Strain variation in vitamin A (retinol) status of streptozotocin-induced diabetic rats.
(International Journal for Vitamin and Nutrition Research, 1996)Decreased plasma concentrations of vitamin A (retinol) and retinol-binding protein have been previously identified in human subjects with type I diabetes mellitus. The present study was undertaken to investigate the effects ... -
Streptozotocin-induced diabetes in rats is associated with impaired metabolic availability of vitamin A (retinol).
(The British Journal of Nutrition, 1996-04)Using streptozotocin-induced diabetic Wistar rats, studies were carried out to examine the metabolic availability of vitamin A in the plasma, liver and the retina of the eye. Control and diabetic rats were fed ad lib. on ... -
Streptozotocin-induced diabetes lowers retinol-binding protein and transthyretin concentrations in rats.
(The British Journal of Nutrition, 1996-12)Retinol-binding protein (RBP) and transthyretin (TTR) in the plasma, liver and kidney, retinol in plasma, and total vitamin A in the liver were measured in rats 6 weeks after diabetes mellitus had been induced by streptozotocin ... -
