Similar concentrations of thyroidal iodothyronines and T3/T4 ratio in normal thyroids from two Yugoslav districts with different iodine intake.
In spite of different daily iodine intake in two yugoslav districts (littoral-Split 297 +/- 76 (Mean +/- SD) and continental-Zagreb 111 +/- 36 micrograms/g creatinine, p less than 0.001), thyroidal iodothyronine concentrations and T4/T3 ratio in normal post mortem thyroids were comparable. T4 was 260.0 +/- 42.6 micrograms/g w.w. (Mean +/- SE) in Split group vrs. 279.9 +/- 59.4 in Zagreb. T3 was 12.8-2.0 vrs. 12.8 +/- 2.2 and T4/T3 ratio 21.6 +/- 1.9 vrs. 21.1 +/- 2.9 in Split and Zagreb, respectively. It has been concluded that relatively small difference in iodine intake has no effect on thyroidal concentrations of iodothyronines and T4/T3 ratio.
