Figure 1. Change in plasma pyrophosphate (PPi) concentration after injection of PPi containing tracer [32P]PPi.

Figure 1

(a) Single subcutaneous injection of 80 μmol/kg sodium PPi in three different rats. (b) Single intraperitoneal injections of 0.026 μmol/kg (solid symbols) or 2.6 μmol/kg (open symbols) sodium PPi in a volume of 5 ml/kg. The increment in plasma PPi concentration was calculated from the specific activity of the injected 32PPi.
