【背景】我が国では年間約5万人が新たに植込み型心臓デバイス(CID)植込み治療を受けているが,死後,火葬時の取り扱いについては一定の見解がない.CIDを取り出さずに火葬可能であれば,安心してCID植込み患者を自宅で看取ることができる.【目的および方法】火葬時のCIDの取り扱いについて,中国地方の現状を調べるため,中国地方5県(鳥取・島根・岡山・広島・山口)の162火葬場の管理者(76事業所)に,火葬時の取り扱いについて電子メール・ファックス・電話で調査した.【結果】摘出なしでは火葬不可が8事業所9ヵ所(5.6%),病院で亡くなる場合などでは可能な限り摘出を希望するが,事前の申請があれば摘出なしでも火葬可が42事業所93ヵ所(57.4%),事前の申請があれば摘出なしでも火葬可が27事業所60ヵ所(37.0%)であった.【結論】火葬時の事前申請は必要であるが,中国地方では94.4%の火葬場でCIDを摘出しなくとも火葬が可能であった.(心電図,2019;39:33~38)

Abundant copper vein deposits of the mine occur in the Itaya formation composed of sandstone and intercalating shalebeds of the Miocene Miyai group. Principal ore mineral is chalcopyrite, and it is associated with pyrite, sphalerite, galena, quartz, calcite, chlorite, sericite, etc. Chloritization, silicification and sericitization of wall rocks are very distinct. Vein fissures of the mining district can be grouped in three sets of strike direction: N-S, E-W and NW-SE groups. Fissures of N-S and E-W group are shear fractures, while those of NW-SE group are tension cracks. The ore-bearing veins of the E-W and NW-SE groups have been mined chiefly for copper ore. Fissures of the N-S group contain a large amount of pyrite but are rather barren of chalcopyrite.Depth zone that comprises the workable extent and ore shoots of each veins is remarkably limited within the sandstone-rich members of the Itaya formation.Th0e Miyai group surrounding the main ore-bearing area has general strike of N20-4°E and dips 10-30°eastward. The main ore-bearing area is situated in a, dome within the northwestern part of a large basin of the. Miyai group. The long axis of the dome is orientated parallel to the general strike of the Miyai group. The ore-bearing area is divided into four districts by the difference of local structures: northeastern, northwestern, southeastern and southwestern districts. Structural and mineralogical features of ore-bearing fissures in each district reflect the difference of geologic structure. A notable difference is that the fissures in the northeastern district run at nearly right angles to the strike of the strata, while those in the southwestern district are parallel to them.Four stages of mineralization can be recognized: the first stage (Cu-Py), the second (Pb-Zn), the third (Au-Ag) and the fourth (calcite).Distribution of the metals deposited in the area are expressed as assay grade multiplied by the width of veins, and iso-metal quantity contours are illustrated on the maps. It seems possible that mineralization centers of each four stages overlap one after another in the southwestern district, while no evidence of coincidence is observed in the northeastern district. Fissures of the N-S group can be regarded as the channelways of mineralizing solutions.Cu and Pb-Zn zones can be depicted successively outwards from centers where two sets of fissures of the N-S group and the E-W or NW-SE group cross each other. These features might be useful for further exploration.

The copper deposits, consisting of chalcopyrite, pyrite, sphalerite, galena, quartz, calcite, sericite and others, in the main area of the Kishu Mine occur in the Okochi 'the Itaya and the Taketo formations of the Miocene Miyai Group. They are mainly composed of sandstone, and sandstone and shale.The Miyai Group surrounding the main ore-bearing area has a general strike of N20-40°E and a dip of 10-30°E. The main ore-bearing area is situated in a dome of a large basin of the Miyai. Group. The long axis of the dome is parallel to the general strike of the Miyai Group.Vein fissures of the main mining district are grouped in the following three sets according to the strike directions: i. e N-S, E-W and NW-SE. Intersections between two sets of fissures of the N-S group and the E-W or NW-SE group, can be regarded as the channelways of mineralizing solutions and mineralization centers. The most important intersection is situated in the vicinity of the dome where Josen No. 20 vein meets Josen 9-level North Cross-cut.Five mineralization stages can be recognized. i.e Py, Cu-Py, Pb-Zn, Au-Ag and calcite stages. There are two types of copper ores. The one is associated with chlorite formed during the Cu-Py stage and the other with sericite formed during the Pb-Zn stage. The latter's deposition centers are generally beneath the former's.Silicification, chloritization and sericitization are recongnized as wall-rock alterations.The Cl- content distribution in the deep seated ground-water in the mine well reflects in the geologic structure.Filling temperatures of the minerals mainly measured by decrepitation method are 172-318°C in chalcopyrite, and 160-330°C in pyrite.
