Reticuloendothelial

Blood-forming tissues consist of bone marrow, spleen, lymph nodes and the reticuloendothelial system. These produce the elements of blood and are important for the immunological defense systems. [Pg.304]

Miller Scott (1985) reported marked reduction in thymus weight in rats fed dioctyltin dichloride for 8 or 12 weeks at a level of 75 mg/kg diet. Numbers of lymphocytes together with T cell subpopulations were reduced in treated rats, but no difference was seen in antibody response to sheep red blood cells in vivo. No evidence was foimd of in vitro cytocidal effects of dioctyltin dichloride on blood lymphocytes. Evans et al. (1986) dosed pregnant and non-pregnant rats for 3 weeks at 75 mg/kg diet and reported severe thymic atrophy and extensive vacuolation of reticuloendothelial cells in pregnant animals only. [Pg.26]

The chemical conversion of heme to bihmbin by reticuloendothelial cells can be observed in vivo as the purple color of the heme in a hematoma is slowly converted to the yellow pigment of bilirubin. [Pg.278]

Reticuloendothelial system Cells located throughout the body that can phagocytose particulate matter. [Pg.1575]

Polyanionic polymers can enter into biological functions by distribution throughout the host and they behave similar to proteins, glycoproteins and polynucleotides which modulate a number of biological responses related to the host defense mechanism. These are enhanced immune responses, and activation of the reticuloendothelial system (RES) macrophages. [Pg.10]

Tissue distribution of lipo-preparations. The tissue distribution of lipid microspheres in normal and pathologic animals was studied. Research into liposomes of similar size suggested that lipid microspheres accumulated preferentially in the reticuloendothelial system, inflammatory sites, or certain tumors. The distribution of lipid microspheres to these tissues has been found in our studies (7,2). Interestingly, our study showed that lipid microspheres accumulated, particularly at high concentrations, in damaged vascular walls such as atherosclerotic vascular walls. [Pg.265]

Negatively charged particles are more rapidly cleared from the blood than are neutral and positive ones [75], The clearance rate of particles by the reticuloendothelial system is inversely related to the load of the particles that is, the rate of clearance of a larger dose of microparticulate is slower than for a smaller dose [76],... [Pg.548]

In normal human subjects, some 25 % of total body iron (800-1000 mg) is present in the storage forms, mostly as ferritin. Whereas it is likely that all mammalian cell types contain some ferritin, haemosiderin in normal subjects is essentially restricted to cells of the reticuloendothelial system. Ferritin turns out to be almost universal in its distribution ferritin and ferritin-like proteins have been found in all organisms except for one or two archaebacteria. In contrast, haemosiderin has not been found to any extent outside of iron-loaded animals, except for a brief report of a phytosiderin in pea seeds (Laulhere et ah, 1989). [Pg.173]
