Tetrapleura tetrapetra caused a significant increase in blood glucose and liver glycogen levels while the extract of Olax subscorpioides caused a slight reduction but not statistically significant in the levels of blood glucose and liver glycogen. Both extracts exhibited a significant reduction of protein in the livers of treated rats. PMID:21214460

    Sea cucumbers Apostichopus japonicus are one of the most important aquaculture species in China. Their normal body color is black to fit their surroundings. Wild albinos are rare and hard to breed. To understand the differences between albino and normal (control) sea cucumbers at the transcriptional level, we sequenced the transcriptomes in their body-wall tissues using RNA-Seq high-throughput sequencing. Approximately 4.876 million (M) and 4.884 M 200-nucleotide-long cDNA reads were produced in the cDNA libraries derived from the body walls of albino and control samples, respectively. A total of 9 561 (46.89%) putative genes were identified from among the RNA-Seq reads in both libraries. After filtering, 837 significantly differentially regulated genes were identified in the albino library compared with in the control library, and 3.6% of the differentially expressed genes (DEGs) were found to have changed those more than five-fold. The expression levels of 10 DEGs were checked by real-time PCR and the results were in full accord with the RNA-Seq expression trends, although the amplitude of the differences in expression levels was lower in all cases. A series of pathways were significantly enriched for the DEGs. These pathways were closely related to phagocytosis, the complement and coagulation cascades, apoptosis-related diseases, cytokine-cytokine receptor interaction, and cell adhesion. The differences in gene expression and enriched pathways between the albino and control sea cucumbers offer control targets for cultivating excellent albino A. japonicus strains in the future.

    Full Text Available Hypericum triquetrifolium aqueous extract were studied for the first time for its toxic and the possible clastogenic effects in vivo on the bone marrow and spermatozoa cells of Swiss albino mice. The lethal dose of the aqueous extract was considered to be 10.33 g/kg of the body weight, injected subcutaneously. The doses which were chosen for treatments were 2, 1, and 0.25 g/kg. H. triquetrifolium extract induce statistically significant increases in the average numbers of micronucleus(MN at the dose 2 g/kg and chromosome aberrations at the doses 2 and 1 g/kg ,the majority of aberrations observed were chromatid breaks, centromeric breaks, acentric fragments. The extract was found to inhibit mitotic index (MI in a dose-dependent manner. Moreover the plant extract showed a significant induction of sperm abnormalities in all concentrations used comparing with the untreated animals. The most frequent types of sperm abnormalities of the treated groups were; amorphous, pseudo-droplet defect, bent mid piece defect and corkscrew mid piece defect. However, the lowest dose 0.25 g/kg body weight was the most effective one which markedly increased the corkscrew midpiece defect. The results indicated that the mixture of the compounds found in the aqueous extract caused cytotoxicity and induced different cytogenetic effects in both somatic and germ cells of male albino mice.

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

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

    Full Text Available Objective : The main objective of the present study was to explore the antitumor activity of the ethyl acetate extract of the Alternanthera brasiliana (EAAB and its antioxidant status against Ehrlich ascites carcinoma (EAC in Swiss albino mice. Materials and Methods: Based on the preliminary in vitro cytotoxicity studies, EAAB was selected for anti-tumor and antioxidant effects. Anticancer activity of EAAB was evaluated against EAC in Swiss albino mice at the doses of 200 and 400 mg/kg. EAAB was administered for 14 consecutive days after induction of cancer. After 24 h of the last dose and 18 h of fasting, half of the mice were sacrificed and rest were kept alive for assessing any increase in life span. The antitumor effect of EAAB was assessed by evaluating tumor volume, viable and nonviable tumor cell count, tumor weight, hematological and biochemical parameters of EAC bearing host. Furthermore, the antioxidant and histopathological parameters were evaluated. Results: EAAB treatment has shown significant decrease in tumor volume, viable cell count, tumor weight and elevated the life span of EAC tumor bearing mice in a dose dependent manner. In hematological profile count of RBC, hemoglobin, and WBC were found reverted to normal. EAAB also significantly decreased the levels of lipid peroxidation and significantly increased the levels of GSH, SOD and Catalase. Conclusion: From the above results it may be concluded that EAAB has potent dose dependent antitumor activity and is comparable to that of 5-flourouracil.

    Gentamicin is an aminoglycoside isolated from Micromonospora purpurea known for its nephrotoxicity. Ficus carica L is known to treat many ailments. This study was designed to investigate the effects of Ficus carica L. (Anjir) leaf extract on renal oxidative stress induced by gentamicin in albino mice. Methods: In this laboratory based experimental study 30 mice were divided into three groups, containing 10 mice each. Group A being the control; groups B and C were experimental and treated with gentamicin 200 mg/kg/day intraperitoneally and, Ficus carica L. leaf extract 400 mg/kg/day orally with gentamicin 200 mg/kg/day intraperitoneally respectively for a period of 8 days. Blood samples were taken 24 hours after completion of the experimental period by cardiac puncture under anesthesia and kidneys of each mouse were taken out for microscopic examination. Results: Gentamicin treatment increased serum urea and creatinine levels (group B). Ficus carica L. leaf extract treated animals showed significant reduction in biochemical markers of kidney functions in group C. The histopathological examination of group A showed normal renal structure which was deranged in group B treated with only gentamicin, whereas, group C exhibited marked improvement in histological structure. Conclusion: Ficus carica L. leaf extract is effective in preventing gentamicin induced functional and structural changes in kidney of albino mice. (author)

    Aqueous extract of Cochlospermum planchonii Hook. Ef. x Planch rhizome was investigated for its toxic effects in albino rats using some liver and kidney functional indices as 'markers'. Thirty six albino rats weighing 200.08 ± 10.21 were randomly assinged into six groups (A-F) of six animals each. Animals in groups A-E were orally administered on daily basis with 1 ml of the extract corresponding to 50 mg/kg body weight of the extract for 1, 3, 5, 10 and 15 days while those in the control group received orally 1 ml of distilled water. Rats in all the groups were sacrificed 24 hours after the completion of their respective doses. The extract significantly (P0.05) with the control value. There was no effect (P>0.05) on the acid phosphatase activity of the tissues and serum of the animals. The extract also reduced the urea, albumin and creatinine content in the serum of the animals. The alterations in the biochemical parameters by the aqueous extract of Cochlospermum planchoni may have consequential effects on the normal functioning of the liver and kidney of the animals. Therefore, the 50 mg/kg body weight of the aqueous extract of Cochlospermum planchoni rhizome may not be completley safe as an oral remedy. PMID:22238479

    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.

  7. Protective effect of lycopene on whole body irradiation induced liver damage of Swiss albino mice: pathological evaluation

    International Nuclear Information System (INIS)

    The present study was aimed to evaluate the radioprotective efficacy of lycopene, a naturally occurring dietary carotenoid on whole body radiation-induced liver damage of Swiss albino mice. The first phase of the study was carried out to fix the effective concentration of Iycopene by performing a 30 days survival studies using different graded doses (10, 20, 40 and 80 mg/kg body weight) of lycopene administered orally to mice via intragastric intubations for seven consecutive days prior to exposure of whole body radiation (10 Gy). Based on the results of survival studies, the effective dose of Iycopene was fixed which was then administered to mice orally via intragastric intubations for seven consecutive days prior to exposure of whole body radiation (4 Gy) to evaluate its radioprotective efficacy by performing various biochemical assays in the liver of Swiss albino mice. The results indicated that radiation-induced decrease in the activities of endogenous antioxidant enzymes and increase in lipid peroxidative index, DNA damage and comet assays were altered by pre-administration with the effective dose of Iycopene (20 mg/kg body weight) which restored the antioxidant status to near normal and decreased the levels of lipid peroxidative index, DNA damage and comet assays.These results were further confirmed by histopathological examinations which indicated that pre-administration with the effective dose of Iycopene reduced the hepatic damage induced by radiation.

    Bisphenol A (BPA) is a synthetic oestrogen that is extensively used in a wide range of daily used plastic products. This makes it one of the environmental chemicals that may have impact on human health. Due to its oestrogenic effect, BPA might affect the mammary gland. This study aimed to investigate the influence of BPA on the histological structure of the mammary gland of the adult female albino rat and its effect on epithelial cell proliferation and apoptosis status, in addition to its possible modulating effect on estrogen receptor expression. Thirty female adult albino rats were divided into control and experimental groups. The rats in the experimental group were gavaged with 5 mg/kg BPA daily for 8 weeks. The mammary glands were dissected and processed for histological and immunohistochemical stains for Ki-67, activated caspase-3 and estrogen receptor alpha (ER-α). BPA induced an increase in the number and size of the acini and ducts in the mammary gland of treated rats with hyperplasia of their lining epithelial cells. The collagen fibre content was significantly increased in the connective tissue stroma separating the ducts. Immunohistochemical results showed a significant increase in Ki-67 and caspase-3, but a non-significant increase in ER-α expression. Bisphenol A induced structural changes and affected the proliferation rate of mammary glands, so it might be one of the predisposing factors for breast cancer. PMID:26877094

    Full text: The aim of the present study was to evaluate the radioprotective effect of Grewia asiatica fruit pulp extract (GAE) on Swiss albino mice exposed to gamma radiation. In the present study radioprotective efficacy of Grewia asiatica (rich in anthocyanin, carotenes, Vit.C, etc.) was studied against radiation induced biochemical alterations in mice cerebrum. For experimental study, healthy Swiss Albino mice were selected from an inbred colony and divided into four groups. Group I (normal) did not receive any treatment. Group II was orally supplemented (GAE) once daily at the dose of 700 mg/Kg.b.wt/day for fifteen consecutive days. Group III (control) received distilled water orally equivalent to GAE for fifteen days than exposed to 5 Gy of gamma radiation. Group IV (IR+Drug) was administered orally (GAE) for 15 consecutive days once daily after exposed to single dose of 5Gy of gamma radiation respectively. Mice were sacrificed at different autopsy intervals viz. 1, 3, 7, 15 and 30 days and cerebrum were removed for various biochemical estimations viz. glutathione (GSH), lipid peroxidation (LPO) and protein. GAE post treatment renders protection against various biochemical changes in mice cerebrum. Radiation induced augmentation in the levels of LPO was significantly ameliorated by GAE post-treatment. Radiation-induced depletion in the level of GSH, protein was checked significantly by GAE administration

  10. Genotoxic and biochemical effects of Yohimbe after short-term treatment in somatic and germ cells of Swiss Albino Mice

    International Nuclear Information System (INIS)

    Yohimbe was evaluated for its effects on cytological and biochemical toxicity in male Swiss albino mice. Adult male mice were mice were treated with different doses (750, 1500 and 3000 mg yohombe/kg., body weight/day) in form of an aqueous suspension for 7 consecutive days by gavage. The following parameters were evaluated: (i) cytological studies on micronucleus test, (ii) cytological analysis of spermatozoa abnormalities, (iii) Cytogentic analysis of meiotic chromosomes in the tests, (iv) quantification of proteins, ribose nucleic acid (RNA) and deoxyribose nucleic acid (DNA) in hepatic and testicular cells and (v) estimation of malondialdehyde (MDA) and nonprotein sulfhydryl (NP-SH) in hepatic and testicular cells. The treatment caused significant changes in the frequency of micronuclei in the femoral cells and induced spermatozoal abnormalities and testicular chromosomal aberrations. The study on biochemical parameters showed an increase of MDA and depletion of NP-SH, proteins, RNA and DNA in both hepatic and testicular cells. The data elucidated the role of free radical species in cytological and biochemical changes in both somatic and germ cells of Swiss albino mice. The exact mechanism of the genesis of lipid peroxides is not known, however, this might be related to the influence of yohimbine (the principal constituent of yohimbe) to enhance some catecholamines, including norepineprine which possess destructive stimuli on biological systems. It is suggested that, in view of the observed cytological and biochemical effects of yohimbe, it may be subjected to a thorough evaluation of toxicity before making it available for human use.

  11. Protective efficacy of Aloe vera against radiation and cadmium induced haematological changes in the Swiss Albino mice

    International Nuclear Information System (INIS)

    The aim of the present study was to evaluate the protective effect of Aloe vera against radiation and cadmium induced haematological changes in the Swiss albino mice; 6-8 weeks old animals from each of the experimental groups were sacrificed by cervical dislocation at each post treatment intervals of 1,2,4,7,14 and 28 day. After sacrificing the animals, the blood was collected by cardiac puncture in heparinized tubes for various haematological studies. The values of RBC, WBC, Haemoglobin and PCV were found to decrease up to day-14 in non drug treated groups (II,III and IV), thereafter they increased on day-28. Whereas the values decreased upto day-7 in Aloe vera treated groups (V,VI,VlI) thereafter increased tip to day-28. On the other hand, the value of MCV increased upto day- 14 in non-drug treated groups (II, III, IV) and tip to day-7 in drug treated groups (V, VI, VII), thereafter it decreased tip to day-28. After combined treatment of radiation and cadmium chloride synergistic effects were observed. The Aloe vera treated animals exhibited less severe damage as compared to non-drug treated animals at all the corresponding intervals. An early and fast recovery was noticed in Aloe vera pretreated animals. Thus, it appears that Aloe vera is potent enough to check cadmium and radiation induced haematological changes in the Swiss albino mice. (author)

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

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

    Full Text Available 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.

    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

    International Nuclear Information System (INIS)

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

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

  5. Preventive action of Aloe vera against radiation and cadmium induced haematological changes in Swiss albino mice

    International Nuclear Information System (INIS)

    Haematopoietic organs are markedly sensitive to ionizing radiation due to its proliferate activity. The changes found in the circulating blood are primarily due to damage in the radio sensitive haematopoeitic organs. A very small dose of radiation to a blood forming organ causes an arrest of haematopoiesis with changes in peripheral blood count. Certain trace elements are essential for normal growth and development of organisms but their concentration beyond threshold may produce damage to blood forming organs and tissues thus affecting the peripheral blood. Aloe vera has been claimed to contain several important therapeutic properties including anti cancer effects. Various studies showed the prevention of radiation induced suppression of immunity by Aloe vera components. Having these unique properties, Aloe vera could be used in clinical field as a protector against radiation and heavy metal toxicity in human beings. For the study, six to eight weeks old Swiss albino mice were procured and kept in polypropylene cages. The animals were fed with standard mice feed and water was provided to them ad libitum. Cadmium chloride was administered orally to the animals in drinking water at the dose rate of 20 ppm. The animals were exposed to sub lethal doses of 2.0 Gy and 4.0 Gy of gamma radiation from cobalt60 source. The Aloe vera was given seven days prior to irradiation and continued up to last autopsy day in experimental animals. Five animals from each group were autopsied by cervical dislocation at each post treatment interval of 1,2,4,7,14 and 28 days. The differential leucocytes count was estimated by preparing smear of the blood. The value of lymphocyte decreased up to day-14 in non drug treated groups thereafter it increased up to day-28 whereas the count decreased up to day-7 in drug treated groups and showed an increasing trend at day-14 which continues up to day-28. The value of monocyte and granulocyte percentage increased up to day-7 in drug treated groups

    Purpose: To evaluate the effect of intravitreal azithromycin on the retina in a newborn rabbit model. Methods: Twelve, two-week old New Zealand albino rabbits were divided into two groups (six in each). The right eyes of six rabbits received 0.75 mg (0.05 mL) azithromycin and the right eyes of the remaining six rabbits 1.5 mg (0.1 mL) azithromycin intravitreally. Left eyes were served as the control and received the same volume of saline. All eyes were enucleated at the third postinjection week. Retinal histology was examined by light microscopy. Apoptosis of the retinal cells was further evaluated by immunohistochemical staining for caspase-3 and in situ terminal deoxynucleotidyl transferase-mediated biotin-deoxyuridine triphosphate nick-end labeling (TUNEL) of DNA fragments. Results: Light microscopy demonstrated no retinal abnormalities in all eyes. However, retinal nuclear DNA fragmentation was evident in both study groups (33.6% with 1.5 mg and 21.4% with 0.75 mg azithromycin) with the TUNEL method. TUNEL staining ratio was statistically higher only in the second group treated with 1.5 mg azithromycin when compared to the control group (p=0.01 Mann Whitney U test). The ratio of caspase-3 positive cells in the two study groups was 21.5% and 20.2%, respectively. Caspase-3 staining ratio was statistically higher in both study groups when compared to the control eyes (p=0.00, p=0.00 respectively). The difference of TUNEL staining ratio between the two study groups was statistically significant (p=0.028), but there were no statistically significant differences in the two study groups by caspase-3 staining (p=0.247). Conclusion: In newborn rabbits, intravitreal azithromycin injection resulted in an apoptotic activity in the photoreceptor, bipolar and ganglion cells. Immunohistochemical analysis suggested that doses of 0.75 mg and 1.5 mg azithromycin, administered intravitreally might be toxic to the newborn rabbit retina. PMID:27014381

    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

    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

  12. Impairment of adrenal Gland in albino rat embryo in response to polytrin contamination and/or whole body gamma irradiation

    International Nuclear Information System (INIS)

    In the present work, investigations have been carried out in view of evaluation of the biological hazard exerted on adrenal gland of albino rat embryos subjected to the pesticide polytrin and whole body gamma irradiation either individually or in succession. Histological and histochemical studies showed in general, vacuolation, karyolysis, pyknotic nuclei and increased signs of necrosis in adrenal tissue exposed to irradiation. Pesticide treatment resulted in severe degeneration in between zona glomerulosa and fasciculata accompanied by intercellular degeneration. Combined effect of polytrin together with gamma irradiation showed to exert more intensive degeneration in tissue cells with affected chromatin material as compared with the effect of either polytrin or irradiation when applied individually. The histochemical investigations revealed decreased alkaline phosphatase activity in all treated groups. 14 figs

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

    The incidence of trichinosis in Russia was 0.07 per 100,000 population in 2014, which was 2.9-fold higher than that in 2013. Two WHO recommended medications mebendazole and albendazole are now used to treat humari trichinosis. The drugs are active against only mature helminths and non-encysted muscle larvae. The original oil suspension of micronized mebendazole was.found to have 100% efficacy against trichinosis in albino mice in the late muscular phase (encysted larvae) of hyperinvasion after intensive therapy under lifetime diagnostic guidance during and after a treatment cycle. The lifetime diagnostic method used to evaluate the larvicidal activity of anti-trichinosis agents in animals with experimental trichinosis revealed the signs of viaility, established a trend for deatih of Trichinella larvae, and determined their destructive changes.

    International Nuclear Information System (INIS)

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

    International Nuclear Information System (INIS)

    Whole body exposure to ionizing radiation provokes oxidative damage, organ dysfunction and metabolic disturbance. Herbal drugs offer an alternative to the synthetic radioprotective compounds which are either non-toxic or less toxic. Aloe vera rich in polyphenolic compound is known to possess antioxidant properties. In the context, the present study, effect of Aloe vera against radiation and cadmium induced changes in the brain of Swiss albino mice. For the purpose, six to eight weeks old male Swiss albino mice were selected and divided into seven groups:- Group I (Sham-irradiated), Group II (treated with cadmium chloride 20 ppm), Group III (Irradiated with 7.0 Gy gamma rays), Group IV (Both irradiated and treated with cadmium chloride solution), Group V (Cadmium and Aloe vera treated), Group VI (radiation and Aloe vera treated), Group VII (radiation, and cadmium chloride and Aloe vera treated). The animals were sacrificed by cervical dislocation at each post-treatment intervals of 1, 2, 4, 7, 14 and 28 days. The brain (cerebral cortex) was taken out and quantitatively analyzed for different biochemical parameters such as total proteins, glycogen, cholesterol, acid phosphatase activity, alkaline phosphatase activity, DNA and RNA. The value of cholesterol, glycogen, RNA, acid phosphatase activity, and alkaline phosphatase activity increased up to day-14 in non drug-treated groups and day-7 in Aloe vera treated groups and thereafter decreased up to day-28. The value of total proteins and DNA decreased up to day-14 in non drug-treated groups and day-7 in the drug treated groups then increased in all groups. In only cadmium chloride (Without and with drug) treated animals (Groups II and V) the value of cholesterol decreased during early intervals (days-14 and 7 respectively) and increased thereafter. Severe changes were observed after combined exposure to radiation and cadmium chloride showing synergistic effect. Aloe vera reduced the severity of damage and made the

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

    International Nuclear Information System (INIS)

    Ionizing radiation kills cells in the area being treated (the target tissue) as well as other surrounding healthy cells. The damaging effects of ionizing radiation on healthy tissue create a major barrier in effective treatment of common human cancers. Thus there is a need to find a safe and highly effective avenue to reduce normal cell damage during cancer therapy, plants have been used in the traditional healthcare system from time immemorial, and phyto products continue to play an essential role in medicine. Emblica, is reported to have an excellent radio protective activity, antioxidant and a free radical scavenger. In light of above, the present study was aimed to evaluate the protective effect of Emblica against radiation and lead induced biochemical alterations in the kidney of Swiss albino mice. The animals were exposed to 6.0 Gy of gamma rays with or without Lead acetate treatment. The Emblica was administered seven days prior to irradiation or Lead Acetate treatment. The animals from all experimental groups were sacrificed by cervical dislocation at each post treatment intervals of 1, 2, 4, 7, 14 and 28 days. After sacrificing the animals, pieces of the kidney were taken out and kept at - 20 deg C for different biochemical parameters. For the study the animals were exposed to 6.0 Gy of gamma rays with or without Lead acetate treatments. In the experimental groups the Emblica juice was given seven days prior to the radiation or lead acetate treatment. The various biochemical parameters viz, total proteins, glycogen, cholesterol, acid phosphatase and alkaline phosphatase activities, DNA and RNA were estimated. The values were observed in the form of increase or decrease. After combined treatment of radiation and lead acetate the changes were more severe showing synergistic effect of both the agent. An early and fast recovery was also noticed in Emblica pre-treated animals. Thus it appears that Emblica is potent enough to check Lead and Radiation induced

    The vast potential of radiant energy opens vistas of new horizons as its use in various fields of science, technology, therapeutics and diagnosis. However its also exposes the global population to the hazards of nuclear accidents and radiation injury. In this era of nuclear science it has become a prerequisite to know the effects of radiation on mankind and to develop effective countermeasures for minimizing the damages of radiation exposure. Heavy metals like lead can cause deleterious effects when its concentration goes beyond the limit in ecosystem. The combined effects of radiation and lead further increases the causation of damages to organs and tissues. Amla is found to be a non toxic, inexpensive, easily available herbal drug. Therefore present study was pertain to evaluate the chemo preventive role of Amla against radiation and lead induced changes in blood of Swiss albino mice. The animals were exposed to 6.0 Gy of gamma rays and with or without lead acetate which was given to them adlibitum. The Emblica was administered seven days prior to irradiation or lead acetate treatment. Three animals were sacrificed from all the experimental group at each post treatment intervals of 1, 2, 4, 7, 14 and 28 days by cervical dislocation . The blood was collected in heparinised tube for estimating various haematological parameters. The value of RBC, WBC, PCV, Hemoglobin, and MCV decreased up to day-14 in non drug treated groups and day-7 in drug treated groups, thereafter the value increased. When the animals treated with radiation and lead simultaneously synergistic effects were observed. The Amla treated groups showed early and fast recovery thus, it may deduce from above observation that Amla has potential to check the alteration produced by radiation and lead in the blood of Swiss albino mice.

  11. Protective effect of Emblica against radiation and cadmium induced histopathological changes in the brain of Swiss albino mice

    International Nuclear Information System (INIS)

    In the present study six to eight weeks old male Swiss albino mice were exposed to 2.0 and 4.0 Gy of gamma rays with or without cadmium chloride treatment. The animals of experimental groups were administered Emblica for seven days prior to radiation or cadmium chloride treatment. After routine procedure of histology the histopathological changes were observed in the brain of Swiss albino mice. The histopathological changes observed were pycnotic nuclei and crenated cells with condensation of nuclear material resulting into hyperchromatic cells. Hydrocephaly with enlarged lateral ventricles was also noted. Corpus callosum was seen malformed. Thickened meninges and venous congestion were also noticed. In the irradiated brains cytoarchitectonic layers were reduced in depth and showed some degree of intermixing of cells of various laminae. Hematoma was present between the cortex and medulla with numerous pycnotic and necrotic nuclei. Disarray of the cortical tissue with disorientation of cell processes was also evident. Damage in the cortex was noticed in the form of karyolysis, pycnosis and spongy degeneration of the connective tissue with the thickening of meninges. Dilation of blood vessels was also observed at certain places. Quality of these changes remaining the same, but their magnitude increased with dose. With an increase in the dose, time of the onset of recovery is delayed and the time required for complete recovery is longer. After the combined exposure of gamma rays and cadmium chloride, the histological changes were similar but showed higher magnitude than the individual exposure of gamma rays and cadmium chloride. The brain of Emblica treated animals exhibited less severe damage as compared to non-drug treated animals at all the corresponding intervals. An early and fast recovery was also noticed in Emblica pretreated animals. (author)

  12. 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

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

    In this study, we report the biosynthesis of silver nanoparticles using the ethanolic leaf powder extract of Premna serratifolia L. and its anticancer activity in carbon tetra chloride (CCl4)-induced liver cancer in Swiss albino mice (Balb/c). The synthesized silver nanoparticles were characterized by SEM, FTIR and XRD analyses. The Debye-Scherrer equation was used to calculate particle size and the average size of silver nanoparticles synthesized from P. serratifolia leaf extract was 22.97 nm. The typical pattern revealed that the sample contained cubic structure of silver nanoparticles. FTIR analysis confirmed that the bioreduction of silver ions to silver nanoparticles is due to reduction by capping material of the plant extract. The silver nanoparticles of P. serratifolia leaf extract were effective in treating liver cancer in Swiss albino mice when compared with P. serratifolia leaf extract with isoleucine.

    Single nucleotide mutations (SNMs) are associated with a variety of human diseases. The CRISPR/Cas9 genome-editing system is expected to be useful as a genetic modification method for production of SNM-induced mice. To investigate whether SNM-induced mice can be generated by zygote microinjection of CRISPR/Cas9 vector and single-stranded DNA (ssDNA) donor, we attempted to produce albino C57BL/6J mice carrying the Tyr gene SNM (G291T) from pigmented C57BL/6J zygotes. We first designed and constructed a CRISPR/Cas9 expression vector for the Tyr gene (px330-Tyr-M). DNA cleavage activity of px330-Tyr-M at the target site of the Tyr gene was confirmed by the EGxxFP system. We also designed an ssDNA donor for homology-directed repair (HDR)-mediated gene modification. The px330-Tyr-M vector and ssDNA donor were co-microinjected into the pronuclei of 224 one-cell-stage embryos derived from C57BL/6J mice. We obtained 60 neonates, 28 of which showed the ocular albinism and absence of coat pigmentation. Genomic sequencing analysis of the albino mice revealed that the target of SNM, G291T in the Tyr gene, occurred in 11 mice and one founder was homozygously mutated. The remaining albino founders without Tyr G291T mutation also possessed biallelic deletion and insertion mutants adjacent to the target site in the Tyr locus. Simple production of albino C57BL/6J mice was provided by C57BL/6J zygote microinjection with px330-Tyr-M DNA vector and mutant ssDNA (G291T in Tyr) donor. A combination of CRISPR/Cas9 vector and optional mutant ssDNA could be expected to efficiently produce novel SNM-induced mouse models for investigating human diseases. PMID:24879364

    Full Text Available The experiment was conducted to determine the effects of varying levels of rice bran supplemented with Xzyme™ (an exogenous enzyme-probiotic complex on the growth performance and carcass traits of albino rats. Thirty weanling albino rats with average initial liveweight of 66.9±0.3g were randomly allotted to six dietary treatments in a 3 x 2 factorial design (3 levels of rice bran [20, 40 and 60%] by 2 levels [0 and 250mg/kg of diet] of the Xzyme™. There were 5 rats on each treatment which were housed individually in plastic cages. Feed and water were provided ad libitum and their growth performance monitored for 28 days, after which the rats were slaughtered to collect carcass data.The mean values for total feed intake, weekly feed intake and daily weight gain were similar (P>0.05 for all the various dietary treatments. The addition of the Xzyme™ led to an improvement (P>0.05 in feed conversion ratio (FCR at each level of the rice bran. Both feed cost and feed cost per 100g weight gain values decreased as the level of RB increased despite the extra cost of the added Xzyme™. The carcass characteristics of the albino rats on all the six dietary treatments were similar (P>0.05. The results suggest that albino rats and probably other mono-gastric livestock species can be fed diets containing 60% rice bran plus Xzyme™ without any adverse effect on health, growth performance and carcass characteristics.

  5. Protective role of aloe vera against radiation and cadmium induced biochemical changes in the jejunum of Swiss albino mice

    International Nuclear Information System (INIS)

    Full text: The extensive use of atomic energy now a days in various branches of natural economy, science and technology, radio diagnosis, radiotherapy, industries, agriculture, nuclear research etc. has made radiation injury an urgent problem attracting the attention not only of specialists in a variety of clinical disciplines but also of a vast army of theoretical scientists. Metals like cadmium have always been intrinsic components of earth crust with the continuing trends towards and increasing human activities involving man may become exposed to concentration of toxic metals presenting a potential threat for survival. The severity of the damage can be modulated by treating the animals with antioxidants. In view of the potential for practical application, a variety of compounds are being tested for their radio protective activities. Among these, Aloe vera hold a great promise. Aloe vera juice was obtained from Millennium Agro Company, Goregaon (W) Mumbai. It is a herbal drug and known to contain well over 100 separate ingredients or constituents between those found in the leaf and mucilaginous gel inside the leaf. In light of the above, the present study was aimed to evaluate the protective effect of Aloe vera against radiation and cadmium induced biochemical changes in the jejunum Swiss albino mice. For this purpose, healthy adult male Swiss albino mice were divided into seven groups. Group I included sham-irradiated normal mice. Group II was administered CdCl2 at the dose of 20ppm, while Group III was exposed to 5.0 Gy of gamma radiation. Animals of Group IV were treated with both CdCl2 and 5.0 Gy of gamma rays. The animals of Group V and VI were treated with CdCl2 + Aloe vera and 5.0Gy + Aloe vera respectively, whereas Group VII was treated with CdCl2 +5.0Gy+ Aloe vera. In the groups V, VI and VII the Aloe vera was given seven days prior to the treatment of CdCl2 or gamma rays. Three animals from all the experimental groups were sacrificed by cervical

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

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

  8. Protective potential of Emblica Officinalis Linn. against radiation and lead induced hepatic lesion in Swiss albino mice

    International Nuclear Information System (INIS)

    Exposure of living systems to ionizing radiation causes a variety of damages to DNA and membranes due to generation of free radicals and reactive oxygen species. So there is a need of hour is to search for an ideal radioprotector which could minimize the deleterious and damaging effects caused by ionizing radiation. Radioprotectors are agents which reduce the radiation effects on cell when applied prior to exposure of radiation. The aim of this study was to access the efficacy of Emblica officinalis in reducing radiation and lead induced changes in mice liver. For the present experiment, healthy male Swiss albino mice (6-8 weeks) were selected and maintained under standard conditions of temperature and light. Fruit extract of Emblica was fed orally at the dose of 0.01 ml/animal/day.The animal were divided into seven groups according to the treatment i.e. lead acetate solution as drinking water (group-II) or exposed to 3.5 or 7.0 Gy gamma radiation (group-III) or combined treatment of radiation and lead acetate (group-IV). The animals of experimental groups were administered Emblica extract seven days prior to radiation or lead acetate treatment (group V, VI and VII) respectively. The animals from all the groups were sacrificed by cervical dislocation at each post-treatment intervals of 1, 2, 4, 7, 14 and 28 days. After sacrificing the animals pieces of liver were taken out and some of them were kept at -20℃ for different biochemical parameters. The histopathological changes included cytoplasmic degranulation, vacuolation, hyperaemia, pycnotic and crenated nuclei. The changes observed in the control groups were compared with the respective experimental groups. An increase in the value of total proteins, glycogen, acid phosphatase, alkaline phosphatase activity and RNA was observed up to day - 14 in the non drug treated group and day 7 in the Emblica treated groups, thereafter value declined up to day - 28 without reaching to normal.

  9. Chemo preventive action of Liv.52 against radiation and cadmium induced histopathological changes in the jejunum of Swiss albino mice

    International Nuclear Information System (INIS)

    The present century has been an ever-increasing use of nuclear technologies in different fields raising the alarming problem of radiation hazards to living beings including man. An increasing body of evidence indicates that human activities are responsible for global climatic changes, which, in turn, may be directly or indirectly increasing human exposure to environmental hazards. On the other hand, all forms of cadmium are poisonous leading cadmium intoxication under appropriate circumstances. The interaction between radiation and other toxicants represents a field of immense potential importance as their total environmental burden may have greater effects than expected from the sum of their individual impact. In the present study six to eight weeks old male Swiss albino mice were exposed to 2.5 and 5.0 Gy of gamma rays with or without cadmium chloride treatment. The animals of experimental groups were administered Liv.52 for seven days prior to radiation or cadmium chloride treatment. After routine procedure of histology the histopathological changes were observed in the jejunum of Swiss albino mice. The changes included loosened sub-mucosa with hydropic degeneration. Lamina propria exhibited hydropic degeneration, abnormal mitotic figures, pyknotic nuclei and cytoplasmic degranulation in crypt cells, loosened tips and shortened villi. Leucocytic infiltration appeared in lamina propria. Few mitotic figures were observed during the early intervals but were not normal and resulted in mitotic death. Recovery started on day-14 in non-drug treated groups and day-7 in Liv.52 treated groups. After irradiation with various doses of gamma rays, histological changes depend upon the dose of radiation delivered. The important radio-lesions were looseness of musculature, hydropic degeneration in sub-mucosa and lamina propria, hyperaemia and haemorrhage in sub-mucosa, pyknotic cells, cytoplasmic degranulation and vacuolation, abnormal mitotic figures.

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

    International Nuclear Information System (INIS)

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

  12. 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

    International Nuclear Information System (INIS)

    Protection of biological systems against radiation damage is of paramount importance during accidental and unavoidable exposure of radiation. Thus, development of novel and effective approaches using non toxic radioprotectors is of considerable interest for not only in the protection of normal tissue during radio therapy of tumors but also for defence (nuclear wars), nuclear industries, radiation accidents, space flights etc. Adult male Swiss albino mice were exposed to 5.0 Gy gamma radiations in the presence or absence of the Aloe vera. For this purpose 6 to 8 week old male mice were divided into seven groups; group I (sham-irradiated), group II (cadmium chloride), group III (irradiated with 5Gy. Gamma rays), group IV (radiation and cadmium chloride), group V (cadmium chloride and Aloe vera), group VI (radiation and Aloe vera), group VII (radiation, cadmium chloride and Aloe vera). Animals from all the above groups were autopsied at 1, 2, 4, 7, 14 and 28 days post treatment intervals. For histopathological studies kidney was taken out and it's pieces were fixed in Bouins fixative for 24 hours. The tissue was washed in clean water to remove excess of the fixative, dehydrated in graded series of alcohol, cleared in xylene and embedded in paraffin wax. Sections were cut at 5 μm and stained in Harris haematoxyline and alcoholic eosine. In the present experiment histopathological changes were found in the kidney of Swiss albino mice. Severe changes seen in the renal architecture after exposure of 5 Gy of gamma rays were: blurred renal architecture, intracellular oedema, damaged tubules, cytoplasmic degranulation, vacuolation and pycnotic nuclei in the cortical and medullary part. The changes were more marked on day 7, but on day 14 the signs of recovery were observed and on day 28 comparatively better renal architecture was observed. In cadmium chloride treated animals the changes observed were: cytoplasmic degranulation, vacuolation, crenated and pycnotic nuclei. The

For this purpose, four groups of male albino rats, each of five, were used as follow: control group (G 1) received no treatment, CCl4 treated group (G 2) received CCl4 at a dose of 0.2 ml/100 g body weight in sunflower oil (1/1) v/v ratio two times per week for three weeks subcutaneously, 1α hydroxyvitamin D3 treated group (G 3) received a total dose of 5 ng/g body weight of 1α hydroxyvitamin D3 dissolved in propyl alcohol divided into six doses each given twice weekly for three weeks via the subcutaneous route, and CCl4 + 1α hydroxyvitamin D3 treated group (G 4) received the same dose of CCl4 and 1α hydroxyvitamin D3 concomitantly as previously described. Liver tissues from sacrificed animals were fixed in 10% formalin before sectioning and stained with eosin and hematoxyline then were examined histopathologically. Sera from control and treated animals were separated from blood and examined for ALT, AST, alkaline phosphatase and LDH levels. Serum total protein, albumin, globulin, A/G, bilirubin, creatinine, phosphorous and Ca levels were also monitored. Data from the present study showed that administration of 1α hydroxyvitamin D3 aggravated CCl4-induced hepatotoxicity as evidenced by the exacerbation of the rise in serum ALT, AST, alkaline phosphatase levels. The analogue, however, had no effect on serum liver enzymes in CCl4 untreated rats. Though, CCl4 caused significant impairment of kidney function as shown by the rise in serum creatinine and urea levels which were differentially affected by the analogue. In conclusion, the 1α hydroxyvitamin D3 compound

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

    International Nuclear Information System (INIS)

    Nutritional Habits have changed significantly and junk foods have become widely popular, in recent years. The present study aimed to shed the light on the effect of potato chips and / or ketchup consumption on some biochemical parameters. Sixty four male and female albino rats were used in the study. Animals were maintained on 0.25 g potato chips/ rat and / or 0.125 g ketchup / rat, 5 days a week for 4 weeks. Potato chips showed the lowest body wt gain in the male rats after 4 weeks but, ketchup modulated this negative effect of the potato chips in the group of male animals fed on potato chips plus ketchup. Potato chips significantly decreased brain serotonin, liver glutathione (GSH) and catalase (CAT) in both sexes; brain dopamine, serum total proteins, albumin, total globulins, α2- and β1-globulins in the females and serum thyroxine (T4) in the male rats. Ketchup apparently affected serum T4 and A / G ratio in both sexes, brain dopamine and liver GSH in the males in addition to brain serotonin, serum total globulins and ?1-globulin in the female rats. Potato chips plus ketchup significantly changed T4, dopamine, GSH, CAT, α1 and α2-globulins in both sexes; serotonin and β1-globulin in the male rats, total proteins and albumin in the females. It could be concluded that potato chips consumption might induce numerous adverse effects in various body organs

    Full Text Available This study set out to assess the neurobehavioral effects of subchronic, oral bromocriptine methanesulfonate using the open field and the Y-maze in healthy male mice. Sixty adult Swiss albino mice were assigned into three groups. Controls received normal saline, while test groups received bromocriptine methanesulfonate at 2.5 and 5 mg/kg/day, respectively, for a period of 21 days. Neurobehavioral tests were carried out on days 1 and 21 after administration. Open field assessment on day 1 after administration revealed significant increase in grooming at 2.5 and 5 mg/kg, while horizontal and vertical locomotion showed no significant changes. Day 1 also showed no significant changes in Y-maze alternation. On day 21, horizontal locomotion, rearing, and grooming were increased significantly at 2.5 and 5 mg/kg doses after administration; also, spatial memory was significantly enhanced at 2.5 mg/kg. In conclusion, the study demonstrates the ability of oral bromocriptine to affect neurobehavior in normal mice. It also suggests that there is a cumulative effect of oral bromocriptine on the behaviors studied with more changes being seen after subchronic administration rather than after a single oral dose.

    International Nuclear Information System (INIS)

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

    Reactive oxygen species (ROS) generated from UV-B radiation have the capacity to cause oxidative decomposition which leads to the formation of toxic components as well as lipid peroxidation. Considering this fact, the present study was performed to evaluate the effect of a cream (O/W) containing the essential oil of Calendula officinalis on biochemical parameters of the skin of albino rats against UV-B radiation. The fingerprint analysis of Calendula essential oil was performed by HPLC with special reference to 1,8-cineole and α-pinene. The results indicated that the treatment with creams containing 4% and 5% of Calendula essential oil caused a significant decrease in the malonyldialdehyde level, whereas the levels of catalase, glutathione, superoxide dismutase, ascorbic acid, and the total protein level were significantly increased after 1 month of daily irradiation and treatment when compared to untreated control groups. The results suggest that the cutaneous application of the essential oil of Calendula prevents UV-B-induced alterations in the level of antioxidants in skin tissue. PMID:23008814

    G. lucidum total triterpenes were assessed for its apoptosis-inducing and anti-tumour activities. The ability of the total triterpenes to induce apoptosis was evaluated in Dalton's lymphoma ascites (DLA) and Ehrlich's ascites carcinoma (EAC) cell lines. Total triterpenes were found to be highly cytotoxic to DLA and EAC cell lines with IC50 values 5 ± 0.32 and 7.9 ± 0.2 µg/ml respectively. Total triterpenes induced apoptosis in both cell lines which is evident from the DNA fragmentation assay. Anti-tumour activity was accessed using DLA induced solid and EAC induced ascites tumour models in Swiss albino mice. Administration of 10, 50 and 100 mg/kg b. wt. total triterpenes showed 11.86, 27.27 and 40.57% increase in life span of animals in ascites tumour model. Treatment with 10, 50 and 100 mg/kg b. wt. total triterpenes exhibited 76.86, 85.01 and 91.03% inhibition in tumour volume and 67.96, 72.38 and 77.90% inhibition in tumour weight respectively in the solid tumour model. The study reveals the significant dose-dependent anti-tumour activity of total triterpenes in both models. Total triterpenes were more active against the solid tumour than the ascites tumour. The anti-oxidant potential and ability to induce cell-specific apoptosis could be contributing to its anti-tumour activities. PMID:27188870

    Reactive oxygen species are believed to be involved in the development of sepsis. Plant-derived phenolic compounds are thought to be possible therapeutic agents against sepsis because of their antioxidant properties. Rosmarinic acid (RA) is a phenolic compound commonly found in various plants, which has many biological activities including antioxidant activity. The aim of this study was to investigate the effects of RA on sepsis-induced DNA damage in the lymphocytes and liver and kidney cells of Wistar albino rats by alkaline comet assay with and without formamidopyrimidine DNA glycosylase protein. The oxidative stress parameters such as superoxide dismutase (SOD) and glutathione peroxidase (GSH-Px) activities and total glutathione (GSH) and malondialdehyde (MDA) levels in the liver and kidney tissues and an inflammatory cytokine, tumor necrosis factor α (TNF-α) level in plasma were also evaluated. It is found that DNA damage in the lymphocytes, livers, and kidneys of the RA-treated rats was significantly lower than that in the sepsis-induced rats. RA treatment also decreased the MDA levels and increased the GSH levels and SOD and GSH-Px activities in the livers and kidneys of the sepsis-induced rats. Plasma TNF-α level was found to be decreased in the RA-treated rats. It seems that RA might have a role in the attenuation of sepsis-induced oxidative damage not only by decreasing the DNA damage but also by increasing the antioxidant status and DNA repair capacity of the animals.

  3. Embryonic/fetal mortality after exposure to tritiated water in pregnant Swiss albino mice during different gestation periods

    International Nuclear Information System (INIS)

    Pregnant Swiss albino mice were given a priming injection(im) of tritiated water (HTO) at the dose rate of 2.3 and 5 μCi/ml body water (74, III or 185 K Bq/ml body water) at 0,6 and 14 day post conception (d.p.c) and were subsequently maintained on tritiated drinking water ad libitum during preimplantation (0-5 d.p.c), organogenetic (6-12 d.c.p.) or fetal (14-18 d.p.c) period, respectively. On day 18 of gestation the females were sacrificed by cervical dislocation to record the implant sites per dam and embryonic/fetal mortality. Significant reduction was observed in average implant sites per dam when the females were exposed to any of the three doses during the preimplantation period due to embryonic resorption before implantation. However, the same was found to be within the normal range when mothers were exposed during the organogenetic or fetal period. Prenatal mortality (embryonic resorption/fetal death) was higher after in utero exposure to different doses during preimplantation period as compared to organogenetic period, but mortality did not occur after exposure to any of the doses during the fetal period. Occurrence of mortality was found to be dose dependent. (author). 25 refs., 1 tab

    Full Text Available Population explosion is a major problem it is raising tremendously; this may affect drastically the economic growth. So family planning has been promoted through several methods of contraception. A wide variety of synthetic contraceptive agents are available, but these cannot be used continuously due to their side effects. Thus the present study was to evaluate the effect of Bougainvillea spectabilis on fertility of male and female mice. Swiss Albino mice were orally administered with aqueous crude extract of the leaves of Bougainvillea spectabilis (800 mg/kg of body weight/day, for 30 days, and effect of crude extract on reproductive organs and fertility was investigated. The treatment Caused decrease in weight of testis, sperm count and the histological examination revealed a reduction in the size of seminiferous tubules along with the thickness of germinal epithelial cells, though some of the epithelial cells and interstitial cells of leydig showed hypertrophy. Moreover, the lumen of the tubules was found to be devoid of sperms. On the other hand, in treated females no histological changes could be observed. The only marked change, which could be visualized, was the slight disruption of estrous cycle having prolonged metaestrus phase, which has been increased by 145.28 %. The overall duration of estrous cycle had been extended by more than one day. The hormonal profile was also influenced by the Bougainvillea spectabilis extract. The testosterone and estrogen levels were significantly decreased.

    Objective:To investigate the effects of the flavonoid rich fraction of Monodora tenuifolia seed on the haematology, histopathology and liver profile of Wistar albino rats. Methods:Toxicity study was investigated on the flavonoid rich fraction of Monodora tenuifolia in rats administered different concentrations orally for 28 d using standard laboratory procedures. Results:The LD50 of the flavonoid rich fraction was found to be above 5 000 mg/kg body weight in mice observed for 48 h. After the Day 14, biochemical markers of liver injury such as serum alanine aminotransferase, and aspartate aminotransferase decreased significantly (P0.05). There was non-significant (P>0.05) effect observed across the groups in the levels of serum total protein, albumin, globulin, urea and creatinine. The result of histological examination showed various degrees of peribiliary hepatitis after the Day 14 which fizzled out after the Day 28. Conclusions:The result therefore suggests that the seed extract is potentially safe.

  6. Influence of Alpha Tocopherol on Heat Stress-Induced Changes in the Reproductive Function of Swiss Albino Mice

    International Nuclear Information System (INIS)

    The present study was carried out to investigate the influence of vitamin E (alpha-tocopherol) on heat stress-induced changes in the reproduction of Swiss albino mice. The evaluated parameters include: the estrous cycle, fertility, post-implantation losses of fetuses and estimation of progesterone levels in the serum. Eight groups of experimental mice (10 each) were used. Groups 1-4 (24 degree C) consisted of a control and alpha-tocopherol (100, 200 and 400 mg/kg) treated groups. Groups 5-8 (42 degree C) consisted of a positive control and alpha-tocopherol (100, 200 and 400 mg/kg) treated group. Heat-stress reduced significantly (p > 0.001) the number of fetuses and corpora lutea. There was also a significant decrease in the mean weights of fetuses (p > 0.001) and placenta (p > 0.01) in the heat-stress group with a decrease in their serum progesterone levels (p > 0.01). Heat-stress groups treated with high doses of alpha-tocopherol 200 and 400 mg/kg, showed protection against heat-stress related abnormalities. The results showed that alpha-tocopherol plays a role in protection against hyperthermia induced changes in the estrous cycle length, infertility, post-implantation losses and depletion in the serum level of progesterone.

    2013-03-01

    Full Text Available There are reports about a possible weak local anaesthetic activity of nicorandil, a potassium channel agonist (PCA. In addition, modification of local anesthetic activity of lignocaine by PCA is not clearly defined. The objective of the present study is to evaluate local anesthetic activity of nicorandil and to evaluate the influence of nicorandil on the efficacy and duration of local anesthesia by lignocaine. A total number of 84 albino rats of either sex were divided into 14 groups of 6 animals each. Two methods, sciatic nerve blockade and tail clip method were applied for the study. Control group received 0.2ml normal saline, whereas the study group received 0.2ml of 1% drug solution (lignocaine or nicorandil combined with 0.9% sodium chloride. The results showed weak local anaesthetic activity with the higher dosages of nicorandil (10 mg/kg, 100mg/kg. Combination of nicorandil (1mg/kg, 10mg/kg and 100mg/kg and lignocaine (5mg/kg yielded synergistic results like decreased onset latency and prolonged reaction time. To conclude unquestionably there are multiple mechanisms involved for causation of local anesthetic effect by drugs like lignocaine. PCAs like nicorandil will influence the activity of these drugs as observed in the present study. Mechanism of this may be complex. Nicorandil may increase the plasma membrane permeability to potassium causing hyper polarization and moves the membrane potential away from the threshold required to generate an action potential.

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

    International Nuclear Information System (INIS)

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

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

    International Nuclear Information System (INIS)

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

    Ghrita (ghee) is the foremost substance of Indian cuisine from centuries. Ayurvedic classics described eight kinds of ghee from eight different animal milk, among them ghee made from cow milk is said to be the superior and ghee of ewe milk is said to be the inferior and also detrimental to heart. The present study was undertaken to evaluate chronic administration of cow ghee (Go Ghrita) and ghee of ewe milk (Avika Ghrita) to experimental animals. Experiment was carried out on Wistar strain albino rats and study was done at two dose levels. The test drugs were administered orally for 45 consecutive days. Parameters, such as gross behavior, body weight, weight of important organs, total fecal fat content, electrocardiogram, serum biochemical parameters, and histopathology of different organs were studied. Both the test drugs did not alter the gross behavior, body weight, weight of organs, and cytoarchitecture of different organs to significant extent. Avika Ghrita at a low dose significantly decreased triglyceride content, significantly prolonged QTc and at both dose levels it significantly shortened the PR interval. This study shows chronic administration of Avika Ghrita and Go Ghrita has no marked differences between them except the QTc prolongation in Avika Ghrita. This may be the basis for the classics to categorize Avika Ghrita as Ahridya. PMID:23723655

    4-Methylimidazole (4-MEI) is formed during the production of certain caramel coloring agents used in many food and drink products. It may also be formed during the cooking, roasting, or other processing of some foods and beverages. So it was unintentionally consumed in worldwide. This study was aimed to investigate the genotoxic and cytotoxic effects of 4-MEI using chromosome aberration (CA) and mitotic index (MI) in Swiss Albino mice. In this research, CA and MI of the mouse bone marrow cells were analyzed after treating the animals with 4-MEI (100, 130 and 160 mg/kg) for 12 h and 24 h treatment times. All data were analyzed using statistical methods. 4-MEI significantly increased the percentage of CAs at all concentrations for 12 h and at highest concentration for 24 h treatment periods. 4-MEI at highest concentration for 12 h and at all concentrations for 24 h decreased the MI in comparison with control. Genotoxic and cytotoxic effects of 4-MEI at 24 h treatment periods were concentration dependent. Consequently, it can be said that 4-MEI have genotoxic and cytotoxic effect in mouse. PMID:26634952

Immobilization stress induced due to reduced floor area provided for the mobility results in the imbalance of oxidant and antioxidant status. The modern computer savvy world decreases human mobility in the working environment, leading to the formation of oxygen free radicals and if left untreated might result in severe health problems like hypertension, cardiovascular disease, premature aging and brain dysfunction. Hence, modern medicines rely upon the medicinal plants for some drugs with zero side effects. In this context, Jyothismati oil (JO, extracted from Celastrus paniculatus seeds, was used to treat acute and chronic immobilization induced experimentally. C. paniculatus plant is considered to be rich in antioxidant content and so the seed oil extract′s efficacy was tested against immobilization stress in albino mice. The animals were kept in a restrainer for short and long durations, grouped separately and fed with the drug. Animals were sacrificed and the samples were analyzed. The antioxidant enzyme levels of the animals regained and markedly increased in the acute and chronic immobilized groups, respectively. The results suggested that the extract of C. paniculatus seed was highly efficacious in reducing the stress induced by least mobility for hours.

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

Restraint stress-induced (a increased latency and (b decreased ambulation and rearing were also reversed by O. sanctum and C. sinensis in OFT. A significant increase in immobility period was observed in FST and TST after restraint stress. O. sanctum and C. sinensis significantly reduced the immobility times of rats in FST and TST. Conclusion : O. sanctum and C. sinensis possess anxiolytic and antidepressant activities.

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

    International Nuclear Information System (INIS)

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

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

  1. Protective efficacy of Emblica officinalis Linn. against radiation and cadmium induced biochemical alterations in the liver of Swiss albino mice

    International Nuclear Information System (INIS)

    All organisms living on earth are being perpetually exposed to some amount of radiation originating from a variety of sources. Radiation causes deleterious effects in all forms of life due to increasing utilization and production of modern technology, a simultaneous exposure of organisms to heavy metals is also unavoidable. These heavy metals become toxic when present in large quantities, with increasing the industrial revolution and industrial waste, the emission of cadmium has increased into the environment. Thus concomitant exposure to cadmium chloride and ionizing radiation might produce deleterious effect upon biological system. The total environmental burden of toxicants may have greater effect as against their individual impact as expected by their nature. So interaction between radiation and other toxicants represents a field of great potential importance. In the recent years, immense interest has been developed in the field of chemoprotection against radiation and heavy metals induced changes. In view of the potential for practical application, a variety of compounds are being tested for their radioprotective activities. Among these, Emblica holds a great promise. In light of the above, the present study was aimed to evaluate the protective effect of Emblica against radiation and cadmium induced biochemical alterations in the liver of Swiss albino mice. The animals were exposed to 6.0 Gy of gamma rays with or without cadmium chloride treatment. The Emblica was administered seven days prior to irradiation or cadmium chloride treatment

    International Nuclear Information System (INIS)

    In the present investigation, the protective efficacy of Liv.52 against radiation and cadmium induced haematological changes in Swiss albino mice has been studied. For the purpose, the animals were exposed to 3.0 and 6.0 Gy gamma rays with or without cadmium chloride treatment. The Liv.52 was administered at the dose of 0.01 ml/animal/day seven days prior to radiation, cadmium or combined treatment. The various haematological changes viz. RBC, WBC, Hb, PCV, MCR, MCHC, TLC, SGPT and SGOT were observed in the form of increase or decrease. The values of RBC, WBC, Hb, PCV and MCV were found to decrease in all the groups as compared to normal group. The values of MCR and MCHC increased in all the groups as compared to normal group after 1, 2, 4, 7, 14 and 28 days of post-treatment intervals. The values of SGOT and SGPT elevated up to day-14 in the non drug treated groups and day 7 in the Liv.52 treated groups, thereafter a fall in the value was seen up to day-28. After combined treatment of radiation and cadmium the changes were more severe and there was late manifestation of recovery showing synergistic or additive effect. In the Liv.52 treated animals the changes were less severe and early recovery was also observed showing protection provided by the drug. (author)

  4. Radioprotective effect of Tamarindus indica pod extract in Swiss albino mice exposed to whole body electron beam radiation

    International Nuclear Information System (INIS)

    The objective of the study was to investigate the radioprotective effect of Tamarindus indica pod extract against radiation induced damage.The effect of 100 mg of hydroalcoholic extract of Tamarindus indica pod was studied in Swiss albino mice exposed to 6 Gy whole body electron beam radiation. Treatment of mice with extract for 15 days before irradiation reduced the symptoms of radiation sickness when compared with the untreated irradiated group. The irradiated animals showed an elevation in lipid peroxidation and reduction in glutathione, total antioxidants and antioxidant enzymes such as glutathione peroxidase and catalase activities. Radiation induced mice has shown micronucleus in the bone marrow cells. Treatment of mice with Tamarindus indica pod extract before irradiation caused a significant reduction in lipid peroxidation followed by significant elevation in reduced glutathione, total antioxidants, glutathione peroxidase and catalase activity. It also showed a reduction in the micronucleus formation in bone marrow cells. Results indicate that the radioprotective activity of Tamarindus indica pod extract may be due to free radical scavenging attributed as a result of increased antioxidant level in mice. (author)

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

    International Nuclear Information System (INIS)

    The effect of chronic and acute doses of aspirin and prostaglandins F2α and E2 individually on the oxidation of glucose through Embden Meyerhof-TCA cycle and pentose phosphate pathways and some key glycolytic enzymes of liver were studied in male albino rats. Studies were extended to find the combined effect of PGF2α and E2 with an acute dose of aspirin. There was increased utilisation of both 1-14C glucose and 6-14C glucose on aspirin treatment. However, the metabolism through the EM-TCA pathway was more pronounced as shown by a reduced ratio of 14CO2 from 1-14C and 6-14C glucose. Two hepatic key glycolytic enzymes viz. hexokinase and pyruvate kinase were increased due to aspirin treatment. Withdrawal of aspirin corrected the above impaired carbohydrate metabolism in liver. Prostaglandin F2α also caused a reduction in the utilisation of 1-14C glucose, while PGE2 recorded an increase in the utilisation of both 1-14C and 6-14C glucose when compared to controls, indicating that different members of prostaglandins could affect metabolisms and differently. Administration of the PGs and aspirin together showed an increase in the utilisation of 6-14C glucose. (auth.)

    The aim of this study was to obtain the normative data on the age-dependent transformation of morphometric and histochemical characteristics of neurocytes in different ganglia in albino rats. Cell cross-sectional area, activities of cholinesterase (demonstrated with thioacetic acid method) monoamine oxidase (demonstrated with Glenner method) were measured in neurocytes of stellate, spinal, trigeminal and gastric ganglia in rats aged 2 to 360 days. Measurements were made with the help of "Bioscan" videoanalyzer. Informational analysis was used for the evaluation of the degree of maturation of neurocyte systems. General features, age- and organ-related peculiarities of morphometric and enzyme-histochemical characteristics were established for neurocytes of different ganglia, as well as a heterochronism of their definitive state attainment. The time of stabilization for neurocytes of stellate and I thoracic spinal ganglia was the age of 60 days, for those of trigeminal ganglion and intramural gastric ganglia -90 and 120 days, respectively. By this time, neurocyte systems turned from a determined state into a probabilistic-determined one, this transformation being considered as a population stabilization. PMID:15359692

    Embryonic stem (ES) cells from a C57BL/6N (B6N) background injected into B6(Cg)-Tyrc-2J/J (B6-albino) recipient blastocysts are commonly used for generating genetically modified mouse models. To understand the influence of the recipient blastocyst strain on germline transmission, BALB/cAnNTac and B6-albino germline transmission rates were compared using the C57BL6/N-derived C2 ES cell line. A total of 92 ES cell clones from 27 constructs were injected. We compared blastocyst yield, birth rate, chimera formation rate, and high-percentage (>50 %) male chimera formation rate. For germline transmission, we analyzed 24 clones from 19 constructs, which generated high-percentage male chimeras from both donor strains. B6-albino hosts resulted in higher mean blastocyst yields per donor than did BALB/c ones (3.6 vs. 2.5). However, BALB/c hosts resulted in a higher birth rate than B6-albino ones (36 vs. 27 %), a higher chimera formation rate (50 vs. 42 %), a higher high-percentage male chimera rate (10 vs. 8 %), and a higher germline transmission rate (65 vs. 49 %), respectively. Our data suggest that BALB/c is a suitable blastocyst host strain for C2 ES cells and has an advantage over the B6-albino strain for receiving the injection of C2 ES cells. PMID:26852382

    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-α and IL-6 was observed in group intoxicated with sod-borate(GII) when compared to control rats(GI). Oral supplementation with high potent antioxidant GSE (GIII) caused alleviation in the kidney injury leading to the reduction of both pro-inflammatory mediator cytokines TNF-α and IL-6. DNA% fragment migration showed that worse significant migration of DNA fragements were observed in toxicated group(GII) followed by increase in

    Objective: To evaluate the other pharmacological actions of silymarin in Albino rats and mice such as antipyretic, anti-inflammatory, antinociceptive and antihyperlipidemic effects. Methods: Rats were injected intramuscularly with pyrogenic dose of brewer’s yeast for the antipyretic test of silymarin. Another group of rats injected with 0.1 mL of 1% carrageenan solution in saline at the subplanter area of the right hind paw for the anti-inflammatory test of silymarin. Another group of mice tested by hot plate method for determination of antinociceptive effect of silymarin. Hyperlipidemia was induced using high fat diet for 2 months to estimate the antihyperlipidemic activity of silymarin. Results: Silymarin showed a significant antipyretic effect of both doses(50 and 100 mg/kg) compared with control untreated group. Moreover, silymarin elucidated a significant anti-inflammatory effect of both doses reflected on the decrease of the rat paw edema every hour interval for 4 h after administration in comparison with control positive group. By the same taken, both doses of silymarine revealed a significant antinociceptive action in hot plate method at 30 and 60 min post administration. Besides, it lowered significantly the serum levels of prostaglandin E2, tumor necrosis factor alpha and interleukin 1 beta after 2 h of silymarin administration in carrageenan induced rat paw edema besides the significant decrease of total cholesterol, triglycerides, low density lipoprotein and significantly elevated high density lipoprotein after 2 weeks of silymarin administration. Conclusions: These outcomes delivered a new vision into the possible pharmacological mechanisms by which silymarin advances antipyretic, anti-inflammatory, antinociceptive and antihyperlipidemic effects.

    Full Text Available Background: There is a lack of reliable hepatoprotective drugs in modern medicine to prevent and treat drug-induced liver damage. Leaves of Sacred/Holy Basil, i.e. Green Tulsi (Ocimum sanctum, belonging to family Lamiaceae are used traditionally for their hepatoprotective effect. We wanted to evaluate the hepatoprotective activity of Ocimum sanctum and observe whether synergistic hepatoprotection exists with silymarin. Materials and Methods: Albino rats (150-200 g were divided into five groups. Groups A and B were normal and experimental controls, respectively. Groups C, D and E received the alcoholic extract of Ocimum Sanctum leaves (OSE 200 mg/kg BW/day, silymarin 100 mg/kg BW/day and OSE 100 mg/kg BW/day + silymarin 50 mg/kg BW/day p.o., respectively, for 10 days. Hepatotoxicity was induced in Groups B, C, D and E on the eighth day with paracetamol 2 g/kg BW/day. The hepatoprotective effect was evaluated by performing an assay of the serum proteins, albumin globulin ratio, alkaline phosphatase, transaminases and liver histopathology. The assay results were presented as mean and standard error of mean (SEM for each group. The study group was compared with the control group by one-way ANOVA, followed by Bonferoni′s test. A P-value of <0.01 was considered significant. Results: In groups C, D and E, liver enzymes and albumin globulin ratio were significantly (P < 0.01 closer to normal than in group B. Reduction in sinusoidal congestion, cloudy swelling and fatty changes and regenerative areas of the liver were observed on histopathological examination in groups C, D and E, whereas group B showed only hepatic necrosis. Conclusion: The Ocimum sanctum alcoholic leaf extract shows significant hepatoprotective activity and synergism with silymarin.

    Photodynamic damage to normal tissues, including skin, appears to occur by photooxidative damage to the normal microvasculature as the primary target sensitized by HPD bound to the vascular wall or endothelial cell. Initial damage to the microvasculature was measured by the increase in vascular permeability (VP) as measured by Evans Blue dye (EB) extravasation as a function of HPD and laser light (632 nm) dose. Albino, Swiss-Webster mice (female 122-25 g, 5 mice per group) were injected intraperitoneally (IP) with incremental doses of HPD (1, 10, 20, 30, 40 and 50 mg/kg). After 48 hours the left ear of each mouse was masked as a control and the right ear was irradiated at 632 nm using the Aurora-Lexel Argon-dye laser with an intensity of 50 mW/cm2 and light doses of 0, 25, 50, 75, and 100 J/cm2 directed to a 3-mm spot on the mouse ear. No EB leakage occurred in the absence of HPD at any light dose or in the absence of light at any HPC dose. Vascular permeability increased as a function of HPD dose up to 30 mg/kg. AT 50 mg/kg HPD, there was a decrease in VP. At each HPD dose above 10 mg/kg, the VP increased as a function of light dose up to 75 J/cm2. Further increase in light dose was without effect. The amount of HPD porphyrin recovered from irradiated ears decreased as a function of light dose. There appeared to be an irreversible photo destruction of the porphyrin exposed to light.

  14. Protective effects of Punica Granatum (L) and synthetic ellagic acid on radiation induced biochemical alterations in Swiss albino mice

    International Nuclear Information System (INIS)

    Ionizing radiations produce deleterious effects in the living organisms and the rapid technological advancement has increased human exposure to ionizing radiations enormously. Radiotherapy, which is a chief modality to treat cancer, faces a major drawback because it produces severe side effects developed due to damage to normal tissue by reactive oxygen species (ROS). Recent studies have indicated that some commonly used medicinal plants may be good sources of potent but non-toxic radioprotectors. The pomegranate, Punica granatum L., an ancient, mystical, and highly distinctive fruit, is the predominant member of the Punicaceae family. It is used in several systems of medicine for a variety of ailments. The objective of the present study was to investigate the protective effects of ethanolic extracts of pomegranate whole fruit (EPWF) and seeds (EPS) and Synthetic Ellagic acid (EA) against Electron beam radiation(EBR) induced biochemical alterations in Swiss albino mice. The extracts and synthetic compound were assessed for its radical scavenging property by DPPH radical scavenging and Ferric Reducing Antioxidant Power assays. The animals were exposed to sub-lethal dose (6 Gy) of Electron Beam Radiation and then treated with 200 mg/kg body wt. of pomegranate extracts and synthetic ellagic acid for 15 consecutive days. The biochemical estimations were carried out in the liver homogenate of the sacrificed animals. Radiation induced depletion in the level of reduced glutathione and total antioxidant capacity were prevented significantly by EPWF, EPS and EA administration. Also there was significant reduction in the levels of membrane lipid peroxidation in the treated groups compared to irradiated control. The findings of our study indicate the protective efficacy of pomegranate extracts and synthetic ellagic acid on radiation induced biochemical changes in mice may be due to its free radical scavenging and increased antioxidant levels.

  15. Biochemical histological and histochemical changes induced in pregnant albino rats as affected by SILYMARIN treatment and/or gamma irradiation

    International Nuclear Information System (INIS)

    Silymarin is a mixture of flavonoids extracted from seeds of milk thistle (Silybum marianum), that has been used in the treatment of liver diseases. Flavonoids are a large group of polycyclic phenols of plant origin that are displaying estrogenic effects. Silybum marianum has been traditionally used in Egypt for its antifertility effect. The objective of this study was to evaluate the side effects of silymarin administration and / or exposure to gamma radiation in pregnant rats. Silymarin at a dose level 75.6 mg/kg body weight was daily administered via an oral stomach tube to pregnant adult albino rats from the 1st to the 20th day of pregnancy while mothers were subjected to gamma radiation (1.5 Gy) as fractionated dose; 0.75 Gy on the 6th day and 0.75 Gy on 12th day of pregnancy. Experimental investigations carried out one day prior to parturition have demonstrated that silymarin intake throughout the whole gestational period induced biochemical, histopathological and histochemical disorders in irradiated mothers. The data obtained revealed that silymarin administration and/or gamma radiation exposure caused significant elevation in levels of follicle stimulating hormone (FSH), the luteinizing hormone (LH) and estradiol in pregnant rats.Moreover, the histopathological results showed different distortions which varied from hyperemic blood vessels, fibroblasts in the ovary, degenerated uterine glands, erosion in the lining epithelia of the uterus and degenerated epithelial cells, necrosis in trophospongium, necrosis in the giant cells, massive blood in the labyrinth and cytoplasmic vacuolation in the placenta. In addition, the histochemical observations revealed various diminutions in each of the polysaccharides, total protein and DNA content. Conclusively, these findings proved that radiation exposure and/or silymarin intake could exert deleterious effect, therefore, it is recommended that radiation occupational workers especially females have to be careful toward

    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)

    Introduction Numerous herbal medicines have been recommended for the treatment of different diseases. Achyranthes aspera, Linn. (Family: Amaranthaceae), popularly known as Charchitta or Pitpapra, is commonly used by traditional healers for the treatment of fever, malaria, dysentery, asthma, arterial hypertension, pneumonia, and diabetes. The root extract is well reputed for its insect molting hormonal activity. This investigation was conducted to evaluate the effects of saponins from Achyranthes aspera seeds on the serum lipid profile of albino rats fed a high cholesterol diet. Material and methods Hypolipidemic, antioxidant and hepatoprotective activities of these saponins were tested as described previously. To determine the mechanism underlying the observed effects, serum antioxidant status was assessed according to ABTS (2,2’-azino-bis-3-ethylbenzo-thiazoline-6-sulfonic acid), superoxide dismutase and ferric ion reducing antioxidant power (FRAP) assays in saponin-treated hyperlipidemic animals. Liver enzyme levels were determined to reveal any possible hepatotoxicity. Results Four-week oral administration of A. aspera seed saponins produced a significant (p < 0.05) decrease of total cholesterol, total triglycerides and LDL-C and a significant increase of HDL-C level in hyperlipidemic rats. Treatment with A. aspera seed saponins also showed a significant (p < 0.01) improvement of serum antioxidant status in tested animals. No significant hepatotoxicity was produced by such treatment as the serum liver enzyme activity remained unaltered. Conclusions Saponins from A. aspera seeds possess antihyperlipidemic and antioxidant properties which might lead to improvement of serum lipid profile and blood antioxidant status. Our findings support the folkloric use of this indigenous plant in the treatment of hyperlipidemia. However, its exact mechanism of action remains to be elucidated. PMID:26788089

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

    Objective: To evaluate the hepatoprotective and immunotherapeutic effects of aqueous extract of turmeric rhizome in CCl4 intoxicated Swiss albino mice. Methods: First group of mice (n=5) received CCl4 treatment at a dose of 0.5 mL/kg bw (i.p.) for 7 days. Second group was fed orally the aqueous extract of turmeric at a dose of 50 mg/kg bw for 15 days. The third group was given both the turmeric extract (for 15 days, orally) and CCl4 (for last 7 days, i.p.). The fourth group was kept as a control. To study the liver function, the transaminase enzymes (SGOT and SGPT) and bilirubin level were measured in the serum of respective groups. For assaying the immunotherapeutic action of Curcuma longa (C. longa), non specific host response parameters like morphological alteration, phagocytosis, nitric oxide release, myeloperoxidase release and intracellular killing capacity of peritoneal macrophages were studied from the respective groups. Results: The result of present study suggested that CCl4 administration increased the level of SGOT and SGPT and bilirubin level in serum. However, the aqueous extract of turmeric reduced the level of SGOT, SGPT and bilirubin in CCl4 intoxicated mice. Apart from damaging the liver system, CCl4 also reduced non specific host response parameters like morphological alteration, phagocytosis, nitric oxide release, myeloperoxidase release and intracellular killing capacity of peritoneal macrophages. Administration of aqueous extract of C. longa offered significant protection from these damaging actions of CCl4 on the non specific host response in the peritoneal macrophages of CCl4 intoxicated mice. Conclusions: In conclusion, the present study suggests that C. longa has immunotherapeutic properties along with its ability to ameliorate hepatotoxicity.

    OBJECTIVE:The purpose of the present study was to evaluate the nephroprotective and antioxidant properties of Triphala against bromobenzene-induced nephrotoxicity in female Wistar albino rats. METHODS:Animals were divided into ifve groups of six rats and treated as fol ows:Group I was a normal control and received no treatment, Group II received only bromobenzene (10 mmol/kg), Groups III and IV received bromobenzene and Triphala (250 and 500 mg/kg, respectively), Group V received Triphala alone (500 mg/kg), and Group VI received bromobenzene and silymarin (100 mg/kg). Antioxidant status and serum kidney functional markers were analyzed. RESULTS:Bromobenzene treatment resulted in signiifcant (P<0.05) decreases in the activities of antioxidant enzymes such as catalase, superoxide dismutase, glutathione-S-transferase and glutathione peroxidase as wel as total reduced glutathione. There was a signiifcant (P<0.05) increase in lipid peroxidation in kidney tissue homogenates. There were signiifcant (P<0.05) reductions in the levels of serum total protein and albumin as wel as signiifcant (P<0.05) increases in serum creatinine, urea and uric acid. The oral administration of two different doses (250 and 500 mg/kg) of Triphala in bromobenzene-treated rats normalized the tested parameters. The histopathological examinations of kidney sections of the experimental rats support the biochemical observations. CONCLUSION:Triphala treatment al eviated the nephrotoxic effects of bromobenzene by increasing the activities of antioxidant enzymes and reducing the levels of lipid peroxidation and kidney functional markers.

    The objective of this study was to investigate the modulatory role of Prunus avium fruit extract (PAE) on several blood parameters after exposure to 10-GHz microwaves. Swiss albino mice from an inbred colony were selected and divided into 3 groups. Mice in group I served as the control; they were placed in a Plexiglas cage (without energizing the system) for 2 hours/day for 30 consecutive days. Group II mice were exposed to 10-GHz microwaves for 2 hours/day for 30 consecutive days. Mice in group III received PAE (500 mg/kg/body weight) orally once daily 1 hour before exposure to 10-GHz microwaves (2 hours/day) for 30 consecutive days. After 30 days of treatment, blood samples were collected from mice in all groups and analyzed. Hemoglobin, monocytes, packed cell volume, red blood cells, mean corpuscular hemoglobin concentration declined significantly (P ≤ 0.01), whereas white blood cells, lymphocytes, erythrocyte sedimentation rate, and mean corpuscular volume increased significantly (P ≤ 0.01) compared to the control group (group I). Cholesterol, alkaline phosphatase, and lipid peroxidation also increased significantly (P ≤ 0.01). Depletion in blood sugar, total protein, acid phosphatase, and glutathione levels was noted after microwave exposure compared with levels in the sham-exposed (control) mice. Histopathological alterations in blood cells also were seen. Signs of improvements in the hematological, biochemical, and histopathological parameters were recorded in group III, where PAE was supplemented before exposure. Exposure to microwaves influences hematological parameters, which could be ameliorated by the supplementation of PAE. PMID:24266407

  4. Chloroquine causes similar electroretinogram modifications, neuronal phospholipidosis and marked impairment of synaptic vesicle transport in Albino and Pigmented Rats

    International Nuclear Information System (INIS)

    Retinal toxicity of chloroquine has been known for several years, but the mechanism(s) of toxicity remain controversial; some author support the idea that the binding of chloroquine to melanin pigments in the retinal pigmented epithelium (RPE) play a major toxic role by concentrating the drug in the eye. In our study, 12 albinos Sprague-Dawley (SD) and 12 pigmented Brown Norway (BN) rats were treated orally for 3 months with chloroquine to compare functional and pathological findings. On Flash electroretinograms (ERG) performed in scotopic conditions, similar and progressive (time-dependent) delayed onset and decreased amplitudes of oscillatory potentials (from Day 71) and b-waves (on Day 92) were identified in both BN and SD rats. In both strains, identical morphological changes consisted of neuronal phospholipidosis associated with UV auto-fluorescence without evidence of retinal degeneration and gliosis; the RPE did not show any morphological lesions or autofluorescence. IHC analyses demonstrated a decrease in GABA expression in the inner nuclear layer. In addition, a marked accumulation of synaptic vesicles coupled with a marked disruption of neurofilaments in the optic nerve fibers was identified. In conclusion, ERG observations were very similar to those described in humans. Comparable ERG modifications, histopathology and immunohistochemistry findings were observed in the retina of both rat strains suggesting that melanin pigment is unlikely involved. chloroquine-induced impairment of synaptic vesicle transport, likely related to disruption of neurofilaments was identified and non-previously reported. This new mechanism of toxicity may also be responsible for the burry vision described in humans chronically treated with chloroquine

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

    International Nuclear Information System (INIS)

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

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

  7. Protective efficacy of Emblica against radiation and lead induced changes in the Jejunum of Swiss Albino mice

    International Nuclear Information System (INIS)

    Recently, increased interest has developed on search for potential drugs of plant origin which can quench the radiation induced free radicals and eliminate oxygen with minimum side effects. In view of the fact, present study was planned to evaluate the protective efficacy of Emblica against radiation and lead induced changes in jejunum of mice. For the purpose, six to eight weeks old male Swiss albino mice were selected and divided into seven groups on the basis of radiation, lead, combined treatment and drug treated. The values of total proteins, cholesterol, acid phosphatase activity, alkaline phosphatase activity, DNA and RNA were estimated. The values of total proteins, cholesterol, DNA and RNA decreased whereas acid phosphatase and alkaline phosphatase activity increased. After irradiation with various doses of gamma rays, histological changes depend upon the dose of radiation delivered. The important radio-lesions were looseness of musculatrue, hydropic degeneration in submucosa and lamina propria, hyperaemia and haemorrhage in submucosa, pyknotic cells, cytoplasmic degranulation and vacuolation, abnormal mitotic figures. Karyolysis, karyorrhexis and chromatolysis were also observed in crypt cells. Shortening and breaking of villus tips, leucocytic infiltration in lamina propria and cell debris in intestinal lumen were also noted. The number of goblet cells per crypt section also decreased in all the experimental groups. The value of the experimental groups was significantly lower than that of the control group. The biochemical finding indicated the drug treated section of living tissue showed slightly/no degenerative changes. The drug treated groups demonstrating the ability of Aloe vera to inhibit oxidative stress thus preventing tissue injury. (author)

    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

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

    International Nuclear Information System (INIS)

    The present study was designed to investigate 1,3,5-[U-14C]trioxane (TOX) distribution, excretion and metabolism. The experiments were performed on male Wistar albino rats after a single administration of TOX at doses of 40 mg/kg and 400 mg/kg. The exhaled air proved to be the main route of 14C elimination, mainly as 14CO2. During the first 12 h following the administration of 40 mg/kg of TOX the exhalation of 14CO2 was monophasic, with a half-life of 3.5 h. After the administration of 400 mg/kg, TOX was eliminated mainly as 14CO2 with the exhaled air (77%) and unchanged TOX (8%). About 3% of 14C was excreted in the urine as unchanged 1,3,5-trioxane. With regards to TOX elimination from blood plasma for the lower dose, a biphasic process was observed, with half-lives of 4.5 and 72 h. The amount of 14C bound by the erythrocytes was minute compared with the amount in blood plasma. When the higher dose of TOX was administered the efficiency of 14C binding to the erythrocytes was found to be 10 times higher than the respective value for blood plasma. Among the examined tissues the highest concentration of TOX-derived radioactivity was detected in the liver while the lowest was in fat tissue and brain. A subsequent decay of radioactivity occurred in the tissues. The results of the present study indicate that TOX belongs to the group of compounds, which 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.

  10. 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

    Full Text Available The present study was designed to evaluate the cardioprotective potential of Citrus grandis (L. Osbeck (CGO peel extract in rats. Citrus grandis (L. Osbeck peel extract was evaluated for protection against cyclophosphamide (200 mg/kg body wt., i.p. and doxorubicin (15 mg/kg body wt., i.p. induced cardiotoxicity in male albino rats. Biomarkers like lactate dehydrogenase (LDH, alanine aminotransaminase (ALT, aspartate aminotransaminase (AST, alkaline phosphatase (ALP, total cholesterol (TC, triglyceride (TG and creatinine kinase (CK-MB along with heart weight index and antioxidant enzymes was considered to determine the cardioprotective property. Histopathological study was also carried out on heart of experimental animals. The CGO peel extract was found to contain alkaloids, flavonoids, steroids and triterpenoids, saponins, phenolic compounds and tannin as chemical constituents. Cyclophosphamide (CYP and doxorubicin (DOX treated groups exhibited significant increase in LDH, ALT, AST, ALP, TC, TG and CK-MB level and decrease in catalase (CAT, superoxide dimutase (SOD when compared to control group. Pretreatment with different doses of CGO significantly reduced the serum biomarkers and increased the tissue antioxidant level when compared to DOX and CYP alone treated groups. Moreover, treatment with CGO also improved CYP induced changes in histopathology of heart which may be due to its antioxidant property. The Citrus grandis (L. Osbeck exerted protective effect against CYP and DOX induced cardiotoxicity in rats, which may be due its lipid lowering and antioxidant properties. These findings might be helpful to understand the beneficial effects of CGO extract against myocardial injury although further study is needed to confirm its mechanism.

    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 .

    Full Text Available Inflammation is an important feature of many diseases. It is the response of a tissue to an injury, infection, irritation of foreign substance. In fact, it is a part of host defense, but when it is severe, it may be far worse than the diseases itself and in extreme condition, it may be too fatal also. There is an increasing demand for the medicinal plants in developing countries like India. Attention has to be given to assess the medicinal value of such plants to explore the potential drugs out of it. The aim of the study was to investigate acute anti-inflammatory activity of ethanolic extract of the leaves of Clerodendrum viscosum (EELCV by carrageenin induced paw oedema in Wistar Albino rats. Dried powdered leaves of Clerodendrum viscosum were subjected to soxhlet extraction by using 90% ethanol. Based on acute oral toxicity study according to Organization for Economic Cooperation and Development (OECD guidelines No. 423, three doses of the test drug were selected (75, 150 and 300 mg/kg p.o. Oral administration of EELCV at doses of 150 and 300mg/kg showed significant (p<0.01 and moderately significant acute anti-inflammatory activity (p<0.05 respectively by carrageenin induced paw oedema in Wistar Albino rats compared to control.

    Full Text Available Background/Aim: Gastro duodenal ulcer is a common disorder of the gastrointestinal tract. Several Indian medicinal plants have been traditionally and extensively used to prevent different diseases. In the present research studies, Bael fruit (Aegle marmelos (AM, family: Rutaceae which are also called as Bilva in ancient Sanskrit was used as a herbal drug and its antioxidative role in aspirin- induced gastroduodenal ulceration in albino rat was evaluated using essential biochemical parameters. Patients and Methods: Mucosal thickness (MT, ulcer index (UI, different biochemical parameters, such as aspartate aminotransferase (AST, alanine aminotransferase (ALT, catalase (CAT, superoxide dismutase (SOD, reduced glutathione (GSH, and lipid peroxidation (LPO were measured in all the groups, to study the possible involvement of antioxidants with gastroduodenal protection. Results: A significant decrease in MT, SOD and CAT activities and GSH level and a significant increase in UI, AST, ALT, and ALP activities and LPO level were observed in aspirin treated stomach and duodenum of albino rats. Conclusions: Pretreatment with AM fruit pulp extract for 14 consecutive days showed the reverse effects of aspirin suggesting gastro-duodenal protective and anti- ulcerogenic properties of AM through its antioxidant mechanism.

  3. Isolation and sequence of a cDNA clone for human tyrosinase that maps at the mouse c-albino locus

    International Nuclear Information System (INIS)

    Screening of a λgt11 human melanocyte cDNA library with antibodies against hamster tyrosinase resulted in the isolation of 16 clones. The cDNA inserts from 13 of the 16 clones cross-hybridized with each other, indicating that they were form related mRNA species. One of the cDNA clones, Pmel34, detected one mRNA species with an approximate length of 2.4 kilobases that was expressed preferentially in normal and malignant melanocytes but not in other cell types. The amino acid sequence deduced from the nucleotide sequence showed that the putative human tyrosinase is composed of 548 amino acids with a molecular weight of 62,610. The deduced protein contains glycosylation sites and histidine-rich sites that could be used for copper binding. Southern blot analysis of DNA derived from newborn mice carrying lethal albino deletion mutations revealed that Pmel34 maps near or at the c-albino locus, the position of the structural gene for tyrosinase

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

  6. Antiulcer effects of aqueous extract and a fraction of phyllanthus embelic fruit on gastric acid secretion and mucosal defence factors in albino rats

    International Nuclear Information System (INIS)

    Phyllanthus emblica (Euphorbiaceae) fruit has been empirically used since centuries in folkloric medicine to treat gastrointestinal disorders including the gastric ulcers. In the present study, anti-ulcerogenic properties of the fruit, its aqueous extract and a purified fraction were determined in albino rats. Aqueous extract of the fruit protected rats against gastric ulcers induced by indomethacin. Partition of the water extract yielded fractions for which anti-ulcerogenic activity evaluation studies were conducted to find out the most effective fraction. Thin layer chromatography yielded the most purified active fraction, which was found to exert anti-ulcerogenic activity in the chemically induced and stress-induced gastric ulcers in albino rats. In addition, effect of the purified fraction on gastric secretion volume, pH, acid output, ulcer index, mucus secretion and peptic activity revealed it to be the most potent anti-ulcer fraction with efficacy comparable to the reference drug, famotidine. It may be suggested that anti-ulcerogenic activities of P. emblica fruit, Its aqueous extract and the purified fraction could be due to elevation of gastric mucus secretion and inhibition of gastric acid secretion.

    Full Text Available Sepsis is an imbalance between pro and anti-inflammatory responses. Sepsis induced multiple organ failure that is associated with mortality is characterized by liver, renal, cardiovascular and pulmonary dysfunction and reactive oxygen species (ROS are believed to be involved in the development of sepsis. Plant polyphenols may act as antioxidants by different mechanisms such as free radical scavenging, metal chelation and protein binding. Data indicates possible beneficial effects of plant derived phenolic compounds against sepsis. Rosmarinic acid (RA (α-O-caffeoyl-3,4-dihydroxyphenyllactic acid is a phenolic compound commonly found in various plants such as Rosmarinus officinalis (rosemary, Origanum vulgare (oregano, Thymus vulgaris (thyme, Mentha spicata (spearmint, Perilla frutescens (perilla, Ocimum basilicum (sweet basil and several other medicinal plants. It has been shown that RA has many biological activities including antioxidant, anti-inflammatory, antiallergic, anticancer and actimicrobial and is widely used in cosmetic and food industry. In the present study, we aimed to determine the protective effects of RA against the oxidative DNA damage induced by sepsis in Wistar albino rats. The rats were divided into four groups; sham, sepsis induced, RA-treated, RA treated and sepsis induced groups. Wistar rats were subjected to sepsis by cecal ligation puncture. The liver tissues were carefully dissected from their attachments and totally excised. The concentrations of the hepatic tissue cells were adjusted to approximately 2 x 106 cells/ml. Standard and formamidopyrimidine-DNA glycosylase (Fpg modified comet assay described by Singh et al were used. There were no statistically significant differences in terms of tail length, tail intensity and tail moment between the sham group and the RA-treated groups (p>0.05. The DNA damage was found significantly higher in the sepsis-induced group compared to the sham group (p0.05, and the DNA damage

    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

    Probiotic supplementation during critical windows of gestation might have a significant influence on the infant's immune phenotype. Swiss albino mice (F0 generation) aged 31 days were supplemented orally with probiotic Lactobacillus rhamnosus GG (LGG); and the supplementation was continued throughout mating, gestation and lactation. The pups (F1 generation) born to them were separated post weaning and received either the same probiotic supplementation as their mothers or were denied supplementation postnatally. Neutrophil phagocytic ability, splenocyte proliferation, immunoglobulins and cytokines were determined in both F0 and F1 pups. In addition, antibody response against hepatitis-B surface antigen (HBsAg) was determined in F1 pups. Probiotic supplementation had no effect on the neutrophil phagocytic ability and splenocyte proliferation index. The serum immunoglobulin G (IgG) and secretory IgA (s-IgA) among the probiotic supplemented group of F0 generation were significantly (P<0.05) higher compared to the controls. Similarly, the mean concentration of interleukin (IL)-10, IL-17 and interferon gamma (IFN-γ) among F0 probiotic group were significantly higher (P<0.05) compared to the control. Prenatal and postnatal probiotic supplementation in F1 pups led to similar results as F0 dams. Prenatal probiotic supplementation in F1 pups led to significantly (P<0.05) higher serum IgG (55.15±1.35 ng/ml) and intestinal s-IgA (77.9 ± 2.86 ng/mg protein) concentration when compared to the control. Similarly, IFN-γ concentration increased (P<0.05) with prenatal probiotic supplementation compared to the control. However, IL-10 and IL-17 concentrations of prenatal probiotic supplemented F1 pups were comparable to the control. As for the antibody response to HBsAg, prenatal probiotic supplementation led to enhanced HBsAg antibody response (471.4±3.97 U/ml) compared to the control. LGG affected the immune regulation and immune responses favourably in mothers and offspring

  10. The radiomodifying efficacy of beta carotene rich plant extracts on neuroethology of Swiss albino mice: perception, perspectives and risk assessment

    International Nuclear Information System (INIS)

    Full text: High utilization of O2 and rather poorly developed antioxidative defence mechanism makes the brain highly susceptible to oxidative damage. High enrichment with PUFA also renders it susceptible to radiation damage by free radicals. The pure form of beta carotene has proved quite effective against radiation but only at optimum dose level when tested for survivability and lipid peroxidation, protein, cholesterol, DNA content of brain. This induced us to extend our investigation on plants, Amaranthus and Spinach enriched with beta carotene, which could be recommended in the nutritional dietary course without causing psychological stress of availability and affordability unlike of tablets of medicines. Both Amaranthus paniculatus and Spinacea oleracea, commonly occurring weeds have good nutritive values due to their carotenoid, vitamin C, folate, folic acid contents; additionally Amaranthus with high level of lysine and methionine. Swiss albino male mice of 6-8 week(22±3 gm)selected from an inbred colony were administered with alcoholic extract at a dose of 600-mg/kg-body weight/day dissolved in distilled water with and without prior to irradiation (5 Gy of gamma radiation). The animals were studied on 1, 3, 7, 15, and 30 days after radiation exposure. On the basis of LD50/30 values the DRFs were computed as 1.43(AE) and 1.39(S.E). The plant extracts improved learning performance in mice in with and without rradiation. Male mice showed better learning performance as compared to females in all the groups. The brain showed that the radiation induced depletion of protein, glutathione and cholesterol and histopathology was significantly compensated/defied and was brought to near-normal level by the 15 days oral administration of crude extract of the plants. Radiation induced augmentation in glycogen, cholesterol and lipid peroxidation products were significantly checked. The protection appears to be afforded by combined or synergistic effects of plants leaves

    Full Text Available Background: Liver plays a major role in detoxification and excretion of many endogenous and exogenous compounds. Any injury may lead to severe liver damage and impairment of liver function. Harbal plants such as Terminalia chebula (Haritaki may have free radical scavenging activity thereby can be used for the prevention and treatment of liver damage. Objective: To observe the effect of Terminalia chebula on paracetamol induced changes of serum aspartate aminotransferase (AST and alanine aminotransferase (ALT in Wister albino rats. Methods: This experimental study was carried out in the Department of Physiology, Dhaka Medical College, Dhaka from January to December’ 2013. Total 44 rats with age 90 to 120 days, weighing between 150 to 200 gm were selected. After acclimatization for 14 days, they were divided into base line control (BC, n=11, paracetamol treated control (PC, n=11,Terminalia chebula pretreated and paracetamol treated (TCP-PCT n=11 and paracetamol pretreated and Terminalia chebula treated group (PCP-TCT, n=11. All groups received basal diet for 21 consecutive days. In addition to basal diet, rats of BC received propylene glycol (2ml/kg body weight, orally and PC received single dose of paracetamol suspension (750mg/kg body weight, orally on 21st day. Rats of TCP-PCT received Terminalia chebula extract (200 mg/kg body weight, orally for 21 consecutive days and paracetamol suspension (750mg/kg body weight, orally on 21st day.

    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

    Full Text Available Background: Spleen is a secondary lymphoid organ that is highly sensitive to different chemicals. Toluene is an aromatic hydrocarbon commonly used as an industrial solvent and can be considered as a potential immunotoxin. Aims and Objects: We aimed to investigate the organometry and histology of spleen from rats exposed to toluene. Materials and Methods: The toxicity of toluene was evaluated in male albino rats (6/group via whole-body exposure. The animals were exposed to target concentrations of 0 (air control and 133 parts per million (ppm of toluene in air for 5 hours/day, 5 days/week, for 2 month. The animals were weighted and decapitated at different time points (one, seven, sixteen, thirty one and sixty one day post-exposure. The weight, length, width and thickness of the spleen were measured. It was studied absolute and relative weight of the spleen. Histological examination of the spleen was made by light microscope. Results: Statistically significant difference between the mean of body weight from the control and experimental animals was observed seven days after last exposure to toluene. Thus, the body weight of animals exposed to toluene was 254.17 g, that was 7.18% (p = 0.048 below control data. The histological findings showed increased area of the white pulp of spleen from rats exposed to toluene had increases compared to that from the control. The numbers of siderophages were higher in the spleen from rats exposed to toluene. The relative area of germinal centre in the structure of the splenic lymph follicles of rats exposed to toluene increased. We found that in the first and second experimental groups of animals the indication was at the level 10.86% and 10.26% respectively. These are 24.11% (p = 0.002 and 26.04% (p <0.001 above control data, respectively. Inhalation exposures to toluene vapor at 133 ppm produces hyperplasia of lymphoid tissue of the rat spleen.

    One of the major problems faced in the modern world today is that of pollution caused due to radioactive material and emission of gamma radiation from various sources either in terms of background radiation sources, accidental leak from nuclear reactors or intentional convert attack by terrorists to achieve the malefic goals. In view of such perceived risks and threats associated with plausible radiological and nuclear incidents. It is pertained to develop potential drugs for the mitigation of deleterious effects of ionizing radiation and heavy metals. In recent years, immense interest has been developed in the field of chemoprotection against radiation and heavy metal induced changes. In light of above the present study was aimed to evaluate the protective efficacy of Emblica officinalis against Radiation and cadmium induced biochemical alteration in the Brain of Swiss Albino mice. The animals were exposed to 3.0 Gy of gamma rays with or without cadmium chloride treatment. The Emblica extract was administered seven days prior to irradiation or cadmium chloride treatment. The animals from all the experimental groups were sacrificed by cervical dislocation at each post-treatment interval of 1, 2, 4, 7, 14 and 28 days. After sacrificing the animals, mid brains (cerebral hemisphere) were taken out and kept at -20 deg C for different biochemical parameters.

    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

    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.

    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

    Full Text Available Malaria remains one of the leading public health diseases in developing countries and efforts to keep the infection at bay have suffered a lot of setbacks compounded by the increasing cases of resistance and cross resistance to firstline antimalaria drugs. In this study, we investigated the anti-plasmodial efficacy of ethanolic and aqueous extracts of Nicotiana tabacum on Plasmodium berghei infected swiss albino mice and its effects on liver and kidney function. The comparison of changes in parasite load of the infected mice before and after treatment showed that the parasitemia level reduced significantly (p0.05. However, the concentration of urea was statistically higher in treated groups than the control (p<0.05. Our results therefore demonstrate the anti-plasmodial potential of N. tobacum and its relative safety for human consumption at the tested doses.

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

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

  7. Effects of canola oil supplemented with atherogenic element and nigella sativa (kalonji) on serum lipids in albino rats - an experimental study

    International Nuclear Information System (INIS)

    To compare effects of canola oil supplemented with atherogenic element and Nigella sativa on serum lipids in albino rats. Place and Duration of Study: Study was conducted at Pathology Department of Postgraduate Medical Institute, for 12 weeks. Study Design: Laboratory based randomized controlled trials. Material and Methods: Seventy two albino rats were selected and randomly divided into six groups of twelve animals with equal number of male and female in each. Fourteen days after acclimatization to the environment and basal diet, fasting blood samples (zero week) were collected by heart puncture under ether anesthesia and experimental diets were started which were continued for 12 weeks. All parameters were measured using enzymatic colorimetric methods. Results: Estimations of serum lipids showed increase in total cholesterol (TC) and High Density Lipoprotein Cholesterol (HDL-c) levels but fall in LDL-c concentrations in groups fed on canola oil diet. On the other hand, even atherogenic supplemented groups had decrease in cardio-protective HDL-c and raised LDL-c; although statistically non-significant. Thus canola oil diets were not hyperlipidaemic and prevented adiposity. Nigella sativa (NS) diets significantly decreased serum total cholesterol and LDL-c while HDL-c was raised but non-significantly. Thus Nigella sativa prevented deposition of lipids in tissues, thus preventing tendency to obesity and atherogenesis by decreasing LDL-c in serum. Conclusion: Nigella sativa produces antilipidaemic and anti-obesity effects by decreasing low density lipoprotein cholesterol level which is statistically significant in two out of the three groups fed on Ns; it also increased high density cholesterol which was however non-significant in comparison with Canola oil alone.

    Objective: The present study was undertaken to investigate the effect of long dose administration of methanol rhizome extract of Podophyllum hexandrum and hydrogen peroxide on lipid peroxidation of erythrocytes, antioxidant enzyme status of rat liver, kidney, lung and brain tissue and body weight and organ weight changes of albino rats. Methods: The body and organ weight was monitored with digital scale balance and lipid peroxidation of RBC ghost membrane was monitored by measuring malonaldehyde (MDA). Antioxidant enzymes were assayed by standard procedures. Results: Our study showed that administration of H2O2 (0.1%) in drinking water of the rats for 25 weeks increased the malondialdehyde levels in erythrocytes of all the rats. However, rats receiving Podophyllum hexandrum extract and α- tocopherol had lower MDA levels in a dose dependent manner, which indicates decreased lipid peroxidation in these rats. Our results also showed decrease in the activity of glutathione reductase, glutathione-S-transferase and reduced glutathione levels in different organs of H2O2 treated rats. Rats receiving methanolic extract of Podophyllum hexandrum at the concentration of 5, 10 and 15mg% for 25 weeks increased the activity of glutathione reductase, glutathione-S-transferase and glutathione levels in different organs of the rats indicates the protective effect of the plant in combating oxidative stress undergone by the rats. No significant variation (P< 0.05) in the organ weights between the control and the treated groups was observed after 25 weeks of treatment. Conclusions: In conclusion, this study presents strong evidence of the nontoxic effect of the methanol extract of Podophyllumhexandrum. The findings also demonstrate that Podophyllum hexandrum methanol extract increased the levels of antioxidant enzymes and decreased lipid peroxidation in albino rats and explained the extensive utilization of the plant in traditional medicine.

    Full Text Available O presente trabalho tem por objetivo o estudo da eficácia comparativa de diferentes vias de infecção na equistossomose experimental do camundongo albino. Foram utilizados trinta camundongos albinos de ambos os sexos, com idade de dois meses, infectados com cerca de cem cercárias cada um e sacrificados três meses após a infecção. As vias de penetração empregadas foram: oral, transcutânea (por submersão parcial, imersão apenas da cauda e/ou colocação de cercárias em área depilada do abdômen e intraperitoneal. Os resultados obtidos demonstraram que a via mais eficaz foi transcutânea (sub-parcial, e que a maior mortalidade ocorreu no grupo infectado por via intraperitoneal.The comparative efficiency for different infecting routes in experimental schistosomiasis in Swiss albino mice has been studied. Thirty mice, both male and female, two months old, have been each infected with one humdred Schistosoma mansoni cercariae, and sacrificed three months later. The following infecting routes have been used: oral, percutaneous (partial body submersion, tail imersion and dropping of water containg cercariae on a shaved area of the anterior abdominal wall, and intra-peritoneal routes. Per-cutaneous route (partial submersion of the body proved to be the best and the highest mortality occurred in animais intra-peritoneally infected.

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

    International Nuclear Information System (INIS)

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

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

    Hairless albino Crl:SKH1-Hr(hr) mice are commonly utilized for studies in which hair or pigmentation would introduce an impediment to observational studies. Being an outbred strain, the SKH1 model suffers from key limitations that are not seen with congenic mouse strains. Inbred and congenic C57BL/6J mice are commonly utilized for modified genetic mouse models. We compare the acute UV-induced photoresponse between outbred SKH1 mice and an immune competent, hairless, albino C57BL/6J congenic mouse line [B6.Cg-Tyr(c-2J) Hr(hr) /J]. Histologically, B6.Cg-Tyr(c-2J) Hr(hr) /J skin is indistinguishable from that of SKH1 mice. The skin of both SKH1 and B6.Cg-Tyr(c-2J) Hr(hr) /J mice exhibited a reduction in hypodermal adipose tissue, the presence of utricles and dermal cystic structures, the presence of dermal granulomas and epidermal thickening. In response to a single 1500 J/m(2) ultraviolet B dose, the oedema and apoptotic responses were equivalent in both mouse strains. However, B6.Cg-Tyr(c-2J) Hr(hr) /J mice exhibited a more robust delayed sunburn reaction, with an increase in epidermal erosion, scab formation and myeloperoxidase activity relative to SKH1 mice. Compared with SKH1 mice, B6.Cg-Tyr(c-2J) Hr(hr) /J also exhibited an aberrant proliferative response to this single UV exposure. Epidermal Ki67 immunopositivity was significantly suppressed in B6.Cg-Tyr(c-2J) Hr(hr) /J mice at 24 h post-UV. A smaller non-significant reduction in Ki67 labelling was observed in SKH1 mice. Finally, at 72 h post-UV, SKH1 mice, but not B6.Cg-Tyr(c-2J) Hr(hr) /J mice, exhibited a significant increase in Ki67 immunolabelling relative to non-irradiated controls. Thus, B6.Cg-Tyr(c-2J) Hr(hr) /J mice are suitable for photobiology experiments. PMID:27095432

    Tyrosinase is a key enzyme in melanin biosynthesis. Mutations in the gene encoding tyrosinase (Tyr) cause oculocutaneous albinism (OCA1) in humans. Alleles of the Tyr gene have been useful in studying pigment biology and coat color formation. Over 100 different Tyr alleles have been reported in mice, of which ≈24% are spontaneous mutations, ≈60% are radiation-induced, and the remaining alleles were obtained by chemical mutagenesis and gene targeting. Therefore, most mutations were random and could not be predicted a priori. Using the CRISPR-Cas9 system, we targeted two distinct regions of exon 1 to induce pigmentation changes and used an in vivo visual phenotype along with heteroduplex mobility assays (HMA) as readouts of CRISPR-Cas9 activity. Most of the mutant alleles result in complete loss of tyrosinase activity leading to an albino phenotype. In this study, we describe two novel in-frame deletion alleles of Tyr, dhoosara (Sanskrit for gray) and chandana (Sanskrit for sandalwood). These alleles are hypomorphic and show lighter pigmentation phenotypes of the body and eyes. This study demonstrates the utility of CRISPR-Cas9 system in generating domain-specific in-frame deletions and helps gain further insights into structure-function of Tyr gene. PMID:27224051

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

    To evaluate the efficacy of cardamom with pioglitazone on dexamethasone-induced hepatic steatosis, dyslipidemia, and hyperglycemia in albino rats. There were four groups of 6 rats each. First group received dexamethasone alone in a dose of 8 mg/kg intraperitoneally for 6 days to induce metabolic changes and considered as dexamethasone control. Second group received cardamom suspension 1 g/kg/10 mL of 2% gum acacia orally 6 days before dexamethasone and 6 days during dexamethasone administration. Third group received pioglitazone 45 mg/kg orally 6 days before dexamethasone and 6 days during dexamethasone administration. Fourth group did not receive any medication and was considered as normal control. Fasting blood sugar, lipid profile, blood sugar 2 h after glucose load, liver weight, liver volume were recorded, and histopathological analysis was done. The effects of cardamom were compared with that of pioglitazone. Dexamethasone caused hepatomegaly, dyslipidemia and hyperglycemia. Both pioglitazone and cardamom significantly reduced hepatomegaly, dyslipidemia, and hyperglycemia (P cardamom (P Cardamom has comparable efficacy to pioglitazone in preventing dexamethasone-induced hepatomegaly, dyslipidemia, and fasting hyperglycemia.
