Plasma Pharmacokinetics of Polyphenols in a Traditional Japanese Medicine, Jumihaidokuto, Which Suppresses Propionibacterium acnes-Induced Dermatitis in Rats.
Molecules 20 , 18031-46, (2015) Most orally administered polyphenols are metabolized, with very little absorbed as aglycones and/or unchanged forms. Metabolic and pharmacokinetic studies are therefore necessary to understand the pharmacological mechanisms of polyphenols. Jumihaidokuto (JHT)... |

Green tea catechins increase the force of contraction in isolated guinea pig atrial muscle preparations by increasing the amplitude of intracellular Ca2+ concentration.
J. Vet. Med. Sci. 74 , 1603-1608, (2012) It has been reported that green tea catechins enhance the force of contraction of isolated heart muscle preparations. However, it remains controversial whether or not the increase in force of contraction is related to an increase in the intracellular Ca(2+) c... |
