Figure 5.
Addition of exogenous arachidonic acid (AA) to the CNT lumen in the absence of NaCl caused dose-dependent dilation of the attached Af-Art. *** P < 0.001 vs. preconstricted Af-Art diameter. The maximal vasodilation was similar to that achieved by CTGF induced with 80 mmol/L NaCl in the lumen of the CNT.
