HISI treatment prolong the survival time of mice in toxic condition induced by sodium nitrite and duration of electrocardiograph in trachea closed mice .HISI could obviously improve the ischemic electrocardiogram T-wave induced by Pituitrin.ST segment drifts on electrocardiogram in acute myocardial ischemia rats induced by Isoprotereno were obviously opposed by administration of HISI. The myocardial infarction areas, releasement of lactic dehydrogenase 、 creatine phosphokinase significantly increased in myocardial ischemia dogs, HISI treatment prevented these effects .

蛋白酪氨酸磷酸酯酶HA2（PTPase，HA2），一个PTPase 1B的同源酶，在3T3-L1前脂肪细胞诱导分化成脂肪细胞的调控过程中起着重要作用。

When chinese wampee seeds were naturally desiccated, the content of soluble sugar in seeds increased, and the content of starch in seeds decreased. In the meantime, the activities of phosphorylase and isocitrate lyase in seeds, and of α-and β-amylase in embryonic axes enhanced initially, and then fell.

自然脱水时，黄皮种子中可溶性糖的含量增加，淀粉含量下降；磷酸化酶，异柠檬酸裂解酶以及胚轴中α-和β-淀粉酶的活性先增加然后下降：子叶中α-和β-淀粉酶的活性呈下降趋势。

Studies also indicated that genistein exsists not only in soybeans but also in many kinds of plants such as vegetables and fruits.As a potential anticancer agent, the actional mechanisms of genistein mainly includes as follows:First, genistein can depress the activity of protein tyrosine kinase and transduction pathways for the phosphorylation of receptors and mitosis signal. So genistein can lead to cells' proliferation depressed. Second, genistein has minimal effects of phytoestrogens. It can be combined with estrogen receptor and improve the synthesis of cellular sex hormone binding glulobin, and improve the activity of UDP-glucuronyl transferase. Through these pathways, it can inhibit the cell activity of breast cancer and prostate cancer.

作为一个很有潜力的抗肿瘤物质，三羟异黄酮的作用机制主要包括：①抑制蛋白酪氨酸激酶活性，可阻抑PTK引起的受体磷酸化和有丝分裂的信号传递，导致癌细胞增殖受抑；②弱雌激素作用：可通过与体内雌激素受体结合，并可增加细胞内性激素结合球蛋白的合成，增加UDP-葡糖醛酸转移酶的活性等途径抑制乳腺癌和前列腺癌细胞活性；③拓扑酶Ⅰ和Ⅱ抑制剂，抑制细胞活性；④上调细胞周期性负性调节因子P21WAF1/CIP1的表达，使之负性调节因子作用增强；⑤可阻止胰岛素样生长因子-Ⅰ、肝细胞生长因子和神经生长因子的作用而抑制肿瘤生长；⑥其他：抗氧化作用、抑制热休克蛋白、诱导细胞凋亡、抑制新生血管生成和抑制多种耐药相关蛋白等。
