  • This study was conducted to investigate the effect of various types of calcium sources on calcium metabolism. Sprague-Dawley male rate weighing approximately 82g were divided into 6 groups and fed experimental diets containing about 0.2% calcium for 4 weeks. Perilla leaves, dried sea mustard, mulberry leaves, loach, skim milk powder, and CaCO3 were used as calcium sources for this study. Food intake of experimental groups showed no significant difference from that of control group, but food efficiency ratio were higher in group fed loach as a calcium source. Apparent calcium absorption from perilla leaves, and skim milk powder groups as good as that in CaCO group. Femur length showed no significant difference among exjerimental groups with different calcium sources. The breaking force of bone was higher in loach and dried sea mustard groups. Weight, ash weight, and calcium content of the femur were higher in the loach diet group than in the others. Thus, calcium from not only skim milk powder but also perilla leaves, dried sea mustard, mulberry leaves, and loach appears readily available and all of these can be recommended as calcium sources.

  • This study was performed to investigate the effect of various types of calcium sources on calcium and bone metabolism. Sprague-Dawley male rats weighing approximately 89.3g were divided into 4 groups and fed experimental diets containing 0.5% calcium for 5 weeks. Four different calcium salts were used for the study : calcium phosphate, calcium lactate, calcium gluconate, and calcium carbonate. Food intake showed no significant difference n accordance with the type of calcium salt, but bo요 weight gain and food efficiency were lower in calcium gluconate and calcium carbonate groups. There was significant differences in liver, thymus and epididymal fat pad weight with the of calcium salt ; the calcium gluconate group showed lower values compared to the other groups. Femur and scapular length were higher in calcium lactate and calcium carbonate groups. Wet weight, dry weight, and density of the femur tended to be lower in the calcium gluconate group than the other groups, but this difference was not statistically significant. The calcium content of the other groups. The calcium gluconate group showed higher urinary calcium and lower calcium absorption and balance. In conclusion, calcium and bone metabolism were different according to the type of calcium sources consumed.

  • This study has investigated the bioavailability of calcium in eggshell powder (ESP) for the purpose of reutilizing eggshells as the calcium source. The experiment was designed 2 ${\times}$ 2 factorial method with two sources, CaCO$_3$ and ESP, and two levels, 0.2% and 0.4% calcium. Weanling SD rats were assigned randomly to one of 4 groups and provided by one of the isocaloric, 20% casein based 4 different experimental diets for 4weeks. Deionized water was given and environment was kept from any contamination of minerals. The body weight, diet intake, feed efficiency ratio (FER), bone growth, Ca contents of bones, and apparent absorption were measured. FER (0.38 - 0.40) and kidney weight were not different among groups and the weight and length, Ca content, strength of two bones Tibia and Femur were not affected by Ca sources except Femur Ca content. Ca content of Femur was greater in ESP groups than that of CaCO$_3$ groups. The body weight gain, bone growth, the Ca contents and strength of bones were significantly greater in 0.4% calcium groups suggesting 0.2% calcium is not sufficient for the optimum growth in the growing rats. These results indicate that ESP be a proper Ca source comparable or superior to CaCO$_3$. However the apparent absorption rate of final 3 days of feeding did not support the observed results showing lower rate in ESP than CaCO$_3$ groups. Further study be needed in the absorption aspect.

  • This study was conducted to investigate the status of calcium intake and serum calcium level in perimenopausal women. The age distribution of the subjects was 49-55 years. Daily nutrient intake and dietary sources of calcium were analyzed by a convenient method and a food frequency questionnaire. At the same time, fasting blood samples were collected and serum calcium concentration was measured. The BMD of subjects was measured by Dual Energy X-ray Absorptiometry (DEXA). Fifty percent of the subjects under 50 years of age ($\leq$49 yr group) and 66.9% of the subjects from 50 years and up ($\geq$50 yr group) were classified as osteopenia or osteoporosis. Intake of energy (p<0.001), protein (p<0.05), fat (p<0.05), calcium (p<0.01) was significantly different between $\leq$49 yr group and $\geq$50 yr group. Mean daily intake of calcium was much lower than the Korean RDA : 94.9% in $\leq$49 yr group and 87.4% in $\geq$50 yr group. The average concentration of total calcium in serum was within the normal range in $\leq$49 yr group. Serum calcium concentrations were significantly (p<0.05) different between $\leq$49 yr group and $\geq$50 yr group. It was noteworthy that serum calcium concentration was positively related to the intake of protein, fat and calcium. Lettuce, sea mustard, bean-curd, anchovy, radish and perilla leaf was included among the major sources of dietary calcium. Further investigation is necessary to make sure of the relations between BMD and serum calcium level and calcium intake.

  • The model rats with postmenopausal osteoporosis were comparatively observed with regard to the effects of bovine ash and calcium phosphate on calcium metabolism. The modelling design involved the five week-old week-old female SD-strain rats ovariectomized and fed a low-Ca diet(20% casein, 0.06% Ca and 0.38% P) for three weeks. The rats were divided into five groups, one of which was fed the low-Ca diet(basal), and the rest of which were divided into five groups, one of which was fed the low-Ca diet(basal), and the rest of which were fed four kinds of Ca-supplemental diets(20% protein, 1.06% Ca and 0.8% P) for three weeks. The Ca-suplements diets contained two kinds of Ca sources, bovine bone ash(BBA) or calcium phosphate, tribasic [Ca3(PO4)2] and two kinds of protein sources, casein or isolated soy protein(ISP). The model rats of postmenopausal osteoporosis fed basal diet showed a significant decrease in Ca utilization in reference to serum Ca concentration, breaking force of bone, Ca and P contents of bone, and Ca absorption and retention. However, the supply of Ca for three weeks demonstrated the improved utilization of Ca. One step further, BBA was more effective than calcium phosphate in improving Ca utilization in ISP-fed groups. On the other hand, no significant difference was seen in casein-fed groups. It is to conclude that BBA could be more effective in accelerating Ca utilization under vulnerable dietary or physiological conditions such as vegetable protein intake and osteoprosis.

  • This study was performed to observe how soy protein and calcium in rats fed unsaturated fat-enriched diet affect the total lipid and cholesterol contents of blood and tissues male Sprague-Dawley rats weighing approximately 220g were fed four purified diets which contained 18% (w/w) corn oil, 1% (w/w) cholesterol, two sources of protein : casein or isolated soy protein (ISP) and two levels of dietary calcium : 0.1% or 1.0%, first for four weeks (Expt. 1) and second for eight weeks (Expt. 2). The contents of total lipid, cholesterol and triglyceride in blood, liver, heart and feces were determined. After four weeks feeding, the serum lipid and cholesterol concentration was not significantly different among the groups. After eight weeks feeding, these concentrations were significantly lower in ISP-High calcium group. The serum lipid concentration was influenced by dietary protein sources and calcium levels. These results indicated that the hypolipidemic effects of soy protein and high calcium intake were partly due to decrease in lipid absorption and these effects were not detected at 4 weeks feeding but 8 weeks feeding.
