OBJECTIVES: To determine the level of mRNA expression of various members of the matrix metalloproteinase and tissue inhibitors in uterine leiomyoma compared with unaffected myometrium. Materials & Method: 30 cases of portions of leiomyoma and myometrium were collected immediately followimg hysterectomy. Thirteen cases were from proliferative phase and seventeen were from secretory phase of menstrual cycle. The mean age was 43.7years old. The level of expression of mRNAs of interstitial collagenase, gelatinase, stromelysin, TIMP-1,-2,-3 was determined by reverse transcriptase-polymerase chain reaction(RT-PCR) and normalized to GAPDH(glyceraldehyde-3-phosphate dehydrogenase) mRNA. RESULTS: Myometrium and leiomyoma expressed all the members of above mentioned matrix metalloproteinase family and tissue inhibitors. Leiomyoma expressed a significantly higher level of stromelysin-3 during secretory phase, an extremely lower level of 92kDa gelatinase and a significantly lower level of TIMP-3. The immunohistochemical localization of TIMP-3 was smooth muscle cell and arteriole wall of myometrium and leiomyoma. CONCLUSIONS: The increased expression of stromelysin-3 in uterine leiomyoma compared with myometrium suggests that this MMP may be involved in the formation of a more fibrous extracellular matrix in leiomyoma. The extremely lower expression of 92kDa gelatinase of leiomyoma means that leiomyoma do not invade myometrium and forms a separated mass. Decreased expression of TIMP-3 of leiomyoma suggests that TIMP-3 is required for differentiation and homeostasis of extracellular matrix of normal myometrium and function as a suppressive role of tumor development

BACKGROUND: Treatments inhibiting Propionibacterum acnes as like antibiotics for acne vulgaris can produce complications, and have their limited uses.OBJECTIVE: Antibodies reacting to P. acnes were produced from immunized chicken eggs, and were characterized by aggulutination test and inhibiting abilities to growth of P. acnes. METHODS: P. acnes were cultured, and their lipase were used as immunogen. Antibodies were purified from immunized chicken eggs by diafiltration. Their titers were measured by ELISA. Antigen-antibodies agglutination test was performed, and the ability of inhibitions of P. acnes grown in media was observed. RESULTS: Antibodies were well produced especially when 0.25 to 2 mg of immunogen were injected per one chicken. When antibodies were reacting to P. acnes, pellet formations were not shown because of agglutination above 17.8 pg concentration of antibodies, and acitivities of P. acnes were markedly suppressed on microscopic examination. Growth of P. acnes on media were also inhibited for quite a long time. CONCLUSION: Antibodies reacting to P. acnes were produced, and their abilities to inhibit the growth of P. acnes were confirmed. In future, produced antibodies from immunized chicken eggs would be hoped to be a main component of medication or cosmetics for improving or preventing acne lesions.

Prurigo pigmentosa is a chronic pruritic inflammatory dermaoss characterized by erythematous papules in a reticulated pattern that resolve leaving a reticulated, mottled hyperpigmentation. Most cases have been reported from Japan. Two cases of prurigo pigmentosa have been reported in Korean women. We experienced a casc of prurigo pigmentosa in a Korean man of 20 years of age. Histopathological findings of reddish papule showed exocytosis, sponsiosis, intraepidermal vesicles, hydropic degeneration of basal cells in the epidermis, and hyphohistiocytic infiltration in the upper dermis. Direct irnmunofluorescence was negetive. Therapy with dapsone, 50 mg given daily, resulted in a rerinable regression of the reddish papules. The daily dose of clapsone was reduced to 25mg; however, no new reddish, pruritic papules have appeared.

Epithelioid hemangioendothelioma(EH) is a low-grade tumor of vascular endothelial cell origin, which most commonly occur in the lower extremities of middle-aged patients with an equal gender distribution. It may occur on internal organs such as the liver or lung or bones. A 54-year-old woman who had a history of metastatic adenocarcinoma of unknown origin on the right inguinal lymph node, was presented to us because of a 1.0 x 1.0cm-sized and 2 x 2cm-sized two subcutaneous nodule on her right shin. On H & E stain, there were nests of round nucleated, polygonal, vacuolated cells, some of which contained fragmented erythrocytes. Factor VIII related antigen, CD31 was positive. A diagnosis of epithelioid hemangioendothelioma was established based on histologic, immunohistochemical studies. Wide excision was performed. There was no recurrence nor the development of new lesions so far.

59 children seen from Jan. 1990 to Jun. 1994 with epilepsy were retrospectively reviewed to evaluate the tendency of recurrence and the risk factors after the antiepileptic drug discontinuation. The population consisted of 59 children who were seizure free for more than 2 years and followed up for more than 1 year after the discontinuation via department of pediatrics, Yonsei University, Wonju College of Medicine. We analyzed risk factors of recurrence(age of seizure onset, seizure frequency before treatment, interval from seizure onset to start of treatment, duration from neurologic disorders, and EEG done just before discontinuation) between non-recurrent group(43 patients) and recurrent group(16 patients). The results were as follows: 1) In 59 patients with epilepsy, 16(27.1%) patients showed recurrence after the discontinuation and 14(87.5%) patients of those were developed during taperring and within less than 1 year. The probability of recurrent seizure by Kaplan-Meier curve at 12 and 24 months after discontinuation are 23.7% and 33.6% respectively. 2) There were significant differences on seizure frequency before treatement, duration from start of treatment to control (9.5months vs 31.1months), and associated neurologic disorders(11.6% vs. 56.2%) between non-recurrent and recurrent group. 3) There were no significant differences on age at seizure onset(70.6 months vs. 58.5months), interval from seizure onset to start of treatment(9.5months vs. 6.6months), length of seizure free(49.7months vs 39.3months), abnormal EEG finding done just before withdrawal(23.2% vs. 25.0% ) between non-recurrent and recurrent group.
