Anti-nociceptive and Anti-inflammatory Effect of an Ethanol Extract Mixture of Vitis amurensis, Aralia cordata, and Glycyrrhizae radix KCI 등재
pp.60-66
Vitis amurensis, Aralia cordata, and Glycyrrhizae radix have been widely used in Korea, China, and Japan because of their anti-oxidative and anti-inflammatory activities. The present study investigated the anti-nociceptive and antiinflammatory properties of an ethanol extract (SSB) of a mixture of three medicinal plants of Vitis amurensis (stem and leaf), Aralia cordata (stem and leaf), and Glycyrrhizae radix. Anti-nociceptive activity was determined using chemical (acetic acid and formalin) and thermal (hot plate) stimuli-induced algesia tests. Formalin-induced paw edema was evaluated for anti-inflammatory activity. SSB (25–100 mg/kg, p.o.) and ibuprofen (100 mg/kg, p.o.), a positive nonsteroidal anti-inflammatory drug (NSAID), significantly inhibited the acetic acid-induced writhing response caused by peripherally mediated algesia, but failed to protect thermal nociception in the hot plate test that was employed for centrally mediated analgesic activity. However, morphine (5 mg/kg, s.c.) used as a positive opioid control alleviated the acetic acid-induced writhing response and thermal nociception in the hot plate test. In the formalin test, SSB (50 and 100 mg/kg, p.o.) inhibited the second phase response (peripheral inflammatory algesia), but not the first phase response (central algesia), whereas morphine inhibited both phases of the pain response. Both SSB (25-100 mg/kg, p.o.) and ibuprofen (200 mg/kg) caused significant reduction of the formalin-induced increase of paw thickness, which was the index of inflammation. These results suggest that SSB has a significant anti-nociceptive activity that seems to be peripheral, but not central. SSB also displays antiinflammatory activity in an acute inflammatory model. The present study supports a possible use of SSB to treat pain and inflammation.
