This section is part 25 of the SN/T 2497 series of standards. This part of the revised use of "toxicology experimental methods and techniques" in the immunotoxicology research methods, the relevant technical content and the above method Exactly the same, in the standard text format by GB/T 1.1 made editorial changes. This part of the State Certification and Accreditation Administration Committee proposed and centralized. This part is responsible for the drafting unit. the People's Republic of China Tianjin Entry-Exit Inspection and Quarantine Bureau, the People's Republic of China Hunan Entry and Exit Inspection Epidemic situation. The main drafters of this part. Lv Gang, Wang Li Bing, Feng Zhizhong, Li Xueyang, Xiong Zhongqiang, Zhao Hao Li Bao. This part is the first release of the entry-exit inspection and quarantine industry standards. Import and export of dangerous chemicals safety test methods Part 25. humoral immune function test

1 Scope

This part of the SN/T 2497 specifies the test principle of the humoral immune function test in the Import and Export Hazardous Chemical Safety Test, Law and test results. This part is applicable to the humoral immune function test for the detection of the immunotoxicity of imported and exported hazardous chemicals.

3 terms and definitions

The following terms and definitions apply to this section. 3.1 Means that the sensitized body is in contact with the same allergen, causing self-tissue damage and/or physiological dysfunction. Hypersensitivity Is an abnormal or pathological immune response. 3.2 According to the mechanism of hypersensitivity reaction, it can be divided into Ⅰ, Ⅱ, Ⅲ, Ⅳ type, which type Ⅰ hypersensitivity is also known as allergic reaction. 3.3 The antigen that causes the hypersensitivity is called the allergen.

4 test principle

In type I hypersensitivity, the allergen for the first time into the body, to stimulate the plasma cells produce IgE, IgE Fc and mast cells or basophilic The FcεR binding of the granulocyte surface allows IgE to adsorb on the surface of these cells, which is the stage of sensitization. When the same allergen is re-entered Sensitized cells, can be adsorbed on the surface of these cells in the IgE binding, causing a series of reactions, so that these cells release histamine and other biological activity Sexual medium, caused by the onset of type Ⅰ allergic reactions, that is, sensitive stage. Histamine is a major bioactive medium, its rapid release, can expand Zhang small blood vessels and increase capillary permeability, stimulate smooth muscle contraction, promote mucosal gland secretion increased; lead to decreased blood pressure, difficulty breathing, Abdominal pain, and even cause anaphylactic shock, leading to death.

5 test method

5.1 Test animals Adult healthy guinea pigs. Test animal feeding conditions should comply with the relevant provisions of GB 14924.1 and GB 14925. ......
