The cell pellets were washed with deionized water to disrupt red blood cells RBCs and the osmolarity immediately restored with 10 fold Hank' balanced salt solution HBSS. Propylthiouracil hepatotoxicity: two pediatric cases and review of the literature. Effects of PTU on plasma testosterone and T 4 in rats Male rats were divided into two groups with eight rats in each group. It is evident from the present study that PTU causes a significant decrease in the serum testosterone concentration when infused intravenously in rats. Adult testicular enlargement induced by neonatal hypothyroidism is accompanied by increased Sertoli and germ cell numbers.

However it was in the region of that used previously in rodent studies to induce hypothyroidism Hwang et al.
Cell concentration 1. Male rats were divided into two groups with eight rats in each group. Recently we found that PTU, given acutely to euthyroid rats decreases the rise in plasma corticosterone concentration induced by ACTH and that, in vitroit decreases corticosterone production in rat zona fasciculata-reticularis cells Lo et al. Hypotonic shock was repeated twice for RBC disruption and cell pellets resuspended in incubation medium substitution of HBSS in preincubation medium with Mediumand sodium bicarbonate 2.

It also decreases forskolin- and 8-Br-cyclic AMP-induced testosterone release suggesting that the drug acts directly on the rat testicular cells to regulate testosterone production at a point distal to the formation of cyclic AMP. For example, Hardy et al.
