Human chorionic gonadotropin attenuates the vascular response to angiotensin II.

Objective: Our purpose was to investigate interactions between human chorionic gonadotropin (hCG) and angiotensin II (ANG II) in resistance arteries.

Study Design: Isolated pre-arteriolar vessels of female Sprague-Dawley rats were prepared from the mesenteric arcade and the mesometrium. Dose-response curves were recorded by means of an video-electronic arteriograph system.
