(A) Changes in mouse body weights prior to and following BSHXF administration. Prior to modeling, the weights of the mice in the control, model and BSHXF-treated groups were 21.024±1.353, 20.700±1.287 and 20.588±1.113 (P>0.05). Following modeling, the body weights were markedly reduced in the model group compared with the control. At the end of the 6-week experimental period, the body weights were 24.108±0.861, 23.612±0.564 and 22.984±0.903 for the control, model and BSHXF-treated groups, respectively, and the body weight in the model group was significantly decreased compared with that in the control and BSHXF-treated groups (P<0.01). (B) Changes of organ indices prior to and following BSHXF administration. The index values in the control, model and BSHXF-treated groups were: Thymus index: 2.619±0.371, 2.220±0.235 and 2.400±0.305 mg; spleen index: 3.543±0.227, 3.767±0.476 and 3.520±0.409 mg; uterus index: 3.561±0.149, 2.854±0.825 and 3.018±0.640 mg; ovary index: 0.498±0.164, 0.382±0.043 and 0.465±0.137 mg. *P<0.05 and **P<0.01 vs. the control group; ##P<0.01 vs. the model group.
