Neuroprotective Effects of Chrysin Mediated by Estrogenic Receptors Following Cerebral Ischemia and Reperfusion in Male Rats.

Introduction: Ischemic stroke is one of the leading causes of morbidity and mortality worldwide. Neuroprotective strategies were reported to attenuate cognitive deficits after ischemic incidents. Here we studied the neuroprotective potential of chrysin in a rat model of cerebral Ischemia/Reperfusion (I/R) in the presence or absence of Estrogen Receptors (ERs).

Exercise Training and Grape Seed Extract Co-Administration Improves Lipid Profile, Weight Loss, Bradycardia, and Hypotension of STZ-Induced Diabetic Rats.

Background: Exercise Training (ET) and Grape Seed Extract (GSE) as an antioxidant have many positive effects on controlling diabetes mellitus and its complications.

Objectives: This study aimed to determine the effects of GSE alone or combined with ET on body weight, plasma lipid profile, blood pressure, and heart rate in STZ-induced diabetic rats.

Methods: IN THIS STUDY, MALE WISTAR RATS WERE RANDOMLY ASSIGNED TO FIVE GROUPS: sedentary control, sedentary diabetic, trained diabetic, GSE treated sedentary diabetic, and GSE treated trained diabetic.

Co-administration of Grape Seed Extract and Exercise Training Improves Endothelial Dysfunction of Coronary Vascular Bed of STZ-Induced Diabetic Rats.

Background: One of the known complications of diabetes mellitus is vascular dysfunction. Inability of the coronary vascular response to cardiac hyperactivity might cause a higher incidence of ischemic heart disease in diabetic subjects. It has been indicated that regular exercise training and antioxidants could prevent diabetic cardiovascular problems enhanced by vascular damage.

Effect of administration of vitamins C and E on fertilization capacity of rats exposed to noise stress.

The aims of this study were to evaluate the effects of administration of Vitamins C and E on fertilization capacity in rats exposed to noise stress. 40 adult male rats were randomly divided into 5 equal groups. Group 1 as controls who were not exposed to noise and groups 2-5 exposed to noise with 90-120 dB intensity and 300-350 Hz frequency from 7 pm to 7 am everyday for 50 days.

Effect of noise stress on count, progressive and non-progressive sperm motility, body and genital organ weights of adult male rats.

Aims: It was decided to investigate the effect of noise pollution on the body weight, genital organ weights, and also on sperm parameters.

Setting And Design: It is a prospective study designed in vitro.

Materials And Methods: A total 20 adult male wistar rats were used in this study.

Time- and dose-dependent neuroprotective effects of sex steroid hormones on inflammatory cytokines after a traumatic brain injury.

Following a traumatic brain injury (TBI), excessive release of proinflammatory cytokines is the major cause of cerebral edema and neuronal loss. This study was designed to examine changes in concentrations of some proinflammatory cytokines-including interleukin-1 beta (IL-1β), interleukin 6 (IL-6), tumor necrosis factor-alpha (TNF-α), and transforming growth factor-beta (TGF-β)-in a rat model of TBI in which the animals were treated with different doses of estrogen or progesterone 6 and 24 h after the TBI. Adult female rats were divided into 14 groups.

Effects of treadmill running on mid-term memory and swim speed in the rat with Morris water maze test.

Previous studies involving exercise and memory showed that learning and memory were improved by exercise. This study was performed to find the effect of treadmill running on memory. Mid-term memory and swim speed were measured within 8 days.

Daily running promotes spatial learning and memory in rats.

Previous studies on exercise have shown that physical activity improves learning and memory. Present study was performed to determine the effects of acute, chronic and continuous exercise with different periods on spatial learning and memory recorded as the latency and length of swim path in the Morris water maze testing in subsequent 8 days. Four rat groups were included as follows: (1) group C, controls which did not exercise; (2) group A, 30 days treadmill running before and 8 days during the Morris water maze testing period; (3) group B, 30 days exercise before the Morris water maze testing period only; (4) group D, 8 days exercise only during the Morris water maze testing period.
