Figure 1.

Methanol (Met) and hexane (Hex) extracts of Cucurbita argyrosperma seed in chemically burned corneas (CB) compared to the untreated group (CB corneas treated with the vehicle, CB-Veh). (a) Average of opacity score (OPA) and corneal neovascularization area (CNV) in mm². (b) Re-epithelialization percentage (RE). (c) Corneal thickness in microns (THK) and infiltration cell percentage (INF). Average value ± SD; * p < 0.05; ** p < 0.01, and ^α p < 0.001 compared to CB-Veh. ^@ p < 0.05 compared to CB-Met. Gray dotted lines show studied area, and black lines are the geometrical axis. CB-Hex: CB corneas treated with hexanic extract; CB-Met: CB corneas treated with methanolic extract. Arrows indicate the lumen of stromal blood vessels. (Scale bar = 100 μm).
