新生児低酸素性虚血性脳症の動物モデルとして、新生仔豚を対象に負荷時の脳血液量を指標とした低酸素負荷を行い、低体温療法、ラジカルスカベンジャー(エダラボン)と低体温併用療法の効果、および水素ガス吸入療法の安全性の検討を行った。その結果、無治療の蘇生後24時間での脳血液量増加と低振幅脳波持続時間は正の相関を示したが、低体温療法では負の相関を示した。また低体温療法と併用療法は無治療と比較し、大脳皮質および白質障害は少なかったが、低体温療法のみと併用療法は中枢組織障害の差異は認めなかった。さらに水素ガス吸入は、体・脳循環、脳波及び血液ガスへの影響がなく、その使用上の安全性が確認された。

The effect of the addition of light anhydrous silicic acid to potato starch powdes, which improves the lubricating characteristics of drug powders, is usually cancelled by the absorption of moisture. In order to improve this point, hydrophobic light anhydrous silicic acid was used, and prevention of the loss of the lubricating effect by moisture sorption was examined.1) Moisture sorption of the mixture of dry starch and silicic acid (0.1%) results in the increase of the apparent specific volume and angle of repose, and decrease of dispersibility, with the increase in water content. The resultant mixture shows powder characteristics close to that of starch, that is the lubricating effect of light anhydrous silicic acid is lost. When 0.1% hydrophobic silicic acid is added, its effect was almost the same as when added to moistened starch, and the lubricating effect of hydrophobic silicic acid was not lost due to moisture sorption by starch.2)Examination of such mixtures by a scanning electron microscope revealed that ordinary light anhydrous silicic acid stuck to starch granules that looked like the moistened thin paper to be stuck when light anhydrous silicic acid experienced moisture sorption, and light anhydrous silicic acid could not prevent the contact of the starch granules. This resulted in the reappearance of powder characteristics in starch itself. In the case of hydrophobic light anhydrous silicic acid, the particles do not stick to or fall from starch granules even after moisture sorption and remain attached sterically to the starch granules the same as after their addition, and prevent the contact of starch granules themselves. This is considered to be one of the reasons why hydrophobic light anhydrous silicic acid does not lose its lubricating effect.

Pharmaceutical preparations such as sodium bicarbonate, lactose and potato starch show 2 different physical properties depending on their crystal diameters and moisture contents. Light anhydrous silicic acid (LASA) was added in several levels to 2 forms of the above preparations in order to investigate how these amounts of addition cause differences in their physical properties. Results are as follows:1) The angle of repose was minimized when LASA was added to powdered sodium bicarbonate in a proportion ranging from 0.1 to 0.25% and became greater in proportions exceeding 0.25%. Both the angle of repose and apparent specific volume of crystalline sodium bicarbonate were minimized by addition of LASA 0.01% and became greater in proportions exceeding 0.5%.2) In the case of powdered lactose, addition of LASA 0.01%resulted in negligible improvement in the physical properties. The effect was maximum in the proportion of 0.25%. In the case of crystalline lactose, addition of LASA even in 0.01% improved the physical properties. The effect was slightly enhanced by addition of LASA up to 0.1%. However, the addition of LASA in the proportion ranging from 0.25 to 0.5% deteriorated the effect.3) The degree of improvement in the physical properties of wet and dry potato starch reached maximum by addition of LASA 0.25 and 0.05%, respectively. The effect on wet stacrch by addition of LASA was greater.4) Scanning electron microscopy for observing the mixed conditions revealed that larger number of LASA particles attached to particles of the preparations when the physical properties were improved to a greater extent, and further increased proportions of addition resulted in the tendency to deteriorate physical properties by generation of aggregated particles of LASA attached particles of the preparations.

ALI/ARDSの予後は改善してきており,その主因は肺保護的換気モードの周知による.現在,死因は呼吸不全ではなく,多臓器不全がほとんどである.ICU重症患者の予後予測法で普及しているのは,米国ではAPACHE IVであるが,本邦ではSOFAとAPACHE IIである.現在,ヨーロッパを中心にSAPS 3を用いた研究が進行中である.生物学的マーカーは複合した方が予後予測精度はよく,単独ではIL-8とSP-Dが比較的有用である.重症度スコアリングはベンチマークを通して医療の質向上に役立つ.
