Anti-inflammatory, analgesic and choleretic effects of active fraction of Incavillea arguta (Royle) Royle
Objective,2,To study whether MTH, the active fraction of ,Incavillea arguta, (Royle) Royle, has anti-inflammatory, analgesic and choleretic effects and to observe whether its effect is better than that of the crude extract of ,Incavillea arguta,.,Methods,2,The mice formaldehyde pain test and mice hot plate test were used to study the analgesic condition of MTH and the crude extract of ,Incavillea arguta, (Royle) Royle, and the models of xylene-induced ear edema and the carrageenan-induced paw edema of mice were used to study the anti-inflammatory effect of MTH and the crude extract of ,Incavillea arguta, (Royle) Royle, and finally the gallbladder weight test in the mice and the gallstone samples collected from clinical patient were carried out to study its choleretic and stone-dissolving effect.,Results,2,①The analgesic test: compared with the model group, at 30 min, in hot plate test, medium and high dose groups of MTH could enhance the rate of pain threshold efficiency in mice (,P,<,0.05) ; and in mice formaldehyde pain test, medium and high dose of MTH could reduce the formaldehyde-induced pain score in the first phase and the second phase (,P,<,0.05,P,<,0.01) , and the analgesic effects were better than that of the crude extract of ,Incavillea arguta, (Royle) Royle. ②The anti-inflammatory test: compared with the control group, high, medium and low dose groups of MTH significantly inhibited xylene-induced ear edema in mice, and the inhibition rates were respectively 45.21%, 41.89%, 23.83% (,P,<,0.01,P,<,0.01,P,<,0.05) , and the inhibition rates of the crude extract of ,Incavillea arguta, (Royle) Royle was 16.64%, lower than that of the high and medium dose groups of MTH (,P,<,0.05) . Both medium and high dose groups of MTH could inhibit toe swelling in mice (,P,<,0.01,P,<,0.01).③The choleretic test: compared with distilled water group, high, medium and low dose groups of MTH and the crude extract of ,Incavillea arguta, (Royle) Royle could reduce the gallbladder weight of mice, promote bile excretion (,P,<,0.01) and choleretic effect of MTH was better than that of the crude extract of ,Incavillea arguta, (Royle) Royle, and high, medium and low dose groups of MTH and the crude extract of ,Incavillea arguta, (Royle) Royle could effectively dissolve cholecystolithiasis (,P,<,0.01) .,Conclusion,2,MTH has obvious analgesic, anti-inflammatory and choleretic effects, and the effect is better than that of the crude extract of ,Incavillea arguta, (Royle) Royle.
