ABSTRACT
Anti- inflmmatory effects of ferulofen(FL)and its mechanisms were studied. In the rat carrageenin pleurisy, FL produced a dose-related reduction of exudate volume, protein contents and leucocyte numbers in the exudate. FL also reduced activity of ?-glucuronidase in the exudate only in higher dose 3 h after carrageenin. These results suggest that FL has a marked anti-inflammatory action and its mechanisms may be similar to indomethacin. Ia vitro, FL caused a dose-dependent inhibition of hydrogen peroxide release from rat peritioneal macrophages ( M0 ) stimulated by opsonized zymosan. It suggested that its anti-inflammatory mechanisms may also relate to inhibitting cell activation. ?-receptor agonist ( Isoproterenol, ISO), in a ineffective dose, synergized with FL in inhibitting M H2O2 release and the synergic mechanism remains to be established.
ABSTRACT
Ferulof en ( FL, 45mg and 200mg/kg im ) showed marked antipyretic effect on rabbit fever induced by typho-paratyhoid vaccine and on rat fever induced by yeast powder suspension respectively. Their potency and action phase were similar to those of aspirin ( 35mg and 100mg/kg) . Furthermore, it blocked the action potential of sciatic nerve in toad to some extent and had a certain local anesthetic effect on guinea pigs in intradermic wheal test, but much weaker than procaine and lidocaine at the same concentration. It had no obvious influence on corneal reflex in rabbits.It can be concluded from these findings that together with the results of previous paper the findings of this paper further indicated FL may be proved to be a new antiinflammatory, antipyretic and analgesic drug.
ABSTRACT
Antiinf lammatory effects of Ferulofen ( FL ) were shown by im or ip on xylene-induced swellingof mice ear, carrageenin produced edema of hind paw in rats, and decreased volume of pleural exud- ate on carrageenin-induced acute pleurisy of rats, FL also inhibi-tied the proliferating granuloma by croton oil. The above dose r-ange in 50-100mg/kg im or ip which presented a good dose-effect relationship, FL also inhibited the mice writhing caused by H AC & tail-flick response to 1 light irradiation, suggesting its strong analgesic effect. In addition, its anticancer effect in vitro ( carcinoma of Ehlrich ascitis)was better than that in vivo ( Sl80 sarcoma) in mouse. So FL may be considered to be a promising new type of non-steroidal antiinflammatory & anticancer drug ,worthy of further reseaching & exploring in the future.
