7 hydroxyquinoline/hemorrhage

The optimal pH of the proteinase activity of hemorrhagins, BHRa and BHRb, isolated from the venom of Bitis arietans (puff adder) is pH 9. The activity was inhibited by metal chelating agents such as EDTA, 1,10-phenanthroline and 8-hydroxyquinoline, but not by phenylmethanesulfonyl fluoride and

Disability or death due to intracerebral hemorrhage (ICH) is attributed to blood lysis, liberation of iron, and consequent oxidative stress. Iron chelators bind to free iron and prevent neuronal death induced by oxidative stress and disability due to ICH, but the mechanisms for this effect remain

1. Measurements were made of the uptake, metabolism and release of [(3)H]-adrenaline by human platelets in citrated plasma or in an artificial medium.2. Radioactive adrenaline was not taken up at 0-2 degrees C. At 37 degrees C there was a slow uptake which continued for at least 5 hours.3. About
