Serum calcium concentrations of C3H/Fg, C3H/HeJFg, AKR/Fg, A/Fg, and LCS/Fg mice were compared at 4 and 7 mo of age. In the C3H/Fg and A-strain mice, calcium levels did not differ significantly between the 2 strains nor between the 2 age groups. The C3H/HeJFg, LCS/Fg, and C57BL/Fg strains formed a distinct group with similar calcium levels, but at a significantly higher level than C3H/Fg and A/Fg group. Again there was no significant difference between the 4- and 7-mo groups. The AKR/Fg strain was distinct from both groups in that higher calcium levels characteristic of the second group (C3H/HeJFg, LCS/Fg, and C57BL/Fg, were seen at 4 mo of age, but lower calcium levels similar to those of the C3H/Fg and A/Fg strains were found at 7 mo of age.
在4月龄和7月龄时比较了C3H/Fg、C3H/HeJFg、AKR/Fg、A/Fg和LCS/Fg小鼠的血清钙浓度。在C3H/Fg和A系小鼠中，两个品系之间以及两个年龄组之间的钙水平均无显著差异。C3H/HeJFg、LCS/Fg和C57BL/Fg品系形成了一个钙水平相似的独特组，但显著高于C3H/Fg和A/Fg组。同样，4月龄组和7月龄组之间也没有显著差异。AKR/Fg品系与两组均不同，其在4月龄时呈现出第二组（C3H/HeJFg、LCS/Fg和C57BL/Fg）特有的较高钙水平，但在7月龄时发现其钙水平较低，与C3H/Fg和A/Fg品系相似。
