摘　　要：目的探讨消化性溃疡及糜烂性胃炎与前列腺素、血栓素及幽门螺杆菌的关系．方法用放免技术，测定消化性溃疡（ｎ＝５３）、糜烂性胃炎（ｎ＝５５）患者及正常人（ｎ＝５４）血浆中前列腺素（６ｋｅｔｏＰＧＦ１α）、血栓素（ＴＸＢ２）的含量，并胃粘膜活检组织学查幽门螺杆菌（Ｈｅｌｉｃｏｂａｃｔｅｒｐｙｌｏｒｉ，Ｈｐ）．结果溃疡组及糜烂性胃炎组ＴＸＢ２含量及ＴＸＢ２／６ｋｅｔｏＰＧＦ１α的比值均明显高于对照组（Ｐ＜００１），两组的６ｋｅｔｏＰＧＦ１α的含量与对照组无差异（Ｐ＞００５）．两组患者中Ｈｐ（＋）与Ｈｐ（－）之间的６ｋｅｔｏＰＧＦ１α，ＴＸＢ２的含量及ＴＸＢ２／６ｋｅｔｏＰＧＦ１α的比值均无差异（Ｐ＞００５）．结论ＴＸＡ２与ＰＧＩ２失衡可能与溃疡的发病密切相关。IM To explore the relationship among 6ketoPGF-1α, TXB-2 and H.pylori in peptic ulcer and erosive gastritis.METHODS Serum levels of 6ketoPGF-1α and TXB-2 were measured by using radioimmunoassay in patients with peptic ulcer (n=53), erosive gastritis (n=55), and normal controls (n=54). All patients were tested by histology to determine whether he (she) was infected with H.pylori.RESULTS The serum TXB2 level and the ratio of TXB-2/6ketoPGF-1α were significantly higher in peptic ulcer and erosive gastritis than that in normal subjects. There was no obvious difference among the three groups in 6ketoPGF-1α. There was also no obvious difference in TXB-2, 6ketoPGF-1α and the ratio of TXB-2/6ketoPGF-1α between the groups of Hp(+) and of Hp(-).CONCLUSION The imbalance of TXA-2PGI-2 is involved in the pathogenesis of peptic ulcer, and there is no relationship between H.pylori and prostaglandin.
