Abstract:
The current investigation has designed to study the role of two antidiabetics, glibenclamide and metformin on the spontaneous uterine contractions in the non-diabetic non-pregnant female rats. The rat uteri were isolated and allocated to two groups: 1) the glibenclamide group: After recording the normal spontaneous uterine contractions, the vehicle (ethanol) and glibenclamide molar concentrations (10-7, 10-6 and 10-5 M) were analyzed on uterine contractions by recording on smoked paper on a rotating kymograph drum, and 2) the metformin group: After recording the normal spontaneous uterine contractions, the metformin concentrations (10-7, 10-6 and 10-5 M) were analyzed on uterine contractions. Responses to the two drugs and vehicle control (ethanol) were recorded for 30 min. Glibenclamide has not significantly effected on the amplitude and frequency of spontaneous contractions of the isolated rat uteri. Metformin also has no significant effect on the amplitude and frequency of spontaneous contractions of the isolated rat uteri. In conclusion, the two oral antidiabetics glibenclamide and metformin have not changed both the amplitude and frequency of spontaneous uterine contractions in the non-pregnant non-diabetic female rats.
