The effects of nickel, cobalt, chromium and zinc on the content of vitamins A, E and C, malondialdehyde (MDA), chlorophyll and carotenoids were investigated in bean seedlings (Phaseolus vulgaris L.) grown in Hoagland solution Control and heavy metal-treated plants were grown for ten days in Hoagland solution. Vitamin A, E, and C content were measured in primary leaves by high performance liquid...

nitrite intoxication occurs frequently in ruminants and equines. the most common treatment of this disorder is administration of 1% methylene blue, although the use of some antioxidant agents e.g. vitamins and complementary treatment may also be useful. the aim of this study was to evaluate the in vitro antioxidative effects of some vitamins on methemoglobinemia induced by sodium nitrite. for t...

objective(s) oxidized low-density lipoproteins (ox-ldls) appear to play a significant role in atherogenesis. in fact, circulating ox-ldl concentrations have been recognized as a risk factor for cardiovascular disease (cvd). the main objectives of this study were to assess the effects of antioxidant vitamins on ox-ldl as a biomarker of cvd in male subjects with cvd risk factors. materials and me...

BACKGROUND Virtually all plants and animals protect themselves from the sun using vitamins C and E. OBJECTIVE The purpose of this study was to see if a combination of topical vitamins C and E is better for UV protection to skin than an equivalent concentration of topical vitamin C or E alone. METHODS We developed a stable aqueous solution of 15% L-ascorbic acid (vitamin C) and 1% alpha-toco...

Oxidative stress has been suggested as a contributory factor in development and complication of diabetes. Diabetic nephropathy is a serious complication of diabetes mellitus. Oxidative stress has been suggested to play a key role in the pathogenesis of diabetic nephropathy. The aim of the study is to evaluate the effect of Vitamins – E & C (VEC) roles in the antioxidant defense system. It is li...

The antioxidant effects of vitamins C and E on cryptorchidism-induced oxidative stress were investigated in male Sprague-Dawley rats. Forty rats (200-250 g) were randomly divided in a blinded fashion into five groups (n = 8). Group 1 was sham operated and treated with vehicle (corn-oil, 10 mL/kg). Groups 2, 3, 4, and 5 were rendered unilaterally cryptorchid and treated with vehicle (10 mL/kg), ...

Concentrations of the naturally occurring antioxidant vitamins A, C and E were measured in 27 patients with Parkinson's disease and 16 age-matched control subjects, from a similarly disabled patient group. There was no significant difference in the serum concentrations of vitamins A and E in the two groups. Vitamin C was significantly higher (P < 0.05) in the Parkinson's disease group, however,...

BACKGROUND The aim of is to determine the association of vitamins with glaucoma by performing a systematic review and meta-analyses. METHODS Studies on the relation of vitamins and glaucoma published up to December 2017 were identified in the PubMed and Embase database. Data on vitamins (method of assessment), glaucoma (type and method of assessment), study characteristics and quality were re...

Problem statement: Patients with active pulmonary Tuberculosis (TB) are malnourished as indicated by reductions in lean mass, anthropometric indices and micronutrient status. Supplementation with vitamins may prove to be beneficial. Limited information is available on the supplementation of vitamin C and E in pulmonary TB patients. Hence, the present study was undertaken to address the question...

The association between dietary antioxidant vitamin intake and the risk of breast cancer was examined in a prospective study of 34,387 postmenopausal women in Iowa. Intakes of vitamins A, C, and E and of retinol and carotenoids were assessed in 1986 by mailed semiquantitative food frequency questionnaire. Through December 31, 1992, 879 incident breast cancer cases occurred in this cohort. There...
