Abstract

The invention belongs to the technical field of animal model preparation, and particularly relates to preparation method of a spaceflight depression syndrome animal model. The method comprises the steps of S1, spaceflight depression syndrome model molding, namely adopting closed isolated culture, simulated weightlessness, noise and circadian rhythms to verify the condition of accepting simulated spaceflight stress stimulation of adult SD male rats; and S2, spaceflight depression syndrome model behavioristics evaluation, namely detecting a depression syndrome state condition through a sweet water preference experiment, an open field experiment, a Morris water maze experiment, a step-down experiment and a forced swimming experiment. According to the simulated weightlessness manner, a Chen Jie improved tail crane is adopted, and an angle of 30 degrees is formed between the body and the horizontal plane; for day and night rhythm change, day and night alternation of space flight in 90 minutes in a light and shade period is simulated through light control; and for the step-down experiment, an electrified copper grid is laid at the bottom of a reaction box, animals are shocked by electricshock, and for a normal reaction, the animals jump onto an insulating platform in the box to avoid harmful stimulation. Through model establishment, the influence of different conditions on the depression syndrome of an astronaut is studied.

Description

technical field [0001] The invention belongs to the technical field of animal model preparation, and in particular relates to a preparation method of an animal model of aerospace depression syndrome. Background technique [0002] In the process of space flight, astronauts face a special and complex space environment, including the influences caused by overweight, weightlessness, noise, vibration, shock, and curve acceleration of the vehicle and the spacecraft, and the internal and external environment of the spacecraft. The influence of factors, such as the small environment in the cabin, atmospheric pressure, harmful gases, radiation, meteors, meteorites, etc., all of these factors can affect the body and mind of the human body individually, comprehensively, indirectly or directly. These will increase the mental burden of astronauts to varying degrees and affect their physical and mental health. On the other hand, staying in space for a long time and monotonous and repetiti...
