  • The use of magnesium sulphate has recently increased in anesthesiology and pain medicine. The roles of magnesium sulphate are as an analgesic adjuvant, a vasodilator, a calcium channel blocker and reducing the anesthetic requirement. These effect are primarily based on the regulation of calcium influx into the cell and antagonism of the N-methyl-D-aspartate receptor. We discuss here the clinical effects of magnesium sulphate on anesthesiology and pain medicine.

  • Ginseng total saponins(GS), protopanaxadiol saponins(PD) and protopanaxadiol saponins(PT) antagonized the analgesia in mice induced by morphine. The administrations of 2,4-dihydroxyphenylalanine, and 5-hydroxytryptophan reduced the GS, PD and PT antagonisms of morphine analgesia. Possible mechanisms involved in the antagonistic actions of GS, PD and PT on morphine analgesia were described.

  • One bacterial strain, that had made the largest inhibition zone at the antagonism assay and also that lost the inhibition activity by the protease treatment, was isolated from raw milk. That strain was identified as Streptococcus salivarius subsp. thermophilus. The specific growht rate of this strain was maximum at 45$\circ $C. However, at this temperature the strain produced no bacteriocin. The bacteriocin activity was quite stable even at high temperature. Moreover, the activity of the vacteriocin was sensitive to proteases. but not to $\alpha $-amylase, DNase I, or RNase.

  • Several types of IFNs were tested for their ability to suppress TCDD-inducible P-450 dependent mixed function oxidase (MFO) system in mouse primary hepatocytes. Mouse IFN-gamma (IFN-G) markedly suppressed EROD activity when added at the same time as TCDD (10 nM). The antagonism of EROD activity by IFN-G exhibited both a dose-(10-100 U/ml) and time-depedence. In contrast, mouse IFN-A/B was only moderately suppressive and only at high concentrations (500 U/ml). Rat IFN-G was even more selective than mouse, wherase human IFN-G had no activity.

  • 비펩타이드성 안지오텐신 수용체 길항제로 새롭게 개발된 KR-31081은 재조합 수용체 결합실험에서 기존 의약인 로사탄에 비하여 8.6배 이상의 월등한 효과를 나타내었으며, 기능성 혈관실험에서도 대조물질인 로자탄보다 혈관수축 억제효과가 10배 이상 탁월하였다. 이러한 KR-31081의 특징들은 제 1형의 안지오텐신 수용체에 특이적으로 나타났으며 제 2형의 안지오텐신 수용체에 대한 수용체 결합친화력이 발견되지 않았다. 기능성 혈관실험에서는 KR-31081이 안지오텐신에 의한 혈관수축 효과를 경쟁적으로 저하시켰지만 표준물질인 로자탄과는 달리 농도가 증가함에 따라 혈관자체의 최고 수축효과의 감소가 관찰되었다. 안지오텐신 수용체에 선택적으로 작용하는 것으로 나타난 KR-31081은 고혈압 및 혈관질환에 대한 연구 및 진단에 활용될 수 있을 것이라고 판단된다.
