Introduction

This standard reference USEPAOPPTS880.3550.1996 immunotoxicity test (in English), the technical content of the test guidelines OPPTS880.3550 (1996) immunotoxicity consistent. The test guide is the United States Environmental Protection Agency (USEPA) prevention, pesticides and toxic substances Prevention Office (TheOfficeofPreven- One series of tests Directory tion, PesticidesandToxicSubstances, OPPTS) published with a subject as pesticides and toxic Substance; toxicological data obtained after the submission for review in accordance with EPA regulations. The test OPPTS guide published by merger and weigh multiple test guidelines (including the Office of Pollution Prevention and Toxic Substances (the Chapter I Chapter OfficeofPolutionPreventionandToxics, OPPT) published guidelines, 40 under the title American specification Daquan R sub-chapter in the guide (Title40, ChapterI, SubchapterRoftheCodeofFederalRegulations, CFR), pesticides Planning Office (theOfficeofPesticidePrograms, OPP), the Organization for Economic Cooperation and Development (theOrganizationforEco- nomicCooperationandDevelopment, guide a coordinated OECD) after the final formation. Integration of multiple purpose test guidelines to form a single set of guidelines OPPTS test is to test the number of US Environmental Protection Agency reached According to requirements, so that differences in test methods is reduced to a minimum. Applicability. To meet the US Federal on pesticides, fungicides and rodenticides regulations requirements. Background. The original document was drafted with reference OPP guide 152-18. Product registration for immunotoxicity testing requirements. product registration immune toxicity data requirements based on availability. When asked to carry out sub Chronic (90d) oral toxicity test (OPPTS870.3100), sub-chronic (90d) dermal toxicity test (OPPTS870.3250) or sub-slow Sexual (90d) inhalation toxicity testing (OPPTS870.3465), immunization is required toxicity tests; immunotoxicity test from infected animals Ways should be consistent with toxic exposure pathways sub-chronic toxicity tests. Objective. to understand subchronic exposure to the test substance by immune toxicity test (usually oral exposure) on the body for health damage use. These immune toxicity tests may be qualitative or quantitative evaluation of the test substance to the antibody-mediated and humoral specific and nonspecific cells Immune of. Test substance. technical grade test substance should be measured in each of the active ingredient. Immunotoxicity testing stage. If any of the first phase of the immune toxicity test proved immune toxicity test substance should be open Immune toxicity tests show the second stage (OPPTS880.3800). If the results of the first phase of the immune toxicity test can not be clearly explained Data shows that the test substance or its structural analogues having immunotoxicity, may also be the second phase of the immune toxicity tests. If the first A phase of the trial clearly demonstrated that the test was not immune toxicity, or no relevant data to prove the test substance or its structural analogs immune When toxicity, does not require a phase II trial. Immune toxicity testing of chemicals

3 Terms and Definitions

The following terms and definitions apply to this document. 3.1 Immunotoxicity immunotoxicity Test substance inducing the immune system disorder or inappropriate inhibition or irritation reactions.

4 Test principle

This standard immune toxicity tests, the test substance can be evaluated whether to change or damage the functional state of the immune system. Evaluation indicators include. Immunohistochemistry, cell structure and weight of immune organs; clinical and biochemical blood analysis; blood tests; humoral immune function; cellular immunity. Different groups of animals exposed to different doses of the test substance at least 30d, every day the animals were any clinical toxicity table that appears to observe and record Now. After exposure, the animals were sacrificed on the above evaluation index detection or analysis; some of them need to test the animals with the antigen Sensitization.

5 Test methods

5.1 Experimental Animals 5.1.1 Species and Strains Preferred mice or rats, using the commonly used animal strains. If other species of animal should be justified. All animals should be No parasites and pathogens. Female animals should not yield, not pregnant. 5.1.2 Age Use healthy animals. In the beginning of the experiment, the weight of individual animals should not exceed ± 20% of average weight. At 6 weeks of age - Exposure start 8 weeks of age. 5.1.3 Gender The use of single-sex animals. If the test substance is known to one of the more sensitive animal sex, you should use this gender animals.
