本文报告40例突发性聋，其超氧化物歧化酶（SOD）明显低于对照组（P＜0.01），而过氧化脂质（LPO）及空腹血糖（FBG）明显高于对照组（P＜005或P＜0．001）。指出突发性聋不仅有自由基及空腹血糖的变化，而且SOD下降与FBG增高有密切关系，并提示自由基的损害作用可能是突发性聋发生的一个重要病理生理环节。
In this paper, 40 cases of sudden deafness were reported, the superoxide dismutase (SOD) was significantly lower than that of the control group (P <0.01), but LPO and fasting blood glucose (FBG) <005 or P <0.001). It is pointed out that sudden deafness not only has the change of free radicals and fasting blood glucose, but also the decrease of SOD is closely related to the increase of FBG. It also suggests that the damaging effect of free radicals may be an important pathophysiological link of sudden deafness.
