Standardization of experimental animals consists of three parts: standardization of production conditions, standardization of animal quality and standardization of animal experimental conditions. Among them, the standardization of experimental animal production conditions and animal experimental conditions is the standardization of experimental animal environment. If the production environment of experimental animals is not standardized, it is impossible to cultivate a certain quality of experimental animals. Similarly, even if high-quality experimental animals are used, the experimental results will change greatly in the non-standard experimental animal environment. For example; The increase of ammonia concentration in the environment can increase the incidence of mycoplasma pneumonia in rats. The cleanliness of the environment also has a certain influence on the establishment of human tumor xenotransplantation model. The survival rate of xenografts in nude mice raised in isolation environment is often higher than that in laminar flow frame. The environment of experimental animals is the decisive factor for the quality standardization of experimental animals. Because the experimental animal environment controls microorganisms. Improve the quality of microbiology; The genetic quality of experimental animals is guaranteed by genetic influencing factors.
(2) Environmental control can ensure the correct results of experimental research.
(3) The standard environment can provide suitable conditions for experimental animals and animal workers and protect people's health from harmful factors.
Our aim is to cultivate and utilize inferior experimental animals and carry out life science and related scientific research. At the same time, we should also pay attention to the fact that in this process, there are many factors that pollute the human environment and endanger life safety, such as epidemic bleeding, anthrax, plague, rabies and other infectious diseases, as well as dangerous research conducted by experimental animals such as infection experiments, radiation experiments and chemical experiments, which directly threaten the life safety of workers and even the surrounding people. Therefore, our research should be people-oriented and take the organic system of "experimental animal-environment-human" as the research object, so as to ensure that experimental animal science can benefit mankind under safe and effective conditions.
