Conclusion Mitotic index and tumor size may be the valuable prognostic factors, however chemotherapy after operation can't improve the patients' survival.
结论核分裂指数和肿瘤体积是卵巢颗粒-间质细胞恶性肿瘤有价值的预后因素,而术后化疗并不改善患者的预后。
The cell mitotic index decreased when the concentration of MH increased in a certain range, however, the ratios of micronucleus and chromosome aberration could increase.
随着盐酸吗啉胍处理浓度的增加,有丝分裂指数降低,而微核率和染色体畸变率均升高;
Therefore, Mitotic index can be used as a reference for monitoring the formaldehyde content in the environment. Onions can be applied to formaldehyde pollution monitoring.
根尖有丝分裂指数可以作为监测环境中甲醛含量的参考指标,应用于甲醛污染的监测。
With different concentrations of sewage and aluminum sulfate as a mutagen, pea root tip cells in the mitotic index, micro-rate and the rate of chromosomal aberrations are determined.
以不同浓度的污水和硫酸铝作为诱变剂,测定豌豆根尖细胞的有丝分裂指数、微核率和染色体畸变率。

Mitotic Index(有丝分裂指数)是一个在病理学和肿瘤学中用于量化细胞增殖活性的重要指标。它具体指在显微镜下观察的组织样本中,处于有丝分裂(Mitosis)阶段的细胞数量占该视野内总细胞数量的百分比。
详细解释:
核心定义:
Mitotic Index (MI) = (Number of cells in mitosis / Total number of cells counted) × 100%
临床意义与应用:

Mitotic index(有丝分裂指数)是生物学和医学中用于衡量细胞分裂活跃程度的指标,具体解释如下:
定义 指在特定组织或细胞样本中,处于有丝分裂阶段(M期)的细胞占总细胞数的百分比。计算公式为: $$ text{Mitotic Index} = frac{text{分裂中细胞数}}{text{总细胞数}} times 100% $$
检测方法 通常通过显微镜观察经染色(如苏木精-伊红染色)的组织切片,人工计数分裂细胞。现代技术也可结合免疫荧光标记(如磷酸化组蛋白H3抗体)进行自动检测。
应用领域
该指标需结合其他参数(如Ki-67标记指数)综合评估细胞增殖状态,在临床病理报告中具有重要参考价值。
