方法： 用热板法和电刺激嘶叫法分别测定小鼠和大鼠的痛阈。
Methods: The hot plate test in mice and tail stimulation vocalization test in rats were used.
采用热板法测痛阈，取血测凝血时间，取脑匀浆测五羟色胺(5 - HT)。
Pain threshold was determined by hot plate method, coagulation time of blood and 5-ht were determined.
对于热板法所致的疼痛，三冬茶可明显提高痛阈，最高可提高痛阈43.8%。
Trilex could obviously enhance the threshold of hot plate induced pain in mice. The maximum threshold increased 43.8%.
