To 48 adult patients general and spinal anethesia was administered for elective orthopedic (intra-thoracic and extremity) and abdominal(general and gynecological) operations. Radial artery was cannulated and postoperative change of PaO2 was observed for 7days. The results are as follows: 1) General anesthesia administered for operations on the legs results in a reduction of PaO₂ which is maximal immediately after discontinuation of anesthesia, gradually returns toward normal in a 3-hour period, and becomes normal on the first postoperative day. 2) General anesthesia administered for thoracomy and laparotomy is followed by the same early changes, which do not return toward normal in the first 3 hours. Reduciton of PaO₂ persists, and PaO₂ continue to deteriorate for several days, not completely returning to normal even 7days post-operatively. 3) When spinal anesthesia is administered for laparotomy, PaO₂ does not begin to fall untill several hours after the end of operation. The subsequent course follows as that in 2, above. 4) When spinal anesthesia is administered for operation on the legs, PaO₂ does not change significantly throughout the postoperative period. 5) Thus, it is concluded that late forms of postoperative hypoxemia is influenced primarily not by the method of anesthesia, but by site of operation.

The main purposes of this study were to survey and assess the current situation surrounding solid waste generation in school foodservices, to identify and evaluate the measures(reduction and recycling programs) taken by the foodservices for waste disposal, and to suggest appropriate reform measures to improve the current status, especially in terms of environmental preservation. Questionnaires on solid waste management practices were mailed to 206 school foodservice dietitians in the Kyungbuk region : a 64.0%(N = 130) response rate was obtained. While there are food waste and packaging waste generated from the foodservice operations, about a third(34.1%) of the foodservice operations were responsible for the disposal of both the food wastes and packaging wastes. About 90% of school foodservice managers were responsible for managing solid wastes. The primary recycling methods of leftovers generated from the school food service operations were livestock feed(76.0%). About 60.0% of school foodservice managers conducted the food waste reduction program. The performance by the foodservice managers in reducing the food waste was not satisfactory in several fields, such as developing environmentally friendly menus or abiding by the standard recipe, etc. In addition, the government assistance system was not properly working in the food service management. In conclusion, we should focus on increasing the performance in reducing the food waste by the foodservice managers, strengthening and facilitating the government assistance system for the food waste management and to develop education methods and education materials for food waste management.

The crossing laminar screw fixation might be the most recently developed approach among various fixation techniques for C2. The new construct has stability comparable to transarticular or transpedicular screw fixation without risk of vertebral artery injury. Quantitative anatomical studies about C2 vertebra suggest significant variation in the thickness of C2 lamina as well as cross sectional area of junction of lamina and spinous process. We present an elderly patient who underwent an occipito-cervical stabilization incorporating crossed C2 laminar screw fixation. We preoperatively recognized that she had low profiles of C2 lamina, and thus made a modification of trajectory for the inferiorly crossing screw. We introduce a simple modification of crossing C2 laminar screw technique to improve stability in patients with low laminar profiles.

In the present study, immunohistochemical detection of p53 oncoprotein was performed to determine whether the grade of differentiation and the histologic type of gastric adenocarcinoma, and the degree of atypia accompanied with adenoma can be related to p53 mutation. Paraffin sections of 22 gastric adenomas and 56 gastric adenocarcinomas were examined for the overexpression of p53 oncoprotein with the avidin-biotin peroxidase complex staining procedure. The obtained results were as follows; 1. All the 22 cases of adenomas and 16 cases of well differentated adenocarcinomas showed uniformly negative staining. 2.Seven of 18 cases of moderately differentiated adenocarcinomas(39%), and five of 30 cases of poorly differentiated adenocarcinomas(17%) exhibited p53 protein expression. 3. Three of 29 cases of diffuse type (10%) and 9 of 19 cases of intestinal type(47%) exhibited p53 protein expression. These results suggest that p53 mutation is important in carcinogenesis of the intestinal type of gastric adenocarcinoma, and there is no correlation between the differentiation of gastric adenocarcinoma and the degree of p53 oncoprotein overexpression.

OBJECTIVES: The purpose of this study was to assess the complications, duration of admission, cost effectiveness, radiologic stabilization of the anterior cervical bone fusion in the treatment of cervical disc disease with and without plating. MATERIALS AND METHODS: Fifty-two surgically treated patients for cervical disc disease were reviewed. Group I consisted of consecutive treated patients with iliac auto-bone graft without instrumentation after anterior cervical discectomy. Group II consisted of consecutive treated patients with iliac autologous-bone graft with CASPER cervical plate fixations. Radiologic fusion was decided when loss of end plate boundary between graft bone and vertebral body and immobile, maintenance of the disc space were evident on simple dynamic plain films. The patients were discharged after the stabilization of cervical motion by films was of tained. These groups were analysed multiple variably with Mann-Whitney U-test. RESULTS: Group I consisted of 18 patients, group II consisted of 34 patients. Mean age was 49.0+/-8.1 years, mean duration of admission was 17.27+/-10.51 days, mean costs for treatment was 1,970,000+/-475,000 won. In group I, mean age was 47.7(34-60) years, 16 patients had undergo on one-level operation, 2-patients had undergo on two-level operation, mean duration of admission was 28.7+/-10.4 days, mean costs for treatment was 2,194,473+/-561,639 won. The periods of stabilization was 6.6+/-3.36 weeks on radiologic study. Mean periods of out patient follow up was 16.8(6-64) weeks after discharge. Mean period of radiologic follow up was 17.3(4-6) weeks after surgical operation. In group II, mean age was 49.7(37-62) years and 18 patients one-level operation, 14-patients had undergo on two-level operation and 2-patients three-level operation. Mean duration of admission was 11.24+/-3.29 days, mean costs for treatment was 1,850,823+/-389,372 won. The periods of stabilization was 5.88+/-7.07 weeks on radiologic study. Mean period of out patients follow up was 16.7(4-60) weeks after discharge. Mean period of radiologic follow up was 12.4(3-52) weeks after surgical operation. The duration of admission showed statistical significance in Group II but other items showed no significant difference between two groups. CONCLUSIONS: The more economic, early life return and effective method of cervical disc disease in our series were evident in patients who had undergone, iliac bone graft and plate fixations after anterior discectomy.

PURPOSE: We evaluated the morphologic change of the hydroxyapatite(HA)-coated porous alumina as a new orbital implant when it was used in rabbit. METHODS: After evisceration of 18 eyes of 18 New Zealand white rabbits, we implanted 12 mm-diameter-sized HA-coated porous alumina with different pore sizes; 300, 500, and 800 micrometer, and then the implants were extracted back to evaluate their morphologic change according to different time interval; 2, 4, and 12 weeks. RESULTS: Fibrovascularization was noted at periphery of the implant 2 weeks after implantation in all of the three groups, and to the center of the implant 4 and 12 weeks after implantation. This fibrova-scularization was most predominant in 500 micrometerpore-sized group compared to the rest two groups. CONCLUSIONS: HA-coated porous alumina showed similar appearance of fibrovascularization with relatively more affordable price and easy manufacture, compared to the other porous implants.
