Enzymes of glycolysis (hexokinase,lactate dehydrogenase,aldolase) showed low activities during overwintering when more carbon flowing into treh alose synthesis.

越冬期间体内糖原磷酸化酶活性明显地增加，糖酵解有关的酶（己糖激酶、乳酸脱氢酶和醛缩酶）活性较低，以保证更多的碳源转化成海藻糖。

Methods Myocardial ischemia was induced by subcutaneous injection of ISO (30 mg/kg for two days, once a day). The experimental animals were randomly divided into the normal group, ISO group, positive control group and three crocetin groups (25, 50, 100 mg/kg). Cardiac indexes were examined. The level of LDH, CK, MDA in serum were measured. The content of MDA, GSH-Px and the ATPase activity heart and mitochondria were assayed by colorimetric analysis. The histopathological change of myocardia was investigated by HE staining.

采用大剂量ISOsc诱导产生大鼠急性心肌缺血模型(1SO30mg／kg，每日一次，连续2d)，实验大鼠随机分为正常组、ISO模型组、阳性对照组和3个西红花酸给药组(25，50，100mg／kg)，测定心脏系数和血清中乳酸脱氢酶、磷酸肌酸激酶和丙二醛含量，观察心肌组织谷肮甘肤过氧化物酶、Na^ ，K^ —ATP酶和Ca^2 ，Mg^2 —ATP酶活性及心脏病理改变，观察西红花酸的保护作用。

This method conformed the following conditions: spleen phosphodiesterase and micrococcal nulcease for digesting reagent and the concentration, temperature and digesting time of the two enzymes;the components of p32-post label alleviant and labeling time;the concentration of p1 nuclease; the concentration of T4 polynucleotide kinase for catalysing and labeling reagent;the components of bidirectional spreader and the spreading time ,etc.

确定了采用脾磷酸二酯酶和微球菌核酸酶消化底物以及两种酶的使用浓度、温度及消化时间；确定了P32标记缓冲液的主要成分及标记时间；确定了P1核酸酶的浓度；确定了T4多核苷酸激酶催化标记底物的浓度；确定了双向展开剂的主要成分及展开时间等。

Compared with the ck, the sugar accumulation increased extremely significant by grafting with the wild watermelon 2, but that of the other treatments all decreased and the sugar accumulation of loofah/Zaojia was the lowest. The sucrose invertase activity decreased; the activitives of sucrose phosphate synthase and net for sucrose-metabolism enzymes all increased during the development of own-rooted and grafted watermelons.

与对照相比，野生西瓜2号／早佳组合的果实糖积累极显著增高，而其他嫁接组合的糖积累均降低，丝瓜／早佳组合的果实糖含量最低；自根和嫁接西瓜果实发育过程中蔗糖转化酶活性降低，蔗糖磷酸合酶活性升高，蔗糖合酶在西瓜果实发育后期主要起合成作用，促进果实蔗糖积累，蔗糖代谢相关酶净活性值增大。
