Alzheimer′s disease animal models were made by damaging bilateral nucleus basalis of Meynert of elderly rats (20-22 month) with quinolinic acid(150 nmol in 2 μL for each NBM, given d 3 after administration of test drugs). Activity of choline acetyltransferase was measured by radiochemistry assay. One time training passive avoidance step-down and water-maze spatial localization task were used to observe effects of ginsenoside of stem and leaf in combination with choline on learning and memory of AD model rats.

To sum up, the research for the first time ascertained INA species in apricot trees and their activities by using the rational method to imatate the temperature dropping process in frost nights--computer temperature controlling with semiconductor cooling and artificial frost box with self-recording. Studies were given to responds of INA to freezing temperature of floral organs, biochemical cold resistance parameters, contents of ABA and IAA, chlorophyll fluorescent parameters of young fruits and tissue structure and ultrastructure of apricot. The mechnism of INA induced frost injury of apricot was found out. And it was demonstrated that INA is a critical factor in the inducing and aggravation frost injury of apricot floral organs.
