Action Of Rubus Coreanus Extract On Systemic And Local Anaphylaxis
PHYTOTHERAPY RESEARCH(2002)
摘要
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. Copyright (C) 2002 John Wiley Sons, Ltd.
