RT Journal Article SR Electronic T1 Controlled trial of hydroxocobalamin and riboflavine in Nigerian ataxic neuropathy JF Journal of Neurology, Neurosurgery & Psychiatry JO J Neurol Neurosurg Psychiatry FD BMJ Publishing Group Ltd SP 663 OP 666 DO 10.1136/jnnp.33.5.663 VO 33 IS 5 A1 Osuntokun, B.

YR 1970 UL http://jnnp.bmj.com/content/33/5/663.abstract AB The results are presented of a double-blind therapeutic trial of hydroxocobalamin and riboflavine in Nigerian patients suffering from a degenerative neuropathy. Although no benefit from either vitamin was demonstrated, this may reflect the inadequacy of the dosages used. The results are discussed in relation to the hypothesis that dietary cyanide and cyanogens are responsible, at least in part, for the occurrence of this disease in a malnourished population.
