Purpose: The aim of this study was to investigate whether serum procalcitonin and creatine-phosphokinase levels may be useful parameters to indicate the severity of tissue damage and to seek a correlation between serum procalcitonin and creatine-phosphokinase levels and tissue histopathology. Material and Method: A total of 32 rats were divided into 4 groups, each consisting of 8 rats. Group 1 did not undergo any procedure and was assigned as the control group. Groups 2, 3, and 4 were exposed

Groups 2, 3, and 4 were named low voltage, moderate voltage, and high voltage groups, respectively. Electric injury was induced with a specifically adjusted high voltage test device. Rats were anesthetized and given electricity of 0.1 Amper for 5 seconds through electrodes connected to the right upper and lower extremities. Blood samples were drawn from the rats at the 12 th hour of the experiment to obtain serum procalcitonin and creatine-phosphokinase levels. Tissue samples were obtained from the striated muscle tissue from the right thigh and evaluated histopathologically using a light microscope. Results: Procalcitonin and creatine-phosphokinase levels in the samples taken after exposure to electricity were significantly higher in the high-voltage group than those in the control group (p<0.05). The histopathologic score results in the samples, which were taken after the electric exposure, were also significantly higher in high-voltage group than those in the control group (p<0.05). Conclusion: Serum procalcitonin and creatinin-phosphokinase levels may be useful indicators to estimate tissue damage in high-voltage electric injuries because serum procalcitonin and creatinin-phosphokinase levels were found to be significantly correlated with histopathologic damage score results. High-voltage appears to cause more severe tissue damage compared with low-and moderate-voltage because the histopathologic score results of the high-voltage group were significantly higher than those of the control group. Özet Amaç: Elektrik yaralanmalarýnda serum prokalsitonin ve kreatin kinaz deðerlerinin dokuda oluþan hasar düzeyini göstermede yararlý bir parametre olup olmadýðýný araþtýrmak ve elde edilen sonuçlarýn doku histopatolojisi ile uyumunun incelenmesidir. Gereç ve Yöntem: Çalýþma, her biri sekiz rat içeren dört grup ile deneysel olarak yapýldý. Çalýþmaya alýnan ratlarýn ilk sekiz tanesi sham grubu olarak seçildi ve yaralanma oluþturulmadý. Çalýþmadaki diðer rat gruplarýna 110, 220, 600 volt deðerlerinde elektrik akýmý beþ saniye süresince 0,1 amper deðerinde ve ratlarýn sað üst-alt ekstremitelerine baðlanan elektrotlar vasýtasýyla anestezi altýnda yüksek gerilim test cihazý kullanýlarak verildi. Çalýþmanýn 12. saatinde tüm gruplardan prokalsitonin ve kreatin kinaz düzeylerinin bakýlmasý amacýyla serum örnekleri ve doku histopatolojisi için sað uyluk bölgesindeki kas gruplarýndan biyopsi örnekleri alýndý. Biyopsi materyalleri hemotoksilen-eosin ile boyanarak ýþýk mikroskobunda deðerlendirildi. Bulgular: Elektrik yaralanmasýnýn oluþturulduðu üç gruptan yanýk sonrasý alýnan serum örneklerindeki kreatin kinaz ve prokalsitonin sonuçlarý incelendiðinde yüksek voltaj grubuna ait verilerin istatistiksel olarak anlamlý derece yüksek olduðu tespit edilmiþtir (p<0,05). Ayrýca elektrik yaralanmasý oluþturulan gruplardan elde edilen histopatolojik skorlama sonuçlarý kontrol grubu ile karþýlaþtýrýldýðýnda sonuçlar istatistiksel olarak anlamlý bulunmuþtur (p<0,05). Sonuç: Yüksek voltaj elektrik yaralanmalarýnda serum prokalsitonin ve kreatin kinaz düzeylerinin doku hasarýný göstermede faydalý birer parametre olduðu tespit edilmiþtir.
