When pH is below 1 0, DNA denaturalization of pEGFPC3 was prominent and there was hardly protection by β-cyclodextrin.

结果 pH 1 0的酸液对pEGFPC3质粒DNA的变性作用最强，pH 1 5～ 2 5的酸液对其有部分变性作用，pH 1 5～ 2 。5范围内β-环状糊精对质粒DNA具有较为明显的保护作用，对于pH 1 0的情况仍不足提供相应的保护。

When high temperature is used to denature DNA, the DNA is said to be melted.

DNA 变性后，生物活性丧失，但一级结构没有改变，所以在一定条件下仍可恢复双螺旋结构。

This could be done in practice by using an alkaline CsCl gradient, as the two DNA strands will denature at high pH.

用同样的样品和相同的技术手段即CsCl梯度离心将半保留复制和弥散复制区分开来的方法是将DNA样品变性，然后利用碱性CsCl梯度离心技术对单链DNA进行离心，半保留复制会出现两条带，而若是弥散复制则出现一条带，如下图所示

METHODS: A limb ischemia-reperfusion injury model in rats was established. The animals were randomly divided into three groups: control group, IR group and IPC group. The contents of diamide oxidase, nitric oxide, endothelin-1 (ET-1) and ratio of nitric oxide/endothelin-1 (NO/ET-1) in the plasma and the gut were measured. The leavels of myeloperoxidase, ratio of DNA chain, total nitric oxide synthase, inducible nitric oxide synthase and constitutive nitric oxide synthase in the gut were determined.

雄性Wistar大鼠18只，随机分为对照组，缺血再灌注组和缺血预适应组，每组6只，分别测定血浆和小肠组织二氨氧化酶、一氧化氮、内皮素-1(ET-1)、NO/ET-1比值的含量变化及小肠组织的髓过氧化物酶、DNA双链百分率(ratio of DNA chain %)、总一氧化氮合酶、诱导型一氧化氮合酶、结构型一氧化氮合酶的水平；免疫组化法检测小肠组织的诱导型一氧化氮合酶、内皮型一氧化氮合酶的表达。
