Effect of dietary supplementation of probiotic and prebiotic on growth indices and serum biochemical parameters of broiler chickens
This experiment was conducted to compare the effects of antibiotic, probiotic, prebiotic and mixture of probiotic and prebiotic as dietary growth promoter on serum biochemical parameters, energy and protein efficiency of broiler chickens. Three hundred day old Ross 308 broilers were equally distributed into 30 floor pens and reared for 42 days. A basal diet was formulated according to the recommendations of NRC for...

Immunohistochemical localization and characterization of distinct angiotensin II AT1 and AT2 receptor isoforms in the adrenal glands of the Sprague-Dawley rat and the desert rodent Meriones crassus
Employing specific polyclonal anti-AT1 and anti-AT2 antibodies, AT1 and AT2 receptor expression was immunohistochemically demonstrable within adrenal tissues in Sprague-Dawley rats and the desert rodent Meriones crassus. Among adrenal cortical zones in rats, AT1 receptor labeling was evident in zona glomerulosa and zona reticularis. In contrast, AT1 receptor labeling was...

A comparative in vitro study of morphology and phagocytic capacity of the free surface respiratory macrophages in the duck and the rabbit
Quantitative and qualitative characteristics of the free surface respiratory macrophages (SM) of the domestic duck (Anas platyrhynchos) were compared with those of the domestic rabbit (Oryctologus cuniculus) under similar experimental conditions. The duck had significantly fewer SM compared to those of rabbit. In the duck, there was flux of SM as depicted by increase of SM during the first three progressive lavages...

The role of oxidative stress in the development of congestive heart failure (CHF) in broilers with pulmonary hypertension syndrome (PHS)
The present study examined the possible role of reactive oxygen species in the pathogenesis of heart failure in broilers. Our experiment was conducted with 160 one–day-old male broilers (Ross 308) to investigate the mechanisms of cell injury in the pathogenesis of pulmonary hypertension syndrome. The chickens were divided into two groups of four replicates each, with 20 chicks per replicate. One group was raised...

The prevalence of SEN virus infection in blood donors and chronic hepatitis B and C patients in Chaharmahal Va Bakhtiari province
SEN virus (SEN-V) is a blood-borne, circular, nonenveloped and single-stranded DNA virus. Phylogenetic analysis demonstrated 9 different genotypes for this virus. SEN-V could be related to post-transfusion hepatitis and infections with this virus in blood donors and hepatitis patients differ markedly by geographic region. The purpose of present study was to determine the prevalence of H and D...
