Some factors affecting Malpighian tubule fluid secretion and transepithelial potential in Locusta migratoria L.
Both fluid secretion and transepithelial potential were stimulated by cAMP. Fluid secretion was unaffected by 5-HT over the concentration range 10(-8)-10(-4) M. The presence of ouabain in the bathing medium effected a decrease in transepithelial potential.
