EST is a specific thiol protease inhibitor newly synthesized as a drug for muscular dystrophy.Following the first Phase I study of EST single dose (First report), the second Phase I study on EST continuous administration was performed in healthy adult male volunteers to investigate its safety and pharmacokinetics.In the first stage, 100mg was administered 3 times a day after meals for 1 day, and in the next stage, 100 mg was administered 3 times a day after meals for 7 consecutive days.No change due to EST was found from the observation of the subjective and objective symptoms and clinical tests.EST was detected as E-64-c (effective form of EST) in serum and urine after oral administration. No accumulation of EST was observed after continuous administration, and approximately 30% of total EST was collected in urine.

指尖容積脈波のデジタル処理解析による交感・副交感神経機能検査法を用いて慢性腎不全患者の自律神経機能を検討した. 対象は慢性腎炎 (62例), 嚢胞腎 (3例), 腎盂腎炎 (2例), 痛風腎 (1例) 由来の慢性腎不全68例 (非透析群17例, 血液透析群30例, CAPD群18例, 腎移植群3例) で, 糖尿病, SLE等の全身性疾患による腎不全例は除外した. 指尖容積脈波は安静臥位で非シャント側, 第2指より2分間連続記録, デジタル処理解析し, 脈波波高変動係数 (CVWH), 脈拍間隔変動係数 (CVPP) を算出した.CVWH, CVPPはそれぞれ腎不全群7.44±3.58, 2.41±0.94, 非透析群7.92±3.68, 2.88±0.94, 血液透析群7.57±4.04, 2.29±0.76, CAPD群6.69±2.96, 1.96±0.83, 腎移植群8.20±1.92, 3.70±1.32であった. CVWHは健常群に比して腎不全各群で有意の低下を示し, CVPPは非透析群では健常群との間に有意差はないものの低値を示す例が多く認められた. 透析群では明らかに有意の低下を示した. また, 透析法別にみた群間比較に有意差を認めなかった. CVWHとCVPPの関係を見ると腎不全例, 透析例で有意の相関を認めた.以上より, 今回検討した慢性腎不全例のCVWH, CVPPは共に低下し, 交感・副交感神経機能に障害を認めた. 非透析群間に差を認めなかったことから, 腎不全で認められる自律神経障害は透析療法では改善困難であると考えられた. また, 腎不全群と透析群のCVWHとCVPPとに相関が認められたことより交感・副交感神経が同時に障害されることが推察された.

Whole blood viscosity, RBC defomability index and fibrinogen in ischemic cerebrovascular disease

虚血性脳梗塞98例について全血粘度, 赤血球変形能, 血漿フィブリノーゲン (以下fbg.) を測定しその臨床的意義を検討した.対象症例は臨床像 (特にCTおよび血管写所見) より皮質枝梗塞38例, 穿通枝梗塞60例の二群に分け, さらに急性期, 慢性期に分類して検討した. (1) 脳梗塞例のヘマトクリット (以下Ht) 補正全血粘度は対象群に比し有意に高値を呈した. (p<0.01) (2) 脳梗塞例の赤血球変形能も対照群に比し有意の低下を認めた. (3) 急性期脳梗塞の血漿fbg.は有意に高値を示すことが認められた.したがって脳梗塞の全血粘度の上昇は単にHtの上昇のみによるものでないことが明かとなった. (4) 皮質枝および穿通枝梗塞の2群間には全血粘度, 赤血球変形能ともに有意差は認められなかった. (5) 急性脳梗塞例では皮質枝, 穿通枝両群とも全血粘度の上昇する傾向が認められた.

Local cerebral blood flow measurements by xenon enhanced computer assisted tomography

Keizo Toyohara; Ryoich Toshima; Takashi Joich; Sadatomo Shimojo; Tadashi Miyahara

Xenon CT法により局所脳血流量 (LCBF) を測定し, その問題点と方法論を検討した.対象は健康成人7例, 脳梗塞9例である.使用Xenon gas濃度はXenonエンハンス率やS/N比, 麻酔作用等の問題を考慮すると, 50%が至適である.非侵襲的なLCBF測定を行うために, 比較的短時間Xenon吸入法を考案した.すなわちscanning intervalを初期には1分毎に, 以降3分前後とし, 全吸入時間を6分から15分に設定して比較検討した.さらにscan dataをautoradiography法を改変した指数関数curve fitting法により処理した.その結果基底核, 視床においては, Xenon 6分吸入曲線から臨床応用が可能なLCBFを得ることができた.この方法により健常例の基底核におけるCBFの平均値は, 85.7±19.3ml/100g/minであり, 飽和曲線から得た平均94.8±17.4mlとほぼ一致した.LCBFの計算処理方法に関し, scannerの性能, radiation dose等から, Xenonの飽和曲線を用いたautoradiography法が至適であると思われる.
