Fingerprints of broiler chickens divergently selected for very low den sity lipoprotein in fat line and lean line of the third generation were studied using inter simple sequence repeated technique. Geneti c polymorphism and genetic similarity coefficient between two groups were analyze d. Ten primers were screened from 60 SSR primers and 62 sites were deprived. Of which 39 bands were polymorphic sites and the frequency was 63 percent.

METHODS:Forty cases of traumatic optic neuropathy were analyzed retrospectively. Univariate analysis (Chi-square test) and logistic regression were performed to filter the risk factors to the visual prognosis of traumatic optic neuropathy. Eight variables were tested, including corticosteriod treatment in 2 days after trauma,no light perception,frontal or temple trauma,orbital hemorrhage and/or fracture,disturbance of consciousness,age ,other ocular trauma and presence of blood within the sphenoidal or ethmoidal sinus.
