在肿瘤的治疗研究中，化疗为不少患者解除病痛，延长生命。但与此同时，化疗药物也极大的损伤了人类造血系统，破坏了人体的正常免疫功能。各种免疫增强剂的应用，改善了患者的机体状态，但对其疗效的观察，包括对患者骨髓细胞的分析、探讨其毒性大小，大鼠做为人类的替难者，在肿瘤的研究中首当其冲。为此，我们对我所饲养的ＷＫＡ大鼠骨髓细胞进行了分析观察，为应用大鼠作实验提供依据。 In the treatment of cancer research, chemotherapy for many patients relieve pain and prolong life. But at the same time, chemotherapy drugs also greatly damage the human hematopoietic system, undermining the body’s normal immune function. The use of various immunostimulants improves the patient’s body condition, but observations of its efficacy, including the analysis of patient bone marrow cells, the extent of their toxicity, and the use of rats as human challengers, Bear the brunt. To this end, we analyzed the myeloid cells of WKA rats that were raised in our country and provided the basis for the experiments in rats.
