The HDL-cholesterol (HDL-Ch) concentration of 153 cerebrocascular patients within 1 year from onset and 257 controls were determined in the supernatant of serum in heparin-Ca++ precipitation method. In some patients, serum HDL-phospholipid (HDL-PL) concentrations were also determined. Liver function tests (GOT, GPT, TTT, ZST) were normal in all of these subjects, and control subjects had no adnormalities in physical findings, blood pressure, ECG, urinalysis etc.The average values in male and female controls were 65±20.9mg/dl and 65±22.3mg/dl, respectively. The value of female subjects over 55 years of age was lower than those of age-matched male and female under 54. There was no significant change by age in values of male control. In male patients with cerebral infarction, average HDL-Ch value was 55±18.6mg/dl and it was significantly lower than the control value. The value of female patients was 62±15.0mg/dl. In female, there was no significant difference between patients and control. Among the patients with cerebral infarction, the cases with angiographically demonstrated obstruction of internal carotid or middle cerebral arteries showed lower value as compared to those without such findings. In male and female patients with cerebral hemorrhage, average HDL-Ch concentrations were 55±13.3mg/dl and 60±16.8mg/dl respectively. Again only the value of male patients was significantly lower than that of control.Considering the importance of balance between atherogenic and anti-atherogenic properties of cholesterol in various lipoprotein fractions, HDL-cholesterol/total cholesterol (HDL-Ch/TC) ratio was calculated in each subjects. The average values of this ratio in healthy men and women were 0.37±0.13 and 0.37±0.14, respectively. The value of male patients with cerebral infarction was 0.30±0.10, it was significantly lower than the control value. The values of female patients with cerebral infarction, male and female patients with cerebral hemorrhage were 0.33±0.09, 0.35±0.10 and 0.35±0.11, respectively. These values exhibited no significant difference when compared with each controls. From these results, it was recognized that at a given concentration of serum total cholesterol, male patients with cerebral infarction had relatively less cholesterol in their HDL fraction as compared to healthy subjects.Serum HDL-PL concentrations in male patients either with cerebral infarction or cerebral hemorrhage, were significantly lower than the control value. The difference between female patients and control was insignificant.These results may suggest the importance of HDL-Ch for the development of cerebral atherosclerosis and subsequent cerebral infarction at least in man.

The effects of environment temperature on initiation and multiplication of transverse crack in cross-ply carbon fiber reinforced thermoplastic (CFRTP) laminates have been investigated. Static tensile tests for the cross-ply laminates and the 90° unidirectional laminates were carried out at room temperature, 93 °C and 130 °C, respectively. The transverse cracks were observed by soft X-ray photography. The tensile strength and the failure strain in the cross-ply laminates and the 90° unidirectional laminates at high temperature decreased compared to the values at room temperature. It was also found that the behavior of initiation and multiplication of the transverse cracks in the cross-ply laminates was changed due to the environment temperature. The experimental results under different temperature were analyzed by Weibull distribution on the basis of probabilistic model. Next, the energy release rate was calculated due to formation of a new micro crack based on the Weibull distribution. The predicted transverse crack density by Weibull distribution was compared with the experiment result and the reasonability of using Weibull distribution to CFRTP cross-ply laminates under high temperature was verified. It was found that the critical energy release rate of CFRTP laminates has decreased at high temperature and the experimental results showed that the matrix strength was decreased at high temperature. Also, the fiber-matrix interfacial fracture on the fracture surface of the 90° unidirectional laminates was observed in some areas at high temperature whereas the matrix fracture was observed at room temperature. Therefore, it was suggested that the interface strength between polymer and fiber was decreased at high temperature.

寛文3年(1663)本屋太兵衛版。唐の玄宗皇帝が楊貴妃を溺愛して治世が乱れ、忠臣の将軍司馬頓は都を離れ、隙に乗じた安禄山の反乱で楊貴妃は殺され、玄宗も都を落ちる。玄宗は方士に楊貴妃の魂魄を尋ねさせ、方士は蓬莱山(日本の熱田)で熱田大明神である楊貴妃に会い簪を持ち帰る。将軍司馬頓は白楽天の智恵を借りながら安禄山を討ち、玄宗を帰洛させる。本書は6段の構成と段初の「さる間」の語などに浄瑠璃の痕跡を残すが、書物の版式は通常の浄瑠璃本とは異なり、書型、挿絵、本文の字様など、通常の仮名草子の形態を持っている。屋代弘賢(1758−1841)の「不忍文庫」、徳島藩の「阿波国文庫」の印記がある。(岡雅彦)

ナメクジ類が硫酸銅を忌避するといわれていたが濃度などについて研究は行われていなかった. われわれはチャコウラナメクジが銅板及び硫酸銅を用い忌避効果をたしかめ, 銅板では巾20mm以上, 硫酸銅では10mM以上を必要とすることを明らかにした.

Gas hydrate, an ice-like solid compound composed of methane and water molecules, was “re-discovered” from ocean sediments in the mid-20th century, while it had been known as a chemical material to chemists and chemical engineers even in the early 19th century. Since the re-discovery of natural gas hydrate it has been attracting growing interest among geoscientists from the viewpoint of potential natural gas resources, possible impact on global environmental changes, and trigger of geo-hazards such as landslides and coastal erosion. The development of gas hydrate science has been marked by a rapid increase of studies in publications from 1991 to 1999, reflecting ODP expeditions to the mid-America Trench and Blake Ridge, where deep corings recovered solid gas hydrate samples. The number of papers in international journals has increased to 500 to 600 annually in the last few years. Recent development of marine geology and geophysics, in particular of the Ocean Drilling Program (ODP), has dramatically increased our knowledge of gas hydrate and related phenomena. Bottom simulating reflector (BSR) on seismic profiles corresponds to the base of the gas hydrate zone in sediments, and is considered to be a useful tool to identify the distribution of marine gas hydrates. The base of gas hydrate stability (BGHS) is determined from P-T conditions of sediments and water depth, and BSR is expected to occur at the depth of BGHS. However, BSR is not always consistent with BGHS; and, in some cases, even two BSRs are identified at around the depth of BGHS. These observations seem to imply that marine gas hydrate is not necessarily stable at the present position but represents ephemeral and transient conditions.  Integrated research activities of scientific projects and industry exploration efforts have identified two types of gas hydrate in marine sediments. These are deep-seated, stratigraphic-type deposits and shallow/structural accumulation. Japan's long-term exploration project led by Ministry of Economy, Trade and Industry (METI) has been targeting the stratigraphic type in the Nankai Trough, where 40 tcf of methane has been estimated to occur as concentrated gas hydrate deposits. Shallow accumulations are usually associated with gas chimney structures, and are common throughout the marginal seas of the western Pacific. Massive accumulation of the shallow type seems to be promising for gas production from gas hydrate as well.  Sudden and major changes to the earth's environment and mass extinctions are characterized by sharp negative excursions of carbon isotopic composition. Massive dissociation of C-13 depleted gas hydrate with δ13C of -40 to -100‰, is believed to have caused such global changes. The Paleocene-Eocene boundary event (PETM event) is the best-explained case of gas hydrate-induced biotic overturn. However, serious problems have recently emerged from considerations of thermal propagation through sediments. A sudden increase of methane concentration at the Last Glacial Maximum has also been considered to result from gas hydrate dissociation, but the response of gas hydrate was not so simple during the Quaternary, when low sea level during glacial periods possibly de-stabilized subsurface gas hydrate, unlike the PETM of ice-free ocean.
