Effect of apple phenols on anxiety/depression in a rat model of acute exacerbation of chronic obstructive pulmonary disease

Figure 2 Compare lung function indicators of different groups of rats. A: Peak expiratory flow; B: Peak inspiratory flow; C: Forced expiratory volume in 0.3 seconds to forced vital capacity ratio. ^aP < 0.01 vs control group, ^bP < 0.05 vs model group, ^cP < 0.01 vs model group, ^dP < 0.05 vs low-dose apple polyphenols (AP), ^eP < 0.05 vs middle-dose AP,^fP < 0.05 vs high-dose AP. PEF: Peak expiratory flow; PIF: Peak inspiratory flow; AP-L: Low-dose apple polyphenols; AP-M: Middle-dose apple polyphenols; AP-H: High-dose apple polyphenols; AP-H + mcc950: High-dose apple polyphenols + NOD-like receptor protein 3 inhibitor.
