In the present study, we have used in situ hybridization to examine the distribution of serotonin (5-HT) receptors in rat dorsal root ganglion (DRG) neurons. Within DRG neurons, mRNAs for 5-HT1B, 5-HT1D, 5-HT2A, 5-HT2B, 5-HT3B and 5-HT4 receptors were readily detected in small (<25 microm), medium (25-45 microm) and large (>45 microm) diameter neurons.

Results were evaluated in 81 patients with suspected acute aortic dissection who were examined on a fast CT system capable of a 1 s data acquisition time. 17 patients had Type A and nine had Type B dissections. Radiological assessment provided 78 confident reports and expressed some uncertainty about the diagnosis in three patients. Overall sensitivity for(More)
An intensive programme of guideline development and dissemination is not always practical. We designed general practitioner guidelines for chest radiography and disseminated them to a group of 33 practices selected randomly from the practices that refer more than five patients for chest radiography annually. The subsequent 2500 requests were analysed and(More)
AIM To document the phenomenon and distribution of air-trapping on computed tomography in patients with sub-acute extrinsic allergic alveolitis (EAA). PATIENTS AND METHODS A retrospective analysis of high resolution CT scans was performed on 20 patients with proven EAA. All patients had inspiratory scans and 12 patients had expiratory scans. These were(More)

We present a case of trans-sphenoidal encephalomeningocele in association with a posterior cranial fossa malformation which fulfils the criteria for the Dandy-Walker complex [1]. Congenital cardiovascular defects were also present. An abnormality of neural crest development may be responsible for the combined occurrence of these anomalies.
Technetium-99m HMPAO labelled white cell scanning is now an accepted method for assessing the activity of inflammatory bowel disease. However, false positive results have been demonstrated. This study was conducted to assess the significance of low grade uptake on 99Tcm-HMPAO labelled white cell scans in the right iliac fossa (RIF) in the context of(More)
