Abstract:
Objective:To investigate the effect of moxibustion at Shenque (CV 8) on free radical metabolism in rat's hippocampus after different degrees of exhaustive exercise.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.
