title: [Lactoferrin in human lung tumors].
abstract: Immunodiffusion technique was used to study the lactoferrin (LF) distribution in human fetal, normal and tumour tissue extracts. If was found that LF concentration in lung tumour extracts was higher than in normal lung one. Indirect immunoperoxidase method revealed LF in alveolar macrophages of normal and tumour lung tissues, in afflux of these cells around the tumour cells, but never--in the original lung cancer cells. It is suggested that LF is not a lung tumour-associated antigen.
