Abstract

Due to the increasing interest in studies of apoptosis (programmed cell death) in the pathogenesis of many diseases and to the emergence of data on the direct impact of apoptotic disorders on the course of bronchial asthma and the magnitude of the obstructive syndrome, this study was undertaken to investigate apoptosis in patients with new-onset pulmonary tuberculosis who had varying bronchial obstructive syndrome. Twenty-eight patients with new-onset tuberculosis, including 25 (89.3%), 2(7.1%), 1(3.6%) patients with infiltrative, disseminated, and fibrocavernous pulmonary tuberculosis, respectively, were examined. The study of external respiratory function included spirometry, determination of the flow-volume of forced expiration, body plethysmography, examination of lung elasticity by esophageal probing. The mechanisms of spontaneous apoptosis of peripheral lymphocytes from donors and patients with pulmonary tuberculosis were studied. The apoptosis was evaluated in dynamics by some parameters: the change of the mitochondrial potential (MP), the level of phosphatidyl serine, as well as DNA fragmentation by flow cytofluorometry. The results have indicated that there are significant signs of impaired peripheral lymphocytic apopt...Continue Reading

Asthma

This feed focuses in Asthma in which your airways narrow and swell. This can make breathing difficult and trigger coughing, wheezing and shortness of breath.

Allergy and Asthma

Allergy and asthma are inflammatory disorders that are triggered by the activation of an allergen-specific regulatory t cell. These t cells become activated when allergens are recognized by allergen-presenting cells. Here is the latest research on allergy and asthma.

Apoptosis

Apoptosis is a specific process that leads to programmed cell death through the activation of an evolutionary conserved intracellular pathway leading to pathognomic cellular changes distinct from cellular necrosis
