Twenty Chemical Element Contents in Normal and Cancerous Thyroid

“…Values obtained for Br, Ca, Cl, Cr, Cu, Fe, Hg, I, K, Mg, Mn, Na, Rb, Sb, Sc, Se, and Zn contents in the normal human thyroid (Table 4) agree well with median of mean values reported by other researches [41][42][43][44][45][46][47][48][49][50][51][52][53][54][55]. The obtained means for Ag and Co were almost one order of magnitude lower whereas mean for Sr was almost one order of magnitude higher median of previously reported means but inside the range of means (Table 3).…”

Levels of chemical element contents in thyroid as potential biomarkers for cancer diagnosis (a preliminary study)

“…Thus, if we accept the chemical element contents in thyroid glands in the control group as a norm, we have to conclude that with a malignant transformation the levels of Al, B, Br, Ca, Cl, Cu, K, Mg, Mn, Na, P, and S in thyroid tissue significantly increased whereas the levels of I drastically decreased. 120.33 (-) [45] 420 (25) [46] 10.5 ± 13.4 B 0.151 (2) 0.084 (3) [47] 0.46 (3) [47] 0.476 ± 0.434 Ba 0.67 70.0084 (83) [48] ≤ 5.0 (16) [49] 1.12 ± 1.15 Br 18.1 (11) 5.12 (44) [50] 284 ± 44 (14) [51] 16.3 ± 11.6 Ca 1600 (17) 840 ± 240 (10) [52] 3800 ± 320 (29) [52] 1663 ± 999 Cl 6800 (5) 804 ± 80 (4) [53] 8000 (-) [54] 3400 ± 1452 Cu 6.1 (57) 1.42 (120) [55] 220 ± 22 (10) [53] 3.93 ± 1.43 Fe 252 (21) 56 (120) [55] 2444 ± 700 (14) [51] 223 ± 95 I 1888 (95) 159 ± 8 (23) [56] 5772 ± 2708 (50) [57] 1841 ± 1027 K 4400 (17) 46.4 ± 4.8 (4) [53] 6090 (17) [49] 6418 ± 2625 Li 6.3 (2) 0.092 (-) [58] 12.6 (180) [59] 0.0208 ± 0.0154 Mg 390 (16) 3.5 (-) [45] 840 ± 400 (14) [60] 296 ± 134 Mn 1.82 (36) 0.44 ± 11 (12) [61] 69.2 ± 7.2 (4) [53] 1.28 ± 0.56 Na 8000 (9) 438 (-) [62] 10000 ± 5000 (11) [60] 6928 ± 1730 P 3200 (10) 16 (7) [63] 7520 (60) [50] 4290 ± 1578 S 11000 (3) 4000 (-) [54] 11800 (44) [50] 8259 ± 2002 Si 16.0 (3) 0.97 (-) [45] 143 ± 6 (40)…”

The Hypothalamic-Pituitary-Thyroid Axis in Infants and Children: Protection from Radioiodines

“…For euthyroid adults the thyroidal iodide stores (organified iodide) are estimated to be between 10 and 20 mg [25]. In Venezuelan population, Zabala et al reported a median of 15 mg of thyroidal iodide content for adults, with a range of 4 to 37 mg of thyroidal iodide (Table 3) [20]. Fisher and Oddie reported a mean value of 15 mg iodide in thyroids of 8 young adults from the United States with a range of 9.0 to 23.6 [22].…”
