Figure 8. Effect of oxytocin (10−12 to 10−7 m) on the contractile activity in myometrial tissues taken from late pregnant mice at different ages.
The effect of oxytocin (10−12 to 10−7 m) on contractile activity in the myometrium from late pregnant 3‐month‐old [LP(3), n = 32 strips from n = 8, closed circles], late pregnant 5‐month‐old [LP(5), n = 32 strips from n = 8, closed triangles] and late pregnant 8‐month‐old [LP(8), n = 32 strips from n = 8, closed squares] mice. Data are expressed as the MIT, which is the percentage increase of the baseline spontaneous activity ± SEM. Application of oxytocin at concentrations 10−12 to 10−7 m was able to augment MIT in the myometrium from mice of all ages; linear regression analysis.
