Models of Visceral Nociception.
Pains arising from the viscera constitute a large portion of clinically treated pains. They are characterized by poor localization; immobility with tonic increases in muscle tone; and vigorous but nonspecific changes in autonomic function, such as changes in respiration, heart rate, and blood pressure. Tissue-damaging stimuli do not reliably produce visceral pain, so the study of visceral nocic...
متن کاملNeuroanatomy of visceral nociception: vagal and splanchnic afferent.
Afferent fibres convey sensory information from the upper gastrointestinal tract to the central nervous system but the nature of this information is different for vagal and spinal pathways. Vagal afferents convey predominantly physiological information while spinal afferents are able to encode noxious events. Because of the different response profiles following activation of these pathways, it ...
متن کاملCentral effect of histamine on acetic acid-induced visceral nociception in rats
In the present study, the effects of intracerebroventricular (ICV) injections of histamine, chlorpheniramine (H1-receptor antagonist) and ranitidine (H2-receptor antagonist) were investigated on visceral nociception induced by an intraperitoneal (IP) injection of acetic acid in rats. The latency time to the beginning of the first abdominal wall contraction (the first writhe) was recorded and th...
متن کاملEstrogen and Visceral Nociception at the Level of Primary Sensory Neurons
Clinical studies suggest the comorbidity of functional pain syndromes such as irritable bowel syndrome, painful bladder syndrome, chronic pelvic pain, and somatoform disorders approaches 40% to 60%. The incidence of episodic or persistent visceral pain associated with these "functional" disorders is two to three times higher in women than in men. One of the possible explanations for this phenom...
متن کاملInvolvement of NMDA and non-NMDA receptors in transmission of spinal visceral nociception in cat.
AIM To study the role of N-methyl-D-aspartic acid (NMDA) and non-NMDA receptors in processing nociceptive visceral information in the spinal cord. METHODS The firing of spinal dorsal horn neurons to colorectal distension (3-15 kPa, 20 s) by inflation with air of latex balloon was recorded in 25 anesthetized cats. RESULTS 1) According to the patterns of responses to colorectal distension, th...
