血栓素B_2(TXB_2)和6-酮-前列腺素F_(1α)(6-keto-PGF_(1α))分别为血栓素A_2(TXA_2)和前列环素(PGI_2)的稳定性代谢产物。后两者间的平衡变化与心脑血管等疾病关系密切。因此从流行病学角度测定TXA_2和PGI_2两种物质在老年期的变化,探
TXB_2 and 6-keto-PGF_ (1α) were the stable metabolites of thromboxane A_2 (TXA_2) and prostacyclin (PGI_2), respectively. After the balance between the changes and cardiovascular and other diseases are closely related. Therefore, from the perspective of epidemiological determination of TXA_2 and PGI_2 two substances in old age changes, exploration
