摘要
目的 探讨偏热环境下气流刺激对人体免疫球蛋白浓度的影响,并讨论分析免疫球蛋白浓度与主观问卷结果间的相关性.方法 在人工气候实验室通过改造后的吹风装置营造不同模式的动态气流,测量12名受试者暴露在不同气流环境中的S-IgA和S-IgE浓度变化,并同时调研受试者的TSV、TCV、吹风感、气流满意度和气流不适症状投票.结果 偏热环境中吹风后S-IgA浓度升高了56.3%,但后续的高风速工况反而导致S-IgA浓度降低了24.8%;S-IgA和S-IgE均在TSV中性时浓度最高,S-IgA浓度在舒适时比不舒适时高176%;S-IgA浓度与平均风速呈倒"U"型关系,且当平均风速为1.0 m/s时,S-IgA浓度最高.结论 气流运动对S-IgA浓度存在显著影响,但对S-IgE浓度的影响不大,偏热环境中较为舒适的吹风有利于提高S-IgA浓度,增强呼吸系统免疫力,但风速过高引起的强吹风感以及不满意的气流环境会导致S-IgA浓度降低.
Abstract
Objective To explore the effects of airflow stimuli on human immunoglobulin concentrations in a warm environment,and to discuss and analyze the correlations between immunoglobulin concentrations and subjective questionnaires results.Methods Dynamic airflow of different modes was created by a modified wind blowing device in the climate chamber.Then the changes of S-IgA and S-IgE concentrations of 12 subjects exposed to different airflow environments were measured,during which the TSV,TCV,draught perception,satisfaction with the airflow,and airflow discomfort symptom polling of the subjects were investigated.Results The S-IgA concentration increased by 56.3%after blowing in the warm environment,but the subsequent high air speed condition resulted in a decrease of S-IgA concentration by 24.8%.Both S-IgA and S-IgE had the highest concentrations when the TSV was neutral,and the S-IgA concentration was 176%higher under comfortable conditions than that under uncomfortable conditions.The S-IgA concentration showed an inverted"U"-shaped relationship with the average wind speed,and the highest S-IgA concentration was observed when the mean air speed was 1.0 m/s.Conclusion Dynamic airflow has a significant effect on S-IgA concentration but little effect on S-IgE concentration.Comfortable airflow in a warm environment could benefit the S-IgA concentration elevation thus the respiratory immunity.However,a strong draught perception caused by high wind speeds and an unsatisfactory airflow environment can lead to lower S-IgA concentrations.
