When insufficient donor sites are present or patients are afraid of the operation, a skin graft is impossible. Cultured allogenic keratinocytes speed wound healing by providing cover and by producing growth factors and extracellular matrix protein. We report an application of cultured allogenic keratinocytes (Kaloderm, Tegoscience, Seoul, Korea) in the treatment of an acute partial thickness skin defect. Methods: From March 2005 to January 2006, 20 patients with a partial thickness skin defect were treated with cultured allogenic keratinocytes. The wound was covered with a sheet of cultured allogenic keratinocytes and ointment with Bactigras gauze. The wound was inspected every two or three days. We regarded completion of epithelialization as wound healing. Results: The mean period between time of injury and time of Kaloderm application was 7.5 days. The time taken from application of Kaloderm to complete closure of the wounds was 7.2 days. Conclusion: In view of the favorable outcome, cultured allogenic keratinocytes are safe and effective biologic dressing materials for use in the treatment of open wounds.

Ⅲ. 결과환자들의평균연령은 20.3세 (1개월 ~69세 ) 였으며, 그중남자가 10명, 여자가 10명이었다. 수상후동종유래각질세포를적용할때까지의기간은평균 7.5±7.7일 (0일 ~23일 ) 이었으며, 동종유래각질세포적용후창상치유가완료될때까지걸린기간은평균 7.2±2.4일 (4일 ~14일 ) 이었다. 수상후부터창상치유완료까지걸린기간은평균 14.6±8.9 일 (5일 ~31일 ) 이었다. 총 20명의환자들중 17명은동종유래각질세포 1회적용에창상치유가완료되었다. 생후 21 개월남자환아 (Patient No. 4) 와 19개월여자환아 (Patient No. 12) 가수부에발생한심부 2도화상으로동종유래각질세포 2 회적용후에창상치유가완료되었으며, 수상후 창상치유까지는각각 20일과 11일이소요되었다. 또한 31 세여자환자 (Patient No. 15) 가칼에의한수지의피부결손으로내원하여동종유래각질세포 2 회적용후에창상치유가완료되었으며, 소요기간은 29일이었다 (Table 1)(Fig. 1-3). Ⅳ. 고찰창상에대한소독방법은개방소독, 폐쇄소독, 습윤환경소독, 생물학적소독등이있다. 최근창상처치의목표로는창상치유촉진, 통증감소, 피부보호기능의회복, 미용적으로만족할만한결과, 더욱깊은손상으로의진행방지등을들수있으며, 이러한목표에가장부합하는것으로는생물학적소독을들수있다.(1) 생물학적소독재료의종류에는사체피부, 양막등의동종이식과돼지, 개의피부, 소의양막과같은이종피부등이있고, 인공제작된 Kaloderm, Biobrane (Bertek Pharmaceuticals Inc., Morgan town, WV) TransCyte (Advanced Tissue Sciences, La Jolla, CA) 등이있다.(2) 동종이식또는이종피부등은항원성 (antigenicity) 이있으며, 내인성 (durability), 무균성 (sterility) 의결여와항상사용할수없다는점에서임상적사용에제한이있다.(3) 따라서최근에는인공제작된생물학적소독재료를많이사용하는추세다. 1975년 Rheinwald와 Green이각질세포배양기술을발 A B C D Fig. 3.

5 서상원외 : 동종유래각질세포를이용한피부결손치료 전시킨이후광범위화상환자의치료에적용되었으며, 1983년동종유래각질세포가광범위화상환자의피부대용물로사용되기시작하였다.(4) 다른동종장기이식 (solid-organ allograft) 과는달리동종유래각질세포는 passenger leukocyte를포함하지않으며, MHC class II 항원 (antigen) 을표현하지않는다. 그러나생체내에서는 interferon-γ와여러가지사이토카인등이존재하여결국면역학적활성을가지게된다.(4,5) 따라서동종유래각질세포는급성면역반응은없으나궁극적으로는거부되거나숙주 (host) 의각질세포로대체되게된다. 동종유래각질세포를화상이나부분층피부이식공여부창상에적용할경우창상치유가촉진된다는보고가있다.(6) 동종유래각질세포는 GM-CSF, TGF-β1, TGF-α, β FGF, VEGF, IL-1α, IL-8 등의성장인자를분비하며, 상피의부착과이동에관여하는 fibronectin, laminin, thrombospondin, 세포외기질단백질 (extracellular matrix proteins) 등을합성및분비하여창상치유를촉진한다.(6) 따라서, 창상부위의가장자리에서창상중심부위를향해이동하는각질세포와창상부의모근 (hair follicle) 등에일부남아있는각질세포들이동종유래각질세포와접촉 (contact) 함으로써보다더빠르게상피화를할수있다. 실제로각질세포 (keratinocyte) 는표피의주요세포로서외부의자극을받으면여러가지사이토카인 (cytokine) 을분비하며, 화학주성수용체 (chemokine receptors) 를가지고있다.(7) 특히각질세포에서분비하는 GM-CSF, TGFβ1, TGF-α등은창상치유를촉진시키는것으로알려져있다.(7,8) 이상적인생물학적소독재료는부착성 (adherence), 세균증식억제, 수분및전해질손실방지, 내인성 (durability), 저장성 (availability), 안정성, 경제성, 지혈성 (hemostatic) 및사용의간편성등의특성을가져야한다.(8) 동종유래각질세포는미리준비되어있어필요시즉시사용할수있으며, 화상환자에서는면역기능의저하로이식물이장기간생착가능하며, 각종성장인자등의분비로재상피화를촉진시킨다는장점이있다. 또한통증이적고잦은소독재료의교환이필요없어특히소아의경우에적용할만하다.(9) 그러나가격이비싸며, 감염에약하다는단점이있다. 저자들의경우동종유래각질세포를이 용하여다양한부위와다양한손상정도의병변을치료하였으나대조군이없어객관적인결과를알기힘든한계가있었다. Ⅴ. 결론 동종유래각질세포는고가이며감염에약한단점에도불구하고, 창상치유를촉진하며쉽게적용가능하고, 필요한양을필요한시기에사용할수있어부분층창상을가진환자의보존적치료에도움을줄수있어보고하는바이다.
