I . In the aetiopathogenesis, in Nigerians, of a degenerative neuropathy known as tropical ataxic neuropathy, chronic cyanide intoxication is believed to be the most important factor. The source of the cyanide is cassava (Manihot) and in Nigerian patients, plasma concentration of thiocyanate, a major detoxication product of cyanide, is high. 2. Since there is considerable doubt as to whether cy...

A flow-through spectrophotometric bulk optode for the flow-injection determination of thiocyanate is described. As active constituents, the optode incorporates the lipophilized pH indicator 5-octadecanoyloxy-2-(4-nitrophenylazo)phenol and methyltridodecyl ammonium chloride, dissolved in a plasticized poly(vinyl)chloride membrane entrapped in a cellulose support. The optode is applied, in conjun...

A new series of bimetallic complexes Co(II), Cd(II) and Hg(II) with Schiff base ligand (N,N',-Bis(Benzylidene)-1,3-Phenylenediamine, {BENDAMB (1,3)} have been synthesized characterized by elemental analysis, molar conductance, magnetic moment measurements, IR, Electronic 1H NMR spectral studies. The softness parameter TEn also calculated to derive the binding side thiocyanate ligand. data shows...

The Colorado River is contaminated with low levels of perchlorate. Perchlorate has the potential to disrupt thyroid function by inhibiting the uptake of iodide. Brassica are rich sources of thiocyanate and nitrate, also inhibitors of iodide uptake. This study was conducted to estimate potential human exposure to perchlorate, thiocyanate, and nitrate from Brassica sp. irrigated with Colorado Riv...

Previous studies (Jakobi, Jakobi, and Cavalcanti, 1961) have suggested that the concentration of thiocyanate in the saliva of patients suffering from oesophageal or gastric cancer is unusually low compared with that in normal subjects or patients with peptic ulcer. If this were confirmed the measurement of salivary thiocyanates might provide a screening test for gastric cancer. Salivary thiocya...

removal of thiosulfate (s2o32-, 200 mg/l) from simulated wastewater samples was investigated under varying co-pollutants and ph conditions employing the titanium dioxide (tio2) mediated photocatalysis. for thiosulfate only studies higher substrate removal was noted at lower ph with a specific trend of ph 4 > ph 7 > ph 10. furthermore, near complete thiosulfate removal was also achieved at ph 4....

Carboxyhaemoglobin and plasma thiocyanate concentrations were found to be significantly correlated with self-reported daily cigarette consumption in 360 smokers (r = 0.416 and 0.412 respectively; p less than 0.001). The extent to which inhalation patterns affected the intake of cigarette smoke constituents was determined from the partial correlation between carboxyhaemoglobin and plasma thiocya...
