title: Action of mannitol in various immunological experimental models.
abstract: The authors describe the inhibiting action of mannitol after repeated administration of low subcutaneous doses in a number of experimental immunological models. For example, in the rat it produces a reduction of the secondary arthritis of Freund's adjuvant polyarthritis and also of the pleurisy due to Bordetella pertussis hypersensitivity. In the mouse it reduces the reaction of delayed hypersensitivity to sheep red cells. Its action is also marked against ovalbumin-induced active skin anaphylaxis in the albino guinea-pig and on IgE synthesis in the rat. Moreover, after several injections it produces a reduction of carbon phagocytosis in the mouse. At the doses at which the effect appeared, no action could be found on various models of acute non-immune inflammation, diuresis, blood pressure, hematocrit and protein and plasma sodium levels.
