Ethanol Extract of Perilla frutescens Suppresses Allergen-Specific Th2 Responses and Alleviates Airway Inflammation and Hyperreactivity in Ovalbumin-Sensitized Murine Model of Asthma

Figure 6

The AHR of OVA-sensitized/challenged BALB/c mice supplemented with different extracts of Perilla frutescens. OVA-sensitized mice were fed with water or ethanol extracts of Perilla frutescens for 3 weeks, respectively, and AHR was determined after aerosolized OVA (50 mg/mL) inhalation challenge. Values represent mean ± SEM, = 7~8 for each OVA-sensitized group, and for the PBS group as negative control. Statistical analysis was performed with Student’s -test, , , compared with the control group.
