Evaluation of the effect of an extract of sabugueiro (Sambucus australis) on the labeling of blood constituents with technetium-99m
Sambucus australis (sabugueiro) has been used to treat inflammatory and rheumatologic disorders. Blood constituents labeled with technetium-99m (99mTc) have been used in nuclear medicine to obtain diagnostic images. The aim of this work was to evaluate the effect of a sabugueiro extract on the label...
