    Notes: Escherichia coli in phosphate-buffered saline irradiated with far-infrared (FIR) energy was injured and killed even under the condition where the bulk temperature of the suspension was maintained below the lethal temperature. Using four kinds of antibiotics (penicillin G, chloramphenicol, nalidixic acid and rifampicin), we investigated the FIR irradiation-induced damage to E. coli on the basis of the sensitivity changes to the antibiotics. FIR irradiation increased the organism’s sensitivity to rifampicin both below and above the lethal temperature. The increase in sensitivity to chloramphenicol was observed only when FIR irradiation occurred above the lethal temperature. These results suggest that the mechanism of FIR irradiation-induced death in E. coli differs according to whether the radiation exposure occurs above or below the lethal temperature.

    Notes: Abstract Antineutrophil cytoplasmic antibodies (ANCA) have been reported to be associated with systemic vasculitis. However, the roles of ANCA subtypes in patients with IgA nephropathy remain to be fully investigated. We describe three Japanese patients with IgA nephropathy complicated by ANCA-associated vasculitis. Two patients with IgG class ANCA developed rapidly progressive renal failure and demonstrated mesangial proliferation with extensive extracapillary proliferation and segmental glomerular necrosis. One patient with IgM class ANCA showed severe extrarenal symptoms, such as lung fibrosis and neuritis, in addition to glomerular crescent formation. All three patients received immunosuppressive therapies, including corticosteroids and cyclophosphamide. The two patients who received these treatments early showed improvement in urinary protein excretion and renal function, in accordance with a decrease in the serum titer of ANCA. However, one patient in whom serum creatinine was already elevated showed a poor response to the treatment. These results suggest that ANCA subtypes may participate in the pathogenesis of crescent formation in patients with IgA nephropathy, and that early treatment with a combination of methylprednisolone pulse therapy, oral prednisolone, and cyclophosphamide pulse therapy may be beneficial in these patients.

    Notes: Abstract Amelogenins were extracted from the thin outer layer of porcine secretory enamel and purified by gel filtration and reverse-phase HPLC. The results of amino acid sequencing of the purified porcine amelogenins indicated the presence of at least four prototype amelogenins translated from alternatively spliced transcripts. The results of mass spectroscopy of the CNBr-cleaved peptides derived from the 25kDa amelogenin indicated that porcine 25kDa amelogenin is neither phosphorylated nor glycosylated.
