[The effect of the cationic proteins of human blood cells on the growth of Escherichia coli].
The antibacterial effect of cationic proteins (CP) on donor leukocytes and thrombocytes with respect to the growth of E. coli has been demonstrated in vitro, the maximum recorded inhibition being caused by the action of leukocytic CP. Differences in the inhibitory action may be linked with the presence of anomalies in the amino acid composition of leukocytic CP and thrombocytic CP, manifested by the deterioration of the basic properties of the latter, as well as by the fractional composition whose characteristic features for thrombocytic CP are the appearance of high-molecular components and a decrease in the proportion of low-molecular fractions. In patients with different forms of leukosis (chronic myeloleukemia, chronic lympholeukemia, acute myelomonoblastic leukosis) leukocytic CP retain their antibacterial activity. Under the action of blood cell CP changes in the outer and cytoplasmic membranes have been noted.
