Higher Sensitivity

Several studies have shown that unenhanced computed tomography (CT), while having a similar specificity to intravenous urography (IVU) for detecting ureterolithiasis, has a much higher sensitivity. CT is also more effective in identifying alternative pathologies and is known to be a much quicker investigation to perform. Additionally, CT can be used in patients with renal impairment and carries no risk of contrast reaction.

Reaction of (Et4N)Cl with AS2S3 and Na2S in acetonitrile at 110°C affords the polymeric thioarsenate(III) (Et4N)2As6S10 in which the cyclic [As3S6]3- and chainlike [As3S7]5- trinuclear molecular building units are linked together through common sulphur atoms into infinite double chains. In contrast, reaction of the same starting materials at higher temperatures (180°C) in water leads to formation of a markedly denser phase (Et4N)2As8S13, whose thioarsenate(III) 1∞ [As8S132-] anions exhibit a higher condensation grade. These likewise double chains are composed of cyclic [AS3S6]3- and dinuclear [As2Ss]4- units with shared ѱ-AsS3 tetrahedra corners. Analogous treatment of (Et4N)Cl with As2Se3 and Na2Se in acetonitrile (T =110°C) yields (Et4N)[SeAsSe7].

Quantitative Recovery

After the reaction of reduced BSAt with BPA at pH 10�6 and subsequent hydrolysis of the protein with 6N HCl, only 40% of the lysine present in the unmodified protein can be accounted for on chromatographic analysis of the hydrolysate; a similar loss is observed of the SAPC into which the original cystine, which has totally disappeared, is presumably initially all converted. In place of these amino acids, a "neutral" ninhydrin-positive peak is observed which accounts approximately quantitatively for the missing lysine. The reaction at pH 8� 6 with IP A leads to a quantitative recovery of SAPC with no loss of lysine. In contrast, reaction for the same times at both pH values with BEA leads to quantitative recovery of all amino acids including SAEC. Although the reaction ofIP A with thiols at pH 8�6 is very slow compared with that of other alkylating agents, the relative absence of side reactions may be compared with the state of affairs when methyl iodide is used for an equivalent period in the same relative quantities, when there is extensive alteration of lysine, histidine, methionine, and S-methylcysteine.
