Red Blood Cell Labelling by Intravenous Injection Of ^99mTC-PAEP^[*]

Summary

In vivo red blood cell (RBC) labelling after the intravenous administration of PAEP (N-phosphorylaminoethyl-phosphate) and the subsequent injection of sodium pertechnetate 24 hrs later was studied. The results in rats were found to be similar to those obtained after i.v. administration of ^99mTc-PYP, a radiopharmaceutical routinely used for in vivo RBC labelling.

Zusammenfassung

Die In-vivo-Markierung roter Blutkörperchen wurde nach intravenöser Verabreichung von PAEP (N-Phosphorylamino-aethylphosphat) und einer nachfolgenden Injektion von Natriumpertechnetat 24 Std. später untersucht. Die Ergebnisse bei Ratten waren ähnlich jenen nach i.v. Verabreichung von ^99mTc-PYP, eines Radiopharmakons, das routinemäßig zur In-vivo-Markierung von Erythrozyten verwendet wird.
