IgE antibody to parasite induced in mice.

Abstract

internum in visual control with a head lamp and a nasal speculum (4). The subjective sensations of nasal patency were registered with a visual analog scale (VAS) from 0 (totally open) to 10 (totally obstructed). The measurements took place at 20-min intervals during short interruptions in the exposure. Nasal secretion: The median amounts of the nasal secretions from both nasal cavities began to increase during the resting period in the cold (Fig. 1), the increase being statistically signi®cant (P=0.031, Wilcoxon test for paired comparisons). During the exercise in the cold, the secretions further increased (P=0.031). Nasal volume and ow. Slight, statistically nonsigni®cant average increases in the total nasal ow and volume were noted during the resting period in the cold when compared with the pre-exposure values (Fig. 1). During the exercise, the increases were statistically signi®cant both in the ow (P=0.046) and in the volume (P=0.021). Contralateral comparison of ow and volume changes. The ow and volume changes between the pre-exercise resting periods at +228C and ±118C were compared in the initially more open and less open cavities (Fig. 1). Statistically signi®cant increases in the less open cavities were noted both in the ow (P=0.006) and in the volume (P=0.015). In the more open cavities, nonsigni®cant average decreases in ow and volume were were noted. Subjective sensations of nasal patency. All subjects evaluated their noses as patent (VAS 0±3) throughout the experiment. No signi®cant average patency changes could be noted in the cold exposure, either during the resting periods or during the exercise. We conclude that in a cold environment unilateral adjustments in nasal congestion take place, maintaining the total nasal patency. Therefore, the lower airways are protected better than if oral breathing were to take place in these circumstances. The IgE antibody to parasite induced in mice
