in anesthetized dogs , structure activity relationships among three cardiotonic compounds were determined by comparing the cardiovascular effects of digotoxigenin ( the genin ) to digitoxigenin-galactose ( a genin-neutral sugar combination ) and to digitoxigenin-aminogalactose ( asi-222 , a genin-aminosugar combination ) using either bolus i.v . injections or constant i.v . infusions .
