Derivative spectrophotometry in the determination of metal ions with 4-(pyridyl-2-azo)resorcinol (PAR).

Derivative spectrophotometry has been applied for the elimination of the mutual spectral interferences and the analysis of binary, ternary and quaternary mixtures of complexes of microgram amounts of divalent ions of cobalt, copper, lead, manganese, nickel, zinc and iron with 4-(pyridyl-2-azo)resorcinol (PAR) in the range of 0.05-1 microg/ml (0.2-4 microg/ml for lead). The first derivative spectra can be used for the determination of both components in the majority of binary mixtures except of Cu(II) and Co(II) and systems containing Fe(II). The second and the third derivative spectra allow to determine one constituent in some ternary and quaternary mixtures.

Infective endocarditis due to the CDC group M6 bacillus.

Although staphylococcal endocarditis has occasionally been associated with a TTP-like syndrome, a similar syndrome has not been reported with endocarditis due to aerobic gram-negative rods. We report a case of subacute bacterial endocarditis with a thrombocytopenic syndrome that at first resembled TTP which was due to an unusual gram-negative rod. This case emphasizes the need for repeated examination of the bacteremic patient to detect the changing murmurs of endocarditis.
