Background: In kidney transplantation, donor specific transfusion may induce tolerance as a result of some immune regulatory cells against the graft. In organ transplantation, the immune state arises from a relationship between the immunocompromised graft and the immunocompetent host. However, a reverse immunological situation exists between the graft and the host in hematopoietic stem cell transplantation (HSCT). In addition, early IL-2 injections after an allogeneic murine HSCT have been shown to prevent lethal graft versus host disease (GVHD) due to CD4+ cells. We investigated the induction of the regulatory CD4+CD25+ cells after a transfusion of irradiated recipient cells with IL-2 into a donor. Methods: The splenocytes (SP) were obtained from 6 week-old BALB/c mice (
연구배경 : 폐쇄성 수면무호흡증후군은 다양한 원인에 의해 발생하게 된다. 주된 위험요소로는 비만과 좁은 상기도, 비정상적인 머리-얼굴 구조 등이 알려져 있으며 유전적 요인 또한 가족내 집단적 발생하였다는 보고들에 의해 뒷받침되고 있다. 본 연구에서 저자들은 HLA검사를 통하여 폐쇄성 수면무호흡증후군에서 유전학적인 배경을 규명하고자 하였다. 방 법 : 철야 수면다원검사로 진단한 25명의 폐쇄성 수면무호흡증후군 환자 (여자 1명과 남자 24명, 연령 30-66세)를 대상으로 하였으며 대조군은 200명의 건강한 한국인으로 하였다. HLA-A와 -B 대립유전자의 검사는 미세세포독성검사로 시행하였고 HLA-DRB1 유전자의 두번째 엑손의 다형성에 대한 분석은 PCRSSOP방법을 이용하여 시행하였다. 결 과 : HLA-A11 대립유전자의 빈도는 폐쇄성 수면무호흡증후군 환자군에서 대조군에 비해 유의하게 감소되어 있었다 (p<0.05). HLA-B 대립유전자의 빈도는 양군간에 유의한 차이가 없었다. HLA-DRB1 유전자의 다형태 분석에서는 DRB1*09의 빈도가 폐쇄성 수면무호흡환자군에서 대조군에 비해 유의하게 증가되어 있었다 (p <0.05). 환자군을 무호흡지수 45를 기준으로 경-중등증군과 중증군으로 나누어 대조군과 비교하였을 때 중증군에서 HLA-DRB1*08의 빈도가 유의하게 증가되어 있었다 (p <0.05). 결 론 : 한국의 폐쇄성 수면무호흡증후군 환자에서 HLAA11과 DRB1*09가 폐쇄성 수면무호흡증후군과 관련되어 있고, HLA-DRB1*08이 이 질환의 중증도와 연관되어 있음을 알 수 있었다. 이상의 결과는 폐쇄성 수면 무호흡 증후군의 발생뿐 아니라 경중도 여부에도 유전적인 요소가 중요한 역할을 한다는 것을 시사한다.
Cough is the most common respiratory symptom that can have various causes. It is a major clinical problem that can reduce a patient's quality of life. Thus, clinical guidelines for the treatment of cough were established in 2014 by the cough guideline committee under the Korean Academy of Tuberculosis and Respiratory Diseases. From October 2018 to July 2020, cough guidelines were revised by members of the committee based on the first guidelines. The purpose of these guidelines is to help clinicians efficiently diagnose and treat patients with cough. This article highlights the recommendations and summary of the revised Korean cough guidelines. It includes a revised algorithm for the evaluation of acute, subacute, and chronic cough. For a chronic cough, upper airway cough syndrome (UACS), cough variant asthma (CVA), and gastroesophageal reflux disease (GERD) should be considered in differential diagnoses. If UACS is suspected, first-generation antihistamines and nasal decongestants can be used empirically. In cases with CVA, inhaled corticosteroids are recommended to improve cough. In patients with suspected chronic cough due to symptomatic GERD, proton pump inhibitors are recommended. Chronic bronchitis, bronchiectasis, bronchiolitis, lung cancer, aspiration, intake of angiotensin-converting enzyme inhibitor, intake of dipeptidyl peptidase-4 inhibitor, habitual cough, psychogenic cough, interstitial lung disease, environmental and occupational factors, tuberculosis, obstructive sleep apnea, peritoneal dialysis, and unexplained cough can also be considered as causes of a chronic cough. Chronic cough due to laryngeal dysfunction syndrome has been newly added to the guidelines.
1. The 'Kao Zheng Pai(考證派) comes from the 'Zhe Zhong Pai' and is a school that is influenced by the confucianism of the Qing dynasty. In Japan Inoue Kinga(井上金娥), Yoshida Koton(吉田篁墩) became central members, and the rise of the methodology of historical research(考證學) influenced the members of the 'Zhe Zhong Pai', and the trend of historical research changed from confucianism to medicine, making a school of medicine based on the study of texts and proving that the classics were right. 2. Based on the function of 'Nei Qu Li '(內驅力) the 'Kao Zheng Pai', in the spirit of 'use confucianism as the base', researched letters, meanings and historical origins. Because they were influenced by the methodology of historical research(考證學) of the Qing era, they valued the evidential research of classic texts, and there was even one branch that did only historical research, the 'Rue Xue Kao Zheng Pai'(儒學考證派). Also, the 'Yi Xue Kao Zheng Pai'(醫學考證派) appeared by the influence of Yoshida Kouton and Kariya Ekisai(狩谷掖齋). 3. In the 'Kao Zheng Pai(考證派)'s theories and views the 'Yi Xue Kao Zheng Pai' did not look at medical scriptures like the "Huang Di Nei Jing"("黃帝內經") and did not do research on 'medical' related areas like acupuncture, the meridian and medicinal herbs. Since they were doctors that used medicine, they naturally were based on 'formulas'(方劑) and since their thoughts were based on the historical ideologies, they valued the "Shang Han Ja Bing Lun" which was revered as the 'ancestor of all formulas'(衆方之祖). 4. The lives of the important doctors of the 'Kao Zheng Pai' Meguro Dotaku(目黑道琢) Yamada Seichin(山田正珍), Yamada Kyoko(山田業廣), Mori Ritsi(森立之) Kitamura Naohara(喜多村直寬) are as follows. 1) Meguro Dotaku(目黑道琢 1739
