Fig. 2. Effects of exogenous glucose on resting tension. In females, resting
tension was maintained in media containing 5 or 10 mmol l-1 glucose
but increased in glucose-free (0), 1 and 2 mmol l-1 glucose
conditions (dissimilar letters denote significant differences between
treatments, *P<0.05). There were no significant
differences in resting tension for males at all concentrations tested.
Immature females also showed higher resting tension compared with immature and
sexually maturing males at 0, 1 and 2 mmol l-1 glucose. Values are
means ± s.e.m. (N=8-26 strips per group).
