One of essential functions of mucous gel is protection of tissues against dehydration (drying). In order to fulfil this function, the mucous gel should be strongly hydrated, i.e. it should contain a large amount of water. The presence of the large amount of water prevents strong changes of water activity in the mucous gel when the relative humidity (RH) of the surrounding atmosphere changes. Nonetheless, when subjected to a long contact with dry atmosphere, mucous gel dries out. Under 30% RH, the eyes and skin become dry, and under 10% RH the nasal mucous membrane becomes dry. Dehydration of mucous gel changes its protective properties and may become a pathogenic factor in many diseases. In this project we investigate how the structural, rheological, transport and microbiological properties of mucous gel are affected by hydration.
