Changes in contractile parameters in response to NaHS, GYY4137 and GYY4137 with Glibenclamide, in term pregnant rat myometrium.

Term (day 22) rat myometrial strips were studied from 4–7 animals. After baseline values were obtained (10 minute period immediately before incubation in experimental solutions, 100%), tissues were incubated in either physiological saline (control) or the solutions indicated, for 45 minutes and then the parameters of contraction re-measured, and expressed as the percent of baseline values (i.e. paired data).Values are means ± s.e.m.*represents significant differences in contractility compared to preceding control period (p
