['To study the effect of matrix metalloproteinases inhibitor GM6001 in suppressing scar tissue formation in the filtering passage after glaucoma filtration surgery.', 'Twenty-four pigmented rabbits (48 eyes) underwent trabeculectomy followed by subconjunctival injection of GM6001 in the right eye (treated eyes) and injection of PBS in the left eye (control) once a day. The intraocular pressure was monitored postoperatively and proliferating cell nuclear antigen (PCNA)- and α-smooth muscle actin (α-SMA)-positive cells in the filtering pathway were detected using immunohistochemistry.', 'On postoperative days 7, 14, 21, and 28, the intraocular pressure was significantly lower in the treated eyes (GM6001) than in the control eyes (P<0.01). The counts of PCNA- and α-SMA-positive cells were also significantly lowered in the treated than in the control eyes (P<0.01).'] Does [ GM6001 suppress scar formation after glaucoma filtration surgery in rabbits ]?
