Lysozyme in Schwartz and Moloney virus-induced lymphoblastic leukaemia

Studies have been made on lysozyme in serum and tissue homogenates in normal and leukaemic mice. An increase in serum lysozyme level occurred in mice bearing both strains of leukaemia as compared to the normal counterparts. Moreover, the elevated enzyme levels seem to be related to the rise in neutrophils in peripheral blood. In the spleen and kidney of leukaemic mice, the lysozyme level was found to be lower than in the normals, while the enzyme level remained more or less unaltered in the liver. The findings are discussed in relation to other reports in the literature.
