    Notes: Summary We have carried out randomized 12-week multicentre study to compare the effects of prazosin and propranolol on blood pressure and serum lipids in 70 patients with essential hypertension after a 4 week minimum period of treatment with thiazide diuretics. After 12 weeks treatment with prazosin (n=40, 1.5–12.0 mg per day) or propranolol (n=30, 30–120 mg per day) with diuretics there was a significant blood pressure reduction from 165.1/97.9 mmHg to 151.2/90.6 mmHg and from 167/96.5 mmHg to 153/91.9 mmHg, respectively. In the 12th week a significant decrease was noted in triglyceride and in low-density lipoprotein cholesterol (LDL + VLDL-C), but no significant effects were seen in high-density lipoprotein cholesterol (HDL-C) in patients receiving prazosin. On the other hand, a significant decrease in lecithin cholesterol acyltransferase (LCAT) was seen in patients receiving propranolol. Twenty-six of 40 patients receiving prazosin were given an additional 12 weeks of treatment. Twenty-two of 30 patients initially treated with propranolol were switched from propranolol to prazosin after 13 weeks and given prazosin up to the 24th week. At 24 weeks, the blood pressure was 149/93.0 mmHg in the prazosin group and 155/89.2 mmHg in the group which switched from propranolol to prazosin. Triglyceride remained reduced in the prazosin group at the 24th week. In the group which switched from propranolol to prazosin, triglyceride decreased significantly over the next 12 weeks.

    Centrifugal mass separation in rotating plasmas produced by a coaxial plasma gun (1989)

    Notes: Rotating Cu/Zn plasmas produced by a coaxial plasma gun have been applied to plasma centrifuge. A separation factor of up to 10 is measured over a radius of 4 cm when a current of 13 kA and an axial magnetic field of 2.5 kG are applied. Plasma parameters are: rotation frequency ω=1.1×106 rad/s, density n∼1015 cm−3, and ion temperature Ti=10 eV. The separation factor of 2 is attained even in the plasma core where the density is higher than one-half of the peak value. This is attributed to the fact that a strong centrifugal force forms a hollow density profile which gives the density peak at a radius of 2 cm.

    Notes: Summary The retrograde fluorescence tracer, True Blue (TB), was injected into the forebrain septal area of neonatal rats. After 3 to 6 days the brains of these animals were carefully removed and placed in ice-cold sterilized physiological saline containing 1% glucose. Under the surgical microscope, one or two pairs of mesencephalic tissue samples, each containing a dorsal raphe nucleus, were punched out and transplanted into the third ventricle of a 5,6-DHT-pretreated adult rat. One month after transplantation, all animals were perfused and their brains sectioned using a cryostat. The sections were examined using a fluorescence microscope, and then processed for serotonin immunohistochemistry. The grafts were found to be successfully implanted and connected with the middle portion of the third ventricle. Four types of neurons, i.e., TB-labeled, serotonin-labeled, both TB-and serotonin-labeled, and non-labeled neurons, were detected in the grafts. This double-labeling method is considered to be a useful technique in characterizing the neurons in grafts which consist of a heterogeneous cell population.

    A quenched carbonaceous composite (QCC) grain model for the interstellar 220 NM extinction hump (1986)

    Notes: Abstract The dependence of the wavelength of peak absorption of dust grains on the grain size is investigated analytically by using an oscillator model for the absorption band. The peak wavelength of a weak absorption band is much less sensitive to the grain size than that of a strong band. This is explained by the fact that the surface mode, which is excited in the strong absorption band, is not raised in the weak absorption band. A quenched carbonaceous composite (QCC) synthesized from hydrocarbon plasma is found to have a weak absorption band at 220 nm. The absorption peak wavelength of the QCC grains falls well in the range of 217±7 nm even if the grain size runs from 5 to 100 nm. This is compatible with the observed constancy of the 220 nm hump (217±5 nm). By contrast, the absorption peak of graphite grains, which have a strong band around 280 nm and have been investigated as candidates for the hump, is very sensitive to the grain size. A quite narrow range of the grain size is required to account for the observed 220 nm feature. A weak absorption model, such as the QCC grains, is suggested to be a more likely candidate for the 220 nm extinction hump than a strong absorption model, such as graphite grains.
