Fig. 2. (A) Plasma calcium levels (N=7 for the short-term experiment and
N=10 for the long-term experiment) show the strict control of the
ionic fraction, which only slightly, but significantly decreased after
long-term calcium constraint in both water and diet. (B) In accordance, plasma
sPTHrP decreased significantly in group d compared to controls. Asterisks
indicate significant difference (P<0.05) from control group a.
Values are means ± s.d. SW, full strength seawater; DSW, diluted
seawater.
