    Notes: An onboard model of a TV camera to detect spectroscopically resolved images has been developed. It has been able to detect several spectral pictures at the same time by using only one camera with no restriction against spectral selection between each picture. The wavelength of each picture has been selected electronically. The number of spectroscopically resolved pictures is dependent only on the memory size of the computer. This camera is equivalent to a standard TV camera in which 117 bandpass filters are installed. The favorable characteristics of this camera are that it does not cause a time difference between each picture and is able to display the physical parameters by numerical calculations and can change the spectral range even after launch. The principal purpose of this model is to assist in investigating the dynamic structure of the aurora and the atmospheric composition of planets.

    Notes: 1. To determine whether coronary flow regulation by nitric oxide (NO) is impaired in the hypertensive heart (HTH), coronary perfusion was measured in isolated rat hearts using NO synthesis inhibitor L-NG-monomethyl arginine (L-NMMA) in Wistar-Kyoto (WKY) rat and spontaneously hypertensive rat (SHR) with and without chronic Nω-nitro-L-arginine-methylester (L-NAME) treatment. Moreover, the effect of angiotensin 11 receptor antagonist (AT1 receptor antagonist) (TCV-116) on the impaired coronary circulation in HTH was examined.2. Coronary flow (CF) was decreased in HTH accompanied with cardiac hypertrophy. The decreased response of CF to L-NMMA infusion was diminished in HTH. It is suggested that NO production was reduced in coronary vasculature in HTH.3. In chronic L-NAME treated SHR, blood pressure and cardiac hypertrophy were accelerated. Although coronary flow resistance (CFR) was increased, the increased response of CFR to L-NMMA infusion was not altered.4. The AT1 antagonist improved total minimal coronary flow resistance (MCFR) restoring CFR response in SHR, although it did not recover CFR response in chronic L-NAME treated SHR.5. Taken together the findings suggest that NO production was exhausted in the coronary artery even in the developing stage of hypertension and this exhaustion could contribute to the impairment of coronary circulation of HTH.

    FUNCTIONAL ALTERATION OF THE GABAB RECEPTOR IN THE BRAIN OF SPONTANEOUSLY HYPERTENSIVE RATS (1995)

    Notes: 1. We studied the ontogenetic development of GABAB receptors and their coupling to cyclic AMP formation in spontaneously hypertensive (SHR) and normotensive Wistar-Kyoto (WKY) rat brains. GABAB receptor binding to various brain regions was compared in age-matched SHR and WKY rats.2. The specific [3H]-GABA binding to the posterior hypothalamus (PH) was significantly lower in not only 4 week old (normotensive) but also 11 week old (hypertensive) SHR, when compared with age-matched WKY.3. Moreover, GABAB receptor agonists (baclofen and DN-2327)-induced suppression of adenylate cyclase activity also showed a decrease in 4 week old and 11 week old SHR PH.4. We concluded that the number and the functional responsiveness of GABAB receptors in rat brains decrease in SHR, preceding blood pressure elevation. The activity of GABABergic mechanisms may be different in the brains of SHR and WKY rats.

    ROLE OF BAROREFLEX AND CENTRAL α2-ADRENERGIC RECEPTOR SYSTEMS IN THE DIURNAL VARIATION OF BLOOD PRESSURE AND HEART RATE IN NORMOTENSIVE AND HYPERTENSIVE RATS (1995)

    Notes: 1. To elucidate whether baroreflex could contribute to manifest the diurnal blood pressure variations (DBPV) in normotension and hypertension, DBPV were recorded continuously via a femoral artery in awake normotensive (NT) rats and spontaneously hypertensive rats (SHR) with and without sinoaortic denervation (SAD). To determine the role of central cuzadrenergic receptor system in DBPV in hypertension, guanabentz (0.5–1.0 μg/kg per min) was infused in SHR.2. There were no differences in mean arterial pressure (MAP) variability (SD) of MAP of 24 h (MAP—SD/MAP) and SD of 24 h heart rate (HR—SD/HR) between SHR and NT. SAD did not elevate MAP and HR in both SHR and NT.3. However, in SAD rats, MAP—SD/MAP was significantly greater than those in sham-operated rats in both SHR and NT, while MAP—SD/MAP and HR—SD/HR did not show any difference between the two groups even after SAD. On the other hand, SAD did not augment HR—SD/HR in either strain.4. During guanabentz infusion, MAP was significantly lowered in sham-operated and SAD–-SHR. Moreover, MAP –-SD/MAP was significantly reduced in sham-operated, but it was not in SAD–-SHR.5. These findings suggest that baroreflex could suppress tonically the diurnal change of blood pressure in NT and SHR. The regulation of diurnal blood pressure by baroreflex via a central a-adrenergic receptor system may be altered in SHR.

    Electron beam emission from the EXOS-B (JIKIKEN) satellite as a powerful diagnostic tool in the magnetosphere (1984)

    Notes: Abstract In an electron beam emission experiment on board the EXOS-B (JIKIKEN) satellite (200 V, 1 mA-maximum), several types of waves are strongly excited by the beam such as plasma frequency, upper hybrid frequency, electron cyclotron frequency, their harmonics and nonlinear coupling of these waves. Measurements of these waves give information on local plasma density and magnetic field strength and it is revealed that the electron beam emission from the spacecraft is a powerful diagnostic tool in the magnetosphere. A long term observation in this electron beam experiment has provided us with the average plasma density profile in the magnetosphere. It is also useful for the detection of the plasmapause. Plasma density measurements down to the order of 10 cm−3 are possible. The instrument itself is very simple and compact, so that it will be a powerful plasma diagnostic tool in future magnetospheric and planetary explorations.

    Notes: Abstract Xanthogranulomatous cholecystitis (XGC) is a rare type of inflammatory disease of the gallbladder; this entity has also been termed fibroxanthogranulomatous inflammation, and ceroid or ceroid-like histiocytic granuloma of the gallbladder. Clinically, XGC sometimes is confused with a malignant neoplasm. Recently, we encountered a patient with XGC and Mirizzi syndrome, which was difficult to differentiate from gallbladder cancer accompanied by obstructive jaundice. It is important to realize that, pathologically, XGC is a benign disease, but that, in some cases, patients manifest an unusual clinical course.

    NMR and NQR studies in high-T c oxides: YBa2Cu3O y (6.0≤y≤6.91) (1989)

    Notes: Abstract The NQR and NMR techniques have been utilized to characterize the local oxygen coordination of inequivalent Cu sites and the electronic properties in both the normal and superconducting states of YBa2Cu3Oy (6.0〈-y≤6.91). The distinct NQR lines associated with the different oxygen-coordinated Cu sites, hence the locally differentiated charged states, have been observed. The degree of charge differentiation at the Cu(2) plane sites was found to be increased with decreasingy from 6.91, which might be related with the decrease ofT c. An anomalous temperature dependence of Cu nuclear spin-lattice relaxation timeT 1 has been observed for both the Cu(1) chain and Cu(2) plane sites fory=6.91 and it is discussed in connection with antiferromagnetic spin fluctuations in the normal state.
