Venous occlusion and chronic cigarette smoking: dose-dependent decrease in the measurable release of tissue-type plasminogen activator and von Willebrand factor.

This study was aimed at examining the effect of chronic cigarette smoking on a venous occlusion test. Two groups of young healthy men, a control group of 20 non-smoking subjects and a group of 21 smoking subjects having an average consumption of 17.6 packages.

[Use of flow cytometry in the study of a non-specific immunodeficiency in children. A case].

Using flow cytometry, we explored a case of nonspecific immunodeficiency in a seven month old girl with repeated infections. This method showed evidence of granulocyte phagocytosis and oxidative metabolism abnormalities suggesting the diagnosis of a variant form of chronic granulomatous disease (CGD). Findings also showed that flow cytometry can be useful to study phagocytic cells during the neonatal period as it allows rapid multiparametric analysis with a very small amount of blood.
