The anticonvulsant drug gabapentin has been demonstrated to alleviate symptoms of painful diabetic neuropathy as well as other types of neuropathic pain. The aim of the present study was to investigate the effect of gabapentin in a recently developed mouse model of peripheral neuropathy. This model is based on a photochemical ischemic lesion of the sciatic(More)
Numerous in vitro studies suggest that inflammation is associated with enhanced release of substance P (SP) in the dorsal horn. To test the hypothesis that inflammation increases the evoked concentration of SP in the intact animal, we used in vivo microdialysis with a highly sensitive radioimmunoassay to monitor SP-like immunoreactivity (SP-LI) in the(More)
Long-term potentiation (LTP) in wide dynamic range (WDR) neurons in the dorsal horn has been suggested to contribute to central sensitization and the development of chronic pain. Indirect experimental evidence indicates an involvement of substance P (SP), in this respect. The aim of the present study was to monitor the extracellular level of substance(More)
Secretion of parotid and submandibular saliva evoked by electrical stimulation of the parasympathetic nerves occurred in the presence of adrenergic and cholinergic blocking agents. The 'atropine-resistant' response amounted to about 30% in the submandibular gland and to about 5% in the parotid gland as compared to the response before administration of(More)
