title: Effect of prostaglandin E2 on plasma lactic dehydrogenase activity in (NZB x NZW)F1 mice with a chronic infection of lactic dehydrogenase virus.
abstract: The effect of prostaglandin E2(PGE2) on blood LDH values was investigated in (NZB x NZW)F1 mice with or without an established infection with lactic dehydrogenase virus (LDV). Plasma LDH decreased in infected mice treated with PGE2, but increased in infected mice treated with indomethacin, an inhibitor of PGE2. However no significant effect on LDH occurred in uninfected mice treated with PGE2 or indomethacin. To investigate the mechanisms of decreased LDH activities resulting from treatment with PGE2, clearance tests were performed. Clearance of LDH-5, but not LDH-1, was faster in PGE2-treated mice than in non-treated mice, whether or not they were infected with LDV. The results suggest that enhanced clearance of LDH-5 in mice treated with PGE2 may account for the fall in plasma LDH in LDV-infected mice.
