Objectives : Stress induces alteration of gastrointestinal function in which interleukin (IL) and hypothalamo-pituitary-axis are involved. Depression again is associated with functional gastrointestinal disorders (FGID) and interleukins. The author attempted to look into the role of interleukins in the FGID also the association of depression and stress in this context. Methods : Entered were 20 patients with FGID, diagnosed by Rome IT criteria and 20 healthy controls. Depression was measured by Hamilton Rating Scale for Depression (HAM-D), and stress of the last one year by Schedule of Recent Experience (SRE). Serum levels of IL-$1\beta$, IL-2, IL-6 were measured by Enzyme-linked Immunosorbent Assay and serum cortisol by Fluorescence Polarization Immunoassay. The results were as follows : Results: 1) Serum levels of IL-$1\beta$, IL-2 were significantly lower in the patients with FGID than those in the controls, but level of IL-6 did not differ between two groups. 2) The patient group showed significantly higher level of serum cortisol as well as higher degrees of depression and stress. 3) Positive correlation was noted between depression and serum cortisol, and between depression and IL-2. A trend of negative correlation was seen between depression IL-$1\beta$. Positive correlation was noted between SRE and IL-6 and IL-6 and serum cortisol. Conclusions : It was concluded that FGID might be related to depression and stress. Changes of the interleukins might be involved with elevated cortisol level.

This experiment was conducted to identify the enzyme treatment time, calcium ion effect, enzyme concentration and leaf position for protoplast isolation. It was also performed to determine the adequate molarity on protoplasts, and to investigate the incubation time, pH, PEG concentration and DMSO effect for protoplast fusion. The results obtained were summarized as follows ; The optimal time of incubation in enzyme solution was 4 hours. And the protoplast releasing time was delayed by $CaCl_2{\cdot}2H_2O$ addition to the enzyme solution compared with no added one. The viability had kept up to above 95% until the 4 hours after digestion. The high viability of the protoplast was preserved more than 16 hours by adding $CaCl_2{\cdot}2H_2O$ to digestion solution. The enzyme concentration had no effect on protoplast yield in range from 1% to 5% and the first or second leaf from the top of the plant produced the highest protoplast yield among the leaf position tested. The purity of healthy protoplast was better in 0.4M and 0.5M sucrose than in others, and the percentage of protoplast aggregation was more 20% to 50% in PEG 6,000 compared with 4,000 and PEG 1,500. Even though the percentage of protoplast aggregation was less increased by 3% to 7% than without DMSO, its treatment was effective to induce binucleated protoplasts.

The serum levels of antioxidant materials (${\alpha}$-carotene, ${\beta}$-carotene, ${\beta}$-cryptoxanthin, lutein, lycopene, ${\alpha}$-tocopherol, ${\gamma}$-tocopherol, retinol) of the healthy Korean middle-aged adults (n = 373) were measured and their relationships with the serum lipids and anthropometric indices were analyzed. The serum levels of ${\beta}$-cryptoxanthin, ${\beta}$-carotene, lutein were higher than those of lycopene and ${\alpha}$-carotene. The levels of all measured carotenoids except lutein were significantly higher in females than in males, but retinol level was vice versa. There was a tendency of increase in serum levels of antioxidant vitamins with increasing age. The serum carotenoid levels had a positive correlation with serum cholesterol and a negative correlation with serum triglyceride. The serum levels of tocopherols or retinol showed a significantly positive relationship with blood cholesterol or triglyceride. In overall, anthropometric indices showed negative relations with serum carotenoids levels, but vice versa with serum tocopherol or retinol levels. Particularly, ${\beta}$-carotene and lutein levels showed a significantly negative relation with blood pressure in male subjects. The serum levels of ${\alpha}$-carotene, ${\beta}$-carotene and ${\beta}$-cryptoxanthin had significantly negative relations with body fat-related indices in female subjects. The results demonstrated that blood antioxidants levels differed by sex and age, and had significant relations with blood lipid levels and anthropometric indices. Therefore, the rationale and significance of the relationships need to be elucidated in the future study related to dietary intakes and life style.

Purpose - This study aimed to investigate the correlation between the social activity of the elderly and recognition of family cohesion of the elderly who are exposed to the current aging society. In addition, the study has delved into the method of family cohesion improvement through the differences between groups based on the mediator effect of how the results have effects on the elderly's self-control capabilities. Research design, data, and methodology - This study has targeted the elderly who are attending the elderly university among users in seven community centers located in Seoul and Gyeonggi-do area. The study has also conducted a survey by the format of a half-structured questionnaire. It is aiming to investigate the elderly's family cohesion with children and their self-control capability, and understand their satisfaction of social activity to help successful elderly life. The study has suggested the following as mentioned. First, the study analyzed that the perceptual factor of family cohesion with children would be deducted based on advanced researches. Second, the influencing relationship would be analyzed through the relational analysis between the elderly's family cohesion and social activity. Results - The family cohesion with children has a significant effect on psychological happiness and it showed the influencing relationship with improvement of the elderly's self-control capability. Therefore, creating fellowship through meaningful conversation with children would be needed. In addition, various programs and consultant service would be offered to build healthy relationship between aged parents and their children. Through this, the elderly will be able to have not only better relationships with their family, but also increased psychological health and well-being as well. Conclusions - It is needed that not only supporting policies for children who take care of aged parents but also that the elderly who need long-term care could meet their children whenever they want through increased numbers of sanatoriums operated by cities and countries. In addition, the nation would offer financial and administrative support continuously so that people receive the benefits from sanatoriums located in the locality of children's residence beyond the elderly's residence. Moreover, social infra would be established as well.

Various kinds of living circumstances are making population structure of Korean changed. That is, number of the children is decreased and that of the aged is increased. It is predicted that population of the children and the aged will be almost same until 2020. With above, as the expectation of the aged on healthy living might be increased, some special programs for the aged will be needed strongly. At this point, Korean aged population might be economically poor, comparing with other generation. In general, economic factor affects the subjective living-satisfaction and health status of them. Moreover, educational status, household shape and family tieing also affect their health status. According to the foreign articles, health status of the aged might be related to income, educational status, job, employed or/not, marital status, family structure, sex, and childhood condition. decrease of the income or unemployment could make the death rate of the aged higher. During childhood, discordance among the family might affect their health status after. IGUR is also important factor to affect the adulthood health. Positive life style of the aged would lessen their unequality of the health among them. Nutritional status of the Korean aged population might be indicated under the nutritional recommendation. It is affected by their income, education level, social class, and residing place. (Korean J Nutrition 33(1) : 86-101, 2000)

The purpose of this was to present the efficient directions of nutrition education for elementary school children. We examined the problems of eating habits. nutrition knowledge, and perception and expectations on nutrition education of elementary school children in school. This study was carried out using a self-administered questionnaire and subjects were 562 elementary school children in Gyeonggi Province. All data in this research was analyzed through SAS program, and the frequency$(\%)$ and the $mean{\pm}S.D.$ on each question were calculated. Data for each group was analyzed according to sex and the difference among the groups were treated for significance by using chi-square test and Student t-test. About $87.6\%$ of the children have a meal over three times a day, and $76.7\%$ answered that they ate at a certain time regularly everyday. Only $69.6\%$ of subjects said that they ate breakfast everyday, showing very high levels of skipping breakfast. The most common frequency of eating snacks was 'once a day' in both sexes(male $52.2\%$, female $48.6\%$). In the perception on the eating habits, $69.3\%$ of children recognized problems on dieting habits, such as unbalanced diet. irregular eating time, and overeating. The perceived and correct knowledge of nutrition were $99.5\%$ and $86.9\%$, respectively. Most of the children$(99.1\%)$ acknowledged that nutrition education need to be carried out in school. And children want to deeply deal with 'cooking', 'growth and nutrition', 'good eating habits', 'nutrition and disease', These results indicated that elementary school children tended to have undesirable eating behaviors, but the rate of children who recognize the importance and the needs of nutrition education in school was high. Therefore, their parents and teachers need to perform continuous education through a curriculum and life instruction so that students have healthy habits by considering what the problems of nutrition habits are, as the elementary students considerably recognize problems of their own dietary habits and needs of nutrition education.

The main focus of this study was set to help college students in Kangwon province to improve and correct dietary habits and to maintain healthy life. The nutritional status and food preference of college students were examined from May to July, 1999. The collection of the research data has been made on the basis of questionnaries for 184 college students residing in Kangwon province. Statistical analysis of the data was performed using SAS package program for descriptive frequency and statistical significance. The meal skipping ratio of the subjects were 2% and for the reasons of meal skipping 45% responded "lack of time". As for main dishes, cooked rice turned out to be the most preferred by the subjects and the second and third favored by female students were bread and noodle respectively. Most preferred side-dishes were meat soup, kimchi, laver Kui,squid Bockeum, fried squid, beef Chon, squid Chorim, soy Namul, Dubuk Changachi and squid Muchim. Less preferred side-dishes include radish soup, white kimchi, mugwort fry, liver Bockeum, liver sheon and egg plant Kui. No one-plate food was disliked by the subjects. Male liked Manndukuk and female liked cuttle fish rice. The intakes of nutrient except for energy, iron and calcium for female students were the same or above the Recommended Dietary Allowances (RDA) for Koreans.

Fabry disease (FD) is an X-linked lysosomal storage disorder caused by an ${\alpha}$-galactosidase A (GLA, MIM 300644) enzyme deficiency due to pathogenic variants in the ${\alpha}$-galactosidase A gene (GLA). The disease leads to accumulation of globotriaosylceramide (Gb3) and related glycophospholipids affecting nearly all major organ systems, with the primary sites damaged by Gb3 including renal glomeruli, myocardium, neurons of the dorsal ganglion and autonomic nervous system, and vascular endothelial and smooth muscle. Progressive deposition in these organ systems present with various clinical manifestations including acroparesthesia, renal failure and heart failure. Here, we report a Chinese male diagnosed with Fabry disease in his late $4^{th}$ decades showing improvement of acroparesthesia during enzyme replacement therapy (ERT). A 48-year-old Chinese man who presented with chronic recurrent severe burning pain in his fingers and toes since the age of 10, with worse involvement of the former visited to our clinic for further evaluation. His medical history included a transient ischemic attack aged 40 and diagnosed with stage 4-5 chronic kidney disease aged 47. In the family history, the patient's brother was found to be have Fabry disease 1 month before his visit. Except for his brother, all other members of the family are healthy. Based on his medical history and family history, he was strongly suspicious for Fabry disease. He was found to have a galactose-alpha-1,3-galactose level 4.96 (Reference range, 42.5-67.9) suggestive of Fabry disease. The followed sequencing of GLA coding region in our patient revealed hemizyosity for the mutation c.988C>T (Q330X) in Exon 7. Since ERT start, he showed significant improvement in his symptoms of burning sensation of fingers and toes. On the contrary, due to deteriorating kidney function even with ERT, he is considered for kidney transplantation. Despite of diagnostic delay until late 4th decades, ERT showed a potential improvement of acroparesthesia in our patient. However, late start of ERT can lead to poor outcome in multiorgan function. Therefore, early diagnosis with high index of suspicion followed by continuous ERT with regular monitoring have an impact on quality of life in Fabry disease.

This study was conducted to identify the factors related to the blood pressure in school children. The study subjects were 144 boys and 140 girls aged 10 years old, 4th grade student of one elementary school in Taegu City. Blood pressure and 18 variables for 284 school children were measured in May 1992. A weight-for-height index, R$\ddot{o}$hrer index(weight/$height^3$) was calculated for each individual as a measure of obesity. Body fat percent, fat weight, and lean body mass were measured by impedance fat meter(Model SIF-891). Serum total cholesterol, high-density lipoprotein, triglyceride, uric acid, total protein, and electrolyte were measured by automated clinical chemistry analyzer(Hitachi 4020). Low-density lipoprotein and atherogenic index were calculated by the equation. The variables assessed were sex, systolic blood pressure, diastolic blood pressure. R$\ddot{o}$hrer index, body fat percent, body fat weight, lean body mass, total cholesterol, high-density lipoprotein, low-density lipoprotein, uric acid, total protein, serum electrolyte and blood glucose. The mean systolic and diastolic blood pressures for boys were 104.1mmHg and 66.6mmHg and those for girls were 102.9mmHg and 67.5mmHg. Systolic blood pressure of boys was positively correlated with height, weight, R$\ddot{o}$hrer index, fat weight, lean body mass, and triglyceride. Systolic blood pressure of girls was positively correlated with height, weight, lean body mass, and uric acid. Diastolic blood pressure of boys was positively correlated with weight. R$\ddot{o}$hrer index, and lean body mass. Diastolic blood pressure of girls was positively correlated with height, weight, fat weight, and lean body mass and negatively with total serum protein. In multiple regression analysis for the systolic blood pressure, the significant independent variables were R$\ddot{o}$hrer index and serum sodium in boys, and serum uric acid, fat percent, and R$\ddot{o}$hrer index in girls. In multiple regression analysis of the diastolic blood pressure, the significant independent variables were R$\ddot{o}$hrer index in boys and total serum protein in girls. This study indicated that important factors influencing blood pressure in school children were R$\ddot{o}$hrer index, fat percent, serum sodium, uric acid, and total protein. R$\ddot{o}$hrer index was most important among these. It is recommended to enforce the nutritional education for diet control of obesity to prevent hypertention in children and to adopt healthy life-styles that promote good health and prevent development of cardiovascular risk factors.

Purpose: As basic information of antioxidant treatments for the patient with paraquat intoxication, in human peripheral lymphocytes, the cytotoxicity of paraquat was measured, and to evaluate the antioxidant effect of vitamin C and deferoxamine against this cytotoxicity, malondialdehyde (MDA), superoxide dismutase (SOD) activity and total antioxidant status (TAS) were measured. Methods: From 10 healthy adults, after obtaining a consent, 20ml peripheral blood was collected. Experimental groups were divided to (1) control group, the group treated with an identical amount of saline, (2) P group: the group treated with paraquat only, (3) PV group: the group treated with paraquat followed by vitamin C 30 minutes later, (4) PD group: the group treated with paraquat followed by deferoxamine 30 minutes later, (5) PVD group: the group treated with paraquat followed by vitamin C 30 minutes later and subsequently deferoxamine one hour later, and (6) PDV group: the group treated with paraquat followed by deferoxamine 30 minutes later and subsequently vitamin C 1 hour later, and thus to total 6 groups. In each group, 10 samples of peripheral blood was assigned and $100{\mu}M\;paraquat,\;100{\mu}M$ vitamin C, and $100{\mu}M$ deferoxamine were used as reagent. Lymphocytes were isolated, cultured, and cytotoxicity was measured by the Microculture Tetrazolium method (MTT assay), MDA and SOD activity, and TAS concentration were measured. Results: In regard to the cytotoxicity measured in each group, their cytotoxicity was decreased in the group treated with antioxidants, in comparison with the group treated with paraquat only. In the cases that the order of the treatment of these two antioxidants was altered, viability in the PDV group $(1.077{\pm}0.121)$ was increased more that the PVD group $(0.888{\pm}0.152)$ statistically significantly (p=0.018). Concerning the amount of MDA, in comparison with the P group $(6.78{\pm}0.93{\mu}mol/L)$, after the treatment of each antioxidant, the concentration of MDA was decreased statistically significantly (p<0.05). In the group treated with two antioxidants together, in comparison with the group treated only with one antioxidant, the amount of MDA was increased statistically significantly $(PV:\;3.96{\pm}0.98{\mu}mol/L,\;PD:\;4.92{\pm}1.50{\mu}mol/L,\;PVD:\;3.22{\pm}0.83{\mu}mol/L,\;and\;PDV:\;3.42{\pm}0.95{\mu}mol/L,\;p=0.007)$. The concentration of SOD measured in the blood in each group after the administration of paraquat, in comparison with the control group, a pattern of the elevation of SOD activity and subsequent decrease was detected, however, it was not statistically significant. In the comparison of the groups treated with antioxidants, in comparison with the P group $(1419.9{\pm}265.9{\mu}mol/L)$, SOD activity was decreased statistically significantly in only the PDV group $(1176.4{\pm}238.9{\mu}mol/L)$ (p=0.017). In regard to TAS measured in each group, in comparison with the P group $(0.87{\pm}0.05{\mu}mol/L)$, in all groups treated with the antioxidants, the PV group was $1.00{\pm}0.03{\mu}mol/L$ (p=0.005), the PD group was $9.01{\pm}0.24{\mu}mol/L$ was $4.64{\pm}3.98{\mu}mol/L$ (P=0.005), and the PDV group was $9.41{\pm}0.27{\mu}mol/La$ (p=0.005), and thus total antioxidant activity was increased statistically significantly In a multiple comparison test, the PDV group showed the highest total antioxidant activity (p<0.0001). Conclusion: The result of the assessment of the antioxidant effect of vitamin C and deferoxamine on paraquat-induced cytotoxicity showed that in regard to cytotoxicity, SOD activity and TAS measurement, the best result was observed in the PDV group. Therefore, it was found that vitamin C and deferoxamine were effective antioxidants for the paraquat-induced cytotoxicity, and it suggests that the administration of deferoxamine followed by vitamin C may improve their antioxidant effect more.
