[Effect of serum from patients with kerion celsi on organ culture of chick embryo skin].

In the present work the Authors have studied the differentiation and the cellular multiplication of chick embryo skin incubated in vitro with normal human sera or with pathological human sera from patients affected by Kerion Celsi. In the following research the Authors have studied the skin structure by an optical and electron microscope and the thymidine 3H incorporation. The result demonstrates that the pathological human serum does not interfere with the multiplication and the differentiation of the skin in vitro, but displays a cytoaggressive action that induces a noticeable cytoplasmic vacuolation.
