Methods： A total of 72 male Sprague-Dawley （SD） rats were randomly divided into a normal group （n=8）, a model group （n=32） and a moxibustion group （n=32）. According to the times of modeling or treatment, the model group was further randomly divided into different subgroups of a 1-time model subgroup, a 4-time model subgroup, a 7-time model subgroup and a 10-time model subgroup （n=8）; the moxibustion group was also further randomly divided into different subgroups of a 1-time moxibustion subgroup, a 4-time moxibustion subgroup, a 7-time moxibustion subgroup and a 10-time moxibustion subgroup （n=8）. Rats in both model and moxibustion subgroups were subjected to establishing the swimming exhaustive model. Rats in each moxibustion subgroup received mild moxibustion at Shenque （CV 8） for 15 min immediately after modeling, once every other day. The concentration of malic dialdehyde （MDA）, as well as the activities of superoxide dismutase （SOD）, glutathione peroxidase （GSH-Px） and total antioxidant capacity （T-AOC） in rat＇s hippocampus in each group were detected 24 h after the exhaustive exercise. Results： Compared with the 1-time model subgroup, the exhaustive swimming time of rats was significantly prolonged in the 4-time model subgroup （P〈0.01）, while it was significantly shortened in the 7-time and 10-time model subgroups （both P〈0.01）. Compared with the matched model subgroup, the exhaustive swimming time of rats in the 7-time and 10-time moxibustion subgroups was significantly prolonged （both P〈0.01）. Compared with the normal group, the MDA concentration was increased significantly （P〈0.01）, and the activities stress response of SOD and T-AOC were increased in the 1-time model subgroup （both P〈0.05）; the MDA concentration was increased （all P〈0.01）, and the activities of SOD, GSH-Px and T-AOC were decreased differently （P〈0.05 or P〈0.01） in the 4-time, 7-time and 10-time model subgroups. Compared with the matched model subgroup, the concentration of MDA was significantly reduced （P〈0.05 or P〈0.01）, and the activities of SOD, GSH-Px and T-AOC were significantly increased in the 4-time, 7-time and 10-time moxibustion subgroups （all P〈0.01）. Conclusion： Moxibustion at Shenque （CV 8） can improve the fatigue status of the body after long-term exhaustive exercise by regulating free radical metabolism in rat＇s hippocampus. To some extent, this provides an experimental basis for moxibustion at Shenque （CV 8） against exercise-induced fatigue.展开更多

Methods: Fifty-six male Sprague-Dawley (SD) rats were randomly divided into a blank group (n=8), an exhaustive group (n=24), and a moxibustion group (n=24). The exhaustive group was randomly divided into a 1-time exhaustive group, a 4-time exhaustive group and a 7-time exhaustive group, with 8 rats in each group. According to the treatment time, the moxibustion group was randomly divided into a 1-time moxibustion group, a 4-time moxibustion group and a 7-time moxibustion group, with 8 rats in each group. Rats in the exhaustive groups and the moxibustion groups were subjected to replicating the exhaustive swimming models. Rats in each moxibustion group received mild moxibustion for 15 min immediately after the exhaustive modeling, once every other day. Twenty-four hours after the corresponding exhaustive exercise, the rats in each group were tested for the levels of serum immunoglobulin (Ig) G, IgA, IgM and acid phosphatase (ACP), and the morphological changes of spleen tissues were observed. The level of IgA was detected by immunoturbidimetric assay, and the levels of IgG, IgM and ACP were detected by en zyme-linked imm uno sorb ent assay (ELISA). Results: Compared with the 1-time exhaustive group, swimming time of rats in the 4-time exhaustive group was significantly proIonged (P<0.01), and swimming time of rats in the 7-time exhaustive group was significantly shortened (P<0.01). Compared with the 7-time exhaustive group, exhaustive swimming time of rats in the 7-time moxibustion group was significantly proIonged (P<0.01). Compared with the blank group, the IgG level in the 1-time exhaustive group was significantly decreased (PvO.Ol), and the levels of IgG, IgA and IgM in the 4-time exhaustive group and the 7-time exhaustive group were all sign ifica ntly decreased (P<0.05 or PvO.Ol), while the ACP level was in creased sign ifica ntly (both P<0.01). Microscopically, the number of splenic corpuscles in the 1-time exhaustive group was reduced;the center of some splenic corpuscles in the 4-time exhaustive group was damaged;the number of splenic corpuscles in the 7-time exhaustive group was reduced, and there was no obvious germinal center. Compared with the 4-time exhaustive group, the IgA level in the 4-time moxibusti on group was sign ifica ntly in creased (P<0.01), and the ACP level was sign ifica ntly decreased (P<0.01). Compared with the 7-time exhaustive group, the levels of IgG, IgA and IgM in the 7-time moxibustion group were sign ifica ntly in creased (all PvO.Ol), and the ACP level was sign ifica ntly decreased (P<0.01). Microscopically, the nu mber of splenic corpuscles in the 1-time moxibustion group was reduced;the center of some splenic corpuscles in the 4-time moxibustion group was damaged together with hyperplasia of some splenic corpuscles;blast cells were proliferated in the center of some splenic corpuscles in the 7-time moxibustion group. Conclusion: Moxibustion at Shenque (CV 8) can improve the levels of IgG, IgA and IgM, reduce the ACP level, repair damaged spleen tissues, and enhance the immunity of the body to some extent in the Iong-term fatigue rats.展开更多
