[Detection of secretory immunoglobulin A in cervical secretion and in cervicovaginal irrigation fluids]

Abstract

Secretory immunoglobulin A (S-IgA) is an essential part of local immune system of female genital tract. Accordingly the estimation of S-IgA in female genital secretions is important for judgement of immunologic problems in female genital tract. The estimation of S-IgA was carried out by means of an antiserum against human secretory component (anti SC) and S-IgA standard. It was used the single radial immunodiffusion according to Mancini and co-workers. Our results refer to changes in the quantity of S-IgA locally produced in the mucous membranes of female genital tract correlated to the menstrual cycle. The essential results are a decrease of S-IgA in midcycle in cervical mucus and vaginal fluids as well as of fertile and sterile patients.
