Methods: 55 New-Zealand rabbits were randomly divided into control group (n=13), model group (n=14), direct moxibustion group (n=14) and herb-medicine-cake-separated moxibustion (indirect moxibustion) group (n=14). Hyperlipemia model was established by feeding the animals with specialized forage (15% vitellus powder, 5% lard, 0.5% cholesterol and common forage) for 6 weeks. Moxibustion was applied to “Juque”(CV 14), “Tianshu”(ST 25), “Fenglong”(ST 40), etc., 4 moxa-cones for every acupoint, once daily and continuously for 40 days. Serum high density lipoprotein-cholesterol (HDL-Ch), low density lipoprotein-cholesterol (LDL-Ch) and total cholesterol (TCh) contents were assayed with colorimetric method. Results: Compared with control group, serum LDL-Ch content, HDL-Ch/LDL-Ch and HDL-Ch/TCh of model group were significantly higher (P<0.05～0.01), while compared with model group, LDL-Ch contents of two moxibustion groups were strikingly lower (P<0.01). No significant differences were found between two moxibustion groups in all the 4 indexes. Conclusion: Both direct and indirect moxibustion can effectively lower serum LDL-Ch, raise HDL-Ch, HDL-Ch/LDL-Ch and HDL-Ch/TCh, and regulate lipoprotein metabolism in hyperlipemia rabbits.展开更多

Methods: The hyperlipemia rabbit model was established by breeding of high fat forage and injection of bovine serum albumin. They were treated respectively by direct moxibustion and herbal cake-separated moxibustion at Juque (巨阙 CV 14), Tianshu (天枢 ST 25), Fenglong (丰隆 ST 40), etc., once daily, continuously for 40 days. Blood TCh and TG contents were detected with enzymatic method, LDL-Ch and HDL-Ch with colorimetric method, Apo A and Apo B with electrophoretic method, and TXB2 and 6-keto-PGF 1α with radioimmunoassay. Results: Both the herbal cake-separated moxibustion and direct moxibustion could effectively decrease TCh, TG, LDL-Ch, Apo B and TXB2 contents and TXB2/6-keto-PGF 1α, and increase HDL-CH and 6-keto-PGF 1α contents in the rabbit of hyperlipemia. Conclusion: 6-keto-PGF 1α and TXB2 are possibly involved in the mechanism of herbal cake-separated moxibustion decreasing blood lipids.展开更多
