Abstract
The characteristics and differences between DMPP and McN-A-343 on the secretory effect of catecholamines(CA) were studied in the isolated perfused rat adrenal glands. DMPP(100 uM) and McN-A-343(100 uM) perfused into an adrenal vein of the gland casued significant increases in CA secretion. On molar basis the secretory effect of McN-A-343 was about one fifth as potent as that of DMPP. Tachyphylaxis to releasing effects of CA evoked by DMPP and McN-A-343 was not observed by repeated perfusion of these agents. The DMPP-evoked CA secretion was significantly inhibited by pretreatment with chlorisondamine, desipramine and profusion of
흰쥐 적출 부신에서 DMPP와 McN-A-343의 카테콜아민(CA) 분비작용의 차이와 특성에 대해서 연구한 결과 다음과 같다. DMPP(100 uM)와 McN-A-343(100 uM)은 부신정맥내로 투여시 유의한 카테콜아민 분비작용을 나타내었다. Mol농도로 비교시 McN-A-343의 CA분비작용은 DMPP의 약 1/5정도였다. DMPP나 McN-A-343의 반복투여시 반응 급강현상은 관찰할 수 없었다. DMPP의 CA분비작용은 chlorisondamine이나 desipramine또는
