Cell viability of islets isolated from rats. After isolated islets were administered with vehicle (DMSO), 50 μg/ml extracts of Galla Rhois, Rehmanniae radix, M. bark, Ginseng radix, Polygonatum radix or Scutellariae radix, or 2.5 nM exendin-4 in high glucose DMEM media, cell viability was measured with a WST-1 assay kit at 6, 12 and 36 h. These experiments were repeated four times, and the results were expressed as mean ± SD. Asterisks are significantly different from the control (DMSO-treated) group in two-sample t-test at P < 0.05
