Abstract:
Objective To optimize the screening methods for antiallergic activity of two Chinese medicines in vitro and compare the antiallergic activity of five medicine pairs in vitro.Methods The degranulation assay of RBL-2H3 cells was optimized,and the activity of the five drugs on inhibiting mast cell degranulation was compared by toluidine blue staining and the release of β-HEX and histamine(HIS).The hyaluronidase inhibition test was optimized to compare the hyaluronidase inhibition effect of five Chinese medicine pairs.Results In the experiment of degranulation of RBL-2H3 cells,5 medicine pairs could inhibit β-HEX release from model cells to different degrees(P<0.05),including Schizonepetae Herba-Saposhnicovia divaricata,Ephedrae Herba-Asarum,Saposhnicovia divaricata-Radix Angelicae dahuricae,Rhizoma Chuanxiong-Asarum.The β-HEX release rate in the supernatant of degranulated model cells was significantly increased(P<0.05)after coculture with Flos Magnoliae-Fructus Xanthii.All the five medicine pairs could reduce HIS release in the supernatant of degranulated model cells.In the hyaluronase inhibition rate test,the hyaluronase inhibition rate of each medicine pair was Rhizoma Chuanxion-Asarum>Saposhnicovia divaricate-Radix Angelicae dahuricae>Schizonepetae Herba-Saposhnicovia divaricate>Ephedrae Herba-Asarum,among which Rhizoma Chuanxiong-Asarum had the strongest anti-allergic activity.Conclusion The trend of antiallergic activity of different drugs obtained by the two methods is consistent in vitro,indicating that the two methods can be used for screening antiallergic activity in vitro.
