Embodiment 4:
New things distinguish that (Novel Object Recognition, NOR) experiment investigates Chinese herbal medicine extract and LPS is induced The new object resolving ability of learning memory injury mouse influence.
Material animal:ICR male mices, 18-22g;
Medicine:Lipopolysaccharides (lipopolysaccharide, LPS);Chinese herbal medicine extract;Doneppezil Hydrochloride;
Method:Chinese herbal medicine extract is prepared by the methods described of embodiment 1.ICR mouse are taken, 6 groups, every group 12 are randomly divided into Only:Blank control group, model comparison (LPS) group, Chinese herbal medicine extract group and positive controls (Doneppezil Hydrochloride).Each group is moved Thing fixing head after chloraldurate light anaesthesia, carries out intracerebroventricular injection.The basic, normal, high dosage of model group, Chinese herbal medicine extract Group (100,200,400mg/kg) and positive controls (donepezil 5mg/kg) injection LPS solution (5mg/ml, 3 μ l/ are only), it is empty White control group mice injects isometric physiological saline.From next day after lps injection, each Chinese herbal medicine extract administration group mouse root According to the solution that the daily gavage Chinese herbal medicine extract of the size of its body weight is made into, more than the daily gavage hydrochloric acid of mouse of positive controls how The neat solution of piperazine, the daily gavage of the mouse of blank group and model group gives isometric physiological saline.Proceed by new things within 8th day Experiment is distinguished, every preference index of mouse is determined.Computing formula is as follows:
As a result:In NOR experiments, intracerebroventricular injection LPS can make the mouse substantially reduce the preference index of new things.In Can substantially increase preference of the mouse to new things after herb extracts and positive drug Doneppezil Hydrochloride 5mg/kg treatments.Experiment Result shows that the Chinese herbal medicine extract can substantially increase the new object resolving ability of learning memory injury mouse of LPS inductions.
Embodiment 5:
Morris water maze laboratories investigate the learning memory injury mouse escape latency that Chinese herbal medicine extract is induced LPS Influence;
Material animal:ICR male mices, 18-22g;
Medicine:LPS;Chinese herbal medicine extract;Doneppezil Hydrochloride;
Method:ICR mouse are taken, 6 groups, every group 12 are randomly divided into:Blank control group, model comparison (LPS) group, Chinese herbal medicine Extract group and positive controls (Doneppezil Hydrochloride).Each group animal fixing head after chloraldurate light anaesthesia, is carried out Intracerebroventricular injection.Model group, Chinese herbal medicine extract basic, normal, high dosage group (100,200,400mg/kg) and positive controls are (more Donepezil 5mg/kg) injection LPS solution (5mg/ml, 3 μ l/ are only), blank control group mouse injects isometric physiological saline.From After lps injection from next day, size daily gavage Chinese herbal medicine extract of each Chinese herbal medicine extract administration group mouse according to its body weight The mouse of the solution being made into, the daily gavage Doneppezil Hydrochloride solution of mouse of positive controls, blank group and model group is daily Gavage gives isometric physiological saline.Proceed by Morris water maze laboratories within 10th day, continue 5 days.Mouse is determined fixed Escape latency in position navigation experiments experiment.
As a result:In Morris water maze laboratories, compare with blank group, LPS group mouse orientation navigation experiment the 5th day is escaped Keeping away incubation period substantially increases.Compare with LPS groups, Chinese herbal medicine extract group and positive drug Doneppezil Hydrochloride group were escaped at the 5th day Keeping away incubation period substantially reduces.Swimming rate of each group animal during testing is without significant difference.Test result indicate that, Chinese herbal medicine is carried Taking thing can be obviously improved the Spatial memory ability of learning memory injury mouse of LPS inductions.
Presently preferred embodiments of the present invention is the foregoing is only, is not intended to limit the invention, it is all in essence of the invention Any modification, equivalent and improvement made within god and principle etc., should be included within the scope of the present invention.
