This study was performed to investigate the effect of dietary dried anchovy and non-fat dried milk on serum and femur Ten months old female rats were divieded into 6 groups(ST, A-middle, A-high, M-middle, M-high, A+M), and fed the diet containing different level of food calcium for 8 weeks. The results obtained were summerized as follow: 1. The rats' weight gain were not significantly different from the fed groups, but food intake were significantly higher or lower level in the group of A-high than the other groups. 2. Serum calcium concentration was significantly increased in the A-middle group, the M-high group were significantly decreased. Serum phosphorous contents of M-high group were increased significantly higher than ST group. The serum magnesium contents were increased significantly higher than in the A-middle group. Serum iron contents of other experimental groups were significantly higher than ST group. All experimental groups were significantly lower copper contents in serum than ST group. 3. The more rats took dried anchovy and non-fat dried milk, the longer the length of femur. But this trend is not statistically difference. In the breaking force of left femur, most of all experimental group were stronger than ST group. 4. The calcium, phosphorous contents of ash, dry, wet weight of right femur in A+M group were higher than any other groups.

Background: The aim of the study was to determine whether the expression of baseline phosphorus (P) and magnesium (Mg) levels were prognostic in terms of stage and overall survival (OS) in newly diagnosed non-small cell lung cancer (NSCLC) and small cell lung cancer (SCLC) patients. Materials and Methods: Retrospectively, 130 patients were selected at the time of diagnosis oflung cancer (100 with NSCLC and 30 with SCLC), before the initialization of any chemo-radiotherapy. The median age was 67 (range 29-92). IA, IB, IIA, IIB, IIIA, IIIB and IV stages were present in 3, 4, 19, 6, 25, 8, and 65 patients, respectively. After centrifugation, the levels of serum P and Mg were measured using the nephelometric method/ photometry and evaluated before any type of treatment. Results: Higher than normal levels of P were found in 127/130 patients, while only four patients had elevated Mg serum values. In terms of Spearman test, higher P serum values correlated with either stage (rho=- 0.334, p<0.001) or OS (rho=-0.212, p=0.016). Additionally, a significant negative correlation of Mg serum levels was found with stage of disease (rho=-0.135, P=0.042). On multivariate cox-regression survival analysis, only stage (p<0.01), performance status (p<0.01) and P serum (p=0.045) showed a significant prognostic value. Conclusions: Our study indicated that pre-treatment P serum levels in lung cancer patients are higher than the normal range. Moreover, P and Mg serum levels are predictive of stage of disease. Along with stage and performance status, the P serum levels had also a significant impact on survival. This information may be important for stratifying patients to specific treatment protocols or intensifying their therapies. However, larger series are now needed to confirm our results.

아연의 공급수준이 다량 무기질 함량에 미치는 영향을 알아보기 위해 흰쥐를 대상으로 아연을 결핍, 적정, 과잉 수준으로 공급하여 혈청 및 조직의 칼슘, 마그네슘, 나트륨, 칼륨함량을 분석하였다. 아연 공급수준을 달리했을 때 혈청의 다량 무기질 함량은 유의적인 차이를 보이지 않았지만 간과 비장에 영향을 주는 것으로 나타났다. 특히 아연의 결핍은 간의 칼슘 함량을 감소시키는 영향을 주었고, 아연의 과잉은 비장 마그네슘과 칼륨 함량을 감소시키는 결과를 나타냈다. 결론적으로 아연의 결핍과 과잉이 간과 비장의 다량 무기질함량에 영향을 주는 것으로 나타났는데, 특히 아연의 결핍이 더 많은 조직 내 무기질 함량 변화를 가져왔다. 그러나 본 연구에서는 아연의 결핍수준을 적정수준의 50%, 그리고 과잉을 200%로 설정하였으나 앞으로 좀 더 세분화된 아연의 결핍과 과잉 수준에 대한 체계적인 연구가 필요하다고 사료 된다.

Magnesium(Mg) plays an important role in lipid metabolism and Mg deficiency but Ca sufficiency Increases serum cholesterol and triglyceride. The relationships of serum Mg, Ca, Ca/Mg ratio with lipids was examined in 79 female college students in Choong-Nam area. Subjects were divided into underweight, normal and overweight groups according to their BMI. The average age, body weight, height and BMI were 21.9yr, 55.9kg, 158.5cm and 22.62kg/$m^2$ respectively. Height was not different between groups. Serum cholesterol and LDL-cholesterol concentrations were significantly lower in the underweight group than other groups. BMI had positive correlations with LDL-cholesterol, atherogenic index (AI) and LDL-cholesterol/HDL-cholesterol ratio(LPH), and negative correlations with HDL-cholesterol/total cholesterol ratio. Serum minerals (serum Mg, Ca, Ca/Mg ratio) and serum lipid concentrations were not significantly different between groups. However, there was a tendency of increasing serum Mg level with increasing serum HDL-cholestrol, HDL-cholesterol/total cholesterol ratio and decreasing serum LDL-cholesterol, LPH, total cholesterol/HDL-cholesterol ratio(TPH) and AI. And there was a tendency of increasing serum Ca level with increasing serum HDL-cholesterol/total cholesterol ratio and decreasing serum triglyceride, LDL-cholesterol, LPH, TPH and AI. And there was a tendency of increasing serum Ca /Mg ratio level with decreasing triglyceride, serum LDL-cholesterol and TPH. This study was limited within serum levels of minerals (serum Mg, Ca and Ca/Mg ratio), serum lipids concerned with CHD, therefore I hope there will be wider efforts to consider about the dietary levels of minerals for presentation of the connection between dietary Mg, Ca and serum lipids.

The purpose of this study was to compare the mineral status of postmenopausal vegetarian women with those of the omnivores, and to investigate the relationship between dietary pattern and minerals status in postmenopausal Korean women. The research group was composed of vegetarian women (n = 38), all of them were seven day adventists, who had been on vegetarian diet over 20 yrs. Their anthropometric measurements, dietary intakes, and blood mineral concentrations were compared to age matched omnivores controls (n = 38). The average age of vegetarians and omnivores were 60.7 yrs and 60.5 yrs, respectively and there was no significant difference. The mean daily energy intake of vegetarians and omnivores were 1518.5 kcal and 1355.5 kcal, respectively and their was no significant difference. The mean calcium intake of vegetarians (492.6 mg) was not significantly different from that of omnivores (436.6 mg). The vegetarians consumed significantly greater quantities of magnesium (p < 0.001), iron (p < 0.001), copper (p < 0.001), manganese (p < 0.001) and dietary fiber (p < 0.05). There were no significantly differences in serum calcium, magnesium and manganese levels between vegetarians and omnivores. However, serum levels of phosphorus (p < 0.01), iron (p < 0.05), ferritin (p < 0.01), zinc (p < 0.001) and copper (p < 0.05) were significantly lower than those of omnivores. In conclusion, vegetarian postmenopausal women may have low bioavailability of iron, zinc and copper. Therefore it was needed that further study on mineral bioavailability of vegetarian diet.

It is thought that calcium (Ca) and magnesium (Mg) may be related to mental disorders such as depression; however, there have been few studies investigating the association between Ca and Mg nutrition status with depression in middle-aged female adults. Study subjects in this study included 105 women between the ages of 41 and 57 years. The subjects were divided into three groups according to the Zung Self-rating Depression Scale (SDS) score: Group I (SDS score < 33 percentile; n = 32), Group II (33 percentile ${\leq}$ SDS score < 67 percentile; n = 37), and Group III (67 percentile ${\leq}$ SDS score; n = 36). Anthropometric measurements, dietary intake survey using 3-day dietary records, SDS questionnaire and measurement of serum Ca and Mg were obtained and analyzed. No differences were observed in Ca, plant Ca, and Mg intake among the three groups. However, animal Ca intake by Group III was 141.3 mg, which was significantly lower than 207.6 mg by Group I and 198.3 mg by Group II (P = 0.0345). There were no significant differences in serum levels of Ca, and Mg among the three groups. Correlation analysis indicated that the SDS score had negative correlations with Ca intake (r = -0.2927, P<0.01) and animal Ca (r = -0.3411, P<0.001) after adjusting for age, menopause and energy intake. In conclusion, dietary Ca and animal Ca had negative associations with SDS score among middle-aged Korean female adults. Additional analysis of factors related to the association of calcium and magnesium nutritional status and depression is necessary.

This study was performed to investigate the influence of dietary fibers from the whole foods on the serum lipid level and bowel function in rats. The fiber sources of experimental diets were prepared by drying and milling of cereal(rice bran), vegetables(Korean cabbage, radish), fruit(apple), and sea weeds(laver, sea tangle). Each of fiber sources was mixed into the diet to make the 5% level of total dietary fiber. Male rats of Sprague-Dawley strain were blocked into 8 groups : FF, CC, CE, V1, V2, ER, S1, and S2. The animals were fed ad libitum each of experimental diets for 4 weeks. Serum triglyceride level was not significantly different among groups. The laver group showed the lowest level in the serum total cholesterol. The Korean cabbage group showed the highest level in the serum HDL cholesterol. The longest transit time was observed in the fiber free group and the shortest transit time was observed in the sea tangle group. Absorption rates of calcium were especially lower in the Korean cabbage and the sea tangle groups than the other groups. Magnesium and phosphorus absorption rates were influenced by SDF(Soluble Dietary Fiber) intake and TDF(Total Dietary Fiber) intake, respectively. Mucosa weight in the small intestine showed the tendency to increase by increasing of IDF (Insoluble Dietary Fiber) intake. especially the Korean cabbage group was the heaviest. The activity of maltase in the mucosa of small intestine was the lowest in the radish group.

본 연구는 우리나라 도축장 현실에서 출하 전 마그네슘 단기 첨가 급여가 돈육 육질을 개선시키고 PSE 돈육 발생을 억제시킬 수 있는지를 구명하기 위하여 거세비육돈(Landrace) 60두를 대조구(MgSO₄ 무첨가구)와 MgSO₄ 급여구로 30두씩 나누어 도축 전 5일 동안 사료와 물을 무제한 급여하여 6일째 도축장으로 수송한 후 2시간 내에 도축하였다. 도축 전 MgSO₄ 첨가 급여는 도축 시 혈중 마그네슘 함량에 영향을 미치지 않았으며, 혈중 스트레스 관련 호르몬(adrenaline, noradrenaline) 역시 마그네슘 급여구와 대조구 사이에 차이가 없었다. 사후 초기 pH는 대조구가 더 높았고, 최종 pH는 유의적인 차이가 없었다. 사후 도체온도는 도축 직후 MgSO₄ 급여구가 더 높았으나 3시간과 6시간에는 비슷하였다. PSE 발생율은 대조구 30%, 마그네슘 급여구 23.3%로 마그네슘 급여구가 약간 낮은 경향을 보였으나 드립로스와 육색 명도에는 차이가 없었다. 비록 본 연구에 공시된 비육돈의 유전적 배경과 도축 전 비육돈의 취급방법이 기존 보고자들과 달랐지만 우리나라의 현실적인 여건을 고려할 때 마그네슘 첨가급여에 의해 돈육 육질을 개선하는 방법이 확립된다면 돼지 사육업자나 가공업자에게 큰 이익을 가져다줄 것이므로 마그네슘 효과를 극대화시킬 수 있는 방법을 찾아낸다면 경제적인 방법이 될 것으로 보인다.
