6、sed on myeloid cells (TREM-1) and endotoxin, while the serum level of IL-10 is up-regulated and myeloperoxidase (MPO) in lung, liver and small intestine is reduced 1. Forsythoside B atdoses higher than 8 mg/kg produces a significant neuroprotective potential in cerebral ischemia andreperfusion rats.

7、 Forsythoside B (20 mg/kg) demonstrates significant neuroprotective activity even afterdelayed administration at 1 h, 3 h and 5 h after cerebral ischemia and reperfusion. Forsythoside B 20 mg/kgattenuates histopathological damage as demonstrated by smaller brain infarct size and brain edema,decrease
