Does hydrogen sulphide induce vasoconstriction of rat coronary artery via activation of Ca ( 2+ ) influx?
NaHS induces the contraction of rat coronary artery, which is dependent on the activation of Ca(2+) influx. Rho kinase likely participates in the vasoconstriction.
Our data suggest that clofazimine's delayed antimicrobial activity may be due more to its mechanism of action rather than to host-related factors.
