[Preliminary study on the effects induced by an anemic strain of Friend leukemia virus in DBA/2 mice]. / Studio preliminare sugli effetti indotti dal ceppo anemico del virus della leucemia di Friend in topi DBA/2.

Serum thymic factor (STF) and azathioprine (AZ) inhibition test were assayed in sera and spleen cells from DBA/2 and BALB/c mice, inoculated with the anemic strain of Friend leukemia virus. The observed decrease of STF levels appears to be related to the LLV (Lymphatic Leukemia Virus) component of FLV-A.
