title: Immunologic alterations in MRL/lpr mice after chronic dimethyl sulfoxide administration.
abstract: Dimethyl sulfoxide (DMSO) in 1 and 2% concentration was added to the drinking water of 30-100 day MRL/lpr mice. In comparison to control mice, the DMSO treated mice had a 78% increase in their response to exogenous IL-2 and a 64% increase in production of IL-2. Con A stimulated cells had a net help effect in the untreated mice, which was suppressed from 82-26% after DMSO treatment. There was no marked change in Thy 1.2, Lyt 1 and Lyt 2 percentages after treatment. The anti-DNA decreased from 29.0 +/- 17.0% to 13.2 +/- 7.8% after DMSO treatment. We conclude that chronic DMSO administration to MRL/lpr mice can induce immunologic alterations with possible clinical implications.
