四君子汤、四逆散及甘麦大枣汤均可提高慢性应激大鼠的免疫功能，不同程度地降低大鼠血浆ACTH、下丘脑CRH及血浆CORT的含量，并可降低慢性应激大鼠下丘脑CRH mRNA和垂体ACTH mRNA的过量表达。

The SPC-2S fraction with 30% EtOH were constituted epicatechin and epicatechin gallate ester ;The SPC-2S fraction with 50% EtOH contained epicatechin and dimeric procyanidins, another SPC-3S contained epicatechin ,dimeric procyanidins and trimeric procyanidns ;Dimeric procyanidins and trimeric procyanidns constitute SPC-5S fraction;monomer dimer trimer tetramer pentamer of procyanidins were the major fractions in 70% acetone elute solution.

1和 2.01：1，也以添加0.1%SPC酒样中两者的比例最为协调；对小曲酒中酸的影响表现为，添加SPC后有利于降低酒样中乙酸的含量，各酒样中乙酸的量随着SPC添加量高粱外种皮中原花青素及其对小曲白酒挥发性成分影响机制研究的增加而降低；对醛类的影响为，添加SPC可降低酒样中糠醛的含量，其中以添加 0.1%SPC酒样中含量最低，为对照组的39.3%，而4个酒样中乙醛含量则无明显差别；低SPC添加量有降低酒样中杂醇油含量的趋势。

The results show that a proper air - entraining agent to be added not only can increase strength of cement polystyrene board effectively, but also decrease its density. The fly ash to be used instead of part of cement can save cement consumption and lower production cost under the prerequisite to ensure the property of cement polystyrene board.
