thromboxane-b2 and Cholelithiasis

This paper reports the treatment with Yiqi Huoxue and Shugan Liqi agents in atherosclerosis of rabbit. The results suggested: 1. Both decoctions could reduce the cholesterol of hypercholesterolemia and improve the atherosclerosis, but the former was better than the latter. 2. Both decoctions could alter the components of bile lipids, but on the contrary, the latter was better than the former in reducing the formation of gallstones. 3. Both decoctions could decrease the plasma concentration of LPO and ratio of TXB2/6-K-PGF1 alpha, while increase the ratio of cAMP/cGMP in plasma. So, the different prescriptions of TCM affecting the same link of pathogenesis might play the role of "Different Treatments in Same Disease".

The changes of the plasma thromboxane B2 (TXB2) and 6-keto-PGF1 alpha, the stable metabolites of TXA2 and PGI2, respectively and their effects on platelet counts, platelet aggregation and hypotension were studied in patients with AOSC. The results showed that the plasma TXB2, 6-keto-PGF1 alpha and 6-keto-PGF1 alpha/TXB2 ratios in these patients were markedly increased, however, the platelet counts markedly decreased and platelet aggregation inhibited significantly. After operation, they recovered to normal gradually. There were negative correlation between TXB2 with platelet count and 6-keto-PGF1 alpha with platelet aggregation, as well as both TXB2 and 6-keto-PGF1 alpha with blood pressure. TXA2 was an important factor which lead to platelet decrement and take part in the pathological course of disseminated intravascular coagulation (DIC) and multiple organ failure (MOF), but PGI2 might play an important role in improving microcirculation and preventing DIC and MOF through the inhibition of platelet aggregation.
