The complexities of the cardiovascular actions of cannabinoids

MD Randall, DA Kendall… - British journal of …, 2004 - Wiley Online Library
The cardiovascular actions of cannbinoids are complex. In general they cause vasorelaxation
in isolated blood vessels, while in anaesthetised animals they cause multiphasic …

Endocannabinoids and the haematological system

MD Randall - British journal of pharmacology, 2007 - Wiley Online Library
Endocannabinoids are blood borne and may also be secreted by the endothelium. Accordingly,
there has been interest in the interactions between (endo)cannabinoids and blood cells. …

Novel time-dependent vascular actions of Δ9-tetrahydrocannabinol mediated by peroxisome proliferator-activated receptor gamma

…, AJ Bennett, DA Kendall, MD Randall - Biochemical and …, 2005 - Elsevier
Cannabinoids have widespread effects on the cardiovascular system, only some of which

Testosterone‐induced vasorelaxation in the rat mesenteric arterial bed is mediated predominantly via potassium channels

…, DA Kendall, MD Randall - British journal of …, 2002 - Wiley Online Library
We have investigated the involvement of nitric oxide and K + channels in the vasorelaxant
responses to physiologically‐relevant concentrations of testosterone in the rat isolated …

An endogenous cannabinoid as an endothelium-derived vasorelaxant

MD Randall, SPH Alexander, T Bennett… - Biochemical and …, 1996 - Elsevier
Since the identification of nitric oxide (NO) as an important mediator of endothelium-dependent
