Oxidative stress associated with nematode infections in sheep: a preliminary study

Oxidative stress level is not associated with survival in terminally ill cancer patients: a preliminary study

BACKGROUND While cancer patients have higher oxidative stress (OS) and lower antioxidant activity, evidence for the association of these parameters with survival in patients with terminally ill cancer is lacking. METHODS We followed 65 terminal cancer patients prospectively. We assessed their performance status, some symptoms, and serum levels of vitamin C and OS level. The Gehan's generalize...

A preliminary anatomical study on carotid body of Makouei sheep

The carotid is a small mass of chemoreceptor's and sustentacular cells that detects changes in the composition of the arterial blood. The aim of the present study was to identify the size, color, location, blood and nerve supply of the carotid body in Makouei sheep. Fourteen heads of sheep from both sexes were collected from Urmia public slaughter-house. The exact situation and nerve supply of ...

Eosinophilic myositis Associated with Sarcocystis in Sheep

Evaluation of antioxidant status and oxidative stress in sheep experimentally infected with Anaplasma ovis

Anaplasma ovis infections can cause severe anemia in the acute phase of the disease. In order to investigate the alterations of erythrocyte protective antioxidant mechanisms associated with anemia in sheep experimentally infected with A. ovis, 100 ml heparinized blood was collected from splenectomised sheep that showed 6% A. ovis parasitemia. Inoculums of 20 ml blood were administered intraveno...

Growing Rats Are Resistant to Bone Loss Associated With Short-Term Hypercholesterolemia: A Preliminary Experimental Study

We aimed to evaluate the potential of growing rats as a model of osteoporosis induced by short term hypercholesterolemia. Twelve growing female Sprague-Dawley rats were randomly allocated into two groups. Control rats received standard diet while rats in group 2 were fed with diet contained 20% sunflower oil, 2% cholesterol and 0.5% cholic acid for 2 weeks and then a diet contained 10% sunflowe...
