The adverse effect of cypermethrin on the liver and kidney of weanling female rats and the protective effect of ethanolic extract of grape pomace were investigated in the present study. Weanling female rats were given cypermethrin oral at a dose of 25 mg kg−1body weight for 28 consecutive days. An additional two Cyp-trated groups received extract at a dose of 100 and 200 mg kg−1body weight, respectively, throughout the experimental duration. Three groups more served as extract and control groups. Administration of Cyp resulted in a significant increase in serum marker enzymes, for example, aminotransferases (AST and ALT), alkaline phosphatase (ALP), and gamma-glutamyl transferase (GGT), and increases the level of urea nitrogen and creatinine. In contrast, Cyp caused significant decrease in levels of total protein and albumin and caused histopathological alterations in liver and kidneys of female rats. Coadministration of the extract to Cyp-treated female rats restored most of these biochemical parameters to within normal levels especially at high dose of extract. However, extract administration to Cyp-treated rats resulted in overall improvement in liver and kidney damage. This study demonstrated the adverse biohistological effects of Cyp on the liver and kidney of weanling female rats. The grape pomace extract administration prevented the toxic effect of Cyp on the above serum parameters. The present study concludes that grape pomace extract has significant antioxidant and hepatorenal protective activity.

This study aimed to investigate the prophylactic effect of turmeric (Curcuma longa) Rhizome Ethanolic extract (CLRE) at 250 mg/kg as antioxidant effects against penconazole induced sub-acute toxicity. Hepatic, renal and testicular pathological changes caused by oxidative damage induced by penconazole in rats were biochemically and histologically evaluated. Male rats were treated with penconazole, via oral route, at doses of 0.5 mg/ kg body weight (b.w.; acute reference dose, ARfD), 25 mg/kg b.w. (no observed adverse effects level, NOAEL) and 100 mg/ kg b.w. (1/20 lethal dose [LD50]) for 28 consecutive days. Penconazole treatments had significant (p < 0.05) and gradual reductions in body and relative testicular weight accompanied by significant elevation in the relative liver and kidney weights. Significant increase serum aspartate aminotransferase (AST), alanine aminotransferase (ALT), alkaline phosphatase (ALP), lactate dhydrogenase(LDH), gamma-glutamyl transferase (GGT), creatinine (Cre), uric acid and blood glucose was observed due to penconazole treatments. However, total protein and testosterone hormone were significantly decreased. Exposure to penconazole caused increase in lipid peroxidation (LPO) and decreased of liver and kidney antioxidant enzymes activity as catalase (CAT), superoxide dismutase (SOD) and glutathione peroxidase (GPx). Histopathological studies confirmed the ameliorative beneficial effects of turmeric biochemical parameters. On the basis of this study, the use of tumeric rhizomes as a functional food or as a nutraceutical product could be a useful approach to protect individuals who are regularly exposed to penconazole.

Cypermethrin (CM) is an important type II pyrethroid pesticide used extensively in pest control and is reported to cause hepatic and renal toxicity. Oxidative stress and lipid peroxidation (LPO) has been implicated in the toxicology of pyrethroids. Fenugreek is known for its antitoxic and antioxidant potential. We have investigated the protective effect of aqueous extract of germinated fenugreek seeds in CM-induced hepatic and renal toxicity. Male Wistar rats were treated with 1/10 LD50 (25 mg/kg body weight) of CM and 10% aqueous extract of fenugreek (GFaq) for 60 days. CM treatment caused increased thiobarbituric acid reactive substances (TBARS), depletion in glutathione (GSH) and reduction in the activities of superoxide dismutase (SOD), catalase (CAT), glutathione peroxidase (GPx) and glutathione-S-transferase (GST) in liver and kidneys. There was a significant reduction in total phospholipids and increased activities of phospholipases A (PLA) and C (PLC) in liver and kidneys and increased activities of serum marker enzymes, aspartate transaminase (AST), alanine tansaminase (ALT), alkaline phosphatase (ALP), lactate dehydrogenase (LDH) and gamma glutamyl transferase (GGT). Treatment with 10% GFaq showed replenishment of antioxidant status and brought all the values to near normal, indicating the protective effect of fenugreek. Phytochemicals present in fenugreek could play an important role in ameliorating the pesticide-induced toxicity.

The mode of cellular toxicity of aqueous extract of Fadogia agrestis stem in male rats was investigated. Rats were grouped into four: A, B, C and D where A (the control) received orally 1 mL of distilled water; B, C and D (test groups) received orally 18, 50 and 100 mg/kg body weight of the extract, respectively, for 28 days. Infrared spectroscopy indicated the presence of hydroxyl (OH) and primary amine (CONH). Clinical toxicity symptoms such as respiratory distress, epistasis, salivation, hypo- and hyperactivity were not observed at any period of the experiment. No mortality was also recorded. Extract administration significantly reduced (p < .05) the activities of alkaline phosphatase, lactate dehydrogenase and gamma glutamyl transferase in the liver and kidney with corresponding increases in the serum. Serum malondialdehyde also increased significantly in all the extract-treated groups. The liver and kidney body weight ratios of the extract-treated animals compared well (P > .05) with their controls throughout the experimental period. The extract did not cause any swelling, atrophy or hypertrophy of the organs. The other evidence in this study suggests disruption of the ordered lipid bilayer of the plasma membranes of the hepatocytes and nephrons. This might have resulted from peroxidation of the polyunsaturated fatty acids on the membranes of the hepatocytes and nephrons made possible by the functional groups or the product of metabolism of the extract. This may be responsible for the compromise of the integrity of the plasma membranes of the hepatocytes and nephrons.

The aim of this study was was to determine the nutritional requirements of digestible methionine+cystine (M+C) for white-egg layers aged one to six weeks. A completely randomized design with five methionine+cystine levels, six replicates, and 30 birds per experimental unit was adopted. Dietary treatments consisted of five diets supplemented with DL-Methionine with resulted in five levels of digestible methionine + cystine, 80% (0.516%), 90% (0.578%), 100% (0.640%), 110% (0.702%), and 120% (0.764%), based on Brazilian tables of nutritional requirements. Performance, serological blood, and histological data were evaluated. Feed intake, feed conversion, hepatic glycogen deposition, enzymatic activity of alanine aminotransferase and gamma-glutamyl transferase, and serum creatinine and albumin levels had showed a quadratic response to the levels of digestible M+C, with the respective requirements: 89.78% (0.575%), 114.33% (0.732%), 86.50% (0.554%), 100% (0.640%), 100.40% (0.643%), 104.30% (0.668%), and 111.88% (0.716%). Increasing levels of methionine+cystine elevated the relative liver weight and the deposition of hepatic glycogen, in addition to promote higher growth in pullets, with better body weight and body weight gain and feed conversion ratio. Our findings suggest that 0.732% digestible methionine+cystine is recommended, which corresponds to an intake of 151.20 mg/bird/d and a Met+Cys:Lys  ratio 83%, for light pullets from one to six weeks.

Abstract Considering that the involvement of reactive oxygen species (ROS) has been implicated in the toxicity of various pesticides, this study was designed to study the ameliorative effect of Vitamin E (100 mg/kg body weight) on mice (25 - 30 mg) treated with diazinon (32.5 or 16.25 mg/kg body weight) organophosphate insecticide for 14 days. Subchronic DZN exposure and the protective effects of vitamins E (vitE) were evaluated for their effects on haematological indices, the enzymes concerning liver damage [plasma alanine aminotransferase (ALT), aspartate aminotaransferase (AST), alkaline phosphatise (AIP), and some parameters of kidney function (urea and creatinine) in mice. Additionally, the histopathological changes in liver and kidney tissue were examined. The high dose of diazinon (DZNH) decreased the body weight significantly at the end of experiment. Additionally, the liver and kidney were examines for histopathological changes. The high dose of diazinon decreased body weight significantly. Moreover, there was a statistically significant decrease in haemoglobin (Hb), red blood cell (RBC) and hematocrit (Hct) in diazinon-treated mice compared to controls. This decrease was partially remedied in the diazinon-treated group that also received vitE. Damage in the liver and kidney tissues was also evident as elevated plasma ALT, AST, ALP, urea and creatinine. VitE partially counteracts the toxic effect of DZN and repairs tissue damage in the liver and kidney, especially when supplemented to 1/4 LD50 intoxicated animals. Histopathological changes in liver and kidney were observed only in 32.5 mg/kg DZN given group. These results suggest that the effects of DZN are dose dependent. No pathological findings were observed in vitE + DZN treated groups. According to the present study, we conclude that vitE can reduce the detrimental impacts of diazinon on haematological indicies, as well as liver and kidney function.

Animal model development of alcohol administration in rats is of crucial importance as it gives indirect information to effects of alcohol in humans. An indirect assessment of this would be the biochemical and histological data that could arise from such experiments. 20 Male Wistar rats weighing (63.50±3.79 g), were divided into four groups (consisting 15 treated animals and 5 control animals) and administered with varying concentrations of ethanol (5% 15% and 40%) via intragastric intubation for a period of 28 days. Probic evaluations, liver biochemical enzymes and alteration in histology profile of gastrointestinal tract (GIT) and viscera organs (namely the liver, kidney, heart and lungs) were determined after experimental duration. At 40% ethanol administration, the rats showed biochemically significant decrease in serum gamma glutamyl transferase (GGT), serum aspartate (AST) and Alanine amino transferase (ALT) when compared to normal study while 5% and 15% ethanol administered rats were comparable with control values i.e. normal study. Probic evaluations such as body weight, water intake and food intake showed percentage decrease in 40% ethanol administrated rat when compared with controls. The photomicrographs of the 5% and 15% ethanol administered rats indicated mild damage in their histological profiles when compared to the normal study while there was more adverse damage occurring in the 40% ethanol administrated rats. Conclusion: From this study, serum aspartate (AST), gamma glutamyl transferase (GGT) and Alanine amino transferase (ALT), probic evaluation (body weight, food intake and water intake) coupled with histopathological investigation may be used as biomarker for the early diagnosis of ethanol toxicity in human beings.

Aim: Manganese (Mn) is an essential trace element in many cellular processes. However, there is dearth of literature on its influence on indomethacin-induced hepatorenal damage. Therefore, this study was conducted to investigate the effect of manganese on indomethacin-induced hepatorenal damage in rats. Methods: Rats were divided into four groups of eight rats consisting of control group, indomethacin (IND) alone (20 mg/kg), Mn alone (10 mg/kg) and co-treated group that were treated orally for 14 consecutive days. Twenty four hours after treatment, under pentobarbital anesthesia, blood was collected and liver was excised to prepare homogenate and histology staining. Liver and kidney function tests aspartate aminotransferase (AST), alanine aminotransferase (ALT), alkaline phosphatase (ALP), gamma glutamyl transferase (GGT), lactate dehydrogenase (LDH), malate dehydrogenase (MDH), glutamine dehydrogenase (GLDH), sorbitol dehydrogenase (SDH), glucose-6-phosphate dehydrogenase (G6PD), bilirubin (BIL), urea, creatinine, cholesterol (CHOL), triglycerides (TG), low and high density lipoprotein (LDL and HDL), electrolytes and oxidative stress superoxide dismutase (SOD), catalase (CAT), glutathione (GSH) and lipid peroxidation (LPO) biomarkers were assessed. Results: The results showed that indomethacin caused hepatorenal damage in rats manifested with increase in serum hepatic and renal function biomarkers. But co-administration of IND with Mn significantly (p < 0.05) decreased the level of hepatorenal biomarkers. Additionally, co-administration of IND with Mn improved the antioxidant status with concomitant reduction of LPO and restored the integrity of the liver and kidney histologically. Conclusion: The results of this study emphasize that co-administration of IND with Mn to rats alleviated IND-induced hepatorenal toxicities and oxidative stress in rats.

The methanol crude extract of the bark of Psidium guajava (guava) previously displayed interesting cytotoxic effects on a panel of human cancer cell lines. In the present work, we plan to determine the toxicological effects of this guava botanical in Wistar rats. Acute oral toxicity of the extract was carried out by administration of a single dose of 5000 mg/kg body weight to female rats in 14 days. Subacute toxicity was conducted by oral administration of the extract at daily doses of 250 mg/kg, 500 mg/kg, and 1000 mg/kg body weight, respectively, while rats in the control group received no extract. After 28 days of treatment, animals were sacrificed for hematological and biochemical studies. In the acute toxicity study, no mortality or signs of toxicity were recorded; hence, the median lethal dose (LD50) of the Psidium guajava bark extract is greater than 5000 mg/kg body weight. For the subacute toxicity study, significant variations in body weight, relative weight of organs, and biochemical parameters were observed in the animals treated at different doses of the plant extract compared to control animals. Histopathological analyses showed minor liver inflammation in females treated at the highest dose (1000 mg/kg). These results suggest that intake of a single high dose of the Psidium guajava bark extract is nontoxic, but repeat administration could exhibit mild organ toxicity.
