To establish a protocol for analyzing NK cell cytotoxic activity (NKAc) in breast cancer patients using the flow cytometric technique. Methods: We first optimized the protocol based on the previously published studies, focusing on choosing fluorescent dye concentration, incubation time length, and Effector:Target cell ratio (E:T ratio). Subsequently, we preliminarily applied the established protocol to characterize NKAc in some breast cancer patients and healthy controls.

OECD guidelines were applied. Mice were divided into 7 groups consisting of 30 females and 10 males each. In which, the control group received the solvent, only females or males in 4 other groups were taken the testing samples (32), and both females and males of 2 remain groups were given those samples. Mice were given oral samples at a dose of 288 or 576 mg/kg/day × 7 consecutive days depending on individual group.
