Angiotensin II stimulates absorptive Na⁺ flux in mouse jejunum. Sections of mouse jejunum were mounted in Ussing chambers and matched for transepithelial electrical resistance (differed by less than 20%). One set was treated with 1 nM AII on the serosal side and mucosal (m) to serosal (s) and s-to-m fluxes measured over the next 30 min. Values are means ± SEM for six separate experiments. * p < 0.05 compared with untreated tissues by paired Student's T test.
