近年来在进行药物离子导入时已开始采用整流的正弦电流。认为,在整流后的正弦电流和直流电作用时间相同,平均电流量相等时,前者能将更多的药物导入体内。并指出这与正弦电流每一个脉冲具有更高的电位有关。另一些作者的实验得出了相反的结果。作者考虑到这个问题很重要,因此比较了在整流的正弦电流和直流电作用下离子移动的数量。实验是在一个改进的电泳槽中进行的,药物是胰蛋白酶。0.007%的胰蛋白酶盐酸溶液(pH3.0)注入中间槽内,并用
In recent years, the introduction of drug ions have begun to use the rectified sinusoidal current. It is considered that the former can introduce more drugs into the body when the rectified sinusoidal current and the direct current have the same acting time and the average current amount is equal. It is pointed out that this is related to the fact that each pulse of the sinusoidal current has a higher potential. Other authors’ experiments yielded the opposite result. The author considers that this issue is important and therefore compares the amount of ion movement under rectified sinusoidal and dc currents. The experiment was carried out in a modified electrophoresis tank, the drug was trypsin. 0.007% trypsin hydrochloric acid solution (pH3.0) into the middle tank, and use
