Ke. Fogg et al., EFFECTS OF CORPORA CARDIACA EXTRACT, FUROSEMIDE AND ION SUBSTITUTION ON SODIUM AND CHLORIDE FLUX IN PERFUSED MALPIGHIAN TUBULES OF LOCUSTA, Experientia, 49(4), 1993, pp. 296-299
Treatment with the co-transport inhibitor, furosemide decreased Cl-36-
flux across perfused Malpighian tubules of Locusta. However, exclusio
n of Cl-36- from the bathing medium had no effect on Na-22+ flux where
as substitution of bathing medium Na+ by K+ increased Cl-36- flux. Diu
retic extract of corpora cardiaca increased Na-22+ (by 106%) and Cl-36
- (by 335%) fluxes differentially.
