Table 1. Histology Scoring.

	Host Response	Score
Inflammation	0–4 PMNs/HPF	1
	5–20 PMNs/HPF	2
	>20 PMNs/HPF	3
	Diffuse band-like infiltrate (diffuse to numerous to count)	4
Depth of Inflammation	Inflammatory cells not present	1
	Inflammatory cells present within one-third of tissue matrix	2
	Inflammatory cells present within two-third of tissue matrix	3
	Inflammatory cells present within entire tissue matrix (full-thickness)	4
Neo-Vascularization	No or rare capillaries	1
	Few capillaries (<5 capillaries/HPF)	2
	Many capillaries (5–10 capillaries/HPF)	3
	Abundant capillaries present (granulation tissue)	4
Cellular re-population	Tissue matrix containing no nuclei of fibroblasts	1
	Tissue matrix containing nuclei of fibroblasts within one-third of matrix	2
	Tissue matrix containing nuclei of fibroblasts within two-third of matrix	3
	Tissue matrix containing nuclei of fibroblasts within full thickness of matrix	4

PMNs, polymorphonuclear cells; HPF, high power field;

*Cellular re-population of the acellular collagenous matrix by cellular collagen containing nuclei of fibroblast.
