Enhanced stress responsiveness has been implicated as a potential mechanism contributing to the pathophysiology of irritable bowel syndrome (IBS), and should be reflected in altered function of the hypothalamic-pituitary-adrenal (HPA) axis and the sympathetic nervous system. Both of these systems can modulate mucosal immune function. The aims of this study(More)
Stress-induced reinstatement of cocaine seeking requires corticotropin releasing factor (CRF) actions in the ventral tegmental area (VTA). However the mechanisms through which CRF regulates VTA function to promote cocaine use are not fully understood. Here we examined the role of GABAergic neurotransmission in the VTA mediated by GABA-A or GABA-B receptors(More)
The author assessed the effect of leucotrienes B4 and C4 and the calcium ionophore A23187 on the adherent reactivity of mononuclear leucocytes in patients with multiple cerebrospinal sclerosis and in controls. The calcium ionophore A23187 in concentrations of 200 nmol/1 - 5 mumol/1 induced inhibition of leucocyte adherence, depending on the concentration(More)
