We investigated in dogs the effect of graded frequencies of electrical vagal stimulation (1.5, 3, 6, and 12 cps) on pancreatic exocrine secretion and on portal blood levels of gastrin, secretin, cholecystokinin (CCK), vasoactive intestinal peptide (VIP), and somatostatin (STS). Stimuli of all four frequencies, each with a duration of 5 minutes, were applied with a secretin background of 0.25 CU/kg-hr, and one stimulatory period of 12 cps was applied without a secretin background. With secretin, a significant, frequency-dependent increase of volume and of pancreatic protein secretion occurred from 3 to 12 cps. Gastrin values increased significantly at all frequencies. VIP and STS increased significantly with 3, 6, and 12 cps. Maximal responses for gastrin, VIP, and STS were observed with 6 cps. Peak values for gastrin and VIP were found during stimulation, whereas STS peaked after the end of the stimulatory period. The integrated responses of gastrin and STS showed significant correlation (P less than 0.01). The results suggest that vagally induced pancreatic response is only partially mediated by gastrin and perhaps VIP, and that endogenous gastrin may be one of the releasing factors for somatostatin. Plasma levels of CCK and secretin did not change after electrical stimulation, which provides direct evidence that their release is unlikely to be under vagal control, and that CCK does not mediate the protein secretion obtained after electrical stimulation of the vagus.

We measured lumbar cerebrospinal fluid (CSF) levels of somatostatin, cholecystokinin, neurotensin, atrial natriuretic factor, vasoactive inhibitory peptide, neuropeptide Y, adrenocorticotrophic hormone, corticotropin releasing hormone, beta-endorphin, metenkephalin, cortisol, alanine, glycine, aspartate, glutamate, taurine, and gamma-aminobutyric acid in 25 inpatients with epilepsy at known interictal and postictal times and in 11 neurologically normal volunteers. There were no significant differences between interictal or postictal complex partial seizures (CPS), postictal generalized tonic-clonic seizures (GTC), and control CSF neuropeptide, cortisol, and amino acid (AA) levels. However, there were nonsignificant trends for CSF levels of several neuropeptides to be increased after CPS and GTC as compared with interictal baseline levels. There were significant correlations between levels of certain CSF neuropeptides or (AAs) and serum antiepileptic drug (AED) levels. Several correlations were noted between CSF levels of AAs, including a correlation between the excitatory neurotransmitters aspartate and glutamate identified only after CPS.
