Comparison of radioactive

Difficult to obtain an emulsion layer of constant and reproducible thickness making comparisons of radioactivity with different structures very tenuous [see ref. (7) for a thorough discussion of such comparisons as a function of isotope employed]... 

Cameron and Patrick (1966) generally confirmed their own autoradiography results quantitatively. At 48-hours post-dosing, data showed the same distribution of radioactivity for both perfused and unperfused tissue samples. A comparison of radioactivity concentration between blood and other tissues was not possible, since the... 

Fig. 5. Comparison of radioactive lipid in tectum following injection of 5yc of H-nievalonate into right eye in control goldfish and into goldfish whose optic nerve had been crushed 7 days prior to injection. Two groups of 3 fish each were averaged for each time point. Four groups v ere used for the l i-day point.
