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...
متن کاملRenal glutaminase activities in vitamin B6-deficient rats.
Glutamine has been implicated in the functioning of the central nervous system (l), in muscle metabolism (a), in transamination (3), in detoxification (4), and as a precursor of urinary ammonia (5). An excellent review of these and other possible r&es of glutamine in metabolism has been presented by Archibald (6). It would seem that glutamine acts as a mobile reserve of ammonia and glutamic aci...
متن کاملTryptophan 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...
متن کاملEndogenous oxalate synthesis and glycine, serine, deoxypyridoxine interrelationships in vitamin B6-deficient rats.
Attempts to study the etiology of diseases associated with oxaluria or oxalate deposition or both, have been handicapped by the misconception that very little urinary oxalate is endogenous in origin. However, Gershoff et al. (1) have demonstrated oxalate nephrocalcinosis and oxaluria in vitamin Be-deficient cats. In vitamin Bc-deficient rats consuming diets free from oxalate, renal calculi of c...
متن کاملPlasma homocysteine and liver tissue S-adenosylmethionine, S-adenosylhomocysteine status in vitamin B6-deficient rats.
OBJECTIVE The aim of this study was to evaluate plasma homocysteine (Hcy), malondialdehyde (MDA), glutathione (GSH) levels, glutathione peroxidase (GSH-Px) and glutathione-S-transferase (GST) activities and liver tissue S-adenosylmethionine (SAM) and S-adenosylhomocysteine (SAH) levels in control and vitamin B6-deficient rats. MATERIALS AND METHODS Thirty-two male rats with a weight of 65-75 ...
