The aim of the study was to assess the pharmacokinetic and biopharmaceutical effect of ascorbic acid (Vitamin C) on pefloxacin on concurrent administration in man through urine excretion data and microbiological evaluation. A two way crossover study was performed in ten healthy male volunteers aged (Mean ± SD) 45 ± 5.5 years and weight (Mean ± SD) 75.4 ± 12.5 Kg recruited and given pefloxacin 4...

Vitamin C, an antioxidant substance soluble in water, can react with amino groups of proteins to form schiff bases. As diabetes leads to glycation of various protein which has effect on structure and biochemical activity of them, the inhibition of this process seems very vital. For several years researches in this field have done their best to recognize the antidiabetics compounds. The aim of t...

this experiment was conducted to evaluate the effects of vitamin c on laying hens performance, egg characteristics and some blood parameters under normal rearing condition. one hundred and ninety two 24 - weeks - old laying hens diet were used in a completely randomized design with 4 treatments (0, 250, 500 and 750 mg vitamin c/kg diet) and 4 replicates for 105 days. although feed consumption, ...

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...

in this study the chemical properties of b6c4si and c16 clusters connected vitamin c have been investigated using density functional theory (dft). nmr parameters and homo- lumo gap energy are calculated by using density functional method (b3lyp) with 6-311g* basis set. calculations show that homo- lumo gap energy of vitamin c decreases after connecting to b6c4si or c16 cluster decreasing of hom...
