Glucose levels in the different groups. The letters a (p-value < 0.05), b (p-value <0.01) and c (p-value <0.001)) showing the significant of the different rat groups in comparison to the control (CN) group. The letters x (p-value < 0.05), y (p-value <0.01) and z (p-value <0.001)) indicate significant differences in the different rat groups in comparison to the diabetic (STZ-treated) group
