DAI Jihong, et al. Effects of house dust mite injected in neonate rats on airway inflammation and TH subset in later life[J]. Journal of Chongqing Medical University, 2004,(3):299-301. DOI: 10.13406/j.cnki.cyxb.2004.03.014.
Objective:To study whether early exposure to house dust mite will aggravate airway inflammation as well as the onset of asthma and to explore the relevant mechanism.Methods:Neonate Wistar rats were injected with HDM subcutaneously instantly after birth.After the four times management
they were established as models of asthma with OVA
and bronchoalveolus was lavaged to count percentage of eosinophils.And levels of IL-4
IFN-γ and serum OVA-IgE were also detected.Results:In HDM group
the percentage of EOS
level of serum OVA-IgE and level of IL-4 were (37.07±1.10) %
(0.20±0.023) and (78.96±12.18) pg/ml
respectively
the highest among the three groups
otherwise level of IFN-γ
the lowest
(93.78±2.10)pg/ml.Conclusion:Early exposure to house dust mite after birth could aggravate the level of airway inflammation in later life and increase the level of IgE
