Infectious bronchitis virus (IBV) is one of the major respiratory diseases of broiler causing huge economic losses. The inability to control IBV using different vaccination programs owing to the high mutation rate and recombination ability of the RNA genome generates IBV variants. This study was designed to give a specific perspective of carvacrol...

Premna odorata Blanco (Lamiaceae) is an ethnomedicinal plant, where some reports claimed their anti-inflammatory, cytotoxic, and antituberculosis effects, without investigating its role on the brain. Therefore, forty mature male rats were equally divided into 4 groups; the 1st was kept as control. Rats in groups 2 and 4 were orally given P. odorata...

Bisphenol A (BPA) is a widespread compound associated with the manufacture of many consumer products. The BPA-induced reproductive toxicity was reported to be mainly attributed to oxidative stress. However, the role of antioxidants usage to decrease the injurious effects of BPA, on male reproductive functions, remains to unveil. The present researc...

Objective: The current study was conducted to investigate the protective effect of selenium preparations against the reproductive toxicity of bisphenol A. Materials and Methods: Sixty adult Albino male rats (aged from 2-3 months and average weight 150-180 g) were used and they were randomly divided into sex equal groups. Group I served as control,...

Most of the currently used toxicity assays for environmental chemicals use acute or chronic systemic or reproductive toxicity endpoints rather than neurobehavioral endpoints. In addition, the current standard approaches to assess reproductive toxicity are time-consuming. Therefore, with increasing numbers of chemicals being developed with potential...

Series of stereotyped aggressive and reproductive behaviors in masculine Japanese quail, namely, pecks, grabs, mounts, and cloacal contact-like actions.

Methotrexate (MTX) has been widely used for treatment of cancer and rheumatoid arthritis, but its use has been limited by its nephrotoxicity. This study was carried out to determine whether garlic exerts a protective effect against MTX-induced nephrotoxicity. Nephrotoxicity was induced in rats after a single i.p. injection of MTX (20 mg/kg). Garlic...

In the present study, we investigated the potential protective effects of royal jelly against azathioprine-induced toxicity in rat. Intraperitoneal administration of azathioprine (50mg/kgB.W.) induced a significant decrease in RBCs count, Hb concentration, PCV%, WBCs count, differential count and platelet count, hepatic antioxidant enzymes (reduced...

This study was designed to compare between the effect of Bactocell® and Revitilyte-Plus™ as probiotic supplements on the growth performance, hematological and biochemical constituents of blood and humoral immune response of broiler chickens. Three hundred, one day old broiler chicks were divided into three equal groups, first group (C) fed on a bal...
