Results showed that cadmium can change the RBC of rats from normal disc erythrocyte into acanthocyte, stomatocyte, target and helmet cells.
结果表明:镉可使大鼠红细胞由正常的园盘状变成棘形、口形、靶形、盔形、点状等。
The result showed that the occurrence of acanthocyte in the glomerular bleeding(5.5%)was much higher than that in the nonglomerular bleeding(0.6%).
结果,棘形红细胞在肾性出血红细胞总数中所占的比率(5 .5 % )远高于非肾性出血(0 .6 % )。
Objective: To evaluate the value differentiating glomerular hematuria from non-glomerular hematuria with multiple urine acanthocyte (G_1 cell) counts.
目的:评价用多次尿棘红细胞计数鉴别肾小球性及非肾小球性血尿的应用价值。
Conclusion: G_1 cell is recognized easily, and it's more sensitive and accurate with acanthocyte counts of multiple urine than that of single urine for hematuria position diagnosis.
结论:与一次尿检比较,多次尿棘红细胞检查可提高棘红细胞的检出率,此法对肾小球性血尿定位诊断的准确性更好。
棘红细胞(Acanthocyte)是一种形态异常的红细胞,其特点是细胞表面有数量不等、分布不均、长短不一的棘状突起。这些突起通常较粗、末端膨大,且间隔不规则,与锯齿状红细胞的均匀分布、短小突起明显不同。

Acanthocyte(棘红细胞) 是一种异常的红细胞,其表面有多个不规则的刺状或棘状突起,间距不等。以下是详细解释:
定义与形态特征
Acanthocyte源自希腊语"akantha"(刺)和"kytos"(细胞),指在显微镜下呈现5-10个钝性、长短不一的棘状突起的异常红细胞。这种形态改变通常由细胞膜脂质代谢异常或结构缺陷导致。
临床意义
与其他红细胞的区别
需与棘形红细胞(echinocyte)区分,后者突起更细密且规则,多因体外环境变化(如pH异常)引起,临床意义较小。

同义词:棘细胞(较少用),英文文献中通常直接使用“acanthocyte”。
