Fig. 7. Changes in hemolymph Na+ (A) and Cl- (B)
concentrations of eyestalkless Astacus leptodactylus 8 h and 24 h
following injection of high-performance liquid chromatography (HPLC) fractions
(10 SGequiv) corresponding to zones Z1 (N=8), Z2 (N=8) and
Z3 (N=8) (see Fig.
4A). Each column represents the mean ± S.E.M. of the
increase in ion concentration compared with the control. Statistical
comparison with controls injected with a Van Harreveld saline (N=6):
*P<0.05; **P<0.01; ***P<0.005.
