Effect of Streptozocin on the Langerhans Islands in the pancreas of birds

In the current study, birds (Columba livia ) were used as a new model to study the effect of streptozotocin on the pancreas gland and the blood glucose level. Three concentrations of 75,65,55 mg/kg were adopted for five consecutive days with one IP dose daily. The experimental animals showed a gradual rise in blood glucose the average glucose in the first week of the experiment was usual for the three groups compared with the control group, while there was a significant change in the blood glucose level in the three groups at the end of the experiment (4th week), where the average glucose in the streptozotocin groups was 55 mg/kg (213.80 ± 12.43) mg/dl and the group 65 mg/kg(282.60 ± 16.78) mg/dl and a group of 75 mg/kg( 371.0 ± 38.39) mg/dl.
