Fig. 3. Time course of the effect of injection of erythrocyte-enriched blood on Hct
and
O2 in
chicken embryos. Injection occurred 5 min after measurement of pre-injection
values. (A) Increases in Hct following injection of 400 µl of
erythrocyte-enriched blood. Asterisks indicate values significantly different
from control Hct at each day of development. (B) Effects of Hct elevation on
O2. No
post-injection measurements differed significantly from control at any
developmental stage. Mean values ± 1 s.e.m.
