Early gastric cancer is defined carcinoma that is limited to the gastric mucosa and submucosa and that does not extend into the muscularis propria. The development and widespread use of upper gnstrointestinal endoscopy with biopsy and cytology have enhanced our ability to make early diagnosis of gastrie carcinoma. Gastric cancinoma is being diagnosed at an ealry stage aad the survival rates for these patients are significantly greater than those with advanced gastric carcinoma. These ealry lesion can be cured in over 90% of the cases. In fact, it is almost impossible to follow up cases of early gastric cancer without surgical treatment. We report a case developed advanced gastric carcinoma 34 months after initial endoseopic diagnosis of early gastric cancer. A, 48-year-old woman was diagnosed early gaatrie cancer on June 21, 1985 by endoscopy. Proper surgical intetvention was not carried out due to her liver cirrhosis. The follow-up endoscopic examination was done on March 16, 1988. The gastric cancer looked like an advanced stomach and extended to other site.

PURPOSE: Differential diagnosis of solitary pulmonary nodule with cavity includes lung abscess, tuberculoma, bronchogenic carcinoma, metastasis and trauma, etc. We analyzed the CT appearance of tubercuioma presenting as a solitary pulmonary nodule with cavity and describe the findings which suggest tuberculoma in the differential dignosis of soliary pulmonary nodule with cavity. MATERIALS AND METHODS: 25 patients with solitary pulmonary nodule(diameter less than 4 cm) without surrounding parenchymal consolidation on chest radiograph, who had a cavity within the nodule on CT, were included in our study. Density of the nodule, maximal wall thickness, the character of inner and outer wall margin, location of cavity within the nodule, location of the nodule, presence or absence of satellite lesions and calcification were analyzed. RESULTS: Solitary tuberculoma with cavity showed maximal wall thickness more than 15 mm in 40%(10/25) and 5-14 mm in 56%(14/25), eccentric cavitation in 84%(21/25) and concentric cavitation in 16%(4/25), spiculated outer wall margin in 56%(14/15) and Iobulated margin in 32%(8/25), smooth inner wall margin in 60%(15/25) and nodular margin in 40%(10/25). CT density of the cavity wall compared with the chest wall muscle was low in 84%(21/25) and isodense in 16%(4/25). Accompanying satellite lesions were seen in 84% (21/25) and calcification was visible in 28%(7/25). CONCLUSION: The CT findings of solitary tuberculoma with cavity are relative peripheral location, eccentric cavitation, finely spiculated outer wall margin, and mean maximal wall thickness of 13.2 mm, which are also the common features of malignant nodule. However, relative low density of the nodule compared to the chest wall muscle and surrounding satellite lesions can be additional clues favoring solitary tuberculoma with cavity on CT.

Surgical removal of impacted mandibular third molars frequently require tooth sectioning or bone removal. In this study, 361 mesioangular or horizontal impacted mandibular third molars are removed surgically by tooth section, the methods of tooth section are classified as 4 stages and 12 grades in the number of times and technics of crown or roots section and difficulties. Grades and their cases are followings: 1. occlusal crown first section(100, 28%) 2. distal crown first section(69, 19%) 3. occlusal crown second section(29, 8%) 4. distal crown second section(52, 14%) 5. occlusal crown first section and root section(10, 3%) 6. distal crown first section and root section(27, 7%) 7. occlusal crown third section(3, 1%) 8. distal crown third section(22, 6%) 9. occlusal crown second section and root section(13, 3%) 10. distal crown second section and root section(17, 5%) 11. occlusal crown third section and root section(2, 1%) 12. distal crown third section and root section(17, 5%)

BACKGROUND: To pass through the microcirculation, erythrocytes need to undergo considerable deformation. We performed an experiment to investigate the erythrocyte deformability in healthy adults and in patients with uncontrolled hypertension and controlled hypertension. METHODS: 5ml of whole blood is anticoagulated with 2mg ethylenediaminotetra-acetic acid(EDTA). 1ml graduated plastic syringe, without its plunger, is filled with anticoagulated whole blood to the 1ml mark, And the syringe is put into the assembled membrane holder. Under standard condition, whole blood is passed through a 5micro polycarbonate membrane filter under negative pressure of 20cm H2O. The studies are performed at roon temperature and within two hours of venipuncture. RESULTS: Erythrocyte deformability was observed in 91 normal healthy adults and 25 patients with uncontrolled hypertension and 18 patients with controlled hypertension. Following results were obtained. 1) In male control age group I, II, III, the erythrocyte deformability indices were 0.776+/-0.125, 0.792+/-0.189, and 0.714+/-0.172 respectively and in female the indices were 0.880+/-0.138, 0.865+/-0.182 and 0.796+/-0.170 accordingly. 2) THe RBC deformability indices in female control troup were significantly higher than the male group in statistics(p<0.05). 3) No significant differences were observed among each age group in control. 4) In patients with uncontrolled hypertension, each age group I, II and III, the erythrocyte deformability indices were 0.785+/-0.050, 0.775+/-0.122, and 0.692+/-0.133 respectively and in control group, the indices were 0.8365+/-0.140, 0.8252+/-0.186 and 0.7534+/-0.173 accordingly. And in patients with controlled hypertension, the indices were 0.820+/-0.00, 0.788+/-0.135 and 0.716+/-0.141 accordingly. 5) The erythrocyte deformability inddex in patients with uncontrolled hypertension were significantly lower than the control group(p<0.05), and no significant differences were observed among each age group between male and female in patients with uncontrolled hypertension. 6) There was no significant statistical difference of deformability indices between uncontrolled group and controlled group(p>0.05). CONCLUSION: This study reveals that the erythrocyte deformability in patients with essential hypertension is significantly lower than the healthy adults.
