Abstract: Postmortem changes play an important role in estimation of the time of death. This study was aimed to obtain the histopathological changes of lungs at several time intervals postmortem. This was a descriptive observational study using a local pig as the animal model killed by stabbing in the heart. Lung samples were taken at 15 minutes, 30 minutes, 45 minutes, 60 minutes, 75 minutes, 90 minutes, 2 hours, 3 hours, 4 hours, 5 hours, 6 hours, 12 hours, and 24 hours postmortem. The results showed that the earliest histological change could be identified at 60 minutes postmortem in the form of alveolar dilatation. At 2 hours postmortem, congestion of smooth muscle layers of bronchioles was observed. The epithelial cells of the alveoli were undetected at 3 hours postmortem meanwhile the smooth muscle layers were undetected at 12 hours postmortem. At 24 hours postmortem, the bronchioles were still detected but the structure of their layers could not be identified. Conclusion: Histopathological changes were observed as alveolar dilatation at 60 minutes postmortem, followed by congestion of muscle layers, and undetected epithelial alveolar cells as well as smooth muscle layers. At 24 hours postmortem, bronchioles were still detected but the structure of their layers could not be identified.Keywords: histological changes, lungs, postmorterm Abstrak: Perubahan postmortem berperan penting untuk memperkirakan waktu kematian.

Abstract: Commonly, unnatural death is complicated and causes difficulties for to the investigating officers to reveal the modus operandi and the time of death. Estimation of postmortem interval is very important in the investigation, albeit, it is frequently put the investigators to a debate. This study aimed to obtain the histological changes of heart muscle at several time intervals postmortem. This was a descriptive observational study. A domestic pig weighed ±20kg was used as model. The pig was killled by conducting a blunt trauma at its occipital area. Heart muscle samples were taken at several time intervals as follows: 15 minutes, 30 minutes, 45 minutes, 60 minutes, 75 minutes, 90 minutes, 105 minutes, 2 hours, 3 hours, 4 hours, 5 hours, 6 hours, 12 hours, and 24 hours postmortem. The histological changes were observed with an Olympus CX21 microscope and Optilab. The percentages of those changes were evaluated at 5 high-power fields (400x) for each sample. The results showed that less than 30% of myocytes had flattened and denser nuclei at 105 minutes postmortem and were associated with hydrophic degeneration at 2 hours postmortem. Those changes became widely spreaded and at 24 hours postmortem they could be identified in 60-80% of myocytes. Albeit, the striated pattern could still be identified until 24 hours postmortem. Conclusion: The histological changes of heart muscle postmortem namely morpholocical changes of the nuclei and hydrophic degeneration could be identified at 2 hours postmortem. At 24 hours postmortem those changes were distributed widely among the myocytes, however, the striated pattern could still be identified. Moreover, there were still focal areas with normal appearance. Keywords: histological changes, cardiac muscle, postmortem Abstrak: Kematian tidak wajar yang dialami seseorang dengan berbagai motif kejahatan dapat menyulitkan para penyidik dalam menggungkapkan modus operandi dan waktu kematian.

Abstract: Studies about postmortem histological changes in stomach is still very limited. This study aimed to obtain histological changes of stomach in several time intervals during 24 hours postmortem. This is a descriptive study using pig as model. Samples of fundus tissue taken in several time intervals in postmortem were as follows: 0 hour, 1 hour, 2 hours, 3 hours, 4 hours, 5 hours, 6 hours, 7 hours, 8 hours, 9 hours, 12 hours, 14 hours, 16 hours, 18 hours, 20 hours, 22 hours, and 24 hours. The results showed that the earliest histological change was identified at 2 hours postmortem as fundic gland cell congestion. At 7 hours postmortem the contours of some fundic glands and borders of their cells were not distinct anymore, meanwhile their nuclei were dispersed among the remnants of fundic glands. At 18-24 hours postmortem, almost all fundic glands could not be indetified. Conclusion: The earliest histological change of stomach was identified at 2 hours postmortem as fundic gland cell congestion, followed by necrosis of fundic gland cells since 7 hours postmortem.Keywords: postmortem histological changes, fundic glands, postmortem interval Abstrak: Studi mengenai perubahan gambaran histologik gaster postmortem masih sangat terbatas.

Abstract: Estimation of postmortem interval plays some significant roles in medicolegal investigation. This was a descriptive experimental study using one local pig as model. Samples were taken from the right and left kidneys at several time intervals: 0 minute, 15 minutes, 30 minutes, 45 minutes, 60 minutes, 12 hours, and 24 hours postmortem. The results showed several histological changes, as follows: hydrophic degeneration in a small part of proximal tubules 30 minutes postmortem that increased after 45 minutes associated with narrowing of Bowman cavities; necrosis of glomeruli and proximal tubules associated with irregular distal tubular lumen and widening of Bowman cavities 60 minutes postmortem; necrosis of distal tubuli 12 hours postmortem; and necrosis of most kidney structures 24 hours postmortem. Conclusion: Hydrophic degeneration of proximal tubuli is the earliest histological change 30 minutes postmortem, followed by necrosis of glomeruli as well as proximal and distal tubuli that worsened after 24 hours postmortem. It is expected that this study can provide valuable contribution to medicolegal investigation, especially in early postmortem interval estimation.Keywords: postmortem interval, histological changes, postmortem, kidneyAbstrak: Penentuan saat kematian sangat penting dalam penyelidikan medikolegal. Penelitian ini merupakan penelitian deskriptif-eksperimental dengan menggunakan satu ekor babi lokal sebagai obyek penelitian. Sampel diambil dari ginjal kanan dan kiri pada beberapa interval waktu; 0 menit; 15 menit; 30 menit; 45 menit; 60 menit; 12 jam; dan 24 jam postmortem. Hasil penelitian memperlihatkan degenerasi hidropik pada sebagian kecil tubuli proksimal 30 menit postmortem yang meluas setelah 45 menit disertai penyempitan kavum Bowman; pelebaran kavum Bowman, nekrosis glomeruli dan tubuli proksimal, lumen sebagian kecil tubuli distal ireguler 60 menit postmortem; nekrosis tubuli distal 12 jam postmortem; dan nekrosis hampir seluruh struktur-struktur tersebut 24 jam postmortem. Simpulan: Degenerasi hidropik tubuli proksimal merupakan perubahan histologik yang paling dini yaitu 30 menit postmortem, disusul oleh tanda-tanda nekrosis pada sebagian kecil glomeruli dan tubuli proksimal serta nekrosis tubuli distal yang meluas setelah 24 jam postmortem. Penelitian ini diharapkan dapat memberikan kontribusi yang bermakna untuk kepentingan medikolegal, terutama dalam perkiraan saat kematian dini.Kata kunci: saat kematian, perubahan histologik, ginjal

The adenocarcinomas of the intestine induced in Syrian hamsters by N-methyl-N-nitrosourea (NMU) were of two histological types, superficial and intestinal. These types had distinctive characteristics regarding pattern, cytological features, secretion of mucus, and mode of growth. The histological changes induced by NMU in the mucosa of the small intestine differed from what has been described in enzootic intestinal adenocarcinoma and proliferative ileitis of Syrian hamsters. NMU produced alteration in the villous architecture and cytological change in the absorptive cells. There was marked shortening of the villi and reduced thickness of the mucosa. The villous absorptive cells were large and cuboidal with centrally placed nuclei.

Objective: This study aimed to determine a target of action of bruceine A on the basis of its morphological and histological effects on the larvae of Aedes aegypti Linnaeus.Methods: Bruceine A was isolated from Brucea javanica (L.) Merr. seeds in accordance with the Mangungsong method. Larvae of A. Aegypti (L.) in instar III to the beginning of instar IV were treated with various concentrations of bruceine A. The negative control group did not receive any treatment, whereas the positive control group received 1 ppm temefos. Dead larvae were collected after 24 h of treatment for the examination of morphological and histological changes.Results: The negative control group did not exhibit any morphological and histological changes. Larvae treated with bruceine A, however, had visible damaged heads, cuticles, digestive and respiration tracts, respiratory siphons, and setae, and they were smaller than normal larvae. Larvae treated with temefos exhibited gastrointestinal damage, narrowed breathing tubes, cuticle damage, and detached/damaged seta feathers. The necrosis of gastrointestinal epithelial cells was the major histological change exhibited by larvae treated with various concentrations of bruceine A or 1 ppm temefos.Conclusion: The targets of action of bruceine A in A. aegypti (L.) larvae are the head/caput, cuticle, setae, siphon, and gastrointestinal and respiratory tracts.
