Histopathological score of burn wounds in different treatments

Histological differences seen on H&E-stained sections	Burn alone	Solosite	Low AB569	High AB569	PA + high AB569
Acute polymorphonuclear leukocyte inflammation (score 0–4 per wound); 0 = no inflammation; 1 = minimal inflammation; 2 = mild; 3 = moderate; 4 = marked inflammation	4	4	2	3	3
Fibroblasts and capillary proliferation (score 0–3 per wound); 0 = no fibroblasts and blood vessels/capillaries; 1 = few fibroblasts with few capillaries; 2 = intermediate presence of fibroblasts and presence of capillaries; 3 = mature fibroblasts and several blood vessels	1	2	3	2	3
Amt of collagen deposition between fibroblasts (score 0–4 per wound); 0 = normal large amt; 1 = marked; 2 = moderate; 3 = mild; 4 = minimal amt	1	1	4	2	1
Total scoring of the wounds (a higher score signifies better healing outcome)	6	7	9	7	7
