Lingguizhugan decoction significantly enhanced the viability of SH-SY5Y cells with amyloid-β peptide-induced injury, and lowered levels of interleukin-1β, interleukin-6, tumor necrosis factor-a and nitric oxide in the culture supernatant of activated BV-2 microglia. The effects of 103 g/mL Lingguizhugan decoction were more significant. These results suggest that Lingguizhugan decoction can protect SH-SY5Y cells against amyloid-β peptide （25-35）-induced injury in a dose-dependent manner by inhibiting overexpression of inflammatory factors by activated microglia.展开更多

The rats were treated with Daiqin phlegm-expelling pill at the indicated doses for 28 d, the inflammatory cells in bronchoalveolar lavage fluid(BALF), the concentration of tumor necrosis factor-α(TNF-α), interleukin(IL)-8 and IL-6 in blood and the inflammation in lung were evaluated.RESULTS: The number of inflammatory cells in the BALF and TNF-ficantly redα, IL-8 and IL-6 level in plasma were signiuced in rats with COPD when treated with Daiqin phlegm-expelling pill or ambroxol hydrochloride tablet, compared with those without any treatment. The Daiqin phlegm-expelling pill treated rats with COPD had a attenuated inflammation in lung tissue, compared with the untreated group.CONCLUSION: Daiqin phlegm-expelling pill can significantly restrain the airway inflammation in rats with LPS-smoke induced COPD.展开更多
