title: Macrophage migration inhibition factor in pemphigus vulgaris.
abstract: Three cases of pemphigus vulgaris probably induced by ampicillin treatment are described. All of the patients' lymphocytes responded positively toward ampicillin in the migration inhibition factor test. There is a possibility that this test might be significant in recognizing the offending drug in vitro.
