Kefir is a microbial symbiont mixture that produces jelly-like grains. As a widely used neutraceutical, however, the therapeutic applicabilityof kefir is not certain. In order to investigate the pharmacological effects of kefir, we used a mouse asthma model, in which airway inflammation and airway remodeling was produced by ovalbumin sensitization and challenge. BALB/c mice sensitized and challenged to ovalbumin, were treated with kefir (50 mg/kg administered by intra-gastric mode) 1 h before the ovalbumin challenge. Kefir significantly suppressed ovalbumin-induced airway hyper-responsiveness (AHR) to inhaled methacholine. Intra-gastric administration of kefir significantly inhibited the increase in the total inflammatory cell count induced by ovalbumin, and the eosinophil count in bronchoalveolar lavage fluid (BALF). Type 2 helper T cell (Th2) cytokines, such as interleukin-4 and interleukin-13, and total immunoglobulin E (Ig E) levels, were also reduced to normal levels in bronchoalveolar lavage fluid. Histological studies demonstrate that kefir substantially inhibited ovalbumin-induced eosinophilia in lung tissue and mucus hyper-secretion by goblet cells in the airway. Kefir displayed anti-inflammatory and anti-allergic effects in a mouse asthma model and may possess new therapeutic potential for the treatment of allergic bronchial asthma.
