The tibial plateau fracture which involving articular surface of the proximsl tibia is very common in pedestrian injury of the traffic accident and sometimes results in significant disability in knee joint function. The authors analized 40 cases of the tibial plateau fracture treated in our depsrtment during the year 1980 through 1985. The results obtained are as follows : l. 15 cases were treated by conservative methods. 2. 25 cases were treted by operative methods. 3. 33 cases(82.5%) were “Acceptable” group according to Roberts criteria.

It would be naive to assume that any operative procedure is the solution to the problem of sacral pressure sore in the field of the orthopaedic surgery. The procedures outlined here involve the creation of compound myocutaneous flaps of the gluteus maximus muscle, skin, and the subcutaneous tissue. The myocutaneous flap us- ing the gluteus maximus muscle is a vascular flap instead of a random flap, with better blood supply for healing and advantage of an increased amount of cushion effect. We present an alternative method which will provide satisfactory and substantial soft tissue coverage in sscral pressure sores.

PURPOSE: For the purpose of using Re-188 as a therapeutic radionuclide, we performed the quality control of the W-188/Re-188 generation system. MATERIALS AND METHODS: Several quality control tests of the Re-188 eluate from generator were carried out of about 300 days. After elution of Re-188 with normal saline (20 ml), chromatogram and gamma-ray spectrum of Re-188 eluate were obtained. The presence of aluminum which was derived from the elumina bed of the generator was detected by using aluminum ion indicator kit. Re-188 eluate was allowed to decay for several days, and then W-188 breakthrough in the Re-188 eluate was measured by detecting gamma-ray at 227 keV and 290 keV. The pH and the pyrogenicity of the eluate were checked. The Re-188 eluate from the generator was 67.4+/-7.0% of W-188 during 270 days, and it was hightest at third day after previous elution. Radiochemical purity of Re-188 eluate obtained from chromatogram was higher than 99%. Gamma-ray spectrum of Re-188 eluate showed a peak at 155 keV. Aluminum ion and W-188 contamination were not detected. The pH of Re-188 eluate was 3 and the concentration yield was 85%. CONCLUSION: Our experiments and results on quality control tests of Re-188 eluate from W-188/Re-188 generator may be useful for setting W-188/Re-188 generator in hospitals.

The resistance of neoplastic cells to chemotherapeutic agents may develops by a variety mechanisms. One of these mechanisms seems to be the amplification or overexpression of the multidrug resistance(MDR) gene. The MDR phenotype is conferred by a 170kD membrane protein, P-glycoprotein. This protein acts as a drug efflux pump for a variety of structurally unrelated antineoplastic agents, especially hydrophobic natural products such as adriamycin and vincristine. In the present study, immunohistochemical stain for P-glycoprotein was performed in paraffin section of 41 specimens of transitional cell carcinoma of the bladder obtained prior to chemotherapy to investigate the usefulness of P-glycoprotein as a predictor of response to M-VAC ( methotrexate, vinblastine, adriamycin and cisplatin) chemotherapy. The overall clinical response rate to chemotherapy was 65.9%. The overall 3- year survival rate was 63%, with 80% in responder group( clinical complete and partial remission) and 36.3% non-responder group(minor response, stabilization and progression ) (P<0.05). In the responder group, 7.4% expressed strongly positive P-glycoprotein, 63% weakly positive and 29.6% negative. In the non-responder group, 28.6% expressed strongly positive P-glycoprotein, 64.3% weakly positive and 7.1% negative. The negative expression rate was high in responder group than non-responder, but this difference was not statistically significant. There was no correlation of expression of P-glycoprotein with either tumor stages or grades. In conclusion, these results suggest that tumors with negative expression of P-glycoprotein seem to have a better clinical response to chemotherapy, and further investigation of other mechanisms of cellular drug resistance should be required.

A silicone-covered modified Gianturco stent in patients with malignant esophageal stricture is an easy, safe, and effective palliative procedure, but reports of complications arising from stent placement in patients with this condition are numerous. There have been no reports of fracture of the modified Gianturco esophageal stent. We report a case of stent fracture in association with gastric migration of modified Gianturco esophageal stent in a patient with malignant esophageal stricture. It appears that the fracture was probably due to oxidation of the stent by gastric juice.
