Thiocyanate Concentration

A thyroid-hormonal evaluation of thirty-five women consuming commercially packed milk containing thiocyanate was carried out. The mean serum thiocyanate concentration, which was measured by the FeCl3colour test, was significantly higher (P< 0.01) than that of control subjects. Serum thyroxine (T4), triiodothyronine (T3) and thyroid-stimulating hormone (TSH) concentrations of exposed women were compared with those of thirty-five control subjects. Thiocyanate ingestion was associated with lower levels of T4(P<0.01) and higher levels of TSH (P< 0.01) compared with the control subjects. T3was found to be higher in the women consuming thiocyanate-containing milk but the difference was not significant. The serum T4level was found to be negatively correlated (r−0.359,P<0.05) while the TSH level was positively correlated (r0.354,P< 0.05) with thiocyanate concentration in the exposed group. From this study, it appears that ingestion of milk with added thiocyanate impairs thyroid function.

Growth And Reproduction

FEEDING of fresh and dried cassava (CMC 84 variety) containing 172.6 and 90.6mg FICN/Kg fresh material respectively caused a non-significant (P > 0.05) increase in daily feed intake as com­pared to a corn starch control diet. Growth rate of suckling rats was least on the fresh cassava diet and intermediate on the dried cassava diet. Post weaning feed consumption, growth rate and feed utilization were also considerably reduced by the cassava diets .The fresh cassava diet caused a significant (P < 0.01) increase in serum thiocyanate of Weaning Rats. At the end of the post-weaning growth study period, serum thiocyanate was significantly (P < 0.01) higher on both the fresh and dried cassava diets. Rhodanese activity changes did not show any consistent treatment effect.

Thiocyanate Concentration

The electroreduction of cobalt(II) in aqueous thiocyanate solutions at the dropping mercury electrode depends on the thiocyanate concentration. At [SCN-] = 0.3 mol/l the intermediate cobalt(I)-thiocyanate complex does exist electrokinetically and may be responsible for the appearance of a peaked catalytic wave. The predecessor species of this intermediate may be CoSCN+ and Co(SCN)2 in similarity to the behaviour of cobalt(II) with cyanide and azide ions.

Thiocyanate Concentration

1. The ingestion of cassava (Manihot esculenta Crantz) by rats increased the plasma thiocyanate concentration and reduced the thyroid iodine content and the plasma protein-bound iodine.2. Administration of increasing doses of thiocyanate raised the plasma thiocyanate concentration and reduced the thyroid iodine content and the plasma protein-bound iodine.3. In producing these effects, the daily ingestion of 10 g cassava root containing 1·6 mg cyanide was approximately equivalent to a daily intake of about 1–2 mg thiocyanate.4. These results suggest that the antithyroid action of cassava is the result of the production of thiocyanate by the rat from cyanide arising from the cyanogenic glucosides present in this food.

Concentrating Mechanism

The dependence of the ratio of the radioiodide concentrations in thyroid gland and serum ( T/S) on the serum iodide concentration for fixed serum thiocyanate concentrations was investigated in C3H mice. The empirical equation (See PDF for Equation) where [SCN–] and [I–] are the serum thiocyanate and iodide concentrations in mg %, fitted the data within the limits of experimental error. Interpretation of the empirical equation was based on simple adsorption and active transport models of the iodide concentrating mechanism. The inhibition by thiocyanate of the thyroidal iodide concentrating mechanism appears to be competitive.
