Hydrothermal circulations supply a huge amount of chemical species into the deep sea. More than 99% of chemical species emitted from high-temperature hydrothermal fluids flow into the deep sea and construct deep-sea hydrothermal plumes. Observations of hydrothermal plumes have led studies of deep-sea hydrothermal vents, such as locating deep-sea hydrothermal vents, locating deep-sea volcanic eruptions, and calculating geochemical fluxes from sub-seafloor to deep ocean. Hydrothermal plumes affect the microbial community in deep seas by supplying many reduced chemicals, which are possible energy sources of chemolithotrophic microbes. This paper (1) reviews physical, chemical, biological studies of hydrothermal plumes and (2) discusses novel field survey technology and ecological infection of sub-seafloor to the deep-sea environment.

The present paper deals with the effects of Reserpine on 36 psychoses which were treated in our clinic since December 1954. Twenty schizophrenics, five manic depressives, two epilietics, 3 general paresises, two cerebral arterioscleroses, two feeblemindeds and two other cases were studied. 31 cases of the total cases were preveiously treated with EST or other specific treatments.0.5 mg of Reserpine were given orally for 30-50 days, or 0.5-1.0mg of Reserpine were given initially, and succeedingly the dose was increased to 3-5 mg per day and the last dose of 10-20 mg was continuously administered for 30-50 days.1) 7 out of the 20 schizophrenics (35.0%) and all of the 5 manic depressives (100%) were much or completely improved, while 4 schizophrenics were unchanged. In two of the two psychomotor epileptics, some degrees of improvement were evident, while most symptoms in the organic psychosis such as general paresis or cerebral arteriosclerosis were unchanged or poorly improved.2) Reserpine treatment was most effective on emotional disturbances such as irritability, excess or instability, and more effective on catatonic psychomotor disturbances such as negativism, mutism, excitement or stupor than on delusion or hallucination.3) The group, treated with more than 400 mg of Reserpine, was more improved than the group, treated with less than 400 mg, while better result was found in the group treated for more than 45 days than the group treated for less than 45 days.4) During the observation period of one year, 6 cases of 16 schizophrenics (37.5%), 3 cases fo 5 manic depressives (60.0%) and one of the two epileptics have recurrented or relapsed.

<p>沖縄トラフ南部、多良間島の北約60kmの海底に位置する多良間海丘で、2017年8月、調査船「よこすか」によるYK17-17研究航海において有人潜水艇「しんかい6500」の潜航調査により、300℃を超える高温の熱水噴出孔が水深1,840m付近の海底についに発見され、YZサイトと名付けられた。この海丘では2009年に実施された潜航調査により山頂付近から周囲の海水温度に比べ約20℃高い熱水の湧出が確認され、その湧水と関連すると考えられる鉄酸化物を主体とした堆積物が認められていたが(Foxサイト)、高温熱水の噴出は確認されていなかった。この海丘は南部沖縄トラフの主たるrifting zoneである八重山海底地溝のやや南に位置し、西表島北北東海底火山にあたる石垣海丘群に東側延長にあたる島弧火山列の一つと推定される。2017年の潜航調査では、両サイトから、熱水、チムニーなどの採取が行われた。本発表では得られたチムニー試料の鉱物組成や元素組成と、熱水の地球化学的特徴について報告する。</p>
