چکیده

Gastric ulcer disease remains widespread; a stressful lifestyle and non-steroidal antiinflammatory drugs (NSAIDs) make significant contributions to this pathological situation (Glavin et al., 1991; Hawkey, 2000; Laine et al., 2008). Despite indubitable advances in elucidation of the pathogenesis of gastric ulceration, there are gaps in our understanding of ulcerogenesis, particularly the role of key hormonal system of adaptation: the hypothalamicpituitary-adrenocortical (HPA) axis.

P146: Gamma Aminobutyric Acid (GABA) and its Alterations in Stress

Gamma aminobutyrate (GABA) is a non-protein amino acid that is thought to play an important role in the modulation of the central response to stress. Mechanisms by which GABA may facilitate these responses to stress are metabolic and/or mechanical disruptions. Environmental stresses increase GABA accumulation through cytosolic acidification, induce an acidic pH-dependent activation of glutamate...

Pnm-12: Can Stress Lead to Infertility?

Background: The role that stress plays in infertility remains controversial and despite medical advances a large percentage of infertility remains unexplained. Clinicians and researchers consistently report that infertile women view infertility and its treatment as extremely stressful. Basic science has elucidated the linkages between the hypothalamic-pituitary axis (HPA) and hypothalamic-pitui...

The Realization of the Brain-Gut Interactions with Corticotropin-Releasing Factor and Glucocorticoids

BACKGROUND The brain and the gut interact bi-directionally through the brain-gut axis. The interaction is mediated by the autonomic nervous system and the hypothalamic-pituitary-adrenocortical (HPA) system. The first brilliant demonstration of the brain-gut interactions was the cephalic phase of gastric and pancreatic secretion discovered by Ivan Pavlov, the first physiologist who was awarded t...

The Role of the Endocannabinoids in Suppression of the Hypothalamic- pituitary-adrenal Axis Activity by Doxepin

Objective(s) The mechanism(s) by which antidepressants regulate the hypothalamic-pituitary-adrenal (HPA) axis remain elusive. The endocannabinoid system (eCBs) which exhibits antidepressant potential, appears to regulate the HPA axis activity. Therefore, we aimed to investigate the role of the eCBs in the action of doxepin including its effect on the HPA axis. Materials and Methods Male Wist...
