Effect of levamisole on cell sensitivity in rats with experimental Heymann's nephritis.
The development of cell-sensitization to renal antigen in rats with experimental Heymann's glomerulonephritis and the effect of levamisole on cell sensitivity have been studied. Morphologic changes in GN rats appeared after 14 days and were most pronounced on days 21-28, with focal proliferation of glomerular cells, an increase of mesangium, a focal increase of the basal membrane material. After day 49 the changes improved slightly and were still the same on day 147 when a location of IgG to the glomerular basal membrane was detected. In every GN rat, cell-sensitivity to renal antigen was revealed from day 21 of the experiment till its end. Levamisole treatment decreased renal morphologic changes and abolished cell-sensitivity to renal antigen. The possible mechanisms of preventing the development of cell-sensitization in rats treated with levamisole are discussed.
