The endogenous cannabinoid agonist, anandamide produced a modest contractile response in guinea-pig isolated bronchus compared with the vanilloid receptor agonist capsaicin. The contractile response to both anandamide and capsaicin was inhibited by the vanilloid receptor antagonist, capsazepine. Furthermore, the NK(2)-selective antagonist, SR48968 but not(More)
1. There is considerable interest in elucidating potential endogenously derived agonists of the vanilloid receptor and the role of anandamide in this regard has received considerable attention. In the present study, we have used an electrophysiological technique to investigate the mechanism of activation of vanilloid receptors in an isolated vagal(More)
Study objective. Th2 cytokines play an important role in the pathogenesis of asthma. Our study objective was to determine the effect of suplatast tosilate, a Th2 cytokine inhibitor, on patients with cough-variant asthma. Methods. Twenty patients with cough-variant asthma (CVA) were assigned to a suplatast tosilate (100 mg three times daily) group or a(More)
Docosahexaenoic acid (DHA) is an essential nutrient for human health, but has extremely high oxidative susceptibility. We examined the suppressing effect of sesamin, a sesame seed lignan, on lipidperoxides in rats fed a low alpha-tocopherol and high DHA containing diet. Groups of rats were fed four experimental diets: low alpha-tocopherol (10 mg/kg diet)(More)
Chronic cough is the only symptom of eosinophilic bronchitis (EB). There is considerable overlap between EB and atopic cough. To investigate the antitussive effects of a histamine H1-recetor antagonist, epinastine hydrochloride (epinastine, CAS 80012-43-7, Alesion; 20 mg/day, once daily), cough scores, pulmonary function, capsaicin cough threshold, and(More)
Few cases of Mycoplasma pneumoniae and Chlamydia pneumoniae coinfection in pneumonia have been reported in adults. We report a case of such a double infection in a young adult. A 16-year-old boy was admitted to our hospital with dry cough and fever. Laboratory findings revealed elevated serum GOT and GPT levels. The patient had been administered a(More)
Objective: We studied the bronchodilatory effect of tiquizium bromide [3-(di-2-thienylmethylene)-5-methyl-trans-quinolizidinium bromide; TQZ], an antimuscarinic agent, on airway smooth muscle in vitro, and also in patients with chronic obstructive pulmonary disease (COPD). Methods: In the first experiment, canine tracheal smooth muscle was used to measure(More)
