Fig. 2. Glutathione redox chemistry in Z. viviparus liver samples after 2
h of exposure to 18°, 22° and 26°C and after 24 h recovery
(recov.) from these temperatures. (A) Oxidized glutathione (GSSG) content. (B)
Redox potential
E at in situ temperature and in
situ intracellular pH (adopted from
Sartoris et al., 2003;
Larsen et al., 1997),
calculated after Schaffer and Buettner (2001). Values are means ± s.d.,
N=4-7; *significantly different from the unstressed group,
significantly different from the respective recovery group,
P<0.05.
