The total collagen content of the left lung was determined by measuring hydroxyproline content in aliquots of pulverized left lung as described previously.    From Wordnik.com.  [PLoS ONE Alerts: New Articles] Reference

In contrast, HPLC determination of hydroxyproline content, as a surrogate marker for collagen protein levels, demonstrated no significant differences between the bleomycin groups - in agreement with the Ashcroft scores.    From Wordnik.com.  [PLoS ONE Alerts: New Articles] Reference

As a clarification of the above, molecular oxygen, as I understand it, is necessary for the post-transcriptional hydroxylation of proline to hydroxyproline - ie the oxygen in the hydroxyproline does not come from water, but is added from an O2 molecule by an oxygenase enzyme.    From Wordnik.com.  [ScienceBlogs Channel : Life Science] Reference
