The cytotoxicity of these compounds were valuated by MTT and SRB methods using three cancer cell lines: HL-60, A-549, P-388. Cyclo-shikonin, and cyclo-alkannin have high cytotoxicity against HL-60.The chiral center of side chain has no effect on their activity. 2- 1-(Acetyloxy-4-methyl-3-pentenyl -5, 8-dihydroxy-1, 4-naphthoquinone (105) has strong inhibition effect on P-388 cells. 2- 1-(isooctyloxy-4-methyl-3-pentenyl -5, 8-dihydroxy-1, 4-naphthoquinone (108) and 2- 1-(2-furoyloxy-4-methyl-3-pentenyl -5, 8-dihydroxy-1, 4-naphthoquinone (112) have high inhibition on A-549.Shikonin (1), alkannin (2), and their derivatives have the structural features of a planar chromophores and short side chain. We examined the ability to inhibit the telomerase.

白血病组骨髓细胞S%明显低于对照组。3例接受治疗的急性淋巴细胞性白血病患儿达到完全缓解后，其S%明显高于治疗前，非白血病组的骨髓细胞周期与正常对照组差异无显著性。

Methods Flow cytometry and CD45/Side scatter gating were used to have immunophenotyping of children's acute leucocythemia tested and to analyze antigenic expressions in 67 cases of children's acute leukemia.

方法选择67例儿童急性白血病，采用CD45/SSC双参数散点图设门法流式细胞术进行急性白血病免疫表型检测，分析儿童急性白血病细胞的抗原表达规律。

DESIGN, TIME AND SETTING: In vitro cytology experiment was performed at the laboratory of Department of Pediatrics, First Affiliated Hospital of Guangzhou Medical College from December 2007 to August 2008. MATERIALS: MSCs were provided by 30 leukemia children admitted to First Affiliated Hospital of Guangzhou Medical College, including 22 acute lymphoblastic leukemia and 8 acute myeloblastic leukemia.

Methods P-gp expression in 151 acute myeloblastic leukemia and 47 acute lymphoblastic leukemia was determined by monoclonal antibody UIC2 and flow cytometry. Results The rate of complete remission differred between P-gp+ and P-gp?

采用流式细胞术及单克隆抗体UIC2检测了151例成人急性髓细胞白血病、47例成人急性淋巴细胞白血病患者的白血病细胞P-gp表达。

Methods Compounds were isolated and purified by various column chromatographic techniques and their structures were elucidated on the basis of spectral analysis (IR, ESIMS, 1HNMR, 13CNMR). The inhibitory activity against the proliferation of HL60, REH and Raji cell lines was determined by using MTT assay.

In Chapter Two, some methods such as electron microscope, DNA ending label and MTT measurement were used to studied the changes of apoptosis, necroses and cell vigour of leukaemia K562 cell trunk and HL-60 cell trunk irradiated with millimeter wave. Different effects of millimeter wave to leukaemia cell trunks and human marrow cells were observed clearly. Human marrow cells were not so sensitive to millimeter wave radiation as leukaemia cells.
