The proliferation was determined by measuring -TdR incorporation in a β-scintillation counter. RESULTS: The in vivo administration of CCK-8 resulted in increase of B7.2 expression, but without any influence on B7.1 expression in peritoneal macrophages. CCK-8 also exhibited increased the -TdR incorporation in CD4(superscript +)T cells.

结果：整体应用CCK-8作用小鼠腹腔巨噬细胞，与对照组相比，CCK-8可上调静息小鼠腹腔巨噬细胞B7.2的表达，而对B7.1的表达则无影响；并且CCK-8使CD4T细胞[3H]-TdR的掺入率升高，即促进其增殖，增强巨噬细胞的协同刺激活性。

The optimal time for combination of radiosensitizers and radiotherapy will be determined from the significant difference of uptake and retention between the tumor and the major normal tissues. The biodistribution obtained from organ removal and counted by gamma scintillation counter was similar to that obtained from autoradiography.

本研究利用加马闪烁计数器与自动放射摄影术两种方法，探讨分别或同时使用[131I] IUdR、[18F] FMISO在肿瘤及正常器官的摄取状况、清除速率及生物分布，找出此两种药物在肿瘤中积聚最多的时间点，并与其他正常器官有明显的差别，以期应用在临床上病人给药的依据。

The wound healing of all the animals were observed with healing intensity, liquid scintillation counter, AgNORs staining, VG staining and transmission electron microscopy.

利用家兔自体穿透性角膜移植模型，采用测量伤口愈合强度、液闪计数、AgNORs染色、VG染色和电镜等方法，观察家兔PKP术后伤口愈合情况。

Assays of AKT and MPF activities AKT or MPF kinase activity was measured by histone H2B kinase or histone H1 kinase assay.The frozen eggs were treated with the same method as we previously reported.The radioactivity on the filter paper was counted with a BECKMAN scintillation counter.

免疫荧光分析的结果显示，结合Ser473位磷酸化AKT的绿色荧光FITC在GV期卵母细胞中均匀分布在胞浆中，而在S期的受精卵中绿色荧光分布于细胞膜，AKT的膜定位表明在S期的受精卵中它可能处于活化状态。

METHODS:U937 cells were labeled with ［3H］ thymidine in the culture medium, test reagents were added into the cell suspension in 24-well plates. The counts*min-1 were counted in a liquid scintillation counter.

［3H］-TdR标记的U937细胞培养于24孔板，在高分子激肽原，激肽释放酶(kallikrein，KK)，因子Ⅻ和纤溶酶原的作用下，观察U937细胞的粘附情况。

Mutans was purified from recombinant bacteria. GtfD was incubated in buffered-KCl solution with dextran and sucrose containing sucrose-［14C-glucose ］. The bound activity of GtfD was measured with a scintillation counter. The effects of peroxidase system and its components on the activity of GtfD were examined by incubating different components separately and together with GtfD.

变链菌GtfD由重组菌提纯， GtfD与含葡聚糖和蔗糖（含C14标记葡萄糖）的氯化钾缓冲液孵育，经闪烁计数器测定GtfD活性；过氧化物酶系统及其组份对GtfD活性的影响，通过将这些组份单独或共同和GtfD孵育得以测定。

To study the effects on the body of animals after incorporation of 3H-TdR and its mechanism, the laws of distribution A retention and absorbed dose in blood , thymus, spleen, femur, heart, lung,kidney, liver, brain , spermary , small intestine and muscle were detected by liquid scintillation counter after 3H-TdR was injected into the tail vein of mouse; the process of dynamic incorporation of in the lymphocytic cell nucleus of blood , thymus , spleen and the nucleus of femur was monitored; the absorbed dose in the cell nucleus was estimated; the influence to RNA"s synthesizing and cell"s survival was observed using the technology of CLSM; A segment of Egr-1 gene was cloned with reverse transcriptase- polymerase chained reaction, the influence to the expression of Egr-1 gene in the spleen cells was observed.
