Corticosterone and prolactin responses to predictable and unpredictable novelty stress in rats.

abstract：:Rats were instrumented with arterial catheters and directional-pulsed Doppler flow probes for assessment of blood pressure, heart rate, and blood flow in the renal, mesenteric, and hindquarter vascular beds. Subjects were tested in an intermittent shock procedure under paired and isolated social conditions and the car...
