[Study of circulating lymphocytes by monoclonal antibodies in myasthenia gravis].

A significant decline of CD3 cell detected by rosettes and a significant increased of B cell populations were observed. The total CD3+, helper CD4+ and suppressor CD8+ T-cell subsets showed no significant variation em relation to sex, age thymectomy and corticotherapy by monoclonal antibodies.

Glucocorticoid receptors in subpopulations of human lymphocytes defined by monoclonal antibodies.

Glucocorticoid receptors (GR) were investigated in subpopulations of lymphocytes identified by monoclonal antibodies. Purified T (OKT3+) and non-T lymphocyte subpopulations were isolated from human peripheral blood using Degalan bead columns coated with rabbit anti-human IgG. Purified subpopulations of OKT4+ and OKT8+ lymphocytes were obtained by coating the nonadherent population (T cells) from the first column with OKT4+ or OKT8+ and pouring it into a second Degalan column, coated with goat anti-mouse IgG.

[Long term electrophysiological study on patients with acute myocardial infarction and complete heart block. Is cardiac pacing always necessary? (author's transl)].

Unlabelled: Of 335 consecutive patients (pts) admitted to the coronary care unit (CCU) for acute myocardial infarction (AMI), 34 (10%) evidenced complete heart block (HB). The overall inhospital mortality was 14% (47 pts) versus 39% of the HB group (13 pts). No previous conduction disturbances were documented in 58% of pts before appearance of complete HB.

["Pericarditis epistenocardica" as as a marker of extensive myocardial infarction. Clinical, electrocardiographic and enzymatic study (author's transl)].

Pericarditis may complicate the early phase of myocardial infarction (MI). It occurs when necrosis involves the epicardial surface. To verify if pericarditis may be regarded as a marker of extensive MI, 60 patients with anterior or inferior MI admitted to the Coronary Care Unit within 6 hours from onset of symptoms, were studied by clinical, electrocardiographic and enzymatic parameters.
