BACKGROUND Human hair is one of the essential components that define appearance and is a useful source of samples for non-invasive biomonitoring. We describe a novel application of imaging mass spectrometry (IMS) of hair biomolecules for advanced molecular characterization and a better understanding of hair aging. As a cosmetic and biomedical application,(More)
Using portacaval anastomosis (PCA) rats as a model with or without injection of ammonium acetate, we investigated the effects of MHS-G on the abnormalities of electroencephalogram (EEG) and brain amines metabolism in comparison with those of SF-1008C, a commercial nutritional preparation for hepatic failure. MHS-G (0.68 g/kg, p.o.) clearly improved both the(More)
Chronic toxicity of lentinan was studied in male and female JCL : SD rats. Lentinan was given intravenously into tail vein. Dosage levels employed were 0 (5% mannitol), 0.01, 0.1, 1 (with or without dextran), and 10 mg/kg/day for 6 months in a volume of 1 ml/100 g body weight. After 6 months, the treatment was discontinued and a recovery study was performed(More)
Employing twenty fresh oral isolates of Streptococcus intermedius, studies were carried out to characterize serological relations among the isolates and also between the isolates and the strains of bacterial species closely related to S. intermedius. The Rantz-Randall extracts from the cells were used as antigens. The anti-rabbit serum raised against S.(More)
Subacute toxicity test of AMI-U-II was carried out using male and female JCL:SD rats. The animals were given intravenously AMI-U-II (80, 40 and 20ml/kg) or reference solution (80 and 40ml/kg) for five weeks. Tachypnea, depression of spontaneous activity, blepharoptosis and edema of face were observed in rats treated with AMI-U-II or reference solution at(More)
Male and female dogs, aged 17--21 months, were administered orall M 73101 (0, 60, 120 and 240 mg/kg/day), a new analgesic and antiinflammatory drug, for 27 weeks, and following recovery test was carried out for 5 weeks. Dead animals were not found throughout the experimental period. Body weight gain, and food and water consumption were not affected due to M(More)
