Lungcancer

We compared serum and protein-free cultures ofa ras-amplified recombinant BHK-21 cell line(ras-rBHK-IgG), which hyperproduces a lungcancer specific recombinant human monoclonal antibody. Ras-rBHK-IgG cells were shown to grow well, evenin protein-free medium and to be morphologicallysimilar to cells cultured in serum containing medium. However, the growth rate of ras-rBHK-IgG cellswas considerably slower in protein-free medium, whichresults in a longer maintenance period compared with cells cultured in serum containing medium...

Asbestos is a mineral of special technical properties and therefore used in many products all over the world. The inhalation of asbestos causes chronic inflammation of lung--the asbestosis--and pleura--pleuraplaques and pleuritis--and is responsible for mesothelioma and lung cancer. Under normal conditions the diagnosis asbestosis is easy because of the typical x-ray findings and the history of intensive exposure of asbestos. In rare conditions the history of exposure is uncertain and the diagnosis might be difficult...

In the period 1961--1971, 41 patients with a squamous-cell carcinoma were operated upon. The absolute 5-year survival is 47.6% for the lobectomy and 20% for the pneumonectomy. In the period 1971--1976 (6 years), 211 resections for carcinoma (all types) were performed including 19 cases of squamous cell carcinoma, operated in 1971 and also studied in the first part of the work. They represent only 15.2% of all the hospitalized lungcancer patients. The lobectomy/pneumonectomy ratio is 60/40. The postoperative mortality is respectively 4% and 9...
