Abstract

To estimate the degree of lymphocyte reactivity in patients with internal diseases with immune components, the authors used a new method of investigation, the area of lymphocyte nucleoli (ALN), recently proposed by them. ALN was determined in blood cultures stimulated with phytohemagglutinin (PHA) and sacrificed after three days. The blood was obtained from 120 patients with chronic internal diseases with immune components such as: bronchial asthma, chronic hepatitis, rheumatoid arthritis, systemic lupus erythematosus or chronic lymphocytic leukemia (CLL). The data obtained showed clearly that, compared with the classical test of lymphocyte blastic transformation, ALN--which presented increases even by more than 100% over normal in rheumatoid arthritis and in systemic lupus erythematosus--can supply additional information regarding the degree of reactivity of the cultivated lymphocytes. In CLL, as it was to be expected, ALN values were below the normal.

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.
