Purpose: Numerous studies have investigated the pattern of traumatic death with a focus on the injury mechanism, the severity of the injury and the presence of hemorrhage. Acute coagulopathy has been treated as only one of many complications. The purpose of this study was to investigate the influence of acute coagulopathy on acute and early death due to trauma. Methods: A retrospective analysis of trauma patients with injury severity score (ISS)≥25 who had been treated between January 2011 and December 2012 was conducted. Based on the time of injury, traumatic death was categorized into acute (within 48 hours) and early (from 3 to 7 days). The correlations between various parameters within 24 hours after injury and time of death were analyzed. Results: A total of 124 patients were enrolled. Of them, 8.1% (n=10) of the patients experienced acute mortality. For those patients, significant differences in initial systolic blood pressure, coagulopathy score, amount of transfusion, abbreviated injury scale of the head and neck, the abdomen and the extremities were noted. Early mortality was experienced by 7.0% (n=8) of the patients, only coagulopathy score was found to be a significant independent risk factor for acute (odds ratio: 3.127; 95% confidence interval: 1.185-8.252; p=0.021) and early mortality (odds ratio: 2.470; 95% confidence interval: 1.029-5.929; p=0.043). Conclusion: Acute traumatic coagulopathy has an important role in the mortality, even after the acute phase. Early management and prevention of acute coagulopathy may improve survival of trauma patients. [ J Trauma Inj 2014; 27: 158-64 ]

섬유아세포에서 프로모터 다형성에 의한 Matrix Metalloproteinase-1의 발현에 관한 연구
이진우,정유정,봉심규,박노준,이상헌,노민수,임경민,김수남,Lee, Jin Woo,Jung, Yujung,Bong, Sim-Kyu,Park, No-June,Lee, Sang Heon,Noh, Minsoo,Lim, Kyung-Min,Kim, Su-Nam 대한화장품학회 2021 대한화장품학회지 Vol.47 No.3
본 연구는 피부 섬유아세포에 자외선을 조사하거나 TNF-α를 처리하면 세포에 따라 MMP-1의 발현이 다르게 나타나는데, 이것이 MMP-1 프로모터의 다형성에 의해서 나타남을 밝히기 위해 수행되었다. 시판하는 23 종의 primary 섬유아세포에 대하여 MMP-1 프로모터의 -1607 부위의 유전형을 분석한 결과 6 개의 1G/1G 유전형, 10 개의 1G/2G 유전형, 7 개의 2G/2G 유전형을 가진 섬유아세포를 확인할 수 있었다. Hs68과 Detroit 551 세포주는 1G/2G 유전형을 가지는 것으로 확인되었다. 1G/1G 유전형은 TNF-α 처리에 의해 대조군에 비해 MMP-1이 2 배 높게 발현되었으며, 자외선에 의해서는 거의 발현되지 않았다. 1G/2G 유전형의 경우는 TNF-α 처리에 의해 MMP-1이 2.45 배 높게 발현되었으며, 자외선에 의해서는 1.4 배 MMP-1이 발현되었다. 2G/2G 유전형의 경우는 TNF-α 처리에 의해 MMP-1이 1.35 배 발현되었으며, 자외선에 의해서는 2.5 배로 높게 발현되었다. 즉 1G 유전형은 TNF-α에 의해, 2G 유전형은 자외선에 의해 발현이 유도되는 것으로 추정할 수 있으며, -1607 위치에 하나 더 삽입된 G에 의해서 Ets 전사인자가 결합할 수 있는 site가 만들어져서 MMP-1의 발현이 증가한다고 추정할 수 있으며, 피부 노화와 관련하여 섬유아세포에서는 이에 대한 연구가 전혀 진행되어 있지 않아서 향후 추가로 연구되어야 할 부분이다. 피부는 내인성 노화와 광노화의 영향을 동시에 받는 기관이므로, 피부 노화를 개선하기 위한 타겟으로 MMP-1의 발현을 분석할 경우에는 실험 조건에 적합한 유전형을 가지는 세포를 선택하여 연구를 진행하는 전략을 세워야 할 필요성이 대두된다. The skin fibroblasts of different origins showed different expression levels of MMP-1 in response to TNF-α treatment or UV irradiation. We hypothesized that this is caused by polymorphism in the MMP-1 promoter region. To elucidate it, first of all, we analyzed and classified the genotype of the -1607 site of the MMP-1 promoter in 23 commercially available primary fibroblasts, and then we examined the expression of MMP-1 by TNF-α or UVB stimulation for each classified genotype. As a result of the analysis, fibroblasts with 6 1G/1G genotypes, 10 1G/2G genotypes, and 7 2G/2G genotypes were identified. Hs68 and Detroit 551 cell lines were confirmed to have 1G/2G genotypes. In the 1G/1G genotype, MMP-1 was expressed twice as high as that of the control group by TNF-α treatment, and was hardly expressed by UV light. In the case of the 1G/2G genotype, MMP-1 was expressed 2.45 fold higher by TNF-α treatment, and 1.4 fold by UV light than the control. In the case of the 2G/2G genotype, MMP-1 was expressed 1.35 fold by TNF-α treatment, and was highly expressed by 2.5 fold by ultraviolet rays compared to control. It can be estimated that MMP-1 expression is better induced in the 1G genotype by TNF-α and in the 2G genotype by UV light. In addition, it can be presumed that MMP-1 expression is increased by creating a site where the Ets transcription factor can bind by another G inserted at the -1607 position. These studies have not been conducted at all in fibroblasts in relation to skin aging, so it is an area that needs to be further studied in the future. In conclusion, since the skin is an organ that is affected by both intrinsic aging and photoaging at the same time, when analyzing the expression of MMP-1 as a target for improving skin aging, it is necessary to select cells with a genotype suitable for the experimental conditions of the study.

Anti-inflammatory and analgesic activities and skin irritation of piroxicam patch were investigated. Piroxicam patch increased the pain threshold in rat hind paw inflamed by carrageenan and inhibited writhing induced by acetic acid in mice. Piroxicam patch also inhibited the carrageenan-induced edema in rat hind paw as well as the increased vascular permeability induced by histamine in rats. In adjuvant arthritis of rats, piroxicam patch showed anti-inflammatory effects. Skin irritation of piroxicam patch was tested in Newzealand White rabbits and evaluated by Primary Irritation Index of Draize. The results from skin irritation test showed that piroxicam patch seemed practically non-irritating. The result from the present study indicates that piroxicam may be useful without serious side effects as anti-inflammatory analgesics in this patch form.
