Hepatopulmonary syndrome (HPS) is a serious complication of end-stage liver disease, which is characterized by hypoxia, intrapulmonary vascular dilatation, and liver cirrhosis. Liver transplantation (LT) is the only curative treatment modality for patients with HPS. However, morbidity and mortality after LT, especially in cases of severe HPS, remain high. This case report describes a patient with typical findings of an extracardiac pulmonary arteriovenous shunt on contrast-enhanced transesophageal echocardiography (TEE), and clubbing fingers, who had complete correction of HPS by deceased donor LT. The patient was a 16-year-old female who was born with biliary atresia and underwent porto-enterostomy on the 55th day after birth. She had been suffered from progressive liver failure with dyspnea, clubbing fingers, and cyanosis. Preoperative arterial blood gas analysis revealed severe hypoxia (arterial O2 tension of 54.5 mmHg and O2 saturation of 84.2%). Contrast-enhanced TEE revealed an extracardiac right-to-left shunt, which suggested an intrapulmonary arteriovenous shunt. The patient recovered successfully after LT, not only with respect to physical parameters but also for pychosocial activity, including school performance, during the 30-month follow-up period.

안면경련의 침구치료에 대한 문헌적 고찰

조현석,장준혁,김경호,윤종화,김갑성 동국대학교 한의학연구소 1999 東國韓醫學硏究所論文集 Vol.7 No.2

편측 안면경련은 편측 안면근의 불수의적, 간헐적 수축으로서 심할 경우 안면 근력 약화 및 강직현상등이 나타나기도 하는 질환이다. 서양의학에서 편측 안면경련의 병태생리에 대한 가설은 크게 두가지로 대별되는데, 첫째는 중추성 가설(핵가설)이고, 둘째는 말초성가설이다. 치료방법은 대별하여 내과적 치료와 외과적 치료의 나눌 수 있는데, 외과적 치료가 다양하게 시행되어 왔으며, 근래에는 두개강내 미세혈관 감압술이 시행되고 있다. 韓醫學에서는 眼瞼痙攣울 眼胞振跳, 胞輪振跳라고 하고, 眼眉跳라고도 하며, 그 외 目瞬, 目跳, 眼皮跳 등의 이름으로도 불리운다. 外因으로는 風邪가 經絡에 侵入하는 것이며, 內因으로는 肝血虛한 中의 風邪가 兼하기 때문이다 따라서, 국부경혈 자침과 함께 장부변증에 따라 肝, 膽經 경혈의 사용과 합께 耳鍼T의 시술이 유용할 것으로 사료된다. Hemifacial spasm including blepharospasm is characterized by spontaneous clonic and tonic muscle spasm on one side of the face with synkinesis. Though the etiology of hemifacial spasm is not entirely understood, generally there are two. One is nuclear hypothesis and the other is peripheral hypothesis. There are two ways of treatment of hemifacial spasm. One is internal medicine and the other is operative method. In oriental medicine, hemifacial spasm is very similar to diseases such as Anpojindo(眼胞振跳), Poryunjindo(胞輪振跳), or Anmido(眼眉跳) in symptoms. The diseases such as Anpojindo(眼胞振跳), Poryunjindo(胞輪振跳), Anmido(眼眉跳) is related to the function of liver(肝) and risk factors are regarded as Pung(風). The acupuncture therapy of hemifacial spasm is based on Liver meridian(LV), Gallbladder meridian(GB), And ear-acupuncture is recommended as a good method for hemifacial spasm.

The influences of preageing on age-precipitation in Al-2.02t% Cu-1.1wt% Mg alloy have been investigated by means of measurements of hardness, tensile strength and electrical resistivity and transmission electron microscopy. The results obtained are summarized as follows. The two-step aged alloy is more age-hardenable than the onestep aged alloy in early stage of ageing. It is because of the formation and growth of solute atom cluster and GPB zones. The maximum hardness and strength of the alloy aged 200℃ is obtained by preaged at 100℃. It is because of fine and dense distribution of S'metastable phase. The hardness and strength are remarkably decreased with sufficient ageing time after preageing at room temperature and 170℃. It is because of the formation and coarsening of S'metastable phase by the preageing.

The weight of kidney bean soaking in various soaking solution increased as function of soaking temperature at 10˚-50℃. Under the 30℃ of soaking temperature, water equilibriumstate of kidney bean In various soaking solution was not reached in 12 hours, however, bean soaking in distilled water at 50℃reached water equilibrium after 11 hours of soaking and that of another four soaking solution reached water equilibrium almost in 7 hours. Water equilibrium content of kidney bean were 117.Ol% soaking in distilled water and 128.33% in 0.5% NaHCO_3, solution. Water uptake rate constant(K) of kidney bean in various soaking solution Increased as function of soaking temperature and the increase of water uptake rate constant was the highest in distilled water and the lowest in 0.5% NaHC0_3 solution. Activation energy for weight gain of kidney bean soaking in various solution at 10~30℃was 1.2 tlmes greater than that of 30˚∼50℃. The z-value of kidney bean soaking at 10˚∼50℃ decrease with increase hydration degree and z-value to reach 40% hydration estimated from weight increase was 122℃at 10˚∼30℃ and 40℃ at 30˚~50℃and z-value of bean in 0.5% NaHCO_3 solution was 82℃ at 10˚~30℃and 58℃ at 30˚∼50℃. Volume increase rate of kidney bean increased as function of soaking temperature and kidney bean soaking at 50℃ in various solution reached volume equilibrium state in 10 hours and among these bean in distilled water reached later than the other solutions. Volume increase rate constant increased with soaking temperature, among these the increase of kidney bean soaking in 0.5%t NaHCO_3 solution was the highest. The z-value of 40% hydration estimated volume increase decreased with increase hydration degree. The time to reach a complete cooking of kidney bean In distilled water was 35 minutes, the longest and the time was reduced to 11, 7, 5 and 3 minutes soaking in 0.5% NaHCO_3.solution. 0.4% NaHCO_3+0.1% NaCl combination solution, 0.1% NaHC0_3+0.4% NaCl combination solution 0.5% NaHCO_3 solution, respectively. When the kidney bean was cooked for 20 minutes after soaking 0.575 NaHC0_3 solution, the cooking rate was faster than that of the other solution. Cooking rate constant of kidney bean in 0.5% NaHCO_3 solutions. Kidney bean in 0.5% NaHCO_3 solution. cooking rate constant of the first stage was the highest. which was 5 times of the constant of the second stage and in distilled water, the cooking rate constant of the first stage was about 7 times of the second stage.

To evaluate the accuracy and diagnostic significance of cytopathological diagnosis of canine splenic disorders, cytopathological examination throgh fine-needle aspiration(FNA) referred to Veterinary Medical Teaching Hospital of Chungnam National University were retrospectived. Splenic neoplasm, hemolymphatic neoplasm, hyperplasia, extramedullary hematopoiesis and splenitis were diagnosed canine splenic disorders through cytopathological examination. The patient should be identified what coagulation profile are normal before aspiration, because complication such as hemorrhage could happen. The 4 cases were identified symmetric, asymmetric splenomegaly on abdominal ultrasonography and then were performed ultrasound-guided FNA. The 4 cases were diagnosed hemangiosarcoma(2), hyperplasia(1) and extramedullary hematopoiesis(1) by clinical signs, hematological examination, and cytopathological examination. Cytopathological examination through FNA was cost-effective, no gneral anesthesia, no complication, and non-invasive method of diagnosis for canine splenic disorders.
