Table 2. Histological parameters for assessment of wound healing score.

The histological numerical grading parameters used to calculate wound healing score. Number 1 to 4: H&E staining, Number 5 to 6: MT staining.

Number	Staining	Histologic parameters
1	H&E	Degree of granulation tissue (profound-1, moderate-2, scanty-3, absent-4)
2	H&E	Inflammatory infiltrate (plenty-1, moderate-2, few-3)
3	H&E	Orientation of collagen fibre (vertical-1, mixed-2, horizontal-3)
4	H&E	Pattern of collagen (reticular-1, mixed-2, fascicle-3)
5	MT	Amount of early collagen (profound-1, moderate-2, minimal-3, absent-4)
6	MT	Amount of mature collagen (profound-1, moderate-2, minimal-3)
