The relationship between femur and serum calcium and phosphorus content in osteoporosis / 中国医师杂志

ABSTRACT

Objective To study the relationship between femur and serum calcium and phosphorus content in rat with osteoporosis. Methods We developed animal models with rat experienced bilateral oophorectomy and used inductively coupled plasma atomic emission spectrometry (ICP-AES) to determine calcium and phosphorus content in femur and serum of experimental group as well as control group. Results Calcium and phosphorus contents in femur in experimental group were significantly lower than that in control group[Ca (218.59 ± 10.43) mg/L vs (253.32 ±7.54)mg/L;P( 127.82 ±3.71 )mg/L vs ( 142. 18 ±5.99 ) mg/L, P ＜0. 01], but in serum experimental group it was significantly higher than that in control group [Ca (99.45 ±0.76)mg/L vs (97.56±0.80) mg/L;P (67.68 ± 1.63) mg/L vs (60.00 ± 1.18) mg/L,P ＜0. 01]. Conclusion Femur calcium and phosphorus levels were significantly reduced, which was related to the increase of serum calcium and phosphorus content, and it was one of the causes of osteoporosis.
