Ukrain is an anticancer agent prepared from Chelidonium majus L. alkaloids. Its anticancer efficacy in vitro was showed on several human cell lines, in terms of GI₅₀, TGI, and LC₅₀ parameters, and directly on several patients. Besides its direct influence on cancer cells, the agent was found to influence the immune system of the patient under treatment. The present studies were undertaken to evaluate the influence of Ukrain on a population of natural killer (NK) cells.
