The level of MnSOD measured in superior cervical ganglion is not altered by CIH. Immuno-histochemical assay for MnSOD in cervical superior ganglia extracted from a sham (A and B) or a CIH exposed rat (D and E). Scale bar for A and D, 50 µm. Scale bar for B and E, 20 µm. Representative western blot (C) and quantification of immunoblot showed that CIH did not produce changes of MnSOD in homogenates of superior cervical ganglia. Student’s t-test, sham n=4, CIH n=5. Abbreviation: CIH, chronic intermittent hypoxia.
