Changes in the lung alveolar proteins in some experimental conditions.
The Authors have directed their research to the alveolar lining (the surfactant) proteins and they have particularly studied its alterations in shock pathological conditions. Some rats have been subjected to haemorrhagic and toxic shock, by Escherichia Coli's lipopolysaccharide; then lung washing has been performed and on extracted liquid proteins have been studied by two-dimensional immunoelectrophoresis (TDI). The obtained data have been encouraging and very useful for studies process.
The proteins of the lung alveolar lining.
The protein composition of the lung washing has been analysed by immunochemical methods: it has been possible to demonstrate the presence of many proteins, mainly albumin, immunoglobulins and beta-globulins, some of them seem laying in the alveolar lining and having the function of stabilizing the surfactant system.
[Use of a new selective stain for demonstrating the vagal fibers in gastric surgery. Experimental study].
Scalar concentrations (0.4%-0.2%-0.1%-0.05%) of methylene blue in a 7.02% ascorbic acid solution have been used in animals and humans for visualizing vagal branches at gastric level. These solutions constitute a simplified variation of Lee's test and the most effective for determining vagal fibres proved to be the 0.1% concentration.
