The patients were treated with a split-course technique with 60-Cobalt. A total of 30 patients with unresectable carcinoma have been studied. Measurements of vital capacity (V.C.) and forced expiratory volume at one second (F.E.V.1) were made prior to therapy; at the beginning and end of the split; upon completion of therapy; and thereafter at 1, 2, and 6 months post therapy. The percentage changes in V.C. and F.E.V.1 from pretreatment values are plotted against time. A trend to improve throughout the treatment course is suggested by these results. Twelve patients have been studied at six-month follow-up: eight of the patients showed less than a 10% reduction from pretreatment V.C. and F.E.V.1 and had no respiratory impairment; of the other four patients, three had evidence of progression of disease in the thorax.</p>","PeriodicalId":76463,"journal":{"name":"Revista interamericana de radiologia","volume":"3 1","pages":"15-9"},"PeriodicalIF":0.0,"publicationDate":"1978-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"11845847","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}

In animals plasma flow and glomerular filtration rate were determined by the PAH extraction and by the innulin clearance technique. In patients renal blood flow measurements were carried out using the Xenon133 washout technique. Baseline studies were obtained and repeated following the intravenous infusion of 20% mannitol. A significant increase in total renal blood flow could be demonstrated in experimental animals, but only a minimal increase of total flow was demonstrated in man following the infusion of mannitol. This observation suggests that the diuretic effect of mannitol is very likely due to the osmotic effect in the tubule causing increased interstitial renal pressure rather than by an increase of actual renal blood flow. This observation is supported by the clinical experience that mannitol remains a powerful diuretic in even hypotensive patients with low renal blood flow.</p>","PeriodicalId":76463,"journal":{"name":"Revista interamericana de radiologia","volume":"3 1","pages":"21-6"},"PeriodicalIF":0.0,"publicationDate":"1978-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"11845848","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}

Whether pneumothorax and sarcoidosis are two independent processes occurring in the same individual or whether the pneumothorax is causally related to the sarcoidosis has not been determined.
