1 RESULTS: In rats alveolar macrophages, (i) dantrolene (1 to 100 microM) caused a dose-dependent suppression of the production of nitrite and TNF-alpha induced by LPS (1 microgram.ml-1) plus IFN-gamma (100 u.ml-1) and (ii) dantrolene (100 microM) inhibited the activity (by 37 +/- 5%, P < 0.01) and protein expression (by 39 +/- 12%, P < 0.01) of iNOS in response to LPS plus IFN-gamma.

2 CONCLUSION: Dantrolene inhibits NO production as well as the activity and expression of iNOS in alveolar macrophages treated with LPS plus IFN-gamma, which may be associated with the reduction of TNF-alpha production. Dantrolene nitric oxide synthase 2 Rattus norvegicus
