EFFECT OF ZINC SUPPLEMENTATION ON HYPERPROLACTINAEMIA IN URAEMIC MEN

Abstract Zinc and prolactin levels were measured in 32 male haemodialysis patients; 12 were receiving 50 mg zinc per day as zinc acetate and 20 were not. Zinc-treated patients had significantly higher plasma zinc levels (134±10 μg/dl v 88±2 μg/dl) and lower serum prolactin levels (11±4 ng/ml v 29±7 ng/ml) than untreated patients. Plasma zinc and serum prolactin were inversely related in zinc-treated and untreated patients ( r = -0·79, p
