Abstractprotection as well as inhibitory activities on xanthine oxidase, pancreatin, α-amylase, and angiotensin converting enzyme (Cho, 2005). Recently, it has been demonstrated that polyphenol compounds (PCRC), isolated from Bokboonja liquor, inhibits the CA secretory responses evoked by cholinergic (both muscarinic and nicotinic) stimulation as well as by direct membrane-depolarization from the isolated perfused adrenal gland of the normotensive rats (Kee and Lim, 2007) and spontaneously hypertensive rats (Yu et al., 2009). It seems that this inhibitory effect of PCRC is exerted by inhibiting both the Ca 2+ infl ux into the rat adrenal medullary chromaffi n cells and the uptake of Ca 2+ into the cytoplasmic calcium store partly through the increased NO production due to the activation of nitric oxide synthase (Kee and Lim, 2007;Yu et al., 2009).Generally, the presence of polyphenolic compounds isOriginal Article
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
