Fig. 2. Influences of acute late sepsis on endplate potential (EPP) at baseline. Amplitudes of the first EPP and averaged EPP from the 21st to the 50th EPPs (EPP1amp and EPP21–50amp, respectively; A ), quantal content of EPP1and EPP21–50( m 1and m 21–50, respectively; B ), and an indication of EPP run-down (EPP21–50amp/EPP1amp; C ) were significantly ( P < 0.01, each) increased in the cecal ligation and puncture group ( filled columns ) compared with those in the sham group ( open columns ). * P < 0.01 versus sham; n = 30, each.
