Fig. 2. Single and combined effects of barium (Ba; 5 mmol l–1) and
bumetanide (Bu; 100 µmol l–1) on transepithelial ion
secretion in isolated Malpighian tubules of the yellow fever mosquito. After
the usual initial 30 min control period, fluid secreted by the tubules was
removed for analysis with an electron microprobe, and barium and/or bumetanide
was added to the peritubular Ringer solution. Fluid secreted under
experimental conditions was collected at the end of the experiment,
25–70 min after introducing the agent of interest to the peritubular
Ringer bath. Data are expressed as % of control. N=7 for C and Ba;
N=6 for Bu and Ba+Bu. For numeric data, see
Table 1. Asterisks indicate
significant differences (P<0.05). Effects of bumetanide alone are
previously published data (Hegarty et al.,
1991).
