Effects of the Chinese Drugs for Activating Blood Circulation on Plasma TXB2 and 6-Keto-PGF1α Contents in Rabbits withGlucocorticoid-induced Femoral Head Necrosis

In the femoral head necrosis model rabbit induced by endotoxin combined with methylprenisolone, the dynamical changes of plasma TXB2 and 6-keto-PGF1αcontents were observed. As a result, microscopic examination showed that in the model group, bone trabeculae became fine, empty bone lacunae increased,and osteoblasts in number decreased; the ratio of TXB2 and 6-keto-PGF1α was out of balance, and these changes worsened gradually with the lapse of time; Compound Sheng Mai Cheng Gu Capsules (复方生脉成骨胶囊) could reverse femoral head necrosis, protect the vascular endothelial cells, recover the balance of TXB2 and 6-keto-PGF1α. It is concluded that the hormone-induced femoral head necrosis is closely related with blood stasis, and that the Chinese drugs for activating blood circulation and removing blood stasis can prevent the femoral head from development of necrosis.

Effects of acupuncture on the levels of endothelin, TXB2, and 6-keto-PGF1 alpha in apoplexy patients.

In order to delve into the mechanism governing the treatment of apoplexy by acupuncture at yangming channel points as main points, we observed the changes in the endothelin (ET) level in plasma, TXB2 and 6-Keto-PGF1 alpha levels in urine in convalescent apoplexy patients during acupuncture treatment. The results showed that the ET level in plasma in convalescent apoplexy patients was significantly higher than that in healthy subjects (P < 0.05), and the ET level in plasma in patients was decreased after one course of acupuncture treatment. It was found that before treatment the TXB2 level in urine in apoplexy patients was significantly higher than in healthy subjects, and the 6-Keto-PGF1 alpha level in urine in the patients was significantly lower than that in healthy subjects, with an increased ratio of TXB2 to 6-Keto-PGF1 alpha. After acupuncture treatment, the TXB2 level in urine was lowered with a decrease in the ratio of TXB2 to 6-Keto-PGF1 alpha. All this indicated that one of the mechanisms governing acupuncture treatment of apoplexy acupuncture at yangming channel points as main points was that acupuncture could produce therapeutic effects by adjusting the imbalance of important vaso-active substances, ET, TXA2, and PGI2.

Effects of nifedipine and Paeonia lactiflora on plasma TXB2 and 6-Keto-PGF1 alpha in cholesterol-fed rabbits

The authors examined the influences of nifedipine and Paeonia lactiflora (PL) on plasma LPO, TXB2 and 6-keto-PGF1 alpha in cholesterol-fed rabbits. In this study, oral administration of nifedipine (15 mg/kg per day) and PL (0.5 g/kg per day) with 2% cholesterol diet for 15 weeks caused 60.75% and 74.24% reduction in the lesion area of aorta respectively. The levels of plasma LPO, TXB2, cholesterol, phospholipid and calcium of the intimalmedia of the aorta in the treated groups were significantly lower than those in the control group, but the level of 6-keto-PGF1 alpha in the treated groups was significantly higher. The durations of TXB2 elevation and 6-keto-PGF1 alpha reduction were delayed. The ratio of TXB2/6-keto-PGF1 alpha tended to balance. The ratio of TXB2/6-keto-PGF1 alpha was significantly positive correlation with the percentage of lesion area of the aorta. It is demonstrated that calcium metabolism plays an important role in thromboxane, prostaglandin, and LPO synthesis. In conclusion, the inhibition of LPO production and the regulation of TXA2-PGI2 balance may be one of the mechanisms of anti-atherogenesis of calcium antagonists and PL.

Effect of jiang-zhi zhong-yao-pian on total cholesterol, triglyceride, TXB2, 6-keto-PGF1 alpha in hyperlipemic patients

The purpose of this study was to verify the effect of a Chinese herbal medicine Jiang-Zhi Zhong-Yao-Pian to reduce serum lipoid. Efficacy was observed in 30 cases of hyperlipemia; 20 cases administered with evening primose oil capsules were taken as controls. Each group took drugs for two or three months. The results were as follows: After treatment as compared with before treatment, the serum levels of TC, TG and TXB2 dropped from 264.28 +/- 70.52 mg%, 393.52 +/- 250.42 mg% and 110.75 +/- 43.52 pg/ml to 225.60 +/- 50.93 mg%, 264.97 +/- 252.81 mg% and 88.82 +/- 46.50 pg/ml respectively (P less than 0.001, less than 0.01, less than 0.05). However, in the group taking evening primrose oil capsules, TC, TG and TXB2 in comparing with the pre-treatment levels were changed from 251.33 +/- 58.24 mg%, 316.35 +/- 104.93 mg% and 131.53 +/- 49.77 pg/ml to 244.30 +/- 43.28 mg%, 272.10 +/- 92.52 mg% and 115.33 +/- 47.49 pg/ml respectively (P greater than 0.05, less than 0.05, greater than 0.05). This medicine had no side-effect. The results showed that the herbal formula might be useful to reduce serum TC, TG and TXB2.
