  • Title: Action of Rubus coreanus extract on systemic and local anaphylaxis.
    Author: Shin TY, Kim SH, Lee ES, Eom DO, Kim HM.
    Journal: Phytother Res; 2002 Sep; 16(6):508-13. PubMed ID: 12237805.
    Abstract:
    The effect was investigated of the aqueous extract of Rubus coreanus Miq. (Rosaceae) fruits (RCAE) on systemic and local anaphylaxis. RCAE (0.01-1 g/kg) dose-dependently inhibited systemic anaphylaxis induced by compound 48/80 in mice. RCAE (1 g/kg) also significantly inhibited local anaphylaxis activated by anti-DNP IgE. Pretreatment with RCAE at the same concentration before systemic anaphylaxis reduced the plasma histamine levels in a dose-dependent manner. RCAE (0.001-1 mg/mL) dose-dependently inhibited the histamine release from rat peritoneal mast cells (RPMC) activated by compound 48/80 or anti-DNP IgE. The level of cAMP in RPMC, when RCAE was added, significantly increased, compared with that of the normal control. Moreover, RCAE (0.01-1 mg/mL) had a significant inhibitory effect on anti-DNP IgE-induced tumour necrosis factor-alpha production from RPMC. These results indicate that RCAE may possess antianaphylactic action.
