Immobilization stress-induced thymocyte apoptosis in rats

Life Sciences, 2001
Immobilization of rats is a well known model of emotional stress. We studied apoptosis in rat thymocytes during immobilization for 2-8 hours (h). Terminal deoxynucleotidyl transferase-mediated dUTP-biotin nick end labeling (TUNEL)-positive cells increased with time of immobilization.

Effect of Immobilization Stress on Gonadotropins and Sex Steroids

open access: yesJournal of Evolutionary Biochemistry and Physiology, 2003
The effects of the acute immobilization stress on follicle-stimulating hormone (FSH), luteinizing hormone (LH), estradiol, and testosterone levels in rats were evaluated. The male and female rats were grouped in control and stress groups (7 animals in each group).

Hemodynamic changes in immobilization stress

Bulletin of Experimental Biology and Medicine, 1985
In chronic experiments on 75 Wistar, August and randombred rats hemodynamic changes were examined during 30-hour immobilization stress. The ECG was recorded and arterial blood pressure measured. The basic hemodynamic characteristics were determined with the help of the previously implanted ultrasonic blood flow probes.

Effect of electroacupuncture on response to immobilization stress

Pharmacology Biochemistry and Behavior, 2002
Forced immobilization is a simple and effective stressor which produces large increases in heart rate (HR), blood pressure (BP), and plasma levels of norepinephrine (NE) and epinephrine (EPI). This study investigated the effects of electroacupuncture on BP, HR, and plasma catecholamine levels in rats challenged with immobilization stress.

THE EFFECT OF IMMOBILIZATION STRESS ON SENSORY GATING IN MICE

International Journal of Neuroscience, 2004
Central sensory filtering processes can be demonstrated using a paired stimulus paradigm. Normal humans show a diminished, vertex-recorded mid-latency (50 ms) of auditory evoked potential to the second of paired clicks (0.5 s apart), a phenomenon termed as auditory gating. A loss of 50 ms in auditory gating is strongly related to psychosis.
