|
Cyto-toxic effect of silver sulfadiazine (Ag-SD) on kerationcytes and its implication of wound healing process were investigated in 2^nd degree burn hairless mouse model. As a dermal model, HaCat (immortalized Keratinocytes) monolayer culture in DMEM with 10% FBS was used. Cyto-toxicity of Ag-SD was estimated by measuring the cell viability using neutral red assay after adding the drug. The 2^nd degree burn was prepared on hairless mouse back skin (1 cm diameter)and dressings with Ag-SD were applied for 96 hr. The process of re-epithelialization and the presence of inflammatory cells were investigated and histology with Hematoxylin-Eosin staining was performed. Ag-SD displayed highly cyto-toxic effect on cultured HaCat cells in a concentration dependent manner (1-100 ㎍/mL). Topical applicantion of Ag-SD(2%) could control the infection: no inflammatory cells were obsevered in histology. However the cyto-toxic effect of Ag-SD on skin cells induced the impairment in epidermal regeneration.
