The theory is cell kinetics and mechanism of drugs.

主要是根据细胞动力学原理和药物的作用机理分析，如果把药物集中应用，一方面只是一过性的杀灭增殖期的白血病细胞，对静止期细胞影响不大，另一方面对正常细胞造成较大损伤，而如果药物作用于几个细胞增殖周期，对白血病细胞进行几个循环的打击，会清除更多白血病细胞，而对正常细胞损伤较小。

Of 92 acutely dissociated dorsal root ganglion cells recorded by current patch-clamp technique, 34% were discharged by FA application with the mean onset latencies of the first action potential being (367.34+/-32.96) s. All the FA-sensitive cells were identified as nociceptor cells by their distinguishable features of AP including longer duration, existence of a hump on the repolarizing phase, and longer after-hyperpolarization of APs.

In an attempt to evaluate the safety and efficacy of Healon in trabeculectomy, 20 eyes with Healon and 20 eyes without Healon injection after trabeculectomy are compared. Trabeculectomy using Healon will not induce transient rise of intraocular pressure. By filling the anterior chamber with Healon, a tamponing effect results which will maintain a deep chamber and reduce complications such as flat anterior chamber, choroidal detachment and striate keratopathy in the early postoperative period. In long-term evaluation there is no difference in pressure control, conjunctival scarring and corneal endothelial cell loss between Healon group and Non-Healon group.关键词 trabeculectomy , flat anterior chamber , choroidal detachment , intraocular pressure

为了评估Healen在小梁切除术中之疗效及安全性，选20位接受小梁切除术者，同时注射Healon於前房为实验对象，另20位接受传统小梁切除术为对照组，发现使用Healon并不会引起一过性眼压上升的现象，Healon注入前房，产生填塞作用，最大的好处是可以维持前房深度，减少术后合并症如前房消失，脉络膜剥离及角膜水肿等，然长期追踪，对於降眼压的幅度，不因使用Healon而可达到低眼压状态，也不会减少结合膜瘢痕化而促进房水引流，然Healon系一无毒，无炎性，无抗原性高黏稠性的物质，不因使用而发生炎性反应，同时有保护角膜内层细胞的功能。
