Since type II cells secrete lung surfactant, treatment may alter surfactant composition. In 8 patients with nonresectable lung cancer, we performed bronchoalveolar lavage before and after MACC polychemotherapy (methotrexate, doxorubicin HCl, cyclophosphamide and lomustine). Before treatment, cellular composition and the phospholipid and fatty acid constituents of lavage surfactant were similar to those found in control subjects. After MACC polychemotherapy there was, in all patients, a mild decrease in the number of immune effector cells, without changes in the relative proportion of cell types. In addition, MACC therapy resulted in a significant decrease of phosphatidylcholine levels, and increased levels of phosphatidylglycerol, whereas the levels of palmitic lavage surfactant were decreased. These MACC treatment abnormalities of the phospholipid and fatty acid composition of lung surfactant may reflect preclinical pulmonary toxicity. The decrease in the numbers of bronchoalveolar cells suggests that the changes in surfactant composition may be chemically induced rather than immune mediated.</p>","PeriodicalId":12053,"journal":{"name":"European journal of respiratory diseases","volume":"71 5","pages":"400-9"},"PeriodicalIF":0.0,"publicationDate":"1987-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"13969535","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

After short-term (30 min) incubation, there was an increase in the nitroblue tetrazolium (NBT) reduction of the monocytes both at rest and during stimulation with E. coli bacteria, and enhanced ingestion of fluorescein-labelled yeast particles. Electron microscopic examination of the same monocytes showed an active cell surface with numerous protrusions. Long-term (24 h) incubation with surfactant resulted in a reduced ability of the cells to adhere to plastic dishes. Although the NBT-reduction of resting monocytes was increased after long-term incubation with surfactant, the additional enhancement of NBT-reduction after stimulation with bacteria was decreased. These cells were rounded, usually devoid of surface structures, their nuclei were condensed, and their cytoplasm filled with surfactant material. Thus, monocytes are initially activated in the presence of surfactant, but if the cells become overfed with surfactant lipids their functional capacity decreases.</p>","PeriodicalId":12053,"journal":{"name":"European journal of respiratory diseases","volume":"71 5","pages":"410-8"},"PeriodicalIF":0.0,"publicationDate":"1987-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"14454934","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
