Effect of angiotensin II and corpuscle of Stannius extract on total and ionic plasma calcium levels and blood pressure in intact eels (Anguilla rostrata Lesueur)

Abstract

A comparison of the effects of angiotensin II and saline extract of the corpuscles of Stannius on plasma electrolytes and blood pressure in eels was carried out. Angiotensin II caused an increase in plasma ionic calcium and blood pressure but had no effect on total plasma calcium or sodium. Corpuscular extract caused a decrease in plasma ionic calcium but had no effect on the other parameters. These findings indicate a possible role of the corpuscular secretions in binding plasma ionic calcium.
