体内研究
Albiflorin (50 mg/kg; intraperitoneal injection; once a day; for 15 days; Wistar rats) treatment significantly increases the paw withdrawal threshold (PWT) on the 11th and 15th day after surgery in rats. Albiflorin could inhibit the activation of p38 MAPK pathway in spinal microglia and subsequent upregulated IL-1β and TNF-α. Albiflorin displays remarkable effects on inhibiting the activation of astrocytes, suppressing the overelevated expression of phosphorylation of c-JNK (p-JNK) in astrocytes, and decreasing the content of chemokine CXCL1 in the spinal cord.
