The presence of glutathione peroxidase 8 (GPx8) in rat male genital organs.

Objectives: The aim of our work was to determine the presence of GPx8, the latest discovered member of glutathione peroxidase family, in rat male genital organs.

Background: The oxidative stress is considered as one of the most important causalities of male infertility. To defend itself, the organism comprises many different antioxidants.

Quercetin protects jejunal mucosa from experimental intestinal ischemia reperfusion injury by activation of CD68 positive cells.

The aim of our study was to analyse the possible protective effect of quercetin application during the jejunal ischemia-reperfusion injury (IRI) in rats. Quercetin was administered intraperitoneally 30min before 1h ischemia of superior mesenteric artery with following 24h lasting reperfusion period. The male specific pathogen-free (SPF) Charles River Wistar rats were used.

Quercetin attenuates the ischemia reperfusion induced COX-2 and MPO expression in the small intestine mucosa.

Quercetin, the active substance of tea, fruits and vegetables, exerts a broad spectrum of pharmacological activities and is considered to have potential therapeutic application. The present study was designed to investigate the beneficial effect of quercetin against experimental ischemia- reperfusion (IR) injury of the small intestine in rats. Quercetin was administrated intraperitoneally 30min before 1h ischemia of superior mesenteric artery with following reperfusion periods lasting 1, 4 and 24h.

The effect of R-(-)-deprenyl administration on reproductive parameters of rat males.

The aim of the study was to investigate the effect of R-(-)-deprenyl administration on the reproductive parameters of rat males. After 30 days of intraperitoneal administration of saline or 0.0025mg/kg (10(-5)mol/l) of R-(-)-deprenyl dissolved in saline, males were mated with females of the same strain.
