1Disparities of conjugating protective enzyme activities in the colon of patients with adenomas and carcinomas显示文摘AIM:To investigate the metabolic enzymatic capacity of the colon mucosa to detoxify noxious carcinogenic compounds.METHODS:We investigated the activity of 2 conjugating enzymes-the microsomal uridine glucuronosyltransferase(UGT)and the cytosomal glutathione S-transferase(GST)in the uninvolved mucosa of the colon transversum and sigmoideum in patients with adenomatous polyps and colorectal cancer.Biopsies were taken from the mucosa during colonoscopies which were done for clinical(diagnostic)reasons.After storage,the biopsy material was homogenized and after differential centrifugation the enzyme assays were performed with 4-nitrophenol(UGT)and 1-chloro 2,4-dinitrobenzene(GST)as substrates.RESULTS:About 48 patients were included of which28 had adenomas and 20 had colorectal carcinomas confirmed by histopathology.Enzyme activities were expressed as nmol/mg per minute protein for the GST and as pmol/mg per minute protein for the UGT.Analysis of variance(F-test)indicated that both enzymes were more widely distributed in adenoma than in cancer patients.The means±SD were smaller for cancer patients:GST for adenomas 268±152 vs 241±69 for carcinomas and UGT for adenomas 197±200 vs 150±86 for carcinomas.CONCLUSION:Compared to patients with adenomatous colon polyps those with colorectal carcinoma exhibited a lower capacity of detoxifying enzyme metabolism and their activities clustered over a smaller range.Harald P Hoensch Hennie MJ Roelofs Lutz Edler Wilhelm Kirch Wilbert HM Peters 2013World Journal of Gastroenterology2013,19,36:3
2The Role of Organic Matter During Metal Enrichment in Permian Kupferschiefer of the Rudna Mine,Southwest Poland显示文摘The bulk composition of organic matter and saturated and aromatic hydrocarbons extracted from 16 samples collected from two Kupferschiefer profiles in the Rudna mine, Southwest Poland has been analyzed to study the role of organic matter during base metal enrichment in the Kupferschiefer shale. The results indicated that the extract yields and saturated hydrocarbon yields decreased with increasing base metal contents. GC and GC/MS analyses indicated that n-alkanes and alkylated aromatic compounds were depleted and may have served as hydrogen donators for thermochemical sulfate reduction. The enrichment of base metals is closely connected with the destruction of hydrocarbons.孙玉壮 WILHELM PüTTMANN 2003Chinese Journal Of Geochemistry2003,22,1:2
