Adenocarcionma of fetal type is in lung is a newly recognized malignant tumor sharing morphologic features with the epithelial component of the pulmonary blastoma devoid of sarcomatous component. We present a case of adenocarcinoma of fetal type in a 28-year-old female, consisting of numerous branching tubules or glands and morula-like epithelial complexes. Histologically, the tubules and glands were composed of glycogne-rich nonciliated epithelial cells showing in part argyrophilia. Some of tubular and morula-like epithelial cells revealed immunoreactivity for neuron-specific enolase. We report this case with a review of literatures with special references on the histogenisis. This report is the pathologically confirmed second case of the pulmonary adenocarcinoma of fetal type in Korea, following the report of Cho and Lee, 1990.

The authors report a case of uterine tumor resembling ovarian sex-cord tumor in a 31-year-old woman with emphasis on immunohistochemistry. Histologically this case showed identical features to a well-recognized endometial stromal tumor except for focal epithelial-like differentiation that resembled sex-cord tumors of the ovary. The sex-cord like differentiation of tumor cells were manifested by trabeculae, plexiform cords, and gland-like pattern. We diagnosed this case, according to the features described by Clement and Scully(1976), as uterine tumor resembling ovarian sex-cord tumor, group I. Although the histogenesis of this tumor is unclarified, most authors believe that this tumor may be originated from multipotent mesenchymal cells of the uterus. On immunohistochemical stains, Desmin was uniformly reactive in epithelial-like cells and in focal areas of endometrial stromal sarcoma-like component. Vimentin was partly reactive in all tumor components, however EMA was non-reactive.

Syphilis is a communicahble disease caused by the motile microaerophilic spirochete Treponema pallidum, which is only a netural pathogen for human. Prevalence of syphilis and other sexually transmitted diseases has traditioially fluctuated with changes in sccia, conditions and sexual behavior. Although sexual contact is the main route of transmission, T. pallidum may also be infected through direct contact with syphilitic lesions, blood transfusion, ingestion of menstrual blood or vaginal secretions, or trsnsplacental transemission. Fomites as the means of transfer is only hypothetical and account for very few, if any, infection. Prosectors, blood handlers and laboratory technicians are at risk for accidental inoculation with infected materials. In extremely unusual circumstances, infection by means of contact with a skin lesion and human bite have been reported. We report two cases of eyphilis following the abnormal imposition of hands, which caused unnecessary erosive trauma with fingernails,

The morbidity of spondylolisthesis tends to increase in accordance with the popularization of sports and increase of mean life span by the development of medicine. We had applied surgical treatment for 39 cases of spondylolisthesis during the period of 8 yrs. from Jan. 1976 to Dec. 1983 at Department of Orthopaedic Surgery, National Police Hospital, among them 35 cases were followed up for mean 27 months. Twenty eight cases with posterolateral spinal fusion were isthmic spondylolisthesis and seven cases with posterior spinal fusion and facetectomy were degenerative type. We analysed them with clinical aspects and surgical treatment for 35 cases. The results were as follows: 1. The most common clinical symptoms were low back pain (96.7%) and tenderness (93.5%). 2. The degree of slipping was Grade I by Meyerding's classification in all cases and mean 12.5% by Taillard method. 3. In the 7 cases of isthmic spondylolisthesis, the degree of slipping increased on standing lateral view. And in these cases the clinical symptoms were aggrevated at welking. 4. In the degenerative spondylolisthesis with posterior spinal fusion and facetectomy, we found mean 70% spontaneous correction of slipping commpared with preoperative. 5. In postoperative evaluation we gained 94.3% above good according to Gill's criteria and no pseudarthrosis.

PURPOSE: Many investigators suggested that changes in hormonal environment in the postmenopausal women functionally or histologically effect the clitoris and vagina. We investigated the mechanism of female se xual dysfunction occurring in the decreased hormonal status, and aimed to establish and experimental base for the hormone replacement in postmenopausal women to correct sexual dysfunction. MATERIALS AND METHODS: Twenty mature female New Zealand white rabbits were randomly divided into three groups; control group, oophorectomy group, estrogen replacement group after oophorectomy. Nitric oxide synthase (NOS) activity and the degree of expression of neuronal NOS (nNOS) and endothelial NOS (eNOS), collagen content in clitoral tissues were analysed. RESULTS: nNOS and eNOS were significantly increased in the oohporectomized group while decreased in the estrogen replacement group (p<0.01). NOS activity showed the similar pattern of change (p<0.05). Oophorectomy induced a significant increase in collagen content, while the ratio of smooth muscle content was increased significantly after the estrogen replacement (p<0.01). CONCLUSIONS: Estrogen deficiency induces collagen synthesis and decreases the content of smooth muscle in clitoris, resulting in a structural relaxation difficulty. We believe that NOS becomes more active to improve the relaxation difficulty and that hormone replacement helps to restore the normal state of smooth muscle relaxation. Considering these findings, we suggest that estrogen down-regulates NOS and its activity.

The relationship between the serum values of prostate-specific antigen (PSA) and the histologic composition of benign prostatic hyperplasia (BPH) was investigated in 32 symptomatic BPH patients undergoing transurethral resection of the prostate. We evaluated the free and total PSA concentrations by ACS-PSA2 (Ciba-Corning) assay. The stereological analysis was made by computer aided-area densitometry using H & E stained slides to quantify stromal and glandular areas in the resected prostate tissue. The total PSA concentration versus percentage of glandular area (%G) and stromal-glandular ratio (SGR) correlated significantly (p<0.05 for both) whereas the free PSA concentration and free/total PSA ratio did not (p>0.05 for both). These data suggest that total PSA is directly correlated with the histologic composition of the prostate in men with BPH, however, the proportion of free to total PSA was not informative to predict the histology. Thus, pretreatment evaluation of total PSA would be useful as part of an evaluation method of BPH for medical therapy.

Clinical observations were made on 349 cases of acute drug intoxication who were visited to emergency room of Yeungnam University Hospital during recent 7 years from January 1984 to December 1990. The following results were obtained. 1) Total number of cases of acute drug intoxication was 349 which was 0.39% of the total patients of the emergency room during the same period. 2) The ratio of male to female was 1.1:1. The age incidence was highest in the third decade (26.7%). The monthly incidence was highest in May. Higher frequency was observed in summer season. 3) The most common drug of the intoxication was pesticides and herbicides (71.9%), the remainders were miscellaneous drugs (11.2%), sedatives (7.7%), rodenticides (6.3%) and unknown drug (3.2%) in orders. 4) The most common cause of drug intoxication was suicide (69.1%) and the others were accident, unknown cause, intention in orders. 5) Main clinical manifestations were the impairment of consciousness, nausea, vomiting and convulsion. Physical examination revealed increased pulses, increased blood pressure, miosis of the pupil and sweating. Above symptoms and signs were more prominent in pesticide intoxication. Leukocytosis, glycosuria and abnormal LFT were common findings in acute intoxications. 6) The complications were developed in 18.3% among 349 cases and the most common complication was respiratory failure, pneumonia, cardiovascular collapse and pulmonary edema in orders. 7) Overall mortality rate was 8.3% of total cases and mortality rate was highest in herbicide intoxication (22.2%).

The purpose of this study were to determine that dexamethasone(Dex) induces differentiation of periodontal ligament(PDL) cells to osteoblastic cells and to investigate expression of matrix Gla protein(MGP), which is one of bone matrix protein. The isolated human PDL cells and gingival fibroblasts were prepared and cultured. The fourth or sixth subpassage cells were used in this experiments. control group, ascorbic acid and beta-glycerophosphate treated group, ascorbic acid, beta-glycerophosphate and 100nM Dex treated group, ascorbic acid, beta-glycerophosphate, and 5micrometer Dex treated group were made for study. The results were as follows: Cellular morphological change of PDL cells according to time was investigated. At first, the cells exhibited confluent monolayer of spindle or polygonal appearance. The multilayer of cells were seen after 7 days of treatment. After 14 days, the cells lost polarity and were densely packed. The mineralized nodule formation was seen at 21 days in the only Dex treated PDL cell groups. In the gingival fibroblast groups and no Dex treated PDL cell groups, the mineralized nodule was not seen. The mineralized nodule formation of 5micrometer Dex treated group was higher than 100 nM Dex treated group. Alkaline phosphatase(ALP) activity was higher in the Dex treated PDL cell groups of 14 and 21 days than 0 and 7 days. MGP was expressed in the control and all experimental groups and the expression was constant at 0, 7, 14, 21 day. The above results confirm that Dex is affected to differentiation of the PDL cells to osteoblastic or cementoblastic cells and has dose-dependent effect for mineralization. And, MGP is expressed in the PDL cells and is not affected to mineralization of PDL cells.

For young children with scoliosis before growth spurt, suhcutaneous lengthening without fusion was designed by Harrington and modified by Moe and Luque. However, many problems including spontaneous fusion, rod breakage, and hook disloclgement have been ohserved. CotrelDubousset(CD) instrumentation was sometimes used, but it usually resulted in failure due to soft tissue adhesion around the rough surface of ordinary CD rod. We tried to use the smooth CD rod, transvcrse-pedicle clawing on the upper part, and pedicle screw inscrtion on upper and lower part of the curve to reduce the hardware failures. Among 8 patients in whom suhcutaneous lengthening with smooth CD rod was carried out hetween October l992 and Suly 1996. 4 cases perfomed with final spinal fusion were analysed. There were I central core disease, 1 multicore disease and 2 idiopathic scoliosis(infantile and juvenile type). Mean age at the first operation was l0.0(8.8-11.8) years, and the Risser sign was all grade 0 except one with grade 1. Suhcutaneous lengthening was performed every 5 or 6 months Mean lengthening duration was 22(9-39) months and mean age at spinal fusion was 11.7(9.6-13.8) years. Mean Cobb angle decreased from 7ldegrees (55degrees-88degrees) at preoperative stage to 32 (10degrees-59degrees) at the last follow-up. There were 5 complications during 21 operations, and three hardware failures comprised 2 hook dislodgcment and 1 screw pull-out. Crankshaft phenomenon happened in I case who had had a posterior fusion in young age(9.6 years) due to laminar fracture. The suhcutaneous lengthening with smooth CD rod can he another option of treatment for young children with severe scoliosis. prescrving the powth potential of involved vertebrae with few complications.
