Embodiment 1

[0110] Construction of Alzheimer's disease model in juvenile zebrafish

[0111] 1.1 Experimental materials

[0112] Aluminum chloride, produced by Shanghai Aladdin Company. Healthy juvenile zebrafish (3 days old) were provided by the Institute of Biology, Shandong Academy of Sciences, and strictly followed the relevant processing guidelines of the International Laboratory Animal Protection Certification and Evaluation Agency.

[0113] 1.2 Experimental method

[0114] 1.1.1 Experiment preparation:

[0115] Select 3-day-old zebrafish juveniles and divide them into eight groups randomly, with 30 fish in each group. Place the eight groups of fish in a 24-well cell culture plate (8 to 12 fish in each well), and keep the pH at 7.0 to 7.5. The water environment was kept in a constant temperature incubator with an ambient temperature of 28.5°C, and it was always maintained in an alternating day and night environment with 10 hours of light and 14 hours of shading.

Abstract

The invention discloses an anti-Alzheimer's disease drug screening method based on behavior and biochemical indicators and a drug screened by the method. The screening method comprises the steps that a zebra fish juvenile fish Alzheimer's disease model is built, the maximum safe concentration of a drug to be screened is determined, and experimental treatment is conducted on zebra fish juvenile fish; the method also includes screening an anti-Alzheimer's disease drug by utilizing behavioral and biochemical indexes; and judging whether the medicine has the Alzheimer's disease resistance or not. According to the anti-Alzheimer's disease drug screening method based on behavior and biochemical indicators, the anti-Alzheimer's disease drug can be systematically and completely screened, especially, new drugs with uncertain efficacy are screened; compared with the prior art, medicine soaking and testing environments are simpler and only need to be carried out in the experimental pore plate, multiple fishes can be soaked in medicine in one pore during medicine soaking, the behavior ability of 48 fishes can be tested at most at the same time during testing, the operation process is simple and easy to operate, the testing workload is greatly reduced, and testing system errors are reduced.

Description

technical field [0001] The invention relates to the technical field of drug screening, in particular to a screening method for anti-Alzheimer's disease drugs based on behavioral and biochemical indicators and the drug screened by the method. Background technique [0002] Alzheimer's disease is the most common neurodegenerative disease that plagues middle-aged and elderly people. Memory and cognitive dysfunction are the core features of the disease. decline, unresponsiveness, and even personality changes that progress to a state of general dementia. The main neuropathological features of Alzheimer's disease are hyperphosphorylated tau protein aggregation leading to intracellular neurofibrillary tangles; abnormal accumulation of β-amyloid protein to form extracellular amyloid plaque; due to excessive aggregation of abnormal proteins in brain regions, It affects and even apoptosis brain cells, forming the typical neuropathological damage of Alzheimer's disease patients. On th...
