The chemical constituents of pod of Gleditsia sinensis Lam. have been studied.The saponin, fibrin, half fibrin, xylogen and proteins of it have been mensurated.
The necrotic epithelium becomes embedded in exuding fibrin and red and white cells,so that a grayish pseudomembrane is formed-commonly over the tonsils,pharynx or larynx.
The high levels of urea irritate the serous pericardium, making it secrete a thick pericardial fluid that's full of fibrin strands and white blood cells.
Over time, the inflammation destroys the intervertebral joints, as well as the facet joints, and the sacroiliac joints, and fibroblasts replace the destroyed joint with fibrin.
This leads to fluid exudation and deposition of fibrin in the alveoli, resulting in a destructive pneumonia that obliterates the air spaces and compromise respiratory function.
