Reactive mesothelial cells are frequently found in the smear, of body fludid dffusion when associated with liver cirrhosis, pulmonary tuberculosis, congestive heart failure or pulmonary infarction. But it is not easy to differentiate these reactive mesothelial cells from macrophages or various types of malignant cells. In order to investigate the morphology of hyperplastic mesothelial cells, in comparison with the various types of malignant cells in the effusion, this experiment was designed. The tissue reaction was evoked by intraperitoneal injection of 2.5 ml of 2% Talcum suspension. The results obtained were as follows: 1) On light microscopic observation of the tissure, until 5 days, cytoplasm and nucleus of mesothelial cells became larger and nucleoi became prominent. After then, cytoplasm and nucleus became smaller and at 28 days after injection of Talcum suspension, cellular features became similar to those of normal ones. 2) On cytologic observation of touch print specimens, hyperplastic mesothelial cells became round to oval, and their cytoplasm became conspicuous. Nuclei were vesicular, and nucleoi were prominent. N/C ratio was decreased than normal. 3) On electron microscopic observation, hyperplastic mesothelial cells did not have microvilli, but had a few cytoplasmic globular projections, loosely approximated cellular junctions, larger and more abundant intracytoplaomic vesicles when compared with normal one. Chromatin clumping, irregular thickening of nuclear membrane and prominent nucleoi were also noted.
2.A Clinical Observation on l0 Cases of Anatrophic Nephrolithotomy.
Korean Journal of Urology 1987;28(6):808-814
The surgical intervention of renal staghorn calculi was performed in 9 patients(lOkidneys) who had undergone anatrophic nephrolithotomy with in situ hypothermia. admitted to the Department of Urology, HaniI Hospital, during four years periods from June, 1982 to May, 1986. This operation technique is simple, easy but uneventful recoveries followed only in a small group. The results were summarized as followings : l. Postoperative hospitalizations were 13.1 days(ranged from 8 to 21). 2. Operating time required 194.5 minutes with mean time(ranged from 150 to 230). 3. Renal artery clamping time required 36.4 minutes with mean time(ranged from 23 to 65). 4. Blood loss during operation was 875ml on the average loss(ranged from 350 to l400). 5. Postoperative complications were nephrectomy l case, pneumothorax l case, deep vein thrombosis l cases remained stone 3 cases.

It awakens interest that the frequency of carcinoma of the uterine cervix is the highest among the carcinomas among the Korean women, althouth it is not so high among Westerns. It is admitted that the exfolicative cytologic technique is useful not only as a screening test for early detection of cervical cancer and its precursor lesions but also as a tool for follow-up, because it is accurate, economical, and easy to perform. But it remains to be solved that the false negativity of the cytologic diagnosis is relatively high. Five hundred and sevently two cases of cytology specimens, confirmed by either colposcopic biopsy or cone biopsy, were studied among 15,844 cases which were submitted to the Department of Pathology, Chonnam University Hospital between October of 1982 and August of 1986. The results obtained were as follows. 1) The accuracy of the cytologic diagnosis was 69.9%, the false nagativity, 19.4% and the false positivity, 6.6%. 2) Among the causes of discrepancies between cytologic diagnosis and histologic diagnosis, error in cytology reading was the most frequent (57%), error in cell collection was the second frequent (43.7%), and error in biopsy location was the least frequent (5.3%). 3) Among the 38 cases of false positive diagnosis, the percentage of error in cytology reading was 82.3%, and that of error in biopsy location was 20.7%. Among the 105 cases of false negative diagnosis, the percentage of error in cytology reading was 50.5%, and the percentage of error in cell collection was 56.6%.

STUDY DESIGN: Retrospective study OBJECTIVES: This study examined the effect of a TLSO brace treatment for the correction of axial rotational deformities in idiopathic scoliosis. SUMMARY OF THE LITERATURE REVIEW: A TLSO brace treatment is effective in correcting 2-dimensional deformities of idiopathic scoliosis but is questionable in axial rotational deformities. MATERIALS AND METHODS: Fifty three cases treated by bracing in March, 1999~February, 2005 at our department were reviewed. The posteroanterior and lateral radiographs were checked in the standing position throughout the study. The change in axial rotational deformity were analyzed using Nash & Moe method and Perdriolle's method. RESULTS: The rotational deformity had improved in 2 curves, was aggravated in 8 curves, and showed no change in 43 curves with the TLSO brace. CONCLUSIONS: The TLSO brace treatment in axial rotational deformity of idiopathic scoliosis is not effective in correcting the rotational deformity but is effective in preventing the progress of a rotational deformity.

Condyloma acuminatum is a common viral disease which is transmitted by sexual intercourse. We experienced a case of condyloma acuminatum occurring in a patient of systemic lupus erythematosus who has been treated with various immunosuppressive agents for 10 years. This condylorna acuminatum was unusual in that it was very rapidly growing, recurrent and reluctant to various treatrnents. We investigated the type of human papillomavirus by Southern blot hybridization and schieved partial improvement by bleomycin intralesional injection together with 5-FU topical application.

BACKGROUND: Defective adhesion and migration of melanocyte may be involved in pathogenesis of vitiligo. Tenascin, a glycoprotein of the extracellular matrix, has a role in cell adhesion and migration. It has been reported that abundant expression of tenascin in vitiligo lesion may inhibit melanocyte adhesion and migration. OBJECTIVE: To investigate the tenascin expression in vitiligo skin lesions and to compare with clinical findings. METHODS: We studied 9 patients with vitiligo. The expressions of tenascin were studied by immunahistochemieal techniques.

We experienced a case of aeute cerebral infaretion after operation. A 74 year old female patient slipped down and received left femoral neck fracture. Preoperatively, orthopedist, internist and anesthesiologist visited and evaluated her but could not find any suspicious symptoms related to cerebral infarction. She have suffered from hypertension and diabetes mellitus for 1Q yrs. She underwent bipolar endoprosthesis under general anesthesia. Postoperatively, she became deep drowsy and revealed respiratory depression, abnormal neurological sign and was diagnosed as acute cerebral infartion on cranial computed tomography and ultimately expired.

Cystinuria is an autosomal recessive inherited defect in renal tubular reabsorption of four amino acids, cystine, ornithine, lysine and arginine. Homozygotes were identified by the formation of urinary tract calculi composed of cystine and by gross hyperexcretion of above mentioned four amino acids. Urinary tract calculi composed primarily of cystine are rare in adults and children. These are usually pure and found exclusively in patients with cystinuria. Herein we report on a 4 and 3/12 years old male child with a right renal stone composed primarily of cystine which was confirmed by chemical analysis method postoperatively. After discharge he has been treated with D-penicillamine, large fluid intake and conversion of urine pH.
