title: The effect of prostaglandin E2 on the cardiovascular response to angiotensin II in pregnant rabbits.
abstract: The rise in arterial blood pressure in response to angiotensin II was studied in the last third of pregnancy in rabbits. The response was compared with that of pregnant rabbits during infusion of prostaglandin E2 and F2alpha. Prostaglandin E2 significantly diminished the rise in diastolic pressure in response to angiotensin II. Prostaglandin F2alpha did not alter the response. Intravenous indomethacin elevated the blood pressure and caused an absolute increase in the pressor response. It did not mediate a change in the percentage rise in blood pressure in response to angiotensin II.
