Perhaps you should try some spelling variations:
pulmonary objects » pulmonary effects (Expand search), pulmonary spect (Expand search), primary objects (Expand search)
release pulmonary » decrease pulmonary (Expand search), disease pulmonary (Expand search), related pulmonary (Expand search)
decrease drugs » disease drugs (Expand search), release drugs (Expand search), increase drug (Expand search)
drugs release » drug release (Expand search), drugs reverse (Expand search)
in decrease » in decreased (Expand search), on decrease (Expand search), pain decrease (Expand search)

You may be able to get more results by adjusting your search query.

• The words AND, OR and NOT may confuse the search; try adding quotes: "(( decrease in decrease OR decrease ) OR ( decrease drugs release pulmonary objects ))~".
• Adding a wildcard symbol may retrieve word variants: (( decrease in decrease OR decrease ) OR ( decrease drugs release pulmonary objects ))*.
