    Notes: Summary The in vivo binding of [3 H]N-methylspiperone (NMSP) and [3 H]raclopride was compared in mice treated with reserpine (5 mg/kg, 24 hr prior to the tracer injection). With both radioligands, selective accumulation of radioactivity in the striatum following intravenous injection was observed, whereas a relatively low accumulation and a rapid decline in radioactivity in the cerebellum was seen. Reserpine significantly decreased [3 H]NMSP binding in vivo, however it increased [3 H]raclopride binding. By compartment model analysis, it was found that the decrease in [3 H]NMSP binding was primarily due to the decrease in the association rate (K3) and the increase in [3 H]raclopride was due to the decrease in the dissociation rate (K4) in vivo. As both Kd and Bmax of dopamine D2 receptors have been reported to be unaltered by reserpine, these results suggested that some unknown factors except Kd and Bmax which influence on in vivo binding of receptors might be changed by reserpine. These results revealed that it is of importance to measure kinetics of ligand-receptor binding in vivo rather than static analysis. These two different types of radioligands can be combined to reveal functional roles of dopamine receptor in vivo, especially in the study of the human brain with positron emission tomography (PET).

    Notes: Abstract The capacitance and voltage characteristics of field effect transistors passivated by BaF2-B2O3-GeO2-SiO2 glasses with various water contents were investigated. As the OH absorption coefficients of the glass increased, adverse effects on the recovery of hysteresisC-V curve shifts was seen. The water content is related to the fluoride content of the BaF2−B2O3−GeO2−SiO2 glass. The viscous flow point of the glass was lowered with increasing ionic character obtained from Hannay's equation. The source-drain current and voltage (I-V) characteristics of typical enhancement and depletion mode field effect transistors passivated with these glasses were investigated.

    Notes: Abstract The capacitance and voltage (C-V) characteristics of Metal-Oxide-silicon (MOS) capacitors passivated by CaF2B2O3-GeO2-SiO2 glasses with OH− ions, water and fluoride contents were investigated. As the OH− absorption coefficients of the glass increased, adverse effects on the recovery of hysteresis C-V curve shifts was observed. The content of OH− ions is closely related to the fluoride content in the CaF2 B2O3-GeO2-SiO2 glass. The viscous-flow point of the glass was lowered with increasing degree of ionic character obtained from Hannay's equation.

    Notes: Abstract The capacitance and voltage (C-V) characteristics of metal, oxide, and semiconductors (MOS) capacitors passivated by SrF2-B2O3-GeO2-SiO2 glasses with various water and fluoride contents were investigated. As the OH− absorption coefficient of a glass increased, adverse effects on the recovery of shifts of the hysteresisC-V curve have been observed. The water content of ions is closely related to the fluoride content in the SrF2-B2O3-GeO2-SiO2 glass. The viscous-flow transition point of glass was lowered with increasing degree of ionic character obtained from Hannay's equation.

    Notes: Abstract Arterial blood ketone body ratio, reflecting hepatic mitochondrial redox state, was measured in 26 brain-dead patients who were hypotensive but hemodynamically stable. All of them had substantially normal hepatic function. In 18 of the patients, blood ketone body ratio was maintained within the normal range in spite of hypotension. This was in marked contrast to the markedly decreased blood ketone body ratio often observed in patients in shock. This phenomenon was especially conspicuous in those who had not received exogenous dopamine infusion. It is suggested that hepatic mitochondrial redox state can probably be maintained despite systemic hypotension in brain-dead patients. Dopamine administration, on the other hand, is suggested to be a contributing factor to the reduction of hepatic mitochondrial redox state in hypotensive brain-dead patients. This study may provide a guideline for effective preservation of hepatic function in the body of brain-dead patients.

    Notes: Summary We produced transgenic (Tg) mice carrying the human tyrosine hydroxylase (TH) gene. To investigate differences in the dopaminergic (DAergic) neuronal activity between the Tg and nTg mice, we examined changes in the locomotor activity induced by methamphetamine (MAP) and nicotine (NIC), which enhances DA release and induces TH enzyme activation, respectively. Surprisingly, however, the intensity of MAP (2.5 mg/kg, once a day for 14 days)-induced hyperlocomotion in the nTg mice was greater than that in the Tg mice, and, furthermore, the Tg mice were less sensitive to subacute administration of NIC (0.5 mg/kg, once a day for 14 days) than the nTg mice. These results suggest that DAergic neuronal function is suppressed in Tg mice to compensate for the overexpression of TH.
