Interferon gamma production by PAS-positive T lymphocytes of chagasic patients infiltrated into human hearts in the sites of lesions.

Unlabelled: In the blood of chagasic patients, a high number of T-lymphocytes producers of a PA.S.-positive substance was found, more numerous in chagasics with abnormal electrocardiogram.

[Chagas cardiopathy: identification and quantification of infiltrating cells in the hearts of cardiac death patients of different ages].

Unlabelled: The purpose of this work was to obtain new data on factors intervening in the production and progression of human chagasic cardiopathy (HChC) with death by cardiac failure. We studied cardiac samples of patients that died at an early mean age versus others that died at older ages. The infiltrating cells were characterized and quantified by means of specific monoclonal antibodies and inmunohistochemical methodology; and by classical histological and histochemical methods.

Lipids are important cell components, both from the structural and the functional point of view. Besides, they intervene in transporting functions, cell recognition and immunity. Essential Fatty Acids (EFA) are important for the functional and structural maintenance of animal organisms.

[The esophagus in patients with Chagas disease in Córdoba, Argentina. Histologico-immunohistochemical, and evacuation time].

Unlabelled: With the purpose of to establish the status of the oesophagus with respect to chagasic aendemia in subjects of the central rural zone of Argentine, we search the esophagic evacuation duration-time by means of a radiologic standardized test which studied the ingested barium transit as well us the caliber of a given oesophagus. 87 chagasic subjects from rural zones of Cordoba and Santiago del Estero, Argentina, were studied. All had several positive serological test for Chagas' infection.
