Study on the relationship between expression of p-glycoprotion in peripheral blood mononuclear cell and multidrug resistance of patients with cancer
the detection of multidrug resistance depends on resected specimen but it can not be investigated in patients who were not operated on or got a long term chemotherapeutic treatment after operation. In this study
the relationship between p-glycoprotein expression in PBMC,CD 4+,CD8+ and tumor cells has been investigated. In order to obtain a new determination method for multidrug resistance
the changes of p-glycoprotein expression in PBMC,CD 4+,CD 8+ during chemotherapeutic stage has been analysed. Methods: The expression of p-glycoprotein in PBMC,CD 4+,CD8+ and tumor cells has been detected by means of immunohistochemestry assay in 23 cases
flow cytometry and immunohistochemestry assay in 28 cases to identify the relationship of p-glycoprotein between PBMC,CD 4+,CD8+ and tumor cells. P-glycoprotein in PBMC,CD 4+ and CD8+ was measured in 17 of 28 patients with chemotherapeutic treatment for six months. Results: ①The p-glycoprotein expression in PBMC,CD4+,CD8+ of patient with malignant tumor was higher than the control. ②A significance relationship of p-glycoprotein had been found between PBMC,CD 4+,CD8+ and tumor cells. ③ The p-glycoprotein expression in PBMC,CD 4+,CD 8+ increased significantly in chemotherapeutic group as compared with non-chemotherapeutic group. ④Flow cytometry assay was more sensitive than immunohistochemestry in detecting p-glycoprotein expression in PBMC,CD 4+,CD8+ . Conclusion:The detection of p-glycoprotein in PBMC,CD 4+,CD8+ provides a new method in the MDR determination. A relationship of p-glycoprotein has been found between PBMC,CD 4+,CD8+ and tumor cells.
