1.An Improved Baiting Method for Isolation of Keratinophilic Fungi.
Korean Journal of Dermatology 1968;6(1):29-34
In order to isolate the keratinophilic fungi from the soil, 7x10cm vinyl envelope were used in shich 10 rhomboid shaped holes (1x1cm) were made, so that when the human scalp hairs as baiting material were laid out straight in the envelope the keratinophilic fungi would be baited to the open part of the hairs in envilope in the 6 different places for 20 days in Kyungpood National University Hospital campus from April 1967 to September 1967. The author's newly improved baiting method with the hairs in the vinyl envelope was simple and the results were more satisfactory for isolating keratinophilic fungi compared with the original Vanvreuseghem's hair baiting method.

3.A Study of Cutaneous Manifestations by Clofazimine in Leprosy Patients.
Korean Journal of Dermatology 1983;21(5):537-547
Clofazimine (Lamprene or B668) is a phenazine congener that is used in leprosy, and the patients treated with the drug may develop red discoloration, dark brown pigmentation and ichthyotic skin. The authors observed 181 leprosy patients who had developecl discoloration, pigmentation and ichthyotic skin during clofazimine therapy, as well as disappearance of the pigmentation after stop of it. The results are summarized as follows: 1) Reddish discoloration was most frequently observed 2 weeks after beginning treatment in 66 patients (50. 4%), which showed earlier in the higher dosage grow up, 2) Dark brown pigmentation was iviost frequently observed 4 weeks after beginning treatment in 64 patients (48. 9%), which showed earlier in the higher dosage group. R) For histopathological evaluation of pigmentation, various ataining rnethods were used. On unstained frozen sections, yellow brown crystals were scattered in the dermis of both discolored and pigmented skin, and in H R E stain pigments, melanin were niarkedly increased in the epidermal basal layer and a, faint yellow brown. ghost was seen in dermis of pigmented skin. With fat stains using oil-red-0 and Sudan III, reddish amorphous materials were scattered in and around the cytoplasm of the macrophages c>f the pigmented skin. 4) Ichthyotic skin was observed in 97 patients, and most frequently 2 and R months after beginning treatment in 26 patients (26. 8%), but it was never observec1 in 34 of all patients in spite of a continuous intake of the drug for more than a. year. -countinue-

Young Ho SANG ; Sang Lip CHUNG
Korean Journal of Dermatology 1990;28(6):708-714
Fibronectin(FN) is a major component of the extracellular matrix and is able to bind to cells and other components of the matrix. Although the cell producing the largest amounts of fibronectin is fibroblast, the pro duct,ion on FN also has been described in cultured keratinocyt,e and epithelial tumor cells of basal cell carcinoma(BCC). Recently, functional role nf FN in relation to biologic behavior of BCC and squamous cell carcinoma(SCC) is open to speculation. The authors investigated the localization of FN in the lesional skin of 5 cases of BCC, 4 of SCC, 5 of psoriasis and 5 normal skin using direct immunofluorescence technique with antifibronectin antibody to find out the production of FN in keratinocytes and tumor cells. 1. In the skin of BCC, FN was presented in a thick, linear depositions along the margin of tumor lobules in all cases, and as fillamentous deposits or scattered points in the nest of tumor cells in 3 cases. 2. In the skin of SCC, FN was presented in a thin, coarse depositions around the margin of tumor but not presented within the tumor nest in all cases. R. In psoriasis, FN was observed in horney layer and upper part of epidermis. It was presented more abundantly in dermo-epidermal junction, papillary and reticular dermis than in normal skin. 4. In normal skin, FN was absent in the epidermis but presented in dermo-epidermal junction and blood vessel wall of upper dermis, the amount of FN was decreased from papillary to lower dermis.

5.Relationship of Clinical and Laboratory Findings to Lupus Band Test in Patients with Systemic Lupus Erythematosus.
Korean Journal of Dermatology 1989;27(2):187-196
The lupus band test(LHT) has been proposed as a diagnostic test for lupus erythematosus(LE), differentiating discoid I E from systemic LE and also has prognostic values. For the better understanding of relation between LBT and prognosis in SLE. a study was carried out in 32 SLE patients with skin lesions. Immunofluorescent study was done with biopsies taken from involved skin and uninvolved skin of patients with SLE. The results were as follows . 1) Incidences of a positive LBT were 84% in both involved and uninvolved skin and IgM was most frequently deposited(66% & 72%) in both, whereas IgA was least frequently deposited(34% & 19%) in both. 2) Deposits in DEJ of IgG, IgM, IgA and C were found with approximately same frequency in patients with different clinical manifestations and different laboratory findings. 3) Incidences of positive LBT in patients with renal disease were approximately same as in patients without renal disease. And deposits of all clssses of immuno glcbulins were found with about the same frequency in these two groups. 4) A positive LBT composed of IgG alone or IgG and other Igs were associated with an increase of anemia, ANA, anti-DNA and hypocomplementemia. Ten renal biopsies showed diffuse proliferative glomerulonephritis(GN) in focal proliferative GN in 3 and membranous CiN in 2 and no correlation to immune deposits.

Korean Journal of Dermatology 1989;27(5):495-501
Fibronectin(FN) is a physiologic glycoprotein presenton cell surface and in connective tissue, extracellular matrix and plasma. Increased plasma FN levels have been reported in the patients with psoriasis, connective tissue disease, internal malignancy, squamous cell carcinoma and basal cell carcinoma. The author investigated the plasma FN levels in 30 patients (males 13, female 17) with psoriasis and 23 healthy subjects (male 13, female 10) by gelatin sepharose 4B affinity chromatography and Laurells rocket immunoelectrophoresis method. The results were as follows : Plasrna JN levels were 450.4+/-80.3pg/ml in the patients with psoriasis and 334.0-51.3pg/ml in healthy subjects. There was no relationship between age graups and sex. Plasrna FN levels in the patients with psoriasis were higher than those of healthy subjects(p<0.001). There was no relationship between the levels of plasma FN and clinical severity of psoriasis.

Korean Journal of Dermatology 1978;16(4):337-341
Darier's disease is a congenital dyskeratosis and is as an autosomal dominant reait but a case with a family history is relatively rare and only 2 such cases have been reported in Korea. We present typical Darier's disease occuring in a mother and her 2 daughters. A 45 year-old female has shown muitiple, confluent, dirty verrucous keratotic papules on the seborrheic area and whitish papules on the sotf palate since the age of 7 year-ole. Histologically there, are corps ronds, grains and suprabssal lacunae in the epidermis.

8.Direct Immunofluorescent Studies in the Scabies.
Korean Journal of Dermatology 1984;22(4):381-386
There are many reports about the deposition of immunoglobulins and complement by direct immunofluorescence(DIF) in the lesion of scabies. The authors investigated the immunoglobulins and C, for the purpose of studying the immunologic reactivity of the host to scabies mites by DIF. The results are summerized as follows: Total number of the cases investigated were 20 (18 males, 2 females), of whom 11 were in their third decade of age. The clinical forms of the tested lesions were papular type (7 cases), nodular type (12 cases), and Norwegian type (1 case). The durations of the patients were mostly within 2 months, but was 9 months in 1 case of nodular type, Deposition of immunoglobulin and C, was demonstrated by DIF in 10 of 12 cases (83. 3%) of nodular type, and 1 of 7 cases (14. 3%) of papular type. The Norwegian type showed negative results. There seemed to be no relation between the duration of scabies and positive rates. Of 20 cases tested, immunoglobulin and C, were deposited in the vascular wall in 11 lesions (55%), and at the dermoepidermal junction in 3 lesions (15%). While in 1 of 7 cases of papular type both IgM and C, were observed, IgM and C, were noted in 7 and 9, respectively, in 12 cases of nodular type.

9.A Study of the Incidence of Stratum Corneum Antibodies and Upper Epidermal Cytoplasmic Antibodies in Sera from Patient with Psoriasis and Normal Human.
Korean Journal of Dermatology 1988;26(5):653-665
The authors investigated the incidence of stratum corneum and upper epidermal cytoplasmic antibodies with 30 untreated and 20 treated psoriasis sera, and normal human sera using normal human skins of 5 different sites and psoriatic lesion by the method of indirect immunofluorescence in order to evaluate immunologic responses i n psoreasis. The results are summarized as follows . I) The positivity of stratum corneum antibodies in untreated psoriasis sera(78.7%) was si, nificantly higher than that in normal sera(64.0%). The incidence of stratum corneum antibodies in untreated psoriasis sera was found to be the highest in the arm, followed by the scalp, leg, abdomen, and face as substrate. 2) The positivity of stratum corneum antibodies in psoriasis and normal human sera was significantly higher when tested with the psoriatic lesion as substrate than norma! skin as substrate, 3) The titer of stratum corneum antibodies in 5 sera using human skin obtained from 5 different sites on the body as substrate are the highest in the arm, and leg, and(in decreasing order of frequency) the scalp, abdomen, and face. 4) The positivity of upper epidermal cytoplhsmic antibodies in normal human sera (40.7%) was significa.ntly higher than that in untreated psoriasis sera(21.3%). 5) Ir.. the majority of cases, upper epidermal cytoplasmic antibodies coexisted with straturn corneum antibodies in the sera of patients with psoriasis and in the sera of normal humans.

10.Observation about Dapsone-Resistant Cases of Leprosy Partients by Clinical and Bacteriological Aspects.
Korean Journal of Dermatology 1981;19(1):39-46
Fifteen hundred seventy-one leprosy patients registered in the leprosy Mission Hospital from Mar. 1957 to Sep. 1980 were investigated for dapsone resistance by clinical and bacteriological aspects. The results are as follows: There were 29 suspected dapsone-resistant cases out of a total 1571 registered leprosy patients (1. 85%), 26 of 650 of lepromatous type(4. 00%), and 3 of 164 of borderline type (l. 83%). In 1969, we observed the first case if suspected dapsone-resistant leprosy. Since then, suspected dapsone-resistant cases increased and we observed as many as 8 cases in 1977. But frequency of cases has decreased since 1978. (countinued..)
