Administration of LBP In Vivo
LBP was purified from Lycium barbarum, which was harvested in Ningxia province of China. The preparation for LBP extracts was performed as reported previously (Yu et al., 2005). LBP was dissolved in PBS at dose of 4 mg/mL according to previous study (Li et al., 2013). LBP (20 mg/kg body weight) was administrated intragastrically with an oral gavage needle to the rats according to methods used in previous research (Wang T. et al., 2014). Standard chow diet and tap water were freely available to all rats.
