Demodicidosis is caused by the enormous infestation of 400 micron sized demodex folliculorum which normally exist, though in small number, in pilosebaceous unit. Its characteristic clinical feature is erythema and erythematous indurated papulopustular eruptions combined with itching and buming sensation. Microscopic examination of indurated pustule always reveals demodex folliculorum. Many authors have reported that demodicidosis aggravated by avoidance of using soap, long-term use of cosmetic cream, especially cold cream, topical or systemic use of corticosteroid. Our patiednts were housewives of 46,39, and 42 years old and presented characteristic clinical featurss and skin lesions by topical application of corsicosteroid for 1~2 years and were diagnosed as steroid acne. But simple microscopic examination reveled demodex folliculorum. We treated them with 5% sulfur lintment and soap and water cleansing of face with remarkable clinical improvement.

Epidermolysis bullosa Dystrophica is rare, chronic non-mflammatory mechanobullous disease of hereditary trait, which easily produces bulIa by minor trauma or spontaneousIy. The lesions usually appears from birth or in infant involving especially lower leg, hand, foot and lea,ds to erosive, hemorrhagic bulla, secondary infection, pruritus and scar formation and sometimes deformity of nails and cicatrical alopecia. It sometimes involves oral mucosa, esophagus, eye, tooth, bone, respiratory system, anus and vagina. This disease has rare tendency for carcinogenesis from cicatrical Iesions. These manifestations are more severe in recessive type than in dominant type. We had observed 5 cases of EBD at Ewha Womans University Hospital from Sept. 1975. to Jul. 1976. Among 5 cases, 4 cases occurred from birth, 1 case occurred at age l. Skin lesivns were hand, foot, knee area in all 5 cases. Head, face were involved in 2 cases. Arm, leg, trunk, buttock were involved in 3 cases. In skin manifestations, bulla, erosive bulla, secondary infection, scar formation, pruritus, nail deformity, positive Nikolsky sign were observed in all 5 cases. Hemorrhagic bulla, miliaria. were presented, in 1 case, alopecia in 2 cases. Aggrevated season were summer in 4 cases, spring in 1 case, HistologicalIy, microscopic observation, after H@-E stain, revealed hyperkeratosis in 3 cases, acanthosis in 2 cases, partial atrophy in 1 case, partial ulcer in 1 case, snbepidermal bulla in 5 cases, chronic nonspecific inflamma- tory cell infiltration of upper dermis in 3 cases, fibrosis of lower dermis in 1 case.

Darier's diseaae is relatively rare dyskeratotic and inheritable dermatoses of an. autosomal irregular dominant gene. The authors observed one case of typical Dariers disease with the family hietory of three generatian of autoaomal daminant trait. 22 year-oid patient we observed has had the generalized pruritus and dark dirty and warty patehes distribnted almost on the whole skin surface especially on trunk, back and face for about 10 years. Histopathologically, the lesion showed lacunae, corps ronds and grains which are compatible with typical Dariers disease.

Verrucous hemangioma is congenital hemangioma, which is structural varients of capillary or cavernous hemangioma. And it is vascular malformation, in which reactive epidermal acanthosis, papillomatosis, hyperkeratosis develope secondarily. Though foreign anthors have reported some cases of this disease, it is rare hemangioma and it never has been reported in Korea. This 13 year-old, healthy female patient has erythematous patchs on her left knee at birth. It grew become coin to egg sized. Because of verrcous iuflammatory reaction of irregular verrucous surfaced plague, the lesion become necrotic thick crusty plague with severe offensive odor and patient complained of severe pain & motion limitation on her left knee. Urinalysis, C B C, chest PA were within normal limit. PPD test was negative. Lt. knee AP & lat. revealed. Marked destroyed soft tissue on anterior portion of Lt. knee and no bony pathological changes were demonstrable. Histopathologica.11y, hyperkeratosis, parakeratosis, acanthosis, papillomatosis in the epidermis and numerous capillary lumina, capillary dilatation, proliferation of endothelial cells and mild infiltration of inflammatory cells in the Dermis. And fibrosis in the Dermis & Subcutaneous tissue are seen.

Juvenile Xan anuloma is granulomatous, benign disseminated Xanthomatous disease, which i r cytosis of unknown origin, due to lipid, metabolism disturbance. Spontaneous remi. is possible authors have reported some cases of JXG involving only skin or combii extracutaneous lesions, In our country, cases involving onIy skin have bcen reported. This I-year-old norered healthy male baby has yellowish brown coloxed pinhead to rice sizeci gers of well defined. round, dome shaped smooth surface in face, trunk, lower abdomen without any subjective symptomes. Serum lipid level i iid chest p-A,urinalysis, CBC, L.F.T. are normal. Family history showed ific finding and physical examina.tion shows nothing remarkable except for skeen lesions.

It has been reported that kanamycin, a useful agent in the treatment of gram-negative and other infectious disease, has a negative inotropic action in isolated cardiac muscle preparation and also it decreases the amplitude of high K+ -induced action potential of guinea pig atrium. These findings imply that kanamycin has a property of Ca2+ antagonist. In this study, the effects of kanamycin on cardiac Ca2+ current were investigated in isolated rabbit ventricular cells by using a whole cell clamp nethod.The results are summarized as follows ; 1) Kanamycin caused a depression fo cardiac Ca2+ current in a dose dependent manner and its effect was observed in a whole memberane potential renge. 2) The decreasing effect of kanamycin on Ca2+ current was inhibited by high Ca(2+)-Tyrode solution and such inhibition was also observed in high Sr2+-Tyrode solution, but in the case of Cd2+, well known inorganic Ca2+ antagonist, the current through Ca2+ channel was greatly decreased when the perfuaste was changed from high Ca(2+)-Tyrode to high Sr(2+)-Tyrode solution. 3) In the presense of kanamycin, the decreasing pattern of Ca2+current by repetitve depolarization was not specific as in the case of verapamil. 4) Neomycin decreased Ca2+ current similar to kanamycin.From the above result, it may be concluded that kanamycin has competitive antagonistin effect on cardiac Ca2+ current.

PURPOSE: Bile acids (especially deoxycholate) was known to be toxic and mutagenic on colon epithelium. They proposed at least four mechanisms for the bile acid toxicity. It is the one of these mechanisms that bile acid inhibits the xenobiotic metabolizing enzyme activity (esp glutathione S-transferase, GST). So we measured the cytosolic GST level of colon carcinoma cell lines after deoxycholate exposure whether or not the deoxycholate lowered the cytosolic GST activity. METHODS: Three colon cancer cell lines (LoVo, SW480, HT29) were used for this study. We calculated the cellular toxicity by MTS method. And cytosolic GST activity was measured according to the method as Habig described. For total GST activity, 2.5 mM 1-chloro-2,4-dinitrobenzene was used for substrate, and measured as absorbance in 340 nm. RESULTS: Basal cytosolic GST level for LoVo, SW480, HT29 cell line was 514.59+/-27.01, 291.63+/-38.44 and 344.58+/-47.92 nmol/min/mg cytosol protein. GST level did not changed significantly after 5 days culture without DCA. But GST level was decreased significantly to 128.63+/-21.35, 134.33+/-41.76 and 163.10+/-22.73 nmol/min/mg cytosol protein each cell line after 5 days deoxycholate exposure (p<0.005). CONCLUSION: Cytosolic GST level was lowered significantly after deoxycholate exposure for 5 days. One of the mechanisms of bile acid toxicity for colon cancer cell is proposed to inhibit cytosolic GST activity.

Tatbion is a tripeptide, reduced form of Glutathione(GSH or p-glutamyl-cysteiny1 -glycine). Glutathione(SH compound)is believed to inhibit melanin formation by combining witb the copper in tyrnsinase whicb is essential in the conversion of tyrosine to DOPA (3, 4-dihydroxyphenylalanine) and DOPA to DOPA-quinone or by forming cornplex with the intermediate in the tyrosine-to-melaa.in reaction. The effect of Tathion in the treatment of melasma has not been reported in Korea. We have observed the effect of Tatbion in 150 patients with melasma. After the average duration of Gwks of treatment(50-100mg tree tirnes/daily), we were abIe to grade the results as follow. Excellent(Pigmentation almost disappeared): 17. 4 % Good (Pigmentation markedly improved): 56. 7% Fair (Pigmentation slightly improved: 7. 3% None (No effect) : 18.6% The result showed relatively good effects of Tathion in the treatment of 122pts (81.4%) with melasma in total. The brief review of literature on the treatment of melasma was undertaken.
