| Abstract: | The effects of histamine on the spontaneous activity of the isolated human myometrium were studied. Both the frequency and force of contractions of the muscle strips were not significantly altered by histamine. The presence of either a histamine H1-or H2-receptor antagonist in the organ bath did not significantly change the responses of the uterine muscle to histamine. These findings suggest that histamine has negligible effects on the human myometrium, possibly due to the absence, or paucity, of histamine receptors. |
