Hypoxia Imaging and Biological Evaluation of the Radiosensitizing Effect of Oleanolic Acid

Table 1

Tumor volumes and tumor inhibition rates before and after treatment (n = 6 per group).

Group	Tumor volume (cm^3)		Tumor inhibition rate
	Before treatment	24 h after treatment
Control	0.62 ± 0.05	1.65 ± 0.09
OA	0.65 ± 0.04	1.69 ± 0.11
IR	0.62 ± 0.04	0.78 ± 0.19	52.73%
OA+IR	0.63 ± 0.08	0.81 ± 0.26	51.91%

The growth rates in IR group and OA combined with IR group were restrained after therapy. Compared with IR group: p < 0.01, p < 0.05.
