Since introduction of venous flap in 1980, many experimental studies and clinical applications of various kinds of venous flaps were reported. Venous flap has the following advantages : (1) nonbulky and goo-quality of flap (2) long & large vascular pedicle (3) easy & rapid elevation of flap (4) no sacrifice of major arteries (5) a single operative field. But, we also have some disadvantages of difficult handling of the pliable veins and the tmcertainty of flap survival. For the better result we had to design the size of the flap larger than that of defect and increase the number of draining vein to reduce the postoperative edema of the flap. We have treated the defects of soft tissue of the hand using free arterialized venous flap from the flexor aspect of the forearm & had an excellent results.

OBJECTIVE: The purposes of this study were to observe the radiographic changes of lumbar facet joints by magnetic resonance imaging (MRI) in conservatively and operatively treated groups of patients with herniated intervertebral disc, and to compare the biomechanical effects to lumbar facet joints according to the treatment methods. METHOD: The patients composed of 20 conservatively treated control group and 40 operatively treated group who had disc herniation at lower lumbar spine. Follow-up MRIs were performed in order to assess the radiographic changes of intervertebral disc and lumbar facet joints, such as disc degeneration, lumbar facet joint angle and tropism in either treatment groups individually. RESULTS: There are significant increase in lumbar facet joint angle in operatvely treated group at the level of both L4/5, right L5/S1 compared to that of conservately treated group, but the disc degeneration and facet joint tropism were not changed after treatment in both groups. There's no relationship between treatment period and each parameters. CONCLUSION: The radiographic biomechanical lumbar facet joint changes on MRI seems to be related to degenerative change of lumbar facet joint in operatively treated group with a lumbar disc herniation. Therefore, careful selection of optimal operation time and criteria would be important.

Computerized tomography has been used in the evaluation of the intracranial lesions. Recently the usage of computerized tomography has progressively widened in many fields of clinical practice. In orthopedics computerized tomography has been tried in the diagnosis and the determination of treatment of tumors, spinal disorders, hip disorders and knee problem. Four problem cases in which concentric reduction could not be obtained after closed reduction of hip dislocations were evaluated by computerized tomography from Apr, 1, 1983 to Mar. 31, 1984 in the Capital Armed Forces General Hospital and following conclusiions were obtained: 1. Open reduction revealed that muscles(adductor and pyriformis muscles), joint capsule and osteocartilaginous loose bodies (femoral and acetabular) were interposed to hinder concentric reduction. Large posterior acetabular fragment induced instability and redislocation of the hip. 2. When there were 2-3 mm lack of symmetry of the two femoral heads or any abnormal findings(breakage of Shenton's line etc.) in plain roentgenography, computerized tomography was recommanded, and muscles, osteocartilaginous loose bodies and instability were found. 3. Computerized tomography is an easy simple method and has a great diagnostic value in the evaluation of asymmetry and instability after closed reduction of traumatic hip dislocations.

PURPOSE: In rectal cancer, it is known that the postoperative radiotherapy is an effective way for reducing locoregional recurrence, especially if accompanied with concurrent chemotherapy. However, toxicity to small bowel was one of the major limitations to perform full-dose radiotherapy. For overcoming this problem, abdominopelvic omentopexy, which separates the small bowel from the pelvic cavity, was developed. This study analyses the acute and chronic complications related to the partitioning of the pelvic cavity and subsequent postoperative radiotheraphy. METHODS: From January 1990 to September 1999, medical records of 127 patients with rectal cancer who underwent abdominoperineal resection were retrospectively reviewed. Seventy-one of these patients belonged to stages B2 through D according to the modified Astler-Coller classification and underwent adjuvent chemoradiation therapy, and abdominopelvic omentopexy was performed in thirty- three patients. We compared postoperative radiotherapy complications between abdominopelvic omentopexy group and non-abdominopelvic omentopexy group. After abdominoperineal resection, the greater omentum covers whole small bowel like apron. The lateral edges are attached to both lateral peritoneal wall with continous running suture. The lower margin is sutured to the parietal peritoneum of the posterior abdominal wall at the level of the aortic bifurcation. The pelvic reperitonealization was carried out in whole patients. RESULTS: In the group of radiotheraphy with abdominopelvic omentopexy, six patients showed signs of acute radiation enteritis, whereas no case of chronic radiation- induced enteropathy was observed. Other complications were postoperative ileus (three patients), urinary problems (four patients), radiation dermatitis (ten patients), and radiation-induced leukopenia (three patients). In the group of radiotheraphy without abdominopelvic omentopexy, 7 out of 38 patient developed symptom and sign of radiation- induced chronic complication. The chronic complication rate is significantly lower in the omentopexy group than in the non-omentopexy group (P=0.0089). CONCLUSIONS: Abdominopelvic omentopexy is effective for preventing the late sequela of radiation-induced enteritis.

Although adenosine (Ado) is being recently recognized as a potent inducer of apoptosis, molecular mechanism of apoptosis by Ado remains to be elucidated. In this study we observed that c-Myc was rapidly down-regulated in the apoptosis in human promyelocytic leukemia HL-60 cells treated with Ado. To establish the molecular and biochemical mechanisms of apoptosis, we tested the specific effects of several antagonists of Ado receptors or inhibitors of Ado transporter on the induction of apoptosis. Treatment of dipyridamole (DPD), an Ado transport inhibitor, effectively suppressed both c-Myc reduction and DNA fragmentation, suggesting that the induction of apoptosis and down-regulation of c-Myc is mediated by active Ado transporter. It was another evidence supporting the entrance of Ado into cells undergoing apoptosis that Ado cytotoxicity was potentiated by a addition of methylation cycle intermediates. These results suggest that the active Ado transporter-mediated Ado entrance into HL-60 cells leads to the induction of apoptosis through down-regulation of c-Myc.
