  • Allergic contact dermatitis (skin sensitization) may be caused by a wide variety of chemicals. A murine local lymph node assay (LLNA) has been developed as an alternative to guinea pig models for assessing the contact sensitization potential of chemical. This study was carried out to evaluate the skin sensitization potential for chemicals in Balb/c mice by LLNA. Contact allergen, dinitrochlorobenzene (DNCB), respiratory allergen, toluene diisocyanate (TDI) and a weak allergen, $\alpha$-hexlycinnamaldehyde (HCA) were wed as positive chemicals and irritant, sodium lauryl sulfate(SLS) also wed as a reference chemical in this study. The weights of lymph node in the mice treated with DNCB, TDI, and HCA were increased compared to vehicle control. There was a significant increase in lymph node weight of mice treated with high concentration of SLS compared to vehicle control. The stimulation index (SI) of Lymph node cell in the mice treated with DNCB, TDI, and HCA revealed over three-fold increase compared to vehicle control by $3^H$-thymidine uptake. All allergens correctly identified in this LLNA study wing Balb/c mice. These results suggest that LLNA wing Balb/c mice could be a useful method for screening the allergenic potential of chemicals. The expression of IL-2 mRNA was slightly increased in draining auricular lymph node cell of the mice treated with TDI and HCA by RT-PCR. However the IL-2 levels in DNCB and SLS of treated animals were not significantly changed.

  • Hwamunsok(mat with flower design) is a special product of Kanghwa, which is made up of cyperus exaltatus. According to Allergy, cyperus exaltatus is one of the inhalant allergens and provokes respiratory symptoms and signs. There have been few reports about respiratory allergic disease or contact dermatitis occurring in farmers who cultivate the cyperus exaltatus or manufacture Hwamunsok with it. We studied the relationship between allergic symptoms and exposure to cyperus exaltatus. First, we questioned 141 voluntaries living in Kangwha on the symptoms of contact dermatitis, allergic rhinitis and bronchial asthma. Secondly, open tests with cyperus exaltatus were done to permitted 73 voluntaries. Patch tests with the European standard series(23 antigens) were only done to exposure 49 subjects to cyperus exaltatus. The results were as follows : 1. As the manifestation rate of allergic symptoms by age, its of 60 years old over in male showed 333 per 1,000 persons. Its of 50 years old in female showed 412 per 1,000 persons. Those age groups in both genders exhibited the highest manifestation of allergic symptoms than all other age groups. Also, if age and sex were adjusted with the rural population of Kanghwagun('93 base population), the manifestation rate of allergic symptoms in male showed 283 per 1,000 persons. Its in female and totals of study populations showed which is each 206 and 234 per 1,000 persons. Specially, it showed that statistics significantly(p=0.002), exposured subjects by cultivation of cyperus exaltatus & manufacture of Hwamunsok have experienced symptoms of contact dermatitis more frequently than unexposured subjects. Secondly, it tested statistics significantly that the risk factor as manifestation of allergic symptoms was the exposure of cyperus exaltatus's allergen(p=0.024). The manifestation risk of allergic symptoms in exposure groups was 3.73 times higher than unexposured subjects. Thirdly, positive reactions in open tests with cyperus exaltatus were higher in exposured subjects than non-exposured subjects. After 72 and 96 hours, positive reactions in open tests were all 10 subjects(20.4%). Also, after 1 week, positive reactions were 8 subjects(16.4%). In conclusion there is a close relationship between contact dermatitis and exposure to cyperus exaltatus while cultivating it and manufacturing Hwamunsok. Therefore, various studies should be continued and a health education program undertaken on contact dermatitis with those who were be engaging in Hwamunsok's manufacture.

  • Allergic disorders may be defined as the abnormal reactions to proteins. Cow milk is the first foreign protein which the human being would contact postnatally. Serveral studies suggested that this contact had certain effects on the development o allergic disorders with great controlversies. Seven hundred seventy eight students from middle class in Seoul, aged 6 to 17 wears, were surveyed to delineate the relationshpis between the cow's milk contacts in infancy and the subsequent development of allergic disorders in Koran population. Questionaire were included the nursing patterns in infancy, the past medical history of asthma or wheezy bronchitis and the presence of infantile eczema. Skin tests to three common resporatory allergens in Korea(house dust, house dust mite; D. farinae, D. ptoeronssinus) were performed. The positivity was determined by the wheal size larger than that to histamine. 70.2% of whole mateials was fed by breast milk, 13.1% by cow's milk and 16.7% by mixed nutsing. From the obsevation of nursing patterns by (table 2), we find that the number of breast milk group has been decreasing in 1970's. 10.1% of breast milk group(BMG) had wheezy bronchitis, 8.8% of cow's milk group(CMG) and 11.5% of mixed nursing group(MNG). Infantile eczema history was positive in 27.8% of BMG, in 26.5% of CMG and in 29% of MNG. Skin test positivity was 23.8% in BMG, 25.5% in CMG and 26.2% in MNG. There prevalences of allergic disorders in each nursing group did not reveal any statistically significant differences. In conclusion, nursing patterns in infancy do not seem to have certain effects on the development of allergic disorders such as infantile eczema. wheezv bronchitis or skin test positivity.

  • The Langerhans cells are dendritic nonkeratinocytes found suprabasally in most stratified squamous epithelia, such as human epidermis and the epithelium of the oral mucosa including that of gingiva. After Paul Langerhans found it in the skin in 1968, there have been sturdies of it's function and distribution . Stingle et al. reported that the Langerhans cells seem able to present antigens and to stimulate T-lymphocytes. Shelley et al. discovered that they can take up contact allergens. Accordingly it has been suggested that Langerhans cells are important elements of p Peripheral cell mediated immune system. In this study, the gingival tissue of a adult periodontitis patient was taken and freeze dried. In one specimen, we used the CD1 monoclonal antbody to staining the Langerhans cell. The other specimen, we embedded in paraffin and staining it with S-100 monoclonal antibody. The purpose of this study was to use these specimens to find out the distribution, orientation, morphology of the Langerhans cell and to discover the increase or decrease of Langerhans cell in an increased inflammatory state. The results were obtained as follows : 1. Langerhans cells were distributed between the basal cell layer and spinous cell layer against the CD1 & S-100 monoclonal antibody. 2. Langerhans cessl were plentiful in the oral eptihelium, and there was very little in the sulcular epithelium. 3. There were no Langerhans cell in the junction epithelium and pocket lining epithelium. 4. The number of Langerhans cells that responsed to the CD1 & S-100 monoclonal antibody had a statistically difference. 5. As the infiltration of the lymphocyte into the connective tissue were increased, the number of Langerhans cells in the epithelium were increased. 6. As the inflammation was increased, Langerhans cells in the spinous cell layer were more increased than those of the basal layer.

  • The Rhus verniciflua contains alkly(en)-catechol type allergens with a saiurated or unsaturated alkly chain of 15 or 17 carbon atoms. It has been recognized as an extremely active allergen causing skin reactions similar In poison ivy. The allergic contact dermatitis induced by the urushiol is known to be mediated be T lymphocytes whicht specifically recognize the hepten urushiol. Therefore. direct use of this plant as a medicinal purpose might imply a considerable hazard in Korea. In this study, using the established method for the detoxification from the stem bark of Rhus verniciflua, an strong antioxidant substance was isolated and characterized DPPH (diphenypricryl hydrazyl) assay measures hydrogen atom-donating activity and hence provides a measure of free radical scavenging antioxidant activity. DPPH, a purple-colored stable free radical, is reduced to yellow-colored diphenylpicryl hydrazine by antioxidants to deducing agents. Antioxidative effects of the water extract from RV were measured by DPPH assay. Twenty microliters of the extract was added to 1ml of 100mM DPPH solution in ethanol The mixture was shaken and left to stand for 10min at room temperature. The crude water extracts was purified by using HPLC method with a DEAE (anionic type), CN, ODS column. The purified compound remained stable at pH 3.0-6,0, but unstable above pH 6.5. It was stable heat at 10$0^{\circ}C$ for 4 hours, but still had about 80% of residual activity after treatment at 10$0^{\circ}C$ for 5 hours. The elemental composition of the HR-EI mass spectrum at m/z 170.02 was estimated the empirical formula as $C_{7}$ $H_{6}$ $O_{5}$. $C_{10}$ $H_4$ $O_2$N$_1$, $C_{5}$ $H_4$ $O_4$N$_3$, $C_{8}$$H_2O$$_1$N$_4$. In antimicrobial test, no inhibition was observed against Gram-positive and negative bacteria. This compound was stronger than that of commercial antioxidant by DPPH test, such as BHT, BHC at the same concentration (20$\mu$g/ml).ml).

  • In dentistry, precious metal alloys are, mainly due to economic factors, increasingly displaced by alternatives containing Ni-Cr-Co. There are some reports where hypersensitive reactions to Ni-Cr-Co alloys are presented and discussed. The reactions reported vary from mucosa contact stomatitis to generalized dermatitis without any oral mucosal reaction. The purpose of this study was to investigate the incidence of nickel, chrome, cobalt and copper, and to know whether subjects with positive skin reaction to nickel would also demonstrate adverse intraoral reaction to a non-precious metal nickel. The patch tests were performed in 81 subjects(male 39, female 42) and nickel sulfate 5% aq., potassium bichromate 0.5% at., cobalt chloride 2% aq., & copper sulfate 1% aq., were used for test allergens. And then the intraoral tests were performed in 16 subjects, 8 subjects with positive allergic skin reaction to nickel and 8 subjects with negative allergic skin reaction. A pure metallic nickel plate was attached to the buccal side of the upper second premolar. The results are as follows : 1. The frequency of nickel sensitivity was 9.9% (2 men, 6 women), cobalt was 4.9% (1 man, 3 women), and chrome was 2.5% (2 men) respectively and there was no positive reaction to copper 2. The positive reactions were 8 of 23 (34.8%) with a history of jewelry allergic reactions and 3 of 58 (5.1%) without a history of jewelry allergic reactions. 3. Three of 8 subjects with positive skin reaction. gave reactions to the metal plates.

  • Eosinophilic lung diseases are heterogeneous disorders characterized by varying degrees of pulmonary parenchyma or blood eosinophilia. Causes of eosinophilic lung diseases range from drug ingestion to parasitic or fungal infection as well as idiopathic. The exact pathogenesis of eosinophilic lung disease remains unknown. Urushiol chicken can frequently cause allergic reactions. Contact dermatitis (both local and systemic) represents the most-common side effect of urushiol chicken ingestion. However, there has been no previous report of lung involvement following urushiol chicken ingestion until now. A 66-year-old male was admitted to our hospital with exertional dyspnea. Serial chest X-ray revealed multiple migrating infiltrations in both lung fields, with eosinophilic infiltration revealed by lung biopsy. The patient had ingested urushiol chicken on two occasions within the 2 weeks immediately prior to disease onset. His symptoms and migrating lung lesions were resolved following administration of oral corticosteroids.

  • Paranasal sinusitis, especially chronic is one of the most common diseases in the field of otolaryngology. It is similar to Bee Yeun(鼻淵) in oriental medicine. Most cases of sinusitis are due to anatomical abnormalities within ostiomeatal unit or disturbed mucocilliary flow. The ostiomeatal unit is the first place of contact with bacteria and allergens during aspiration, and it can be obstructed easily by minute mucosal swelling due to anatomical narrowness. Therefore the treatment of paranasal sinusitis is not easy and often leads to recurrences in spite of long term treatment or surgical therapy. We studied 83 patients who had visited our hospital with complaints of nasal symptoms; they had been diagnosed as having paranasal sinusitis through an endoscopy or CT scan in another hospital and were diagnosed as the paranasal sinusitis through a PNS series. The results were as follows: 1. Age and sex distribution: The most common occurence was found between 6-10 and 1-5 years old. The Males Were 52($62.7\%$) and Females were 31($37.3\%$). 2. By residence 58 cases lived in apts: 25 lived in houses. 3. The longest duration of disease varied from a lower of 13 to a higher of 36 months in 22 cases and from 7 to 12 months in 21 cases. 4. The most common complication & past history with otolaryngologic or allergic disease were adenoid or tonsil hypertrophy & tonsillectomy and adenoidectomy (21 cases). In decreasing order the others were atopic dematitis, otitis media with effusion and allergic rhinitis. 5. Distribution of paranasal sinus disease was most common in both maxillary sinuses in 52 cases. 12 cases showed a normal PNS X-ray series but these had been diagnosed as paranasal sinusitis with an endoscopy or CT scan in another hospital. 6. Common sinusitis - related symptoms were from highest incidence to lowest nasal obstruction, postnasal drip rhinorrhea, frontal headache, cough with sputum. 7. The most administered of prescription was Gamibangpoongtongsungsan and Sunbangpaedoksan extract. 8. In 26 cases the subjects showed significant improvement symptoms in PNS X-ray series : In 21 case showed partial improvement symptoms.
