    Abstract
    Background: The granulocyte-macrophage colony stimulating factor is a multipotent growth factor that plays an important role in wound healing process. It is a group of cytokines that play a role in the regulation of proliferation, and differentiation of various cell communication in order to have the capacity and specialized functions, GM-CSF is responsible for the proliferation of granulocytes and macrophages that initiate the wound healing process. Objective: The purpose of this study was to see the effect of rhGM-CSF perilesion subcutaneously on artificial wounds in order to accelerate the speed of wound healing by comparison dexamethason and control groups. Methods: Mice (Mus musculus) with artificial wounds full thickness divided into 3 groups: A (n = 4) received rhGM-CSF 10μg/kg, B (n = 4) received dexamethason 10 mg / kg and C (n = 5) as control. Recombinant GM-CSF and dexamethason given for 6 days, and at day 7 all these animal euthanized. Wounds excised at 4 mm from the edge of the wound was then performed for histologic examination and calculation neovascular and keratinocytes. Results: The data obtained showed a positive effect of rhGM-CSF on the growth neovascular and keratinocytes (p = 0.001) than dexamethason and control. Not obtained significant differences between dexamethason and control groups in growth of keratinocytes (p = 0.085) and neovascular (p = 0.935). Conclusion: There is growth of keratinocytes and neovascular more tangible after the injection of rhGM-CSF compared to post-injection dexamethason and control and found no difference in the growth of keratinocytes and neovascular on dexamethason and control groups.
     
    Latar belakang : Granulocyte-macrophage colony stimulating factor adalah faktor pertumbuhan multipoten yang memainkan peranan penting dalam proses penyembuhan luka. Merupakan kelompok sitokin yang berperan dalam regulasi proliferasi, komunikasi dan diferensiasi berbagai sel agar mempunyai kapasitas dan fungsi terspesialisasi, GM-CSF bertanggung jawab atas proliferasi granulosit dan makrofag yang mengawali proses penyembuhan luka. Objektif : Tujuan dari penelitian ini adalah untuk melihat pengaruh pemberian rhGM-CSF perilesi pada luka artifisial guna mengakselerasi kecepatan penyembuhan luka dengan pembanding dexamethason dan kelompok kontrol. Metode : Mencit (Mus musculus) dengan luka artifisial full thickness dibagi dalam 3 kelompok: A (n=4) menerima rhGM-CSF 10µg/kg, B (n=4) menerima dexamethason 10 mg/kg dan C (n=5) sebagai kontrol. Rekombinan GM-CSF dan dexamethason diberikan selama 6 hari,dan pada hari ke 7 kesemua hewan coba dieuthanasia. Luka dieksisi pada batas 4 mm dari pinggir luka kemudian dilakukan pemeriksaan histologis untuk perhitungan keratinosit dan neovaskular. Hasil : Data yang didapat menunjukkan hasil pengaruh positif pemberian rhGM-CSF peri lesi subkutan terhadap pertumbuhan keratinosit dan neovaskular (p=0.001) dibanding dexamethason dan kontrol. Tidak didapat perbedaan signifikan antara kelompok dexamethason dan kontrol dalam pertumbuhan keratinosit (p=0,085) serta pertumbuhan neovaskular (p=0,935). Kesimpulan : Terdapat pertumbuhan keratinosit dan neovaskular yang lebih nyata pasca penyuntikan rhGM-CSF dibanding pasca penyuntikan dexamethason dan kontrol serta tidak dijumpai perbedaan pertumbuhan keratinosit dan neovaskular pada kelompok dexamethason dan kontrol.
