The clinical and mycological study was made with 38 cases of dermatophytoses in infants and preschoolers in dermatologic clinic of St. Pauls Hospital, Catholic Medical College, from September, 1982 to April, 1984. Following results are obtained: The incidence of dermatophytoses under the age 6 was 2. 2% among 1, 711 out- patients of the sarne age group. 2. The incidence of involving sites was the highest in tinea(T.) corporis(37. 2%) and T. faciale(37, 2%) and then T. capitis(18. 7g). In 0-under 2 groups, the highest incidence in T. corporis(54. 5%) and then T. faciale(3l. 8%.). In 4-under 5 group, the highest incidence in T. capitis(55. 6%). 3 Fungi cultured from their skin lesions were 36 strains belonging to 6 species. These were M. canis(55. 6%), T. rabrum(27. 8%), granular type of T.mentagrophyte(8.3%) and interdigital type of T. mentagrophyte(27. 8%), M gypseum (2.8%). and E. floccosum(2.8%) in order. 4. Arnong 1Q strains of T. rabrum, anthropophilic fungi, 8 strains(80. 0%) were frorn 0-under 2 age groups, E. floccosum, and interdigital type of T. mentagrophyte were also from 0-under 1 age group. Among ZO strains of M, canis, zoophilic fungi, 13 strains(65. 0%) were from the age groups of 2-under 5. Granular type of T. mentagrophytc, 2 among 3 strains were from 4-under 5 age group, 5. The incidence of causative fungi in each sites were as follows: In T. corporis, T. rubrum(50. O%), and M canis(18. 8%) in order. In T. faciale, M. canis(62. 5%), T. rabrum(12. 5%), T. mentagrophyte(12. 5%), and M. gypseum(6. 3%) in order. In T. capitis, all cultured fungi were M. canis

Fibrous histiocytoma composed of fibroblasts and histiocytes is quite variable in histologic pattern. The biologic behavior is unpredictable by histologic ground. This tumor is well-known in subcutaneous tissue and deep soft tissue, but quite rare in central nervous system. We experienced a case of the fibrous histiocytoma involving the dura mater of spinal cord in a 26 year old female patient. In gross findings, the mass was a well demarcated, ovoid mass attached to the dura matter, and measured 2.5x1.5 cm in diameter. The cut surface was rubbery, solid, gray-white or yellow. Microscopically, the lesion consisted of polyhedral cells with round or oval nuclei and faintly eosinophilic or vaculoated cytoplasm, and multinucleated giant cells. Some giant cells were Touton-type. Composing cells were bland-looking. Mitotic figures were average 3 per 10 high power fields.

As measurement of glomerular size in the assessment of several renal diseases becomes increasingly important, it has become necessary to devise rapid simple methods for the assessment of glomerular size and to have on hand reference ranges. A few reports on glomerular size have been published in Western literature, but their body builds are different from Koreans. In this study, 100 glomeruli(50 glomeruli each from the outer cortical and the juxtamedullary area) were measured in sections taken from 74 kidneys(ages 3 days~73 years) obtained from autopsy utilizing the semi-automatic image analyser. The percentage of glomerular sclerosis was measured based on its location. The sphere diameter, maximum diameter, area and sphere volume of non-sclerotic glomeruli were measured and evaluated with respect to age, sex and the location of the glomeruli. The results were as follows; 1) Mean glomerular dimensions including sphere and maximum diameter, area and sphere volume increased until 40 years of age, then reached a plateau. The percentage of sclerotic glomeruli then increased slowly with age but without statistical significance. 2) The glomerular dimensions and sclerosis showed no significant differences according to sex. 3) Juxtamedullary glomeruli were larger than the outer cortical ones which was statistically significant in age groups of 0~10, 11~20 and 41~50 years. The percentage of sclerotic glomeruli was generally greater in the outer cortex. 4) Differences in the values of glomerular dimensions between outer cortical and juxtamedullary area were similar in all age groups. 5) All parameters of measurement showed consistent and similar trends between the different groups. 6) The measurements of the largest 12 glomeruli out of randomly-selected 50 glomeruli gave similar results when compared with those of 50 glomeruli. It was evident from our results that glomerular size is influenced by age and glomerular location, but not by sex. The method of assessing glomerular size used in this study will not necessarily give the true, absolute value of size but it may be a simple, practical and useful method of comparing glomerular size in different groups of patients.

The clinical and pathological features of a case Malignant mixed mullerian tumor of the ovary in 45 year-old female patient with a brief review of the literature are presented. She had both ovarian tumors. The masses are multilocular cystic tumor with interspersed solid component. The cystic component is filled with serous fluid. Microscopically the tumor is composed of epithelial element & intimately related mesenchymal element. The epithelial element shows the findings of adenocarcinoma of solid, glandular and papillary growth. The mesenchymal element is composed of malignant-looking stroma with cartilage formation.

To know the correlation between glomerular and tubulointerstitial lesion and to define the characteristics of interstitial inflammatory cell in IgA nephropathy and classified according to WHO classification and graded tubulointerstitial lesion as mild, moderate and severe. Paraffin-embedded 5u sections were stained with UCHL-l, L26 and CD68 antibodies. More than 20 fields were examined in each case under the high power microscopy and the number of positive cells were counted. There was positive correlation between the severity of glomerular and that of tubulointerstitial lesion. The mostcommoninflammatory cells in the interstitiuin were UCHL-l positive cells followed by CD68 and L26 positive cells. As the WHO grade or tubulointerstitial lesion increased, the numbers of positive cells were increased in all three groups. The proportion of UCHL-1 Positive cells were increased in cases with high WHO grade whereas that of L26 positive cells incases with severe tubulointerstitial lesion Proteinuria was correlated with the degree of inflammatory cell infiltration, especially with that of L26 positive cells.

At first, we review a sample size estimation method for log-rank test in survival analysis. Although it is widely used these days, it has a weakness for practical use. We propose a modification method to avoid the weakness.

Botulium toxin A has been used therapeutically in humans for over 20 years for a variety of medical indications. Some wrinkle and unsightly facial expressions are due to hyperkinetic muscle. For the past year, the author has injected it for variant purpose, so we describe the our experience with the variant extended use of the toxin including correction for just dynamic wrinkle, used with subperiosteal face lifting or peeling, post-traumatic twitching, and facial paralysis and relevant anatomy are discussed. Also we have another concept about muscle anatomy which have superficial and deep portion. The superficial portion is for harmonious action with SMAS during facial expression, which is also related to fine wrinkle, and the deep portion play role gross movement. Botulium toxin is safe and effective in varient field without complication. Its use is associated with a high degree of patient and physician satisfaction.
