ABSTRACT
Purpose. To determine whether moxibustion influences the learning and memory behavior of ApoE-/- male mice, and investigate the mechanism of moxibustion on the alteration of oxidized proteins (glial fibrillary acidic protein, β-amyloid) in hippocampus. Methods. Thirty-three ApoE-/- mice were randomly divided into 3 groups (n = 11/group): moxibustion, sham moxibustion, and no treatment control. Wild-type C57BL/6 mice (n = 13) were used for normal control. Moxibustion was performed with Shenque (RN8) moxibustion for 20 minutes per day, 6 days/week for 12 weeks. In sham control, the procedure was similar except burning of the moxa stick. Behavioral tests (step-down test and Morris water maze task) were conducted in the 13th week. The mice were then sacrificed and the tissues were harvested for immune-histochemical staining. Results. In the step-down test, the moxibustion group had shorter reaction time in training record and committed less mistakes compared to sham control. In immune-histochemical study, the moxibustion group expressed lower level of GFAP and less aggregation of β-amyloid in the hippocampus than the sham control. Conclusion. Our findings suggest that moxibustion may enhance learning capability of ApoE-/- mice. The mechanism may be via inhibiting oxidized proteins (GFAP and β-amyloid) in astrocytes.

(b) The graph shows different levels of β-amyloid; thus it can be seen that normal control group got less area of Congo staining for β-amyloid than that of no treatment control group. Same situation occurs between sham moxibustion group and moxibustion group. *P < 0.05 versus no treatment control group; ΔP < 0.05 versus sham moxibustion group.

Mentions: Moxibustion group showed a remarkable decrease of β-amyloid plaque level compared with sham moxibustion group. No treatment control group developed higher amyloid plaque level than normal control group, which proved the existence of significant difference (Figure 5).
