1.Expression of type IV collagen and laminin genes by skin fibroblasts in culture.
Korean Journal of Dermatology 1992;30(3):317-324
Basement membrane zone gene expression by fibroblast cultures was examined by molecular hybridizations with human sequence specific cDNAs corresponding to type 1V procollagen and laminin subunit polypeptides. Northern transfer analysis with total RNA revealed the presence of specific mRNA transcripts for al (IV) and a2 (1V) chains of type 1V procollagen as well as Bl and B2 chains of laminin. Laminin A chain mRNAs were not detected using the same RNA preparations. The molecular size of al (1V) and a2 (1V) procollagen mRNA revealed 6.8kb and 6.7kb, respectively. The molecular size of Bl chain of laminin revealed 5.6kb, and B2 chain revealed 8.2 and 5.5kb polymorphic transcripts. In slotblot analysis using densitometer, steady-state levels of type IV procollagen and laminin mRNAs indicated that they were in relatively low abunclance, as compaired with type I procollagen mRNA. Quantitative levels of al (IV) and laminin Bl chaii mRNAs were more abundant than those of a2 (IV) and laminin B2 mRNAs. The mRNA ratio of al (IV)/a2 (lV) and laminin Bl/B2 were 1.9 and 1.5, respectively. These results demonstrate evidence for differential regulation of the expression of different basement membrane zone molecules during the formation of basement membrane.

BACKGROUND: Pityriasis versicolor(PV) is a superficial mycosis, theoretically unusual in children. Epidemiologic and clinical data for children with PV under 14 years were collected. OBJECTIVE: The purpose of this study was to evaluate the clinical features of PV in the young. METHOD: We included all cases of PV in patients under 14 years of age observed in our department from 1981 to 1995. All cases were diagnosed on the basis of clinical criteria and were confirmed by microscopic examination. RESULTS: From 1981 to 1995 we encountered 32 cases of PV in children, compared with 637 cases in adults; thus children represented 4.7% of all cases. The ratio of male to female was l. 7:1. Among the age groups, the incidence was the highest in the 10-14 years(43%). The monthly prevalence was the highest in August. Distribution of the lesions were the face(40.9%), neck (25%), chest(13.6%), back(11.3%), extremities(6.8%) and abdomen(2.2%). The incidence of hypopigmented lesions was 70.4% and that of hyperpigmented lesions was 29.6%. CONCLUSION: This study confirms that the face is a predilectionl site for PV in children and all facial lesions are hypopigmented. Other clinical features are variable and similar to those of adults.

We report a case of primary cutaneous cryptococcosis on Rt. forehead and perioral area of 57 year old woman with non-insulin dependent diabetes mellitus and Lt. cerebral infarction. She had large ulcers with yellowish purulent exudates on Rt. forehead and perioral area for 2months. A histopathological examination from the lesion showed numerous encapsulated, round spores and the organisms were identified as Cryptococcus neoformans in a series of fun-gal studies. The patient received a 5-week course of IV and oral fluconazole with resolution of her skin lesion. The patient is free of any lesion several months after completing therapy. This experience supports the use of fluconazole as initial and single therapy in primary cutaneous cryptococcosis.

OBJECTIVE: This study is proposed to examine the relationship between bone loss after hormone replacement therapy for one year and initial bone markers. METHODS: One hundred postmenopausal women were studied for one year. At first visit, measurements were made of bone mineral density(BMD) at the lumbar spine and femoral neck, and of serum osteocalcin and urine deoxypyridinoline. After hormone replacement therapy was done for one year, BMD was rechecked. RESULTS: Serum osteocalcin was correlated with the rate of bone change(r=0.150, 0.262) and urine deoxypyridinoline was weakly correlated(r=-0.003, 0.038). The changes of femoral BMD in women with higher concentration of osteocalcin and deoxypyridinoline were significant different from those in women with normal concentration. At the lumbar spine, no significant differences were showed. In women with higher concentration of osteocalcin, the incidence of subjects with increased spine BMD was increased up to around 71.1%, which showed not significant increase compared with normal concentration of osteocalcin. And the incidence of increased spine BMD in women with higher concentration of osteocalcin was marked increased compared with the incidence of normal concentration. The level of the osteocalcin with increased spine BMD was 11.5+/-6.6 ng/ml, and the level with decreased spine BMD was 9.2+/-4.7 ng/ml, respectively. And the level of the deoxypyridinoline was 7.2+/-4.2 pmol/ mol cr in women with increased spine BMD and 7.2+/-2.7 pmol/ mol cr in women with decreased spine BMD, which was not statistically different. The concentration of deoxypyridinoline with increased and decreased in BMD in spine and femur was not statistically different. but the concentration of osteocalcin was 12.2 +/-5.5 ng/ml in significantly increased in BMD and 8.5 +/-4.5ng/ml in significantly decreased in BMD, which was showed significant different. CONCLUSION: Present study indicates that the serum osteocalcin more reflcets bone turnover changes at the menopause than deoxypyridinoline, however, the clinical utility of measurements of osteocalcin only to response to therapy is uncertain.

To identify significant prognostic factors in patients undergoing simple hysterectomy in the presence of invasive cervical cancer, the records of 45 patients who had taken such a procedure between 1993 and 1997 were reviewed. Overall relapse-free survival and 5-year survival rates were 91.1 and 92.1%, respectively. Factors found to be significantly related to survival were the retrospectively determined stage(p=0.0000), the presence of residual disease(p=0.0001), and cell type(p=0.0000). By multivariate analysis, factor emerging as significantly detrimental to survival was the cell type. The presence of residual disease was a marginally significant factor(p=0.067). The expectations for survival of patients with residual tumor mass and/or with adenocarcinoma after simple hysterectomy appear to be markedly worse than those with others, so radical reoperation should be considered in those patients.

We tried to analyze the status of 10 units of frozen thawed apheresis platelet concentration by 6% DMSO method for the evaluation of practical applicability. The platelet concentrations were transferred to PL-732(Baxter, USA) cryopreservation bag, and DMSO is added to those bag at slow rate until expected final 6% concentration is achieved, thereafter those were directly placed to -80 degrees C refrigerator for freezing. Someday later from I week to 1 month, those were thawed at 37 degrees C water bath, and then washed by same volume of ABO matched plasma. In the course of cryopreservation, about 7% of platelets were lost and the mean recovery rate of platelet was 93% compared with those of unfrozen status. LDH, the values of platelet lysis, and pH were within normal limits, whereas platelet aggregation test shows decreased aggregation to collagen and ristocetine compared with those of unfrozen status(p<0.05) but they were clinically acceptable. We suggest that the frozen platelets may be useful in a some clinical situation such as hematologic malignancy and solid tumor by autologous transfusion.
