Fig. 5. Radioactivity of iodide, thyroid hormone and thyroid hormone conjugates
fractions, shown as the percentage of the total dose remaining in the fish at
the time of sampling per gram of plasma, after Sephadex LH-20 chromatography
at 2, 24, 48 and 96 h after i.p. 125I injection in tilapia (,
N=6) and carp (
, N=6). Results are means ± s.d.
One-way ANOVA was used for statistical evaluation. Significantly different
levels of radioactivity compared with that at 2 h are indicated for tilapia
(*P<0.05, **P<0.01,
***P<0.001) and carp (+P<0.05,
++P<0.01, +++P<0.001).
