    Notes: Abstract Effects of YM-14673 (Nα-[{(S)-4-oxo-2-azetidinyl}-carbonyl]-l-histidyl-l-prolinamide dihydrate), a new TRH derivative, on reserpine-induced behavioural and electroencephalographic changes were observed in comparison with those of TRH. YM-14673 antagonized reserpine-induced hypothermia and decrease in convulsion threshold in mice. The number of PGO waves recorded from the lateral geniculate body was decreased by administration of YM-14673 in reserpinized cats. The anti-reserpine activity of intravenous YM-14673 was about 8–20 times more potent than that of TRH. In inhibiting reserpine-induced hypothermia, the oral ED2°C relative to IV ED2°C as an indirect indication of absorption rate of the drugs was 15 for both YM-14673 and TRH. These results suggest that YM-14673 possesses more potent facilitatory effects on the central monoamine systems than TRH.

    Notes: Summary Seven monoclonal antibodies with neutralizing activity to equine herpesvirus-1 were produced. These recognized either an 81kD or an 88kD viral glycoprotein. Some of the antibodies were shown to protect hamsters in a passive immunization experiment.

    Notes: Abstract Stannite and sphalerite coexisting with iron sulfides (pyrite and/or pyrrhotite) from Japanese ore deposits associated with tin mineralization were analyzed. Based on the iron and zinc partitioning between stannite and sphalerite, the formation temperature and sulfur fugacity for this mineral assemblage were estimated. A good correlation between stannite-sphalerite temperatures and filling temperatures of fluid inclusions and sulfur isotope temperatures was obtained. This good correlation suggests that the stannite-sphalerite pair is a useful indicator of temperature and sulfur fugacity. It is deduced that the formation temperatures are not different for skarn-type, polymetallic vein-type and Sn-W vein-type deposits, whereas the sulfur fugacities are different; sulfur fugacities increase from the skarn-type through the Sn-W vein-type to the polymetallic vein-type deposits.

    Notes: Abstract The chemical composition of native gold and electrum from auriferous vein and gold-silver vein deposits in Japan has been analyzed and summarized. The Ag/Au ratios of native gold and electrum from these two types of deposits are distinct, i.e., 10–20 Ag at % (auriferous vein) and 30–70 Ag at % (gold-silver vein). Thermochemical calculations suggest that the Ag/Au ratio of native gold and electrum should decrease with increasing chloride concentration and temperature. This is consistent with analytical results of native gold and electrum and fluid inclusion studies. Based on the Ag content of native gold and electrum, the Fe content of sphalerite, and the estimated temperatures, it is deduced that the sulfur activity for auriferous vein-type systems was lower than that of gold-silver vein-type systems.

    Notes: Abstract Mercury contents in head hair of 58 dentists employed at the NUSD hospital and 50 dentists employed at the private hospitals or clinics were determined using neutron activation analysis. The arithmetic means were 5.8 ppm and 5.2 ppm, and geometric means were 5.4 ppm and 4.8 ppm, respectively. They were much lower than the values reported in the past year, and agreed well with those of normal Japanese men of the same age. Therefore, it was concluded that the mercury pollution in the working environment of dentists might be practically non-existent in Japan today.
