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.

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.

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.

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.

Non-lymphatic sporotrichosis is more difficult in diagnosis, lower in incidence and more variable in clinical picture than the classical lymphatic one. A case of non-lymphatic type affecting a female baby aged 2 months is presented, The patient has been suffering from the shallow ulcerated, crusted impetiginous lesian on the cheek area just below the right eye. The lesion has developed progreasively since about 1 month after birth. Clinically, its diagnosis was not easy, but was confirmed by culture on Sabouraud's media. It is thought that the age of initial onset in this case we experienced, is the lowest in recorded Korean literature.

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.

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%.

The morphologic differences hetween a mucoid and pasty type of Cryptococcus neoformans derived from pigeon drops were investigated using an eIectron microscope. The following results were obtained: No essential differences in ultramicroscopic structures were noted hetween the mucoid and pasty type of C. neoformans, but the capsule is thicker in the mucoid type than the pasty one and the intracytoplasmic structures were seen more clearly in the mucoid type. These differences seem to he related to chemical components and the difficulty of penetration of fixing solution through thick capsules. There were no differences between C. neoformans derived from pigeon drops and those from pathogenic strains which were reported by others. Therefore, C. neoformans derived form pigeon drops can infect humans.

The purpose of this paper is to describe a new apparatus which utilizes the principle of Van Tieghems hanging drop culture method. After using various methods of culturing fungi authors have found van Tieghems method to yield the most satifsymg result. Until now, this method has been slightly more tedious due to durability, storage, and quantity of culture necessary for each species. The new apparatus consists of 20mm plexiglass tubing cut in 16mm lengths and attache to a 16cm x12cm x2mm plexiglass plate with paraffin or manicure. These tubes a.re ranged in rows approximately 6cm apart with at least 8mm between tubes. Plates of varying sizes can be made to accornodate specific experimente. The authors developed thse inexpensive unbreakable plexiglass plates to allow for aimultaneous growth of various fungi and therefore more accurate comparison. Since these plates can be stored and handled easily, most af the disadvantages of using van Tieghems hanging drop culture rnethod have been eliminated.
