한강 고수부지 및 지천인 안양천, 탄천, 중랑천변의 경작지에서 채집된 36종 285건의 농작물에 대한 Pb, Cr, Cd, Fe, Zn, Mn, Cu. Hg의 농도를 측정하고 그 결과를 채집 시기, 채집 지역 및 작물별로 비교, 분석한 결과, 작물 중의 중금속 함량은 평균치를 기준으로 볼 때 Fe(34.592 ppm)>Mn(11.071 ppm)>Zn(8.853 ppm)>Cu(1.795 ppm)>Cr(0.237 ppm)>Pb(0.100 ppm)>Cd(0.011 ppm)>Hg(0.003 ppm) 순으로 곡류 및 두류에서는 Zn의 함량이 Mn보다 높고, 채소류와 과실류에서는 Mn의 함량이 Zn보다 높은 양상을 나타냈다. 또한 각 지역에서 채취한 작물의 미량금속 함량의 경우 Fe은 0.004∼203.083 ppm, Cu은 0.017∼22.727 ppm. Mn은 0.000∼74.373 ppm. Zn은 0.080∼37.166 ppm으로 비교적 고농도로 존재하고 있는 반면 유해중금속류인 Pb은 0.000∼0.654 ppm, Cd은 0.000∼0.270 ppm, Cr은 0.000∼l.229 ppm, Hg은 0.000∼0.037 ppm으로 비교적 미량으로 존재함을 알수 있었다. 대상 농작물을 잎, 줄기, 뿌리, 열매로 분류하여 미량금속 함량을 분석한 결과, 분석 대상 금속의 농도가 잎>줄기>뿌리>열매의 순으로 나타났다. 무등의 뿌리 작물에 있어서 Pb은 잎(0.055 ppm))뿌리(0.035 ppm), Cr은 잎(0.118 ppm))뿌리(0.031 ppm), Cd은 잎(0.004 ppm)1뿌리(0.001 ppm), Hg은 잎(0.004 ppm))뿌리(0.001 ppm)으로 뿌리보다 잎에 많은 것으로 나타났는데 이러한 결과로 보아 뿌리는 금속 이온이 흡수되는 기관일 뿐 축적은 잎에 비해 상대적으로 적게 됨을 알 수 있었다. This study was conducted to determine the content of trace metals in crops cultivated in Han-riverside, Anyang stream, Tan stream, and Jungryang stream. Trace metals (Pb, Cr, Cd, Fe, Zn, Cu, Hg) were detected in 36 crops, 285 samples by Atomic Absorption Spectrophotometer and Mercury Analyzer. The average concentration of trace metals in crop samples was in the order of Fe (34.592 ppm)>Mn (11.071 ppm)$\geq$Zn(8.853 ppm)>Cu(1.795 ppm)>Cr(0.237 ppm)>Pb(0.100 ppm)>Cd(0.011 ppm)>Hg(0.003 ppm). In crop samples, the contents of Fe, Cu, Mn, and Zn, which ranges were 0.004-203.083 ppm, 0.017~22.727 ppm, 0.000~74.373 ppm, 0.080~37.166 ppm, respectively, were relatively higher than those of Pb, Cd, Cr, and Hg, which ranges were 0.000~0.654 ppm, 0.000~0.270 ppm, 0.000~l.229 ppm, 0.000~0.037 ppm, respectively. The concentration of trace metals in crop samples was in the order of leafy vegetables > stem vegetables > root vegetables > fruity vegetables. In the root vegetables, such as radish, the content of Pb was leaf(0.055 ppm)>root(0.035 ppm), that of Cr, leaf (0.118 ppm)>root(0.031 ppm), that of Cd, leaf(0.004 ppm)>root(0.001 ppm), that of Hg, leaf(0.004 ppm)>root(0.001 ppm). As the results, it could be thought that root is the organ which doesn't accumulate the heavy metal ions, but absorb them.

A promising application of Lactococcus lactis is its use as live vehicles for production and delivery of heterologous proteins of vaccines and therapeutic substances. Because L. lactis has GRAS ("generally regarded as safe") status, use tested whether L. lactis could function as the carrier of the L1 protein of human papillomavirus (HPV) type 16. The RNA level expression of L1 gene was detected in L. Laois. The L1 protein was expressed in L. luctis with LI gene. The growth of strains L. lactis with an empty plasmid (pAMJ328) and L. lactis with L1-encoding plasmid (pAMJ328-L1) was slightly decreased in comparison with the growth of strains L. lactis (wild type). However, all the three strains of L lactis maintained the ability to ferment sugars primarily into lactic acid, indicating that L1 protein did not affect the biochemical property of L.. lactis. These results suggest that L. lactis. capable of carrying LI protein, might he further developed as a biocompatible oral protein delivery system.

Backgrounds and Objectives: Vascular dementia is a group of dementing disoders arising from various stroke syndrome. Among these. subcortical ischemic vascular dementia (SIVD) is regarded as a relatively distinct clinical entity. However, MRI patterns of SIVD are not homogenous. In some patients, lacunes are dominant, and in others, subcortical white matter changes are. This study was designed to compare risk factor profiles between SIVD with and without multiple lacunes. Methods: We divided 47 subjects (22 males, mean age. 68 years) recruited from VADAPET (Multicenter Trial For Evaluation Of The Changes In the PET Images Of Subcortical Vascular Dementia Patient) study into two groups one with more than 5 lacunes in deep gray matter (lacune group) and the other with 5 or less(non-lacune group) Clinical characteristics and laboratory findings of two groups were compared. Results: Nineteen of 47 patients (40%) belonged to the lacune group. The lacune and non-lacune groups d d not differ in the following variables: age, hypertension, diabetes mellitus, hyperlipidemia heart disease, history of stroke or TIA, history of trauma or major surgery, family history of hypertension stroke, or dementia, age at diagnosis of dementia, body mass index, white blood cell count, ESR, CRP, fibrinogen, hemoglobin A1C, total cholesterol. LDL cholesterol creatinine, proteinuria, glucosuria, and microhematuria. However, male sex, smoking alcohol. hemoglobin, and HDL cholesterol were possibly associated more with lacune group SIVD than with non-lacune group (p<0 1) Multivariate analyses revealed that smoking, hemoglobin, and HDL cholesterol were independent predictors of SIVD with multiple lacunes Conclusion: Our study suggests that SIVD with multiple lacunes may be significantly different in smoking habits hemoglobin, and HDL cholesterol from SIVD without multiple lacunes.

Mental illness such as schizophrenia, bipolar disorder and depression have shown high prevalence of obesity. According to the previous studies, nutrition education has therapeutic effects on patients, however mentally ill patients rarely have opportunities of long term nutrition education. In this study, nutrition education based on the social cognitive theory was conducted. Patients with mental illness received education program once a month during 18 months in a day hospital. Fifteen patients were included and divided into two groups according to the attendance rate. Results showed that the group attended the education more than 10 times showed weight loss, while the group less than 10 times showed weight gain. Five long-term hospitalized patients gained weight during one year prior to the nutrition education, but showed weight loss during one year with the nutrition education. Regardless of the number of attendance, the group of BMI≥30kg/m2 showed weight loss. Although this study has several limitations and did not obtain a statistically significant results, it confirmed the necessity of providing clinical nutrition services including nutrition education for mentally ill patients.

The propose of this study is to find out how well the middle school students are practicing the health Promotion behaviors and the factors relating their health promotion bahavior. Questionnaire survey on 922 middle school students attending 6 middle schools (three middle schools for each sex) located in Taegu City from the 7th through 19th of Feb. 2000 were conducted. The following were as follows; 1.The perceived health status is higher in male students than in female students(p<0.01). And the ratio of the students' feeling that they are healthy becomes also high in proportion to their economic status, and their mothers' educational level, and their parents' interest in health(p<0.01). The perceived importance of health is high in proportion to the student's economic status, and their parent's interest in health. 2.In case of the Health Locus of Control in Personality, the students with both parents have higher trend of inner control than the students with single mother or single father. The perceived self efficacy is significantly higher in male students than in female students(p<0.01). And it becomes significantly high in proportion to the students' economic status and their parents' educational level and interest in health(p<0.01). It is also higher in the students who had no diseases. 3.In case of the perceived benefit of the health promotion behavior, the ratio of the students responding that it is high is higher in male students than in female students(p<0.01). It also becomes high in proportion to the students' economic status, and their parent's educational level and interest in health(p<0.01). The barriers of the health promotion behavior was found to have no variables that are related to itself. 4.According to the data from Multiple Regression of Analysis which has the health promotion behavior practice as a subordinate variable, in male students' case the degree of health promotion behavior practice becomes high in promotion to their parents' interest in health, and the perceived health status. Their degree of health promotion behavior practice is also in proportion to their perceived self efficacy and the perceived benefit of the health promotion behavior practice. But in case of the barriers of the health promotion behavior practice, the result is the opposite. As to the female students, their health behavior practice becomes high in proportion to their parents' interest in health. It also becomes high in proportion to the perceived health status, the understanding of the importance of the health, the perceived self efficacy and the perceived benefit of the health promotion behavior. But in case of the barriers of the health promotion behavior, it was the same as the male students' case.
