Objectives: Samul-tang(Siwu-tang) has been traditionally prescribed a medicine as a restorative. Methods: In this study, we investigated the acute toxicity about water-extracted Samul-tang(Siwu-tang). Twenty-five mice completed 14 days of oral Samul-tang(Siwu-tang) at the respective doses of 0(control group), 2560, 3200, 4000 and 5000mg/kg. Results: We observed survival rates, general toxicity, change of body weight, and autopsy. Conclusions: Compared with the control group, we could not find any toxic alteration in all treated groups (2560, 3200, 4000 and 5000mg/kg). $LD_{50}$ of Samul-tang(Siwu-tang) was over 5000mg/kg and it is very safe to ICR mice.

Objectives In this study, we investigated the acute toxicity and safety about fermented Bangpungtongsung-san(Fangfengtongsheng-san) extract. Methods To evaluate the acute toxity and safety, fermented Bangpungtongsung-san (Fangfengtongsheng-san) at the respective doses of 0(control group), 1250, 2500 and 5000 mg/kg were orally treated to 20 male and 20 female mice. After single administration, we observed survival rates, general toxicity, changes of body weight and autopsy.

Botulism in wild waterfowl has been reported in many areas of the world. In 18 October 2008 to 22, 101 dead wild ducks were found in Anyangcheon. 24 of dead birds were spotbill (Anas poeilorhyncha), 56 were Mallard (Anas platyrhynchos), 18 were green- winged teal (Anas carolinensis) and 3 were others. Clinical sign of the sick birds were flaccid paralysis of the neck. At autopsy, most birds had no specific lesions. Stomach is empty. In the mouse bioassay, Samples of serum and intestinal contents taken from 9 dead birds killed all the injected mice, and their toxicity was neutralized by the antitoxin against C. botulinum type C toxin.

An 18-day-old male neonate with hypoplastic left heart syndrome underwent surgical intervention by modification of the Norwood procedure on September 23, 1986. Hypoplastic left heart syndrome is a serious congenital cardiac anomaly that has a fatal outlook if left untreated. Included in this anomaly are [1] aortic valve atresia, and hypoplasia of the ascending aorta and aortic arch, [1] mitral valve atresia or hypoplasia, and [3] diminutive or absent left ventricle. Patent ductus arteriosus is essential for any survival, and there is usually a patent foramen ovale. Coarctation of the aorta is frequently associated with the lesion.z With a limited period of cardiopulmonary bypass, deep hypothermia, and circulatory arrest, the ductus arteriosus was excised. The main pulmonary artery was divided immediately below its branches, and the distal stump of the divided pulmonary artery was closed with a pericardial patch. The aortic arch was incised, and a 1 5mm tubular Dacron prosthesis was inserted between the main pulmonary artery and the aortic arch. A 4mm shunt of polytetrafluoroethylene graft was established between the new ascending aorta and the right pulmonary artery to provide controlled pulmonary blood flow. Following rewarming, the heart started to beat regularly, but the patient could not be weaned from cardiopulmonary bypass. At autopsy, the patient was found to have hypoplasia of the aortic tract complex with mitral atresia and aortic atresia. A secundum atrial septal defect was noted. Right atrial and ventricular hypertrophy was present, and the left ventricle was entirely absent. Although unsuccessful in this case report, continuing experience with hypoplastic left heart syndrome will lead to an improvement in result.

Pulmonary lymphangioleiomyomatosis is a chronic destruct8ive disease of the lung affecting women of childbearing ages which eventually leads to respiratory failure. Lung transplantation is the only conclusive therapeutic measure because this disease responds poorly to other therapies, To date only a few reports in the literature describes the clinical experience of the bilateral sequential lung transplantation of this rare condition. We performed a bilateral sequential lung transplantation on a 32-year-old woman suffering from lymphangioleiomyo-matosisw. The heart-lung block was harvested from a 51-year-old donor. We transplanted the left lung first through the clam-shell incision. As the hemodynamics deteriorated suddenly during the dissection of the right lung the right lung was transplanted under the cardio-pulmonary bypass. Although the patient's lung function was initially satisfactory the patient died of sepsis and subsequent cardiogenic shock at the postoperative 18th day. Autopsy findings showed infection of Candida albicans on the pericardium and the left lung which had been initiated possibly from the left bronchial anastomosis site,. Through detailed review of the clinical course we concluded that lung transplantation could have been performed safely on this disease provided that early diagnosis and proper management or the oppor-tunistic infection have been carried out.

실리콘의 부적절한 피하 주입으로 발생한 폐색전증의 방사선학적 특징은 초기에는 호흡기 증상만 보이지만 염증 매개성 반응이 진행함에 따라 양측 폐 침윤이 급격히 진행하는 것을 볼 수 있었다. 또한 실리콘의 비중이 혈액보다 낮아 중력 비의존성 분포를 보임을 알 수 있었고, 이는 기존의 다른 원인에 의한 폐색전증과 구분되는 소견이다.

The information on mortality from echinococcosis is important not only for a better understanding of the severity of the disease, but also for evaluating the effectiveness of public health interventions. The aim of this research was to study the causes of mortality from echinococcosis. We have collected and analyzed the materials of 1,470 patients in 10 age - groups in the Republic of Armenia (from 2000 to 2016). To find out the causes of mortality from echinococcosis, we have analyzed the medical histories and protocols of postmortem examinations of 19 deaths from echinococcosis and 17 deaths due to other indirect causes not associated with the parasite. The average annual death rate from echinococcosis is 0.007 per 10,000 population, and the mortality is 1.29 (per 100 patients). The highest mortality occurs in people aged 70-79. Mortality from echinococcosis is also recorded among the unoperated children. The rupture of the parasitic cyst and hepatic insufficiency are major among the direct causes of mortality. Sometimes the hydatid cysts unrecognized during the life were first diagnosed at autopsy. Insufficient qualification of doctors in the field of helminthology, as well as the latent course of the disease or manifestation of minor symptoms in echinococcosis over a long period often led to medical errors. Further decline in mortality can be achieved by early diagnosis, timely hospitalization and treatment before the development of severe complications worsening the prognosis and outcomes of surgical intervention.

We have performed four left lung reimplantation and right pulmonary artery ligation in dogs for six months from March 1989 to September 1989 at the Thoracic & Cardiovascular Surgery department, Yonsei University, College of Medicine, Seoul, Korea. Excised left lungs were perfused with 200cc of 4oC cold saline at a pressure of 60cmH2O through left pulmonary artery & preserved in 4 oC cold saline for about 20 mins. Left lung reimplantation were proceeded with inferior pulmonary vein, superior pulmonary vein, left pulmonary artery and left main bronchus in order. The main pulmonary artery pr. were 39/21[31], 22/12[15], 25/9[15] and 54/17[37] mmHg each after right pulmonary artery ligation on left reimplanted dogs, Right pul a. ligations were performed 9 days, 12 days, 16 days and 19 days after left lung reimplantation. Two dogs died at 10 days 21 days, after right pul. a. ligations in left reimplanted dogs. The remaining two dogs were sacrificed at 18 days, 21 days after right pul. a. ligation in left reimplanted dogs. Autopsy findings showed narrowing of left superior pul. vein anastomotic site in two narrowing of left pulmonary artery anastomotic site in one narrowing of left sup. pul vein & pneumonia of left lung in one. In the lung transplantation, it was thought to be important that the anastomosis of pulmonary artery and especially pulmonary vein be done with particular precaution for early and late stenosis.
