The effects of acetylsalicylic acid on the pituitary prolactin of the lizard, Uromastix hardwickii.

This study deals with the intravenous administration of 7 mg acetylsalicylic acid (ASA) solution to Uromastix hardwickii for 4 days. It enhances the activity of anterior pituitary lactotrophs, when 0.1 ml of pituitary homogenate of ASA treated was injected hypodermically to crop-sac showed a greater diametric response and increased activity with milk like secretion than that of the injections of 0.1 ml homogenate of control pituitary. The present study indicated that ASA induces hyperprolactinemia.
