Sulphidopeptide leukotrienes are potent bronchoconstrictors and increase bronchial hyperreactivity, one of the hallmarks of asthma. We have demonstrated that leukotriene LTE4, the most stable of the sulphidopeptide leukotrienes, elicited an increase in the numbers of eosinophils and neutrophils in the lamina propria of the airway mucosa 4 h after inhalation(More)
Tenascin and fibronectin are extracellular matrix glycoproteins expressed during morphogenesis and tissue repair. In the present study bronchial biopsies were studied by the morphometric method of immunocytochemistry to reveal the distribution of different tenascin and fibronectin isoforms as well as the presence of inflammatory cells in the airway mucosa(More)
Samples of human lung were studied electron microscopically after fixation with glutaraldehyde and osmium tetroxide. Three different types of nerve profiles were found in the human lower respiratory tract. Type I nerve profiles contained small agranular vesicles 30-50 nm and large granular vesicles ranging from 60 nm to 210 nm. Type II nerve profiles(More)
The present study provides light and electron microscopical evidence of Vasoactive Intestinal Peptide - (VIP) like immunoreactive nerves in human lower respiratory tract. Peroxidase antiperoxidase (PAP) technique was used to localize VIP-like immunoreactivity light microscopically and ultrastructurally. Under light microscopy, VIP-like immunoreactive nerves(More)
Lymphocyte infiltrate is a hallmark of inflammatory responses. We have previously shown that de novo-induced endothelial sialyl Lewis x (sLex) expression guides lymphocytes in an L-selectin-dependent manner to sites of acute organ transplant rejections. In this research, we have analyzed five groups of chronic lung inflammations to determine the presence of(More)
BACKGROUND Podocalyxin-like 1 (PODXL) is a cell-adhesion glycoprotein associated with aggressive tumor phenotype and poor prognosis in several forms of cancer. The aim of this study was to investigate PODXL expression in gastric cancer by use of two different antibodies. METHODS By tumor-tissue microarrays and immunohistochemistry we evaluated PODXL(More)
