There are various perspectives on the roles and functions of museums. In modern times, socio-educational functions of museums are the most emphasized. Most museums offer programs for schools, but teachers still prefer not to visit them. The reason why teachers feel pressured to visit a museum is that they lack knowledge about museum exhibits. Also, it takes too much time and energy for individual teachers to reconstruct the curriculum in conjunction with museum exhibits. The link with the school... -

Lithium (Li) is known to be used not only during acute manic psychosis but also acute depressive phase in manic-depression. In the present study, it was attempted to investigate the effect of lithium on catecholamine (CA) secretion from the isolated perfused rat adrenal gland and to clarify the mechanism of its action. Replacement of Na+ (118.4 mM) by lithium in the normal Krebs-bicarbonate solution used to perfuse the gland produced gradually an increased response in the spontaneous... -

흰쥐 관류부신에서 histamine의 catecholamine (CA) 분비작용의 특성과 기전을 규명코자 연구한 결과는 다음과 같다. Histamine (37.5 ~ 150μg)을 부신정맥내에 주사 하였을 때 현저한 용량 의존성의 CA 분비작용을 나타내었다. 그러나 histamine (150μg)을 120분 간격으로 반복 투여시 제 3차 투여시부터는 CA 분비효과가 뚜렷이 감소하였다. 즉, histamine의 반복투여로 인한 반응급강현상을 관찰할 수 있었다. Histamine의 CA 분비작용은 chlorisondamine, diphenhydrarmine, ranitidine, Ca++-free Krebs 용액의 관류, nicardipine...
