Several lines of evidence have shown a role for the nitric oxide/cyclic guanosine monophosphate signaling pathway in the development of spinal hyperalgesia. However, the roles of effectors for cyclic guanosine monophosphate are not fully understood in the processing of pain in the spinal cord. The present study showed that cyclic guanosine(More)
Ozone is an environmental pollutant with potent oxidizing properties. We investigated whether exposure to ozone-induced cell proliferation in the lungs of rats, and determined the effect of an antioxidant and of a glucocorticosteroid in Brown-Norway (BN) rats. Following single ozone exposure (0.5, 1.0, or 3.0 ppm for 6 h), proliferating cell nuclear antigen(More)
Bradykinin (BK) is a peptide mediator generated at sites of inflammation and its effects are mediated through constitutively expressed B 2 receptor or through induction of B 1 receptors. We examined the role of these receptors in bronchial hyperresponsiveness (BHR). Brown-Norway rats sensitized with ovalbumin (OA) and Al(OH) 3 intraperitoneally, were(More)
1. Muscarinic receptor subtypes mediating neurogenic mucus secretion in ferret trachea were characterized in vitro and in vivo using 35SO4 as a label for secreted mucus, and the muscarinic receptor antagonists telenzepine for the M1 receptor subtype, methoctramine for the M2 subtype and 4-diphenylacetoxy-N-methylpiperidine methobromide (4-DAMP) for the M3(More)
Ciclesonide is a novel, inhaled corticosteroid under development for the treatment of asthma. Ciclesonide is activated to desisobutyryl-ciclesonide (des-CIC) in the lungs to provide potent anti-inflammatory activity. The investigations herein compared the activity of ciclesonide with fluticasone in animal models to assess efficacy/potency as an airway(More)
Based on the partial efficacy of the HIV/AIDS Thai trial (RV144) with a canarypox vector prime and protein boost, attenuated poxvirus recombinants expressing HIV-1 antigens are increasingly sought as vaccine candidates against HIV/AIDS. Here we describe using systems analysis the biological and immunological characteristics of the attenuated vaccinia virus(More)
We investigated the ability of the cannabinoid agonists CP55,940 (CB(1)/CB(2)) and anandamide (endogenous cannabinoid) to modulate electrical field stimulation (EFS)-induced acetylcholine (ACh) release from parasympathetic nerve terminals innervating guinea-pig trachea. We assessed whether modulation of transmitter release translated to an impact on(More)
