Whole-body autoradiography: further examples
Comparison of whole-body biodistribution
of 14C-ethanol at 15 min following i.v.
administration (sections A and B) with that
at 60 min following i.v. administration
(sections C and D).  
Preclinical contract research services
Biodistribution of 125I-labeled carbon
nanotubes at 2 h following i.v.
adminstration.   Nanotubes are mostly
concentrated in the lung, with smaller
levels also in the liver, kidney and intestine.
Biodistribution of [3H]MK-801 in a rat at 1 h
after i.v. administration of 50 microcuries of
radioactivity.  High levels of radioactivity in
the intestines are from hepatobillary
excretion of the compound.
