Fig. 3 . Twitch force and resting tension for ventricular preparations from
Atlantic cod subjected to anoxia and reoxygenation, and treated with agents to
affect KATP-channel activity. Arrows indicate times at which anoxia
was induced (20 min) and when preparations were reoxygenated (55 min). (A)
DMSO treated (diamonds) (N=13). (B) Glibenclamide-treated (squares)
(N=8). (C) Diazoxide treated (hexagons) (N=5). (D)
5HD-treated (triangles) (N=5). `b' indicates a significant change
from measurements within the treatment taken 5 min beforehand.
