Abstract
The aim of this investigation was to compare the response of small arteries of the human tubo-ovarian vasculature to certain vasoactive agents. Ring preparations of the arteries were isolated and mounted in tissue chambers for isometric recording of wall tension. The arteries were exposed to the vasoactive agents adrenalin, prostaglandin F2 alpha and two vasopressin analogues. Adrenalin, prostaglandin F2 alpha, lysin-vasopressin and triglycyl-lysine-vasopressin all produced powerful vasoconstriction, the greatest efficacy being shown by and lysine-vasopressin. The maximum response occurred after addition of a third compound to a combination of two, irrespective of which combination was used. Adrenalin showed faster contraction velocity than the other agents. The results indicate that the human tubo-ovarian arteries may be constricted by a variety of physiological and pharmacological stimuli, at least partly acting via different effector mechanisms. It is proposed that these vasoconstrictive agents--alone or in combination--may be useful in conjunction with gynaecological endoscopic surgery, e.g. in tubal pregnancy or ovarian cysts.
