Effect of apamin (1μM), charybdotoxin (10nM) and TRAM-34 (1μM) on the afferent arteriolar response to 11-nonyloxy-undec-8(Z)-enoic acid (11,12-ether-EET-8-ZE, apamin, n=5; charybdotoxin, n=4; and TRAM-34, n=5). In the presence of 0.5μM norepinephrine, control diameter averaged 18.6 ± 0.8μm and after administration of inhibitors averaged 18.5 ± 0.7μm. * Significant difference from control diameter.
