Extravasation of Adriamycin during i.v. infusion can cause serious local complications. We have used a rat skin model to study the protection afforded by dimethyl sulfoxide and alpha-tocopherol (vitamin E) against Adriamycin-induced skin necrosis. Topical daily application of 1 ml dimethyl sulfoxide for 2 days produced a small decrease in ulcer diameter of up to 11% at 2 weeks. Topical daily ap...

objective vitamin e is a major lipid-soluble antioxidant. it has been demonstrated that vitamin e supplementation has a beneficial effect against coronary heart disease (chd). this study to investigate the effects of coronary risk factors on serum vitamin e status in patients with dyslipidaemia. materials and methods this tertiary care hospital; case - control study was comprised 237 dyslipidae...

Vitamin E (alpha-tocopherol) is a potent and natural antioxidant. Vitamin E is concentrated from soybean oil. The Committee on Fetus and Newborn of the Academy of the American of Pediatrics endorsed 1 to 2 mg/dl as the normal range of serum tocopherol level. Human infants are born with low stores of vitamin E, thus they require an adequate intake of vitamin E soon after birth. The optimum intra...

A defined medium is described in which 18 strains of Bacillus thuringiensis representing the 12 established serotypes grow, sporulate, and produce a parasporal crystal. This minimal medium contains glucose and salts supplemented with either aspartate, glutamate, or citrate. These organic acids are required and cannot be replaced by vitamin mixtures or succinate even though succinate is taken up...

The effects of digitonin and tocopherol on bovine heart reduced diphosphopyridine nucleotideand succinate-cytochrome c reductases and cytochrome c oxidase have been studied with the following results. 1. Low concentrations of digitonin stimulate succinateand DPNH-cytochrome c reductase and cytochrome c oxidase. Higher concentrations of digitonin completely inhibit cytochrome c reductases, while...

Most reported efforts to enhance production of the industrially valuable specialty chemical succinate have been done under anaerobic conditions, where E. coli undergoes mixed-acid fermentation. These efforts have often been hampered by the limitations of NADH availability, poor cell growth, and slow production. An aerobic succinate production system was strategically designed that allows E. col...
