Histamine H2 receptor mediated relaxation of hamster (Mesocricetus auratus) uterus.
Histamine and 4-methyl histamine produced relaxation of KCl depolarized hamster uterus in vitro. The relaxation was selectively antagonized by histamine H2 receptor antagonist cimetidine which failed to antagonize the isoprenaline induced relaxation. The histamine induced relaxation was, further, not mediated through catecholamine release. The study indicated that, as in the albino rat, histamine produces relaxation of the hamster uterus mediated via the H2 receptors.
