Responses to gastric distension in functional dyspepsia.
BACKGROUND Studies have shown that an altered visceral perception threshold plays a role in the pathogenesis of upper gastrointestinal tract symptoms in dyspeptic patients. However, it is not clear whether the compliance and adaptive relaxation of the proximal stomach contribute to the symptoms. AIMS To investigate whether abnormal relaxation or adaptation of the proximal stomach during the i...
متن کاملGastric wall ischemia following massive gastric distension due to peptic pyloric stenosis: a case report
Gastric necrosis is a rare entity mainly due to the rich collateral blood flow the stomach is supplied by. Acute gastric dilation is one of the described underlying causes, and although not fully understood, many potential alterations, such as vascular compression, herniation, volvulus, acute necrotizing gastritis, complications after abdominal surgery, anorexia, bulimia nervosa, trauma, exposu...
متن کاملTNF-alpha activates solitary nucleus neurons responsive to gastric distension.
Tumor necrosis factor-alpha (TNF-alpha) is liberated as part of the immune response to antigenic challenge, carcinogenesis, and radiation therapy. Previous studies have implicated elevated circulating levels of this cytokine in the gastric hypomotility associated with these disease states. Our earlier studies suggest that a site of action of TNF-alpha may be within the medullary dorsal vagal co...
متن کاملPseudoaffective cardioautonomic responses to gastric distension in rats.
We examined the heart rate response to gastric distension, the involvement of vagal and sympathetic sensory afferents, adrenergic and cholinergic neural pathways, and the effects of capsaicin on this response in anesthetized rats. Gastric distension volume dependently decreased heart rate by 24.5% (resting rate = 219.87 ± 14.06 beats/min, mean rate during gastric distension with 15 ml = 165.97 ...
متن کاملParametric analysis of gastric distension responses in the parabrachial nucleus.
The parabrachial nucleus (PBN) is regarded as an important locus for the processing and integration of sensory inputs from oral, gastrointestinal, and postabsorptive receptor sites and is thus thought to play an important role in regulating food intake. Gastric distension is an important satiation cue; however, such responses have been qualitatively characterized only over a limited area of the...
