Influence of prolactin on neural and glial cellular adenosine triphosphatases in immature male bonnet monkeys (Macaca radiata, Geoffroy).

ABSTRACT

The effect of prolactin on specific activities of adenosine triphosphatases (ATPases) in neural and gliar cells of cerebral cortex, cerebellum and pons-medulla of immature male bonnet monkeys was studied. Na+, K+ dependent ATPase was stimulated, while Mg2+ and Ca2+ dependent ATPase activities showed reduction in neural as well as glial cells of cerebral cortex and cerebellum. However, in pons-medulla, Na+, K+ and Mg2+ dependent ATPases showed the same trend in neural and glial cells, respectively, as in the other two regions. The data obtained reveal that prolactin has specific effect on different ATPases, in different regions of the brain.
