Abstract: Objective To determine the normal ranges of blood physiological and biochemical data, and to determine the body weight and the weight of organs in Cricetulus Migratorius and compare for variations of these data between the sex. Method The blood samples collected were tested for physiological values by using MEK-7222K Hematology Analyzer, biochemical values by using OLYMPUS AU400 auto-analyser. The body weight and the weight organs were determined and the organ coefficient were calculated. Result The sexual difference of 8 weeks Cricetulus Migratorius was noted in physiological values such as WBC、RBC、HGB、HCT and RDW(P＜0.05) other than MCV、MCH、 MCHC、PLT、PCT、MPV and PDW (p>0.05)，and also noted in biochemical values such as AST、 BUN、GLU and CREA(P＜0.05) other than ALT、ALB、ALP、TP、CA、P、CHO and TG (p>0.05). Sexual difference of 8 weeks Cricetulus Migratorius was noted in organ coefficient such as spleen、right kidney、right adrenal glands、lungs and heart (P＜0.05)，and also noted in organs weight such as spleen (P＜0.05). Conclusion The normal physiological, biochemical data and the organ coefficient in Cricetulus Migratorius are affected by a variety of factors. Some of the data are significantly different between the both genders.
