Fig. 3. Ventricular enzymes in relation to anemia and cold acclimation. The data
for each enzyme is shown as both specific activity (left panels) and total
activity (right panels). For each enzyme, the first pair of bars is from
animals sacrificed at 4 weeks, with the phenylhydrazine injected group shown
as an solid bar. This comparison reflects the effects of anemia alone. The
second set of bars represents the influence of anemic pre-treatment on the
effects of cold-acclimation. The effects of temperature alone are apparent by
comparing the solid bars. Based on ANOVA, followed by Tukey's post-hoc, we
identified groups that were significantly different from controls at 4 weeks
(*) or (
) phenylhydrazine treated at 4
weeks.
