最近は急性期の脳梗塞検体の染色を中心に行っております。梗塞巣の境界線は教科書通り明瞭でいつも感心します。LFB染色をすると写真で示すように、梗塞巣の白質はほとんど染まりません。でも染色後に顕微鏡で見ると白質の構造は保たれています。脂質顆粒細胞はまだ目立ちません。なぜ染色性がなくなるのか不思議です。
I have been focusing on staining cerebral infarction specimens in the acute phase. The edge of a focus is evident as in the textbook, and I am always impressed. As shown in the photograph, LFB staining hardly stains the white matter within the lesion. However, when I checked the specimen under a microscope after KB staining, the white matter structure tends to be maintained, and fat-granule cells are not yet noticeable. I wonder why the LFB stainability is lost.
