1.A Study on the Tumor Angiogenesis and Expression of Cytokine and Growth Factors in the Prostatic Carcinoma.
Korean Journal of Pathology 1996;30(8):671-679
There is considerable experimental evidence to indicate that tumor growth is dependent on angiogenesis. However, we do not understand how the angiogenic activity is initiated by a given tumor. There is a clear distinction between a stage without neovascularization, which correlates with a paucity of metastases, and a stage in which increasing neovascularization correlates with a rising rate of metastasis. The authors therefore asked whether the extent of angiogenesis in human prostatic carcinoma is correlated with the tumor grades or some growth factors. To investigate how tumor angiogenesis correlates with tumor aggressiveness, the authors counted microvessels within the various grades of invasive prostatic carcinomas of 44 patients and the nodular hyperplasias of 10 patients. Highlighting of the vessels by immunohistochemical staining for factor VIII-related antigen and assessment of the tumor aggressiveness by the degree of expression of some growth factors(transforming growth factor-alpha, and beta, epidermal growth factor), tumor necrosis factor-alpha and tumor grading(Gleason's score) were done. As a result, both microvessel counts and the expression of growth factors and tumor necrosis factor correlated with tumor grades. In conclusion, the number of microvessels per 200 X fields in the areas of most intense neovascularization in a prostatic carcinoma may be a predictor of the patient's prognosis. Therefore, assessment of tumor angiogenesis may prove valuable in selecting patients with prostatic carcinoma, especially small needle biopsy, for aggressive therapy.

BACKGROUND: The purpose of this clinical study was to evaluate the Incentive Spirometry (IS) and Deep Breathing Exercises (DBE) to prevent postoperative pulmonary complications after abdominal surgery in patients over 60 years of age. METHODS: We prospectively randomized 90 patients into 1 of 3 groups: the control group (30 patients) received no respiratory treatment, the IS group (30 patients) was treated with incentive spirometry 4 times daily and DBE group (30 patients) carried out deep breathing exercises under supervision for 15 min 4 times daily. ABGA was taken at ward, PR (preop.room), RR (recovery room), POD1 day and POD2 day. Roentgenographic changes observed at 24 h. and 48 h. after surgery. Pulmonary complications were defined as the development of 3 or more of 6 new findings: cough, sputum, dyspnea, chest discomfort, temperature greater than 38oC, pulse rate more than 100 beats/min. RESULTS: PaO2 in the DBE group and IS group at PR were significantly increased than the values at ward, and the values of the PaO2 in the DBE group at RR and POD1 day, and those of IS group at PR and POD2 day were significant higher than those of the control group (p<0.05). The frequency of development of pulmonary complications (43.3% in the control group, 20% in the DBE group, 20% in the IS group) and roentgenographic changes were comparable in the 3 groups (26.7%, 16.7%, 20% respectively). The DBE group showed the different incidence of postoperative pulmonary complications between upper and lower abdominal surgery (upper: lower= 35.7: 6.3%). CONCLUSIONS: We concluded that DBE and IS were effective in preventing postoperative pulmonary complications after abdominal surgery and lower abdominal surgery causes lesser postoperative pulmonary complications than upper abdominal surgery.

The purpose of this study is to compared and analyze the shade changes(deltaE)about In-Ceram(R),IPS-Empress(R),OPC(R) by using of the spectrophotometer arising from initial status and before and after cementation of the resin cement mounted on the metal core. We used a couple of statistics such as 'One-Way ANOVA'and Multiple Range Test. We could be able to verify significantly what is being discussed here up to 95%. The results drawn from our research are as follows: 1. At the time of our experiments regarding the initial shapes of all-ceramic and mounting status of all-ceramic on the metal crown(deltaE1), and a comparison of mounting of all ceramic on the metal crown with all-ceramic cemented on the metal core(deltaE2), at the time of shade change of initial shapes and after we cemented on the metal core. (1) no significant difference among all-ceramics was found. (2) no particular difference was found regarding the In-Ceram(R) (3) a significant difference between the deltaE1 and deltaE2 regarding the IPSS-Empress(R) was found (P<0.05). (4) a significant difference between the deltaE1 and deltaE2 regarding the OPC? was found (P<0.05). 2. When we compared the shade changes (deltaE) resulted from before and after the cementation on each of the parts involved of some all-ceramic . we could be able to find shape change increase from incisal third, middle third, and cervical third in that order in In-Cream(R)(spinell), IPS Empress(R) and OPC(R) all. In addition , we could be able to find a siginificant difference between cervical third and incisal third, middle third. (P<0.05) From what we have just seen, we might conclude that there is a significant shade change difference before and after the cementation with respect to IPS-Empress(R)and OPC(R). In addition, we could also be able to find more shade change difference at the cervical third rather than incisal third and middle third depending on the parts involved.

The morbidity of spondylolisthesis tends to increase in accordance with the popularization of sports and increase of mean life span by the development of medicine. We had applied surgical treatment for 39 cases of spondylolisthesis during the period of 8 yrs. from Jan. 1976 to Dec. 1983 at Department of Orthopaedic Surgery, National Police Hospital, among them 35 cases were followed up for mean 27 months. Twenty eight cases with posterolateral spinal fusion were isthmic spondylolisthesis and seven cases with posterior spinal fusion and facetectomy were degenerative type. We analysed them with clinical aspects and surgical treatment for 35 cases. The results were as follows: 1. The most common clinical symptoms were low back pain (96.7%) and tenderness (93.5%). 2. The degree of slipping was Grade I by Meyerding's classification in all cases and mean 12.5% by Taillard method. 3. In the 7 cases of isthmic spondylolisthesis, the degree of slipping increased on standing lateral view. And in these cases the clinical symptoms were aggrevated at welking. 4. In the degenerative spondylolisthesis with posterior spinal fusion and facetectomy, we found mean 70% spontaneous correction of slipping commpared with preoperative. 5. In postoperative evaluation we gained 94.3% above good according to Gill's criteria and no pseudarthrosis.
