Clonidine, an alpha 2 adrenoreceptor agonist, is used to treat opiate dependent individuals who are experiencing the signs and symptoms of withdrawal. Changes in the apparent number of alpha 2 adrenoreceptors in specific areas of the rat brain have been observed after chronic morphine administration. In the present study, the effects of chronically administered morphine sulfate upon alpha 2 adr...

BACKGROUND Parkinson's disease (PD) is a progressive neurodegenerative disorder of the central nervous system, observed in patients aged older than 50 years. In this study, we review interactions between therapies used in PD and selected antihypertensive agents. Moreover, in view of the lack of evidence-based recommendations regarding the pharmacotherapy of arterial hypertension in PD patients,...

AIMS The interaction between coronary β(2)-adrenoreceptors and segmental plaque burden is complex and poorly understood in humans. We aimed to validate intracoronary (IC) salbutamol as a novel endothelium-dependent vasodilator utilizing intravascular ultrasound (IVUS), and thus assess relationships between coronary β(2)-adrenoreceptors, regional plaque burden and segmental endothelial function....

In a wide range of human diseases of inflammatory nature like Crohn's disease, pathology is mediated in part by pro-inflammatory cytokines like tumor necrosis factor-alpha (TNF) or interferon-gamma. We show here that a commonly used generic antidepressant bupropion, in wide use worldwide to treat depression in humans for a decade now, profoundly lowers levels of TNF, interferon-gamma, and inter...

Jasminum amplexicaule Buch.-Ham. (Oleaceae) has been commonly used in the traditional medicine in dysentery, diarrhoea and bellyache in China. In the present work, the methanol extract of Jasminum amplexicaule (JME) was examined for pharmacology on human colonic epithelial cell line T84 by the short-circuit current technique. The results showed that pretreatment of T84 cells with JME produced a...
