Product details
Analgesia: It has obvious analgesic effects on a variety of pain models, including electric stimulation, hot plate method, photothermal stimulation and acetic acid twisting method caused by the pain response in mice. Its pathways of action include analgesic effects on the centre and inhibition of prostaglandin synthesis and release.
Anti-inflammatory: It can significantly reduce the increase of vascular permeability induced by 5-HT, and has obvious inhibitory effect on the swelling of the toe of rats induced by carthamus tinctorius. It has obvious improvement effect on rat adjuvant arthritis model and can significantly reduce the systemic lesions in rats.
Immunomodulation: It has significant inhibitory effect on the synthesis of cytokines IL-1, IL-2, IL-6 and TNF by human peripheral blood mononuclear cells, significantly reduces phagocytosis rate of mouse macrophages, and significantly inhibits the synthesis of inflammatory mediators PGE2, LTC4 and Nitrogen oxides. It has anti-T-lymphocyte proliferation and synovial membrane proliferation effects, and can inhibit the body's immune rejection reaction.
Sedation: it can significantly reduce the spontaneous activity of mice, and has no significant effect on the sleep time of barbiturates, and has an antagonistic effect on strychnine, but cannot oppose pentamethylene tetrazolium. Dogs and monkeys orally administered with 45-95mg/kg of the drug also have obvious sedative effects, and can eliminate the ‘irritation’ reaction induced by electrical stimulation in mice.
