Our results demonstrate: The structures of the organs are normal, and the shapes of cells are clearly visible. There are lots of positive brown granules in Chief cells and Parietal cells in abomasum as well as the mucosa epithelial cells and gland cells of duodenum. Three bands with a molecular mass close to 120KDa、110KD and 98KDa were identified by Western Blot. The Ob-R levels of 120KDa in abomasum were significantly higher than that of in small intestine. The levels of 110KDa were similar in the two organs. The expression of 98KDa Ob-R was weak.

Results 1、 Generally, we can see the original blue and white, shiny, no cracks in the articular surface of the cartilage after the stress increases gradually yellow, surface roughness, cracks appear; when the pressure decreases, the yellowing, rough, the color of the fracture restore gradually and become shiny.2、the shiny smooth surface can be seen under a light microscope, formation, cell distribution, tidy, clear the level of cartilage at the articular surface stress increases, the surface roughness changes, defects, disordered cells, uneven dyeing ; when the articular surface of the pressure gradually decreased, the cartilage gradually repair and the surface of cells at the surface appear only disorder.3、immunohistochemical observation can be seen throughout the observation period, cartilage cells are type Ⅱ collagen expression and expression after 3 weeks gradually weakening, when the seventh week begin to strong gradually.4、 electron microscopy shows that when stress increases the articular surface, the cartilage cells became flat, the cytoplasm in the endoplasmic reticulum, Golgi apparatus decreased with collagen disorders; and when stress decreases the articular surface, cartilage cells gradually returned normal, cytoplasm in the endoplasmic reticulum, Golgi body gradually restore quantity; collagen fibers with a gradual rules.
