Changes of lymphocyte subpopulations during and after pulmonary lobectomy.

ALTERATION OF T-LYMPHOCYTE SUBPOPULATIONS IN SUBACUTE AND CHRONIC BRUCELLOSIS

Human brucellosis is a major health problem in developing countries. A number of patients with human brucellosis do not recover from the acute stage of the disease and pass into the chronic form. Since the pathophysiology of this change is not well understood, we studied the T-cell subsets during the acute, subacute and chronic forms of human brucellosis. In this study we found alterations...

Lymphocyte Subpopulations in Pulmonary Tuberculosis Patients

Protection against Mycobacterium tuberculosis is based on cell-mediated immunity, most importantly involving CD4(+) and CD8(+) T-cell subsets. The aim of this study was to evaluate CD4(+) and CD8(+) T-cell profiles and CD19(+) and CD3(+)CD(16 + 56)(+) populations in patients with pulmonary tuberculosis. CD4(+) and CD8(+) T cells, B-lymphocytes, and natural killer (NK) cells were evaluated in 75...

Changes in Pulmonary Volume following Lobectomy

The ablation of any considerable portion of a vitally functioning organ immediately raises the question of a reduction in functional capacity. With respect to the removal of one or more lobes of the lung, one may ask; first, what are the immediate and remote effects on the total lung volume and its component parts; second, what changes occur in the hemorespiratory exchange, and how long do they...

Aging related changes of circadian rhythmicity of cytotoxic lymphocyte subpopulations

BACKGROUND Immunosenescence is a process that affects all cell compartments of the immune system and the contribution of the immune system to healthy aging and longevity is still an open question. Lymphocyte subpopulations present different patterns of circadian variation and in the elderly alteration of circadian rhythmicity has been evidenced. The aim of our study was to analyze the dynamics ...
