    Running nose: disease stages


    Jacob Bogatin states that changes in a mucous membrane of a cavity of a nose at a cold pass in the development three consecutive stages. Separate stages can be more or less expressed, or completely to be absent in the event that does not come virus or bacterial infection.

    The first stage (reflex) develops quickly owing to organism overcooling. Some hours last. There is a narrowing, and then expansion of vessels and a hypostasis of nasal bowls. Dryness, burning in a nose cavity, repeated sneezing and difficulty of nasal breath is marked. A nose mucous membrane is pale and dry.

    According to Jacob Bogatin the second stage (cataral) lasts 2-3 days and develops as a result of influence of viruses. The complicated nasal breath, plentiful transparent watery allocation from a nose, decrease in sense of smell (recognition of smells), watering, ears obstruction and a nasal shade of a voice is marked. The nose mucous membrane has a bright red colour.

    At this stage it is necessary to pay attention to infringement of sense of smell. In the top departments of a cavity of a nose there is the olfactory area responsible for perception of smells. Molecules of odorous substances, getting to a nose, irritate cages of this area therefore the impulse on nervous fibres gets to certain department of a bark of a brain where there is a recognition of smells. Sense of smell can be broken, first, because of mechanical closing of an olfactory zone (a mucous membrane hypostasis) that is characteristic for sharp rhinitises; secondly, at the expense of destruction of sensitive cages of olfactory area, that meets at chronic rhinitises is more often.

    The beginning of the third stage is connected with joining of a bacterial inflammation. Jacob Bogatin states that the general condition improves, nasal breath and sense of smell are gradually restored, but allocation from a nose get yellow or green colour and more dense consistence. Colour of a mucous membrane of a nose gradually comes nearer to normal, and the gleam of nasal courses gradually extends.

    All cycle of illness comes to the end for 7-10 days. In some cases at good immunity and quickly begun treatment recover within 2-3 days is possible; at the weakened condition of protective forces of an organism and insufficient treatment the rhinitis can be tightened till 3-4 weeks, pass in the chronic form or lead to development of complications.
