A Phenotypic changes in CTLs; B polyphenol oxidase (PPO) activity; C peroxidase (POD) activity; D phenylalamine ammonia lyase (PAL) activity; E lipoxygenase (LOX) activity. Data in the graphs are expressed as the mean ± SEM, and different letters indicate statistically significant differences of p < 0.05Back to article page
