Abstract
Latar Belakang: Luka bakar listrik menyebabkan cedera serius setiap tahun PADA 1.000 - 1500 orang di seluruh dunia dengan mortalitas 20-30% dan 74% korban selamat dengan cedera permanen dan sekuel. Tingkat nekrosis pada luka bakar seringkali sulit untuk ditentukan karena sirkulasi mikrovaskuler pada jaringan dalam terlibat. Beberapa penelitian menemukan bahwa N-acetylcysteine (NAC) sebagai sumber antioksidan oral dapat mengatasi stres oksidatif dan memiliki efek perlindungan terhadap kerusakan jaringan dari radikal bebas, secara hipotetis dengan sekresi berbagai faktor pertumbuhan yang mempercepat penyembuhan luka. Penelitian ini bertujuan untuk mempelajari pengaruh NAC terhadap tingkat faktor pertumbuhan endotermal vaskular (VEGF) dan faktor pertumbuhan fibroblast (FGF) dalam model luka bakar listrik tikus.Metode: Ini adalah desain pengujian kelompok hanya uji pasca acak. Empat puluh dua tikus galur Wistar jantan dirawat di enam kelompok. Setiap tikus diberikan arus bolak listrik sebesar 220 volt, 450-500 mA pada satu ekstremitas. Kelompok pertama hingga ketiga tidak menerima pengobatan dan arteri femoralisnya dipanen pada hari arus listrik di kelompok pertama, ketiga, dan delapan hari berturut-turut. Kelompok keempat hingga keenam menerima dosis harian 600 mg / kg secara oral. Arteri femoralis dipanen setelah dosis pertama NAC, setelah dosis hari ketiga, dan setelah delapan hari masing-masing dosis. Semua spesimen arteri femoralis bernoda imunohistokimia dan diperiksa untuk ekspresi VEGF dan FGF di bawah 300 kali mikroskop. Semua data dikumpulkan dan dianalisis secara statistik.Hasil: Kadar rata-rata VEGF kelompok tikus yang menerima NAC lebih tinggi daripada kelompok kontrol dari awal pengamatan sampai hari ke 8. Hasil FGF pada tikus kontrol lebih tinggi pada hari ke-0 dan hari ke-8 dibandingkan dengan kelompok tikus yang menerima NAC. Namun, dalam tes yang berbeda tidak ada perbedaan yang signifikan (p> 0,05) yang ditemukan pada pengukuran VEGF dan FGF pada hari yang sama antara kelompok kontrol dan kelompok perlakuan.Kesimpulan: Tidak ada perbedaan yang signifikan pada kedua tingkat VEGF dan FGF antara kelompok kontrol negatif dan kelompok perlakuan. Background: Electric burns cause serious injuries every year IN 1,000-1500 people worldwide with a mortality of 20-30% and 74% of survivors with permanent injuries and sequelae. The degree of necrosis in burns is often difficult to determine because the microvascular circulation of deep tissue is involved. Several studies have found that N-acetylcysteine (NAC) as a source of oral antioxidants can overcome oxidative stress and have a protective effect against tissue damage from free radicals, hypothetically by the secretion of various growth factors that promote wound healing. This study aims to study the effect of NAC on the levels of vascular endothermal growth factor (VEGF) and fibroblast growth factor (FGF) in a rat electric burn model.Method: This is a post-randomized only group testing design. Forty-two male Wistar rats were treated in six groups. Each mouse was given an alternating current of 220 volts, 450-500 mA on one limb. The first to third groups received no treatment and their femoral arteries were harvested on the electric current day in the first, third, and eight consecutive days. The fourth to sixth groups received a daily dose of 600 mg / kg orally. The femoral artery was harvested after the first dose of NAC, after the third day of dose, and after eight days of each dose. All femoral artery specimens were stained immunohistochemically and examined for VEGF and FGF expression the microscope with 300 magnification power. All data were collected and analysed statistically.Results: The mean VEGF level of the rats receiving NAC was higher than the control group from baseline to day 8. The FGF results in control mice were higher on day 0 and day 8 compared to the group of mice receiving NAC. However, in different tests no significant differences (p> 0.05) were found in the VEGF and FGF measurements on the same day between the control and treatment groups.Conclusion: There are no significant differences in both the VEGF and FGF levels between the negative control group and the treatment group.
