Since no reliable functional markers of human vitamin C status have been demonstrated, de termination of vitamin C levels in blood plasma and/ or leukocytes remains the current choice for individual and population assessments. Newer analytical tech niques, especially high-performance liquid chromatography, allow determination of reduced (ascorbic acid), oxidized (dehydroascorbic acid), or total...

The vitamin C content of human milk was determined among twenty-six newly delivered mothers. Milk samples (colostrum, transitional and mature) were obtained at different stages of lactation. Mean vitamin C concentration varied from 3.52 ± 0.56 mg/dl for colostrum to 3.03 ± 0.67 mg/dl for mature milk with the advancement of time, but was in agreement with the infant's daily requirement. Serum vi...

Background and Aim: Organophosphate insecticides such as diazinon (DZN) can disrupt the body's antioxidant defense system. Antioxidants protect cells against oxidative stress. In the present study, antioxidant properties of N- acetylcysteine (NAC) and vitamins E and C in reducing oxidative stress caused by DZN in rat spleen were compared. Materials and Methods: In this experimental study,...
