OBJECTIVE Somatosensory evoked magnetic fields (SEFs) were recorded to investigate the interaction of the somatosensory inputs using the modality of electrical finger stimulation in 6 normal subjects. METHODS Electrical stimuli were given to the index (II), middle (III) or little (V) fingers individually, and also to pairs of either the II and III(More)
1. The effect of experimental ischaemia on the response to gamma-aminobutyric acid (GABA) was assessed in acutely dissociated CA1 pyramidal neurones of rats, using the patch-clamp technique. 2. Rapid application of 3 x 10(-5) M GABA induced a bicuculline-sensitive inward Cl- current (IGABA) at a holding potential (Vh) of -44 mV. The peak amplitude of IGABA(More)
BACKGROUND An increase in the incidence of hepatocellular carcinoma (HCC) in Japan since the 1980s suggests an imminent outbreak in other countries where viral spread occurred more recently. Interferon therapy for chronic hepatitis C, in general, has been shown to prevent HCC. AIMS To determine the scale of benefit in individual patients. SUBJECTS(More)
Effects of selective Ca2+ channel blockers on GABAergic inhibitory postsynaptic currents (IPSCs) were studied in the acutely dissociated rat nucleus basalis of Meynert (nBM) neurons attached with nerve endings, namely, the "synaptic bouton" preparation, and in the thin slices of nBM, using nystatin perforated and conventional whole-cell patch recording(More)
The genetic basis of human autoimmune diseases is receiving increasing attention. Primary biliary cirrhosis (PBC) is a model autoimmune disease reflective of other organ-specific autoimmune pathology. PBC is an enigmatic autoimmune disease that predominantly affects women and leads to destruction of intrahepatic bile ducts. The serological hallmark of this(More)
It is known that aquaporin (AQP) 5 expression in the apical membrane of acinar cells in salivary glands is important for the secretion of saliva in rodents and humans. Although heat acclimation enhances saliva secretion in rodents, the molecular mechanism of how heat induces saliva secretion has not been determined. Here, we found that heat acclimation(More)
The effects of histamine on high-voltage-activated Ca2+ channels in the histaminergic neurons acutely dissociated from the rat tuberomammillary nucleus were investigated in the nystatin-perforated patch recording mode under voltage-clamp conditions. Histamine suppressed the high-voltage-activated Ca2+ channel currents in neurons which were positive for(More)
Seven patients with selective IgM deficiency (SIgMD) were studied for cell surface immunoglobulin (SmIg), T-cell subpopulations, and immunoglobulin (Ig) synthesis in vitro by peripheral blood lymphocytes (PBL). Serum IgM levels were less than 25 mg/dl, while IgA, IgG, and IgD were within normal levels. The patients had respiratory or urinary tract(More)
We investigated the effects of organic Ca2+ channel blockers, diltiazem and verapamil, on the high voltage-activated P-type Ca2+ channels in freshly isolated rat Purkinje neurons. Both diltiazem and verapamil blocked P-type Ca2+ channel current without any change in the current-voltage relation. The block was concentration-dependent. In the presence of(More)
Effects of Zn2+ and other polyvalent cations on glycine-induced currents in the freshly dissociated rat dorsal motor nucleus of the vagus neurons were investigated under voltage-clamp conditions by the use of the nystatin-perforated patch recording configuration. Glycine evoked a Cl- current in a concentration-dependent manner with a half-maximum effective(More)
