  1. D-2 refers to 2 days before the day of the first treatment (D1), D1PRE to just before the first treatment, D1POST to immediately after the first treatment, D5 to 5 days after the first treatment, D7PRE to just before the second treatment, and D7POST to immediately after the second treatment. Data are presented as the mean (SEM). Mean values followed by different letters (a, b) indicate a significant difference of experimental period within SMT group. Boldface * represent p < 0.05
