Effect of environmental stress and immobilization on stress physiological variables in farmed mink

Behavioural Processes, 1991
The effect of cage size and nest box environment on plasma cortisol, number of eosinophil leucocytes, and on frequency of leucocyte groups was measured on 132 farmed mink. The experiment included three cage sizes (0.10 m(2), 0.27 m(2), and 1.1 m(2)) and cages with and without nest boxes. Furthermore, the effect of daily immobilization a mink trap for 5

Effects of Immobilization Stress on Renal Sympathetic Neurotransmission

Clinical and Experimental Hypertension. Part A: Theory and Practice, 1992
The effects immobilization stress on renal sympathetic neurotransmission as well as on heart, spleen and adrenal catecholamine content were examined in the rat. A single 2.5 hr stress period produced significant increases in blood pressure, heart rate, plasma norepinephrine and plasma epinephrine concentrations.

Immobilization stress-induced anorexia is mediated independent of MyD88

NeuroReport, 2016
MyD88 is an adaptor protein for the toll-like receptor, which is involved in regulating innate immune function. Lipopolysaccharide-induced activation of toll-like receptor 4 signaling induces hypothalamic signal transducer and activator of transcription 3 (STAT3) phosphorylation and anorexia through MyD88.

Immobilization Stress and Direct Glucocorticoid Effects on Rat Septohippocampus

International Journal of Neuroscience, 1988
The rat septohippocampal cholinergic system to a large extent regulates the adaptive physiological and behavioral response to stress. The mesoseptal dopaminergic (DA) system, one of the converging inputs to the lateral septum, exerts a tonic inhibitory action on the septohippocampal cholinergic neurons.

Immobilization Stress Induces BDNF in Rat Submandibular Glands

Journal of Dental Research, 2006
Brain-derived neurotrophic factor (BDNF) promotes survival and differentiation of the cells of the central and peripheral nervous systems. BDNF has been identified in non-neural tissue, including the heart, lung, platelets, lymphocytes, and lacrimal glands. Immobilization stress modifies BDNF mRNA expression in some organs.

Stress of Immobilization: Description and Validation of a Restraining Technique for Rats

Psychological Reports, 1981
Various techniques have been developed over the past several years to study the effects of the stress of immobilization on the rat. The technique proposed in this paper provides effective restraint. It has the added advantage that potentially contaminating effects of uncontrolled secondary stressors are limited.

Effects of immobilization stress on shock discrimination performance in rats

Physiology & Behavior, 1982
It has been suggested that acute stress induces analgesia in rats and mice. However, stress can have a myriad of debilitating effects on organisms, and it is not clear whether stress decreases the perceived intensity of the painful stimulus (i.e., a change in sensitivity) or decreases the willingness or ability of the organism to carry out the ...

Mechanism of oxidative stress in skeletal muscle atrophied by immobilization

American Journal of Physiology-Endocrinology and Metabolism, 1993
To clarify the mechanism of oxidative stress in skeletal muscle atrophied by immobilization, we measured the activities of antioxidant enzymes and xanthine oxidase (XOD) and carried out the cytochemical study of hydrogen peroxide in a typical slow red muscle, the soleus.

Involvement of dynorphin in immobilization stress-induced antinociception in the mouse

European Neuropsychopharmacology, 2000
The effect of antiserum against [Met(5)]-enkephalin, [Leu(5)]-enkephalin, beta-endorphin, or dynorphin A-(1-13) administered intracerebroventricularly (i.c.v.) or intrathecally (i. t.) on immobilization-induced antinociception was studied in ICR mice. Antinociception was assessed by the tail-flick assay. Immobilization of the mouse increased inhibition

Anti-stress effect of astragaloside IV in immobilized mice

Journal of Ethnopharmacology, 2014
Astragaloside IV, a major component extracted from the roots of Astragalus membranaceus (AM), possesses anti-inflammatory, anti-oxidative, anti-fibrotic, anti-infarction and immunoregulatory effects. To clarify anti-stress effect of AM, anxiolytic and anti-inflammatory effects of 80% ethanol extract of AM and astragaloside IV were investigated in ...
