炎症是一种临床常见的病理过程。根据现代病理学定义:炎症是具有血管系统的活组织对损伤因子发生的以防御为主的反应。这种反应体现在炎症的渗出和/或增生过程中,特别是渗出中。因此,炎症的本质是防御、是抗损伤。 炎症的原因是多种多样的,可归纳为生物性因子、物理化学因子和免疫因子等。总之,凡能造成组织和器官发生一定程度的损伤反应的因子皆可为炎症因子。 Inflammation is a common clinical pathological process. According to the definition of modern pathology: Inflammation is the defensive reaction of living tissue with vasculature to injury factors. This reaction is manifested in the infiltration and / or hyperplasia of inflammation, especially exudation. Therefore, the essence of inflammation is defense, is anti-injury. The causes of inflammation are diverse and can be summarized as biological factors, physicochemical factors and immune factors. In short, any factor that can cause a certain degree of damage to tissues and organs may be an inflammatory factor.
