Abstract:
Objective To explore the influence of drug dosage, solvent and other main influencing factors on the successful establishment of alloxan-induced hyperglycemia mouse model and the effect on the stability of this model. Methods 160 6-8-week-old Kunming mice ofSPF grade, (male:female=1:1) were used in this study.The influences of different dosages of alloxan and solvent combinations on the successful establishment rate of the model, survival rate, body weight, fasting blood glucose, blood glucose area under curve, serum insulin level and their stabilities were dynamically observed for six weeks.Results By single intraperitoneal injection of 160 mg/kg bw alloxan ( pH 4.5 citrate sodium as solvent) , we were able to obtain a stable experimental hyperglycemic mouse model with higher levels of successful establishment rate (70%), survival rate (75%), fasting blood glucose (15-20 mmol/L), glucose area under the curve (55-65 mmol/L) and a lower but not loss of serum insulin levels (21 mIU/L).Conclusions In the present study we have carefully considered the influence of main factors such as drug dosages, solvent, etc., on the alloxan-induced experimental hyperglycemic mouse model, and successfully established this model after 6-week period observation of its stability.This model may provide a useful tool in the research of experimental diabetes and hypoglycemic functional studies.
