中药拮新康抗白血病细胞与免疫机能的研究   总被引:6,自引:1,他引:5  
采用中药制剂拮新就对34例白血病患者的白血病细胞进行体外细胞毒性试验,试验显示:长春新碱+拮新康组较长春新碱组细胞新毒性明显增加,其中20例为难治与复发白血病患者对长春新碱已耐药,但加拮新康后细胞毒性作用增强;同时拮新康本身对白血细胞也有一定的抗肿瘤作用。采用环磷酰胺抑制小鼠免疫机能作实验模型,探讨“拮新康”对小鼠细胞免疫机能的影响,发现其对免疫损伤动物模型及正常动物的IFNr与NK活性水平较对照  相似文献

高效液相色谱法测定人血浆中汉防己甲素   总被引:4,自引:0,他引:4  
The paper reports the determination of tetrandrine by high performance liquid chromatography (HPLC). A C18 column was used and the mobile phase was methanol-water(80:20) containing 0.03% triethylamine, detective wave was at 282 nm, the internal standard was diazepam, the sample was extracted with ether. The linear range was from 0.289 microgram.ml-1 to 4.618 micrograms.ml-1, the average recovery rate was 95.8%. The coefficients of variation of within-day and day-to-day were less than 5%. This method is simple, rapid and accurate. It can be used in biomedical sample analysis of tetrandrine.  相似文献

Rectal foreign bodies   总被引:2,自引:0,他引:2  
We review the histories of 26 patients who were treated at the Royal Perth Hospital for retained rectal foreign bodies. The foreign bodies that were retrieved and the age, sex and marital status of each patient are recorded and a number of the histories is presented. The complications that arose from either the insertion or removal of the foreign body are discussed, as are the methods of treatment that were employed. The various methods that the practitioner has at his disposal for dealing with this increasing problem are reviewed, and a plan of management of patients with non-perforating rectal foreign bodies is suggested.  相似文献

1.The results show that PIXE analysiscan be used advantageously in trace elementanalysis of biomedical samples.The normalvalues of trace elements in serum obtainedin our work agree with values reported byOther researchers.2.Changes of trace elements in serumwere found in“Yin-deficiency”aNd“Yang-deficiency”as diagnosed in traditional Chi-nese medicine.In addition to the significantdifferences of the concentration of Cu andthe ratio of Zn/Cu between“deficiencysyndrome”patients and normal SUbjects,there also appeared to be significant dif-ference between“Yin-deficiency”and“Yang-deficiency”patients.  相似文献
