Solubility and hemolytic activity of uranium trioxide

Environmental Research, 1979
UO/sub 3/ is often classed as an insoluble material by reason of its low solubility in water, but its solubility is greatly enhanced in solutions of some inorganic salts. Dissolution in NaCl, KCl, or KNO/sub 3/ solutions occurs by conversion of UO/sub 3/ to uranyl hydroxide hydrate (UHH) followed by cation exchange with structural hydroxyl groups. Acid

Hemolytic Complement Activity in Aqueous Humor

Archives of Ophthalmology, 1983
Hemolytic C1, C4, C3, and C5 and IgG levels were measured in aqueous humor obtained at surgery from human eyes without inflammation or previous surgery (group 1), eyes with previous surgery (group 2), and eyes with anterior uveitis (group 3). Serum hemolytic complement and IgG levels were also compared with aqueous humor levels. Aqueous humor from eyes

Leishmania donovani: Hemolytic Activity of Promastigotes

Experimental Parasitology, 1994
A hemolytically active component was found to be present in Leishmania donovani promastigotes for the first time. It lysed human and rabbit erythrocytes to varying degrees. The optimal pH for the activity was found to be 5.8. The rate of hemolysis was dependent on both erythrocyte and parasite concentrations.

Erythrocyte Cholinesterase Activity in Hemolytic Anemias

Acta Paediatrica, 1965
SummaryThe erythrocyte cholinesterase activity was studied in 41 thalassemic children, 15 cases of microdrepanocytosis (sickle cellthalassemia disease), 13 cases with favism, children with autoimmune hemolytic anemia, 2 cases of congenital spherocytosis, 2 children with aplastic anemia and 4 with iron deficiency anemia, as well as in children with ...

Platelet Activation in Hemolytic Uremic Syndrome

Seminars in Thrombosis and Hemostasis, 2006
Platelet consumption in platelet-fibrin aggregates leading to thrombocytopenia and small vessel obstruction are major features of the hemolytic uremic syndrome (HUS). Although thrombocytopenia has been correlated to poor prognosis, the mechanisms by which thrombocytopenia develops in HUS have not been completely elucidated.

Surface charge and hemolytic activity of asbestos

Environmental Research, 1977
Abstract Surface charge, represented by zeta potential, and hemolytic activity were measured for the five asbestos reference samples of the International Union against Cancer (UICC). Zeta potentials in distilled water at pH 7.4 for chrysotiles A and B were +40.5 and +52.5 mV, and for amphiboles crocidolite, amosite, and anthophyllite were −50.4, −58 ...

Hemolytic activity of the Pasteurella haemolytica leukotoxin

Infection and Immunity, 1995
A Pasteurella haemolytica mutant incapable of producing leukotoxin was created by allelic replacement. Concentrated culture supernatants from wild-type P. haemolytica, but not from the mutant, contained the 102-kDa leukotoxin protein and lysed bovine lymphoma cells and sheep erythrocytes. Wild-type P. haemolytica demonstrated the typical beta-hemolytic

Hemolytic action of surface-active electrolytes

Journal of Colloid and Interface Science, 1966
Abstract The hemolytic action of several homologous series of anionic and cationic surface-active electrolytes (C4 to C12) was studied. A marked difference in hemolytic activity was found between the anionic and cationic agents with shorter alkyl chain length.

Expression of hemolytic activity by Plesiomonas shigelloides

Journal of Clinical Microbiology, 1993
More than 90% of the Plesiomonas shigelloides strains that we tested produced a beta-hemolysin, as judged by the results of agar overlay and contact-dependent hemolysis assays. The hemolysin was cell associated, was active against the erythrocytes of various animal species, and was synthesized at both 25 and 35 degrees C.

The Hemolytic Activity of Homocysteine Is Increased by the Activated Polymorphonuclear Leukocytes

Biochemical and Biophysical Research Communications, 1996
Homocysteine is an accepted risk factor when its plasma level exceeds the physiological upper limit of 12 mumol/L. We found in vitro that homocysteine is able to lyse the erythrocytes (RBCs) at higher concentrations than 15 mumol/L only when activated polymorphonuclear leukocytes (PMNL) are present.
