Fig. 1. Twitch force and resting tension for ventricular preparations from
yellowtail flounder (A) and Atlantic cod (B) exposed to oxygenated conditions
(
) (flounder, N=6; cod, N=5) and to 35 min of anoxia
followed by reoxygenation ([UNK]) (N=10, for both species). Arrows
indicate times at which anoxia was induced (N2) (20 min) and when
preparations were reoxygenated (O2) (55 min). `a' indicates
significant difference between treatments. `b' indicates a significant
decrease or increase from measurements within the treatment taken 5 min
beforehand.
