A method for treating animal tissue with acylation agents to alter the net charge and net charge density of the treated tissue for therapeutic applications is provided. The method involves applying an alkaline solution to the exposed tissue surface area. This results in deprotonation of ε-amino groups of lysine residues on the exposed tissue proteins so that the tissue proteins have a net charge. Then, an acylating agent is applied and the acylating agent reacts with the tissue protein to form a protein complex having an altered net charge. Acylating agents such as sulfonic acids, sulfonyl chlorides, and acid chlorides can be used. The method can be used to treat a wide variety of human tissues including the human cornea for correcting myopia. The method can also be used to treat skin tissue, so that there is an increase in dermal thickness and pliability. The method can be further used to treat articular cartilage.
本发明提供了一种用酰化剂处理动物组织的方法,以改变被处理组织的净电荷和净电荷密度,从而达到治疗目的。该方法包括在暴露的组织表面区域使用碱性溶液。这将导致暴露的组织蛋白质上赖
氨酸残基的 ε-
氨基基团发生去质子化作用,从而使组织蛋白质带有净电荷。然后,使用酰化剂,酰化剂与组织蛋白反应,形成净电荷改变的蛋白复合物。可使用
磺酸、
磺酰氯和酸
氯化物等酰化剂。该方法可用于治疗各种人体组织,包括用于矫正近视的人体角膜。该方法还可用于治疗皮肤组织,从而增加真皮厚度和柔韧性。该方法还可用于治疗关节软骨。
