this inhibition could be explained , in part , by generalized inhibition of total protein synthesis , but in addition , there was a significant inhibition of prolyl hydroxylation during collagen biosynthesis , as indicated by a reduction in the ratio of [ 3h ] hydroxyproline/ ( [ 3h ] hydroxyproline + [ 3h ] proline ) .
