[Tracheal phospholipid composition and respiratory distress syndrome of the newborn]
Abstract:
Tracheal or pharyngeal aspirates were collected in 50 newborn infants with and without respiratory distress syndrome (RDS). After lipid extraction the phospholipids were analyzed with 2-dimensional thin layer chromatography. Surface-active are lecithin (PC), phosphatidylglycerol (PG), and phosphatidylinositol (PI). Newborn infants with RDS always have a complete lack of PG, which makes up to 11% of phospholipid-phosphors in mature newborns. In all infants with and without RDS, a sharp increase of PC occurs in the lung effluent after birth. The recovery from RDS is characterized by marked changes of PI: this phospholipid rises up to twice its initial value if the infants survive. The PI-increase parallels the clinical improvement and reaches its maximum usually on the 5th day of life. At the time of the PI-peak, the infants' surfactant function is sufficient to maintain alveolar stability with spontaneous breathing. In infants dying from RDS the PI-increase was not observed.

Classifying Matter by Composition
According to its composition, the matter can be classified into two broad categories — pure substances and mixtures.
A pure substance is a form of matter that has a constant composition throughout with uniform properties. For example, any sample of sucrose has the same composition and same physical properties, such as melting point, color, and sweetness, regardless of the source from which it is isolated.
A mixture is composed of two or...

The Larynx
It is located between the pharynx and the trachea, acts as a passageway for air, and hosts several critical structures, such as the epiglottis, vocal cords, and glottis. The epiglottis acts as a gateway, guiding food to the...
