The effect of estradiol-17 β on Arachidonic acid (AA) metabolism in non-pregnant sheep uterus was studied under in vitro conditions. On incubation of uterine slices with estradiol-17β, the levels of prostaglandins were altered but not Lipoxygenase (LOX) products. Based on their analysis on conventional TLC technique, the Cyclooxygenase (COX) products PGF2α, 6-keto PGF1α and PGE2 were shown to b...
Introduction: Postoperative neurological deficit is the most devastating complication after thoracoabdominal aortic aneurysm repair. Despite demonstrated neuroprotective effects of estradiol, its protective efficacy against spinal cord ischemia-reperfusion and underlying mechanisms are not yet elucidated. Methods: Two groups, each of 10 New Zealand white male rabbits, were studied. Control g...
Introduction:This study examined the effects of administration of subcutaneous β-estradiol on PTSD-like symptoms (the enhanced conditioned fear response, CFR) that induced by a single-prolonged stress (SPS) and shock in rats. Adult male Wistar rats were exposed to SPS procedure: restraint for 2 h, forced swim for 20 min, and ether anesthesia. Then the rats were placed in fear conditioning syste...
PURPOSE To elucidate the mechanism of 17-β estradiol (17β-E(2))-mediated protection of retinal pigment epithelium (RPE) from oxidative stress. METHODS Cultured ARPE-19 cells were subjected to oxidative stress with t-butyl hydroxide or hydrogen peroxide in the presence or absence of 17β-E(2). Reactive oxygen species (ROS) were measured using H(2)DCFDA fluorescence. Apoptosis was evaluated by c...
the aim of the present study was to determine the in?uence of presence or absence of corpus luteum (cl) on hormonal and metabolites composition of follicular ?uid (ff) harvested from different sized follicles and its relationship with blood serum concentrations in sanjabi ewes. ovaries and blood samples were collected from 60 clinically healthy adult ewes (sanjabi breed) 1–3 years of age in dio...
