In order to show the accumulation of Cd, Pb, Cu and Zn in smokers, levels of these metals in serum were determined in 108 subjects: 32 non-smokers, 37 average cigarette smokers and 39 heavy cigarette smokers. The analysis was carried out by potentiometric stripping analysis (PSA) with the Tecator "Striptec System". Backward oxidation time of the amalgamated(More)
Human breast cyst fluid (BCF) proteins were evaluated by sodium dodecylsulfate polyacrylamide gel electrophoresis (SDS-PAGE) after protein denaturation in the presence or absence of 2-mercaptoethanol. Both electrophoretic techniques yielded characteristic and reproducible banding patterns and achieved a high degree of resolution. The known four major(More)
Benign mammary gross cystic disease is the most common breast lesion. Women with apocrine changes of epithelium lining the cysts are at higher risk for developing breast cancer than the normal female population. Sialic acid has drawn considerable interest because of carbohydrate aberrations in malignant cells. The current investigation determined the(More)
The role of urinary cytology in the early diagnosis of cyclosporin nephrotoxicity was studied in 20 bone marrow transplant recipients. There was an evident cyclosporin cytopathy in 35% of bone marrow transplant recipients examined, consisting mainly of degenerative and necrotic abnormalities in cells of the proximal convoluted tubules seen in urinary(More)
5,800 exfoliative cytology smears have been studied during the period 1979-1982. The study was performed as part of the monitoring in a group of patients who underwent kidney transplant at the II Patologia Speciale Chirurgica, University of Rome (Italy). Cytological findings related to non-immunological complications in the first postoperative period are(More)
The results of dosage of human chorionic gonadotropin (HCG) in 75 breast cyst fluids taken from 61 patients suffering from breast gross cystic disease (BGCD), 13 of which had multiple mono and/or bilateral cysts are discussed. The corresponding sera were also examined. Assays were carried out using the ELISA method. For comparison, HCG levels were also(More)
Total hydroxyproline and creatinine concentrations as well as their ratios were determined in 29 amniotic fluid samples from normal pregnancies between the 16th and 20th week of gestation. Total hydroxyproline and creatinine levels, and their ratios, were not statistically different considering either the values at each week or those of the whole 5-week(More)
