Quail high uric acid hematic disease animal model was set up.Observed in twenty-two days,blood was tested blood uric acid,xanthine oxidase,creatinine(CRE),urea nitrogen(BUN),triglycerides(TG),low density lipoprotein cholesterol(hdl-c),xanthine high density lipoprotein hdl oxidase(XOD),hepatic lipase(HL),lipoprotein lipase(LPL),adenosine dehydrogenase(ADA)lipid metabolism index,joints and kidneys for histopathological examination.Results: Model control group animals blood uric acid were significantly increased (P0.01), CRE,BUN,TG, LDL and XOD were significantly increased(P0.05or P0.01), serum CHO、LPL、ADA、HDL content significantly decreased (P0.05).Animal toes jointed obvious swollen after building, surrounding soft tissue swelling. X-ray showed toes bone density decrease, part of the joint surface damage is dissolved bony destruction.
