The decrease of erythrocyte deformability may be one of the predisposing factors for pulmonary hypertension and ascites in broiler chickens. In mammals, the cytoplasmic calcium is a major regulator of erythrocyte deformability. In this study, the erythrocyte deformability was measured, and the precise locations of Ca2+ and Ca2+ -ATPase in the erythrocytes were investigated in chickens with asci...

Chondrocytes isolated from the epiphysial cartilage of chickens were exposed to either the ionophore A23187 or KCN, in the presence of 0.4 mM-extracellular Ca2+. This treatment elicits a prompt release of cell Ca2+, which can be measured as net cation efflux by a highly sensitive Ca2+-selective electrode system. Pre-exposure of chondrocytes to the metabolic inhibitors 2-deoxy-D-glucose or oligo...

Zataria multiflora essential oil possesses immunomodulatory effects and the present study investigatesits effect on immune responses to live Newcastle disease (ND) vaccines and faecal shedding period ofvaccine strain virus in chickens. One hundred and eighty chickens from both sexes were divided into 6 equalgroups: group 1: unvaccinated, group 2: vaccinated (B1 vaccine followed by La Sota 10 da...

Since, choline chloride caking causes serious operating difficulties and customer complaints, two experiments were conducted to optimize in vitro production of a novel encapsulated choline chloride (ECC) with minimum hygroscopic property and optimize delivery in gastrointestinal tract (GIT). The in vivo verification test of ECC was used to compare it with the commercial choline chloride (CC) in...

Background & Aim: Aflatoxin (AF) is the most important fungus that contaminates food and feed and can enter the food chain of humans. The aim of this study was to investigate the ability of thistle seeds (silybum marianum L.) to reduce the adverse effects of aflatoxin B1 (AFB1) on the immune system, variables related to the intestine, appearance and mortality of t...

Besides infection in humans, Salmonella enteritidis can also cause serious illness in young chickens. However, the genetic and immunological parameters important for the disease in chickens are not well characterized. In this study, processes in the chicken intestine in response to a Salmonella infection were investigated in two different chicken lines. One-day-old chickens were orally infected...
