Cholinergic innervation of human mesenteric lymphatic vessels.
BACKGROUND The cholinergic neurotransmission within the human mesenteric lymphatic vessels has been poorly studied. Therefore, our aim is to analyse the cholinergic nerve fibres of lymphatic vessels using the traditional enzymatic techniques of staining, plus the biochemical modifications of acetylcholinesterase (AChE) activity. MATERIALS AND METHODS Specimens obtained from human mesenteric l...
متن کاملAnalysis of innervation of human mesenteric vessels in non-inflamed and inflamed bowel--a confocal and functional study.
We investigated the distribution and density of perivascular nerves in human mesenteric arteries and veins and their responses to noradrenaline (NA), ATP and neuropeptide Y (NPY) in control (non-inflamed) and inflamed bowel, using confocal microscopy and in vitro pharmacology. The density of innervation at the adventitial-medial border of arteries and within the medial muscle coat of veins was ...
متن کاملAutonomic innervation of preretinal blood vessels of the rabbit.
The preretinal blood vessels, that is, blood vessels lying on the inner surface of the retina, were observed by SEM examination using digestion methods, TEM examination and fluorescence histochemical examination using the Falck-Hillarp method. The nerve endings on the preretinal arterioles were distributed from the optic disc to the periphery. The longest nerve terminals from the optic disc to ...
متن کاملSympathetic innervation of human mesenteric artery and vein.
BACKGROUND Innervation of blood vessels shows inter-species variability. There are few studies on the innervation of human vessels; thus, healthy mesenteric vessels were studied to identify the expression of immunomarkers and the morphology of sympathetic innervation as the basis for a study of mesenteric vessels in inflammatory bowel disease. METHODS AND RESULTS Electron microscopy studies e...
متن کاملAngiotensinergic Innervation of the Human Right Atrium: Implications for Cardiac Reflexes
BACKGROUND The right atrium is densely innervated and provides sensory input to important cardiocirculatory reflexes controlling cardiac output and blood pressure. Its angiotensin (Ang) II-expressing innervation may release Ang II as a neuropeptide cotransmitter to modulate reflexes but has not yet been characterized. METHODS Intraoperative surgical biopsies from human right atria (n = 7) wer...
