Corrosion protection by the organic metal polyaniline: results of immersion, Volta potential and impedance studies.

Properties of the new polyaniline containing primer CORRPASSIV sealed with two different top coats are characterised and compared with top coated samples using no or a conventional zinc-rich primer. Measurements were made using scanning Kelvin-probe (SKP), electrochemical impedance spectroscopy (EIS), voltammetry and analysis of iron and zinc content in electrolytes for testing. Results are presented and the powerful corrosion protection using the organic metal is shown.

Heroin associated nephropathy--a post-mortem study.

Renal specimens were obtained from 179 autopsies of persons autopsied in the Institute of Forensic Medicine, University of Bonn, from 1987 to 1997. All persons were known as intravenous drug addicts. All renal specimens were examined with hematoxylin-eosin, PAS, Siriusred and Gomori (methenamine silver trichrome stain) and investigated with primary antibody against LCA (leucocyte common antigen), CD 68, IgG and IgM. 105 specimens (61.7%) showed a mono-lymphocytic membranoproliferative glomerulonephritis (MPGN), 48 specimens (45.7%) deposits of IgM. No case with focal segmental glomerulosclerosis (FSGS) as reported in male African-American intravenous drug addicts was found. In 37 out of 54 cases, hepatitis antibodies were detected in serum and three out of these 54 cases were HIV-positive. Chronic hepatitis B and C are known to be associated with glomerulonephritis. We found some cases without detection of hepatitis antibodies but with severe glomerulonephritis. In contrast to African-American drug addicts, European drug addicts do not develop a FSGS but a MPGN, partly due to heroin or other adulterants and apparently independent from hepatitis infection.
