Summary Albino rabbits with experimental brain oedema produced by a combined left hemisphere cryogenic injury and a metabolic insult by a 6-aminonicotinamide (6-ANA) were administered intravenous dimethyl sulphoxide (DMSO) in varying concentrations and doses in the following manner: Subgroup A (concentration response) received 1.0 g/kg bolus of a 10, 20, 30, or 40% solution. Subgroup B (dose response) received as a 20% solution a 1.0 g/kg bolus, 1.5 g/kg bolus, or 2.0 g/kg infusion. One hour following administration of the agent, the animals were killed, their brains rapidly removed by craniectomy and brain water, sodium and potassium measured. Significant decreases in brain sodium and water content in the right hemisphere were noted in both subgroups A (p 〈 0.05) and B (p 〈 0.005) and in the left hemisphere in subgroup B only (p 〈 0.005). There is an apparent effect on brain oedema by a DMSO mediated sodium dependent water mobilization.
