活化

Transformation into active enzymes occurs as one or more peptide bonds in the zymogen are cleave d.

活化作用即是打断原分子内的一个或多个键。

Protein phosphorylation and dephosphorylation and zymogen activation are two very important regulation mechanism for enzyme activity and function.

Objective: To study the effect of "Yiqitiaoxue, fubenpeiyuan" Acup Therapy on selective neuron lost of Senile Accelerated Mouse P8, a model of AD, treated with acupuncture. Observe the number and sharp of neuron in the hippocampus and the cortex of temporal lobe, activation and accrementition of horizontal cell, as well as the expression of apoptosis relative protein. Discusse the possible mechanism of acupuncture in neuroprotective effect.

目的：以快速老化模型小白鼠SAMP8为阿尔茨海默病(Alzheimer&s disease， AD，老年性痴呆)动物模型，通过观察针刺对该小鼠海马和颞叶皮质神经元数量以及神经元形态、星形胶质细胞的活化增生、凋亡相关蛋白的表达的影响，研究&益气调血，扶本培元针法对AD选择性神经元丢失的干预作用及其机制，为针刺治疗AD提供神经病理学实验依据。

Gelatin zymography was used to detect the activation and secretion of MMP-2 and MMP-9 in gastroenemius、soleus、plantaris during early、intermediate and final stage of experimental group. Picric- sirius red polarized light was used to detect the accrementition and reconstitution of mesenchymal fibers in the muscle specimens from the operated group and normal controls.
