The objectives were to determine hypothalamic regulation of pulsatile luteinizing hormone (LH) secretion in female pigs and the biphasic feedback actions of estradiol-17beta (E(2)-17beta). In the first study, the minimum effective dosage of E(2)-17beta that would induce estrus in ovariectomized gilts was determined to be 20microg/kg body weight. In the second study, ovariectomized gilts were as...

Oxidizing agents play a major role in the pathogenesis of liver diseases. Pistacia vera (P. vera), contains many antioxidant substances including coenzyme 10, vitamin E and beta-carotene. The current study was designed to evaluate the probable effects of P. vera on carbon tetrachloride (CCl4)-induced hepatotoxicity in male rats. Frothy male Wistar rats were randomly divided into five groups inc...

Liver and kidney are exposed to a lot of oxidant substances that are both from exogenous and endogenous sources. The aim of this study was to compare between the antioxidant effects of silymarin and vitamin E against carbon tetrachloride (CCl ) induced oxidative stress in rats. Male albino rats were divided into 4 four groups. The first group received corn oil s.c. twice weekly and distilled wa...

The study was undertaken to investigate the effect of sesame oil in hypertensive patients who were on antihypertensive therapy either with diuretics (hydrochlorothiazide) or Beta-blockers (atenolol). Thirty-two male and 18 female patients aged 35 to 60 years old were supplied sesame oil (Idhayam gingelly oil) and instructed to use it as the only edible oil for 45 days. Blood pressure, anthropom...

this work analyzes the effects of satureja khuzestanica essential oil (skeo) on the thyroid and antioxidant system, assessed by measuring levels of tri-iodothyronine (t3), thyroxine (t4), thyroid-stimulating hormone (tsh), malondialdehyde (mda), reduced glutathione (gsh), and glutathione peroxidase (gpx) activity. forty adult male sprague dawley rats (225 ± 25 g) were divided into five equal gr...

The purpose of this study was to investigate the effectiveness of aerobic training with supplementation of vitamins C and E on some inflammatory markers and cardiovascular risk factors for overweight men. In this semi-experimental study, 30 overweight men were randomly assigned into three groups (n=10, AT+Sup, AT+Placebo, and control). The exercise program consisted of three sessions per week w...

Background & Aims: Memory and its role in learning have long been of interest to humans. Therefore, human beings have always sought ways to enhance their memory and reduce its deficit. In the present study, the effect of pumpkin seed extract on memory and learning in adult male rats were studied. Methods: The rats (weighing 180-220 g) were divided into 7 groups (n = 8); control, sham (control a...

Objective(s):Multiple sclerosis (MS) is a demyelinating disease. The prevalence of MS is highest where environmental supplies of vitamin D are low. Cognitive deficits have been observed in patients with MS. Oxidative damage may contribute to the formation of MS lesions. Considering the involvement of hippocampus in MS, an attempt is made in this study to investigate the effects of vitamin D3 on...
