An autoradiographic study of cochlea and organs of guinea pigs after intraperitoneal injection of 125I-labelled bFGF.

The CPM value of organ samples in the 125I group was higher than that in other groups, and radioactive grain was observed in cochlear samples of this group. In the 125I-bFGF group, blood demonstrated the highest CPM value, while cochlea and brain demonstrated the lowest CPM value, with no radioactive grain observed in cochlear samples.
