Figure 2.
Group data for reflex apnea duration (mean ± S.E.M) after 5-HT i.v. infusion before (control, postGlu and saline) and after injection of different concentrations of AIDA (5, 25 and 50 mM). Injection of 5 mM AIDA (N = 6) significantly prolonged reflex apnea duration only in the first 30 s (5 mM AIDA vs. control, **p = 0.0097). 25 mM AIDA (N = 6) and 50 mM AIDA (N = 8) significantly (*p < 0.03 for each dose at all time intervals) and equivalently (p > 0.1 for difference between doses at all time intervals) prolonged reflex apnea following 5-HT infusion.
