the results are consistent with the hypotheses that ( a ) chronic nacl restriction increases the transport ability of the distal convoluted tubule independent of changes in tubule structure , ( b ) high rates of ion delivery to the distal nephron cause tubule hypertrophy , and ( c ) tubule hypertrophy is associated with increases in ion transport capacity .
