The effect of methotrexate on lipoxygenase metabolism in neutrophils from rats:In vitro andex vivo studies

Studies were undertaken to examine the effect of methotrexate (MTX) administeredin vivo or addedin vitro upon the production of the 5-lipoxygenase (5-LO) metabolites of arachidonic acid (AA) by rat neutrophils. Peptone-induced peritoneal exudate cells were stimulated by A23187 and the cell suspensions assayed for leukotriene B4 (LTB4), the all-trans isomers… CONTINUE READING
