Hyperlipemia rabbit models established with high cholesterol and fat diet were treated with direct moxibustion and medicinal cake-separated moxibustion. The post-treatment plasma 6-keto-prostaglandin F1α (6-keto-PGF1α) and thromboxane B2 (TXB2) contents were determined by radioimmunoassay. Results indicated that the plasma 6-keto-PGF1α content significantly increased, the TXB2 level decreased (P＜0.05)and the TXB2 /6-keto-PGF1α ratio also decreased (P＜0.01) in the medicinal cake-separated moxibustion group as compared with those in the model group respectively, but there was no significant difference between the medicinal cake-separated moxibustion group and the direct moxibustion group (P＞0.05),suggesting that both the medicinal cake-separated moxibustion and direct moxibustion can regulate the plasma 6-keto-PGF1α and TXB2 contents, and the TXB2/6-keto-PGF1α ratio with similar actions, and have a certain protective action on endothelial cells of the aorta in the rabbit of hyperlipemia.
