FIGURE 2.

Effect of osmotic shock injury on Ca²⁺ transients in FDB fibers preloaded with different concentrations of BAPTA-AM. Data from experiments like those shown in Figure 1 were analyzed. (A), averaged amplitudes of Ca²⁺ transients before OSI presented as (F_max-F₀)/F₀. (B), averaged data for recovery of Ca²⁺ transients at 5 min after OSI. (C), averaged data for frequency of Ca²⁺ waves at 5 min after OSI. (D), % fibers that produced Ca²⁺ waves at 5 min after OSI. N is indicated in each bar. *. p < 0.05 compared to A/J (sham). **, p < 0.05 compared to A/JCr control. Student’s t test was used for A-C; Χ ² was used for (D). VICT = Voltage-induced Ca²⁺ transient.
