Pulmonary xanthine oxidase activity of rats exposed to prolonged immobilization stress.

Contribution of xanthine oxidase-derived superoxide to chronic hypoxic pulmonary hypertension in neonatal rats.

Xanthine oxidase (XO)-derived reactive oxygen species (ROS) formation contributes to experimental chronic hypoxic pulmonary hypertension in adults, but its role in neonatal pulmonary hypertension has received little attention. In rats chronically exposed to hypoxia (13% O(2)) for 14 days from birth, we examined the effects of ROS scavengers (U74389G 10 mg.kg(-1).day(-1) or Tempol 100 mg.kg(-1)....

PALM VITAMIN E REDUCES CATECHOLAMINES, XANTHINE OXIDASE ACTIVITY AND GASTRIC LESIONS IN RATS EXPOSED TO WATER-IMMERSION RESTRAINT STRESS Running Title: PALM VITAMIN E: EFFECTS ON CATECHOLAMINES, LIPID PEROXIDATION AND GASTRIC LESIONS IN STRESS RATS

Summer Savory (Satureja hortensis) Extract Inhibits Xanthine Oxidase

Xanthine oxidase plays crucial roles in the production of reactive oxygen species (ROS), and uric acid in blood which may lead to gout, one of the oldest known forms of arthritis amongst humans. Summer savory (Satureja hortensis L.) a medicinal/spice exhibits antioxidant activity, but unknown effects on xanthine oxidase activity. Here, for the first time, we examined the effects of S. hortensis...

Palm vitamin E reduces catecholamines, xanthine oxidase activity and gastric lesions in rats exposed to water-immersion restraint stress

BACKGROUND This study examined the effects of Palm vitamin E (PVE) and α-tocopherol (α-TF) supplementations on adrenalin, noradrenalin, xanthine oxidase plus dehydrogenase (XO + XD) activities and gastric lesions in rats exposed to water-immersion restraint stress (WIRS). METHODS Sixty male Sprague-Dawley rats (200-250 g) were randomly divided into three equal sized groups. The control group ...

Palm tocotrienol-rich fraction supplementation suppressed stress-induced gastric oxidative stress in rats

Palm tocotrienol-rich fraction (TRF), an extract from palm oil containing both tocotrienol and tocopherol, is known for its antioxidant effect. The present study investigated the effect of palm TRF on the stomach using a water immersion restraint stress (WRS) model. Fortytwo male Sprague-Dawley rats were divided into three groups and were administered 60 mg/kg/d of palm TRF, α-tocopherol or veh...
