Detailed mechanism of uterine cervical cancer progression still remains unclear. Altered programmed cell death (apoptosis) and cellular proliferation are associated with the development of neoplasia. The authors investigated the expressions of bcl-2, which inhibit apoptosis, and caspase-3, which is involved in the induction of apoptosis and has been considered to be correlated with apoptosis, and proliferating activity according to the degree of malignancy in the squamous neoplasia of the uterine cervix. Correlation between bcl-2 and caspase-3 expression and proliferating activity was done. The materials were low grade squamous intraepithelial lesions (LSIL, n=15), high-grade squamous intraepithelial lesions (HSIL, n=15), microinvasive squamous cell carcinoma (n=15), and squamous cell carcinoma (n=15). Immunohistochemical stainings for bcl-2, caspase-3, and MIB-1 were done. bcl-2 and MIB-1 expressions were progressively increased in accordance with the increasing degree of malignancy, but caspase-3 immunoreactivity was higher in LSIL than invasive cancers. There was an inverse relationship between bcl-2 and caspase-3 expression, but the difference did not reach statistical significance. No significant correlation between MIB-1, bcl-2, and caspase-3 expressions was observed. These results suggest that an inhibition of apoptosis and the augmentation of proliferating activity of tumor cells might be separately involved in the development of the cervical squamous neoplasia.

We investigated elementary school students' knowledge, behavior, experience and preference of education method related to food safety in order to provide basic information for food safety educational program. A survey study was conducted with 569, fourth and sixth grade students, from two schools in Seoul and Ulsan. Students were asked thirty-two questions regarding food safety knowledge, behavior and experiences as well as their attitude to food safety class and preference for teaching method. The data was analyzed for the frequency analysis, t-test, chi-square test, one-way ANOVA and Pearson correlation using the SPSS/Windows. Results indicated that 91.9 percent of the respondents did not know what unsanitary food is. 67 percent of the respondents did not know the proper method of hand washing. Although the students' level of knowledge and behavior associated with food safety was low, there was meaningful correlation(r =.184, p<.01) between knowledge and behavior. Surprisingly, students in higher grade did not demonstrate an exceeding food safety knowledge and behavior. More than 50 percent of the subjects did not have food safety education either at home or school. 60 percent of the respondents interested in food safety and the majority recognized that a food safety education is needed. Students want to learn about unsanitary food(34.1%), foodborne illness(29.7%), food selection and storage method(21.3%), and personal hygiene(11.2%) through game, role play, and practice in real situation. These results suggest that development of food safety education program is needed through the elementary school year and the education program must include fun activities in which students can participate.

PURPOSE: This study aimed to assess the risk of developing cardiovascular disease (CVD) and to evaluate the effects of intervention for CVD prevention in construction workers. METHODS: A total of 497 workers participated the health status survey and finally 90 workers were analyzed for evaluation of the intervention with the one-group pretest-posttest design. The data were collected from the questionnaires and health examinations in the healthcare service for road constructor's CVD prevention as secondary analysis. The intervention of the healthcare was composed of CVD prevention education for all workers and face to face counselling for the high risk group of CVD risk during 6 months in workplace. Data were analyzed with descriptive statistics, χ² test, Wilcoxon signed rank test, and paired t-test. RESULTS: The moderate and high risk groups of CVD were 9.7% and 0.8%. After the intervention, the physical activity (MET-min/week) significantly increased (Z=-5.46, p<.001). But, there were no significant differences in blood pressure, fasting glucose, body mass index, and CVD risk appraisals between pre and post intervention. CONCLUSION: The findings imply that it is necessary to develop the health promotion program for construction workers which fully reflects the characteristics of individuals and the organization.

Granulocytic sarcoma.(chloroma) is a localized tumor mass composed of immature cells of the granulocytic series infiltrating an extramedullary site. The tumor may involve anywhere in the body, especially orbit, bone, epidural space and lymph node, but there is no case involved the esophagus. In a 34-year-old male presented with sudden anset of dysphagia, esophagoscopic examination revealed concentric narrowing of the esophageal lumen wirith alight granular mucosa in the midesophagus, which hiatologically proved to b a granulocytic sarcoma. Peripheral blood and bone marrow aspiration smears showed blastic crisis of chronic myelocytic leukemia. After the systemic chemotherapy, dysphagia and mid-esophageal luminal narrowing disappeared completely.

Advance in fiberoptic endoscopy have improved diagnostic capabilities and management in patients with gastric polyps and increased experience with endoscopic polypectomy offers the most simple and safe method in removal of gastric polyps. Sixty six endoscopic gastric polypectomies was performed in 59 patients who visited Chonnam National University Hospital from 1980 to 1989 The results obtained were as follows. 1) The most patients were in the seventh decade followed by fifth, fourth decade. The ratio of male to female was 1: 1.95. 2) The common clinical symptoms with which patients presented were epigastric discomfort (54. 2%), epigastric pain (44.1%), indigestion (16.9%), nausea and vomiting (13.6%) and hematemesis (3.4%). The associated diseases of gastric polyp were chronic superficial gastritis (28.8%), chronic atrophic gastritis (13.6%), benign gastric ulcer, gastric caecer, cancer of ampulla of Vater. 3) The number of patients with single gastric polyp wa 47 (79.7%), and that of multiple gastric polyps was 12 (20.3%). The most common location of gastric polyps was gastric antrum (66.6%) follawed by gastric body (27.3%) and gastric fundus (6.1%). 4) The removed polyps were mostly 1.0 cm to 2.0 cm in size and in the gross findings by Yamadas classification, type IV (48.5%) was most common. 5) Histogical examinations revealed that 49.6% of remoyed polyps were hyperplastic polys and 18. 7% of those were adenomatous polyps. Only one case of adenomatous polyp had contaied focally malignant change of mucosa. 6) Almost all cases were in the absenee of significant complications, but three patients showed bleeding at the site of polypectomy, which controlled by conservative means.

The sonographic features of 23 lymphangiomas (19 pediatric patients) were compared with the pathologic findings. Nineteen lymphangiomas appesred as unicameral (n=2) and multiloculated (n=7) cystic masses. Remaining lesions were inhomogeneously echogenic mass with small cystic portions (n=3) and a mixed pattern (n=1). Fourteen of the multiloculated tumors had thin septa and 6 had solid echogenic foci. The fluid within the majority of the cyst was anechoic in 8 cases and echogenic in 11 cases. Correlation of the sonographic features with the pathologic findings demonstrated that the cystic spaces corresponded to the dilated lymphatic spaces lined with endothelium, separated by septa. Echogenic fluid represented hemorrhage. The echogenic component corres ponded to clusters of very smaller dilated lymphatic channels, thick fibro-fatty septa, or blood clot. The author's experience suggests that the most characteristic sonographic appearance of lymphangioma is a multiloculated cysti mass with thin septa, reflecting the preponderance of fluid-filled spaces. An atypical appearance usually reflects the presence of blood or dominancy of cavernous type. The information obtained with US imaging can help in providing a preoperative diagnosis and in planning surgical resection.

The halophilic bacterium, Vibrio vulnificus, causes acute fulminating wound infections and septicemia in human. Especially the septicemia shows high mortality above 50%. In Korea, septicemia by V. vulnificus was reported at westem and southern coast in every year. Here, we try to isolate this V. vulnipcus at Kyoung-nam area and coast of Pusan during 1996. Purposed sites were Dadaepo, Songjung, Chungsapo and Mipo of Pusan and Kijang, Ilkuang, Juksoung, Dongam, Waljun and Chilam of southern sea. Total 40 strains of V. vulnipcus were isolated from sea samples. Biochemical characteristics of isolated V. vulnificus were almost same with reference strain V. vulnificus ATCC 27562 on Farmer's tests and on API 20E kit test. V. vulnificus isolates in 1996, fermented cellobiose and salicin but arabinose. and had resistance to 7% sodium chloride.
