Summary

The effects of 5α-dihydrotestosterone (DHT) and thyroxine (T4) on glucose-6-phosphate dehydrogenase (G-6-PDH) activity in mouse submandibular gland were investigated histochemically. A strong positive histochemical reaction for G-6-PDH was observed in the excretory ducts of untreated male and female mice, with a slight reaction in the basal portion of the convoluted tubules (striated ducts) of males. Administraition of DHT to female mice increased G-6-PDH activity specifically in the convoluted tubules. T4 increased the enzyme activity in the tubules more than DHT. The induction of G-6-PDH activity by T4 in adrenalectomized mice suggests that T4 has a direct effect on the submandibular gland.
