Abstract

To study airway reactivity and impulse oscillation (IOS)-measured airway resistance indicators of residents of Zhenhai industrial area in Ningbo city. In the form of follow-up, both. airway reactivity and respiratory functions of populations in Zhenhai industrial zone (n = 215) and urban (n = 203) were measured, comparing difference degree between different regions. Ninty-five of 215 cases in industrial area were identified as suspected airway hyperresponsiveness, but only 43 of 203 cases were in urban areas. Forty-seven of 95 cases (49.5%) in industrial zone were positive, while only 14 cases (32.6%) in urban. The proportions of people in the two regions on different types of airway hyperresponsiveness were significantly different (P < 0.01). All airway resistance indexes of urban populations were significantly lower than that of industrial zone (P < 0.05). The prevalence of airway hyperresponsiveness and IOS airway resistance aspects of industrial area residents was higher than that of urban residents. Monitoring and evaluating the airway diseases, inflammatory lesions and respiratory function in the region were good for understanding the severe pollution in the local area in certain significance.

Asthma

This feed focuses in Asthma in which your airways narrow and swell. This can make breathing difficult and trigger coughing, wheezing and shortness of breath.

Allergy and Asthma

Allergy and asthma are inflammatory disorders that are triggered by the activation of an allergen-specific regulatory t cell. These t cells become activated when allergens are recognized by allergen-presenting cells. Here is the latest research on allergy and asthma.
