This example provides
us with the opportunity to share some physiological data on
Figure 3:1H NMR signal of
the deoxy Mb proximal histidyl NH signal from rat myocardium.
The peak intensity of the peak at 79 ppm corresponds to the degree
of cellular deoxygenation. The spectra are observed in rat
myocardium in situ: A) control B) dopamine stimulated
C) post dopamine stimulated D) left anterior descending
(LAD) ligated heart. The deoxy Mb signal is detected
only upon LAD ligation, indicating that the cellular pO2 is unperturbed
in the other physiological states.
