چکیده
There is an increasing incidence of sepsis among hospitalized patients. Also, high mortality associated with sepsis and septic shock persists despite appropriate antibiotic therapy. Recent investigations have demonstrated that bacterial antigens stimulate a cascade of cellular mediators or cytokine release. In sepsis and septic shock the response of these cytokines often exceeds natural downregulation and leads to multisystem organ failure and even death in an unacceptably high number of patients. Many investigative studies have shown that tumor necrosis factor (TNF) is the prime mediator of the inflammatory response seen in sepsis and septic shock. Sepsis management in the future will include immune modulating therapy directed against the deleterious effects of cytokines, specifically TNF. This article reviews the current problem of sepsis and the evidence to support the role of TNF in sepsis. Also, recent studies employing monoclonal antibodies against TNF as well as considerations for future studies are discussed. o IWZ ACT-

Absence of a liver-specific membrane protein in a strain of chang cells.
A strain of Chang cells. derived from a human liver line, was examined for the presence of a liver-specific membrane protein (LSP). as described by Meyer zum Buschenfelde. Indirect immunofluorescence and antisera to human. rat, and rabbit LSP were used to demonstrate that LSP was present on isolated human, rat. and rabbit hepatocytes but not on the Chang cells. The results indicate that these C...

متن کاملThe two-way paradigm of transplantation immunology.
The events following organ transplantation require a reciprocal cell interaction which includes both the conventional host-versus-graft reaction and a graft-versus-host component. With all successful transplantation, both graft and recipient become genetic composites. Where donors were available, chimerism has been confirmed in 30-year kidney-recipient survivors, as well as in several liver and...
