Figure 2.

Conductance and paracellular transport of [14C]urea in distal colon of K8+/+, +/−, and −/− mice. Distal colon from K8+/+, +/−, or −/− mice was mounted in lucite chambers. Conductance was determined from short circuit current (Isc) and potential difference (P.D.). Conductance (A) and urea fluxes, Jms urea (B), represent the average of two 15-min intervals and are expressed as mean ± SEM. n, number of tissues studied in each group. *, not significantly different from K8+/+.
