[Effect of phenylmercury derivatives on human oxyhemoglobin]
Abstract:
By the dynamics of human oxyhemoglobin coagulation in the presence of phenyl mercury acetate in tris-AcOH buffer, pH 7.2 the number of moles of PhHg+ stechiometrically bound with protein at different temperatures was estimated. Within the temperature range 15-30 degrees C this value is constant--32-34 mole per 1 mole of HBO2-tetramer. Within the range 30-40 degrees C it rises to approximately 40. Coagulation of oxyhemoglobin modified with PhHg+ cation is reversible in contrast to HBO2 coagulation modified with uncharged PhHgCl.

Types of Hypoxia
There are four primary types of hypoxia, each resulting from a different cause:
1. Anemic hypoxia: This type occurs due to insufficient oxygen delivery caused by a lack of red blood cells (RBCs) or RBCs with abnormal or...
