Abstract

CONTINUING our research on lysozymes from different origins1, we were interested in the purification of a human lysozyme. Some preliminary experiments have indicated that human placenta, saliva and spleen contain lysozymes, approximately 4, 10 and 40 mgm./kgm. respectively (quantities expressed in mgm. of hen's egg white lysozyme). In contrast with cow's milk, we have found that human milk contains a lysozyme (40 mgm./l. expressed in mgm. of hen's egg white lysozyme).
