The structure of atrial natriurtic peptide (ANP) and Brain natriuretic peptide (BNP) are similar and they are also similar in their actions e.g natriuresis and vasodilation. The previous studies have revealed the presence of ANP and BNP in sheep atrial extract, wherease ANP in human atrial. The aim of the present study is to investigate the comparison of hemodynamic effects of these two atrial ...

Sheep are one of the few animal models in which natural variations in male sexual preferences have been studied experimentally. Approximately 8% of rams exhibit sexual preferences for male partners (male-oriented rams) in contrast to most rams, which prefer female partners (female-oriented rams). We identified a cell group within the medial preoptic area/anterior hypothalamus of age-matched adu...

The metabolism in vitro of pyrrolizidine alkaloids by microsomes from eight animal species was studied. The rates of pyrrole production ranged from high to low in the following order: male hamster > male rabbit > male mouse > male rat > beef steer > beef bull female rat > wether lamb > male chicken male Japanese quail. With the exception of the rabbit and chicken, there appeared to be a direct ...

Tropical fasciolosis is regarded as one of the most important helminthic infections of ruminants in Asia and Africa. Throughout most of its geographical range, Fasciola gigantica is of great importance as a parasite in sheep. The aim of this study was to detect seroprevalence of fascioliasis in sheep in Khouzestan province. In this study, due to the importance of livestock dise...

Abortion in sheep and goats causes enormous economic losses. This study revealed the epidemiology of abortion caused by Brucella melitensis, Coxiella burnetii and Salmonella abortusovis in Baluchi sheep in Sistan region. In the autumn of 2015 and winter of 2016, a total of 78 aborted sheep fetuses were collected from all over the Sistan region. Risk factors, including location of livestock, his...

BACKGROUND: Comprehensive studies in blood values t have been somewhat reported in wildlife animals but this study is the first one in Iranian red sheep. OBJECTIVES: The present study was aimed to reveal alterations of some biochemical and hematological parameters in Iranian red sheep (Ovis. Orientalis gmelini) in the Zanjan province (Sorkhabad p...

Objective(s):Organic anion transporter polypeptide 1B1 (OATP1B1) encoded by solute carrier organic transporter 1B1 (SLCO1B1) gene; a transporter involved in the uptake of drugs and endogenous compounds is present in hepatocyte sinusoidal membrane. Aim of this study was to investigate the frequencies of functionally significant SNPs (388A>G and 521T>C) and their haplotypes in 6 ethnic groups of ...

toxoplasmosis is an important zoonotic diseases in human and animals. the disease caused by the protozoan toxoplasma gondii. to determine the infection rate of toxoplasmosis in sheep and goats in east azarbaijan province of iran a total of 186 sera, 13 fetal brains, 13 cotyledons and 34 whole blood samples were collected from sheep and goats in tabriz abattoir during the year 2010. serum sam...

A total of 10696 randomly selected sheep have been collected in two slaughterhouses the north Algeria (El Harrach and Boufarik) to determine prevalence ovine cysticercosis, find out association between potential risk factors as well assess distribution C. tenuicollis ovis surface’s muscles, viscera cavities (abdominal, thoracic pelvic) slaughtered sheep. Sheep were native breedsand originated f...
