In the past several years the popularity of the motor cycle has produced an increasing incidence of the injuries to the larynx and trachea. Most of all on accidents come to death and survivors to the hospital are rare. Early diagnosis and to keep air way are necessary to initiate proper treatment in injury of upper air way. Meticulous apposition of mucous membrane and reconstitution of laryngeal skeleton are important. We experienced a rare case of 26 year old men with cricothyroidal transection after trauma. On Oct. 17, 1985, the patient struck his neck on baggage frame of truck when dropping from his motor cycle on sudden stop. Emergency tracheal intubation on distal segment of trachea was accomplished by otolaryngologist in a local clinic. He was transferred to our hospital. Exploration 2 hours later revealed complete separation of cricoid cartilage from thyroid cartilage. The recurrent laryngeal nerve could not be identified. Anastomosis of thyroid and cricoid was accomplished and Portex endotracheal tube was inserted as splint for 10 days. No stenosis developed. The air way appeared adequate for moderate physical activity though paramedian fixation of vocal cord paralysis. Postoperative follow-up course has been good after he discharged on POD 14 days.

Laryngotracheal stenosis is one of the most troublesome diseases in the Em field. Subglottic stenosis can be treated by a cricoid augmentation with rib cartilage. In case of tracheal stenosis, the treatment of choice is by tracheal end-to-end anastomosis after resection of the stenotic site. However, in case of subglottic stenosis combined with tracheal stenosis, it is hard to manage. Even though several methods(such as thyrotracheal anastomosis) have been tried, they have some limitations too much excision of normal trachea and too much pulling up of the trachea after resection of the stenotic lesion. The authors have managed two cases of laryngotracheal stenosis as an anterior and posterior subglottic augmentation with an autologous cartilage graft and laryngotracheal anastomosis. The first few weeks after the operation, we could do a decannulation successfully, but in one case the patient developed restenosis. Even though one case was unsuccessful, the authors believe that this method could be used in the treatment of laryngotracheal stenosis.

Aspergillus infection is the most common cause of death due to fungi in immunocompromised hosts. Aspergillus tracheobronchitis is an uncommon but severe form of invasive pulmonary aspergillosis, which is limited entirely or mainly to the tracheobronchial tree and can often be life-threatening. We report a case of a 54-year-old man who died from Aspergillus tracheobronchitis without an underlying disease. Autopsy revealed an extensive yellowish plaque adhering to the trachea and bronchial wall. The microscopic examination of the trachea and bronchus revealed septate branching hyphae of Aspergillus.

Ninety-nine dogs diagnosed as tracheal collapse were reviewed for 2002-2003 year at Veterinary Medical Teaching Hospital, Seoul National University with clinical records and radiographs. Dogs were ranged in age from 1 to 15 years old (average 8.23 years old) and in weight from 1.2kg to 10.3kg (average 3.3kg). The population included 58 females (6 spayed) and 41 males (8 castrated). It is highly predominant in Yorkshire terrier (64, 64.6%) followed by Pomeranian (10, 10.1 %), Poodle and Chihuahua (8, 8.1%), Maltese (4, 4.0%), mixed breed (3, 3.0%), Cocker Spaniel and Pug (1, 1.0%). The incident rate of female dogs (59%) exhibited relatively higher than that of male dogs (41%). The most prevalent occurrence location was thoracic inlet (60%) of all and carina region (15%), intrathoracic trachea (14%) and cervical trachea (11 %) showed similar rate. Conclusively, tracheal collapse was observed in completely matured or old small breed dogs, largely Yorkshire terrier, on thoracic inlet primarily regardless of gender. These tendencies were apparently similar to previous reports.

The present study was performed to investigate the patterns of appearance of lectin in trachea of fetuses of 60, 90 and 120 days old and neonates of Korean native goat. Carbohydrate markers were used in histochemistry for the determination of the lectin by staining of avidin-biotin-peroxidase complex(ABC), and the markers consisted of biotin-labeled concanavalin A(Con A), dolichos biflorus agglutinin(DBA), rincinus communis agglutinin(RCA-I), ulexeuropalus communis agglutinin(UEA) and wheat germ agglutinin(WGA). 1. The Con A-binding reactions appeared moderately on the apical surface of the tracheal epithelia in 60 days old fetuses, and the reactions were similar on the tracheal epithelia and glands in 90 and 120 days old fetuses and neonates. 2. Reaction of the DBA appeared as the strongest meanwhile the DBA-binding reactions were determined strongly on the apical surface of the tracheal epithelia in the 60 days old fetuses. Reaction for the DBA on the tracheal epithelia and glands of 90 and 120 days old fetuses and neonates were in same manner. 3. The RCA-I-binding reactions appeared very strongly on the apical surface of the tracheal epithelia in 60 and 90 days old fetuses. Reaction to the RCA-1 appeared moderately on certain apical surface of tracheal epithelia and glands in 120 days old fetuses and neonates. 4. No reactions provoked for the UEA in trachea of 60 days old fetuses and neonates, but the UEA-binding reactions appeared moderately in the tracheal epithelia of 90 days old fetuses and weakly in 120 days old fetuses. 5. The WGA-binding reactions appeared very strongly on the apical surface of the tracheal epithelia in 60 and 90 days old fetuses, and moreover, the reactions were determined on the luminal surface of the tracheal gland in 90 days old fetuses. On the other hand, goblet cells of the tracheal epithelia and glands in neonates reacted moderately to the WGA.

Recently we reported that water extracts of Coptidis Rhizomas showed calcium antagonistic action and alpha-adrenoceptor inhibitory action in the vascular smooth muscle. Since ca lcium antagonistic properties are important in the treatment of various diseases including asthma. In the present study, the bronchodilatory effects of crude extract of three kinds of Coptidis Rhizoma (Coptidis chinensis, Coptis japonica and root hair of Coptis japonica) was investigated using rat isolated trachea. The result showed that all extracts relaxed carbachol-contracted tracheal smooth muscle. Concentration-dependently, in which the root hair of Coptis japonica was the least potent. The inhibitory potency expressed in terms of $IC_{50}$ against carbachol contraction was 1.8${\mu}$g/ml and 2.7${\mu}$g/ml for Coptidis chinensis and Coptis japonica, respectively. These extracts also inhibited KCI-contracted tracheal smooth muscle. But the relative potency ($IC_{50}$) was 3.5 and 4.1 folds weaker than carbachol-induced contraction for Coptidics chinenesis and Coptis japonica, respectively. Pretreatment of crude extracts also inhibited carbachol- or KCI-induced contraction, non-competitively. These findings indicate that the extracts have muscarinic blocking as well as $Ca^{2+}$ channel blocking action. When provoked intracellular stored $Ca^{2+}$ release by carbachol in $Ca^{2+}$-free conditions, initial phasic contraction due to $Ca^{2+}$ release was significantly inhibited by the extracts. As taken together, we conclude that water extracts of Coptidis Rhizoma may be beneficial in bronchospasm or other broncheal tube narrowing conditions such as asthma.

Mucormycosis is the common name given to several different diseases caused by fungi of the order Mucorales. The mucoraceae are ubiquitous fungi and are common inhabitants of decaying matter. In contrast to the widespread distribution of these fungi, disease in humans is limited, in most cases, to people with severe immunocompromised, diabetes mellitus, or trauma. 1be fungus gains entry to the body through the respiratory tract. The spores are presumably deposited in the nasal turbinates and may be inhaled into the pulmonary alveoli. The manifestations of mucormycosis are rhinocerebral, pulmonary, cutaneous, gastrointestinal, central nervous system, and miscellaneous. Sporadic reports can be found of mucormycosis involving other areas : heart, bones, kidney, bladder, mediastinum, and trachea. However, isolated tracheal mucormycosis is very rare. Therefore, we report a 57-year old, noninsulin dependent diabetic woman who presented with acute, severe degree of upper airway obstruction due to isolated mucormycosis of the trachea.

Purpose: Traumatic airway injuries have high rates of mortality and morbidity. Thus, we evaluated the clinical results of trauma-related airway-injury patients. Methods: A clinical analysis was performed for patients with airway trauma who were admitted and treated at the Department of Thoracic and Cardiovascular Surgery, Konyang University Hospital from Dec. 2002 to Dec. 2009. Results: Sixteen patients were admitted and treated. Fourteen patients were male, and the ages of the patients ranged from 16 to 75 years. Six cases were penetrating injuries, 4 were traffic-accident injuries. 3 were fall injuries, and. 3 were other blunt trauma injuries. Anato- mic injuries included 14 trachea cases (87.5%), 1 Rt. main bronchus (6.25%), and 1 Lt. main bronchus cases (6.25%). Diagnosis was made by using computed tomography and bronchoscopy. Five patients were treated with an explothoracotomy, and 7 underwent neck exploration with primary repair. Three patients simply needed conservative management, and 1 patient was treated with a closed thoracostomy. The post-operative mortality rate was 6.25 % (1 patient). Conclusion: Airway trauma is dangerous and should be treated as an emergency, so a high index of suspicion is essential for rapid diagnosis and successful surgical intervention in patients with airway injuries.

Penetrating neck trauma by gunshot injury involving tracheobronchial tree is rare in Korea. Extensive tissue damage by cavitation, tissue fragmentation and shock wave transmission of high-velocity projectile along with associated organ injury renders high rate of mortality and morbidity. A 28 year old man in military service with gunshot wound in left cervical area presented initial symptoms of severe dyspnea and subcutaneous emphysema. Computed tomography of chest and cervical region as well as bronchoscopic evaluation was performed to confirm highly suspected injury to cervical trachea. Surgical exposure was established through a low collar incision; the damaged segment of 3.5 cm length including 2-4th tracheal rings was resected out and end-to-end anastomosis was performed. Bleeding from lacerated anterior jugular vein was controlled by ligation of both ends and a K2 bulllet was found upon inner border of body of first rib, medial to right carotid sheath and removed out. Cervical esophagus, carotid artery, internal jugular vein and recurrent laryngeal nerve were spared. Extubation was done on the first postoperative day and postoperative course until discharge on nineth postoperative day remained uneventful.
