158名の肝硬変症と79名の原発性肝細胞癌患者を血清中HBs抗原の存否,日本酒1日1合以上10年間以上の飲酒歴の有無によりI群:HBsAg(+),飲酒歴(-),II群:HBsAg(+),飲酒歴(+),II群:HBsAg(-),飲酒歴(-),IV群:HBsAg(-),飲酒歴(+)の4群に分け,それら患者の診断確定時の年齢を比較した.肝硬変に関しては飲酒歴を有するII群,IV群の年齢が飲酒歴のないI群,III群に比して共に8歳若く,II群の年齢が39歳で一番若かった.又1日日本酒にして1合以上の飲酒歴のある者では飲酒量の程度は肝硬変の診断時期の年齢に影響せず,1日1合以上3合未満の飲酒でも肝硬変と診断される時期は有意に早かった.原発性肝細胞癌については,HBs抗原保有者において,1日1合以上の飲酒歴がある患者ではその原発性肝細胞癌としての診断確定時の年齢は有意に9年若かった.HBs抗原陰性の者において,1日5合以上の飲酒歴がある患者では,原発性肝細胞癌としての診断確定時の年齢は飲酒歴のない者に比して有意に9年若かった.以上の結果から,長期間にわたる飲酒は肝硬変の進展の重要な促進因子の1つとなっている可能性が考えられる.又原発性肝細胞癌の発生に関しても,長期間の飲酒が1つの促進因子となっている可能性があり,HBs抗原保有者においては軽度の飲酒(1日1合以上3合未満)もつつしむべきである.又HBs抗原陰性者においては大量の飲酒(1日5合以上)をひかえるべきである.

In view of good properties of hollow glass micro-sphere such as lightness, thermal insulating and sound arresting properties, high melting point and incombustibility and ability to increase quantity, some new composites of unparalleled characteristics are being developed by mixing them into plastics, carbon, cement, lime and its kind and metals. For instance they are now being used in diverse fields for making synthetic wood, master model, electric accessories, materials of low thermal conductivity ceramics, including aircraft materials and submarine diver-ship materials, and their demand is rapidly increasing. So, some methods to produce them have been invented already, but as the processes of them are rather complicated and the materials are expensive, the production become very expensive, too. Hereon, we authors discovered that hollow glass micro-sphere can be produced from the "Shirasu", which is acidic volcanic ejecta and one of the unutilized mineral resources distributes widely in southern Kyushu and other districts in Japan, through simple and inexpensive method. Incidentally, we will call it as "Silas Balloons". We made up an apparatus for calcining of raw material, and investigated the conditions for production of Silas Balloons, bubbling and expansive mineral component in Shirasu, the effectiveness of processing of raw material and producibility of Silas Balloons from some Shirasu produced in various districts, and measured general characteristics of Silas Balloons. And following results have been obtained. 1) Using the Shirasu as the material, it is optimum to calcine it at a temperature about 1000℃ shortly within 60 seconds. 2) Maximum size of calcining material is 300μ to obtain hollow glass microsphere. 3) It has been found that bubbling and expansive mineral component in the Shirasu is volcanic glass, and more accurately, the effective H_2O contained in it is estimated the bubbling agent. 4) Enriching the volcanic glass in the material through processing of raw material, especially through classification and magnetic separation, yield of Silas Balloons has considerably increased. 5) Some Shirasu produced in various districts would be able to be used as materials of Silas Balloons. 6) Compared with the known micro-sphere heretofore such as Microballoons of Emerson and Cuming Inc., Silas Balloons is superior to the former in its strength, melting point and hygroscopic property, though inferior to the former in its appearance.

Preparation of coated particles by an injection method was presented. The raw material of a coating layer is injected into a core particle suspension in which a precipitant is dissolved. By this method, some coated particles including titania hydrate-coated calcium carbonate powders and alumina hydrate-coated SiC whiskers were prepared. It was noticeable that CaCO_3, which is soluble in the raw material of titania hydrate, could be coated with titania hydrate. Furthermore, it was shown that aluminum nitrate and aluminum chloride as well as aluminum sulfate were useful as the raw material salts. Homogeneous nucleation and coalescence of the homogeneous nuclei onto the coating layers were expected to be included in the coating process.
