Background & Objective: Dangerous O is very important to transfusion medicine and there has been reports by Food and Drug Administration (FDA) regarding some death relating incidences. As high iso-antibody production is closely associated with different immune reactions, a survey on the different immune response of dangerous O donors can lead to understanding their immune respo...

The level of antibody produced in response to calf skin collagen in mice is influenced by genes which are closely linked to the I region of the H-2 major histocompatibility complex. This influence is shown to be expressed during lymphoid maturation by testing the antibody responsiveness to collagen in two types of chimeric mice. First, high responder and low responder parental strain mice were ...

To determine whether a preoperative blood transfusion could influence corneal graft rejection, full-thickness 3 mm orthotopic corneal grafts were performed in Dark Agouti (DA) rats from syngeneic (DA) or allogeneic (Brown Norway and Lewis) inbred donors and in Lewis rats from syngeneic (Lewis) or allogeneic (DA) donors. Rats with syngeneic grafts showed no signs of rejection. The corneal button...

Responder and nonresponder mice primed with poly-(L-glutamic acid,L-lysine,L-phenylalanine) (GLPhe), the response to which is under the control of immune response (Ir) genes, were used as a source of both types of helper T cells required for a T15 idiotype dominated T-dependent anti-phosphorylcholine (PC) response. It was found that the activity of one of the helper T cells needed for an anti-P...

Genetic regulation of immunological responsiveness was studied at the cellular level by comparing the limiting dilutions of immunocompetent cells from spleen, thymus, and bone marrow of high and low responders as a function of the poly-L-prolyl and poly-DL-alanyl side chains of two synthetic polypeptide immunogens. The spleens of immunized and unimmunized high responder DBA/1 mice were found to...

Background: The affordable protocol to prevent the severe OHSS in two groups of patients PCO syndrome and non PCO high responder. Methods and Materials: PubMed and Medline were searched from January 2000 till end of May 2014. This Study investigates whether the mild protocol is associated to prevent severe OHSS in infertile female. Results: According to this survey, 9 studies were included and ...

We have studied the properties of helper T cells specific for sheep erythrocytes (SRBC), keyhole limpet hemocyanin (KLH), or poly-L-(Tyr,Glu)-poly-DL-Ala-poly-L-Lys [(T,G)-A--L]. These T cells differentiated and were primed in vivo in irradiation chimeras constructed of various combinations of F1 and parental bone marrow donors and irradiated recipients. Primed T cells were then tested for help...
