The production of human anti-red blood cell (RBC) Igs in vitro from immunized individuals would greatly facilitate the genetic analysis of the human immune response to RBC antigens and also provide useful serologic reagents. Technical difficulties inherent in human B-cell immortalization have led to the development of molecular approaches that bypass the need for cell transformation. By cloning...

Rhesus (Rh) haemolytic disease has been greatly reduced in incidence by the prophylactic programme with anti-D immunoglobulin, but it will not be eliminated. Even with careful documentation and close liaison between medical, nursing and laboratory personnel, there are occasional failures to administer anti-D to Rh-negative women at risk of sensitization following either delivery (Crowle, 1974) ...

Effects of ractopamine hydrochloride (RH) and zilpaterol hydrochloride (ZH) on saleable yield of carcass sides from calf-fed Holstein steers were evaluated using steers implanted with a progesterone (100 mg) plus estradiol benzoate (10 mg) implant followed by a terminal trenbolone acetate (200 mg) plus estradiol (40 mg) implant. Steers were blocked by weight into pens (n = 32) randomly assigned...

The combination of hormonal treatment based on a long-acting delivery system for the agonist [6-D-tryptophan]luteinizing hormone-releasing hormone ([D-Trp6]-LH-RH) with the chemotherapeutic agent Novantrone (mitoxantrone dihydrochloride) was studied in the Dunning R3327H rat prostate cancer model. Microcapsules of [D-Trp6]-LH-RH formulated from poly(DL-lactide-co-glycolide) and calculated to re...

T HE D ANTIGEN has been detected on the surface of Rh( D) leukocytest by a variety of indirect technics. Dausett, Colombani and Evelin1 used the methods of antiglobulin consumption and anti-D absorption by leukocytes. Jankovi#{233} and Lincoln showed fluorescence of Rh(D) leukocytes with fluorescein conjugated antihuman globulin after the exposure of leukocytes to anti-D serum. Hollman was able...

A patient with warm autoimmune hemolytic anemia (AIHA) due to predominance of immunoglobulin A (IgA) with an Rh specificity, considered to be the first case in Korea, is described. A 13-year-old male patient with severe hemolytic anemia showed a weak reactivity (1+) in the direct antiglobulin test (DAT) by using anti-IgG antiglobulin reagent. This finding, however, could not fully explain the p...

We are reporting a rare case of hemolytic disease of newborn with weak D antigen in child. A 3rd order male child of G3P3A0 mother was admitted at 8th h of life with jaundice. Blood group of both mother and child were A Rh D negative. Baby's direct coombs test was positive. Weak D antigen was positive in baby. Hematological parameters showed all the signs of ongoing hemolysis, and the bilirubin...

Rh(ttp)(C(7)H(7)) rearranged to give Rh(ttp)(CH(2)Ph) quantitatively at 120 °C in 12 d (ttp = 5,10,15,20-tetratolylporphyrinato dianion). This process is 10(10) faster than for the organic analogue. Mechanistic investigation suggests that a Rh(II)(ttp)-catalyzed pathway is operating.
