title: Laboratory investigations in Balkan endemic nephropathy.
abstract: Serum samples from three patients with Balkan endemic nephropathy (BEN) were inoculated intraperitoneally to guinea pigs. After a very long incubation period (58-273 days) the animals developed an experimental disease characterized by apathy, tremor, convulsions and a fatal outcome. The disease could be serially propagated, the same clinical symptoms being recorded at each of the three passages performed. The morphological features of the experimental disease included glomerular and tubular lesions and the presence of interstitial fibrous and lymphoplasmocytic reactions. Different hypotheses on the etiology of BEN are discussed.
