The values in each group are represented as Means ± Standard deviation. Significant p values (p<0.05) of both C-peptide and serum glucose were detected between (٭) and (٭٭), however, insignificant p values (p>0.05) of C-peptide were displayed between (G1#) and (G2##). Group I (control or nondiabetic fed on ordinary lab diet); Group II (non-diabetic fed on fatty diet); Group III (diabetic fed on ordinary lab diet); Group IV (diabetic fed on fatty diet); Day 0 = The first day after fat feeding following induction of diabetes by injecting streptozotocin. Normal serum C-peptide was 0.5-3.0 ng/ml, serum glucose was 120-140 mg/dl.
