Functional characterisation of alpha(1)-adrenoceptors in denervated rat vas deferens
(Springer, 2003-07-01)
We investigated whether or not surgical denervation of the rat vas deferens changes the alpha(1)-adrenoceptor subtypes involved in the contractions to noradrenaline. Denervated vas deferens was approximate to22 times more ...
Effects of myenteric denervation on extracellular matrix fibers and mast cell distribution in normal stomach and gastric lesions
(Biomed Central Ltd., 2010-06-22)
Background: In this study the effect of myenteric denervation induced by benzalconium chloride (BAC) on distribution of fibrillar components of extracellular matrix (ECM) and inflammatory cells was investigated in gastric ...
Denervation supersensitivity to phenylephrine in guinea-pig vas deferens in vivo and in vitro - Functional studies on alpha(1)-adrenoceptors
(Elsevier B.V., 1999-03-01)
The objective was to estimate alterations in adrenergic receptor sites of guinea pig vas deferens, in vivo and in vitro, induced by chronic denervation. The denervation process induced an increased sensitivity (3-fold at ...
Reinnervation following catheter-based radio-frequency renal denervation
(Wiley-Blackwell, 2015-05-01)
What is the topic of this review? Does catheter-based renal denervation effectively denervate the afferent and efferent renal nerves and does reinnervation occur? What advances does it highlight? Following catheter-based ...
Influência da vagotomia gástrica proximal sobre a zona de alta pressão esofagogástrica do cão.
(1988-10-01)
The influence of parietal cell vagotomy (PCV) on esophagogastric high pressure zone (HPZ) (pressure and length) was studied in 30 dogs. The animals were divided in 3 groups: group 1, 10 dogs submitted to PCV with gastric ...
Glucose metabolism in rats submitted to skeletal muscle denervation
(Brazilian Archives of Biology and Technology, 2005-07-01)
O estudo analisou os efeitos locais e sistêmicos da imobilização por desnervação do músculo esquelético sobre o metabolismo glicidico. Ratos foram submetidos à secção do nervo ciático da pata direita. Observou-se redução ...
Morphologic alterations resulting from denervation of the diaphragm in rats
(Soc Chilena Anatomia, 2012-01-01)
The morphological alterations that occur in the muscle fibers of denervated rat diaphragms were studied. Fifteen adult male albino rats (Rattus norvegicus) with a mean weight of 200 g and about 60 days of age were used. ...
Down-regulation of Na+/K+-ATPase alpha(2) isoform in denervated rat vas deferens
(Elsevier B.V., 2000-09-15)
In the rat vas deferens, an organ richly innervated by peripheral sympathetic neurons, we have demonstrated recently the expression of alpha(1) and alpha(2), but not alpha(3) isoforms of the a subunit of Na+/K+-ATPase (EC ...
Myenteric denervation in gastric carcinogenesis: Differential modulation of nitric oxide and annexin-A1
(2013-01-01)
This study evaluated the properties of endogenous nitric oxide synthases (NOS) and annexin-A1 (ANXA1) and determined how they can be exploited in the N-methyl-N-nitro-N-nitrosoguanidine (MNNG)-induced gastric carcinogenesis ...
Differential distribution of some extracellular matrix fibers in an experimentally denervated rat megaileum
(Pergamon-Elsevier B.V. Ltd, 2008-06-01)
Absence of enteric neurons is associated with thickening of the intestinal muscularis externa in Chagas' disease. The thickening is due to hyperplasia and hypertrophy of the smooth muscle cells and increased extracellular ...
