18年の長期経過をたどった気管支内異物による反応性肉芽腫の一例を経験した.症例は25歳男性.健康診断の胸部X線写真で,右下肺野の帯状影を指摘された.気管支鏡検査で右B^<9+10>を閉塞する腫瘤を認めた.生検で肉芽腫と診断.腫瘤の末梢側の観察が不可能で悪性疾患の合併も否定出来ず,開胸術で腫瘤を摘出した.腫瘤は有茎性ポリープ様で炎症性肉芽腫と診断した.術後8日目の胸部X線写真で術前と同様の無気肺が出現,気管支鏡検査でも術前と同様に腫瘤を認めた.生検鉗子で肉芽腫を可及的に摘出すると,開存したB^<10b>に3.0×2.0cm大のビニール片を認めこれを摘出した.以後,肉芽腫の再発は認めていない.仔細に問診すると,7歳時のパン食い競争後に強い咳嗽,胸痛を自覚していた.今回の気管支内異物は,この際誤嚥したビニール片と考えられこの異物による物理的刺激が反応性肉芽腫の成因と推察された.

Three polymorphs of Al2SiO5, andalusite, kyanite and sillimanite, occur in contact with each other, forming aggregates in a part of the Nishidohira pelitic metamorphics in the Hitachi area of the southernmost Abukuma Plateau. Textural relationships between the three polymorphs suggest that andalusite formed first probably as chiastolitic porphyroblasts, that kyanite and/or sillimanite grew subsequently at the expense of pre-existing andalusite, and that sillimanite continued to form even in the rock matrix thereafter. The andalusite-forming first stage may have been either a contact metamorphic event by unknown plutons or a regional metamorphic event of low-pressure type. The second kyanite and/or sillimanite-producing stage was induced by high-temperature loading, whereas the third sillimanite-forming stage possibly resulted from the contact metamorphism by the Nishidohira gabbroic intrusion exposed near Hase. Well-preserved growth zoning of garnet containing sillimanite inclusions in the andalusite-kyanite-sillimanite-bearing gneisses also indicates the high-temperature compression. The loading may be attributed to the overthrusting of the nearby Hitachi metamorphics onto the Nishidohira metamorphics. Such a P-T path of the Nishidohira metamorphics is similar to that of the Takanuki metamorphics in the central to southern part of the Abukuma Plateau. The widespread occurrence of texturally sector-zoned garnet in pelitic-psammitic rocks and the inferred short duration of high-temperature conditions are also in common to the Nishidohira metamorphics and the Takanuki metamorphics.

Fossil rodents, represented by nine isolated teeth, were obtained by wet sieving sediments from the Upper Pliocene Tsubusagawa Formation in Ajimu, Oita Prefecture. The rodent remains include Micromys sp., Arvicolinae gen. et sp. indet., and unidentified incisors. This is the first report of the Pliocene rodent fauna in Japan. Micromys sp. fossils differ from modern species in occlusal outline, number of roots, crown size, position of t4 and t6, size of t9, and presence or absence of t7 in the upper M1. Arvicorinae gen. et sp. indet. have such features as a hypsodont, very high sinuous line, thick cementum, and relatively wide crown in comparison to other arvicolids. Historically, Micromys and Arvicolinae have had a Palearctic distribution. This is consistent with previous plant fossil research that indicates a temperate-zone climate in the lower to middle part of the Tsubusagawa Formation. However, it is not consistent with the fossil tortoise and large mammals included in the Ajimu Fauna, which represent a subtropical or tropical This contradiction may suggest that the fossil assemblage was formed in an environment under the transition from tropical to temperate zone in the gradually cooling climate of the Late Pliocene.

症例は74歳男性.1期肺腺癌術後肝転移に対し,rhG-CSF併用chemotherapy(MVP療法:CDDP80mg/m^2,VDS3mg/m^2,MMC8mg/m^2,2週間隔,5クール)で画像上PR(PertialResponse)を得た.化療中のCEA値を経時的に測定した結果,腫瘍体積と有意の相関をみた.画像上PRであったがCEA値は完全に正常化した.このことは,縮小した塊状影が腫瘍の壊死組織である可能性を示している.本症例の血清CEA値は,予後判定のうえで再発の指標となり,抗腫瘍効果のマーカーとして鋭敏に反応した.血清CEA値は画像診断の限界を補う新たな化療効果判定方法になりうることが示唆された.
