The structure of the Langmuir purple membrane (PM) monolayer was studied by scanning tunneling microscopy (STM). The topography of both the external and cytoplasmic sides of the monolayer was investigated. The thickness of the PM monolayer was determined to be about 4 nm. PM films include specific oval 'crater'-like structures of 50-60 nm in diameter.

On the basis of the analysis of 1023 clinical observations of hemorrhagic shock in acute gastric hemorrhage, the modern notions about the mechanisms of its development, peculiarities of the clinical course, depending on nature and volume of blood loss are stated. A scheme for intensive anti-shock therapy has been developed. The lethality after 1892 emergency operations was 3%, and in ulcer with hemorrhagic shock after 547 operations--9.3%.
