The invention relates to an automated mechanical arm stimulating device for an animal memory training system, which fundamentally solves the problems of excessive anthropic factor involvement and untimely and inaccurate stimulation of a stimulating system in the traditional maze device. The automated mechanical arm stimulating device comprises an orthogonal coordinate robot positioning system, a PLC (Programmable Logic Controller) system, a test mouse position detecting system and a stimulating system, wherein the orthogonal coordinate robot positioning system is established by adopting a rapid linear positioning mechanism; the test mouse position detecting system comprises four photoelectric thru-beam sensors which are respectively arranged at the door openings of the animal memory training system; the stimulating system comprises a mechanical arm with three pipelines; and the three pipelines respectively correspond to water, gas and food stimulation and respectively realize the supply of water, gas and foods by the PLC system. The automated mechanical arm stimulating device is used for more timely and accurately stimulating a test animal by matching with the animal memory training system formed by a closed rotary maze and ensures the test effect of the animal memory training system.

The invention discloses an anti-influenza virus or anti-inflammatory drug screening model based on living lung slices, which is characterized in that it comprises the following steps: first infecting the living lung slices with the virus, and then applying the drug to be tested to the virus-infected Live lung slices, and finally verify the effect of the drug to be tested by detecting changes in virus titers and related cytokines. The invention also discloses a method for constructing the screening model, which includes: preparation of lung slices, optimization of thickness of lung slices, evaluation of the correlation between neuraminidase activity and virus titer, and selection of inflammatory factors. Through this invention, a drug screening method based on living lung slices is constructed, which is more accurate and effective than traditional cell models in line with real body conditions.

The invention discloses a multifunctional wooden table. The multifunctional wooden table comprises a bottom cabinet, a storage cabinet, balance columns and a main table surface, wherein the storage cabinet is arranged above the bottom cabinet; the bottom ends of the four balance columns are arranged on the four corners of the upper surface of the storage cabinet; the heights of the balance columnscan be randomly adjusted; and the top ends of the four balance columns are arranged on the four corners of the lower surface of the main table surface. According to the multifunctional wooden table,the balance of the main table surface can be freely adjusted through the arrangement of the balance columns, so that the main table surface meets the experiment requirements; due to an additionally arranged movable table surface, the area of the table surface can be expanded, more physical instruments can be placed, and the experiment operation is facilitated; and when the excessive physical instruments do not need to be placed, the movable table surface can be stored in a storage groove, so that the occupied area of a physical instrument experiment table is reduced, and the space is saved.

The invention discloses a method for putting coal at the bottom of a two-dimensional similar material test bench. The specific steps are as follows: S1: Connect the fixing holes on the front and rear sides of the bottom of the two-dimensional similar material test bench with support brackets, and place between the two support brackets Install multiple sets of coal discharge turning devices, and then lock the locking device; S2: The channel steels are respectively located on the corresponding support brackets, and the experimental similar materials are placed on the coal discharging turning devices; S3: Wait for the similar experimental materials to solidify and then remove the front groove Steel, excavate a coal seam of a certain width at one end of the two-dimensional similar material test bench, and then seal the front side of the similar material for the test with transparent plexiglass; S4: Open the locking device, and use a wrench to lock it on the rotating shaft in the coal turning device Coal discharge steel plate, the coal discharge steel plate of this application can control the size of the coal discharge opening, and can be closed immediately and quickly after coal discharge, thus effectively preventing the lateral leakage of top rock model debris and ensuring the experimental effect.

The invention discloses a thermostatic impregnation device used for a laboratory. The thermostatic impregnation device comprises a thermostatic oven and a rotary drum, wherein a left rotating shaft and a right rotating shaft are respectively and fixedly arranged at two ends of the rotary drum and rotatably connected with a support; the rotary drum and the support are arranged inside the thermostatic oven; the support is connected with and fixedly arranged at the bottom part of the thermostatic oven; the right rotating shaft penetrates through the side wall of the thermostatic oven and is rotatably connected with the side wall of the thermostatic oven; the right end of the right rotating shaft is fixedly connected with the output shaft of a motor; and the motor is fixedly arranged on and connected with the side wall of the thermostatic oven. When an impregnation experiment is performed, a sealed impregnation container filled with an impregnation solution is fixedly arranged inside the rotary drum; the door of the thermostatic oven is closed; the temperature of the interior of the thermostatic oven is set; the motor is started and drives the rotary drum arranged in the thermostatic oven to rotate; thus, the impregnation solution can be experimented under the conditions of a constant temperature and continuous and uniform shaking, so experimental effects can be effectively guaranteed, and the accuracy of experimental data is improved.
