Foreign bodies in food and air passage, especially the latter in infants and children requires emergency treatment. The frequent symptoms are coughing, wheezing, and dyspnea, So may be confused as asthma, pneumonia and acute Laryngitis. The species and incidence of the foregin bodies are variable according to the age, method of life, environment and economic condition. The authors experienced 35 cases of foreign body in air passage during the period of last 3yrs which were treated by ventilating Bronchoscopy, and thoractomy in this hospital. One of them was lead to death. The authors analysed above cases and report with it's literature consideration. Results: 1. The prevalent foreign bodies were peanut, metal, food particles in order of frequency. 2. In frequent symptoms were dyspnea, coughing and wheezing in the order. 3. In the age incidence, 48% of the foreign bodies were 1∼5yrs. 4. In sex distribution, male to female ratio was 2.1: 1 5. In duration of lodgment, 65% of the foreign body were removed within 24hrs. 6. Most prevalent site of the foreign body was Rt. main bronchus Rt. to Lt. ratis was 2 : 1 was 7. Treatment was done; 25 cases were by ventilating bronchoscopy.

The clinical entity referred to as epithelial hyperplasia has been called by various terms : keratosis, hyperkeratosis, pachydermia, acanthosis, leukoplakia, hyperkeratotic laryngitis. The metaplasia and keratinization of the layngeal mucosa are associated with the subsequent appearance of invasive epidermoid carcinoma. Therefore. frequent and prolonged periods of observation and histologic study on keratosis of the larynx are essential. A retrospective review of 18 patients with laryngeal hyperkeratosis seen at Department of Otolaryngology Yondong Severance Hospital during the 7 years period was completed. The results are summarized as follows : 1) The incidence was much higher in males(22 patients) than in females(4 patients) 2) The peak age of male was 4th decades and the peak age of female was 4th. 5th decades. 3) The chief complaint of the patients was hoarseness in all cases. 4) The average duration of symptoms was less than 24 months for 19 cases(73.1%). 5) 17 patients(65.4%) was smokers and duration of smoking was 10~20 years for 10 cases(38.8%). 6) On histological examination. the lesions were classified into three types: simple hyperplasia(61.5%). dysplasia(26.9%) and carcinoma in situ(2 cases). 7) The recurrence rates was 9 cases(34.6%) and transformation rate into invasive carcinoma was 1 case(3.8%).

Dioscorea bulbifera is one of the traditional medicinal herb. It commonly used in the treatment of hematemesis, epistaxis, tuberculous cervical lymphadenitis, laryngitis, acute infectious disease in East Asia. In the present study, we have demonstrated the anti-inflammatory effects of Dioscorea bulbifera MeOH extract (DBME) in macrophage cell line. To investigate mechanism of the anti-inflammatory activity, we examined the effects of the lipopolysaccaride (LPS)-induced production of nitric oxide (NO), prostaglandin $E_2$ ($PGE_2$), pro-inflammatory cytokines and expression of inducible NO synthase (iNOS), cyclooxygenase-2 (COX-2), p-inhibitory ${\kappa}B{\alpha}$ (p-$I{\kappa}B{\alpha}$), and nuclear factor-${\kappa}B$ (NF-${\kappa}B$) in a murine macrophage cell line RAW 264.7. The RAW 264.7 cells were cultured in DMEM + serum medium for 24 hrs. After serum starvation for 24 hrs, the cells were treated with DBME 0.03, 0.10, 0.30 mg/$m{\ell}$ for 1 h, followed by stimulation with LPS (1 ${\mu}g/m{\ell}$) for activation of immune response. After treatment, cell viability was measured by MTT assay, and NO production was monitored by measuring the nitrite content in culture medium. The protein band of iNOS, COX-2, p-$I{\kappa}B{\alpha}$, and NF-${\kappa}B$ was determined by immunoblot analysis and levels of cytokine were analyzed by sandwich immunoassays. There were three experimental groups: carrageenan, DBME 0.3, 1.0 g/kg. Rats were administrated either carrageenan (40% PEG) or carrageenan + DBME (0.3, 1.0 g/kg body weight) for 4 days (p.o.). To induce acute paw edema, rats were injected 1% carrageenan (100 ${\mu}{\ell}$/rat, dissolved in sterilized saline). The effect of DBME in the carrageenan-induced rat paw edema. As results, DBME has an inhibitory effect on the production of NO, PGE2, TNF-${\alpha}$, IL-$1{\beta}$ and IL-6 and on the expression of iNOS, COX-2, p-$I{\kappa}B{\alpha}$ and translocation of NF-${\kappa}B$ to nuclear from cytosol. In addition, DBME effectively inhibited the increases of paw edema induced by carrageenan treatment in vivo. These results suggest that DBME can inhibit production of pro-inflammatory mediators and might be a useful source for treatment of acute inflammatory disease.

The major advancement in phonosurgery due to recent development of laryngomicrosurgery enabled more accurate diagnosis and treatment of patient with voice disorders. Among large proportion of voice disordered patients, prominent linear furrow running parallel along the free edge of vocal cord extending from the vocal process to anterior commissure can be seen as well as incomplete closure during phonation. These cases were illustrated and coined as sulcus vocalis by Salvi in 1901, since then other similar paper was reported in Europe and Japan, but has not been reported in Korea. The exact etiology and therapeutic methods of sulcus vocalis has not been elaborated. At Department of Otolaryngology of Yonsei University College of Medicine a series of voice analysis were performed among those 35 patients with sulcus vocalis visited to Vocal Dynamics Laboratory from May, 1981 to March, 1982. Following is the result of clinical statistical investgation and therapeutic modality. 1) The incidance of sulcus vocalis among 290 patients with voice disorder visited to Vocal Dynamics Laboratory was approximately 12%(35 cases). 2) Onset of this voice disorder was most frequent among patient under 10 year-old groups; 19 cases (54%) followed by second decade, third decade groups in decreasing frequency respectably. 3) The etiology of sulcus vocalis was mostly unknown. The sequelae after measle (4 cases) and severe upper respiratory infection (3 cases) and congenital deformity (2 cases) were the possible causes of sulcus vocalis. 4) These patients were involved bilaterally in 25 cases (71%), left side only in 8 cases (23%) and right side only in 2 cases (6%). 5) Almost all patients complained hoarseness and 7 patients were suffering from chronic laryngitis. 6) In aerodynamic analysis, Maximal Phonation Time was decreased in 20 cases (57%), Phonation Quotient was increased in 22 cases (63%) and Mean Air Flow Rate was increased in 23 cases (66%). 7) Among them, 33 cases were analyzed with stroboscopy. The findings were as follows; incomplete glottic closure during phonation in 31 cases (93%), regular vocal cord movement in whole cases, asymmetric cord movement in 4 cases (12%), decreased amplitude in 5 cases (21%) and small mucosal wave in 24 cases (73%). 8) Intracordal Teflon injection in 5 cases and Sulcusectomy in 1 cases were performed as therapeutic management, however, the therapeutic results were not effective except one case with Teflon injection.

Bronchoalveolar lavage had been done as the treatment of some diseases such as alveolar proteinsois, bronchiectasis, and severe asthma to remove excessive secretion or mucus. But in the recent decade it has been done as a diagnostic method and a tool to understand and evaluate the pathophysiology of diffuse interstitial lung diseases such as sarcoidosis, pneumoconiosis and hypersensitivity pneumonitis. To analyse the bronchoalveolar fluid, it might be useful to have a standard reference (especially cell counts and differetial count of the cells from bronchoalveolar lavage fluid) of normal person. But it is difficult to study the normal volunteers. We investgated the bronchoalveolar lavage fluid of 48 patients (28 nonsmokers, 20 smokers) who visited Severance Hospital because of minor pulmonary symptoms such as cough and sputum. They did neither complain of dyspnea nor cyanosis, and had normal or unilateral minor lesion on physical examination and chest X-ray. We analysed the recovery rate, viability, total cell count and differential count of the cells in fluid obtained by bronchoalveolar lavage. The following results were obtained: 1) Age ranged from 17 to 72 years-old with the mean age of 36.7; there was no difference of age between the nonsmoker and the smoker gorup. Male to female ratio was 2.43:1 for total group, 1.15:1 for nonsmokers, and 19:1 for smokers. 2) The diagnoses of the patients were undetermined in 41.9%, healed pulmonary tuberculosis in 37.5%, laryngitis or pharyngitis in 10.4% and others in 10.4%. 3) Total cell number of the recovered fluid by bronchoalveolar lavage was significantly higher in male[$9.6{\pm}6.2({\times}10^6)$] than in female[$5.1{\pm}3.0({\times}10^6)$](p<0.05), and there was no significant difference in the total cell number between the smokers and nonsmokers [$9.3{\pm}5.8({\times}10^6)$ vs $7.5{\pm}5.8({\times}10^6)$]. 4) The differential count of the cells from bronchoalveolar lavage fluid had no difference between the nonsmokers and the smokers. 5) There was no correlation between the total cell count and smoking or age. 6) In the smoker group, there was no correlation between the amount of smoking and the total cell count of the bronchoalveolar fluid. In conclusion, it should be careful to regard the patients with symptoms or minor radiologic abnormalities as a control group in bronchoalveolar lavage study and further study of cell analysis in bronchoalveolar lavage will be needed between smoker and nonsmoker in the male and female healthy people.

Lonicerae Flos has antibacterial effects against Staphylococcus aureus, streptococci, pneumococci, Bacillus dysenterii, Salmonella typhi, and paratyphoid. It is an antiviral agent. The herb has a cytoprotective effect against $CCl_{4}-induced$ hepatic injury. It has antilipemic action, interfering with lipid absorption from the gut. Nowadays this herb is used mainly in the treatment of upper respiratory infections, such as tonsillitis and acute laryngitis. It is also used in the treatment of skin suppurations, such as carbuncles, and to treat viral conjunctivitis, influenza, pneumonia, and mastitis. Lonicerae Flos is dried flower buds of Lonicera japonica, L. hypoglauca, L. confusa, or L. dasystyla. But, for the most part, we use whole plant of Lonicera japonica, as a flower bud of it. And, little is known of the original copy of effects of whole plant, except for the 'Bon-Cho-Gang-Mok', which is written the effects of flower of Lonicera japonica are equal to effects of leaves and branch of it. The present study was conducted to evaluate the effect of flower and whole plant of Lonicera japonica on the regulatory mechanism of cytokines, inducible nitric oxide synthase (iNOS) and cyclooxygenase (COX-2) for the immunological activities in Raw 264.7 cells. In Raw 264.7 cells stimulated with lipopolysaccharide (LPS) to mimic inflammation, flower and whole plant of Lonicera japonica water extracts inhibited nitric oxide production in a dose-dependent manner and abrogated iNOS and COX-2. Flower and whole plant of Lonicera japonica water extract did not affect on cell viability. To investigate the mechanism by which flower and whole plant of Lonicera japonica water extract inhibits iNOS and COX-2 gene expression, we examined the on phosphorylation of inhibitor ${\kappa}B{\alpha}$ and assessed production of $TNF-{\alpha}$, $interleukin-1{\beta}$ $(IL-1{\beta})$ and interleukin-6 (IL-6). Results provided evidence that flower and whole plant of Lonicera japonica inhibited the production of $IL-1{\beta}$, IL-6 and activated the phosphorylation of inhibitor ${\kappa}B{\alpha}$ in Raw 264.7 cells activated with LPS. These findings suggest that flower and whole plant of Lonicera japonica can produce anti-inflammatory effect, which may play a role in adjunctive therapy in Gram-negative bacterial infections, respectively.

The air pollutants can be classified into the irritant gas and the asphixation gas, and the irritant gas is closely related to the otorhinolaryngological diseases. The common irritant gases are nitrogen oxides, sulfur oxides, hydrogen carbon compounds, and the potent and irritating PAN (peroxy acyl nitrate) which is secondarily liberated from photosynthesis. Those gases adhers to the mucous membrane to result in ulceration and secondary infection due to their potent oxidizing power. 1. Sulfur dioxide gas Sulfur dioxide gas has the typical characteristics of the air pollutants. Because of its high solubility it gets easily absorbed in the respiratory tract, when the symptoms and signs by irritation become manifested initially and later the resistance in the respiratory tract brings central about pulmonary edema and respiratory paralysis of origin. Chronic exposure to the gas leads to rhinitis, pharyngitis, laryngitis, and olfactory or gustatory disturbances. 2. Carbon monoxide Toxicity of carbon monoxide is due to its deprivation of the oxygen carrying capacity of the hemoglobin. The degree of the carbon monoxide intoxication varies according to its concentration and the duration of inhalation. It starts with headache, vertigo, nausea, vomiting and tinnitus, which can progress to respiratory difficulty, muscular laxity, syncope, and coma leading to death. 3. Nitrogen dioxide Nitrogen dioxide causes respiratory disturbances by formation of methemoglobin. In acute poisoning, it can cause pulmonary congestion, pulmonary edema, bronchitis, and pneumonia due to its strong irritation on the eyes and the nose. In chronic poisoning, it causes chronic pulmonary fibrosis and pulmonary edema. 4. Ozone It has offending irritating odor, and causes dryness of na sopharyngolaryngeal mucosa, headache and depressed pulmonary function which may eventually lead to pulmonary congestion or edema. 5. Smog The most outstanding incident of the smog occurred in London from December 5 through 8, 1952, because of which the mortality of the respiratory diseases increased fourfold. The smog was thought to be due to the smoke produced by incomplete combustion and its byproduct the sulfur oxides, and the dust was thought to play the secondary role. In new sense, hazardous is the photochemical smog which is produced by combination of light energy and the hydrocarbons and oxidant in the air. The Yonsei University Institute for Environmental :pollution Research launched a project to determine the relationship between the pollution and the medical, ophthalmological and rhinopharyngological disorders. The students (469) of the "S" Technical School in the most heavily polluted area in Pusan (Uham Dong district) were compared with those (345) of "K" High School in the less polluted area. The investigated group had those with subjective symptoms twice as much as the control group, 22.6% (106) in investigated group and 11.3% (39) in the control group. Among those symptomatic students of the investigated group. There were 29 with respiratory symptoms (29%), 22 with eye symptoms (21%), 50 with stuffy nose and rhinorrhea (47%), and 5 with sore thorat (5%), which revealed that more than half the students (52%) had subjective symptoms of the rhinopharyngological aspects. Physical examination revealed that the investigated group had more number of students with signs than those of the control group by 10%, 180 (38.4%) versus 99 (28.8%). Among the preceding 180 students of the investigated group, there were 8 with eye diseases (44%), 1 with respiratory disease (0.6%), 97 with rhinitis (54%), and 74 with pharyngotonsillitis (41%) which means that 95% of them had rharygoical diseases. The preceding data revealed that the otolaryngological diseases are conspicuously outnumbered in the heavily polluted area, and that there must be very close relationship between the air pollution and the otolaryngological diseases, and the anti-pollution measure is urgently needed.
