Effect of Source and Intake Level of Calcium on Serum and Femur in Aged Female Rats

칼슘급원과 섭취수준이 노령 암컷흰쥐의 혈청 및 대퇴골에 미치는 영향

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.
