白血病的

The theory is cell kinetics and mechanism of drugs.

主要是根据细胞动力学原理和药物的作用机理分析，如果把药物集中应用，一方面只是一过性的杀灭增殖期的白血病细胞，对静止期细胞影响不大，另一方面对正常细胞造成较大损伤，而如果药物作用于几个细胞增殖周期，对白血病细胞进行几个循环的打击，会清除更多白血病细胞，而对正常细胞损伤较小。

Objective In order to explore the expression of the SH2 domain containing inositol 5′-phosphatase gene pro-oncogene and its impact on the prognosis in the patients with acute leukemia.

In this study, we found out that linalool, a small-molecule compound, could inhibit the growth of various human lymphocyte leukemia cell lines significantly. Meanwhile, it showed little toxicity to normal hematopoietic cells. To determine effects of linalool on the growth of a serious of human leukemia cell lines and normal hematopoietic cells and to explore its possible mechanisms, we employed various technologies, including MTT assay, Flow cytometry, Human Cancer PathwayFinder II Gene Array, Western Blot, RT-PCR and so on.

Expression of mutant tumor suppressor gene p53 in egg-type chicken with avian leukosis subgroup J was detected to study cancericidally molecular mechanism of ALV-J. Using immunohistochemistry method of strep avidin-biotin complex, many organs of illed egg-type chickens, involved liver, kidney, ventriculus glandularis, tumor, heart, pancreas, bone marrow, spleen, oviduct, lung, duodenum, thymus and bursa of fabricius were studied.

为了探讨J亚群禽白血病病毒的致癌分子机理，观察蛋用型鸡发生J亚群禽白血病时p53抑癌基因在各脏器中的表达，应用链霉亲和素-生物素-过氧化物酶复合物免疫组化法，研究了蛋用型鸡J亚群禽白血病自然病例的肝脏、肾脏、腺胃、肿瘤、输卵管、心脏、胰脏、骨髓、脾脏、肺脏、十二指肠、胸腺和法氏囊。

The cancers studied here were throat cancer, aute non- lymphoblas He leukem ia and acut lymphoblastic leukemia. The result s indicated that,(1)the levels of Leu, Lys, Ser Asn,Ile,Gly,and Thr were obviously decreased whea lse the levels of orn, Trp evidently increased in cultural liquid of throat can cer cell line indicating that the growth of HepⅡ cell consumed 7 amino acids and releaced 2 amino acids into cultural liquid.(2)the levels of Glu, Gls, Leu, Phe, Tyr and Trp were evidently increased while the levels of Thr , His, Ala decreased in plasma from patient with ANLL. These r esults were consistent with the previous report.(3)the levels of Gly, Trp and Phe in plasma from patients with ANLL evidently de creased and the levels of Ala, His increased after therapy indicating that cance r cells were growing in an anaerobic catabolism state.

这些癌肿包括喉癌HepⅡ细胞，急性非淋巴细胞白血病和急性淋巴细胞白血病，结果表明：(1)喉癌细胞株培养过程中亮氨酸、赖氨酸、丝氨酸、天冬酰胺、异亮氨酸、甘氨酸以及苏氨酸等水平明显降低，而色氨酸水平明显增加，说明喉癌细胞的生长繁殖必须依赖以上7种氨基酸同时释放了色氨酸；(2)急性非淋巴细胞白血病患者血浆中的谷氨酸、甘氨酸、亮氨酸、苯丙氨酸、酪氨酸和色氨酸等水平明显升高，而苏氨酸、组氨酸、丙氨酸等水平明显降低，这些结果与国际报道相一致；(3)经治疗后，ANLL患者血浆中甘氨酸、色氨酸和苯丙氨酸等水平明显降低，而丙氨酸、组氨酸等水平明显升高，表明肿瘤细胞处在无氧代谢。

SHI-1 cells can be engrafted in the pretreated nu/nu mice, and this model provides a useful experimental system for the research of leukemic extramedullary infiltration.

人单核细胞白血病细胞株SHI-1能在经SCI预处理的裸鼠体内形成白血病及多器官浸润模型，可作为研究白血病及髓外浸润的一种有用工具。

College of Animal Science and Veterinary Medicine,Shandong Agricultural University, Taian,Shandong , 271018, China Abstract:Avian leukosis virus Subgroup J is a retrovirus that infects meat-type chickens.

J亚群禽白血病病毒（Subgroup J of Avian leukosis virus，ALV-J）是90年代初由英国鉴定出来的禽白血病病毒新的亚群，主要引起肉鸡的骨髓瘤白血病。

Methods Between January 2001 to November 2003, 183 cases of acute leukemia were observation, 74 cases are acute lymphoblastic leukemia; 109 cases are acute myeloblastic leukemia.

分析我院 1996年 1月～ 2 0 0 3年 11月间收治的 183例初发白血病病人的资料，其中急性淋巴细胞白血病 74例，急性非淋巴细胞白血病 10 9例。

Specific siRNA was used to target LMO2 in Molt-4 cells. Results Higher expression of LMO2 was detected in some of patients with acute myeloblastic leukemia or acute lymphoblastic leukemia. However, enforced expression of LMO2 in K562 cells decreased cellular clonogenecity, suggesting the activation of the gene may not be important in the pathogenesis of myeloid leukemia.

结果 LMO2基因在很多急性髓系和淋巴系白血病患者的表达水平高于慢性白血病患者及正常骨髓细胞，但LMO2转染的K562细胞克隆形成率下降，提示该基因在髓系白血病细胞的表达异常是一种伴随结果而不具有致癌作用。

That of the other 6cases were unchanged and appeared serious clinical manifestations.All of these 6 patients died of sepsis finally.Above results suggestedthat immune response of leukaemic patients to MSHA ...

上述结果提示白血病病人对疫苗的免疫应答反应，在白血病缓解中起着重要作用，对临床早期准确判断白血病患者的预后很有意义。
