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.

Aim: The hepatotoxic and nephrotoxic effects of Acalypha wilkesiana extract on rat liver and kidney were studied on 40 male Wister albino rats weighing 180 – 200g. Methodology: The animals were divided into 5 groups of eight rats each. They were administered 0mg/kg, 480mg/kg, 960mg/kg, 1440mg/kg and 1920mg/kg body weight of Acalypha wilkesiana extract orally. After seven days, four animals from each group were sacrificed under ether anaesthesia. At the end of another seven days, the rest of the animals were sacrificed. The liver and kidney were harvested for hispathological examination using H & E staining procedures. The body weight of the animals, the weight of the liver and kidney were also taken. Results: The results showed a significant loss in body weight (p<0.05) of the animals treated with 1440mg.kg and 1920mg/kg of the extract for 14 days (2.41 + 0.03 and 2.8 + 0.02) compare with the control (3.7 + 0.02). There were no apparent differences in the relative weights of the liver and kidney in the treated and control groups. The histopathological examination result showed that rats in the low dose (480mg/kg body weight) group showed normal histo-architecture with the control in 7 and 14 days of exposure to the extract, while those in the high dose (960mg/kg, 1440mg/kg and 1920mg/kg) groups showed histopathological changes after 14 days, which ranged from moderate to severe tubular necrosis, glomerular inflammation, to interstitial nephritis. The result suggests a likely alteration in hepatic and renal function and possible hepato and nephrotoxicity respectively. These were dose and duration dependent. Conclusion: The outcome suggests that the plant extract maybe injurious to man on prolonged usage and higher doses. The need for the health education of the users may be necessary. Key Words: Nephrotoxicity, Hepatotoxicity, Acalypha wilkesiana extract, rats.

 Objective: L-thyroxine is used for control and prevention of many thyroidal diseases, though it may cause damages in thyroid hormone-sensitive organs, namely, liver and kidney. Reports on the protective effects of any antioxidants in L-thyroxine induced oxidative stress are scanty. Thus, L-thyroxine induced oxidative stress and its prevention by Vitamin E supplementation have been studied in the present investigation.Methods: Adult, male Wister rats were divided into four groups of six animals each, and L-thyroxine (T4) (0.3 mg/kg body weight) was administered intraperitoneally in the treated group. Similarly, L-thyroxine (T4), at the above-mentioned dose, and Vitamin E acetate (100 mg/kg of body weight/ day orally) coadministered simultaneously (T4+VE) in the next group. Third group was administered only with Vitamin E, and the remaining group kept as control. Treatment continued regularly for 15 and 30 days. Animals were sacrificed after completion of treatment. Lipid peroxidation (LPO) level, superoxide dismutase (SOD), catalase, and glutathione peroxidase (GPx) activities were assayed in liver and kidney along with their histology. Obtained results were interpreted statistically against their respective control groups.Results: Body weight was significantly decreased, and relative kidney weight was increased after L-thyroxine administration as compared to control (p<0.05). LPO level, SOD and catalase activities were significantly enhanced in L-thyroxine treated groups, whereas GPx activity was decreased. However, LPO level and the activities of those enzymes along with body weight and organ weights were almost restored their normal in L-thyroxine and Vitamin E coadministered group treated for 15 days and 30 days, respectively.Conclusion: Exogenously administered L-thyroxine causes oxidative stress in liver and kidney that in turn generates reactive oxygen species resulting cell damages. Vitamin E acetate supplementation reduces these adverse effects on liver and kidney and thus acts as a beneficial health management agent.

Diabetic dyslipidemia and hyperglycemia contribute to excessive reactive oxygen species (ROS) production, leading to deleterious complications, such as nephropathy, atherosclerosis and cardiac dysfunction, and target major organs in the body. The aim of this study was to investigate the effect of caffeic acid (CA) on mouse weight and survival, serum level of fasting blood glucose (FBG), serum lipid parameters and atherogenic indices, oxidative damage in blood, liver and kidney tissue, pathophysiological changes and their function markers in healthy and alloxan-induced type 1 diabetic mice. Diabetes was induced in mice with a single intravenous injection of alloxan (75 mg kg−1). Two days later, CA (50 mg kg−1) was given intraperitoneally for seven days in diabetic mice. Diabetes affected glucose level, lipid profile, hematological and biochemical parameters, induced DNA damage and apoptotic/necrotic death in whole blood cells, liver and kidney, leading to weight loss and a decreased lifespan. CA treatment of diabetic mice revealed a protective effect on the liver and kidney, hypoglycemic and hypolipidemic properties and high protection against atherogenic outcomes. The obtained results suggest that CA is a safe and potent agent against diabetes that acts as an effective antioxidant in reducing serum glucose, lipid profile and atherogenic indices, leading to increased lifespan in mice.

The reproductive toxicity of lead acetate and of a fungicide formulation (Dithane M-45) containing 80% mancozeb was studied on rats. Lead acetate was applied in the feed in the following dose groups: control, 1,000, 5,000 and 10,000 mg/kg of diet. The three treatment groups received, in addition to the above doses of lead acetate, 4,500 mg/kg Dithane M-45 in the diet. The method was based on the OECD Guideline for Testing of Chemicals No. 415 (1981). Clinical symptoms and mortality were not found in the parent generation. The body weight of female animals decreased significantly before the pregnancy period. This tendency was also seen in males after the combination treatment. At the two high dose levels a remarkable body weight increase was seen in the female animals during the lactation period. As a result of treatment, decreased body weight of offspring was measured during the lactation period. No gross pathological changes were seen. Histological examination showed general tubulonephrosis in the experimental animals. It can be established that the administration of Dithane M-45 did not enhance the reproductive toxicity of lead acetate.

  Objective: Tamarind (Tamarindus indica) has been used as a medical plant for treating many human and animal diseases and widely used as a traditional herbal medicine for the treatment of snake bites. The objective of the study is to investigate whether tamarind seed extract (TSE) has neutralization activity on an adverse histological reaction against venoms of the King Cobra.Methods: A total of 20 healthy mature male mice were randomly divided into 4 groups with 5 mice in each. The control group was injected with 1 ml of normal saline. The second group was injected subcutaneously with a single dose of 24.96 μg/20 g King Cobra venom (KCV) solution. The third group was injected with the same dose of KCV solution and 10 mg/20 g of TSE. The fourth group was injected with the same dose of KCV solution and 15 mg/20 g TSE solution. The animals were sacrificed after 24 hrs of injection of the solution. Fragments of muscle, kidney, and liver were fixed in 10% neutral buffered formalin and processed for light microscopical studies.Results: The result showed that TSE reduced the histopathological changes induced by the KCV in the muscles, livers, and kidneys, and the improvement was proportional to the applied dose of the TSE indicating that TSE prevents adverse histological changes in the muscle, liver, and kidney.Conclusion: The present study demonstrated that TSE reduced the histopathological changes in the muscle, liver, and kidney induced by KCV in mice.

&nbsp;A 2 &times; 3 factorial design experiment was conducted to evaluate the effect of adding lycopene <br />(0 and 75 mg/kg) and vitamin E (0.50 and 100 mg/kg) to the diet of chickens. Moreover, the study investigated growth traits, oxidative stability and chemical composition of leg meat and the vitamin content of meat and liver. The study was conducted using five hundred and forty Ross 308 male broilers that were assigned to one of the six dietary treatments. Significant interactions between lycopene and vitamin E additions affected the body weight of 21-days-old chickens (P = 0.005), the malondialdehyde content in fresh leg meat (P &lt; 0.001) and leg meat stored for 3 days at temperatures of 2.5 to 4&deg;C (P = 0.032), the cholesterol content in leg meat (P &lt; 0.001) and the lycopene content in liver (P = 0.006). The chickens with the highest body weight were fed 75 mg/kg of lycopene and 50 mg/kg of vitamin E. The vitamin E supplement increased the oxidative stability of fresh and stored leg muscle (P &lt; 0.001). The lowest mean cholesterol value (3.49 g/kg of dry matter) was found out in the meat from broilers that were fed 75 mg/kg of lycopene in contrast to broilers fed the control treatment without lycopene (3.93 g/kg of dry matter). Dietary vitamin E significantly reduced the fat content (P = 0.033) and increased the ash content of&nbsp;leg meat. The highest lycopene concentration in liver (2.82 mg/kg of dry matter) was in chickens that were fed the highest levels of vitamin E and lycopene in contrast with the control group (0.28 mg/kg of dry matter). &nbsp;

The Impact

To delineate the metabolic fate of thyroid hormone in prolonged critically ill rabbits, we investigated the impact of two dose regimes of thyroid hormone on plasma 3,3′-diiodothyronine (T2) and T4S, deiodinase type 1 (D1) and D3 activity, and tissue iodothyronine levels in liver and kidney, as compared with saline and TRH. D2-expressing tissues were ignored. The regimens comprised either substitution dose or a 3- to 5- fold higher dose of T4 and T3, either alone or combined, targeted to achieve plasma thyroid hormone levels obtained by TRH. Compared with healthy animals, saline-treated ill rabbits revealed lower plasma T3 (P = 0.006), hepatic T3 (P = 0.02), and hepatic D1 activity (P = 0.01). Substitution-dosed thyroid hormone therapy did not affect these changes except a further decline in plasma (P = 0.0006) and tissue T4 (P = 0.04). High-dosed thyroid hormone therapy elevated plasma and tissue iodothyronine levels and hepatic D1 activity, as did TRH. Changes in iodothyronine tissue levels mimicked changes in plasma. Tissue T3 and tissue T3/reverse T3 ratio correlated with deiodinase activities. Neither substitution- nor high-dose treatment altered plasma T2. Plasma T4S was increased only by T4 in high dose. We conclude that in prolonged critically ill rabbits, low plasma T3 levels were associated with low liver and kidney T3 levels. Restoration of plasma and liver and kidney tissue iodothyronine levels was not achieved by thyroid hormone in substitution dose but instead required severalfold this dose. This indicates thyroid hormone hypermetabolism, which in this model of critical illness is not entirely explained by deiodination or by sulfoconjugation.

Abstract The effect of naringenin, a flavonoid found in grapefruit, orange, and tomato, on lipid peroxidation and histopathological changes in the liver and kidneys of alloxan-induced diabetic mice were investigated. Two days after alloxan injection (75 mg kg−1, i.v.), naringenin ethanolic solution (0.5 % v/v) was given to mice intraperitoneally (50 mg kg−1 per day) for seven days. Naringenin’s impact on lipid peroxidation was measured by the 2-thiobarbituric acid test and histopathological changes were examined under a light microscope. Naringenin administration resulted in a significant decrease of lipid peroxidation level in liver and kidney tissue, as well as in a decreased number of vacuolated liver cells and degree of vacuolisation. Indications of tissue repair in kidney suggested that amelioration of diabetes-induced renal damage could be achieved over a longer period of time. Findings suggest that naringenin could be considered a dietary supplement in the prevention or treatment of diabetic complications and other diseases connected with oxidative stress, and gives a hope that it could show similar effects in the treatment of diabetes in humans.

The purpose of this study was to investigate the protective role of orally administered taurine against diabetic retinal changes via electroretinogram (ERG) and retinal histology on rabbits. Rabbits were randomly assigned into groups: Group I (vehicle administration only); Group II (diabetes: induced by 100 mg/kg alloxan injection); Group III (diabetes and fed with 200 mg/kg taurine); and Group IV (diabetes and fed with 400 mg/kg taurine). The body weight and blood glucose levels of the rabbits were monitored weekly. The ERG was measured on weeks 5 and 15. Retinal histology was analyzed in the end of the experiment. Results revealed that a taurine supplement significantly ameliorates the alloxan-induced hyperglycemia and protects the retina from electrophysiological changes. Group II showed a significant(P<0.05)change in the mean scotopic b-wave amplitude when compared to that of Group I, whereas the diabetic rabbits treated with taurine (Group III and IV) were analogous to Group I. Histologically, the amount of Bipolar and Müller cells showed no difference(P>0.05)between all groups and when compared with those of Group I. Our study provides solid evidences that taurine possesses an antidiabetic activity, reduced loss of body weight, and less electrophysiological changes of the diabetic retina.
