In the in vitro study, it was investigated whether the expression of muscarinic receptors and cholinergic responses were altered in the situation of experimental cystitis. Rats were treated with cyclophosphamide intraperitoneally and the bladders were excised 36-100 h later. Immunohistochemistry and immunoblotting showed all subtypes of the muscarinic(More)
In rat parotid, submandibular and sublingual glands and in ovine parotid and in human labial glands, the expression of muscarinic receptor subtypes was examined by immunoblotting and immunohistochemistry. Functional correlates were searched for in rat salivary glands. In the rat submandibular and sublingual glandular tissues clear signals of muscarinic M1(More)
BACKGROUND The maintenance of the intestinal epithelium is of great importance for the survival of the organism. A possible nervous control of epithelial cell renewal was studied in rats and mice. METHODS Mucosal afferent nerves were stimulated by exposing the intestinal mucosa to capsaicin (1.6 mM), which stimulates intestinal external axons. Epithelial(More)
The effects of muscarinic receptor antagonists on responses to electrical stimulation of the chorda-lingual nerve were determined in pentobarbitone-anesthetized sheep and correlated to the morphology of tissue specimens. Stimulation at 2 Hz continuously, or in bursts of 1 s at 20 Hz every 10 s, for 10 min induced similar submandibular fluid responses (19(More)
In order to functionally characterise the muscarinic vasodilator responses, effects of cholinergic agonists were studied on isolated preparations of the rat submandibular artery and vein and carotid and jugular vessels. Tentatively, a cholinergic regulatory mechanism having different effects on the arterial and venous vessels would enhance vascular fluid(More)
In the in vivo experiments on anaesthetized sheep, it was presently examined whether muscarinic receptor antagonists with diverse selectivity affect the release of VIP in response to electrical stimulation of the parasympathetic chorda tympanic nerve differently, and if the changes in the release could be associated to altered secretory and vasodilator(More)
3 Till Pappa och Ninni, och till minnet av dem som inte fick följa mig hela vägen 4 Abstract Parasympathetic nervous activity is the principal stimulus for evoking fluid responses within salivary glands. Concomitantly to the onset of this response, the blood flow increases. The responses, in particular the vasodilatation, consist of an atropine-sensitive(More)
