摘要

目的:mdr1基因转染的骨髓造血细胞自体移植后

观察VX2肝癌兔超剂量化疗中mdr1基因的骨髓保护及肿瘤治疗作用;并观测超剂量化疗对心脏的毒副作用。方法:mdr1基因转入兔骨髓单个核细胞并自体移植;阿霉素化疗

观测外周血白细胞数、VX2肝肿瘤的生长及转移、心脏结构和功能变化

评价mdr1基因对受体骨髓的保护作用、超剂量化疗对肿瘤的治疗作用及对心脏的毒副作用。结果:通过转染的自体骨髓移植将mdr1基因导入受体骨髓;超剂量阿霉素化疗后

实验组荷瘤兔外周血白细胞可维持在（4.26±1.03）×109/L

肿瘤能被有效杀灭

荷瘤动物的生存时间明显高于对照组（P<0.05）;同时也观察到超剂量化疗对心脏的严重损害。结论:mdr1基因能明显提高骨髓对化疗的耐受性;超剂量化疗能有效杀灭肿瘤

同时也对非造血系统脏器造成严重损害。

Abstract

Objective:In the study

multidrug resistance gene 1(mdr1) was transferred into the bone marrow mononuclear cells which were autotransplanted into rabbits with VX2 hepatocarcinoma.In chemotherapy experiment with adriamycin

the bone marrow protection of mdr1 gene

curative effects and side effects to heart of over dosage chemotherapy were observed.Methods: The bone marrow mononuclear cells transferred with mdr1 gene were autotransplanted into rabbits with VX2 hepatocarcinoma.After chemotherapy with adriamycin

the peripheral white blood cells count

the growth and metastasis of VX2 hepatocarcinoma and cardiac function were detected.Meanwhile

the bone marrow protection of mdr1 gene

the curative effects to VX2 hepatocarcinoma and lesions to heart of over-dosage chemotherapy were evaluated.Results:The mdr1 gene was implanted into the bone marrow after the mdr1-transferred bone marrow mononuclear cells had been autotransplanted into rabbits with VX2 hepatocarcinoma.After over-dose chemotherapy with adriamycin

the rabbits in mdr1-transferring group could be survival after treated with 3-fold dosage chemotherapy

and the white blood cell count in peripheral blood was(4.26±1.03)×109/L.Meanwhile

the tumor cells were killed effectively

and the survival time were improved compare to that of control group(P<0.05).However

the severe lesions to heart caused by over dosage chemotherapy were observed.Conclusions: The bone marrow of the receptor could be protected from toxic effects of chemotherapy after transplantation of bone marrow mononuclear cells transferred with mdr1 gene

and the malignant tumor cells could be killed effectively and severe lesions to non-hematopoietic systems were caused by over dosage chemotherapy.
