[Autoimmune aspermatogenetic orchiepididymitis in guinea pigs induced by water-soluble adjuvants]. 1977

F Toullet, and F Audibert, and G A Voisin, and L Chedid

Use was made of water-soluble adjuvant fractions with homologous sperm, sperm extract or sperm autoantigens to induce autoimmune aspermatogenic orchiepididymitis (AIAO) in guinea-pigs. Guinea-pigs were injected with soluble sperm extract or sperm purified autoantigen S emulsified in incomplete Freund adjvant (IFA) together with two synthetic watersoluble adjuvants, Mur-Nac-L-Ala-D-isoGlu et Mur-Nac-L-Ala-acide D-isoGlu. These animals developed lesions of AIAO, delayed hypersensitivity reactions and specific anti-spermatozoa antibodies. These lesions and reactions were comparable to the ones induced in a control group treated with the same spermatozoa extract or autoantigen S in complet Freund adjuvants. No lesion was observed in the absence of IFA, Other guinea-pigs received a mixture of spermatoza or purified sperm autoantigens, S, P, T. and of polyadenylicpolyuridylic complex either in saline or emulsified in IFA. The recipients of sperm or autoantigen T mixed with Poly A:U, with ou without IFA, displayed lsdions of AIAO; autoantigen S and Poly A:U in IFA, provoked AIAO but did not do it in the absenceof IFA.

D004823	Epididymitis	Inflammation of the EPIDIDYMIS. Its clinical features include enlarged epididymis, a swollen SCROTUM; PAIN; PYURIA; and FEVER. It is usually related to infections in the URINARY TRACT, which likely spread to the EPIDIDYMIS through either the VAS DEFERENS or the lymphatics of the SPERMATIC CORD.	Epididymitides
D006168	Guinea Pigs	A common name used for the genus Cavia. The most common species is Cavia porcellus which is the domesticated guinea pig used for pets and biomedical research.	Cavia,Cavia porcellus,Guinea Pig,Pig, Guinea,Pigs, Guinea
D000276	Adjuvants, Immunologic	Substances that augment, stimulate, activate, potentiate, or modulate the immune response at either the cellular or humoral level. The classical agents (Freund's adjuvant, BCG, Corynebacterium parvum, et al.) contain bacterial antigens. Some are endogenous (e.g., histamine, interferon, transfer factor, tuftsin, interleukin-1). Their mode of action is either non-specific, resulting in increased immune responsiveness to a wide variety of antigens, or antigen-specific, i.e., affecting a restricted type of immune response to a narrow group of antigens. The therapeutic efficacy of many biological response modifiers is related to their antigen-specific immunoadjuvanticity.

D000818	Animals	Unicellular or multicellular, heterotrophic organisms, that have sensation and the power of voluntary movement. Under the older five kingdom paradigm, Animalia was one of the kingdoms. Under the modern three domain model, Animalia represents one of the many groups in the domain EUKARYOTA.
