Vasopressin and oxytocin in plasma of veal calves, sheep and pigs after high voltage electrical stunning.

The levels of vasopressin and oxytocin in the plasma of veal calves, sheep and pigs were determined during and after a general epileptiform insult induced by high voltage stunning. Immediately after stunning, a sharp increase in the vasopressin and oxytocin levels was observed in the plasma, followed by a gradual decrease during the next hour. The duration of the general epileptiform insult was correlated (r = 0·79) with the highest measured levels of vasopressin after electrical stunning in the pigs (p ≤ 0·05).

Depressor activity of intracerebroventricularly administered pepstatin in young spontaneously hypertensive rats.

The effect of prolonged intracerebroventricular (i.c.v.

Vasopressin and oxytocin content in cerebrospinal fluid and in various brain areas after administration of histamine and pentylenetetrazol.

The content of vasopressin (AVP) and oxytocin (OXT) in the septum, hippocampus, hypothalamus and cortex was determined at 5 min and 24 hr after peripheral (intraperitoneal) administration of histamine (20.0 mg/kg) and pentylenetetrazol (45.0 mg/kg) and in the cerebrospinal fluid at 24 hr after pentylenetetrazol treatment.

Penetration of neurohypophyseal hormones from plasma into cerebrospinal fluid (CSF): half-times of disappearance of these neuropeptides from CSF.

The penetration of neurohypophyseal peptides after peripheral administration into the cerebrospinal fluid (CSF) was studied in freely moving rats. In addition, the clearance of these peptides from CSF was investigated. Increased concentrations of vasopressin (AVP) in CSF were detectable 2 min after s.

Changes in cerebrospinal fluid levels of vasopressin and oxytocin of the rat during various light-dark regimes.

Levels of arginine-vasopressin (AVP) and oxytocin (OXT) in cerebrospinal fluid (CSF) of rats were determined at various times of the day and the night under normal and changed light-dark conditions. During a regular daily 14 h light and 10 h dark cycle (lights on 06.00 h, off 20.
