Effect of exogenous prolactin on ultrastructure of pinealocyte in female pigs during puberty.
Influence of the administration of prolactin to female swine during puberty on the ultrastructure of pinealocytes has been examined by means of morphometric analysis. Prolactin administration for 15 consecutive days resulted in a decrease in the cytoplasmic dense bodies type MBB-2, lysosomes and multivesicular bodies. Some differences in structure of pinealocytes were also observed. Prolactin appeared to stimulate the process of transformation of cytoplasmic dense bodies.
