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

Figure 8 Immunohistochemical results of retinal tissue from different rat models. A: Immunohistochemical detection of Caspase-3; B: Immunohistochemical detection of c-Jun; C: Immunohistochemical detection of MAPK1; D: Immunohistochemical detection of MAPK3 positive expression (200 ×). 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.
