Objective: This study aimed to ascertain the curative effects of Gamisipjeon-tang (GST) used for wound healing on the skin regeneration of deep second degree burns in mice.
Material & Methods: In vitro, the kinase (IKK) mRNA expression, inducible nitric oxide synthase (iNOS) mRNA expression, and cyclooxygenase-2 (COX-2) mRNA expression in the GST concentration from 1 mg/ to 10 mg/ were measured. In vivo, the mice were divided into four groups : the normal group, the BE group (burn-elicited group, control group), the DC group (Duoderm CGF-treated group after burn elicitation), and the GST group (Gamisipjeon-tang treated group after burn elicitation). To determine the anti-inflammatory effects, nuclear factor (NF)- p65, iNOS, COX-2 positive reaction were measured by immunohistochemistry. To estimate the skin regenerative effects, change of burn area, 5-bromo-2’-deoxyuridine (BrdU), and fibroblast growth factor (FGF) positive reaction were analyzed.
Results: In vitro, the iNOS, IKK, COX-2 mRNA expression decreased according to the increase of GST concentration. The significant decrease of COX-2, iNOS, NF- positive reaction were the highest in the GST group, followed by the DC group and the BE group (p<0.05). The diameter of burn area was significantly decreased in the GST group as compared to that in the DC and BE group (p<0.05). The BrdU and FGF positive reaction increased more significantly in the GST group than in the DC group, and more significantly in the DC group than in the BE group on the 3rd and 7th day after burn (p<0.05). FGF positive reaction increased in the BE and DC group, whereas it decreased significantly in the GST group on the 14th day (p<0.05). The BrdU positive reaction increased in the BE group, whereas it decreased significantly in the DC and GST group on the 14th day (p<0.05).
Conclusions: This study shows that GST could decrease the inflammatory response and accelerate the skin regeneration as compared to the duoderm CGF in mice with deep second degree burns.
