a Effect of VCN-2 hydrocolloid film which was topically applied on normal and diabetic rats inflicted with excision wound for 14 days. Production of pro-inflammatory cytokines such as IL-1β, IL-6 and TNF-α after different concentration of VCN-2 treatments. b Secretions of growth factors like VEGF and TGF-1β on day 14 with treatment of VCN-2 in concentration 12.5, 25, 50 μM. All values are expressed as mean ± SEM. Each group consists of six rats. ### p < 0.001, diabetic group compared to normal group; ***p < 0.001, treatments groups compared to diabetic group
