Persimmon, a deciduous tree of the family Ebenaceae, is found throughout East Asia and contains high levels of tannins. This class of natural compounds exhibit favorable toxicity profiles along with bactericidal activity without the emergence of resistant bacteria, suggesting potential medical applications. Consistent with these observations, persimmon(More)
A new and simple analytical method for glycarbylamide (GB) based on the formation of nickel chelate was developed. The proposed method is as follows: sample solution is mixed with 0.08 mmol/L nickel nitrate in 0.2 mol/L carbonate buffer (pH 9.0), and the absorbance is measured at 290 nm. Under the optimal conditions, GB could be determined in the(More)
We developed a novel highly sensitive chemiluminescence (CL) method for BH(4). The principle of the proposed method is based on active oxygen formation induced by 1-methoxy-5-methyl phenazinium methyl sulphate (1-methoxy PMS) in the presence of dissolved oxygen. Furthermore, active oxygen is determined by a CL assay involving the luminol reaction with(More)
We developed a highly sensitive chemiluminescent (CL) assay for hydrogen peroxide using 10-methyl-9-(phenoxycarbonyl) acridinium fluorosulfonate (PMAC) that produced chemiluminescence under neutral conditions and applied it to an enzyme immunoassay (EIA). One picomole of hydrogen peroxide could be detected using the optimized PMAC-CL method and 6.2 ×(More)
In an attempt to identify blood stains of human origin, DNA was extracted from human and animal dried blood stains and examined using recombinant DNA techniques. As a DNA probe, biotin-labeled or radioisotopically labeled human repetitive sequence 2.3 Kb Hind III fragment (pH 12) in pBR 322 was used. The probe clearly hybridized with human DNA, but not with(More)
