摘要 目的了解噻唑橙(TO)在红细胞保养液MAP液中的吸收光谱特性及其稳定性;了解红细胞(RBC)对TO吸附吸收、洗脱的动态过程。方法用MAP液配制120 mmol/L TO-MAP液,4℃避光保存,于配制后d 0、3、17,分别用可见紫外分光光度计进行350~600 nm扫描,观察其吸收光谱的变化;配制成TO-MAP-RBC悬液,于第0、2、4、12、24 h分别离心,取上清液测定其350~600 nm的扫描光谱;取储存2 d的TO-MAP-RBC液,离心弃上清,加生理盐水洗涤6次,每次间隔20 min,收集每次洗涤液,测定其350~600 nm扫描光谱。结果 MAP液中TO吸收主峰位于468 nm,在430 nm和520 nm有2处肩峰,储存0、7 d TO-MAP液扫描线几乎完全重叠,储存17 d扫描线略有降低;TO-MAP-RBC悬液0、2、4、12、24 h其上清液的扫描线有较大的降低;洗涤液的扫描光谱显示,第1~2次洗涤TO被洗脱的量较大,第3~6次洗涤TO被洗脱的量较小,并趋于平稳。结论 TO在MAP液中非常稳定,这为TO光化学病原体灭活提供了必要条件;TO可被红细胞吸附或吸收;TO洗脱的动力学过程提示,为降低TO对测定红细胞活性功能指标的影响,可增加洗涤次数及延长洗涤间隔。
