Pulmonary vasospasm in rabbits infused with stroma free haemoglobin solution.
Effect of infusion of stroma free haemoglobin solution into mice and rabbits was studied. Though no abnormalities were noted in mice, pulmonary vasospasm and hepatocytic necrosis were seen in all rabbits. In addition to reports that low adenosine deaminase levels in the solution could be a cause of vasoconstriction, it is proposed on the basis of present results that either denaturation of haemoglobin molecule itself or release of super oxide anion during oxygenation of haemoglobin, could cause cellular damage leading to toxicity.
