Figure 4From: Age-dependent changes in 24-hour rhythms of catecholamine content and turnover in hypothalamus, corpus striatum and pituitary gland of rats injected with Freund's adjuvantTwenty-four h changes of NE and DA content in hypophysial neurointermediate lobe and of DA content of hypophysial anterior lobe in young and old rats injected with Freund's adjuvant or its vehicle 18 days earlier. Groups of 5–7 rats were killed by decapitation at six different time intervals throughout a 24-h cycle. Shown are the means + SEM. The groups in which significant differences among time intervals were detected by a one-way ANOVA are indicated by their F values in the Figure (n.s.: not significant F).
