ABSTRACT
acute uncontrolled inflammation and tissue injury. n this study we investigated the effect of nimmunochromatographic test- 1:2000) for 1 - 3 days. The effect of PVL on the ASMC morphology or viability was estimated using microscope observations or indirect immunofluores- cence with anti-Smooth muscle -actin antibody and Dapi for DNA staining, and Trypan blue staining, respectively. ASMC incubated with PVL exhibit increased cell size, granular cytoplasm, and ruptured nuclei. Furthermore, PVL reduces cell number mainly in ASMC incubated in the presence of 10% FBS, therefore actively proliferating cells. These results show that apart from the known effect of PVL on immune cells and inflammation process, PVL has a direct toxic effect on airway smooth muscle cells.
