Reproduction method: Adult rats were gavaged with 4 ℃ vinegar daily, with a volume of 10ml/kg body weight for 10 consecutive days. During this period, observe changes in animal appearance and behavior, weight, food intake, and water intake. On the da...
2023-09-12Reproduction method: Adult rats were raised in a single cage and subjected to external abdominal irradiation at a dose of 250 rad/min. The first dose was followed by a second dose of enhancement 7 days after the first dose. The changes in food intake...
2023-09-12Toll like receptor 2 gene knockout mice. In Toll like receptor 2 gene knockout mice, homozygotes can survive with normal appearance and behavior. Macrophages from mouse bone marrow cannot stimulate immune responses to lipoproteins of Borrelia burgdor...
2023-09-12Reproduction method: Adult rats were raised in a single cage, and the experimental rat cage was fixed to the oscillator using a tray. The oscillator was controlled by a relay to stop for 10 minutes every 20 minutes of vibration, with an average of 10...
2023-09-12The homozygous CD4 antigen knockout mice cannot express CD4 on the cell surface. CD8+T cells and myeloid components develop normally. This indicates that expression in ancestral cells and CD4+CD8+thymocytes is not necessary. The antiviral activity of...
2023-09-12Reproduction method: Adult rats were raised in a single cage and given a sufficient amount of medicated feed (rhubarb, mirabilite, and standard feed materials were evenly mixed in a ratio of 0.85:0.15:9.0 to make medicated feed, with 0.1g of raw medi...
2023-09-12Gene knockout mice with B cell defects. In B cell deficient Igh-6 gene knockout mice, homozygotes lack mature B cells and cannot express membrane bound IgM. This mouse is mainly used to study the function of B cells in the immune system. For example,...
2023-09-12Reproduction method: Adult rats were orally gavaged with Shanxi white vinegar at a dose of 10ml/kg body weight for 10 consecutive days. Observe changes in food intake, spontaneous activity, body weight, rectal temperature, stool characteristics, and ...
