OBJECTIVE: In the development of squamous neoplasia of the uterine cervix, high risk HPV infection has been followed by CD44 variant expression and angiogenesis. The aim of this study is to evaluate the sequential changes and relatianship of CD44 variant expression, microvessel density (MVD), and VEGF expression in CIN III, microinvasive (MI) and invasive (CA) squamous cell carcinoma. METHODS: The materials were 17 cases of CIN III, 14 cases of MI and 15 cases of CA. In situ PCR for HPV 16/18 and immunohistochemical studies for CD44std, v6, v7/8, CD 31 for MVD, and VEGF were performed. RESULTS: CD44std expression was decreased in squarnous neoplasia compared to normal, and CD44v6 and v7/8 expressions were increased, however, there was no statistical significance. Accentuated staining of CD44v6 and v7/8 along the infiltrating borders was noted in 76.9% and 69.2% of MI and in 71.4% and 42.9% of CA, respectively. High MVD and VEGF 2+ expression were higher in the squamous neoplasia compared to narmal, however, there was no significant difference between the squamous neoplasia and no significant relationship between MVD and VEGF expression. The expression rates of CD44std and CD44v6 were higher in HPV 16/18 negative squamous neoplasia and that of CD44v7/8 was higher in HPV 16/18 pasitive squamous neoplasia, however, their differences were not significant. The incidences of high MVD and VEGF 2+ expression were higher in HPV 16/18 positive suqmaous neoplasia with no statistical significance. CONCLUSIONS: These results suggest that CD44 variants expression and angiogenesis are involved in the development of squamous neoplasia of the uterine cervix, however, HPV 16/18 might not be related to CD44 variant expression and angiogenesis.

This study was performed to assess the effect of one year's of meal service for home-staying urban elderly with low incole on their nutritional status. One hundred and eighty three subjects, who had already completed the first nutritional survey, were assigned to two group : meal served(served) and non-meal served(non-served). A meal containing approximately on half of the RDA for energy, protein, calcium and iron was served as lunch everyday to served group. After on year of meal service, follow-up-nutritional survey was done and changes of parameters were analyzed with paired t-test. Served female showed signficantly increased intake of riboflavin and calcium, while non-served female showed significantly decreased intake of calcium. Serum total protein, serum albumin and serum cholesterol were significantly increased in female regardless of meal service. Served remale was observed with significantly elevated LDL-cholesterol, whereas non-served female showed singnificantly lowered HDL-cholesterol. Significantly decreased serum iron, serum transferrin saturaion and significantly increased TIBC were observed for female regardless of meal service. But the proportion of anemic elderly according to Hb or serum iron was decreased more in served group. Female showed significantly increased serum zinc and copper regardless of meal service, whereas only served male showed significantly increased serum copper.

This study was carried out to investigate the development rates of human embryos co-cultured with cumulus cells to each blastocyst stage. Human zygotes were co-cultured on cumulus cell monolayer in YS medium supplemented with 20% hFF. On day 2, if patient had four or more 'good' embryos(regular blastomeres without fragmentation), embryos were further cultured for 72hrs. Blastocysts on day 5 were classified into early blastocyst (ErB), early expanding blastocyst (EEB), middle expanding Blastocyst (MEB), and expanded blastocyst (EdB) on the basis of their morphological aspects of trophectoderm cells and blastocoele. Subsequently, maximum 3 of best blastocysts were transferred in 486 cycles. The results in this study were as follows: Patients who had four or more 'good' embryos on day 2 were 498 persons, but patients whose embryos could not be transferred due to failure in development to the blastocyst stage on day 5 were 12 persons (2.4%). The development rate of embryos to the blastocyst stage was 58.2% (2,885/4,957) on day 5, and the rates that developed to the ErB, EEB, MEB, and EdB stage were 15.0% (743/4,957), 14.9% (739/4,957), 14.4% (714/4,957), and 13.9% (689/4,957), respectively. Total 1366 blastocysts were transferred in 486 cycles (mean number=2.81). The implantation rate and the ongoing implantation rate obtained by observing the number of G-sac and FHB were 29.9% (409/1,366) and 22.5% (308/1,366), respectively. The clinical pregnancy rate was 51.2% (249/486), and the ongoing pregnancy rate was 39.1% (190/486). Among women showing ongoing pregnancy, women with singleton were 50% (95/190), women with twin were 37.9% (72/190), and women with triplet were 12.1% (23/190). Although triplet pregnancy rate in this study was high such as 12.1%, because many blastocysts with high viability were produced in our co-culture system using cumulus cells on day 5, we really believe that a multiple pregnancy except twin should not occur by selecting good embryos for maximum two blastocyst transfer. These results demonstrate that autologous cumulus cells may be used for the production of blastocysts with high developmental competence, and the use of autologous cumulus cells to be collected easily, and to be treated conveniently at OPU must be an effective means for obtaining high implantation and pregnancy rate.

In case of submucosal tumor, adenoma and atypism, we can't frequently use the snare polypectomy for treatment of them. Adenoma and atypism are premalignant, so other therapeutic modalities are necessary for resection of them. We have perfortned endoscopic mueosectomy such as strip biopsy, and "O"ring ligation on various mucosal lesions of upper GI tract in 23 patients(11 men, l2 women) from June 1993 to December l994. Fourteen patients wbo had adenoma were followed up endoscopically for 6 months to 24 months(mean: 14 months). The results were as follows: 23 patients(27 lesions) were enrolled in this study. Mean age was 50.3(range 32-74 years). The method of mucosectomy was strip biopsy in 19 cases(21 lesions), and "O"ring ligation in 4 cases(6 lesions). The rate of complete resection was 88.9%. If adenomas were resected incompletely, we added a laser therapy. There was no recurrence except a case in which carcinoma was detected on the other site during follow-up. No serious compication occurred such as massive bleeding or perforation. Based on the above results, the endoscopic mucosectomy is considered to be a safe and effective modality in the treatment of the flat polyps of upper GI tract and could be used for prevention of gastric cancer.
