Asthma is a chronic pulmonary disease that affects an estimated 235 million people worldwide. Anti-asthmatic drugs such as inhaled corticosteroids, leukotriene receptor antagonists, short/long-acting �?²2-agonists and anticholinergic drugs are used to treat asthma; however, they may cause serious adverse health effects. Opuntia humifusa (eastern prickly pear) has been used as a food and traditional medicine worldwide, however; its anti-asthmatic effects have not been reported. In this study, we evaluated O. humifusa as a potential therapeutic or preventive component of anti-asthmatic drugs. We divided ovalbuminsensitized mice into the following groups: Normal control, asthma-induced control, dexamethasone-treated group (positive control), 50 mg/kg O. humifusa-treated group, 100 mg/kg O. humifusa-treated group and 500 mg/kg O. humifusa-treated group. Levels of Th1/Th2/Th17-related cytokines were evaluated using RT-PCR, ELISA and immunohistochemistry. O. humifusa dose-dependently suppressed the morphological changes typically observed in asthma, such as goblet cell hyperplasia, inflammatory cell infiltration, mucous hyper-secretion and relative basement membrane thickening in the respiratory system. These results may be attributable to regulation of Th1-/Th2-/Th17-related factors, especially interleukin (IL)-4 and IL-13. We conclude that O. humifusa is a potential anti-asthmatic drug candidate.
