The Hemolytic Activity of Epoxydammarane Triterpenoids
Planta Medica, 2004The hemolytic activity of the epoxydammarane triterpenoids isolated from the Far-East species of the genus Betula and their semi-synthetic derivatives was investigated. Comparative studies of epoxydammarane triterpenoid activities at pH 5.5 and 5.0 and at 37 and 42 degrees C showed that 3-oxo, 3,11-dioxo, 3- and 11-acetoxy, as well as 3,11-diacetoxy ...

On the hemolytic activity of geophilic dermatophytes
Mycopathologia et Mycologia Applicata, 197010 species each ofK. ajelloi, M. gypseum, M. cookei andT. terrestre were tested for hemolytic activity on media contamining horse, calf or sheep blood. Hemolysis was regularly produced by all species except those ofM. cookei.

Hemolytic Activity of Antimicrobial Peptides
2016For antimicrobial peptides to be interesting for systemic applications, they must show low toxicity against erythrocytes. In this chapter, we describe a protocol for measuring the ability of AMPs to lyse human red blood cells, using melittin as positive control.

Hemolytic activity of rubella virus
Virology, 1978Abstract Hemolytic activity of rubella virus was demonstrated by chelating Ca2+ with EDTA after adsorption of the virus to erythrocytes in the presence of the ion. The hemolysis was inhibited by rabbit serum immunized with the virus. Furthermore, the hemolytic activity co-sedimented in sucrose density gradient centrifugation with the hemagglutinating

Hemolytic Complement Activity in Aqueous Humor
Archives of Ophthalmology, 1983Hemolytic 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

Erythrocyte Cholinesterase Activity in Hemolytic Anemias
Acta Paediatrica, 1965SummaryThe 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 ...

Hemolytic activity in extracts of the diatom Nitzschia
Toxicon, 1997The few reports about diatom toxins are related to central nervous system toxicity, induced by domoic acid. In the present work Nitzschia sp. (Bacillariophyceae) was studied. The cells were cultured in f/2 medium, under 4000 lux and 14/10 hr light/dark cycle.

Platelet Activation in Hemolytic Uremic Syndrome
Seminars in Thrombosis and Hemostasis, 2006Platelet 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.

Leishmania donovani: Hemolytic Activity of Promastigotes
Experimental Parasitology, 1994A 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.

The hemolytic activity of Galleria mellonella hemolymph
Developmental & Comparative Immunology, 1989A hemolytic activity was identified in the hemolymph of normal and immune Galleria mellonella larvae. The hemolysin was active against sheep, human, guinea pig, and rabbit erythrocytes. Hemolysis occurred in the presence of 0.04M EDTA. Vaccination of the larvae with formalized Pseudomonas aeruginosa increased the hemolytic activity.
