title: The effect of hypo- and hyperthyroidism on uterine and cervical collagens and glycosidases in albino rats.
abstract: The effect of hypo- and hyperthyroidism on uterine and cervical collagen and glycosidases were studied in mature albino rats. Hypothyroidism significantly increased the salt-soluble, acid-soluble, insoluble and total collagen in the uterus and cervix. However, all of these collagens were significantly decreased in the hyperthyroid condition. The activities of alpha- and beta-galactosidases and glucosidases were significantly decreased in the uterus and cervix of hypothyroid rats, whereas, in hyperthyroid rats, all of these enzymes were significantly increased in the uterus and cervix. The data obtained in the present study suggested that the increase in lysosomal enzymes increased the degradation of uterine and cervical collagen. In contrast, the decrease in lysosomal enzymes in hypothyroid condition increased uterine and cervical collagen by decreasing degradation.
