UNLABELLED Volatile anesthetics may be used to treat status epilepticus when conventional drugs are ineffective. We studied 30 cats to compare the inhibitory effects of sevoflurane, isoflurane, and halothane on penicillin-induced status epilepticus. Anesthesia was induced and maintained with one of the three volatile anesthetics in oxygen. Penicillin G was(More)
UNLABELLED Large concentrations of sevoflurane and isoflurane, but not halothane, induce spikes in the electroencephalogram. To elucidate whether these proconvulsant effects affect lidocaine-induced seizures, we compared the effects of sevoflurane, isoflurane, and halothane in cats. Fifty animals were allocated to 1 of 10 groups: 70% nitrous oxide (N2O),(More)
A 52-year-old Japanese woman presented with optical symptoms, including left-sided myodesopsia, blurred vision, narrowed visual field, and diminished visual acuity. Ocular evaluation revealed a metastatic tumor in the choroid. Further examinations identified pulmonary adenocarcinoma as the primary tumor. Because an epidermal growth factor receptor gene(More)

We compare the recent COSY data on the total pp→pΛK + and pp→pΣ 0 K + cross sections with the predictions from two boson exchange models that either are based solely on π and K exchange or include π, η and ρ exchange as well as the virtual excitation of intermediate baryon resonances. Both models are found to reproduce the data after the inclusion of final(More)
A 19-year-old female was admitted to our hospital because of a sudden onset fever and cough, and she was diagnosed to have acute eosinophilic pneumonia (AEP). The cause was thought to be cigarette smoking, because she had started smoking just before the development of AEP and her condition improved after cigarette smoking cessation, without corticosteroid(More)
Human neutrophil elastase (HNE) exists in high concentrations in airway secretions and produces mucus hypersecretion in patients with chronic obstructive pulmonary disease (COPD). L-carbocisteine improves the quality of life and reduces exacerbation in COPD patients. However the precise mechanism is uncertain. We examined the effects of L-carbocisteine on(More)
It has been recently conjectured by Selem and Wilczek [1] the existence of a ss − [¯ u ¯ d] meson due to strong correlations between the two light antiquarks. We make a detailed study of this system within a dynamical quark model which has proven to be successful in reproducing the most important features of low-energy hadron phenomenology. Our results,(More)
We study both the spin-average and spin-dependent structure functions of the lithium isotopes, 6−11 Li, which could be measured at RIKEN and other nuclear facilities in the future. It is found that the light-cone momentum distribution of the valence neutron in the halo of 11 Li is very sharp and symmetric around y = 1, because of the weak binding. This(More)
In order to guide the extrapolation of the mass of the rho meson calculated in lattice QCD with dynamical fermions, we study the contributions to its self-energy which vary most rapidly as the quark mass approaches zero; from the processes ρ → ωπ and ρ → ππ. It turns out that in analysing the most recent data from CP-PACS it is crucial to estimate the(More)
