Molecular mechanisms of Buqing granule for the treatment of diabetic retinopathy: Network pharmacology analysis and experimental validation

Figure 7 Effects of Buqing granule on retinal morphology in diabetic retinopathy rats. A: Hematoxylin & eosin staining of the retina of rats in each group (400 ×); B: Retinal ganglion cell count in each group; C: Comparison of retinal thickness in each group. The sequence from left to right represents the control group, the model group, the Buqing granule group and the Calcium dobesilate group. ^aP < 0.05, ^bP < 0.01, ^cP < 0.001. BQKL: Buqing granule; CaD: Calcium dobesilate. GCL: Ganglion cell layer; IPL: Inner plexiform layer; INL: Inner nuclear layer; OPL: Outer plexiform layer; ONL: Outer nuclear layer.
