The foreign bodies in air way require the emergent managements in the otolaryngolagic field, and if the diagnosis and treatment were delayed, unexperted catastrophic situations may occur. The authors had analysed the airway foreign bodies of 50 cases which had been ventilating bronchoscopy. 1. In sex distribution, male to female ratio was 2.8 : 1. 2. In the age incidence, 58% were 1∼5 yrs. 3. Frequent symptoms, were coughing (68%), dyspnea (52%) and cyanosis (18%) in the oder. 4. The significant foreign body histories were noticed in 33 cases (66%). The initial misdignosis were 28%, and af which 57.1% were URI 5. In auscultation, decreased breathing sounds were noticed in 46%, wheezing were 24% and 26% were with in normal limit. 6, In duration af lodgement, 68% were removed within 24 hours. 7. Tracheostomy were performed in 24%, and foreign bodies were removed by ventilating bronchoscope in 72%. 8. The foreign bodies were vegetable (46%), metal (28%), plastic (18%) and fish bone (8%). 9. The prevalent site of foreign body were right main bronchus, left main bronchus, and trachea in the order mentioned.

1983년 10월에 15세된 여자가 내원 수일 전부터 오른쪽 눈의 이물감과 소양증을 주소로 내원하였다. 며칠전 환자 자신이 오른쪽 눈에서 충체를 꺼냈으며, 내원하여 2마리를 적출하였다. 두 마리는 모두 자충이었으며 각각 길이 13.4mm, 폭 0.36mm와 길이 8.3mm, 폭 0.39mm였으며 구강의 길이는 각각 0.24mm, 0.31mm이었다. 표피의 가로주름이 식도부위에서는 1mm당 281개, 중앙부위는 172개, 후단부는 162개이었으며 충체 전단부터 질 입구까지의 길이는 0.44mm이었다. 이상의 소견으로 두마리 충체를 Thelazia callipaeda로 동정하였다. 이 동양안충 감염에는 한국에서 15번째이다.

A clinical study was done on 24 cases with foreign body in the air passage, who were treated at the department of otolaryngology of Kyung Hee university hospital during the period from Apr. 1973 to Feb. 1983. The obtained results were as follows : 1) The incidence of sex was much higher in male than female and children under 4 years old were predominant. 2) Almost of all patients came in the hospital within 3 days after onset. However one patient came in hospital 5 months later. 3) The variety of foreign body was numerous, among which vegetables and plastic materials were most frequently found. 4) The most common sites of lodgement were trachea and right main bronchus. 5) The common clinical manifestations were dyspnea, decreasing breathing sound and cough. Negative X-ray findings did not exclude a foreign body in the air passage. 6) The important pulmonary complications due to foreign body were atelectasis, emphysema and pneumonia. 7) Foreign body was successfully removed by use of peroral or inferior endoscopy in all cases except one case, on whom thorachotomy was done. 8) The important complications due to the surgical procedure were decannulation difficulty and pneumothorax.

연두금파리 종령유충의 복강내에 이물질로서 protein-A gold 용액(20 nm 크기) colloidal gold 용액(15 nm 크기), 그리고 이들의 혼합액을 주입하여 혈구가 이들을 처리하는 양상을 전자현미경을 이용하여 관찰하였다. Gold 입자에 대한 혈구의 세포성 면역작용 방식은 식세포작용이었고 이러한 식세포 작용은 연두금파리에서 확인한 prohemocyte, plasmatocyte. granulocyte type I, II, III, 그리고 oneocvtoid 등의 6가지 혈구 중 type 11 granulocyte에 의해서 수행되었다. Gold 입자는 주로 판상의 원형질 돌기를 통하여 혈구 속으로 들어갔으며 coated-pit로 보이는 구조에 의해서도 받아들이는 것으로 나타났다. 식세포 작용은 gold 용액 주입후 10분 이내에 빠른 속도로 일어났으며 시간이 경과함에 따라 gold 입자를 함유한 phagosome은 리소소음과 융합하여 phagolysosome을 형성하면서 세포질내에 축적되어 있었다. Gold 용액을 주입한 후 type II granulocyte에서는 세포질 돌기와 전자 밀도가 높은 과립, 그리고 세포 소기관이 소실되는 등의 변화가 일어났다. protein A-gold 및 colloidal gold 용액에 대한 기본적인 식세포 과정은 별다른 차이점이 없었으나 gold 입자 섭취 초기 과정과 양, 그리고 multivesicular body의 모습등에서는 차이점을 보여 주었다.

Compared with other medical parts, there are relatively rare cases of the calculi in the Otolaryngologic field. The authors have recently experienced cases of the tonsillolith and huge rhinolith. They were removed successfully under the local anesthesia. Small quantities of calcareous or gritty particles are often found in the center of the caseous plugs filling the crypts of the tonsil in chronic follicular tonsillitis. The patients usually give a history of repeated tonsillitis in the earlier years. The patient may be aware of a constant sensation as of a foreign body in the throat. The breath is often fetid. The tonsillar calculi was found to be the accumulated keratohyalin masses in the crypts. The rhinoliths are rare in nasal cavity. They usualy have a foreign body nucleus of bacteria, blood, pus cells, mucus, crusts, or some foreign material from outside the body. They are largely composed of calcium and magnesium salts, principally carbonate with traces of sodium chloride. The condition is commonly found in adults and in female. They are usualy unilateral and are located, in the majority of instances, in the lower portion of the nasal cavity. The first well documented cases of rhinolithiasis, however, were reported by Bartholin in 1654. Since then over 400 cases have been reported.

A 1.6-year-old, intact male beagle dog was presented with three day history of odynophagia and anorexia. According to the history and radiographic findings, the patient was diagnosed with esophageal and gastric foreign body due to ingesting fishhooks. Gastroesophagoscopy revealed that one fishhook located in the thoracic esophagus cranial to the heart base and the other located in the cardia region were connected with a single fishing line. Gastrotomy was performed to remove the fishhook in the cardia region and to sever the connecting fishing line. After gastrotomy, endoscopic attempts to remove the esophageal fishhook with a three, five pronged endoscopic grasping forceps, and a biopsy were unsuccessful because the fishhook was embedded deeply in the mucosa membrane. A handmade cerclage wire(16G) shaped like a snare forceps was advanced into the esophagus while visualizing the fishhook endoscopically. The cerclage wire was used to hang and retract the foreign body. The fishhook was retracted orally, resulting in successful removal. Ten days after the operation, the patient fully recovered and was discharged.

일반적으로 집이나 건물이 지어진 후 약 2~3년이 지나면 수도관 내부에는 물때, 미생물, 유기화합물질 등이 혼합되어 슬라임(slime)이 발생하며, 노후화되어 슬러지(sludge) 형태로 누적 되거나 스케일(scale)이 발생하고 있다. 이러한 이물질의 누적으로 인하여 수도관이 손상되거나, 여러 가지 원인으로 인하여 교체해야하는 상황이 발생할 수 있다. 이러한 이유로 저수조나 공용관의 경우에는 정기적으로 세척하고 있으며, 일반 가정 내의 수도관 역시 정기적인 관리가 필요하다고 볼 수 있다. 본 논문에서는 적절한 배관청소기의 제어를 위하여 물과 압축공기의 배합을 적절하게 제어하도록 하여 배관내부의 이물질을 제거할 수 있는 배관청소시스템을 설계하고자 하며, 밸브조절 및 물의 공급시간과 압축공기의 유입시간에 대한 적절한 제어를 원격지에서 제어할 수 있도록 배관청소시스템을 개발하여 성능에 관한 평가와 사업화 가능성을 제시하고자 한다.

Laryngeal foreign bodies are not common among the foreign bodies of aerodigestive tract. It is relatively easy to diagnose in acute phase of entry because of a readily\ulcorner available history of intake, and signs or symptoms referable to the foreign body in the highly sensitive air passage. However, on occasion, sudden death by respiratory failure occurs due to complete obstruction of airway. Therefore, it is common and safe to remove the laryngeal foreign bodies by suspension laryngoscope under general anesthesia after tracheostomy. Recently, the authors experienced a case of metallic foreign body in larynx penetrating neck, which was removed by suspension laryngoscope under general anesthesia without any life threatening complication.

Occult bronchial foreign body is that long-standing foreign body lodge in bronchial tree. Occult bronchial foreign bodies arc rare in adults, whereas tracheobronchial aspiration of foreign bodies occurs commonly in children. A 65-year-old man with chronic cough, sputum production, and fever was transferred for treatment of right middle and lower lobc collapse and obstructive pneumonitis as evidenced by imaging studies. The patient was treated with right middle-lower bilobectomy because fiberoptic bronchoscopic removal of the foreign body failed. We report this case with review of literatures.

Authors experienced a bronchial foreign body-an injection needle at the proximal portion of reft main bronchus of a 5 years old female child. An interesting dynamic problem encountered during the removal. A human bronchial specimen lodging the foreign body will be demonstrated with consideration of the dynamic factors.
