SP-B is essential for the ability of surfactant to reduce surface tension (Nogee, 2004), and SP-C has recently been shown to bind lipopolysaccharide (LPS) (Augosto et al., 2002; Augosto et al., 2003). In the absence of surfactant, surface tension is extremely high at end expiration and tends to collapse the lung. This makes breathing difficult to the extent that respiration is frequently impossible without ventilatory support and surfactant replacement. A deficiency of surfactant – which can result in “Respiratory-Distress Syndrome (RDS)” – occurs when infants are born prematurely, before their surfactant biosynthetic machinery has matured. Treatment of these premature infants with exogenous surfactant replacement reduces mortality and morbidity, because of this disease (Wright, 2005).

SP-B is essential for the ability of surfactant to reduce surface tension3, and SP-C has recently been shown to bind lipopolysaccharide (LPS)4,5. In the absence of surfactant, surface tension is extremely high at end expiration and tends to collapse the lung. This makes breathing difficult to the extent that respiration is frequently impossible without ventilatory support and surfactant replacement. A deficiency of surfactant — which can result in RESPIRATORY-DISTRESS SYNDROME — occurs when infants are born prematurely, before their surfactant biosynthetic machinery has matured. Treatment of these babies with exogenous surfactant replacement (BOX 1) reduces mortality and morbidity due to this disease.

Anmerkungen

The source is given, but the extent of the copied text is not clear to the reader. Neither is it clear that the copy is almost literal. Also three references to the literature are taken from the source.
