Biodistibution of 2,6 diisopropyliminodiacetic acid 99mTc (Disida-99mTc) in normal rats and with experimental hepatic lesion

Description

The biodistribution and elimination of 99mTc-DISIDA were examined by performing scintigrams on rats at different times. Normal animals (rats) and those with experimental hepatobiliary alterations were used. Results showed a delayed clearance of 99mTc-DISIDA into the small intestine of the experimental animals. The elimination of the labelled compound by the kidney was 14% dose/g 120 minutes after the injection of which 70% was found in its original form. The data indicate that in spite the compound is intact in bile it undergoes a degradative process, not yet known. (author)

Abstract (Portuguese)

A biodistribuicao e eliminacao do DISIDA- 99mTc foram estudadas em ratos por meio de cintilografia linear em diversos tempos da sua evolucao metabolica. Os animais utilizados na deteccao deste radiofarmaco foram ratos normais e com alteracao hepatica experimental. Verificou-se uma demora na passagem do DISIDA- 99mTc do figado ao intestino delgado nos ratos pre-tratados em relacao aos ratos normais. Seguindo-se a via metabolica hepato-biliar da substancia marcada, notou-se que embora esteja praticamente intacta atraves da bile, ela sofre um processo de degradacao ainda desconhecido, sendo eliminada via renal com 70% da sua integride 120 minutos apos a administracao da dose tracadora.
