Fig. 3. Glucose (A), glycogen (B) and 
-amino acid (C) levels in hindbrain
(Hb), hypothalamus (Hy), and Brockmann bodies (BB) of rainbow trout sampled 6
h after intraperitoneal injection (IP treatment) of 5 ml kg–1
of Cortland saline alone (control, C) or saline containing
L-(+)-lactate (L22.5, 22.5 mg kg–1 or L45, 45 mg
kg–1), sodium oxamate (OXA, 22.5 mg kg–1) or
D-glucose (GLU, 500 mg kg–1), or 6 h after
intracerebroventricular injection (ICV treatment) into the third ventricle of
1 µl 100 g–1 body mass of Cortland saline alone (control,
C) or containing D-glucose (GLU, 400 µg
µl–1) or L-(+)-lactate (L400, 400 µg
µl–1). Results are shown as percentages of control values
(control=100%, dotted line). Each value is the mean ± s.e.m. of
N=11 (IP treatment) or N=8 (ICV treatment) fish per group.
Different letters indicate significant differences among treated groups within
each tissue (one-way ANOVA, P<0.05). *Significantly
different from control (dotted line) in IP treatments (P<0.05);
significantly different from control (dotted line) in ICV
treatments (P<0.05).
