2.The Simplifed Hair Baiting Technique and its Practical Application.
Korean Journal of Dermatology 1982;20(5):695-702
In order to avoid contamination attributed to Vanbreuseghem hair haiting technique in the laboratory, the author contrived the following modified method. After adding 100ml of antibiotics solution (mixture of 500mg of Cyclohexamide, 20, 000u of Penicillin and 40mg of Streptomycin in 1,000ml of distilled water) in PVC phial containing 100gm of soil, it was gently agitated for an hour and lefted to be settled for 12 hours. The suspended solution obtained and a batch of horse hair were randomly distributed on a Petri dishfitted with blue cloths, then cultured at 24C'. The overall results obtained from this modified method were not as satisfying as that of the Vanbreuseghem method but a few advantages such as simplicity of the procedure and significantly lower laboratory contamination implicated its practicality. Furthermore, this method was also found to be useful in the first isolation of infected animal hairs, hair perforation tests and as a substitution for artificial media. For the cross mating, a patch of blue cloths was laid on top cf moist sterilized soil evenly spreaded on a Petri dish. Then hair-baiting procedure was performed and good results were obtained.

3.Mating Type and its Mycological Characteristics of Micrpsporum Gypseum Comples.
Korean Journal of Dermatology 1981;19(6):835-846
Granuloma pyogenicum is a benign vascular tumor, usually about 0.5 to 2cm in diameter. It occurs as a single lesion with few exceptions and consists of pedunulated nodule with a dull red or slightly purplish color. We observed a 29-year old man who had multiple satellite recurrences in the scapular region which developed after excision of a single lesion of granuloma pyogenicum. Histapathologic findings showed many newly formed capillaries that had prominant endothelial cells and showed varying degrees of dilation without appearance of epiderrnal collarette sign. The lesions were much improved by X-ray irradiation.

4.Evaluation of Factors for Accurate Diagnosis of Scabies.
Korean Journal of Dermatology 1974;12(1):13-20
In order to evaluate the accurate diagnosis of scabies through exatr.inations of all requred. conditions, the author conducted an observation on 769 cases of scabies at the Department of Dermatology, Kyungpook University Hospital from January, 1962 to Octover, 1973, In 1962 the frequency of the disease appeared to be low but it dramatically rose to 20 or 30 times between 1963 and 1966, again showing an increasing tendency from 1971. The ratio of frequency between male and female was 4.2: 1. Seasonal occurrence of scahics was found to be highest in winter. Infectious rate in the family was 83.3% and incubation period vas estimated from 15 days to 2 months. Acarus scabiei or its ova were found in 46.5% of all cases examined and in patients over 16 years of age. Acarus scabiei or ova were chiefly found in vesicles of the finger web but the ova were also found in the subungual fold of the finger, which is an important site of examination.

5.Clinical Observation on Pyodermas.
Korean Journal of Dermatology 1974;12(1):1-8
Clinical observations were made on 251 cases of pyodermas at the Department of Dermatology, Kyungpook University Hospital from 1968 to 1972. Especially noteworthy is the application of josamycin to 41 cases of pyodermas to observe its therapeutic effects. Since 1968, the frequency of pyodermas has shown an annual increase. The ratio between male and female was 1. 4: 1, gradually changing from 2. 3: 1 in 1968 to an almost balanced incidence in 1972. The age of onset. differed with types of disease, but 76. 2% of all cases occurred before the age of 15. The outbreaks of impetigo bullosa and impetigo vulgaris were found to be affected by season, the highest prevalence being in summer. Seasonal occurrence of all cases was found to be 45.5% in summer and 24. 3% in fall with no noticeable change ohserved in spring and winter. Predilection sites of the disease differed according to the type of the disease but all types showed a marked predilection for the exposed areas as against the covered areas (4 times). Sensitivity of causative organisms to antibiotics was found to be fairly high to cloxacillin, novobiocin and ampicillin, and relative to kanamycin, streptomycin and doxycycline but all tested cases showed resistance to tetracycline, chlortetracycline and oxytetracycline. Josamycin was effective in all types of pyodermas, and was dramtical]y so in impetigo bullosa of which pustules disappeared within 3 or 5 days of treatment. Two out of 41 cases complained of abdominal pain and weakness. The sensitivity of the causative organisms of all types of pyodermas to josamycin was 83. 3%.

6.Susceptibility of Dermatophytes to Antifungal Drugs.
Korean Journal of Dermatology 1979;17(3):221-227
With isolated strams of dermatophytes, susceptibility tests were undertaken to antifungal drugs, and the results of both tests by inoculation of fungal suspensions and, fungal mats were compared, also the combined actior.s of drugs against isolated strains were evaluated, Diverse susceptibiIity patterns were observed among different fungal species, however, no arminor susceptibility differences were detected among strains of same species. Among drugs tested, tolnaftate showed the most strong antifungal ar.tion, and Ep, floccoaum was the most and T. mentagrophytes was the least sensitive species to drugs. MIC levels by mats inoculation were generally far higher than that of fungal suspension, particularly with tolnaftate it was several hundred folds higher by fungal mats inoculatian. Combined actions of drugs were generelly elevated against test strains, when miconazole cornbined with tolnaftate, the action was synergistic against T. mentagrophytes, and when tolnaftate combined with griseofulvin or siccarin cornbined with griseofulvin, thactions were elevated to T. rubrum.

7.Perfect State of Trichophyton mentagrophytes and Their Related Infections.
Korean Journal of Dermatology 1984;22(6):610-618
A mating study was performed by crossing 333 isolates of Trichophyton mentugrophytes with+and tester strains of Arthroderma vanbreuseghemii, A. benhamiae and A. simit from January 1980 to December 1983 Three hundred and thiirteen were compatible with A. vanbreuseghemri consisting of 167 of+type and 146 of type and twenty were indeterminate. The cleistothecia formed by crossing the isolates with tester strains of A. vanbreaseghemii were fewer in number and smaller in size than those of tester strains. The sexual dogeneration was observed in all of the isolates compared with tester strains. The colonial morphological features of the isolates of T. mentagrophytes were observed as 24p isolates of the granulosum-asteroides form, 66 of the powdery form and 7 of the downy form on 1/10 Sabouraud agar with salts in culture. The mat- ing type showed the higher type in the granulosumasteroides forrn and + type in the powdery and downy forms. The + type increased from 1981 to 1983, and the type showed a marked increase in 1983. The + type was predominant in tinea pedis et unguim and tinea cruris, and type in tinea faciale and tinea manuurn. The + type showed nearly equal incidence in the spring, winter and summer, and the lowest in the autumn, compared to the highest in the winter and the lowest in the summer in the type.

Korean Journal of Dermatology 1988;26(1):73-81
These clinical and mycological observations were made on 898 cases of tinea facisle diagnosed by the clinical findings and KOH exsmination among the 137,197 out-patients exsmined for five years from Jaunary 1981 to December 1985 at Chilgok Catholic Skin Clinic, Taegu, Korea. Following results were obtained: 1. The annual number of patients with tinea faciale was 159(0.75% of the total outpatients) in 1981, 174(0.56%) in 1982, 181(0.67%) in 1983, 181(0.67%) in 1984,and 203 (0.83%) in 1985. 2. Of the 898 patients, male patients numbered 395 and female 503. Although the age distribution of patients was highest under age 14 in both sexes, males outnumbered females slightly before age 19 and, as age advanced, female predominance became more marked. 3. Of the 898 patients, 7Z6 organisms composed of 5 species were isolated. The species isolated were in the order of decreasing frequency, Trichophyton(T.) mentagrophytea (296,40.8%), Microsporum(M.) canis (218,30.0%), T. rubrum (189,26.0%), M. gypseam (21,2.9%), and Epidermophyton floccosum (2,0.3%). 4. M. canis was the chief cause of tinea faciale in children under 14. The infection due to T. mentagrophytes and M. canis outnumbered T, rubrum markedly in the young age group before 14, but T. rubrum predominated in the middle age group from 20 to 29. In the old age group after 40, T. mentagrophytes reappeared as a major cause of the disease. 5. T. mentagrophytes predominated in rural area and M. cania in urban area but no sexual variation was found. T. rubrum and M. gypseum prevailed slightly more in urban areas than in rural areas. 6. Eczematous annular ringworm (without central clearing) types were seen most frequently in the cases cssed by T. menagrophytes and clsssic ringworm types were seen most frequently in the cases caused by M. cania 7. Coexistent fungal infections were chiefly T. corporis in the csses of T. mentagrophytes and M. canis, but T. pedis and T. unguium in the cases of T. rubrum. 8. As a result of mating studies, 177 strsins of T. mentagrophytes proved to be Arthroderma vanbreuseghemii (51 of the "+" mating type and 126 of the "-"mating type), 12 strains of M. gypseum proved to be Nannizzia(N) incurvata (4, "-" and 8,"-") and 4 proved to be N. gypsea (2, "+" and 2, "-" ).

9.The Punch Method to Detect The Causative Organisms of Onychomycosis.
Korean Journal of Dermatology 1978;16(6):429-433
Onychomycosis can be diagnosed by mycological examination, but it is not easy to detect its causative organisms because the positive rate of culture is lower and its scores are variable due to the contamination inherently introduced in the current method used in sampling the ovychomycosis organisms. It was suggested that the scores depended upon the handicraft of operates and the gainning method of nail material, so we modeled the watch mending drivers into the punching instruments, and holed deeply & widly through the nail plate, from the surface to the bottom. Afterward, the KOH mount & culture were performed to compare this new punch method used with that of standard scrapping method. Through the KOH examination more numerous hypaes were found in the punch methods sample than the scrapping methods sample. Also, the punch methods positive culture rate was found to be 2. 5 times higher than that of the scrapping methods culture rate, with a 5 to 5. 5 times lower amount of contamination. In conclusion, the punch method was found to be a more precise and effective method of obtaining onychomycosis organisms. Although this method required a slight greater time to perform than the standard scrapping method, I believe it will be a valuable aid in the detection of causative organisms of onychamycosis.

10.A Case of Familial Telangiectasia of Face.
Korean Journal of Dermatology 1977;15(4):459-463
A case of familial telangiectasia of face resembling lupus erythematosus but no having other involved symptoms, except ichthyosis vulgaris of lower legs in all 4 sisters, appeared on 8 months through 2 years after birth is reported Authors suggest this case to be simplified congenital telangiectasia of face, because of not consisted with preexistiong various diseases such as Bloom's syndrome, Ataxia-Telangiectasia, Rothmund-Thomsons' Syndrome, Dyskeratosis congenita, and Cockayne's syndrome, which show the familial telangiectasia of face.
