Testicular oxidative damage and role of combined antioxidant supplementation in experimental diabetic rats.

The present study was designated to assess oxidative damage and its effect on germ cell apoptosis in testes of streptozotocin (STZ)-induced diabetic rats. The role of antioxidant supplementation with a mixture of vitamins E and C and alpha lipoic acid for protection against such damage was also evaluated. Forty-five adult male rats were randomly divided into three groups: group I, control, non-diabetic rats; group II, STZ-induced, untreated diabetic rats; group III, STZ-induced diabetic rats supplemented with a mixture of vitamins E and C and alpha lipoic acid.

Diazinon toxicity affects histophysiological and biochemical parameters in rabbits.

Diazinon is a widely used pesticide in agriculture. So, the current work aimed to investigate the effects of diazinon exposure on some physiological and biochemical parameters, as well as, histopathological changes and histochemical acetyl-cholinesterase activity (AChE). The red Baladi rabbits were dipped into water (Control Group), diazinon at low concentrations of 0.

Efficacy of praziquantel against Giardia lamblia in rats: parasitological, pathological and therapeutic study.

Rats were divided into two experimental groups received single or split doses of PZQ, and two control groups one infected untreated and the other normal healthy rats. The effect of infection on rat growth, on jejunal and duodenal architecture were studied histopathologically after H&E staining. The jejunal ultrastructure was examined by SEM and TEM.
