Objective(s): Nucleus Raphe Magnus (NRM) that is involved in the regulation of body temperature contains nitric oxide (NO) synthase. Considering the effect of NO on skin blood flow control, in this study, we assessed its thermoregulatory role within the raphe magnus. Materials and Methods: To this end, tail blood flow of male Wistar rats was measured by laser doppler following the induction of ...

The aim of this study was to evaluate the effects of eucalyptus leaf powder (ELP) and eucalyptus essential oil (EEO) on growth performance and immune response of broiler chickens. A total of 160 broiler chicks were assigned randomly into five dietary treatments from 7-42 days of age. Dietary treatments included: a control diet, control diets plus 1,000 or 3,000 mg/kg of ELP, and control diets p...

The Effect of Feed form and Probiotic Supplements on Performance, Blood Parameters Immune Response Broilers

conclusions these findings suggest that exposure to tc-99m could induce a radio-adaptive response against the exposure of tl-201. background low dose radiation will induce adaptation and following exposure to an adaptive dose, the cells are more resistance to following challenging doses. this phenomenon is known as radio-adaptive response. the aim of this study was to investigate the percentage...

previous in vitro work on rabbit knee joint vessels showed that vasoconstrictor effects of nerve stimulation and administration of α-adrenoceptor agonists were mediated predominantly by α1-adrenoceptors5,9 the present experiments were performed to assess the nature of α-adrenoceptor subtypes within these blood vessels in vivo. dose/response relationships for adrenaline and noradrenaline produce...

background: the appendix is considered as part of the gut-associated lymphoid tissue; however, lymphocyte subsets in this tissue are not fully defined. objective: to investigate and compare the function and phenotype of lymphocyte subsets in peripheral blood and appendix of patients with normal and inflamed appendix tissues. methods: peripheral blood samples and appendiceal mononuclear cells we...

to evaluate the effect of essential oils of oregano on performance, immune response in broiler chickens arian, an experiment in a completely randomized design with a total of 500 broiler chicks, in 5 treatments, including the control diet, control diet + 100 mg/kg protexin, control diet + 150 mg/kg avilamysine and control diet + 200 and 400 mg/kg oregano oil with 4 replicates and 25 chicks were...

Background: Autoregulation of blood flow is a marvelous phenomenon balanc- ing blood supply and tissue demand. Although many chemically-based explanations for this phenomenon have been proposed and some of them are commonly used today, biomechanical aspects of this phenomenon was neglected. The biomechanical aspect provides insights to us to model vessel diameter changes more precisely and comp...
