OBJECTIVE To evaluate signs of haemolysis in babies of Rh-D negative mothers who underwent prophylaxis with anti-D immunoglobulin during pregnancy. DESIGN The following were evaluated in all babies of Rh-D negative mothers born within a three month period in our department: haemoglobin level, packed cell volume, mean corpuscular volume, reticulocytes, bilirubin level, and direct Coombs' test ...

conclusions based on the findings of the present study, the frequency of toxoplasma infection is high in the studied population, although it is fairly close to the findings of reports from the other areas of iran. results in total, 1910 (29.87%) out of 6393 subjects were found to be infected with toxoplasma gondii. in terms of the seropositivity, 1871 (32.42%) out of 5770 and 128 (2.14%) out of...

The majority of adult B lymphocytes in the mouse bear two immunoglobulin isotypes, IgM and IgD (mu(+)delta(+) cells) (1). A small population of IgM-bearing cells lacks, or expresses very low levels of IgD (mu- predominant [mup] cells) (1). These cells are believed to constitute a less mature subset of B cells analogous to neonatal B cells (2). Based on the time during ontogeny when responses to...

the aim of this study was to evaluate the effects of three lighting programs on immune system and performance of broiler chickens. a total of 288 seven day-old male broiler chicks (ross-308) were randomly distributed between three treatments. each group was housed in the separated room with eight pen and 12-birds per pen. the management conditions were similar for all treatments throughout the ...

The half disappearance time for detectable plasma membrane-associated and cytoplasmic immunoglobulin after treatment of continuously growing diploid lymphocytes with inhibitors of protein and RNA synthesis was studied. Also, the amount of plasma membrane-associated and cytoplasmic immunoglobulin of synchronized cells in the G(1) phase of the cell cycle has been studied. Plasma membrane-associat...

background one of the most important cause of severe neonatal hyperbilirubinemia is hemolysis including rh incompatibility.  the aim of this study was to assess the rate of hyperbilirubinemia due to hemolysis in rh positive neonates  born to rh negative mothers. methods in this retrospective study from march 1998 to february 2003, 60 icteric rh positive newborns that were born to rh negative mo...

A panel of 20 murine CD4+ clones was examined for the presence of surface membrane receptors for IgA, IgM, IgD, IgE, and IgG. High level expression of multiple Fc receptors (FcRs) was found on all Th2 clones. FcR expression was low or undetected on the Th1 clones. The preferential expression of FcR on activated Th2 cells suggests potential mechanisms for immunoregulatory interactions with B cells.
