AIM: To observe the effects on four effective components of Qingguang'an on collagen fibers, α-smooth muscle actin(α-SMA)and fibronectin(FN)in rabbits after glaucoma surgery.<p>METHODS: Apply four kinds of effective components of Qingguang'an and Qingguang'an Chinese medicine suspension to D, E, F, G, H groups after filtration surgery, and pass with group A(blank control group)and group B(model group)Compared with group C(Mitomycin C group), the effects of four effective components of Qingguang'an and Qingguang'an traditional Chinese medicine suspension on collagen fibers, α-SMA and FN in the scar tissue of glaucoma after filtration were observed.<p>RESULTS: Compare to B group, the ratio of collagen fiber area to E, F, H group, the expressions of α-SMA and the expressions of FN were different(<i>P</i><0.05). <p>CONCLUSION: Qingguang'an effective components 2, Qingguang'an effective components 3, mitomycin C and Qingguang'an suspension reduce the proliferation of myofibroblasts and fibroblasts by inhibiting the expression of collagen fibers, α-SMA and FN, and showed obvious anti-glaucoma staining scar after surgery.
