The meniscus has improtant functions of shock absorption, load transmission, lubrication and significant contribution to stability of the knee. Accordingly, repair rather than excision can be expectd to be satisfactory and functional teatment for knee joint. We had Repaired 56 cases of meniscal tears from March, 1987 to September of 1992, among which 42 cases were followed up for at least 12 months to 60 months at most(in average 36 months). The results were as follows; 1) In medial meniscal tears, 26 cases were acute, while five were chronic. As for the lateral meniscus, acute and chronic teats were observed in nine and two cases, respectively. 2) Eleven of the 35 acute tears were associated with anterior cruciate ligament tears, while three of seven chronic tears were associated with anterior cruciate ligament tears. 3) Second-look arthroscopic examinations were performed on nine repaired cases. Retears occurred in two cases and seven cases revealed healing at repair sites. 4) Two cases(5%) out of 42 repaired menisci were return during follow-up. One was a case of isolated meniscal tear and the other was associated with rupture of anterior cruciate ligament. 5) Two return cases were repaired in the chronic stage of more than one year after trauma. 6) The standing radiographs which were taken in full extension and 45 flexion on eight out of 13 patients, who had been followed up for more than 4 years showed intact joint space without narrowing.

Apoptosis is an intrinsic and fundamental biological process that plays a critical role in the normal development of multicellular organisms and in maintaining tissue homeostasis. Some of the well known regulators of apoptosis are cytokines of the tumor necrosis factor(TNF) ligand family, such as Fas ligand(Fas L) and TNF, which induce apoptosis by activation of their corresponding receptors, Fas and TNFR-1. Recently, a new member of the TNF family known as TRAIL (TNF-related apoptosis-inducing ligand) was identified and shown to induce p53-independent apoptosis in a variety of tumor cell lines but not in normal cells, Four human receptors for TRAIL were also recently identified and designated TRAIL-R1, -R2, -R3, and -R4. The aim of this study is to examine whether TRAIL and TRAIL receptots(-R1, -R2, -R3) are expressed in uterine cervical cancer and whether it is correlated with apoptosis, TRAIL and TRAIL receptors. The subjects were 20 patients who were diagnosed with cervical cancer. Western blotting was performed in 9 cases, immunohistochemical staining for TRAIL and TRAIL receptors(-R1, -R2, -R3) and TUNEL method for detection of apoptosis in 11 cases. There were proteins for TRAIL, TRAIL-R1, -R2, and -R3 in tissues from cervical cancer. All TRAIL receptors were expressed in both normal cervical epithelium and tumor cells, and TRAIL-Rl and -R2 were more strongly expressed in tumor cells than normal epithelium(p<0.05). Apoptosis correlated with expression of TRAIL-Rl and -R2(p<0.05). This study suggests that TRAIL induces apoptosis in cervical cancer through its receptors.

PURPOSE: Recently, there are many good reports on the arthroscopic management of tibial condylar fractures. But, it may be appropriate for selected tibial condylar fractures and also needs a skilled technique. So we report the results of the tibial condylar fractures treated by the arthroscopy and limited percutaneous fixation or the arthroscopic-assisted management with conventional internal fixation without arthrotomy. MATERIALS AND METHODS: From June 1996 to December 1997, we treated 22 cases of the tibial condy- lar fractures including relatively comminuted one and analysed the results of patients who have been observed at least 1 year with Porters knee evaluation criteria. RESULTS: In 18 out of 22 cases, the results were Acceptable on symptoms(excellent 3, good 15, fair 4), in 18, on function(excellent 10, good 8, fair 3), in 21, on appearance(excellent 12, good 9, fair 1) and in 20, on radiographic appearance(excellent 11, good 9, fair 2). Overall results were Acceptable in 18 cases(82%) and Unacceptable in 4 cases(18%). CONCLUSION: The arthroscopic-assisted management with conventional internal fixation without arthrotomy can be the recommendable treatment for the tibial condylar fractures, including relatively comminuted one, without complications.

This study was carried out to investigate the heavy metal contents and their correlations between paddy soil and brown rice near the Kum-River area. In this study, eighty soil samples and forty brown rice samples were taken from the paddy soil. The contents of heavy metals were measured by flame atomic absorption spectrophotometry. The results were as follows: 1. The average contents of soluble heavy metals in surface soil were Cd 0.19, Cu 15.31, Zn 18.10 and Pb 9.08 ppm. The average contents of soluble heavy metals in subsurface soil were Cd 0.19, Cu 14.52, Zn 17.75 and Pb8.11 ppm. There wan no statistically significant difference between the two layers. 2. The contents of Cu, Zn and Pb of Taejeon(S6) and Cd of Sinbyung(S5) in surface soil were higher than those of other areas. The contents of Cd and Cu of Taejeon(S6) and Zn and Pb of Kumnam(S3) in brown rice were higher than those of other areas and four heavy metals in soil and brown rice of Simchon(S7) were lower than those of other areas. 3. The ratio of soluble contents(Cd : Cu : Zn : Pb) in surface soil was 1 : 79 : 93 : 47, that of soluble contents in subsurface soil was 1 : 79 : 94 : 43, and that of total contents in brown rice was 1 : 84 : 294 : 12. 4. The correlations of the content between soluble heavy metals in surface(0-15 cm depth) soil total heavy metals in brown rice was found to be order of Cd>Cu>Zn>Pb. The correlations of the content between soluble heavy metals in subsurface(20-30 cm depth) soil and total heavy metals in brown rice was found to be order of Cu>Cd>Zn>Pb.

The distribution of pemphigus subclass autoantibodies in a patient with pemphigus vulgaris (PV) has been investigated by semiquantitative indirect immunofluorescence (IIF), using the HP series monoclonal antibodies specific for four human IgG subclasses on human foreskins. IgG1 and IgG4 intercellular substance-specific autoantibodies were detected in the serum of the patient, whereas IgG2 and IgG3 autoantibodies were absent. In addition to foreskins, human tonsillar epithelia were used as substrates of IIF for detecting the PV autoantibodies and it was one of satisfactory substitutes for monkey esophagus.

Pheochromocytoma originate from chromaffin cells and occur in the adrenal medulla in majority. About 10 per cent of pheochromocytomas can occur in the ectopic or extra-adrenal sites, anywhere along the fetal route of the chromaffin tissues. Pheochromocytoma of the bladder is a rare neoplasm that often occurs with the unique symptom complex of micturitional attacks, such as headache, palpitation, hypertension of sweating due to increased catecholamine secretion during detrusor activity. We report a very rare case of nonfunctioning pheochromocytoma of the bladder in a 67- year-old woman without typical symptoms. Preoperatively elevated urine catecholamines and their metabolites returned to normal after removal of the tumor.

Colorectal cancer during pregnancy is rare but the trend for women to delay pregnancy until later in life may result in increased incidence of colorectal cancer during pregnancy. The most common symptoms are rectal bleeding, abdominal discomfort, abdominal distension, anorexia, nausea, vomiting, constipation, anemia and weight loss. Rectal bleeding, if it is occurred, is often attributed to hemorrhoids, a common finding of pregnancy and many of these symptoms are commonplace in normal pregnancy. This delays diagnosis of colorectal cancer during pregnancy and leads to more advanced stage and poor prognosis compared to the general population. We experienced a woman at 27 weeks gestation who complained of low abdominal distention and was diagnosed of sigmoid colon cancer and underwent cesarean section and hemicolectomy at 30 weeks gestation, so we present it with brief review of literature."

Sister chromatid exchanges (SCEs) observed by means of bromodeoxyuridine substitution and fluorescence plus Giemsa (FPG) technique were proposed as a sensitive and quantitative assay for mutagenicity and cytotoxicity in short-term cultures of phytohaemagglutinin (PHA)-stimulated human lymphocytes. Therefore, this study was carried out to investigate the relation between anticancer agents and cytotoxic effects. Chromosomal analysis was performed on metaphase cells that had divided one, two, or three or more times after treatment for SCEs, mitotic indices (MI) and cell cycle kinetics by FPG technique. The results indicate that anticancer agents led to a dose dependent increase in SCE frequency except methotrexate. But, highly inhibited mitotic indices and delayed cell cycle kinetics were observed except for cyclophosphamide. The author suggest that the difference of SCE frequency is due to the differences in the cytotoxic action of anticancer agents, but although the induction of SCEs has a correlation with cell cycle delay, in some cases the induction of SCEs is not always related to cell cycle delay because of different cytotoxic action of anticancer agents.

Congenital scoliosis is defined as a lateral curvature of the spine caused by congenital anomalies of the vertebral development. In this study seventeen congenital scoliosis patients seen and treated by either Milwaukee brace or surgical intervention at Department of Orthopedic Surgery, Seoul National University Hospital from December 1972 to April 1978 were evaluated according to frequency of the curve pattern, character of the deformity, method of treatment and its correctability. The following results were obtained in this study. 1. Age distribution was from 2 to 39 years and mean age was 13.4 years. 2. The most common deformity pattern was hemivertebra in 8 cases (47.1%), unilateral unsegmented bar in 4 (23.6%) and mixed type in 3 (17.6%). 3. The most common curve level was thoracic in 6 cases (35.3%), followed by thoracolumbar in 4 (23.5%) and lumbar in 4 (23.5%). 4. The best corrected type by Milwaukee brace was trapezoid vertebra (29.4%) and then mixed type(26.1%), followed by block type (20%) and hemivertebra(2.3%). 5. The operative treatment was performed in the cases of unilateral bar and progressive type with Milwaukee brace. In terms of the correctability of the curvature, the surgical intervention was better than the conservative treatment, with the result of its average correction of 33.5% that is compared with 15.9% of Milwaukee brace. 6. Halofemoral traction was effectively applied in the cases of rigid and severe curve; the initial curve 76.3 degress with 21.3% of flexibility. 7. Loss of correction in operative treatment was 2.3 degrees (6.5%).
