側副血行による左心拡大を呈した高令女性の肝部下大静脈閉塞症の1例を報告した.特記すべき家族歴既往歴はなく, 67才検診でX線像上心陰影拡大と肝機能異常を指摘され,外来通院中,肝シンチで肝形態異常を認め精査のため入院.現症で浮腫・腹水・腹壁静脈怒張なく,内視鏡で食道静脈瘤も認めない.画像検査では尾状葉腫大を認め腹腔鏡・肝生検では肝硬変を確認,血管造影で著しい門脈下大静脈シャントと,下大静脈から脊椎を横切り心臓の左外側に上行する太い異常側副血行を見出し,静脈撮影で肝部下大静脈膜様閉塞症(Budd-Chiari症候群)と診断した.多彩で著明な側副血行と乏しい自他覚所見から早期からの側副血行形成が推測された.

Blue Laser Diodes Fabricated onm-Plane GaN Substrates

Blue laser diodes (LDs) were fabricated on m-plane oriented GaN substrates by atmospheric-pressure metalorganic chemical vapor deposition. Typical threshold current for stimulated emission at a wavelength λ of 463 nm was 69 mA. Blueshift of the spontaneous emission peak with increasing injection current was examined in LDs fabricated on m- and c-plane GaN substrates. Blueshifts for the m-plane LD (λ=463 nm) and the c-plane LD (λ=454 nm) with an injection current density just below threshold were about 10 and 26 nm, respectively. These results confirm that the blueshift in quantum-wells fabricated on m-plane oriented substrates is smaller than on c-plane oriented substrates due to the absence of polarization-induced electric fields.
