Table showing disturbances in T4/T3 Ratio:

Zhao W, Zhu H, Yu Z, Aoki K, Misumi J, Zhang X - "Long-term Effects of Various Iodine and Fluorine Doses on the Thyroid and Fluorosis in Mice"
Endocr Regul 32(2):63-70 (1998) Full Text

Groups:

ID = Iodine Deficient (0.0 ug/l)
IN = Iodine Normal (20.0 ug/l)
IE = Iodine Excess (2500 ug/l)

FD = Fluoride Deficient (0.0 mg/l)
FN = Fluoride Normal (0.6 mg/l)
FE = Fluoride Excess (30 mg/l)


	Thyroid Hormone Levels: T3 (after 100 days)

	ID	IN	IE
FD	0.49 +/- 0.27 ng/ml	1.02 +/-0.50 ng/ml	0.42 +/-0.23 ng/ml
FN	0.49 +/-0.25 ng/ml	0.95 +/- 0.09 ng/ml	0.48 +/- 0.24 ng/ml
FE	1.52 +/-0.33 ng/ml	0.90 +/- 0.45 ng/ml	0.47 +/- 0.24 ng/ml


	Thyroid Hormone Levels: T4 (after 100 days)

	ID	IN	IE
FD	45.2 +/- 14.39 ng/ml	68.2 +/- 12.80 ng/ml	68.2 +/- 12.80 ng/ml
FN	46.2 +/- 11.21 ng/ml	89.7 +/- 14.68 ng/ml	89.7 +/- 14.68 ng/ml
FE	116.9 +/- 15.13 ng/ml	101.6 +/- 18.36 ng/ml	98.8 +/- 8.20 ng/ml


	NOTE: After 150 days the T4 levels were half of those shown above in IN and IE, regardless of F- intake. In all ID groups T4 levels were hugely decreased (average values were 5.0 to 9.6 ng/ml)
