The tracheostomy directs external air into the airway tract. This process causes mucosal dryness, irritation and inflammation in the tracheo-bronchial tree. In order to prevent such problems, several methods are applied; ointment application, humidification and careful suction etc. The heat-moisture exchanger (HME) is commercially sold device that assists heating and humidification of the inhaled air. The authors experienced successful treatment outcome of intractable tracheitis caused by repetitive and vigorous intra-tracheal suction by applying HME in a total laryngectomized patient. We report an interesting and didactic case with a brief literature review.

닭의 산란능력에 영향을 미치는 요인들을 개괄하였으며 특히 바이러스성 질병에 대하여 논의하였다. 전염성질병은 예측할 수 없는 상황에서 발생하므로 질병의 발생을 방지할 수 있는 모든 방법들이 사전에 강구되어야만 한다. 최근들어 전염성기관염이 전국적으로 확산됨에 따라 채란계농가나 종계농가의 피해가 날로 높아가리라 사료되며, 우리 모두의 지혜를 모아 어려움을 슬기롭게 풀어가야 하리라 믿는다

Nine monoclonal antibodies directed against infectious bovine rhinotracheitis virus (IBRV) were prepared by using cell hybridization technique, and the biological properties of the antibodies were investigated by means of immunofluorescence, serum neutralization, and electrophoretic analysis. Eight of 9 monoclonal antibodies reacted specifically with the antigenic constituents of IBRV, infectious laryngotracheitis virus, Marek's disease virus, turkey herpesvirus, hog cholera virus, porcine parvovirus and transmissible gastroenteritis virus. However, the remaining one, 26-2 clone, was found to be cross-reactive with pseudorabies virus. Two monoclonal antibodies, 7-C-2 and 12-A-2, which had neutralizing activity, were reactive with the molecular weights of 72 kilo daltons (72K) and 125K of IBRV proteins electrophoretically separated, respectively. The monoclonal antibody, 3-H-3, which is corresponding to 94K of IBRV proteins, revealed no neutralizing activity. The cross-reactive monoclonal antibody, 26-2, was proved by electrophoretical analysis to be reactive with 100K of IBRV proteins and 40K of pseudorabies virus.

[ $\lceil$ ]금년도에 양계분야에서 뉴캣슬병의 발생은 극히 심하여 전국적인 발생과 피해가 증가되고 있다. 또한 이는 닭 뿐만 아닌 꿩, 금계, 공작등의 조류에도 발생되고 있다. 따라서 일반양계농가에서는 뉴캣슬병이 아닌 다른 호흡기병이 아닌가? 왜 뉴캣슬백신을 실시하였는데 뉴캣슬병이 발생하는가 하는등의 의심을 많이 갖고 있어 금회부터는 뉴캣슬병과 유사한 전염병 특히 아직까지 우리나라에서 발생보고 되지 않은 병을 중심으로 알아 보고저 한다. 따라서 본고는 생소한 전염병이기에 양계업자는 물론 닭 질병을 전문으로 취급하는 분에게도 참고(검색)가 되도록 내용을 엮었다.$\rfloor$

A total of 3 hybridoma clones producing monoclonal antibody (MCA) against infectious laryngotracheitis virus (ILTV) was established by somatic cell hybridization between mouse myeloma cells and spleen, cells from mice immunized with ILTV. The MCAs were screened by the indirect flourescent antibody (IFA) staining and the specific hybridomas were cloned by limiting dilution method. The MCAs produced by the 3 hybriomas were all classified as immunogloblin G and found to be reacting against common antigen(s) of high and low pathogenic ILTV examined. The titer of these antibodies in mouse ascitic fluid was from $10^5$ to $10^6$. Indirect fluorescent antibody test using these antibodies was found to be quite effective for the detection of ILTV from infected chickens being the most sensitive among the test methods adopted.

Vascular ring, originating from abnormal regression of the aortic arch during fetal life, can cause prolonged and recurrent respiratory symptoms and dysphagia when the diagnosis is delayed. We report a 4 month old girl with vascular ring, who had been treated for persistent respiratory symptoms including stridor, wheezing, and dyspnea soon after birth. Initially her respiratory symptoms were thought to be due to bronchiolitis, for which respiratory syncytial virus was confirmed by immunofluorescent staining. Her clinical course was again complicated with tracheitis and pneumonia due to Haemophilus influenzae type b. The possibility of anatomical anomaly was investigated when it was felt to be difficult to insert a suction catheter deep down through a endotracheal tube which was placed for adequate ventilatory management. A three-dimensional chest CT revealed a vascular ring consisting of a double aortic arch. For 5 months following surgery, her respiratory symptoms have slowly been improving. She developed another episode of pneumonia which was milder than the one which occurred before the surgery.

To develop more specific and sensitive diagnostic methods for infectious bovine rhinotracheitis, 7-C-2 monoclonal antibody specific to polypeptides of infectious bovine rhinotracheitis virus (IBRV) was applied in indirect immunofluorescence antibody assay (IFA), indirect immunoperoxidase assay(IPA) and radial immunodiffusion enzyme assay (RIDEA). It was found that IBRV infected in MDBK cells could be detected as early as 8 hours post infection by IFA, and that IFA was more rapid and specific to identify IBRV antigen than IPA. The diagnostic efficacy of RIDEA and SN test was studied with 88 bovine sera. It was evident that RIDEA could eliminate the false positive reaction encountered in serum neutralization(SN) test, being more rapid and sensitive than the latter. Highly significant correlation coefficiency (r=0.76, p<0.01) was evaluated between the titers of sera and the diameters of RIDEA. Tracheal membranes and sera collected from 96 slaughtered cattle with lesions in respiratory organs were examined to detect IBRV antigen and antibody by IFA, RIDEA and SN test. It was presented that positive rates were 32.3% in IFA, 20.8% in RIDEA and 21.9% in SN test, and that coincidence rate between RIDEA and SN test were 100% in positive sera and 98.7% in negative sera. In conclusion, it was assumed that application of monoclonal antibody could improve the diagnostic efficacy of IBR by enhancing sensitivity and specificity of IPA, IFA and RIDEA.

전염성기관지염 바이러스(infectious bronchitis virus: IBV), 조류 뉴모 바이러스(Avian pneumovirus: APV), 뉴캣슬병 바이러스 (Newcastle disease virus: NDV), 조류인플루엔자 바이러스(avian influenza virus: AIV) 전염성 후두기관염 바이러스 (infectious laryngotracheitis virus: ILTV)는 닭의 호흡기에 직접 감염하여 호흡기질환을 일으키는 대표적인 바이러스로 알려져 있다. 그 밖에 아데노바이러스(adenovirus)와 레오바이러스 (reovirus)도 닭의 상부호흡기에 침투하여 피해를 입히는 이차적 원인체로 작용할 수 있다. 이들중 APV와 ILTV는 닭의 호흡기도에 국한되어 증식하지만 IBV, NDV, AIV의 경우 호흡기도 이외의 장기에서 증식이 가능하여 그 피해가 다양하게 나타나 문제 시 되기도 한다 (예: 산란장기 및 신장 (IBV), 소화기 (NDV, IBV, AIV), 중추신경계 (NDV, AIV)). 이외에도 상당수의 감염성 질환이 닭의 호흡기에 영향을 미칠 수 있으나, 해당 농장의 호흡기 피해가 어떤 질병에 의한 것인지 명확히 파악하지 못한 채 단순 항생제 처방에만 의지하는 경우가 많은 것이 현실이다. 따라서 국내 양계농가에서 문제시되는 주요 호흡기 질병과 이들의 감수성을 증대시키는 요인을 파악하는 것이 필요하고, 호흡기 질병의 피해에 대한 재인식과 아울러 호흡기 질병 피해 감소를 위한 진단과 예방노력이 하루속히 정착되어야 할 것이다. 본지에서는 대표적인 호흡기 질병 세가지(전염성기관지염, 조류뉴모바이러스감염증, 뉴캣슬병)의 최근 발생동향과 그 대처방안에 대하여 소개하고자 한다.
