Fig. 3. Activities of CS (A–C) and COX (D–F) in hepatocytes prepared from cold- (white bars) and warm- (grey bars) acclimated eelpout (Z. viviparus). Activities were determined in freshly isolated hepatocytes (A,D; N=4) and in cells after incubation at either 4 or 11°C (B,C,E,F; N=5–8) under control conditions (white bars) or with the addition of adenosine (hatched bars). Significant difference between acclimations; ^*significant difference from the control group incubated at the same temperature; significant difference from the corresponding group incubated at 4°C. Values are means ± s.e.m.
