Mdr1 express product p - glycoprotein was detected by immunocytochemical method and flowcytometry. the cytotoxicity and multidrug resistance reversion effect of tea polyphenol was examined by mtt assay in mcf - 7 and mcf - 7 adr carcinoma cell lines, and compared with pgp inhibitor quinidine. the pgp expression of mcf - 7 adr was strongly positive, the positive rate was 15 % ; the pgp expression of mcf - 7 was negative, the positive rate was 1. 8 %. ic50 of tea polyphenol to mcf - 7 and mcf - 7 adr is 115. 2g ml and 207. 6g ml respectively. ic50 of quinidine to mcf - 7 and mcf - 7 adr is 129. 8mol l 42. 1g ml and 94. 1mol l 30. 5g ml respectively. tea polyphenol and quinidine changed little toxicity of adriamycin to mcf - 7, but tea polyphenol and quinidine improved the sensitivity of mcf - 7adr to adriamycin significantly. immunocytochemistry and flow cytometry can detect p - glycoprotein expression level qualitatively and quantitatively. tea polyphenol is not only an anti - tumor agent, but also a multidrug resistant modulator similar as quinidine. tea polyphenol is advantageous for its little toxicity in tumor treatment
