Abstract
Influence of hyperprolactinaemia, induced endogenously by anterior pituitary transplantation on rat hepatic and renal cortical and medullary phosphomonoesterases and adenosine triphosphatases (ATPases) has been investigated. Although prolactin has a stimulatory effect on phosphomonoesterases and ATPases, it exhibits a specific and temporal influence on each subtype of hepatic and renal ATPases and phosphomonoesterases at different durations of pituitary transplantation. The specific activities of alkaline phosphatase and Na(+)-K+ dependent ATPases are activated in all the regions of different durations of experimentation. However, acid phosphatases, Ca2+ and Mg2+ dependent ATPases exhibit a differential response to prolactin in renal cortex, medulla and liver. Direct influence of prolactin on hepatic and renal phosphomonoesterases and ATPases is thus suggested.
