Abstract

Stress exacerbates allergic disorders such as atopic dermatitis and asthma. It is also an important factor affecting blood flow (BF). Allergic reactions also affect blood flow. For example, we observed that mice sensitized with hen egg-white lysozyme (HEL) have decreased BF during the allergy induction phase. Based on this finding, we established a model for evaluating chronic restraint stress-enhanced allergies. Mice were sensitized with 12.5โ€‰ยตg/head of HEL on day 0, then restrained for 90โ€‰min daily on days 1-3, 5, and 6 in a modified 50โ€‰mL polystyrene conical centrifuge tube with multiple air holes for ventilation. We used the decrease in BF during that time as a guide for developing an in vivo assay for substances that can inhibit stress-enhanced allergies. Finally, we demonstrated the utility of the new method by testing crude drugs that are used solely or in combination with other crude drugs to treat stress-related illness and neuropsychiatric symptoms. Our model should be useful for identifying potential anti-stress-enhanced allergy drugs.
