We present a simple approach to determine the content of casein in crosslinked polyacylamide, i. e., protein molecules are complexed with copper ions by biuret reaction. The polymer containing proteins is cinerated at high temperature and then the residue is dissolved into nitric acid. Protein content is measured by determining concentration of copper ion in nitric acid solution using atomic absorption spectrum.

It is postulated that IP induces the release of endogenous protective molecules that interact with cognate receptors to activate PLC through mediation of the chincough virus sensitive proteins. PLC hydrolyzes membrane phospholipid and produces diacylglyccerol,that,by working together with calcium hydronium,translocates PKC from cytoplasm to cell membrane and activates PKC.

推测缺血预处理细胞保护作用机制是：缺血预处理引起内源性保护物质释放，作用于细胞膜上的相应受体，通过百日咳病毒敏感性G蛋白的介导而激活磷脂酶，磷脂酶水解膜磷脂，产生二酰基甘油(diacylglyccerol，DAG)，DAG和Ca2+协同作用于PKC，使其从胞浆转位到细胞膜并且被活化，PKC在膜上使底物蛋白磷酸化，引发一系列相关信号转导通路的激活，调控保护性基因的表达，从而提高细胞对缺血再灌注损伤的耐受性。

The method controls the catalytic speed of the microencapsulation glucose oxidase through adjusting the molecular weight and the degree of deacetylation of microcapsule exine chitose, thereby the method is beneficial for oxidation-linking of gluten protein and for increasing the quality of the flour and flour products, simultaneously, the glucose oxidase after microencapsulation avoids the contact between enzyme and the flour and improves storage and the stability, and the microencapsulation glucose oxidase is excellent flour modifying agent and accords with practical production and application.
