[Assessment of immunity and allergy after vaccination with dry combined anthrax vaccine].

Study of humoral immune response and allergy in recipients of dry combined anthrax vaccine was performed. Immune response was assessed by antibody titers to protective antigen and by index of preventive properties of blood serum (PPS) of recipients. Relation of index of PPS and antibody titers in blood serum of the donors was established.

[Effect of cryoconservation of platelets on polyamine level and cathepsin D activity].

Alterations in activity of cathepsin D as well as in content of polyamines spermine, spermidine, x-fraction (apparently, acetyl spermidine) and putrescine were studied in blood platelets depending on conditions of conservation. The enzyme activity and content of polyamines correlated directly with duration of the cell concentrates storage. Cathepsin D and polyamines appear to be involved in responses to stress adaptation.
