Influence of thyroidectomy on seminal vesicular glycosidases of young albino rats.

ABSTRACT

Impact of thyroidectomy (hypothyroidism) on few glycosidases was studied in the seminal vesicles of young albino rats. Thyroidectomy was performed at 30 days post partum. Seminal vesicular beta-D-glucosidase, beta-D-galactosidase, and N-acetyl-beta-D-galactosaminidase exhibited a similar response of decreased activities under short- (30 days) and long-term (60 days) hypothyroid conditions. On the other hand, N-acetyl-beta-D-glucosaminidase registered a temporal biphasic response of increased and decreased activities in the seminal vesicles of rats subjected to short- and long-term hypothyroidism, respectively. The data obtained in the present study suggest that thyroid hormones have specific influences on different glycosidases in the seminal vesicles of rats and euthyroid status is essential for the maintenance of normal activities of these enzymes.
