Figure 1From: Excitatory and inhibitory effects of prolactin release activated by nerve stimulation in rat anterior pituitaryPRL concentrations of sampled perfusate (Mean ± SD, pg/ml). The perfusate was continuously collected as aliquots and measured by RIA. (1) Slices were perfused with KRBGA and the perfusate was sampled every 10 min (n = 5). (2) Slices were perfused with KRBGA and the perfusate was sampled every 1 min (n = 5). (3) TTX (1 μmol/L) perfusion control of (1) (n = 5). (4) TTX (1 μmol/L) perfusion control of (2) (n = 5). K+, prolactin release was evoked by high potassium (60 mmol/L). ** P < 0.01.Back to article page
