title: Vitamin C status, glutathione and histamine in gastric carcinoma, tuberculous enteritis and non-specific ulcerative colitis.
abstract: Studies were conducted to evaluate the blood levels of ascorbic acid, dehydroascorbic acid, glutathione, and histamine in patients with gastric carcinoma, tuberculous enteritis and non-specific ulcerative colitis. Leucocyte ascorbic acid, urinary excretion of total ascorbic acid and ascorbic acid saturation test were also carried out in order to assess the ascorbic acid status of these patients. It was observed that the plasma and leucocyte content of ascorbic acid was significantly lower with markedly decreased urinary excretion in these patients. Further urinary excretion of ascorbic acid after a test dose was also found to be subnormal. Decreased levels of glutathione and significantly higher levels of histamine reflect an overall reducing status of the body is markedly deranged.
