我们应用高强度聚焦超声 (ＨＩＦＵ )治疗Ｗ 2 5 6肝癌荷鼠 ,并通过四唑蓝(ＭＴＴ)比色法观察荷癌鼠外周血淋巴细胞杀癌细胞活性的变化 ,旨在通过淋巴细胞功能的变化反映高强度聚焦超声对荷癌鼠免疫的影响 ,为其临床应用提供依据。现将结果报道如下。一、材料和方法1.模型的制?
We used high-intensity focused ultrasound (HIFU) to treat W 256 hepatocarcinoma mice and observe the change of tumor cell activity in peripheral blood lymphocytes of cancer-bearing mice by tetrazolium blue (MTT) colorimetry to aim at lymphocyte function. The changes reflect the impact of high-intensity focused ultrasound on cancer-bearing mice and provide a basis for their clinical application. The results are reported below. First, materials and methods 1. The model of the system?
