To own assessment of the removal balance within the rats, radioactivity is actually calculated when you look at the urine, feces, cage washings (aqueous and you can organic), and carcasses. Dried stools homogenates, cage debris, and carcass aliquots were combusted within the outdoors having fun with an excellent Packard Try Oxidizer. The carbon-14 combusted circumstances was indeed immersed from inside the Carbo-SorbR and you can mixed with PermafluorR Age+ h2o scintillant ahead of LSC. Radioactivity is actually measured of the LSC using Tri-Carbs 2300 (Packard, Dreieich) drinking water scintillation surfaces towards capability to calculate satisfy-remedied disintegrations each and every minute.
Into the pets, the complete radioactivity articles from plasma and each pee and you may stools pool is actually mentioned by the LSC using Tri-Carbs 2100 (PerkinElmer, Rodgau). Next info are supplied throughout the Extra Analysis.
For logical samples, analysis from complete radioactivity entirely bloodstream, plasma, urine, stools, and you can ended heavens (and quick counts from inside the urine and stools) is did having fun with LSC; good Packard Tri-Carbs 3100 TR liquids scintillation analyzer (Downers Grove, IL) was applied.
