Contraction frequencies and amplitudes of the normal uterine of estrogen-primed non-pregnant rats were monitored. A decline in the frequencies of uterine contractions of 43.8 - 93.6% was detected. Addition of Fire Ha Kong at the final concentrations of 20-40 µl/ml inhibited the amplitudes of uterus contraction by 57.1% and 85.7%, respectively. The reductions in area under the curve (AUC) of contractions were 57.1% and 85.7% for the added concentrations. Fire Ha Kong recipe revealed inhibitory effects on the uterine response to oxytocin (10-11 M) 31.9% and 29.3% only in frequency but not in amplitude and AUC in comparison to oxytocin alone. These results indicate that the tocolytic potential of Fire Ha Kong recipe may involve oxytocin receptor-dependent pathway or reduce the intracellular availability of calcium ions.</Abstract> <AbstractLanguage>English</AbstractLanguage> <Keywords>Fire Ha Kong recipe uterine contractions in vitro test rat oxytocin</Keywords> <URLs> <Abstract>https://aaspjournal.org/ubijournal-v1copy/journals/abstract.php?article_id=5932&title=In vitro uterine relaxant activity of Fire Ha Kong Recipe in rats</Abstract> </URLs> <References> <ReferencesarticleTitle>References</ReferencesarticleTitle> <ReferencesfirstPage>16</ReferencesfirstPage> <ReferenceslastPage>19</ReferenceslastPage> <References/> </References> </Journal> </Article> </ArticleSet>
