The effects of gallic acid (3,4,5-trihydroxybenzoic acid) and its alkyl esters on virus growth and virion infectivity were examined. All the compounds tested showed an inhibitory effect on the growth of herpes simplex virus type 1 (HSV-1) in HEp-2 or Vero cells. The antiviral activity of gallic acid alkyl esters was enhanced by increasing the number of(More)
Immune tolerance to organ transplants has been reported in laboratory animals and in humans after nonmyeloablative conditioning of the host and infusion of donor bone marrow cells. We examined the mechanisms of immune tolerance to mouse cardiac allografts in MHC-mismatched hosts that developed mixed chimerism after posttransplant conditioning with a 2-wk(More)
Our previous studies in mice showed that the nonmyeloablative conditioning regimen of fractionated irradiation of the lymphoid tissues (total lymphoid irradiation; TLI) and depletive anti-T-cell antibodies (anti-thymocyte serum) markedly increased the percentage of regulatory DX5+ and natural killer 1.1+ T cells in the mouse spleen, and prevented acute(More)
Octyl gallate inhibited the multiplication of several RNA viruses with widely different structure and replication strategies; i.e. vesicular stomatitis virus (VSV), influenza virus and poliovirus. In addition, octyl gallate showed virucidal activity against enveloped viruses at high concentrations. Characterization of the mode of action of octyl gallate(More)
To investigate whether the ocular dominance affects laterality in the activity of the primary visual cortex, we examined the relationship between the ocular dominance and latency or dipole moment measured by checkerboard-pattern and magnetoencephalography in 11 right-handed healthy male participants. Participants with left-eye dominance showed a dipole(More)
Adjuvant arthritis in Lewis rats is induced by the subcutaneous injection of Mycobacterium tuberculosis in mineral oil, and the predominant T cell immune reactivity is against the heat shock protein 65 derived peptide 176-190. We treated Lewis rats with human recombinant G-CSF followed by (i.v) administration of peptide 176-190 after induction of adjuvant(More)
Given the concerns surrounding the overuse of carbapenem antibiotics in Japan, we evaluated the impact of infectious disease consultation and a prospective carbapenem audit at a tertiary care center in Tokyo, Japan. Overall, carbapenem use was safely and effectively reduced after implementation of these interventions. The leadership of the infectious(More)
OBJECTIVE: Many studies of dementia mainly Alzheimer's disease (AD) by using MEG have been reported. Some results show there are some differences between patients and controls in MEG data. But it is still difficult to diagnose the disease in early stage using their methods because of large individual variation. We measured many patients and normal aged(More)
