Non-vascularized hearts of buffalo sculpin (Enophrys bison)
were used to investigate the cardiac toxicity of compounds that
cause methemoglobinemia. The affinity of sculpin cardiac myoglobin
for oxygen (P50 = 1.10 torr at 20 C°, pH 7.8) was lower than that of
mammals studied (P50 = .44 and .76 torr for...
