국소마취제의 약리학적 작용기전을 탐구키 위하여 소의 신선한 대뇌피질로부터 synaptosomal plasma membrane vesicles(SPMV)를 분리한 후 그 소수성 중심부의 microviscosity에 미치는 국소마취제의 영향을 pyrene 형광 probe법으로 측정한 결과 lidocaine HCI과 procaine HCI이 microviscosity를 낮춘다는 것을 알았고 그 정도는 procaine HCI에 비하여 tidocaine.HCI이 더욱 컸다. 또 국소마취 제 가 dimyristoylphosphatidylcholine (DMPC) multilamellar liposomes의 상전 이온도를 낮추며 cooperative unit크기를 감소시킨다는 것도... -

고양이 회장 종주근에서 세포막 소포를 분리하여 Na+의 농도 경사에 의존하여 일어나는 Ca2+ 이동의 특성에 대하여 연구하였다. 막소포 내부에서 외부로 향하는 Na+의 농도 경사 존재시 Ca2+의 축적이 현저히 증가하여 Na+ 의존성 Ca2+ 축적을 보였으며, 이는 외부용액에 Na+ ionophore인 monensin을 처리시 소실되었다. 한편 이러한 Ca2+ 축적의 증가 작용은 Na+에 특이적이었으며 K+, Li+, Rb+, Cs+ 및 choline이온은 Na+의 작용을 대치하지 못하였다. Ba2+, Sr2+, Mn2+ 및 Cd2+ 등의 2가 양이온들은 0.5 mM의 농도에서 Na+ 의존성 Ca2+...
