Pcb.

(Each entry is one finding in the study if ---


otherwise stated. Some studies have several conclusions.)


All 23 studies described below showed some aspects of the immune system


disorders caused by the influence of PCB. Keep in mind that not all research


equal size and quality.immune system antigens Some study the influence of the old commercial PCB mixtures


(which are of variable composition), or just one or two separate >> << types of printed circuit boards (of 209 possible). This explains some of the differences


results. It is clear that not all PCB have the same effect, and only some are


imunnotoksicheskogo. Some of these studies from the 1970s, when scientists


was simply to learn about the immune effects. Some studies using high and some


using low doses of PCBs. In some cases, the exact dose fee was not known.


Types of printed circuit boards, which stayed in our region and accumulated in the Fox River


and Green Bay fish are likely to be more persistent and toxic payment type. background levels of PCBs / dioxins affect the human fetus and newborn


immune system. (2 studies)


increased number of CD8 + (cytotoxic), TCR alpha beta + gamma and delta TCR


+ T cells


45. 6% fee poisoning patients showed anti-nuclear antibodies, 12. 7% of rheumatoid


(arthritis) and 11 factor. 1% of thyroglobulin antibody


serum immunoglobulin A (IgA), immunoglobulin G (IgG) and immunoglobulin


M (IgM) were raised to 12. 7% 24. 1% and 8. 9% in PCB poisoning



patients thyroglobulin antibodies were found in 19. 5% of people with higher fees



impact of dioxins and related compounds may be associated with immunopathy, such as atopic dermatitis



PCB poisoning of children suffer higher rates bronchitis, respiratory tract


and ear infections and flu Attacks


immune function tests may be necessary to detect changes (eg, delayed hypersensitivity reaction


skin, in vitro propagation of lymphocytes and antibody


synthesis after immunization)


organochlorine compounds, as reported negatively affect the human immune system


, reducing the protection from cancer


, worsening respiratory symptoms associated with exposure to PCB poisoning people


along with viral or bacterial infections


immunoglobulin A and immunoglobulin M levels were reduced, and immunoglobulin G


level was increased


percentage of the total number of T cells, active T cells and decreased cell TMU (2


research)


decreased percentage of total T lymphocytes, active T cells and helper T cells


platelet aggregation, serotonin release and 12-noetherian form


increase readiness for allergic respiratory disease through proof


hyperreactive with mucous membranes


PCB 126 (dioksinopodobnyh PCB) did not kill monocytes but strongly induced


CYP 1A1 in human hepatoma Hep G2 cells


direct effect on lymphocytes, for example , interference epitopes


CD 2-receptors or membrane function tests


was created for selective identification and quantitative determination of PCBs 77, 126 and 169



(each entry is one of the conclusions in study if ---


otherwise stated. Some studies have several conclusions.)


All but one of 45 reviews below show that PCBs are believed to be toxic


for at least Some parts of the immune system. No "safe" level of exposure to PCBs --- any effects PCBs may bear


risk, no matter how small exhibition


dioxins and dioxin-like chemicals (PCBs) present in the environment,


food chain and body tissues at doses or near levels to cause harm >>


<< public health achievement for human consumption close to zero, PCBs will require significant ban


products such as fish


Dioxin is the common name for a series of 75 dibenzodioxins, 135 dibenzofurans


and 209 PCB. damage to the immune system are more dramatic and resistant PCB fruit


and children, in contrast to the PCB exposed adults (2 studies)


immunity and immunosuppression equal decreased resistance to viral,



bacterial, fungal and other infectious agents or increased susceptibility to cancer >> << apoptosis can lead to a change in the ratio of cell loss of tuberculosis and regulations >> << cells in critical numbers leads to disturbances in immune functions


compromised lasix mg iv immune system can disrupt other vital systems for


early development in the womb or childhood


payment of industrial mix is ​​different from the composition of PCB mixtures


which people are exposed to, especially with food


some PCBs bind Ah receptor body, which is associated with the immune system



except sensitization, most effects observed in Boards


animals until there is in humans (1988)


impact of many chemicals or their metabolites in immune function is


through their direct influence or lymphoid tissue. In 1974, scientists had signs of PCB causes the immune system



damage to a number of printed circuit boards (flat and mono-ortho planar PCBs) cause effects


correspondence with those from 2.3 ,7,8-PCDD (dioxins) and PCDFs (furyl)


Research immune produce different results, using a wide range of events



chemical effects can lead to immunosuppression, immunopotentiation, hypersensitivity or perturbed



innate resistance to immunological effects have been demonstrated in people, but data so far


not allow quantitative conclusions. In the absence of quantitative data


research on humans, the risk assessment should be


on the basis of experimental data on animal


responses in the human population is heterogeneous (each of us different genetic susceptibility


because each of us react differently) << >> levels of influence is often low (which can make the effect more subtle, rare >> << or difficult to detect) . << >>
