| Abstract |
|
A study has been carried out of the effects of prolactin, aldosterone, and corticosterone on osmoregulation in three species of freshwater terrapin. The results suggest that the main action of prolactin may be to increase the GFR with subsequent changes in ion excretion. Aldosterone has been shown to stimulate potassium excretion and reduce the urinary Na/K ratio in normal animals and also to reduce the sodium excretion in salt-loaded terrapins. The results with spironolactone suggest it may mimic aldosterone rather than antagonise its action when administered in high doses. Corticosterone had a similar effect to aldosterone causing an increase in potassium excretion and a decrease in the Na/K ratio.
