Effect of iberiotoxin (100nM) on the afferent arteriolar response to the Nmethylsulfonimide analog of 11,12-EET (11,12-EET-SI, n=5), 11-nonyloxy-undec-8(Z)-enoic acid (11,12-ether-EET-8-ZE, n=5) and 11,12-trans-oxido-eicosa-8(Z)-enoic acid (11,12-tetra-EET-8ZE, n=5). In the presence of 0.5μM norepinephrine, control diameter averaged 16.0 ± 0.9μm and after administration of iberiotoxin averaged 16.2 ± 0.5μm. * Significant difference from control diameter. † Significant difference from the control diameter response to the 11,12-EET analog.
