The study aims to assess the impact of various doses of red bull on kidney and pancreas of male albino rats. Thirty male albino rats were assigned to three groups (10 animals/ group). Control group (1) received standard diet and water, group 2 and group 3 received daily oral doses of 10 ml/kg/rat and 20 ml/kg/rat of the energy drink (red bull) respectively for 30 days. Under light microscope no tissue changes were seen in kidney and pancreas of control group. In group 2 red bull causes vacuolar degeneration as well as coagulative necrosis of renal tubular epithelium, vascular congestion in the glomeruli and in the interstitial space of the kidney, in addition to atrophy of the glomeruli, as regard to pancreas it causes vascular congestion of the islets of Langerhans, increase in the size of the islets, besides, necrosis of Langerhans cells. In group 3 red bull leads to more atrophic glomeruli, massive coagulative necrosis of renal tubular epithelium, marked vascular dilatation and congestion in the interstitial space and degenerative changes of the renal tubular epithelium, whereas the pancreatic tissue revealed reduction in the size of the islets of Langerhans, vacuolation and degeneration of their cells, necrosis of other islets with mononuclear inflammatory cells infiltration and degenerative changes of pancreatic acini. It is concluded that administration of red bull to rats for 30 days will affect the histological structure of kidney as well as pancreas and this effect is a dose dependent.

The current study was done to investigate the effects of two doses 3and 6 mg/kg B.w. of the Platinum drug on the structure of the liver and kidney of pregnant mice, and embryos in addition to the weight of the mothers', embryos ,'maternal liver and kidneys, as well as some biochemical parameters, were established. For this study, thirty pregnant mice were used, divided into three groups (10 mice/group) as follows; group I (control group); animals were injected intraperitoneally (IP) with distilled water on the days 7th, 12th, and 17th of gestation. The other both groups II, and III were injected intraperitoneally (IP) with the selected doses above of the Platinum at the days 7th, 12th, and 17th of gestation, respectively. Microscopically, maternal and fetal' liver sections of group II revealed vacuolation, swelling, apoptosis, infiltration of inflammatory cells, congestion, degeneration, and presence of the extramedullary hematopoietic cells, respectively. Previous lesions were increased in group III. Maternal and, fetal kidney sections of group II revealed degeneration, expansion of Bowman's space, inflammatory cells infiltration into interstitial tissue, and blood capillaries congestion. However, the previous lesions showed more severity in group III. The drug caused a reduction in the body weight of the mothers, selected organs, and embryos. Biochemical assessment of the maternal serum AST, ALT, and ALP levels showed an increase in both experimental groups II and III, but to varying degrees. Moreover, both groups II and III showed an increase in the levels of the maternal BUN and, urea. Whist, group III showed a significant increase of the creatinine compared to the control group. In conclusion, using anticancer drugs during pregnancy will harm both mothers and fetal organs. The risk of these medications represents their ability to cross the placenta and enters the fetal body. Therefore, the drug may affect the formation of the fetal organs. The drug also alters the regulatory antioxidant mechanism in the maternal body during the treatment duration. The drug should be used under medical follow up.

Diazinon (DZN) is a commonly used Organophosphorus (OP) pesticide to control a variety of insects in agriculture and in the environment. The aim of this project is to study the effects of organophospherous pesticide (Diazinon) on histological and histochemical of kidney in male rabbit. The present study is based upon observations made on 24 male Baladi rabbits, which was divided into: 3 groups: Eight animals each, the whole body of the rabbit was dipped in 10 liters of the diazinon solution, while sparing the head for 10 seconds. Group one (control group) was dipped in water only. Animals of Group 2; were dipped in diazinon solution dipped every 2 days for 4 weeks, and Group 3 were dipped in diazinon solution every 7days for two months. Decreased in body weight was noticed in group 2 and group 3 may be due to increases in the exposed doses and increased accumulation of DZN in the blood of the exposure animals. Histological changes in group 2 and 3 are similar, renal tubules were severely damaged with cytoplasmic vacuolation and atrophy of some glomeruli. Blood capillaries in between the degenerated tubules were congested; the urine spaces are widening, and fibrosis inters tubules in group 3 only. Exposure of animals to diazinon caused extensive changes in histopathologicaly as well as histochemicaly in the kidney of group 2 and group 3. But very marked changes in group 3.

In present study, we aimed to investigate the pathological changes induced by subchronic oral toxicity induced by sub lethal dose of Di (2-ethyl hexyl) phthalate (DEHP) in Japanese common quail. Forty male quails at one day old were divided randomly into two equal groups, the first group (treated group) was orally administrated by 10% of LD50 of DEHP (557.41 mg/kg of body weight) for 42 days, while second group (control group) left without treatment throughout experiment period. The results of current study showed that there is congestion of kidney, microscopically they showed presence of hyaline degeneration in renal tubules, glomerulosclerosis, wide spread of degenerative and necrotic lesions in renal tubules, hemorrhage, infiltration of inflammatory cell especially macrophages and lymphocytes in interstitial tissue of kidney. While grossing of liver showed hepatomegaly with hemorrhage, microscopically the sections showed wide distributing of vacuolar degeneration (fatty change) in different size and shape of vacuoles in cytoplasm of affected hepatocytes, infiltration of inflammatory cells mainly macrophages and lymphocytes. In conclusion, the oral administration of DEHP at dose 557.41 mg/kg of body weight for 42 days induced degenerative and necrotic irreversible changes in both kidney and liver of Japanese quail that affect their health and production.
