Diurnal variation of nasal protein concentration.
In normal subjects a marked diurnal variation was disclosed in the concentrations of immunoglobulin G (IgG), IgA and albumin in nasal secretion, the night values being 4.5-5.5 times higher than those during the day. It is suggested that this is due to changing secretory activity of the nasal glands.
