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...

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...
