Figure 5From: Novel preparation of PLGA/HP55 nanoparticles for oral insulin deliveryPlasma glucose levels. After oral administration of the insulin-loaded PLGA/HP55 nanoparticles (50 IU/kg), blank nanoparticles, and SC injection of insulin solution (5.0 IU/kg) in diabetic rats (mean ± S.D., n = 3). Significant difference from blank nanoparticles control (p < 0.05).Back to article page
