Abstract

Background: electrocution in water had no specific mark. This phenomenon caused difficulties in proofing human deaths by electrical current for judge. This study was aimed to prove the difference of histopatologic presentation after electrical insult in fresh water between gastrocnemius muscle left upper limb and right upper limb on Wistar rats. Methods: This was a laboratory experimental study with post test only group design, using 24 wistar rats divided into 4 groups through simple random sampling. The first group (P1) received 1 – 30 mA of electrical current, the second (P2) received 31 – 60 mA, the third (P3) received 61 – 90 mA, and the last (P4) received 91 – 120 mA of electrical current. These currents were received through fresh water in 60 seconds. After electrocution in fresh water was performed then the decapitation of the rats in order to gain the gastrocnemius muscles of left upper limbs and right upper limbs. These muscles were made into histopatological specimens and the hypercontractions were counted. Statistical analysis was conducted by using the independent-t test each group. Result: Due to the analysist of the mean score there was no significant difference between left upper limbs and the right upper limbs in every group because p>=0,05 (p=0.234; p=0.819; p=0.496; and p=0.569 respectively). Conclusion: there is no different of histopatologic presentation after electrical insult in fresh water between gastrocnemius muscle left upper limb and right upper limb on Wistar rats. Keywords: electrical current, water conduction, gastrocnemius muscle, hypercontraction.
