The experiment analyses the esterase volume of Catecholamines and Acetylcholine in blood,nervous tissue and spleen tissue by way of Chromatography With Electrochemical Detection,detects the volume of aminophenol nervoustransmmiter in nervous tissue by way of automatic amino acid analyzer,and reflects the immunity function of spleen by using the spleen index,the cabability of T lymphopoiesis of spleen,the sub-T lymphocyte of blood.

应用高压液相色谱—电化学检测法和生化比色法分别分析血液、神经组织和脾脏组织中的儿茶酚胺和乙酰胆碱酯酶含量，应用氨基酸自动分析仪检测神经组织中的氨基酸类神经递质含量，以脾脏系数、脾脏T淋巴细胞增殖能力、血液T淋巴细胞亚型等指标反映脾脏的免疫机能。

Result and Conclusion: Macr oporous resins D301 can be used in the process of adsorbing and purifying active compounds of danshensu and protocatechualdehyde, and increase the amount of act ive compounds in water extracts.

结果 ：D301树脂能够有效的吸附丹参素和原儿茶醛。结论：采用D301树脂可以作为改进分离纯化工艺，去除杂质，提高粗提物中有效成分含量。

The effect of aqueous ethanol (50% v/v) on the activity of purified mushroom polyphenol oxidase has been found to be as follows:(1)The oxidation of catechol or pyrogallol is greatly stimulated,an increase in the rate of oxygen uptake of over 100% having been invariably observed with catechol as the substrate,whereas the oxidation of other substituted o-dihydric phenols is inhibited in 50% ethanol.

三无论有无抗坏血酸的存在，50%乙醇对多酚氧化酶活力的提高程度是一样的，在有一定量的抗坏血酸的存在下，多酚氧化酶对儿茶酚的 Michaelis 常数(25℃)在水溶液及50%乙醇溶液中各为0.072×10~(-3)M 及0.49×10~(-3)M。

In the negative and interrogative forms, of course, this is identical to the non-emphatic forms.
