Figure 4: STZ-induced diabetic rats were the highest amount of glucosuria, while healthy rats were approach zero of urine sugar. The effect of PLB treatment on the urinary glucose levels in STZ-induced diabetic rats (subdivided as high (H), moderate (M), and low (L) glucosuria subgroups). The rats received PLB treatment for 4 h/d over a 5-d period. Urine glucose levels were assessed immediately using an enzyme assay kit (Randox Laboratories, Antrim, UK). **p<.05 when compared with the control.
