Note: control is diabetic rats without PLB treatment; H, M, and L groups are high, moderate, and low glucosuria of diabetic rates, respectively with PLB treatment; health group is healthy rats. Observation is number of measured urine glucose from two rats in each group within 10 weeks of experimental period. P-value < 0.05 means significant difference of comparison of two groups.
