Immunological effects of chlorinated dibenzo-p-dioxins.
2,3,7,8-Tetrachlorodibenzo-p-dioxin (TCDD) and structurally similar halogenated aromatic hydrocarbons cause a broad range of immunologic effects in experimental animals including decreased host resistance to infectious disease and suppressed humoral and cell-mediated immune responses. In the mouse, TCDD immunotoxicity has been shown to be an aryl hydrocarbon (Ah) receptor-dependent process. How...
متن کاملToxicology of chlorinated dibenzo-p-dioxins.
Severe toxicological responses have been associated with certain chlorodibenzodioxins. One of these responses is chloracne, a folliculosis first associated with skin contamination by chlorohydrocarbons in 1899 (1)). Serious outbreaks of chloracne-like lesions associated with runaway reactions in the production of 2,4,5-trichlorophenol occurred in Germany in the early 1950's (2). 2,4,5Trichlorop...
متن کاملDegradation of Chlorinated Dibenzofurans and Dibenzo-p-Dioxins by Sphingomonas sp. Strain RW1.
The ability of the dibenzofuran- and dibenzo-p-dioxin-mineralizing bacterium Sphingomonas sp. strain RW1 (R.-M. Wittich, H. Wilkes, V. Sinnwell, W. Francke, and P. Fortnagel, Appl. Environ. Microbiol. 58:1005-1010, 1992) to oxidize chlorinated derivatives of dibenzofuran and dibenzo-p-dioxin was analyzed. Strain RW1 degraded several mono- and dichlorinated dibenzofurans and dibenzo-p-dioxins, b...
متن کاملBIOANALYTICAL DEVELOPMENT OF A HOMOGENEOUS PHOSPHORESCENT IMMUNOASSAY FOR THE DETECTION OF POLY- CHLORINATED DIBENZO-p- DIOXINS
Ahomogeneous immunoassay for dioxins was developed using a phosphorescent label for detection. A dioxin derivative was conjugated to Pt-coproporphyrin. In the assay, when the antibodies against dioxin (DD3) were bound to the phosphorescent conjugate, the signal from Pt-coproporphyrin was
متن کاملChlorinated and brominated dibenzo-p-dioxins and dibenzofurans in surface sediment from Taihu Lake, China.
Polychlorinated dibenzo-p-dioxins and dibenzofurans (PCDD/Fs) and polybrominated dibenzo-p-dioxins and dibenzofurans (PBDD/Fs) in surface sediment samples from Taihu Lake--an important water supply of the Yangtze River Delta, China--were investigated in the present study. Concentrations of PCDD/Fs ranged from 0.91 to 4.8 pg TEQ g(-1) dw (mean: 2.9 pg TEQ g(-1) dw, TEQ: Toxic Equivalent), which ...
