The experimental result shows:1 acupuncture and moxibustion on DU4 and RN4 can lighten inflammationreact , suppress the inflammation course, DU4 has the best result.2 IL-2 is the important factor of participating the immune respondence.Acupuncture and moxibustion can increase IL-2 content in the blood , thusstrengthen the immune function of the organism .3 acupuncture end moxibustion can raise β-EP content of lower thalamus ,hypophysis , lymph gland. it proves that acupuncture and moxibustion can stimulateand accelerate compound、store 、process 、shifting utility of β-EP content; andstrengthen the immune regulating function of the organism, acupuncture function isstrong rapidly, moxibustion function is slow and gentle, the regulating action powerof moxibustion has close relations with choice of the point . The possible reason isthat y whether acupuncture and moxibustion bring into play their regulating actionthrough different way of neural body fluid.4 The DU4、RN4、FEI point influence rule apply on change of β-EP content ofabove-mentioned organism.

实验结果显示：1 针灸命门和关元穴能减轻炎症反应，抑制炎症过程，命门穴效果最好。2IL-2 是参与免疫应答的重要因子，而针灸能增加血中 IL-2 含量，从而增强机体的免疫功能。3 针刺和艾灸可以升高下丘脑、垂体、淋巴结β-内啡肽含量，说明针灸可以刺激并加速β-内啡肽含量合成、储存加工和转移利用；增强机体的免疫调节功能，针刺作用迅速强烈，艾灸作用缓慢温和，艾灸的调节作用强弱还与穴位的选择有密切关系。

The objective of this study is aimed at the implementation of parallelized numerical quadrature routines. The algorithm we choose for numerical quadrature routines is the so called "Adaptive Romberg Tree integration scheme"(abbr."ARTint") proposed by Lin et. al.[1997]. This numerical quadrature scheme can arrange the function evaluation points adaptively in accordance with characteristic of the trend of variation in integrand function values. When the accuracy of the numerical quadrature value is requested to be increased, a newer and larger set of function evaluation points must be incurred. The main advantage of ARTint method is the inclusion of all function evaluation points used in previous stages. It is this feature of ARTint method that makes it a quadratue scheme with prominent computation efficiency.
