[The involvement and reparative regeneration of the mucosa of the airways in thermal inhalation trauma in burn patients].

The adaptive reorganization in mucosa of the upper airways was investigated in 15 burned patients during the first 24 days postburn using historadiography in vitro. The fibreoptic bronchoscopic biopsy specimens obtained in vivo were analysed. The initial significant destructive changes in mucosa and inhibition of DNA and RNA synthesis in the epitheliocytes were changed at day 8 postburn by the development of consecutively arising regenerative processes.

[Ultrastructural characteristics of epidermocytes cultured on media with a standard concentration of calcium ions and on hypocalcic media].

A study was made of the ultrastructural changes of epidermocytes cultured on hypocalcic media (Ca2+ content below 0.08 mM) in comparison with epidermocytes, cultured on media with standard Ca2+ content (1-2 mM). A detailed description of methods for epidermocyte cultivation and data of electron microscopic cell research is presented.
