Oral sucrose tolerance tests of OSM. A blood glucose concentrations and B area under curve (AUC) during oral glucose tolerance tests in 16 h-fasted rats. Areas under the curve of blood glucose were compared. Data are presented as means ± standard deviation (n = 6). Bars labeled with different superscripts have significantly different values at 5% using Duncan’s Multiple Range Tests (DMRT, p < 0.05). a–c, the different letters indicated significant differences among the groups by a Tukey test in each time point at P < 0.05
