[Effect of experimentally induced hyperthyroidism on zona glomerulosa from adrenal cortex of the rat (author's transl)].
By histochemical and histometrical methods the the effect of l-triiodothyronine on the zona glomerulosa from rat adrenal cortex was investigated. Glucose-6-phosphatedehydrogenase and 3-beta-OH-steroiddehydrogenase activities were determined in slices of adrenal cortex. No increase in activities of these enzymes was observed after treatment with l-triiodothyronine. In contrast, histometrical studies showed a significant enlargement of nuclei in the zona glomerulosa as well as in the zona fasciculata. This observation suggests enhanced secretory activity of both zones of the adrenal cortex of the rat.
