- Group A: 2 Hz. Group B: 2 Hz + TTX (1 μmol/L). Group C: 10 Hz. Group D: 10 Hz + TTX (1 μmol/L).
- The perfusate was continuously collected as aliquots every 1 min and measured by RIA. Italic data represents results during electrical field stimulation.
- TTX, tetrodotoxin; EFS, electrical field stimulation; K+, prolactin release was evoked by high potassium (60 mmol/L); N, the number of the rat used.
- *Significant changes within group (* P < 0.05, ** P < 0.01).
