Hypokalemic myopathy has been observed in various clinical conditions. There are many studies of the pathomorphological changes of muscle fibers but alterations in intramuscular nerves and motor end-plates are seldom mentioned. The present authors observed biopsied muscle from a 51-year-old housewife who had suffered from gradually increasing muscle weakness. Laboratory examinations revealed a severe hypokalemia of 1.5 mEq/1, 18304 U/1 of CPK, 1300 U/1 of LDH, 343 U/1 of SGOT and 297 IU/1 of adolase. Light-microscopic examination showed changes previously described, including twin-peaked distribution in the histogram of type I, IIA and IIB fibers, ballooning and thickening of terminal axon, and 2 or 3 end-plates closely spaced along the length of muscle fibers. The electron-microscopic examination revealed empty folds of basement membrane in end-plate regions, reduced secondary synaptic clefts, interposition of Schwann cell processes between nerve ending and primary synaptic cleft, and an increase of disarranged microtubules and neurofilaments in terminal axons. The findings suggest that severe hypokalemia primarily produces structural alterations of intramuscular peripheral nerves and motor end-plates as well as of muscle fibers.

酵母様真菌の一つであるカンジダは口腔や膣などの常在菌であるが, 日和見感染として内臓諸臓器に膿瘍を形成することがある.この膿瘍内でのカンジダ形態の観察には, 組織標本よりも塗抹標本の方が優れていることを播種性深在性カンジダ症の2剖検例を用いて報告した.症例1は急性骨髄性白血病の再燃例で剖検では肺, 肝, 腎, 脾にカンジダ膿瘍が, 左心内膜にはカンジダ疵贅が認められた.症例2は急性心筋梗塞後の昏睡例で, 剖検で両側の腎と左心室前壁にカンジダ膿瘍が認められた.2例ともに膿瘍の組織標本ではカンジダが密に増殖していたり, 炎症細胞に囲まれていて, 真菌形態を観察しづらかったが, 塗抹標本ではカンジダに特徴的な仮性菌糸と出芽分生子が明瞭に観察できた.塗抹標本は新鮮材料からとホルマリン固定後の膿瘍組織から作製したものを比較したが, いずれでもカンジダ形態の観察は組織標本よりも容易だった.ホルマリン固定にかかわらず, 膿瘍の塗抹標本をつくることは有用であると考えられた.

脾カンジダ症を伴った気管支肺アスペルギルス症の1剖検例を報告し, それを用いて, 内臓真菌症の中でも原因菌属としてカンジダに次いで最も多いアスペルギルスの同定を, 菌糸のみの形態的特徴から試みた.症例は43歳, 女性. 急性前骨髄球性白血病の再燃例で右肺中・下葉および左上葉にアスペルギルスによる肺炎をきたし, 右中・下葉の一部は横隔膜に癒着し, 右出血性胸膜炎を呈していた.左上葉では空洞を形成していた. 脾には結節状のカンジダ感染が認められた. 剖検時に右肺・横隔膜癒着部および左上葉空洞内の壊死物の塗抹標本を作製したところ, アスペルギルスの菌糸の特徴すなわち, Y字状に2分岐しながら一方向へ向かって増殖するようすがきわめて明瞭に見い出され, 組織標本で観察できた菌糸形態よりも真菌の同定に役立つと考えられた.
