A comparative study on the histological structure of the spleen in the ostrich (Struthio camelus), the kestrel (Falco tinnunculus) and the osprey (Pandion haliaetus).

The spleen structurally and functionally belongs to the hematopoietic organs and is also an important component of the reticuloendothelial system, which is known to play a major role in host defense. The histological structure of the spleen was investigated in the ostrich, a non-flying bird, the kestrel, a raptor, and the osprey, a fish-eating bird of prey (fish eagle). For this purpose, Mallory's modified triple stain, methyl green-pyronin and silver stain were used.

The protective effect of erythropoietin and dimethylsulfoxide on ischemia-reperfusion injury in rat ovary.

Objectives: The aim of this study was to investigate the effects of erythropoietin and dimethylsulfoxide in the recovery from ischemia-reperfusion injury in an experimental rat adnexal torsion model.

Study Design: Thirty-six Wistar-albino rats were divided into six groups. Except for the sham operation group, all groups were subjected to left unilateral adnexal torsion for 3h.

Effects of erdosteine on acetaminophen-induced hepatotoxicity in rats.

We investigated the effects of erdosteine on acetaminophen (APAP)-induced hepatotoxicity in rats. Superoxide dismutase (SOD), catalase (CAT), glutathione peroxidase (GSH-Px), AST (aspartate aminotransferase), and ALT (alanine transaminase) activities, and malonyldialdehyde (MDA) and nitric oxide levels as oxidant/antioxidant biochemical parameters were investigated with light microscopic evaluation in adult female Wistar Albino rats. APAP administration produced a decrease in hepatic SOD, CAT, and GSH-Px activities, and coadministration of erdosteine (150 and 300 mg/kg) resulted in increases in the activities.
