H. Kroger et al., ENHANCEMENT OF THE EFFECT OF METHOTREXATE ON COLLAGEN II INDUCED ARTHRITIS IN MICE BY NICOTINAMIDE, Inflammation, 22(3), 1998, pp. 277-285
Treatment with a combination of 10 mg/kg i.p. methotrexate and 100 mg/
kg i.p. nicotinamide inhibits the development of collagen II induced a
rthritis in male DBA/1 X B.10(4R) mice, as assessed by the arthritic i
ndex and whole blood chemiluminescence. The effect is much more pronou
nced than with either methotrexate or nicotinamide alone at the same c
oncentrations. Determination of GOT and GPT levels in the blood reveal
ed that the treatment causes no toxic side effects on the liver.
