this study was evaluated to study the effects of vitamin c and the bacteria bacillus subtilis, b.lichniformis on growth and carcass composition of litopenaus vannamei. three treatments were applied, treatment fed with probiotics (4×1010 cfu/kg food), treatment with vitamin c (140 mg/kg food) and the control group. three replicates were used for each treatment. shrimps were kept in nine 300-lite...

In this research the effect of conventional and ohmic pasteurization and storage time at different temperatures on some bioactive components of Aloe vera gel juice was investigated. Aloe vera gel juice was pasteurized conventionally and ohmically at 90 ºC for 1 min. The effect of pasteurization on vitamin C, total phenolic content  and juice color was evaluated. The samples pasteurized conv...

objective(s) bone is a dynamic tissue that is continuously renewed throughout life by the process of bone remodeling. antioxidant system might be involved in the pathogenesis of bone loss, so the aim of this study was to evaluate the total antioxidant capacity (tac), vitamin c and vitamin e levels of plasma besides measuring enzymatic antioxidants, superoxide dismutase (sod), catalase (cat) and...

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...

the effect of different concentration of salicylic acid (0, 1 and 2 mmoll-1) and chitosan (0, 0.5 and 1 percent) on postharvest life and quality of selva strawberry fruit during storage at 2.5±0.5°c with 85-95% rh for 7 and 14 days was studied. decay incidence, marketability, total soluble solids, total acidity, vitamin c content and total antioxidant activity were evaluated during storage. chi...

Background and Objective: Acrylamide is a highly soluble, widely- produced industrial and cytotoxic material. Some substances with antioxidant properties can ameliorate the deleterious effect of acrylamide. Vitamin C is necessary for the normal functioning of all cells and scavenging the free radicals due to the antioxidant properties. The present study was aimed to evaluate the effect of vitam...

a sensitive procedure for determining total vitamin c (ascorbic acid + dehydrate ascorbic acid) in a blood drop from a finger prick, before and after the adminis- tration of a vitamin c tablet is described. analysis was carried out by high per- formance liquid  chromatography with  electrochemical detection (hplc/ec). measurements were taken one hour, two hours and six hours after the administr...

conclusions in conclusion, we have shown that vitamin c administration provides protection against csa-induced injury in rat liver function and may have hepatoprotective role in the patients experiencing csa treatment. background cyclosporine a (csa) is an important immunosuppressive agent; however, its clinical use is limited by several side effects such as hepatotoxicity. vitamin c (ascorbic ...
