Fig. 3. Effects of cadmium (Cd) exposure on glutathione synthesis rates in gill and
hepatopancreas (HP) cells of oysters estimated as the rates of
cycloheximide-insensitive incorporation of [3H]Gly. Mean values of
glutathione synthesis in the cells exposed to different Cd levels
(x-axis) for 4 h at 20°C are expressed as % of the respective
controls. Vertical bars represent s.e.m. The asterisk denotes values
significantly different from the respective control [P<0.01; the
dagger denotes a marginally significant difference (P=0.09)].
