Inflammation and enhanced nociceptive responses to bladder distension produced by intravesical zymosan in the rat
BACKGROUND Mycotic infections of the bladder produce pain and inflammatory changes. The present study examined the inflammatory and nociceptive effects of the yeast cell wall component, zymosan, when administered into the urinary bladder in order to characterize this form of bladder sensitization. METHODS Parametric analyses of the time-course (0-48 hr) and concentration (0-2% solutions) vari...
متن کاملResponses 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 کاملTENS attenuates response to colon distension in paraplegic and quadriplegic rats.
Individuals with spinal cord injuries above thoracic level 6 experience episodic bouts of life-threatening hypertension as part of a condition termed autonomic dysreflexia (AD). The hypertension can be caused by stimulation of the skin, distension of the urinary bladder or colon, and/or muscle spasms. Transcutaneous electrical nerve stimulation (TENS) may reduce the severity of AD because TENS ...
متن کاملSympathetic and cardiovascular responses to venous distension in an occluded limb.
We recently showed that a fixed volume (i.e., 40 ml) of saline infused into the venous circulation of an arterially occluded vascular bed increases muscle sympathetic nerve activity (MSNA) and blood pressure. In the present report, we hypothesized that the volume and rate of infusion would influence the magnitude of the sympathetic response. Blood pressure, heart rate, and MSNA were assessed in...
متن کاملEsophageal responses to distension and electrical stimulation.
The opossum esophagus contains only smooth muscle in the distal two-thirds; it can be used to study autonomic control of esophageal smooth muscle. Three different preparations of opossum esophagus were used; the esophagus in vivo, the isolated whole esophagus, and isolated strips of the three layers of esophageal smooth muscle. Responses were examined to localized distension and to electrical s...
