BACKGROUND: Apoptosis is a highly selective form of cell suicide with characteristic morphologieal and biochemical features, including chromatin condensation, formation of apoptotic bodies, and DNA fragmentation by the activation of endonucleases. Various cytokines and physical or chemical factors can provoke apoptotic changes in the skin. OBJECTIVE: We investigated the cytotoxic effects with epidermal cytokines and their combinations, K+ ionophores, protein synthesis inhibitor(emetine), inhibitor of endogenous endonuclease(aurintricarboxylic acid, ATA), sodium azide, and retinoic acid witp human epithelial tumor cell lines(A431 cells) to examine the degree of induction of apoptosis in the epidermal keratinocytes. METHODS: Induction of apoptosis was measured in cultured human keratinocytes, keratinocyte cell lines(A-431, HaCat, KB cells), cultured human melanocytes and malignant melanoma cell lines(SK-28, SK-30) using a mixture of ethidium bromide and acridine orange, DNA agarose gel electrophoresis and TUNEL staining. RESULTS: l. In the A-431 cells, (1 to a certain degree, the combination of IFN-gamma and TNF-alpha could only induce apoptosis. Q2 most of K+ ionophores were observed to induce necrosis rather than apoptosis. Q3 emetine, a protein synthesis blocker, was found to induce apoptosis in a dose-dependent pattern. Q4 sodium azide at a concentration of 1% .induced apoptosis rather than necrosis. Q5 retinoic acid inhibit the beuvericin induced apoptosis. 2. In human keratinocytes, Ql more resistant in the induction of apoptosis than any cultured keratinocyte cell lines p aurintricarboxylic acid(ATA)-an endonuclease inhibitor, could inhibit UV induced apoptosis 3. In human keratinocytes and cultured keratinocyte cell lines, c-PAF inhibit the beauvericin induced apoptosis. 4. Human melanocytes is very resistant for the induction of apoptosis by beauvericin. 5. In the melanocytes and melanoma cell lines, sodium azide and beauvericin induced necrosis rather than apoptosis. CONCLUSIONS: The epidermis is continuously exposed to toxic factors which might induce cell death. With the above results, the induction of appeared to be rather resistant, epidermal cell apoptosis which may reflect the existence of some endogenous protective mechanisms in the epidermis to survive at certain toxic environments; melanocytes showed high expression of bcl-2 protein which could play a role in endogenous defense against toxic environments of the epidermis.

Forty-three patients with papulo-pustular rosacea with Demodex(D.) folliculorum were treated for 8 weeks on a random basis either with tetracycline 250 mg three times daily or with metronidazole 250 mg three times daily. Both drugs produced an improvement which was greater after 8 weeks than after 4 weeks, but there was no significant difference between them. The number of D. follilculorum after treatment with tetracycline was slightly decreased, but the number of D. folliculorum after treatment with metronidazole was more decreased than the tetracycline group. Metronidazole appears to be a effective drug for the treatment of rosacea with D. folliculorum.

The important prerequisite for treatrnent of onychomycosis is the removal of as rnuch fungus-infected nail material as possible. Nincty-five patients with anychomycosis were treated with using urea preparations under occlusive dressings. The urea preparations were quite successful in maceraing the nail plate from the nail bed, allowing the easy removaI of diseased nails in all cases except one. The urea preparations removed only abnormal nail. Completely normal nail was unaffected. After nail avulsion, 95 patients were treated for 6 months with combination clotrimazole and ketoconazcile(group A), or with clotrimazole only(group B). Of the 38 patients in group A who complcted the treatment, 25(65.8%) were cured 6 months later by clinical and mycological criteria, compared to 20(47.6%) of 42 patieries in group B.

Lichen planus is rare in Korea and localized lichen planus on the lip without other skin lesions is even rarer. A 77-year-old man has oozing and crusting patches und somewhat ulceration surrounded by whitish reticular elements on violaceous base on both lips with burning sensation and pain. A 63-year-old man has well demarcated violaceous white reticular patches on the lower lip, buccal mucosa, glans penis and coronal sulcus. Clinical and histopathological studies of two cases showed typical features of lichen planus. They were treated with systemic and topical corticosteroids and showed much improvement.

The Enchondroma is a benign cartilage forming harmartoma arising chiefly from short tubular bones on hands and feet. If on a long tubular bone or flat bone such as femur or ilium, it is most likely to be a true neoplasm such as chondrosarcoma, not a harmartoma. A case of enchondroma was reported. It occurred over right ischium of 19 years old male and was found incidentally by roentgenogram. The lesion was biopsied and diagnos's was confirmed by histologic examination. It was treated by curretage with filling of cavity with bone chips. Post operative-course was uneventful.

To Evaluate the clinical characteristics of childhood-onset systemic lupus erythemoatosus (SLE) and analyse the factors related to outcome of renal function in lupus nephritis, we reviewed medical records of 18 cases of SLF diagnosed at the Department of Pediatrics. Pusan National University Hospital from January 1981 to December 1990. The results were as follow: 1)Male to female ratio was 1:2.6. 2) Nephropathy was the most common initial impression, and 8 cases were diagnosed as SLE at first. 3) The clinical menifestation. was ANA (+), malar rash, renal disorder, hematologic disorder in frequency. 4) Diffuse proliferative lupus nephritis was the most common in renal histopathologic studies. 5) Among the follow-up cases, active lupus was 39%, remission was 28%. 6) As factors related to outcome of lupus nephrits were, hypertension and proteinuria were siginificant statistically.

A 79-year-old man with balanitis circumscripta plasmacellularis(BCP), presenting as an erythematous constricting band of the inner surface of the prepuce encircling the penile shaft is described. The biopsy specimen of the lesion showed, in addition to the typical histologic findings of BCP, increased fibrosis and decreased amount of elastic fibers which correlate well with our clinical observations. Electron microscopic examination revelaed no viral particles or elastic fibers. Immunohistologically, IgG was found to be the major immunoglobulin class in the plasma cellular inf iltrate.

Hepatic changes in eight cases of systemic lupus erythematosus(SLE), were studied to evaluate the nature of hepatic injury of SLE and its relation to lupoid hepatitis. Common histologic changes of the liver in SLE included intralobular necro-inflammatory activities, fatty change, canalicular bile stasis and mild perivenular and Disse space fibrosis. The fatty change and intralobular fibrosis were thought not to be due to SLE itself but associated with steroid administration or chronic alcoholic consumption. The necro-inflammatory changes were usually mild and features of chronic active hepatitis with periportal destruction occured in one case. Symptoms related to the involvement of many other organs than the liver appeared much frequently in patients with SLE than lupoid hepatitis, suggesting that the SLE involving liver and the lupoid hepatitis are different diseases.
