Immobilization stress-induced thymocyte apoptosis in rats
Life Sciences, 2001Immobilization 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.

Immobilization stress induces XBP1 splicing in the mouse brain
Biochemical and Biophysical Research Communications, 2019Cells activate the unfolded protein response (UPR) to cope with endoplasmic reticulum (ER) stress. In the present study, we investigated the possible involvement of psychological stress on UPR induction in the mouse brain. When mice were exposed to immobilization stress for 8 h, XBP1 mRNA splicing was significantly induced in the hippocampus, cortex ...

Hemodynamic changes in immobilization stress
Bulletin of Experimental Biology and Medicine, 1985In 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, 2002Forced 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, 2004Central 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.

Immobilization stress responses in adult rats exposed in utero to immobilization
Stress and Health, 2011AbstractThe present study investigated the influence of immobilization prenatal stress on adult male rats, with the same postnatal stress, on the immune parameters and its relation with plasma corticosterone (COR) and glucose levels. To study the immunity parameters, profiles of the leucocytes, size of spleen and number of the mononuclear cells of this

Effects of Pyridoxine on Mice after Immobilization Stress
Annals of Nutrition and Metabolism, 1974A group of 28 female albino mice, CF-1 strain, 3–6 weeks old, were injected with 1.11mg/kg body weight pyridoxine, and subsequently were restrained for 24 h in individual restraining cages. One half was sacrificed immediately after release and the other half 24 h later.

Testicular function in rats following immobilization stress
International Journal of Gynecology & Obstetrics, 1988AbstractStress is believed to influence male reproductive activity. Male rats were subjected to immobilization stress for 2 h/day for 30 days to assess the effects of stress on testicular function. Net mass of the testes, epididymes and the seminal vesicles, sperm morphology, number of epididymal sperms and percent progressive motility of the sperms ...
