Figure 8.

Mean data showing the effect of PPADS, a P2X antagonist, on the baseline discharge (A) and the responses of group III afferents to either static contraction (B) or passive stretch (C) in Sham+Sed, Sham+ExT, CHF+Sed, and CHF+ExT rats. (D) The effect of PPADS on the TTI produced by passive stretch or static contraction in Sham+Sed, Sham+ExT, CHF+Sed and CHF+ExT rats. Data are expressed as Mean ± SE. n = 8 − 10/each group. ^*P < 0.05 vs. before, #P < 0.05 vs. Sham+Sed. [Reprinted from Wang et al. (2012). Copyright @ 2012 American Heart Association.
