Concentrations of 10 elements were determined using inductively coupled plasma atomic emission spectroscopy, graphite furnace atomic absorption spectroscopy and particle induced x-ray emission spectrometry. Data were treated using multivariate statistical methods. The results showed that the concentrations of several elements in the control urines were significantly raised on Mondays and that controls and stone formers differed with respect to certain elements, also on Mondays. The observed elevations were termed the \"weekend effect\". It is suggested that while stone-formers may regulate their diets throughout the entire week, normals may indulge in dietary excesses over the weekend. The weekend effect highlights the danger of placing too much emphasis on a single measurement of a urinary parameter and alerts investigators to take cognizance of the day on which urine collections are effected, especially when attempting to identify abnormal renal excretion patterns in stone-formers by comparison of their urinary variables with those of controls.","PeriodicalId":77233,"journal":{"name":"Journal of trace elements and electrolytes in health and disease","volume":"8 2","pages":"87-91"},"PeriodicalIF":0.0,"publicationDate":"1994-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"18879919","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}

Hair samples were collected, washed and stored according to IAEA recommendations, and were wet-digested in sealed Pyrex ampoules prior to the determination of Hg-T by gold amalgamation cold-vapour atomic absorption spectrometry. The absolute detection limit was estimated as 0.13 +/- 0.01 ng Hg-T (3 x sigma B1). Accuracy and precision were assessed with the aid of various biological and environmental certified and standard reference materials including human hair, and were satisfactory for ppm and sub-ppm Hg-T. Instrumental neutron activation analysis was used as a reference method for external quality control. The Hg-T content in hair of the study group (2.06 +/- 1.45(8) mg/Kg) was significantly higher than that of the control group (0.43 +/- 0.18(4) mg/kg) (p = 0.0001).

Respective values for mean plasma selenium (+/- SD) in the groups were: 93 +/- 18 micrograms/L, 90 +/- 17 micrograms/L and 96 +/- 18 micrograms/L. A weak significant difference in plasma selenium between women and men was, however, observed in Group I (87 +/- 20 micrograms/L vs. 100 +/- 11 micrograms/L, p < 0.05). Regression analysis showed no significant relationship between plasma selenium and lipid parameters, except in the most hyperlipidemic women of Group III, where a weak correlation between plasma selenium and the HDL-cholesterol/total cholesterol ratio (r = 0.80, p < 0.05) was observed. The present study suggests that the relationship between selenium and HDL-cholesterol has to be further examined, taking into account nutritional, metabolic and genetic factors.","PeriodicalId":77233,"journal":{"name":"Journal of trace elements and electrolytes in health and disease","volume":"8 2","pages":"119-22"},"PeriodicalIF":0.0,"publicationDate":"1994-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"18879914","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 32 of them the clinical and anatomical diagnosis was ischemic heart disease (IHD) and in 8 of them it was acute myocardial infarction (AMI). Concomitant determinations of the concentrations of the above trace elements were determined in 16 normal aortas from subjects who died in accidents or from causes other than atherosclerosis (C). The determinations were done by means of a Perkin-Elmer atomic absorption spectrophotometer, Model 300. The results are expressed in mg/kg of dried tissue. The Cu, Zn, and Cr concentrations were significantly lower (p < 0.01) in the atherosclerotic plaques of abdominal aorta of the deceased patients with IHD and AMI than in the control group. Iron had the tendency to rise but not significantly. The nickel level in the atherosclerotic plaques from abdominal aorta did not change significantly as compared to the controls. We attribute the low values of copper in the atherosclerotic aortic tissue in IHD and AMI to a shift of copper from aortic tissue into the blood. At present, there is no explanation for the low concentration of zinc and chromium in atherosclerotic aortic tissue.","PeriodicalId":77233,"journal":{"name":"Journal of trace elements and electrolytes in health and disease","volume":"8 2","pages":"111-4"},"PeriodicalIF":0.0,"publicationDate":"1994-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"18881903","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}
