Soft tissue tumor is defined as a tumor occurring in voluntary muscles, fat, fibrous tissue, along with the vessels serving these tissue and peripheral nervous system. It is difficult to make a diagnosis by conventional microscopic observation because of their pleuripotentiality and similar growth characteristics. Although their morphological findings of tumors are similar to one another, their clinical courses, treatment and prognosis are different. So early, correct diagnosis and proper treatment are neccessary. The present study is aimed to evaluate a value of immunoperoxidase staining to make definite diagnosis of soft tissue tumors and its application to surgical pathology. The material consisted of 106 cases of fibrohistiocytic tumors and malignant soft tissue tumors which are morphologically similar to malignant fibrohistiocytic tumors for 5 years period lasting from 1980 to 1984 at the Department of Pathology, Yonsei University College of Medicine. After the classificationof fibrohistiocytic tumors by the Enzinger (1983), clinical finndings were reviewed and peroxidase antiperoxidase(PAP) method with alpha1-antichymotrypsin was done in 15 cases of all fibrohistiocytic tumors. Other soft tissue tumors which were difficult to differentiate from MFH by light microscopic observation were liposarcoma, rhabdomyosarcoma, fibrosarcoma and malignant schwannoma. These 21 cases of tumors including MFH were stained with PAP method for alpha1-antichymotrypsin, S-100 protein and myoglobin. Results obtained were as follows: 1) The cases on study consisted of 19 cases of malignant fibrous histiocytoma, 2 dermatofibrosarcoma protuberans, 45 fibrohistiocytic tumors and 11 other benign fibrohistiocytic tumors. 2) The male to female ratio was 1 : 1.8 in benign and intermediate group of fibrohistiocytic tumor, but 2.2 : 1 in malignant histiocytic tumor. 3) Most cases of benign fibrohistiocytic tumors were occurred in 4th and 5th decade of life. Intermediate and malignant fibrohistiocytic tumors were mostly found in late adult life and their mean age was 43.6 year. 4) The most common sites were trunk and both extrimities in benign fibrohistiocytic tumors(88.9%), but head, neck and lower extremities in MFH (78.9%). Two cases of dermatofibrosarcoma protuberans were occurred in turnk and upper extremity. 5) The PAP stain for alpha1-antichymotrypsin was done in 15 cases of 77 fibrohistiocytic tumors which included MFH, dermatofibrosarcoma protuberans, xanthoma, xanthofibroma, dermatofibroma showed variable degree of positivity to alpha1-antichymotrypsin. The positivity of alpha1-antichymotrypsin revealed no significant difference according to differentiation of the tumors, such as benign, intermediate and malignant. 6) The PAP stain for alpha1-antichymotrypsin revealed diffuse positivity in all cases of MFH and also in a case of malignant schwannoma, fibrosarcoma, liposarcoma and rhabdomyosarcoma, but myoglobin and S-100 protein were negative. In three cases of leiomyosarcoma, two of rhabdomyosarcoma and three of malignant schwannoma, alpha1-antichymotrypsin, S-100 protein and myoglobin were negative, although a few positive tumor cells were present, which may the considered as metatypci differentiation. Another possibility of this discordance was loss of antigenicity by improper procedure of paraffin embedding and poor differentiation of tumor cells. In summary, PAP method for specific tumor marker is important for proper diagnosis of soft tissue tumors, and application to surgical pathology.

Questionnaire survey was performed in order to set an adequate meal table for athletes taking their food preferences into consideration. The survey was conducted against 32 athletes of a professional soccer team. Statistical data analysis was performed utilizing SAS package program. The results of this study can be summarized as follows; 18.8% of the answerers were found out to consider their autotrophic nutritional status as above average, 75.0% considered theirs as up to the average and 6.2%, below average. Among answers to the question what they consider as the most critical factor in their staying healthy; sound sleep won the most votes followed by enough rest, tranquillity and balanced eating habit. Yet, 68.8% replied their meal sizes were not settled. And 46.9% thought nutritive supplement helpful and 96.9% of the answerers said a dietitian is required as their health manager. 62.5% of them preferred Korean cuisine. Chigye and Chongol were the most preferred menus(55.6%) and Namul (28.1%), Muchim(26.3%) and Cheok.cheon(23.9%) enjoyed relatively low preference.

This study was performed in order to measure consumed quantity of garlic and its content in each meal. Statistical data analysis was performed utilizing SAS package program. The results of this study can be summarized as followed ; 82% of foodservice surveyed has served garlic seasoned with soy sauce or vinegar etc. Kimchis was included in each meal in 98% of them and only 13.7% of them served Kimchis made by themselves. The Unit price of meal makes significant differences in the number of side dishes and the serving frequency of beverages and rice cakes. The content of garlic in meal were 2.6g in Soups, 2.9g in Stews, 1.9g in Namuls, 2.4g in Panbroiled foods, 3.0g in Hardboiled foods, 4.0g in Smothered dishes, 3.7g in Kimchis, respectively. Consumed garlic quantity makes significant differences by unit price of meal and consumption style of Kimchis(p<0.05).

This study was carried out to investigate the job characteristics and relationships between general charactristics and job satisfaction of the dietician in community health center. The subjects were 40 dieticians who responded to the questionnaire distributed at the annual education program in 1997. Statistival data analysis was completed using SAS packge program for frequencies, means, chi-square-test, ANOVA and Duncan's multiple range test. The results of this study acn be summarizd as follows. 45.0% of the dieticians were 26 to 30 years old, four-year-course university graduates were 75.0% and daily workers were 72.5% The level of hte job satisfaction of the dietician in community health center was the highes in the relationship with colleagues. The other parts of job satisfaction such as effects of nutrition counselling and education, value achievement as a dietician, general work and supervision by supervisors were above average, The general characteristics such as the age, the level of education, employment conditions, working hours per week and total length of service were significantly to all fields of job satisfaction except general work.

BACKGROUND: For gastric cancer, primary prevention by risk factor modification might have some important roles. However, previous studies having investigated the factors associated with stomach cancer reported various results. In addition, there were only a few studies based on Korean population. METHODS: A case control study was carried out on 106 cases matched for age and sex with 106 controls in a tertiary care hospital. In patients who were aged 75 years or less and had been newly diagnosed as adenocarcinoma of stomach between July 1996 and January 1997 were included into the case group. Information on baseline characteristics, health habits, dietary habits of study subjects was obtained through an interview using structured questionnaire. Conditional logistic regression analysis was used to evaluate the factors associated with stomach cancer. RESULTS: Salt preference was associated with significantly increased risk of stomach cancer (odds ratio[OR]=9.81, 95% confidence interval[CI]=2.28 42.2). Eating broiled food more than three times a week significantly increased the risk of stomach cancer (OR=3.33, 95% CI=1.16 9.55) compared to eating it less than once a week. Blood type, family history of stomach cancer, smoking, and alcohol consumption were not associated with stomach cancer. CONCLUSION: Salt preference and frequent eating of broiled food are the risk factors significantly associated with stomach cancer in this study subjects.

Great efforts have been expended to compensate for nerve gap in the repair of a peripheral nerve injury. And yet, this nerve gap presents a great problem in surgical management. End-to-end anastomosis is most frequently used for repair of peripheral nerves, but the main problem is tension at the suture site. The purpose of this experiment is to observe the relationship between the tension and the nerve healing, when stretching is applied to the suture site of the peripheral nerve trunk. We used 25 rabbits of both sexes divided into 5 groups according to the nerve gap and the period of immobilization for this study. Gross and histological examination were used to compare the results of end-to-end suture under a tension and suture without tension. We concluded that: 1. The best results were obtained when end-to-end suture was done without tension. 2. Direct suture under a tension produced the results quite inferior to that of the suture without tension. 3. Better results were obtained from the group of immobilization, at least, for 4 weeks among the tension group. 4. Immobilization period may be prolonged according to the degree of the tension affecting the suture site. 5. Tension at the suture site causes proliferation of connective tissue.
