Correlation of changes in urinary K⁺ and ammonia excretion in control and IC-Rhbg-KO mice in response to K⁺-free diet. A: urinary K⁺ excretion in response to K⁺-free diet in control and IC-Rhbg-KO mice. Urinary K⁺ excretion decreased rapidly in response to the K⁺-free diet and did not differ significantly between control and IC-Rhbg-KO mice on any day of the K⁺-free diet (P = NS; N = 8 in each group). B correlates the change in urinary ammonia with the change in K⁺ excretion in response to K⁺-free diet in control and IC-Rhbg-KO mice. The correlation differed significantly in control and IC-Rhbg-KO mice.
