Abstract
Using Fura-2AM microfluorimetry, we have shown for the first time that 5-lipoxygenase specific inhibitor antiasthmatic agent zileuton significantly inhibits Ca(2+)-responses induced by glutoxim and molixan in macrophages. The results support 5-lipoxygenase involvement in the effect of glutoxim and molixan on intracellular Ca(2+) concentration in macrophages and indicate the inadvisability of a combined use of drugs glutoxim and molixan and antiasthmatic agent zileuton.
