The toxicity of various forms of mercury to the living organisms is well documented. Mammalian kidney is the main site of decomposition of inorganic mercury as well as the target organ for its toxicity in majority of the animals including human beings. Present study has been aimed to investigate the role of Tageteserecta(family-Astereacea) as a possible modifier of mercury induced renal damages. Experimentation was conducted on one hundred female albino rats, divided into five equal groups, each group again sub-divided into four sub-groups having five rats each: Control group- Orally administrated distilled water only. T. erecta flower extract treated group-10mg/kg b. wt./day for 1, 7, 14, 21 days was administrated orally. Mercuric chloride treatment groups-A dose of 0.926 mg/kg b.wt. for 01 day, 0.132 mg/kg b.wt. for 7 days, 0.066 mg/kg b.wt. for 14 days and 0.044 for 21 days was administrated through oral route. Oral administration of T. erecta flower extract followed by mercuric chloride treatment for 1, 7, 14 and 21 days. Oral administration of Mercuric chloride followed by T. erectaflower extractadministration for 1, 7, 14 and 21 days. These animals were then sacrificed after 1, 7, 14 and 21 days treatment respectively. Controls were also run respectively. Mercuric chloride intoxication resulted in pathological alterations in the kidney of albino rats, such as degradation of glomerulus, proximal and distal tubules. Combined pre and post treatment of T. erectawith mercuric chloride has been found to reduce the pathological alterations in the kidney. Thus, the results from the present study suggest that T. erectacan modify the renal damages against mercuric chloride induced toxicity.

AbstractObjectivesAluminium is present in food preparations, antacids and many medications. It causes neurodegeneration thereby resulting in a spectrum of neurological disorders such as dementia, Alzheimer’s disease and anxiety. Bacopa monnieri (BM) is widely used in ayurvedic medicine to improve memory functions. Its anxiolytic property was investigated in this study by using elevated plus maze (EPM) and plasma corticosterone level.MethodsThirty rats were assigned into five groups. Control group received distilled water, and 0.5% tween 80, AlCl3 group received Aluminium Chloride (AlCl3), Protective groups (BM100 + AlCl3 group and BM200 + AlCl3 group) received AlCl3 and BM at two different doses, and the BM200 group received BM. The EPM experiment was performed at the end of the 4th week of oral administration of BM and AlCl3 followed by the measurement of plasma corticosterone.ResultsOral administration of AlCl3 to rats increases the levels of anxiety as seen in a decrease in the percentage of entries into the open arms of EPM, an increase in grooming frequency and defecation index. However, the rats in the protective groups shown an increase in the percentage of open arm entries and rearing frequency, and decreased grooming frequency and defecation index. AlCl3 alone treated group showed a significant increase in the plasma corticosterone levels compared to the control group. Whereas the protective groups have shown a significant decrease in the plasma corticosterone levels than the AlCl3 alone treated group.ConclusionsHence the BM has potential role in reverting the anxiogenic effect of AlCl3 in the amygdala as it is evident from the plasma corticosterone levels and the EPM parameters of different groups under study.

Purpose: The present study aimed to assess functional and structural benefits of erythropoietin (EPO) when administered subconjunctivally in the retina of glaucomatous rats using electroretinography (ERG) and retinal thickness (RT) measurements. Methods: Glaucoma was experimentally induced in 26 Wistar Hannover albino rats. Animals were divided into 2 groups of 13 animals each: a treated group receiving a unique subconjunctival injection of 1,000 IU of EPO and a control group receiving a saline solution. In each group, 7 animals were used for retinal function evaluation (ERG) and 6 animals were used for retinal structural evaluation (histology). RT was measured, dorsally and ventrally, at 500 μm (RT1) and at 1,500 μm (RT2) from the optic nerve. Results: Retinal function evaluation: for both scotopic and photopic conditions, ERG wave amplitudes increased in the treated group. This increase was statistically significant (p < 0.05) in photopic conditions. Structural evaluation: for both locations RT1 and RT2, the retinas were significantly (p < 0.05) thicker in the treated group. Conclusion: Subconjunctival EPO administration showed beneficial effects both on retinal structure and on retinal function in induced glaucoma in albino rats. This neuroprotective effect should be applied in other animal species.

Mercury is a harmful toxic pollutant, which has hepato-nephrotoxic, hematotoxic, genotoxic and neurotoxic, effects. The aim of the study was to evaluate the protective efficacy of wheatgrass on mercuric chloride (HgCl2) induced oxidative stress and associated complications in rat model. Albino rats were divided into four groups (three rats per group). Group I normal control group. Group II oxidative stressed group received mercuric chloride (0.5 mg/kg/day). Group III only received wheatgrass extract (100 mg/kg/day), whereas Group IV received wheatgrass (100 mg/kg/day) after one hour, followed by mercuric chloride (0.5 mg/kg/day) for 30 days. The results of the study showed that wheatgrass supplementation significantly decreased the HgCl2 induced elevated oxidative stress parameters Plasma Malondialdehyde (MDA) content, Plasma membrane redox system (PMRS), Advanced oxidation protein products (AOPP), simultaneously elevated lipid profile (Total Cholesterol, Triglycerides, Low-density lipoprotein (LDL), liver enzymes as, Plasma Alkaline phosphatase (ALP), Aspartate aminotransferase (AST), and Alanine aminotransferase (ALT), Serum Urea, and Creatinine levels in rats. In addition, wheatgrass treatment improved the antioxidant status in terms of intracellular Reduced Glutathione (GSH), Ferric reducing antioxidant power (FRAP) and 2, 2- diphenyl -1- picrylhydrazyl (DPPH). Therefore it can be concluded that wheatgrass has great potential to diminish the stress-mediated complications and improve the antioxidant status.

Tramadol is a synthetic, centrally acting analgesic. It is the most consumed narcotic drug that is prescribed in the world. Tramadol abuse has dramatically increased in Egypt. Long term use of tramadol can induce endocrinopathy. So, the aim of this study was to analyze the adrenal insufficiency induced by long term use of tramadol in experimental animals and also to assess its withdrawal effects through histopathological and biochemical genetic study. Forty male albino rats were used in this study. The rats were divided into 4 groups (control group, tramadol-treated group, and withdrawal groups). Tramadol was given to albino rats at a dose of 80 mg/kg body weight for 3 months and after withdrawal periods (7–15 days) rats were sacrificed. Long term use of tramadol induced severe histopathological changes in adrenal glands. Tramadol decreased the levels of serum cortisol and DHEAS hormones. In addition, it increased the level of adrenal MDA and decreased the genetic expression of glutathione peroxidase and thioredoxin reductase in adrenal gland tissues. All these changes started to return to normal after withdrawal of tramadol. Thus, it was confirmed that long term use of tramadol can induce severe adrenal insufficiency.

The declining rate of male fertility is a growing concern. Tributyltin (TBT) is a well-known endocrine disruptor (ED), that induces imposex in female gastropods and is widely used in various industrial applications. The aim of this study was to evaluate the toxic effects of TBT on the testes of adult albino rats and the possible role of omega-3. Forty two adult male albino rats were divided into five groups; control group (Group I) and four experimental groups: omega-3 treated group, TBT treated group, TBT & omega-3 treated group and follow up group. At the end of the study, the rats were subjected to biochemical, histological, immunohistochemical staining for Ki-67 and seminal examinations. Our results clarfied that TBT induced a significant decrease in testosterone, FSH, LH and serum glutathione peroxidase levels and a significant increase in the serum Malondialdehyde as compared to the control group. Tributyltin induced disorganization and shrinkage of seminiferous tubules, apoptosis, cellular damage and marked reduction in the germinal epithelium. A significant decrease in the cell proliferation and arrested spermatogenesis were also detected. Seminal analysis of TBT group showed a significant affection of all parameters as compared to other groups. Omega-3 ameliorated all of these hazardous effects. Follow up group still showed toxic effects. In conclusion, TBT has a toxic effect on the testis. Increased testicular oxidative stress, cellular damage and arrest of spermatogenesis with attenuation in antioxidant defenses are all contributing factors. Omega-3 can protect against TBT induced reproductive toxicity.

This study was designed to investigate the electrophysiological, hemodynamic and biochemical parameters of mercuric chloride and methylmercury exposure on cardiovascular functions and its modulation by melatonin in vivo. Wistar albino rats were divided into six group containing 10 animals each. Mercuric chloride (3.75 µM/L) in drinking water and methylmercury (0.5 mg/kg/day) through gavage, given for 1 month, induced a statistically significant increase ( p < 0.001) in left ventricular end diastolic pressure, blood and cardiac tissue mercury content and myocardial lipid peroxides compared to control. Significant attenuation ( p < 0.05) of baroreflex sensitivity and depletion of myocardial endogenous antioxidants ( p < 0.001) viz. Reduced glutathione (GSH) and superoxide dismutase (SOD) were also found in the mercury-exposed groups as compared to control group. Mercury exposure followed by subacute treatment with melatonin (4 µg/mL/day) in drinking water for 1 month significantly lowered ( p < 0.01) left ventricular end diastolic pressure and lipid peroxide levels and increased baroreceptor sensitivity ( p < 0.001) and also levels of GSH and SOD ( p < 0.001) as compared to mercury-exposed rats. The results of our study provide clear evidence that elevated oxidative stress and altered baroreflex mechanisms caused by mercury intoxication may be the contributing factors responsible for impairment of cardiovascular functions and melatonin may exhibit cardioprotective property against subacute heavy metal intoxication and enhance the antioxidant defense against mercury-induced oxidative myocardial injury in rats.

The present study aimed to investigate the ameliorative effects of fenugreek seeds and curcumin on hematotoxicity induced by nicotine in male albino rats. 30 male F-344/NHsd Fischer rats, weighing from 180 to 200g were used in the present study. The animals were divided into five groups (6 rats for each); Group I (control group), Group II (nicotine treated group), Group III (nicotine/fenugreek seeds co-administered), Group IV (nicotine/curcumin co-administered), and Group V (nicotine/curcumin& fenugreek seeds co-administered). At the end of the experimentation and 24 hours after the last dose, all animals were anaesthetized with ether and blood samples were collected by heart puncture. The samples were collected in clean dry tubes containing the anticoagulant substance EDTA and used for the hematological studies. The results showed that the animals treated with nicotine for 4 weeks showed a significant decrease in RBCs count, hemoglobin concentration, hematocrit value, MCH, MCHC, and platelets count, and increased MCV and WBCs count as compared to the control group. Co-administration of nicotine with fenugreek and/or curcumin caused improvement in all hematological parameters when compared with nicotine group. It can be concluded that nicotine had a strong effect on the hematological parameters. The ingestion of fenugreek and/or curcumin prevent the hematoxicity induced by nicotine. The current study suggests that fenugreek and curcumin may be useful in combating free radical-induced hematotoxicity induced by nicotine.

Objective: To determine the anti-hyperglycemic effects of interleukin-1 inhibitor (diacerein) in alloxan induced diabetic albino wistar rats. This experimental study was performed at the Department of Animal Husbandry and Veterinary Sciences, Sindh Agriculture University, Tando Jam within 6 months from April 2016 to September 2016. Total of 160 adult Albino Wistar Rats having an average of 200 to 300 grams body weights were selected. Animals were categorized into 4 groups as; Group A (n=15): Control rats – receive 0.9% normal saline as placebo Experimental Groups Group B (n=15): Experimental Control (Diabetic rats) - Alloxan50 mg/kg body weight intraperitoneal. Group C (n=15): Diabetic rats + Diacerein (30 mg/kg/day) orally daily. Group D (n=15): Diabetic rats + Diacerein (50 mg/kg/day) orally daily. Animals were kept and treated as per the NIH Guideline for Use and Care of Laboratory Animals. Diabetes mellitus was induced via a single intraperitoneal injection of 50 milligram/kg alloxan monohydrated dissolved in aseptic 0.9% saline. After 72 hours, blood specimens were taken from the caudal vein of the rats and glucose level>200 mg/dL was taken as diabetes. Experimental rats were given diacerein approximately 30 and 50 mg orally for 6 weeks. At the completion of experiment the body weight was measured of each animal by electronic measuring balance and blood sample was taken from each animal of all groups to assess the blood glucose level and HbA1c level. Data were recorded via self-made proforma and analysis was done by using SPSS version 20. Results: Average body weight of Diabetic control (Group B) was 193.33±22.50 grams, which was lower in contrast to Diacerein treated group C 202.47±25.70 grams and significantly lower as compared to Diacerein treated group D as  212.6±23.43 grams. A significant increase in blood glucose levels 182.07±10.63 mg/dl was noted in the Diabetic control (Group B) compared to Diacerein treated group C (110.13± 8.54 mg/dl) and group D (85.87±8.41 mg/dl) (P=0.001). HbA1c was markedly raised in the Group B- diabetic controls, while diacerein treated diabetic rats (groups C and D) showed a significant decrease in HbA1c (P=0.001). Conclusion: It was concluded that Diacerein achieves the Euglycemic state by reducing the levels of blood glucose and glycated hemoglobin (HbA1c) in Alloxan-Induced diabetes mellitus in Wistar Albino Rats.

Combretum collinum root extract has been recognized long ago as traditional medicinal plant in curing several diseases among the indigenous people of Alela-land (Zuru), Kebbi State, Nigeria. This research work was carried out to evaluate the toxicological effects of Combretum collinum methanol root extract (CCME) in albino rats. Acute toxicity was performed by a fixed single oral administration at a dose of 10, 100, 1000 mg/Kg and 1600, 2900, 5000 mg/Kg. Subchronic toxicity studies of CCME was conducted at doses of 32, 63, 126 and 253 mg/Kg for 28 days. The result showed that acute administration of CCME resulted at mortality and general behavioral changes at 1000 to 5000 mg/Kg. Therefore, the estimated lethal dose (LD50) of CCME was 316.23 mg/Kg. Subchronic oral administration of CCME revealed a significant (P<0.01) decrease in body weight in rats receiving 63 to 253 mg/Kg throughout the study period compared with the control group. The results also showed a significant (P<0.01) increase in serum ALT, AST, creatinine, potassium and bicarbonate in rats administered with 126 and 253 mg/Kg of the extract. Haematological analysis of the same extract revealed a significant (P<0.01) increase in WBC, HCT, MCV, MCH, MCHC, PLT, LYM and NEUT in rats receiving 126 and 253 mg/Kg only. Histopathological examination of liver revealed severe periportal inflammation, hypertrophy, areas of hydropic changes, cancerous tumor, areas of infiltration and necrosis of the hepatic cells while the kidney showed a mild mesengial hyperplasia, compressed blood vessels, glomerular degeneration, tubular degeneration and tubular widened lumen in rats treated with 63 to 253 mg/Kg. Therefore, caution should be applied as C. collinum root extract has a low mean lethal dose and would be toxic at higher concentrations.
