Fig. 7. Effects of 104 mol l1 acetazolamide in
control and HCO3-free saline on fluid secretion
rate by 106 mol l1 5-HT stimulated
Malpighian tubules. Tubules were exposed to acetazolamide (open symbols) or to
the vehicle alone (filled symbols). Arrow indicates addition of acetazolamide
to tubules bathed in (A) control saline (mean ± s.e.m.; N=8)
or (B) HCO3-free saline (mean ± s.e.m.;
N=8).
