Abstract: Objective To measure the indexes of biological characteristics of organ weight an organ coefficient of tree shrew.Methods 27 tree shrews(15females and 12 males)were chosen,and the body weight and 6 organs' weight were determined,then the organ coefficients were counted.Results Between female and male tree shrew,the brain weight showed significant difference(P<0.01)and the difference of heart,liver was obvious(P<0.05).The coefficient of brain and kidney had remarkably significant difference(P<0.05).Linear analysis showed that there were obvious linear relations between body mass and the weight of heart,liver,kidney in female tree shrew;there were linear relation between body weight and heart in male.Conclusion Differences existed in heart weight,liver weight,brain weight,brain coefficient,kidney coefficient between female and male tree shrew,and there had linear relationships between body weight and some main organs.
