Vitamin B6 and arteriosclerosis.

In 1949, Rinehart and Greenberg reported that marked arteriosclerosis occurs in vitamin-B6-deficient monkeys. The present study investigates the relationship between vitamin B6 and arteriosclerosis and summarizes the results. I found that thrombogenesis, disorder of collagen metabolism and production of free radicals may be the processes that cause arteriosclerosis in human and experimental ani...

Tryptophan metabolism in vitamin B6-deficient mice.

Vitamin B6 deficiency was induced in mice by maintenance for 4 weeks on a vitamin B6-free diet. Tryptophan metabolism was assessed by determining the urinary excretion of tryptophan metabolites, the metabolism of [14C]tryptophan in vivo and the formation of tryptophan and niacin metabolites by isolated hepatocytes. The vitamin B6-deficient animals excreted more xanthurenic acid and 3-hydroxykyn...

Vitamin B6 deficiency in cancer patients.

The plasma pyridoxal phosphate concentration was determined in 30 cases of early breast cancer, 21 patients with locally recurrent disease, and 43 patients with systemic metastases. The two groups of advanced breast cancer had significantly lower plasma pyridoxal phosphate levels than 36 healthy women of similar age. Urinary 4-pyridoxic acid excretion was normal in breast cancer. Plasma pyridox...

Electrolyte imbalance in vitamin B6-deficient rats.

The importance of vitamin Bs in water metabolism has been studied extensively. Stebbins (1) demonstrated an impaired water metabolism in animals deprived of vitamin Be. Lepkovsky and colleagues (2) suggested that derangement of water metabolism may be involved in the occurrence of fits in vitamin B&-deficient rats. Guggenheim (3) observed that rats in a state of vitamin Be deficiency show a del...
