Abstract

Background: Electrocution sometimes had no specific mark. This phenomenon caused difficulties in looking for the correct evidences of human deaths by electrical current. Electrocution tend to had only musle damage. Direct electrical insult often made hipercontraction in musles. This study was aimed to prove the differences of histopatologic presentation after direct electrical insult between gastrocnemius muscles point of contact and contralateral limb on wistar rats. Methods: 24 rats divided into 4 groups with simple random sampling. The four test groups got the electrical insult ((P1) 1 – 30 mA, (P2) 31 – 60 mA, (P3) 61 – 90 mA and (P4) 91 – 120 mA). The electrocution was done in 60 seconds then decapitation, sample collection and making speciments were performed and counted the hipercontraction afterward. Statistical analysist was conducted by using the independent sample-T test.. Result: The difference was significant if p<0,05. These were the mean scores of every left and right limbs of the groups (110,17±55,45 and 51,00±28,69 (p=0,017); 126,16±29,87 and 97,67±36,62 (p=0,183); 207,33±74,99 and 134,00±32 (p=0,052); and 374,67±120,03 and 217,50±68,54 (p= 0,019) respectively). Due to analysist of the mean score there were two significant differences between point of contact and contralateral limb on P1 (p = 0,017), and P4 (p = 0,019). Conclusion: There is different effect on histopatologic presentation after direct electrical insult between gastocnemius muscle point of contact and contralateral limb on Wistar rats. Keywords: electrical current, direct insult, gastrocnemius muscle, hypercontraction, electrocution.
