  1. Group I: 2 Hz. Group J: 2 Hz + TTX (1 μmol/L). Group K: 10 Hz. Group L: 10 Hz + TTX (1 μmol/L).
  2. The perfusate was continuously collected as aliquots every 10 min and measured by RIA. Italic data represents results during electrical field stimulation.
  3. TTX, tetrodotoxin; EFS, electrical field stimulation; N, the number of the rat used.
  4. *Significant changes within group (** P < 0.01).
