Experimental inflammation produced by an intraplantar injection of complete Freund's adjuvant results in local sensory hypersensitivity and up-regulates the neuropeptides substance P and calcitonin gene related peptide in the primary sensory neurons innervating the inflamed tissue. The inflammation also elevates nerve growth factor levels in the skin.(More)
An overlap between subpopulations of nerve growth factor (NGF)-responsive and capsaicin-sensitive dorsal root ganglion (DRG) sensory neurons has been suggested from a number of in vivo studies. To examine this apparent link in more detail, we compared the effects of capsaicin on adult rat DRG neurons cultured in the presence or absence of NGF. Capsaicin(More)
In contrast to developing sensory neurons, the survival of adult rat dorsal root ganglion neurons in pure neuronal culture is not dependent on specific neurotrophic factors such as nerve growth factor or brain-derived neurotrophic factor [Lindsay R. M. (1988) J. Neurosci. 8, 2394-2405]. In the present study we have examined possible modulatory effects of(More)
Inflammation results in a local increase in nerve growth factor production which potentially can modify the properties of nerve growth factor-responsive sensory neurons innervating the inflamed tissue. The sensitivity of primary sensory neurons to the neurotoxin capsaicin is regulated in vitro by nerve growth factor and we have now investigated the effect(More)
The expression of growth-associated protein GAP-43 mRNA in spinal cord and dorsal root ganglion (DRG) neurons has been studied using an enzyme linked in situ hybridization technique in neonatal and adult rats. High levels of GAP-43 mRNA are present at birth in the majority of spinal cord neurons and in all dorsal root ganglion cells. This persists until(More)
Adult dorsal root ganglion (DRG) cells are capable of neurite outgrowth in vivo and in vitro after axotomy. We have investigated, in cultured adult rat DRG cells, the relative influence of nerve growth factor (NGF) or a prior peripheral nerve lesion on the capacity of these neurons to produce neurites. Since there is evidence suggesting that the(More)
BACKGROUND It is possible that many deaths from pneumonia may involve the generation of inflammatory mediators and tissue damage by activated phagocytes. To test this hypothesis phagocyte function, plasma levels of interleukin 6 (IL-6), tumour necrosis factor alpha (TNF alpha), and soluble interleukin 2 receptor (IL-2R), disease severity, and outcome have(More)
BACKGROUND The aim of this study was to show that sequential intravenous and oral moxifloxacin monotherapy (400 mg once per day) is as efficacious and safe as a combination regimen (intravenous ceftriaxone, 2 g once per day, plus sequential intravenous and oral levofloxacin, 500 mg twice per day) in patients hospitalized with community-acquired pneumonia.(More)
BACKGROUND The aim of this study was to evaluate the effects of single and chronic dosing with salmeterol on exercise capacity and lung function in patients with chronic obstructive pulmonary disease. METHODS Twenty nine patients of mean (SE) age 64 (1.5) years, forced expiratory volume in one second (FEV1) 42(3)% of predicted, and 5-15% reversibility to(More)
Clostridium difficile infection (CDI) remains a major healthcare problem associated with antibiotic use in hospitals. Recent years have seen a dramatic increase in the incidence of CDI in the UK and internationally. Lower respiratory tract infections (LRTIs) are the leading indication for antibiotic prescription in hospitals and are therefore a critical(More)
