Figure 1From: Distinct compartmentalization of SP-A and SP-D in the vasculature and lungs of patients with idiopathic pulmonary fibrosis Surfactant protein (SP)-A and SP-D levels in bronchoalveolar lavage fluid (BALF). (A) There was no significant difference in SP-A levels between patients and healthy subjects (HS). (B) The SP-D levels were significantly lower in idiopathic pulmonary fibrosis (IPF) patients than in healthy subjects (P = 0.003) and sarcoidosis patients (SAR; P = 0.003).Back to article page
