TLDR
Together these agents appear to determine the complex physiologic responses to a variety of stressors.Abstract:
Stress stimulates several adaptive hormonal responses. Prominent among these responses are the secretion of catecholamines from the adrenal medulla, corticosteroids from the adrenal cortex, and adrenocorticotropin from the anterior pituitary. A number of complex interactions are involved in the regulation of these hormones. Glucocorticoids regulate catecholamine biosynthesis in the adrenal medulla and catecholamines stimulate adrenocorticotropin release from the anterior pituitary. In addition, other hormones, including corticotropin-releasing factor, vasoactive intestinal peptide, and arginine vasopressin stimulate while the corticosteroids and somatostatin inhibit adrenocorticotropin secretion. Together these agents appear to determine the complex physiologic responses to a variety of stressors.read more

Role of stress and sympathetic innervation in the development of polycystic ovary syndrome.
TL;DR: The participation of stress as an etiological factor for ovarian pathologies throughout animal models and data in patients with polycystic ovary syndrome give strong support for participation of sympathetic nerves in the ovary function both in normal and pathological status.

Effect of electroacupuncture on response to immobilization stress.
TL;DR: Electroacupuncture at HT3 and PC6 points but not at control points significantly reduced the expected increases in BP, HR, and attenuated plasma levels of NE and EPI in response to 3 h of immobilization stress.

Corticosterone, locomotor performance, and metabolism in side-blotched lizards (Uta stansburiana).
TL;DR: It is suggested that elevated levels of corticosterone in response to dominance interactions promote enhanced locomotor abilities, perhaps as a flight response to avoid agonistic interactions, and stressed lizards are characterized by lower resting metabolic rates, which may serve as strategy to conserve energy stores and enhance survival.

TL;DR: In vivo treatment with neutralizing monoclonal antibody against mouse IFN-gamma completely abrogated the increase in splenic NK cell activity induced by ST36 acupoint stimulation, and endogenous beta-endorphin secreted by EA stimulation also plays an important role in the up-regulation of NK cell function.

Mild stress stimulates rat hippocampal glucose utilization transiently via NMDA receptors, as assessed by lactography
TL;DR: These experiments suggest that mild stress activates glutamatergic neurons, which may be less after habituation to stress.

Characterization of a 41-residue ovine hypothalamic peptide that stimulates secretion of corticotropin and beta-endorphin
TL;DR: A peptide with high potency and intrinsic activity for stimulating the secretion of corticotropin-like and β-endorphinlike immunoactivities by cultured anterior pituitary cells has been purified in this paper.

A Syndrome produced by Diverse Nocuous Agents
TL;DR: If the organism is severely damaged by acute non-specific nocuous agents such as exposure to cold, surgical injury, production of spinal shock, excessive muscular exercise, or intoxications with sublethal doses of diverse drugs, a typical syndrome appears, the symptoms of which are independent of the nature of the damaging agent or the pharmacological type of the drug employed.

Simultaneous single isotope radioenzymatic assay of plasma norepinephrine, epinephrine and dopamine.
TL;DR: Modification of the original single isotope radioenzymatic assay of Passon and Peuler permits the direct and simultaneous analysis of norepinephrine, epinephrine and dopamine in plasma samples of 50 μl or less.
