We studied four patients with muscle necrosis associated with acute renal failure to evaluate the diagnostic value of the bone scan in this disease. The illness followed carbon monoxide poisoning in two patients, acute physical exertion in one and contaminated intramuscular injection in the other. Whole-body rectilinear bone scans using technetium 99m-methyldiphosphonate were done. In all patients, increased muscle labelling at the regions of suspected muscle injury was showed, and in one, it was after normalization of serum muscle enzyme levels. In one patient, the bone scan was rechecked 8 months later and showed no residual abnormality. Above all, the site and precise extent of muscle injury could be detected and the degree of muscle labelling seemed to correlate with the severy of muscle injury. These findings suggest that isotope scanning may be useful in the diagnosis of patients with acute muscle necrosis.

The following case study suggests strongly the efficacy of Danggwisusan and acupuncture therapy in the treatment of patients with severe contusion and tissue injury of the liver and kidney. The chief symptoms of this case were severe pain in the right side, purpura hemorrhagica, insomnia and third degree bums at the shoulder and face. Analysis of blood chemistry indicated high AST, high ALT, high BUN, high creatine, high creatine kinase and high LDH. Fallowing medication of the patient with Danggwisusan, the symptoms and indexes for tissue injury decreased rapidily within the first week. This results support a potential role for Danggwisusan in the treatment of severe contusion with tissue injury of the liver and kidney.

Objective : This paper was designed to confirm the relation between Li Dong-yuan(李東垣)'s theory of internal injury(內傷學說) and Neo-confucianism(新儒學)'s academic orientation, particularly Zhang Heung-qu(張橫渠)'s 'Qi-monism(氣一元論)'. Method : Through a comparative literature review, I searched for the commonality between Li Dong-yuan(李東垣)'s theory of internal injury(內傷學說) and Neo-confucianism(新儒學)'s academic orientation, particularly Zhang Heung-qu(張橫渠)'s 'Qi-monism(氣一元論)', and also examined the difference in the meaning of 'Primordial Qi(元氣)' in Qi-monism and that Lee Dong-yuan proposed. Result & Conclusion : The central theme of Neo-confucianism, 'Staying on the Golden Path(允執厥中)', has a commonality with Li Dong-yuan's theory of internal injury that emphasized Primordial Qi, and the concepts of "Great Vacuity as Qi(太虛卽氣)", "Two Properties Inherent in a Single Object(一物兩體)", and "the Nature of Acquired Disposition(氣質之性)" have commonality with the concepts of "The Given from the Vacuity of Natural World(所受於天)", Up & Down Movement(升降運動), and Yin Fire(陰火) of Primordial Qi in Li Dong-yuan's theory of internal injury respectively. However, the concept of Primordial Qi in the Theory of Qi-monism refers to the building blocks of all things in the universe, whereas the concept of Primordial Qi that Li Dong-yuan proposed has no meaning of component of body but driving force that maintains the phenomenon of life.

This study was to investigate the hepatoprotective and anticirrhotic effects of Ganyeumilhobang(GIE) on the acute and chronic liver injury induced by various agents. Chronic liver injury induced by dimethylnitrosamine(DMN) ; a new experimental model for cirrhosis and the intraperitoneal injection of dimethylnitrosamine in the rat. Acute liver njury induced by carbon tetrachloride$(CCl_4)$ and D-galactosamine ; a experimental model for acute liver injury, the administration of $CCl_4$ and the intraperitoneal injection of D-galactosamine in the rat. The development of fibrosis and acute liver injury by the three prescriptions were examined by the chemical analysis of AST, ALT, prothrombin time and hydroxyproline. The results obtained were as follows. 1. The increasing level of hydroxyproline volume induced by DMN in mice was decreased by the oral administration of GIB. 2. The degree of histological fibrosis and hepatic inflammatory cell infiltration induced by $CCl_4$ decreased by the oral administration of GIB. 3. The increase of senun AST and ALT of mice with acute liver damage induced by $CCl_4$ and D-galactosamine was inhibited by the administration of GIB. 4. The prolongation of prothrombin time(seconds) of mice acute liver damage induced by $CCl_4$ was shortened by the oral administration of GIB. 5. The liver of mice was hepatectomized partial1y after the oral administration of GIB. The mitotic index(% of nuclei), weight of liver, contents of protein, RNA and DNA synthesis of the liver tissue were increased by the oral administration of GIB.

Objective : In this study old BCAO rats were observed for effects of 'Dea-Hwang' on brain ischema injury, because risk of stroke increases with age. Method : The brain ischema injury was induced by temporarily closing carotids on both sides in a low blood pressuer state and Dea-Hwang was administered orally to 18 month-old BCAO rats. Results and Conclusions : The ischemically damaged Hippocampus and c-fos and c-jun expression were analyzed by immunohistochemical staining and results are summarized as follows: 1. The c-fos expression after inducing a brain ischema injury in the hippocampus was more inhibited in the dosed group than in the control group. 2. The normalized optical density of c-fos expression was more reduced in the CA1, CA2, and DG areas of the dosed group than in those of the control group. 3. The c-jun expression after inducing brain ischema injury in the hippocampus was more inhibited in the dosed group than in the control group. 4. The normalized optical density of c-jun expression was more reduced in the CAI area of the dosed group than in that of the control group.

Purpose: To evaluate the effectiveness of intraoperative stress test for diagnosis of occult Lisfranc injury. Materials and Methods: Between April 2009 and October 2012, 21 patients with occult Lisfranc injuries underwent intraoperative stress test and internal fixation. There were 11 males and 10 females with an average age of 45.3 years (range, 23~79 years). Injuries were caused by traffic accident in 10 cases, indirect force (twisting injury) in 8 cases, and crush in 2 cases, falling from a height in 1 case. Unstable injuries on stress radiograph in occult injury of Lisfranc joint were treated by open reduction or closed reduction and fixation with cannulated screw or K-wire. Radiological evaluation was assessed according to preoperative and postoperative diastasis between $1^{st}$ and $2^{nd}$ metatarsal base. Results: Assoicated injuries were 9 cases of metatarsal fractures, 6 cases of cuneiform fractures and 6 cases of both metatarsal and cuneiform fractures. Medial and middle column fixation was in 13 cases, and three columns fixation was in 8 cases. Initial diastasis between $1^{st}$ and $2^{nd}$ metatarsal base was 2.8 mm (1.3~4.7 mm) on AP radiograph and postoperative diastasis between $1^{st}$ and $2^{nd}$ metatarsal base was 1.2 mm (0.5~2.4 mm) on AP radiograph. Conclusion: Even there is no sign of clear Lisfranc injury, it is necessary to pay attention and give evaluation on circumstances of occult Lisfranc injuries with metatarsal or cuneiform fractures. Intraoperative stress test is helpful to diagnose an occult Lisfranc injury. For unstable injuries on stress radiographs of occult Lisfranc joint injury, operative treatment with open or closed reduction and internal fixation is useful method.

Fimasartan, a new angiotensin II receptor antagonist, reduces myocyte damage and stabilizes atherosclerotic plaque through its anti-inflammatory effect in animal studies. We investigated the protective effects of pretreatment with fimasartan on ischemia-reperfusion injury (IRI) in a mouse model of ischemic renal damage. C57BL/6 mice were pretreated with or without 5 (IR-F5) or 10 (IR-F10) mg/kg/day fimasartan for 3 days. Renal ischemia was induced by clamping bilateral renal vascular pedicles for 30 min. Histology, pro-inflammatory cytokines, and apoptosis assays were evaluated 24 h after IRI. Compared to the untreated group, blood urea nitrogen and serum creatinine levels were significantly lower in the IR-F10 group. IR-F10 kidneys showed less tubular necrosis and interstitial fibrosis than untreated kidneys. The expression of F4/80, a macrophage infiltration marker, and tumor necrosis factor $(TNF)-{\alpha}$, decreased in the IR-F10 group. High-dose fimasartan treatment attenuated the upregulation of $TNF-{\alpha}$, interleukin $(IL)-1{\beta}$, and IL-6 in ischemic kidneys. Fewer TUNEL positive cells were observed in IR-F10 compared to control mice. Fimasartan caused a significant decrease in caspase-3 activity and the level of Bax, and increased the Bcl-2 level. Fimasartan preserved renal function and tubular architecture from IRI in a mouse ischemic renal injury model. Fimasartan also attenuated upregulation of inflammatory cytokines and decreased apoptosis of renal tubular cells. Our results suggest that fimasartan inhibited the process of tubular injury by preventing apoptosis induced by the inflammatory pathway.

Although there are a few reports concerning the side effects and toxicity of herbal medicines, there has not yet been any report concerning their causes, mechanisms or prevention. We investigated the internal reports concerning the side effects and toxicity of herbal medicines. In the findings, liver disorder (hepatic injury) was found in 7 cases, kidney disorders (nephropathy) were found in 12 cases, heart disorders were found in 4 cases and mineral-caused diseases were found in 2 cases. Besides, we found the major cause of the side effects and toxicity was drug abuse, such as over-dosage and long term medication. So, we hope this report brings more attention to the safety and toxicity of herbal medicines.

배 경 : Matrix metalloproteinase(MMPs), 특히 주로 염증세포에서 분비되는 MMP-9은 여러 가지 급성폐손상 모델 및 급성호흡곤란증후군 환자에서 증가하고, 최근에는 주기적인 물리적 스트레스가 폐포대식세포 및 결체조직세포에서 MMP-9의 생성 및 활성을 증가시키는 것으로 보고된 바 있다. 따라서 본 연구에서는 기계환기로 인한 백서의 급성폐손상에서 MMP-9의 발현 및 MMP 억제제(MMPI)의 효과에 대해서 연구하고자 하였다. 방 법 : Sprague-Dawley 백서를 적은 일호흡량(tidal volume, $V_T$)과 적절한 호기말양압(positive end-expiratory pressure, PEEP)을 적용한 LVT군과 많은 일호흡량과 PEEP을 적용하지 않은 HVT군 및 동일한 조건에서 MMPI를 투여한 HVT+MMPI의 세 군으로 나누어 실험하였다. MMPI로는 CMT-3(chemically modified tetracycline-3)를 기계환기 3일 전부터 구강으로 투약하였다. 폐손상의 정도는 습건중량비와 급성 폐손상지수로 측정하였고, MMP-9의 발현은 면역조직화학염색으로 고찰하였다. 결 과 : 습건중량비, 급성 폐손상지수 및 MMP-9의 발현이 HVT 군에서 다른 두군에 비하여 유의하게 높았고(p<0.05), HVT+MMP군에서 HVT군에 비하여 폐손상의 정도 및 MMP-9의 발현이 현저하게 낮았다(p<0.05). 결과적으로 MMPI의 투여가 MMP-9의 발현을 저하시킴으로써 기계환기로 인한 폐손상의 정도를 유의하게 감소시키는 것으로 관찰되었다 결 론 : 많은 일호흡량과 PEEP을 적용치 않은 기계환기는 폐조직에서 MMP-9의 발현을 유의하게 증가시켜 폐손상을 유발하고, MMPI는 MMP-9의 작용을 억제함으로써 기계환기로 인한 폐손상의 정도를 유의하게 감소시키는 것으로 판단된다.

The early pulmonary consequences of inhalation injury are well documented; however, little is known about delayed pulmonary complications following thermal inhalation injury. Although thermal injury below the vocal cords is rare because of effective heat dissipation in the upper airway, inflammatory endobronchial polyps have previously been reported as a delayed complication associated with inhalation injury. We report an extraordinary case of tracheobronchial polyps in patients with smoke inhalation injury. This report shows the delayed development and natural course of tracheobronchial polyps following thermal injury.
