Effects of dietary calcium level and HISIKIA fusiforme supplementation bone indices and serum lipid levels in ovariactomized rats

초록

The effects of dietary calcuim level and Hijikia fusionforme supplementation on bone indices and serum lipid levels were studied using 36 female Sprague-Dawley rats. After ovariectomy the rats received low Ca diet for 3 weeks, and then divied into six dietary groups and fed low(0.1% Ca), normal(0.5% Ca), high(1.5%, Ca)Ca diets and low, normal, high Ca diets with Hijikia fusiforme supplementation for 3 weeks. Serum Ca levels showed no significant difference by dietary Ca levels and Hijikia fusiforme supplementarion. Alkaline phosphatase activity was significantly increased as dietary Ca levels up. Total cholesterol and TG were not significantly different. HDL-cholesterol showed no significant difference by Hijikia fusiforme supplementation. However the normal and high Ca group showed significantly higher HDL-cholesterol compared to the low Ca group. Urinary hydroxyproline and hydroxyproline/creatinine ratio were not significantly different among groups. The dry weight, wer weight/body weight, length and breaking force of the femur were not significantly different among groups. Ash contents/wet weight of the femur was significantly increased as dietary Ca levels up and significantly higher in Hijikia fusiforme supplementation groups. The Ca content of the femur were significantly higher in the normal and high Ca groups than the low Ca group. However there was no significant difference in Ca content by Hijikia fusiforme supplementation.
