Augmentation of mouse natural killer cell activity by a streptococcal preparation, OK-432.

Abstract

Streptococcal immunopotentiator OK-432 (NSC-B116209) augmented the natural killer (NK) cell activity of peritoneal exudate cells (PEC) in inbred C57BL/6 mice given ip injections of 0.1 mg OK-432 per mouse. The cytotoxic activity of PEC increased as early as 1 day after inoculation, reached its peak on day 3, and gradually declined thereafter, YAC-1, K562… (More)
