[Morphometric studies of the parotid gland of rats after bilateral gonadectomy and after gonadectomy and administration of mesterone].

The influence of bilateral gonadectomy on the secretory segments of the partoid gland in male rats was investigated. The changes in the section area of cell nuclei, secretory cells, serous vesicles as well as in the mean number of cells in the vesicles were statistically analyzed. Eleven-day gonadectomy caused a statistically significant increase of the mean section area of cell nuclei, secretory vesicles and cells. Eight-day mesterone treatment in the dose of 2 mg/kg of body mass does not eliminate the changes caused by gonadectomy but results in the further increase of the mean section area of cell nuclei and secretory vesicles, as well as in the increase of cells in the vesicles.
