영어 초록

Acetylcholinesterase(AChE) is an enzyme which hydrolyses acetylcholine into choline and acetate. Glucose and Adenosine-5'-Triphosphate(ATP) are the primary energy source for the brain and therefore defects in glucose metabolism and the mitochondrial system can affect cognitive function. The fact that the level of acetylcholine(ACh), neurotransmitter, glucose and ATP, are found to be decreased in the brain of Alzheimer patients has lead us to focus on the inhibition of AChE for the developmental research of the Alzheimer's disease(AD) treatment. In this paper we describe the effects of herbal medicine 9908(滌痰化瘀湯加減) in vitro and in vivo. As herb 9908 concentraion increased, the Vmax values of AChE from Electric eel were decreased, which showed that the activity of AChE in vitro was decreased. Also herb 9908 inhibit AChE activity in vivo. When herb 9908 was orally administrated to rats, amount of glucose and ATP which are energy source in metabolism, increase in brain and blood of rats. These result are also interesting in their effects for AD treatment compare with comercial drugs such as Cognex and Aricept. Furthermore, when considering the toxic problems of the Cognex and the Aricept, these oriental medicines could be very valuable medicine for treatment of AD. Abbreviation AD: Alzhemer's disease, AChE: acetylcholinesterase, ACh: acetylcholine, ATCh: acetylthiocholine, DTNB: 5,5‘-dithio-bis-2-nitrobenzoate, ATP: Adenosine-5'-triphosphate GAPD: Glyceraldehydephosphate dehydrogenase PGK : phosphoglycerate phosphokinase
