Active transport of jejunal epithelium at 1 dpi. All values were corrected for the epithelial surface area (corr). (A) Stimulation by forskolin (FSK) resulted in a significantly increased chloride secretory response (∆ISCFSK, corr) in the Znlow group (P ≤ 0.001, n = 8) when compared to the Znmed (n = 9) and Znhigh groups (n = 10). (B) Glucose-induced short-circuit currents (∆ISCGlc, corr) of Znlow (n = 7), Znmed (n = 8), and Znhigh (n = 8) were not significantly different. Note the big spread of individual values in the Znlow group.
