To examine the relationship between the causal infection of gastric cancer and lifestyle and nutritional status, we surveyed 183 persons, 102 female and 81 male, aged 40 years and over from August to October, 1996, in Chunchon area, Kang Won Do, Korea. For this purpose, we investigated Helicobacter pylori infection in the agricultural Korean adult and identified the effect of sex, age, smoking, alcohol consumption, economic status, occupation and lifestyle. Helicobacter pylori immunoglobulin G(IgG). Helicobacter pylori infection was present in 64.5% of total subjects, and 63.7% of female, 65.4% of male and its prevalence was increased with age, smoking, low education level, low monthly income, high childbirth. Some nutrients intakes were significantly difference between Helicobacter pylori infection positive(+) group and those negative(-) group. The negative Helicobacter pylori infection group were much more intaked energy, total protein, total fat(p<0.05), animal fat(p<0.05), Iron(p<0.001), vitamin A(p<0.01), vitamin C(p<0.05) than Helicobacter pylori positive infection group. But the calcium intakes were lower than positive(+) group.

The purpose of this study was to evaluate the effect of short-term nutrition education camp on food and nutrient intakes of obese children. The subjects of the study were 30 obese children in Gumi city who have obesity index over $130\%$. The food consumption of the subjects was surveyed for three days before the camp, for eleven days during the first camp and for three days after the second camp, by food record method. The mean intakes of energy and carbohydrates in obese children were significantly decreased during and after the nutrition education camp, and that of vitamin C was significantly increased after the camp. The mean daily total food intake of the subjects was gradually decreased from 1646.4g before the camp to 1438.6g during the camp and 1412.66g after the camp. Energy and fat intake ratios from grains and milks were significantly decreased after the camp compared with that before the camp, and the energy intake ratio from grains, milks and eggs was significantly low during the camp. The protein intake ratios from grains, potatoes, vegetables and fishes were significantly increased after the camp. The calcium intake ratios from potatoes and milks were significantly increased during and after the camp, and the ratio from eggs was significantly decreased after the camp. The iron intake ratios from potatoes and fishes were significantly increased during and after the camp, and the ratio from grains was significantly low during the camp. The results of the study demonstrated that the short-term nutrition education program positively affected the overall food consumption and nutrients intakes of obese children.

Precise and correct assessment of nutrient intake using appropriate dietary intake method is necessary to improve the nutritional status of the target people group. It is more likely so in elderly people since their dietary habits and inadequate nutrient intakes are of special concern even worse in rural areas. Two popular methods of gathering dietary intake are 24-hour recall and food frequency method (or food frequency questionnaire). In the present study, we conducted both 24-hour recall and food frequency method on 120 rural elderly people $(aged\;65{\sim}74\;years)$, 62 male and 58 female. The dietary intakes were analyzed and the correlation of the dietary intake between 24-hour recall and food frequency method to determine the reliability between two methods. Also each nutrient intake was compared to recommended dietary allowance (RDA) or nutrient reference value (NRV) as appropriate. Even correlation did not show significance between the two methods except for dietary fiber intake (0.65 at p<0.01) and energy-yielding nutrients which mostly showed similar results with nutrient intake level. These support the possible reliability between 24-hours record and food frequency method that is also shown on the cases of most mineral and vitamin intakes. Thus, the food frequency method used in this study for the assessment of nutrient intakes of the elderly people would be reliable for the assessment of the nutrient intake along with the 24-hour recall. Also, the present study results suggested that rural female elderly people would be under optimal nutriture status due to the lower food intake measured by 24-hour recall. The optimal food frequency method would be considered to be developed for the precise nutrient assessment.

This nutrition survey was carried out twice(Spring and autumn) in Sam Chung-Ri, Song Kwang Myun, Soong Ju-Gun. The food intakes of 92 family members were measured by weighing method. Also 45 adults were examined for anthropometric, blood content and blood pressure. The results abtained were summarized as follows; In vegetable foods, the intake of rice was high, but that of legumina and other cereals was low. In animal foods, the intake of milk and eggs was low, and that of oils and fats was very low. However, the food intake between spring and autumn showed remarkable difference. The average intake of calorie, protein, Ca, Fe and vitamin $B_2$ except vitamin $B_1$ and niacin was below the RDAs. The percentage of carbohydrate, protein and fat for energy was 82.2, 11.6 and 6.2%, respectively. The results of anthropometry of height, weight and chestcircumference showed that both sexes Were below Korean Standards. The concentration of Hb & Hct was normal in both sexes, and the rate of anemia was low. The concentrations of plasma glucose, protein, lipids, and blood pressure were normal in both sexes. In case of male, the correlation between plasma albumin and nutrients intake was significant, but the case of female showed different tendency. In case of male, the correlation between weight, height and plasma protein was also significant but the case of female showed different tendency. The rate of parasite infection was very low $(2.17%{\ldots}3.26%)$

Purpose: There is no established formula for estimating renal depths in Korean. As a result, we undertook this study to develop a new formula, and to apply this formula in the calculation of glomerular filtration rate (GFR). Materials and Methods: We measured the renal depth (RD) on the abdominal CT obtained in 300 adults (M:F: 167:133, mean age 50.9 years) without known renal diseases. The RDs measured by CT were compared with the estimated RDs based on the Tonnesen and Taylor equations. New formulas were derived from the measured RDs in 200 out of 300 patients based on several variables such as sex, age, weight, and height by multiple regression analysis. The RDs estimated from the new formulas were compared with the measured RDs in the remaining 100 patients as a control. In 48 patients who underwent Tc-99m DTPA renal scintigraphy, GFR was measured with three equations (new formula, Tonnesen and Taylor equations), respectively, and compared with each other. Results: The mean values of the RDs measured from CT were 6.9 cm for right kidney of the men (MRK), 6.7 cm for left kidney of the men (MLK), 6.7 cm for right kidney of the women (WRK), and 6.6 cm for left kidney of the women (WLK). The RDs estimated from Tonnesen equation were shorter than the ones measured from CT significantly. The newly derived formulas were 12.813 (weight/height)+0.002 (age)+ 2.264 for MRK, 15.344 (weight/height)+0.011 (age)+0.557 for MLK, 12.936 (weight/height)+ 0.014 (age)+1.462 for WRK and 13.488 (weight/height)+0.019 (age)+0.762 for WLK. The correlation coefficients of the RD measured from CT and estimated from the new formula were 0.529 in MRK, 0.729 in MLK, 0.601 in WRK, and 0.724 in WLK, respectively. The GFRs from the new formula were significantly higher than those from the Tonnesen equation significantly, which was the most similar to normal GFR values. Conclusion: We generated new formulas for estimating RD in Korean from the data by CT. By adopting these formulas, we expect that GFR can be measured by the Gates method accurately in Korean.

Purpose: To evaluate the diagnositc value of the absolute and relative renal uptake rates on $^{99m}Tc-DMSA$ renal scan of children with febrile UTI. Method: The absolute and relative renal uptake rates of $^{99m}Tc-DMSA$ were checked in 68 children with febrile urinary tract infection (35 with unilateral focal defect; 13 with bilateral focal defect; and 20 with diffuse bilateral defect) and 49 children with afebrile UTI and normal $^{99m}Tc-DMSA$ renal scan as control. Results: The renal absolute uptake rate in the control group were $21.8{\pm}3.9%(right),\;22.2{\pm}3.9%(left),\;and\;44.2{\pm}7.8%(total)$. The absolute uptake rate gradually increased until the age 12 months and then was stationary. In febrile UTI with unilateral focal defect on the $^{99m}Tc-DMSA$ renal scan, both relative and absolute uptake rates were similarly diagnostic ($41.2{\pm}9.7%,\;16.5{\pm}5.4%$ vs $50.0{\pm}2.6%,\;22.0{\pm}3.9%$, p<0.01). In acute pyelonephritis with bilateral focal defect on the $^{99m}Tc-DMSA$ renal scan, the absolute uptake rate was significantly more diagnostic than the relative uptake rate[$17.3{\pm}5.3%$ (right), $17.4{\pm}5.3%\;(left),\;vs\;21.8{\pm}3.9%,\;(right)\;22.2{\pm}3.9%$, (left)% p<0.01]. In febrile UTI with bilateral diffuse defects on the $^{99m}Tc-DMSA$ renal scan, the absolute uptake rate was significantly diagnostic than the relative uptake rate [$18.1{\pm}3.9%\;(right),\;18.4{\pm}3.8%\;(left),\;vs\;21.8{\pm}3.9%,\;(right)\;22.2{\pm}3.9%$(left), p<0.01]. Conclusion: In the $^{99m}Tc-DMSA$ renal scan, the absolute uptake rate was more useful than the relative uptake rate to evaluate bilateral acute pyelonephritis.

Purpose: Re-188-Hydroxyethylidene diphosphonate (HEDP) is a new cost-effective agent for systemic radioisotope therapy of metastatic bone pain. We investigated the influence of carrier for labeling and biodistribution of Re-188-HEDP using HEDP kit with or without carrier ($KReO_4$). Materials and Methods: The kits (HEDP 15 mg, gentisic acid 4 mg and $SnCl_2.2H_2O_2$ 4.5 mg) with or without carrier ($KReO_4$ 0.1 mg) were labeled with Re-188 solution, made available from an in-house generator by boiling for 15 min. We compared the labeling efficiency and stability of carrier-added and carrier-free preparations of Re-188-HEDP Biodistribution and imaging studies of each preparation were performed in ICR mice ($1.85{\sim}3.7MBq/0.1ml$) and SD rats ($74.1{\sim}85.2MBq/0.5ml$). Results: The carrier-added preparation showed high labeling efficiency (95% at pH 5) and high stability in serum (88%, 3 hr). However, the carrier-free preparation showed low labeling efficiency (59% at pH 5) and low stability (43%, 3 hr). The carrier-added preparation showed high uptake in bone and low uptake in stomach and kidneys. However, the carrier-free preparation showed lower uptake in bone and higher uptake in both stomach and kidneys, which is supposed to be due to released perrhenate. The carrier-added preparation also showed better images with higher skeletal accumulation, lower uptake in other organs and lower soft tissue uptake than the carrier-free preparation. Conclusion: The results of these studies clearly demonstrate that addition of carrier perrhenate is required for high labeling efficiency, stability, bone uptake and good image quality of Re-188-HEDP.
