Increases in blood flow and vascular permeability are responsible for local swelling (edema), redness, and heat. Pain is due mainly to the action of chemical mediators on nerve endings. Chemotaxis (Gr. chemeia, alchemy, + taxis, orderly arrangement), the phenome non by which specific cell types are attracted by some molecules, is responsible for the migration of large quantities of specific cell types to regions of inflammation. As a consequence of chemotaxis, leukocytes cross the walls of venules and capillaries by diapedesis血細(xì)胞滲出 , invading the inflamed areas. 纖 維 ( fiber) 纖維 ( fiber) 分類 膠原纖維 彈性纖維 網(wǎng)狀纖維 形狀 顏色 電鏡結(jié)構(gòu) 分布 肌腱、韌帶、L C T 椎間盤、彈性軟骨 基膜、器官支架 功能 韌性大抗拉力 彈性大 支架 具嗜銀性 膠原纖維的組裝 1和 3型膠原蛋白 原膠原 膠原纖維 臨 床 聯(lián) 系 Medical Application In progressive systemic sclerosis進(jìn)行性系統(tǒng)性硬化病 , almost all ans may present an excessive accumulation of collagen .This occurs mainly in the skin, digestive tract, muscles, and kidneys, causing hardening and functional impairment of the implicated ans.
