[Research progress in the reversion of traditional Chinese medicine on multidrug resistance of tumor].

Researches on MDR (multidrug resistance) of tumor presently focus on seeking chemosensitizers with more targets, high efficiency and low toxicity from traditional Chinese medicine. This paper reviews the research progress in the reversion of MDR of leukemia, hepatocarcinoma, breast carcinoma and oral epithelioid neoplasia by TDM compound, its extracts, its groups of active ingredients or its active ingredients.
