(A) A channel recording showing the effect of AA on BK channels in the CCD in the presence of 5 μM indomethacin (top), DDMS (middle), or 10 μM MS-PPOH (bottom). The experiments were performed in a cell-attached patch in the CCD from rats on an HK diet. The holding potential was 0 mV, and the channel closed level is indicated by C. (B) The effect of 10 μM AA on BK channels in the presence of 5 μM indomethacin (Indo), 5 μM DDMS, and 10 μM MS-PPOH. *Significantly different from the corresponding control value.
