ln order to investigate pharmacological properties of New Woohwangchungsimwon Liquid (NCL) and Woohwangchungsimwon Liquid (CL), effects of NCL and CL on cerebral ischemia and central nervous system were compared. Cerebral ischemia insult was performed using unilateral carotid artery occlusion in Mongolian gerbils. The histological observations showed a preventive effect of NCL and CL treatments with ischemia-induced brain damage. The ATP in brain tissue was decreased in vehicle-treated ischemic gerbils. This decrease was prevented by CL treatment. In contrast to what was seen with ATP, the lactate and lipid peroxide were both elevated in vehicle-treated ischemic gerbils. This elevation was inhibited by NCL and CL treatments. While NCL and CL had no effects on the hexobarbital-induced sleeping time, they prevented the seizures induced by electric shock and pentetrazol. NCL and CL showed sedative effect in rotarod and spontaneous activity test. Respiration rate and depth were increased at the high dose of NCL and CL. Furthermore, NCL and CL showed anti-stress effect. Our findings suggest that the pharmacological profile of NCL on cerebral ischemia and central nervous system are similar to that of CL.
