自由基又称游离基,就是具有未成对电子的原子或原子团。近年来,国内外许多学者对自由基在生物体内的生理作用、病理机制进行了较为广泛的研究。一些研究表明,眼部的细菌感染、免疫反应和创伤均涉及到自由基。探讨自由基与眼部炎症的关系已日益引起人们的关注。 Free radicals, also known as free radicals, is an atom or group of atoms with unpaired electrons. In recent years, many scholars at home and abroad have made a more extensive study on the physiological functions and pathological mechanisms of free radicals in vivo. Some studies have shown that eye infections, immune reactions and wounds are related to free radicals. Discussion of the relationship between free radicals and eye inflammation has drawn increasing attention.
