Table 2

TMR of each group before and after treatment. (n = 6 per group).

Group	TMR		ΔTMR
	Before treatment	24 h after treatment
Control	1.28 ± 0.08	2.78 ± 0.16	117.18%
OA	1.29 ± 0.16	2.61 ± 0.22	102.32%
IR	1.28 ± 0.06	1.24 ± 0.32	- 3.12%
OA+IR	1.30 ± 0.07	1.15 ± 0.13	- 11.54%

TMR was the lowest in the OA combined with IR group among the four groups after therapy. Compared with IR group: p < 0.01, p < 0.05.
