Reactive disorder is a group of diagnosis with a definitely known etiology and whose etiological factor is essential to the diagnosis. In DSM system, such reactive disorders are listed as adjustment disorder, acute stress disorder, brief psychotic disorder with marked stressor and posttraumatic stress disorder (PTSD). However, a growing number of individuals is suffering from a prolonged feeling of embitterment after exceptional negative life events and this condition could be diagnosed neither PTSD nor adjustment disorder nor depressive disorder in the context of DSM-IV diagnostic system. This clinical condition can be described as 'posttraumatic embitterment disorder' (PTED). PTED is a reactive disorder triggered by exceptional, though normal negative life events such as conflict in the workplace, unemployment, death of a relative, divorce, severe illness, or experience of loss or separation. The common feature of such events is that they are experienced as unjust, as a personal insult, accompanied by psychological violation of basic beliefs and values. The central psychopathological response pattern in PTED is a prolonged feeling of embitterment. In particular, the core emotion of embitterment can lead to the rejection of treatment. Therefore, "wisdom therapy" as a new treatment approach specifically designed for PTED has been developed. It is assumed that many patients suffering from PTED are often misunderstood and misdiagnosed. This review would help to introduce PTED into the clinical field in psychiatry.

The human complement receptor type 1 (CR 1, C3 b/C4b receptor) is a polymorphic membrane glycoprotein expressed on human erythrocytes, peripheral leukocytes, plasma and renal glomerular podocytes, which consists of transmembrane and cytoplasmic domains with 30 repeating homologous protein domains known as short consensus repeats (SCR). CR1 has been used as an inhibitor for inflammatory and immune system for the past several years. Recently; it is reported that CRl was found to suppress the hyper-acute rejection in xeno-transplantation and can be used to cure autoimmune diseases. A soluble form of CRl, called sCRl, is a recombinant CRl by cleaving the transmembrane domain at C-terminus and has been expressed in Chinese Hamster Ovary (CHO) cells. Several purification methods for sCR1 from CHO cells have been reported, but most of them require complicated steps at high cost. Moreover, such methods are mostly performed under the pH condition apt to denaturing sCR1 and causes sCRl losing its activity. We here report a rapid and efficient method to purify sCR1 from CHO cell. The new method consists of a two-stage of cell culture by cultivating cells in serum medium followed by serum-free medium, and a two-stage of column purification by means of heparin and gel filtration column chromatography. By using this novel method, sCR1 can be purified in a simple and effective way with high yield and purity, furthermore, the purified sCR1 was confirmed to retain its activity to suppress the complement activation in vivo and ex vivo.

Purpose: The purpose of this longitudinal study was to identify the relationship between the readiness for hospital discharge and self-care changes in an early stage of liver transplantation after discharge. Methods: Data of 75 liver transplant recipients within one year of surgery from a transplantation center from May 2019 to May 2020 were collected for this study. Their readiness for discharge was measured before discharge. Self-care after liver transplantation was evaluated at one week, one month, and three months of discharge at outpatient visits. Linear mixed model was used to evaluate the statistical relationship. Results: The readiness for hospital discharge was significantly higher when the caregiver was a spouse (p=.027), with fewer post-transplantation days (p=.027), absence of acute rejection (p=.004), or high self-efficacy (p<.001). As a result of the linear mixed model analysis, the higher the discharge readiness score, the higher the self-care score (β=0.29, p<.001). However, after three months, their self-care had decreased regardless of their level of readiness for hospital discharge compared to one week after discharge. Conclusion: Improving the readiness before discharge is essential to enhance self-care. Also, active intervention at 3 months of discharge should be performed to check and promote their long-term self-care.

Backgrounds/Aims: Prolonged use of steroids after liver transplantation (LT) significantly increases the risk of diabetes or cardiovascular disease, which can adversely affect patient outcomes. Our study evaluated the effectiveness and safety of early steroid withdrawal within the first year following LT. Methods: This study was conducted as an open-label, multicenter, randomized controlled trial. Liver transplant recipients were randomly assigned to one of the following two groups: Group 1, in which steroids were withdrawn two weeks posttransplantation, and Group 2, in which steroids were withdrawn three months posttransplantation. This study included participants aged 20 to 70 years who were scheduled to undergo a single-organ liver transplant from a living or deceased donor at one of the four participating centers. Results: Between November 2012 and August 2020, 115 patients were selected and randomized into two groups, with 60 in Group 1 and 55 in Group 2. The incidence of new-onset diabetes after transplantation (NODAT) was notably higher in Group 1 (32.4%) than in Group 2 (10.0%) in the per-protocol set. Although biopsy-proven acute rejection, graft failure, and mortality did not occur, the median tacrolimus trough level/dose/weight in Group 1 exceeded that in Group 2. No significant differences in safety parameters, such as infection and recurrence of hepatocellular carcinoma, were observed between the two groups. Conclusions: The present study did not find a significant reduction in the incidence of NODAT in the early steroid withdrawal group. Our study suggests that steroid withdrawal three months posttransplantation is a standard and safe immunosuppressive strategy for LT patients.

Studies on diagnosis and treatment of tumor . abscess . ulcer in intestinal carbuncle were carried out. The result of studies were summerized as follows: 1. By Nai-Gyung carbuncle-tumor arose from disharmony between nutrient and defensive because of cold, abscess arose from fever victory between cold and fever, ulcer arose from decreasing function of Bi-Kam year. By latter literature Bi-Kam year could be interpreted that spleen stomach was invaded evil influence from unattainable vital force of the earth. 2. Sites of intestinal carbuncle were large intestine, small intestine, intestinal inside or outside between large and small intestine, Intestinal carbuncle was common name of a disease about large intestinal carbuncle, small intestinal carbuncle, pelvic intestinal carbuncle, shrink leg intestinal carbuncle etc.. Pain appeared Chunchu-Hyul in large intestinal carbuncle, and Gwanweon-Hyul in small intestinal carbuncle. 3. On abdominal diagnosis tumor had indistinct pain of Gwanweon Chunchu, edema and heary feeling in low abdomen, no excessive pain by hand press and intestinal boiling sound. In abscess pain descended from right side of low abdomen to huckle, and there was rejection against press, feeling about fever,water sound with flank movement. In ulcer hand approach was difficult since excessive pain diffuse to whole abdomen, and perforating ulcer sometimes caused a serious symptom of umbilical pus. 4. On fecal and urinary diagnosis in tumor urine was yellowish red pollakiuria like gonorrhoea and occasional constipation. In abscess uncomfortable rough pain short red early urine like gonorrhoea appeared during urination, and constipation with stinging pain appeared during defecation. In ulcer red rough pyuria appeared, and stinging and pain with puruloid blood appeared during defecation. 5. On treatment in tumor Daiwhang-Tang Daisenggi-Tang Dangui-Jun by dissipation method, calming down method, interior reliance maturation method, in abscess Mokdan-San Euiiin-Tang Jeokduiin-Tang by the method of water repelling pus discharge, acute breaking, in ulcer Takridanggui-Tang Paljin-Tang Bojungikki-Tang were each used by the method of interior reliance, virulence astriction, supplement vital force and blood, supplement spleen stomach. 6. On treatment patient may have to be careful of excessive moving and suprising anxiety. Abuse of acupuncture and moxibustion made patient worse, misuse of analgesics purgative intestinal irrigation etc. could provoke difficult diagnosis and perforation. So you must treat after exact diagnosis. 7. Prognosis of ease tumor ease abscess ease ulcer and ease astriction was good. If the intestinal carbuncle were not to promote to abscess and ulcer for a long time, its prognosis was bad and it could metastasize to cancer because of dark purple with hardness. So tumor abscess ulcer in intestinal carbuncle may be significant of precancerous lesion.

Background: Orthotopic organ transplantation, a treatment option for irreversible organ dysfunction according to organ failure, severe damaged organ or malignancy in situ, was usually accompanied with massive blood loss thus transfusion was required. We aimed to evaluate the adverse impact of blood transfusion on solid organ transplantation. Materials and Methods: From January, 2009 to December, 2014, patients who received orthotopic organ transplantation at Far Eastern Memorial Hospital medical center were enrolled. Clinical data regarding anemia status and red blood cell (RBC) transfusion before, during and after operation, as well as patient outcomes were collected for further univariate analysis. Results: A total of 105 patients who underwent orthotopic transplantation, including liver, kidney and small intestine were registered. The mean hemoglobin (Hb) level upon admission and before operation were $11.6{\pm}1.8g/dL$ and $11.7{\pm}1.7g/dL$, respectively; and the nadir Hb level post operation and the final Hb level before discharge were $8.3{\pm}1.6g/dL$ and $10.2{\pm}1.6g/dL$, respectively. The median units (interquartile range) of RBC transfusion in pre-operative, peri-operative and post-operative periods were 0 (0-0), 2 (0-12), and 2 (0-6) units, respectively. Furthermore, the median (interquartile range) length of hospital stay (LHS) from admission to discharge and from operation to discharge were 28 (17-44) and 24 (16-37) days, respectively. Both peri-operative and post-operative RBC transfusion were associated with longer LHS from admission to discharge and from operation to discharge. Furthermore, it increased the risk of post-operative septicemia. While peri-operative RBC transfusion elevated the risk of acute graft rejection in patients who received orthotopic transplantation. Conclusions: Worse outcome could be anticipated in those who had received massive RBC transfusion in transplantation operation. Hence, peri-operative RBC transfusion should be avoided as much as possible.

허혈/재관류 손상은 장기이식 분야에서 해결해야 할 주요 문제점으로 알려져 있다. 본 연구에서는 대퇴 동,정맥 부위에서 기존의 혈관 문합법 대신 맥관 connector를 이용하여 간단하면서 효과적인 체외 재관류 모델을 개발하였기에 소개하고자 한다. 개발된 모델이 허혈/재관류 손상연구에 효과적인지 알아보기 위해 혈액 동력학적 평가와 신장의 재관류 후 손상 양상을 분석하였다. 기존의 재관류 모델에서 사용되는 문합 부위인 복강 대동맥의 혈압과 본 연구에서 재관류 부위로 활용된 대퇴동맥의 혈압은 유의적 차이가 없었다. 허혈 손상 후 재관류 효과를 알아보기 위해 미니돼지에서 적출한 신장을 HTK 용액에 24, 48시간 동안 각각 저온보관 후 대퇴부에 이식하여 재관류 한 결과, 신장의 재관류까지 수술시간은 평균 $7.0{\pm}1.1$분 소요되었으며, 3시간 재관류 후 재관류 손상 정도는 저온보관시간에 따라 증가되는 것이 확인되었다. 이는 개발된 모델이 맥관 문합 없이 간단한 관류방법이면서도 기존의 복잡한 수술에 의한 재관류 방법과 유사한 손상 모델을 만들 수 있는 효과적인 허혈/재관류 동물모델이라는 것을 의미한다. 따라서 본 연구에서 개발한 신장 재관류 모델은 초기 허혈/재관류 손상 연구와 장기이식에서 이식면역연구에 효과적인 모델이라 사료된다.

About Oui-Ga-Sil(胃家實) in order to considerate the contents recorded in Nai-Gyung Sang-Han-Lon and latter literature, definition, etiopathology, syndrome, differential diagnosis, therapy, Prognosis and prevention were classified. And the results were as follows: 1. Oui-Ga(胃家)was a term which indicated the whole digestive system such as stomach, small intestine, large intestine, rectum and anus. Sil(實)could be defined as the peculiar concept pertaining to the acute and last stage which was invaded to inside bowels because of abundance with evil influence. 2. Eliology of Oui-Ga-Sil was abunt gastric fever originally, injured mucus because of mistreatment, the invasion to inside of outside evil influence through meridian. Pathology was the opening and shutting appearance of gastric abundance with intestinal emptiness, and intestinal abundance with gastric emptiness, Oui-Ga-Sil could be occurred because of gastric abundant dryness and splenic humidifying capacity decrease. 3. Symptom of Oui-Ga-Sil was classified as for the sunlight outside syndrome and the inside abundant syndrome. The sunlight outside syndrome was body fever, sweating, no chilling, on the contrary hatred of fever. The chief complaint of inside abundant syndrome was daily fever, talking in delirium, hand and foot sweating, abdominal distention, difficult defection and those could be pertained to sunlight bowel syndrome. 4. Diagnostic views of Oui-Ga-Sil were that pulse was descending abundant large strong and smooth quick, a coated tongue was yellow, deep yellow, old yellow, thick, scorching dry rough or gray black. On abdominal diagnosis, pressing by hand, patient was conscious of pain, excessive pain, rejection against press, impossible press or intermittent abdominal pain and bowel cutting pain without press. 5. Differential diagnosis was that the sunlight of Nai-Gyung-Fever-Theory was outside desease making meridian the prime object, Baik-Ho-Tang syndrome was making figureless abundant fever the pivotal point. And important differential standard of splenic shrink syndrome was that a daily fever, an irritation with fever were not occurred. 6. Theory of Oui-Ga-Sil was that Seng-Gi-Tang classes had been used in attacking downward or making balance, and moxibustion on Jung-Wan, honey boiling induction theory had been also used. Attacking downward therapy was invigorating method to preserve mucus, and if mucus had been exausted with complicating emptiness prognosis had been appeared badly. 7. Preventing from Oui-Ga-Sil diet by rule, fitness to cold and warmth may be needed to prevent outside evil influence attack and inside evil influence occurrence. Prudence with being very busy, fatigue, wine and woman may be also needed not to be an injury to splanic and gastric spirit.

Transplantation is considered to be a very useful approach to improve human welfare and to prolong life-span. Heterologous organ transplantation using pig organs which are similar to human beings and easy to make mass-production has known as one of the alternatives. To ensure potential usage of the pig organ for transplantation application, it is essentially required to generate transgenic pig modifying immuno-related genes. Previously, we reported production of heterozygous ${\alpha}1,3$-galactosyltransferase (GalT) knock-out and human membrane cofactor protein (MCP) expressing pig ($GalT^{-MCP/+}$), which is enforced for suppression of hyperacute and acute immunological rejection. In this study, we reported generation of homozygous pig ($GalT^{-MCP/-MCP}$) by crossbreeding $GalT^{-MCP/+}$ pigs. Two female founders gave birth to six of $GalT^{-MCP/-MCP}$, and seven $GalT^{-MCP/+}$ pigs. We performed quantitative real-time PCR, western blot, and flow cytometry analyses to confirm GalT and MCP expression. We showed that fibroblasts of the $GalT^{-MCP/-MCP}$ pig do not express GalT and its product Gal antigen, while efficiently express MCP. We also showed no expression of GalT, otherwise expression of MCP at heart, kidney, liver and pancreas of transgenic pig. Taken together, we suggest that the $GalT^{-MCP/-MCP}$ pig is a useful candidate to apply xenotransplantation study.

루이라벨의 사상에서는 현대철학에서 거의 다루지 않고 있는 '선과 악'에 대한 주제가 매우 중요한 개념으로 등장하고 있다. 그의 사유에서 악의 개념은 '악이란 존재의 부족'이라는 스콜라철학의 소극적인 규정에서 출발하고 있지만, 세계에 현존하는 악이란 '삶과 가치'를 파괴하는 의지적인 힘으로, 즉 도덕적인 차원에서 보다 적극적인 의미로 규정하고 있다. '악의 현존(la $pr{\acute{e}}sence$ du mal)'을 '세계의 스캔들(le scandale du monde)'로서 규정하는 그의 사유에는 모든 인간이 의지의 태도로서의 악의 가능성을 지니고 있으며, 세계와 인간사회에서의 악의 현존은 필연적인 것임을 말해주고 있다. 반면 악의 결과가 육체적 정신적인 '고통'으로서 나타나기에, 고통을 거부하고자 하는 인간의 '고통에 대한 태도'는 이러한 악을 극복하고자 하는 도덕적인 의지를 유발하게 한다. 악의 현존 앞에서 가지게 되는 '내적인 고통'인 '도덕적인 고뇌'는 그 자체 '도덕적인 존재'가 된다는 의식을 가지게 하고 여기서 자기만족을 가지게 되는 것이다. 비록 고통스럽지만 도덕적인 존재가 됨에 대한 자기만족과 행복감은 인간이 악의 현존에 맞서 이를 초극할 수 있는 유일한 계기이자 동기이다. 즉 라벨의 선과 악에 대한 사유는 '도덕 심리주의'에 기초해 있으며, 고통에 대한 거부와 도덕적 고뇌에 있어서의 '심리적 지평과 윤리적 지평의 일치'가 인간으로 하여금 끊임없이 악을 극복하고 선을 산출하도록 한다는 '윤리적 낙관론'을 가능하게 하고 있다. 이는 분명 스콜라 철학의 발전된 현대적인 적용이라고 할 수 있겠으나, 또한 '악을 유발하는 의지의 태도에 대한 구체적 양태의 분석', '사회 속에 현존하는 악의 구체적인 양태들' 그리고 이러한 악을 초극할 수 있는 '의지적인 노력의 다양한 양상' 등에 대한 분석은 이루어지고 있지는 않다. 이러한 구체성의 부족은 선과 악에 관한 라벨의 사유가 여전히 소극적인 면모를 보이고 있다고 할 수 있다.
