| Abstract: | We have studied testicular function in the biotin- deficient rat biochemically and morphologically. Serum testosterone and luteinizing hormone (LH) levels were decreased significantly in the deficient rats. Administration of biotin or gonadotropins to the deficient rats reversed this decrease in serum testosterone. There was no difference in the serum cholesterol level between the control and biotin-deficient rats. A significant degree of sloughing of seminiferous tubule germinal epithelium was noticed in the biotin-deficient rat testes. Biotin treatment of biotindeficient rats reversed this condition whereas testosterone treatment was without any effect. The development and maintenance of morphological and functional integrity of the seminiferous tubules appears to require a biotin-mediated step in addition to testosterone. |

| Abstract: | In pyridopaminedoxine-deficient young rats hypothalamic serum TSH concentration was detected. Highly signifiserotonin was decreased with no changes in the cant decreases in the content of pituitary TSH and in and noradrenaline content. Serum the number of pituitary thyrotroph secretory granules and tri-iodothyronine concentrations were were found. These results suo mmuuchch lower in the deficient rats as compared to thyroidism of suggest that the hypocontrols.
