1.电流对牙周组织中环核苷酸的影响本文的目的是通过免疫组织化学的方法研究直流电对猫牙槽骨及牙周膜中环核苷酸(CAMP-环磷酸腺苷,CGMP-环磷酸鸟苷)与组织细胞活性的关系。本实验选用九支10—12月恒牙列已完全萌出的雌猫,分三组,每组三支,任选上颌左侧或右侧尖牙接受15微安的直流电。分别用电矫治1、3、7天并观察其反应。手术过程是先肌注氯胺酮35mg/kg使猫在麻醉下于上颌第二三前磨牙近远中磨沟形成倒凹,以便带电装置的矫治器固位。取上颌印模灌人造石模型制作带电装置的矫治器。电源由五个微
1. The effect of current on cyclic nucleotides in periodontal tissue The purpose of this paper is to investigate the effect of direct current on cyclic nucleotide (CAMP-cyclic AMP, CGMP-cyclic cyclic acid Guanosine) and tissue cell activity. In this study, nine female cats with complete eruption of the permanent dentition from October to December were selected and divided into three groups of three, each with a canine of 15 microamperes on the left or right canine. Respectively electric treatment 1,3,7 days and observe the reaction. During the operation, ketamine 35 mg / kg was injected intramuscularly to make the cat under the anesthesia form a concave depression near the middle molar groove so that the appliance of the electrification device could be retained. Take the model of the maxillary impression man-made artificial stone charged appliance appliance. Power by five micro
