一些文献报道ＮＯ与肝硬变门静脉高压症（ＣＰＨ）高动力循环有关，但诱生型一氧化氮合成酶（ｉＮＯＳ）基因ｍＲＮＡ在ＣＰＨ胃粘膜中的表达情况及酶的活性变化尚不十分清楚，为此我们进行了该方面研究，结果报道如下。 材料和方法 １．动物模型和标本的采集 雄性ＳＤ大鼠３０
It has been reported in some literatures that NO is associated with hyperdynamic circulation of cirrhotic portal hypertension (CPH), but the expression of inducible nitric oxide synthase (iNOS) mRNA in gastric mucosa of CPH and the change of enzyme activity are not yet clear , For which we conducted a study in this area, the results are reported below. Materials and methods 1. Animal models and specimens were collected from male SD rats 30
