Latar Belakang : Asfiksia merupakan salah satu mekanisme kematian yang dapat terjadi akibat gantung. Otak merupakan salah satu organ penting yang dinilai dalam otopsi kasus gantung. Secara makroskopis tidaklah mudah membedakan temuan asfiksia pada otak yang terjadi antemortem dan perimortem. Adanya temuan asfiksia pada pemeriksaan mikrokopis dapat menentukan intravitalitas gantung. Penelitian ini bertujuan untuk mengetahui penentuan intravitalitas gantung berdasarkan gambaran histopatologis otakbesar mencit Balb/c.
Metode : Penelitian eksperimental ini menggunakan post test only with control group design yang telah memenuhi kelayakan etik dengan sampel berjumlah 18 mencit Balb/c jantan yang dibagi menjadi tiga kelompok yaitu kelompok kontrol yang tidak diberi perlakuan, kelompok antemortem yang digantung saat masih hidup, kelompok perimortem yang digantung 15 menit setelah mati. Pada kelompok pelakuan mencit digantung selama 1 jam dengan tali yang ditambahkan beban 50 gram. Penilaian gambaran histopatologi otak besar berdasarkan reaksi inflamasi dan perdarahan.
Hasil : Pada kelompok kontrol hampir tidak terdapat inflamasi dan perdarahan, pada kelompok antemortem terdapat inflamasi sedang hingga berat dan perdarahan berat, pada kelompok perimortem terdapat inflamasi dan perdarahan ringan hingga sedang. Pada uji Kruskal Wallis didapatkan perbedaan bermakna pada semua kelompok (p<0,05). Pada Uji Man Whitney didapatkan perbedaan yang bermakna pada parameter inflamasi dan perdarahan antara kelompok kontrol dengan kelompok antemortem dan perimortem, antara kelompok antemortem dan perimortem (p<0,05).
Simpulan : Intravitalitas Gantung dapat ditentukan berdasarkan gambaran histopatologis otak besar mencit Balb/c dimana reaksi inflamasi dan perdarahan berat didapatkan pada kelompok antemortem.

Hanging Intravitality Determination based on Cerebrum Histopathological Features in Balb/c Mice
Abstract
Background: Asphyxia is one of the death mechanisms that can occur due to hanging. The brain is one of the important organs autopsied in a hanging-related death case. Macroscopically, it is challenging to distinguish between asphyxiated brains occuring antemortem and those occurring perimortem. The presence of asphyxia on micro-examination can help determining the hanging intravitality. This study aims to determine hanging intravitality based on cereberum histopathological features in mice Balb/c mice.
Method: This is a post test only experimental study with control group examining 18 male Balb/c mice in three groups involving untreated control group, antemortem group hanged during alive, perimortem group hanged 15 minutes after death. In the treatment groups, mice were hanged with 50 grams load for 1 hour. Determination of histopathological features is based on inflammatory and bleeding reactions.
Results: Nearly no inflammation and bleeding was found in the control group, moderate to severe inflammation and heavy bleeding was found in the antemortem group, mild to moderate inflammation and bleeding was found in the perimortem group. The Kruskal Wallis test showed significant differences in all groups (p <0.05). The Man Whitney test found significant differences in the inflammatory and bleeding parameters between the control group and the antemortem and perimortem groups; between the antemortem and perimortem groups (p <0.05).
Conclusion: The cerebrum histopathological features of the Balb/c mice can indicate hanging intravitality in which the antemortem group shows inflammatory reactions and heavy bleeding.
