一种新的用于血池显像的~(99m)Tc标记红细胞的药盒已在受试者中得到评价.此法用不着在标记或注射之前分离血浆和红细胞,也用不着离心和洗涤.将全血加入一个反应小瓶中,其中盛有含亚锡量50μg的枸缘酸亚锡.另外再加入次氯酸钠(1%溶液0.6ml)以阻止红细胞外的过锝酸盐过早还原.该药盒(Mp-988)已由Mallinckrodt公司制成. A new kit of 99m Tc-labeled erythrocytes for blood pool imaging has been evaluated in subjects without the need to separate plasma and red blood cells prior to labeling or injection, without centrifugation and washing The whole blood was added to a reaction vial containing stannous citrate, which had a stoichiometric amount of 50 [mu] g, and sodium hypochlorite (0.6% 1% solution) was added to prevent the premature erythrocentesate peritrochloric acid reduction. The kit (Mp-988) has been made by Mallinckrodt.
