Fig. 3. Spontaneous fH of 5°C, normoxia- and
anoxia-acclimated right-atrial preparations during exposure to various saline
solutions devised to simulate or reverse the changes occurring in turtle blood
plasma during 14 days of anoxic submergence. Exposure order for
normoxia-acclimated preparations was as given in the figure, reading from
left-to-right, whereas exposure order for anoxia-acclimated preparations was
as reading from right-to-left. Significant differences (P<0.05) in
fH among saline solutions within an experimental group are
indicated by different letters.
Significant differences
(P<0.05) in fH from a comparable Control
protocol fH. *Significant difference
(P<0.05) in fH between normoxia- and
anoxia-acclimated preparations under simulated in vivo normoxic or
simulated in vivo anoxic conditions. Values are means ±
s.e.m.; N=6 in both experimental groups.
