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.

Tuitoek, Prisca J.; Ritter, S.J.; Smith, J.E.; Basu, T.K. (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 ...
