The Opsonic Action of Serum

[摘要] It has been shown by Gordon, Whitehead and Wormall (1) that ammonia-treated serum, in which the complement is entirely inactivated through destruction of the fourth component, is nevertheless still able to opsonise staphylococci. This fact indicates that the whole complement system is not necessary for opsonic action, a view supported by further data described by Gordon, Whitehead and Wormall (2), Gordon (3) and Gordon and Thompson (4).Recently Maltaner (5) has shown that a suspension of leucocytes, either unheated, or heated at 55°C. for ½ hour, can supply fourth component to ammonia-treated serum, and that in this respect the heated suspension is actually more active than the unheated. The suspension of leucocytes acts in conjunction with the ammonia-treated serum in the same way as heated normal serum has been shown to do.
