Fig. 7. Relationship between sarcoplasmic reticulum Ca2+levels as assessed by mag-fluo-4 fluorescence intensity and occurrence of Ca2+paradox in Control, Post, and Postlong applications of sevoflurane. (A ) Distribution of mag-fluo-4 F/F0in myocytes without (red squares ) or with (blue squares ) occurrence of Ca2+paradox in Control (a ), Post (b ), and Postlong applications (c ) of sevoflurane. Data for Control, Post, and Postlong are the same as shown in fig. 6B. Means and 95% CIs are also presented to the right of respective distributions, except for the data for Postlong, where there was only one myocyte that underwent the Ca2+paradox. *P < 0.05 compared between the groups with and without Ca2+paradox in Control. (B ) Percentage incidence of the Ca2+paradox in three arbitrary groups of mag-fluo-4 F/F0value, for Control and Post application of sevoflurane.
