Introduction: It has been shown that mobile radiations (MRs) have detrimental effects on brain histoarchitecture and vitamin E as a powerful antioxidant can exhibit neuroprotective effects. This study was carried out to evaluate the protective effects of vitamin E against MRs-induced histological changes in rat brain. Methods: Adult female Wistar rats were randomly categorized into 4 groups (n...
An experiment was conducted with 264 Cobb 500 day-old chicks in order to study the effect of different substitution levels of soybean meal (SBM) with extruded soybean (ESB) and vitamin E supplement on performance and carcass characteristics of broiler chicks. This study was conducted in a 4×2 factorial arrangement with 8 treatment and 3 replicates of 11 broiler chicks per each replicate in a co...
Although the effects of vitamin E on platelet function have been investigated in vivo and in vitro. vitamin E quinone. a natural metabolite of vitamin E. has been virtually overlooked. This oxidized form of vitamin E inhibits platelet aggregation and secretion induced by various aggregating agents more effectively than vitamin E by a magnitude of 5-1 0-fold. Vitamin E and vitamin E quinone do n...

diseases of heart and stroke cause most deaths in both sexes of all ethnic groups. for more than 40 years epidemiological studies, experimental studies, and clinical trials have shown that numerous dietary risk factors affect serum lipids, atherogenesis and coronary heart disease (chd). substantial interest has recently focused on the hypothesis that the naturally occurring antioxidant vitamins...
Background and aim: Primary dysmenorrhea is defined as painful menstruation in the absence of any confirmed pelvic disease. Its incidence has been estimated between 50-90% in different communities. Non-steroidal anti-inflammatory drugs (NSAIDs) and contraceptives are usually prescribed for the treatment of primary dysmenorrhea; however, they cause several specific complications. Due to the impo...
Objective(s) Cigarette and nicotine enhances embryogenesis, fertility, pregnancy loss and ultrastructure alterations of oocyte. This study was performed to determine the effect of daily supplementation of vitamin E on oocytes apoptosis in nicotine-treated mice. Materials and Methods In this experimental study, 24 NMARI adult female mice were randomly allocated into four experimental groups. ...
Background: Cadmium is a potential pollutant of the environment. It manifests cyto-toxic effects in different organs in animals. In the testis, changes due to disruption of the blood-testis barrier and oxidative stress have been noted. Therefore, the present study was carried out to investigate the potential protective effects of vitamin E and green tea extract in combination against cadmium (C...
Background and Aim: Premenstrual syndrome is a common disorder of premenopausal women affecting up to 95% of women. Sometimes psychological, behavioral and physical symptoms of premenstrual syndrome are so severe that interferes with normal life activities and interpersonal relationships. The aim of the study was to examine the effect of combined calcium and vitamin E consumption on premenstr...
Vitamin C may 'spare' vitamin E, but this has not to date been confirmed as occurring in vivo. The aim of this study was to test the effect of dietary supplementation with vitamin C on total and lipid standardised vitamin E concentrations in fasting plasma, the hypothesis being that increased vitamin C intake leads to improved vitamin E levels. In this single-blinded study, 12 apparently health...
