Using non-diabetic control and streptozotocin-induced diabetic male Wistar rats of 4-6 week duration, the metabolic availability of vitamin A (retinol) was examined. Animals were fed ad libitum a nutritionally complete ...

The objective of the project was to determine the effects of level of fat with or without manganese supplementation of diets on protein status of humans. Fourteen healthy adult humans participated in a 61 day study in which ...

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 ...

A Using streptozotocin-induced diabetic rats, we examined the effects of zinc supplementation and insulin treatment on the metabolic availability of vitamin A. All diabetic animals exhibited an elevated plasma glucose (>18 ...

Diabetes mellitus is known to be associated with enhanced intestinal absorption of lipids. A validated in vitro technique was used to examine the uptake of (3H) retinol (a lipid soluble vitamin) into the jejunum and ileum ...

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 ...

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 ...
