Research Abstract

Endogenous digitalis-like factor(EDLF) exist in the central nerve system as well as peripheral tissue. Ouabain is existed in hypothalamus and regulated by renin angiotensin aldosterone system(RAAS). A novel EDLF belonged to bufadienolide may be secreted from hypothalamus immortalized cell line. Moreover angiotensin should regulate to secret marinobufagenin and marinobufotoxin from adrenal gland.
