摘　　要：环氧化酶(COX)主要有COX-1和COX-2两种异构酶,前者是一种"管家酶",后者是一种可诱导酶。多种因素会调控COX基因表达。机体受到伤害性刺激后,外周和中枢COX异构酶表达均发生变化,激活COX-PG级联反应,产生具有重要功能的PG类物质,PG与相应受体相结合,调控痛觉过敏。非甾体类药物通过外周和中枢双重抑制COX异构酶,通过改变前列腺素类物质的量,发挥抗伤害效应。The cyclooxygenase,genase （COX） has two types of isomerase,ie. COX-1 and COX-2. COX-1 is a ＂housekeeper enzyme＂ and COX-2 is an inducible enzyme. Multiple factors regulate the expression of COX gene. After nociceptive stimulus imposing on the organism,the expression of both two isoforms varies in the peripheral and central nervous system activating the COX-PG cascade reaction, which induce a series of prostaglandins （PGs） with many important fuctions. PGs regulate organic hyperalgesia by combination with the homologous receptors. The nonsteroidal anti-inflammatory drugs （NSAID） generate antinociceptive effects by inhibiting the cyclooxygenase in the peripheral and central nervous system and alterating the amount of prostaglandins.
