マグネシウム(Mg)は細胞内へのカルシウム(Ca)流入を抑制するCa拮抗物質で,インターロイキン6(IL-6)は臓器の侵襲程度を反映するサイトカインである。心筋梗塞症(AMI)急性期に硫酸Mgを投与し,再灌流障害を示唆する現象の抑制効果を検討した。再灌流療法施行患者連続22例を,再灌流療法前に硫酸Mg0.27mmol・kg-1を静脈内投与する群11例(Mg群)と非投与群11例(C群)とに無作為に割り付け,血中Mg2+濃度とIL-6を測定した。再灌流時の現象は再灌流不整脈,12誘導心電図上のST再上昇および胸痛の増悪とした。再灌流成功は20例(Mg群9例,C群11例)で,Mg群の平均血中Mg2+濃度は投与前0.39mmol・l-1から投与後1.04mmol・l-1に上昇した。再灌流不整脈の出現率はMg群がC群より有意に低く,ST再上昇度はMg群がC群より低い傾向にあった。血中IL-6ピーク値はMg群がC群より低かった。AMI急性期再灌流療法時の硫酸Mg投与は,虚血再灌流障害から心筋細胞を保護する可能性がある。

A 69-year-old female was found unconscious after nearly drowning (submersion) in a hot spring spa (Tamagawa spa, Akita prefecture) on June, 2001. The near drowning was associated with acid aspiration. She developed acute respiratory distress syndrome and shock after arrival at our emergency room. She was immediately treated using mechanical ventilation and percutaneous cardiopulmonary support. However, she died on the fourth hospital day as a result of a rapidly progressive lung injury induced by acid aspiration. Lung CT images demonstrated heterogeneous pulmonary infiltrations with irregularly fused cavities. An autopsy showed marked degeneration of the alveolar epithelium and abnormal deposits within the alveoli.

Pyrolysis infrared spectroscopy system using a pyrolysis probe has been developed for the rapid identification of waste rubbers containing a large amount of carbon black. This system consists of a pyrolysis probe, flexible and heatable gas guide, FT-IR, and computer. The small area of the surface of a plastic part is pyrolyzed momentarily with the pyrolysis probe, and the gaseous pyrolyzate is carried with nitrogen gas cell in FT-IR, the type of plastic is then identified with the IR spectra of the pyrolyzate. This method has the following features; (1) Almost all kinds of waste rubbers used for automobile parts can be identified in a few seconds. (2)Samples do not need to be carried. (3)Surface degradation and stains do not affect the identification. And (4) automatic identification system using this technique has made it possible to identify rubbers by only one action. The application of this method to the identification of weather-strips which had been collected from scrapped cars has confirmed that this method is useful for sorting before devulcanization process of waste rubbers.
