1. 5,8,11,14-Eicosatetraynoic acid (ETYA) inhibited the antigen-induced contractions of tracheal spirals obtained from actively sensitized guinea-pigs. Consistent data were obtained only when the spirals were treated with indomethacin. 2. ETYA did not affect histamine-induced contractions of indomethacin-treated tracheal spirals. 3.

Background: Perivascular adipose tissue (PVAT) exerts anti-contractile effects on visceral arteries by release of various perivascular relaxing factors (PVRFs) and opening voltage-gated K+ (Kv) channels in vascular smooth muscle cells (VSMCs). Palmitic acid methyl ester (PAME) has been proposed as
