Chemiluminescence response and arachidonic acid metabolism of macrophages induced by gamma-hexachlorocyclohexane (lindane).
The influence of gamma-hexachlorocyclohexane (gamma-HCCH) on arachidonic acid (AA) metabolism and oxygen metabolite production was investigated on mouse peritoneal macrophages gamma-HCCH stimulated 6KPGF1 alpha, PGE2, LTC4, LTB4 and HETEs production and increased the luminol-dependent chemiluminescence (CL). Lindane acted synergistically with phorbol ester on prostaglandins-leukotrienes (PGs-LTs) and CL production. Similar stimulation of CL and PGs-LTs production was found after challenge by the calcium ionophore A23187. The implication of calcium mobilization in lindane effects was proposed.
