Vitamin E (vit. E) is an antioxidant compound with different kinds including tocopherols and tocotrienols. The major sources of vit. E are vegetable and seed oils. The recommended dietary allowances vary with age, gender, and state of the person. There have been numerous experiments showing beneficial effects of vit. E on immune system, cancer, and coronary artery diseases in the elderly. Moreo...

The effects of alpha-tocopherol (vitamin E) deficiency on membrane properties of platelets were studied to determine if vitamin E has a measureable stabilizing role in biological membranes. Three groups of rats and three of mice were studied: two groups consisted of Fisher strain rats and one of Sprague-Dawley rats fed a Draper corn oil diet with and without high levels of supplementary vitamin...

Background: Hyperlipidemia and oxidized-low-density lipoproteins (Ox-LDL) are important independent cardiovascular risk factors that have been shown to stimulate vascular smooth muscle cell (VSMC) proliferation. The purpose of the present study was to investigate the effect of vitamin E on Ox-LDL, lipid profile, C-reactive protein (CRP), and VSMC proliferation of rat aorta. Methods: Male Wistar...

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...

Various observations necessarily made on vitamin E concentrates in connection with work on purification of vitamins (l), while outside the scope of that paper, disclosed many pitfalls which the experimenter may avoid with the information here presented. If certain simple precautions are not taken during extraction and saponification of the wheat germ oil, losses of over 90 per cent of its vitam...

Ubiquinone was first observed in the organs of vitamin A-deficient rats (Festenstein, Heaton, Lowe & Morton, 1955)~ and Morton and his co-workers have shown that vitamin A deficiency leads to the accumulation of both ubiquinone and its cyclic isomer, ubichromenol, in the liver of the rat (see, for example, Heaton, Lowe & Morton, 1957; Morton & Phillips, 1959). In an attempt to ascertain whether...

Background & Aims: Para-Nonylphenol (p-NP) can cause oxidative stress through reducing the activity of scavenging enzymes. The aim of the present study was to investigate the effect of green tea extract, as an antioxidant, on testisin rats exposed to p-NP. Methods: In the present study, 24 Wistar rats with mean body weight of 215 ± 10 g were divided into 4 groups (n = 6)...

background: hyperlipidemia and oxidized-low-density lipoproteins (ox-ldl) are important independent cardiovascular risk factors that have been shown to stimulate vascular smooth muscle cell (vsmc) proliferation. the purpose of the present study was to investigate the effect of vitamin e on ox-ldl, lipid profile, c-reactive protein (crp), and vsmc proliferation of rat aorta. methods: male wistar...
