[Endometriosis and deficient intake of antioxidants molecules related to peripheral and peritoneal oxidative stress].

Objective: To evaluate the antioxidant intake and the lipoperoxidation status in plasma and peritoneal fluid of women with endometriosis.

Patients And Methods: The study was carried out in 48 women with endometriosis obtained at the Sterility Clinic from the National Institute of Perinatology. The antioxidant intake was evaluated applying the Questionnaire Assessment of Antioxidants and Retinol Intakes in Mexican women validated by the National Institute of Public Health.

[Vitamin C decreases MMP-9 synthesis induced by hydrogen peroxide in an in vitro chorioamniotic membrane model].

Objective: To evaluate the hydrogen peroxide ability to induce the synthesis of matrix metalloproteinase-9 (MMP-9) in an in vitro chorioamniotic membrane model.

Material And Methods: An experimental, transversal, analytic and prospective study was made. From amniotic membranes (n = 13) of term labour pregnant women chorionic and chorioamniotic explants were prepared; these were stimulated with hydrogen peroxide [200 mcM].

[Endometriosis and discouragement of immunology cytotoxic characteristics].

Objective: To determine the immunology kind of response Th1 (cytotoxic) or Th2 (humoral) prevailing at peripheral and peritoneal environment at endometriosis women (ENW).

Study Design: Observational, transverse, analytical, retrospective, cases and controls.

Material And Methods: Cooperative and cytotoxic lymphocytes obtained from peritoneal fluid (PF) and peripheral blood (PB) were used to determine IFN-gamma and IL-2 intracellular synthesis at ENW.

[Changes in the systemic immunologic response in association with endometriosis using an animal model].

Introduction: Endometriosis constitutes the growth of endometrial tissue in a place other than the uterine cavity. Its etiopathogenesis is unknown, although there is some evidence associating it with the decrease of cytotoxic activity in the immunological system.

Objective: Evaluating the relationship between the development of ectopic endometrial tissue and the immunological status, and enumerating lymphocyte subpopulations and cytokine synthesis in T lymphocytes, using a murine endometriosis model.
