OBJECTIVES: The purpose of this study was to get help in order to diagnose orthopaedic disease, measure its activity and determine treatment plan by measuring the beta-glucuronidase activity in urine, serum and joint fluid. METHODS: The beta-glucuronidase activity was determined in the serum, urine and joint fluid of the patients with degenerative arthritis, rheumatoid arthritis, osteomyelitis and osteogenic sarcoma, and some other disease to study the change of the enzyme activity. These values of each specimen were calculated by standard curve and treated by statistical analysis. RESULTS: The results obtained were summarized as follows. 1. The beta-glucuronidase activity in the serum, urine and joint fluid was increased in patients with degenerative arthritis, rheumatoid arthritis, osteomyelitis and osteogenic sarcoma etc. 2. The increased beta-glucuronidase activity in the serum and joint fluid of each disease does not show a specific finding about respective disease, but the increased beta-glucuronidase activity was statistically significant in the urine of all disease groups(male:p=0. 0041, female:p=0. 0001). CONCLUSIONS: On the basis of these results, it was suggested that beta-glucuronidase activity was affected by the orthopaedic disease and differed according to each specimen.

The nm23 gene was originally identified from murine melanoma cell lines of varying metastatic potential. A strong association has been observed between reduced expression of nm23 gene and acquisition of metastatic behavior in some tumor cells including breast cancer and melanoma, but not in others such as colon cancer, neuroblastoma, and cervical cancer. It was proposed that nm23 may function as a suppressor gene for tumor metastasis. It has recently been found that the sequence of nm23 and NDP-kinase(NDP-K) was identical. Mortality associated with human breast carcinoma is almost entirely due to subsequent metastasis, but the molecular basis of this metastasis is not understood. Elucidation of the genetic control of metastatic propensity of a tumor is important in determining prognosis and choice of therapy. The purpose of this study was to investigate the relationship of nm23 protein expression with axillary lymph node metastasis and other prognostic factors. Using an immunohistochemical technique and employing a polyclonal antibody to nm23 protein, we have determined nm23 expression in a series of 72 infiltrating ductal carcinomas of the breast. Immunostaining for the nm23 gene product have heterogenous cytoplasmic and nuclear staining in 61 patients(84.7%). Sections were scored according to relative abundance(1 = less than 25% of the cells, 2 = 26-75%, 3 = 76-100%). In 61 patients with positive immunostaining, the staining was scored as 1 in 41.6%, 2 in 18.0%, and 3 in 40.2%. The staining of tumor cells was greater than that in normal epithelial cells and stromal cells. No relationship was found between nm23 expression and lymph node metastasis, histologic grade, tumor size, estrogen receptors or progesterone receptors. Therefore, nm23 protein is increased in neoplastic tissues but no correlation with metastatic potential could be demonstrated. The biological mechanism of over-expression of nm23 in malignant cells and its role in tumor progression remain to be determined.

The most common cause of small bowel obstruction is postoperative adhesion, and besides a hernia, metastatic or primary cancer and small bowel tumors are possible causes. Superior mesenteric artery (SMA) syndrome is a rare cause of upper gastrointestinal obstruction and is associated with debilitating conditions with marked weight loss. SMA syndrome results from the compression of the third part of the duodenum due to the narrowing of the aortomesenteric angle. We report a 28-year-old woman with SMA syndrome after acute gastroenteritis. Her stomach was severely dilated due to the duodenal obstruction and computed tomography showed the compression of the third portion of the duodenum by SMA. She was conservatively cared for and thus favorably improved.

The purpose of this study was to clarify the histologic changes in the expansion of midpalatal suture by the tensile forces. 39 Sprague-Dawley rats were divided into a control group (3 rats) and three experimental groups (36 rats)-group 1, pressured with a light force (50-75g), group 2, with a heavy force (250-300g) and group 3, with a heavy force (250-300g) plus laser irradiation. Autoradiographic and histopathologic observations were performed in 12, 24, 48 and 96 hours after force delivery. The results were as follows: 1. The anterior portion of midpalatal suture was more separated than the posterior portion in all experimental groups. Group 2 showed more separation than group 1 and no difference to group 3. 2. Ligament tearing appeared intensively in 24 hours, but the sutural matrices increased with times.: Group 2 showed more tearing than group 1, and active regeneration of sutural matrices was observed in group 3. 3. Vascular dilatation appeared intensively in 24 hours and decreased with times. : The anterior portion of midpalatal suture showed more dilatation than the posterior portion.: The changes was the greatest in group 3, group 2, group 1, in that order. 4. New bone formation and the new capillary prolieferation began to appear in 12 hours and increased with times.; Group 2 showed more changes than group 1 and no difference to group 3. 5.

Rheumatoid arthritis is a chronic inflammatory systemic disease of young or middle aged adults, characterized by destructive and proliferative changes in the synovial membrane, periarticular structures, skeletal muscle and perineural sheath. Eventually, the joints are destroyed, ankylosed and deformed. Therfore, the aim of treatment is to keep the inflammatory process at a minimum, thereby preserving the joint motion, maintaining the health of muscle supplying motor power about the joint and preventing secondary joint stiffness and deformity. Surgical treatment in rheumatoid arthritis has progressed and there have been advances in the relief of pain and increase in the range of motion. Among them the results of total knee arthroplasty (TKA) have improved steadily during the past decade due to refinements in design, fixation, and surgical technique. At orthopedic department of seoul national university hospital, we performed 31 total knee replacement in 18 patients who had suffered from rheumatoid arthritis during the period from Aug. 1982 to Dec. 1988. Following results were obtained. 1. Knee score increased from 37.8 to 76.9. 2. Tibio-femoral angle was corrected from 0.9° valgus to 5.3° valgus. 3. Conplications were peroneal nerve palsy in 3 knees, instability in 1 knee, tuberculous arthritis in 1 knee. 4. In 25 out of 31 knees, good functional results were obtained.

BACKGROUND: Calcium channel blockers and volatile anesthetics have depressant effects on cardiac function. Both of them appear to exert, qualitatively and quantitatively, different effects on myocardial contractility, coronary flow, and myocardial oxygen balance. The aim of this study was to examine the direct cardiac effects of the enflurane in the presence of diltiazem. METHODS: Isolated Sprague-Dawley rat hearts (N=45) were perfused at constant pressure with oxygenated Modified-Krebs solution (pH 7.4, 37oC). Isovolumetric left ventricular pressure (LVP) and dP/dt were measured via a latex balloon and transducer. Also, coronary flow and oxygen tensions at the coronary inflow and outflow were measured. After stabilization period, all hearts were subjected to the application with diltiazem (100 ng/ml). Thereafter, they were subdivided into three groups; group 1, 2, 3. Groups subjected to the combination of diltiazem (100 ng/ml) with enflurane 1.1, 2.2, or 3.3 vol%, respectively. RESULTS: After the application of diltiazem, myocardial contractility and heart rate were significantly decreased, and coronary flow were significantly increased. The combination of diltiazem with enflurane depressed myocardial contractility, heart rate, myocardial O2 consumption, and percentage of O2 extraction more than diltiazem alone, and their effects were dependent on the concentration of enflurane. However, there was no difference in the change of coronary flow and oxygen delivery between diltiazem and the combination of diltiazem with enflurane. CONCLUSIONS: These in vitro findings demonstrate that the combination of diltiazem with enflurane shows greater direct negative inotropic and negative chronotropic effect, and is associated with less attenuation of coronary autoregulation, but with a larger reduction in O2 utilization. The present results suggest that high enflurane anesthesia in the diltiazem-pretreated patients could result in profound cardiac depression.
