About the impossibility of a single (ex-)user and survivor of psychiatry position.

Objective: To present the European Network of (ex-)users and survivors of psychiatry and discuss issues of concern among (ex-)users and survivors.

Method: Material from papers and documents published by and discussed among (ex-)users and survivors of psychiatry is used to outline topics of interest.

Results: The European Network of (ex-)Users and Survivors of Psychiatry (ENUSP) was founded in 1991 as an association of national/regional organizations of (ex-)users and survivors of psychiatry.

Effect of endogenous opioids on vagally induced release of gastrin, somatostatin and bombesin-like immunoreactivity from the perfused rat stomach.

The aim of the present study was to evaluate the effect of the opiate receptor antagonist naloxone on vagally stimulated secretion of bombesin-like immunoreactivity (BLI), somatostatin and gastrin from the isolated rat stomach, which was perfused via the celiac artery with Krebs-Ringer buffer. Vagal stimulation was performed for 10 min with 1 ms, 10 V and 2, 5, 10 or 20 Hz, respectively. In control experiments BLI release increased significantly above basal secretion during a stimulation frequency of 10 Hz (1367 +/- 357 pg/10 min; P < 0.
