ABSTRACT
OBJECTIVE:
To study the hypoglycemic effects of Insulin self-microemulsion for parenteral administration on mod-el rats with type 1 diabetes in vivo.METHODS:
Rats were treated with streptozotocin(50 mg/kg)to reproduce model with type 1 diabetes,ip. The model rats were randomly divided into model group (normal saline),positive control group (Insulin injection 2.25 u/kg) and self-microemulsion low,medium and high dose groups (Insulin self-microemulsion 4.5,9 and 18 u/kg);and 10 normal rats were involved in sham-operation group (normal saline). Anesthesia and operation were conducted for all rats. Positive control group was administrated,ip;other rats were parenterally administrated. The blood glucose levels in groups were detected be-fore and after 15-600 min administration. Glucose tolerance test was conducted for the rats in normal control group,model group without glucose,model group with glucose and microemulsion group (Insulin self-microemulsion 9 u/kg). All group were given glucose except model group without glucose.RESULTS:
Compared with sham-operation group,the blood glucose levels in model group within 0-240 min were increased,with significant difference(P<0.05). Compared with model group,there was hypoglyce-mic trend in positive control group after 15 min,the blood glucose levels within 30-480 min were decreased,the hypoglycemic peak was 36%,and the peak time was 30 min;there was also hypoglycemic trend in microemulsion low,medium and high dose groups after 30 min,the blood glucose levels within 45-360 min were decreased,hypoglycemic peak was 18%-21%,and the peak time was 90-120 min,with significant differences (P<0.01 or P<0.05). All rats had glucose absorption peak except for model group without glucose in glucose tolerance test,and glucose of rats in microemulsion group reached its peak and then quickly de-creased.CONCLUSIONS:
Insulin self-microemulsion can obviously reduce the blood glucose of model rats with type 1 diabetes.
