The effects of epinephrine, indomethacin, acetylsalicylic acid, dexamethasone, and cyclic AMP on lysosomal hyaluronidase activity in in the rabbit iris were studied in vitro. Indomethacin and acetylsalicylic acid inhibited the lysosomal hyaluronidase activity. Dexamethasone and cyclic AMP (adenosine-3',5'-cyclic monophosphate) had little effect on the enzyme activity. Epinephrine activated the enzyme activity. These drugs had no effect on the activities of either bovine testicular hyaluronidase or rabbit iridial acid phosphatase. The possible role of lysosomal hyaluronidase in the rabbit eye and the drug effects were considered.

In this study, effects of rofecoxib, celecoxib, nimesulide on the acute phase of inflammation were studied in the carrageenan-induced paw edema model and their influence on the chronic phase of inflammation was evaluated in the cotton pellet granuloma tests. Additionally, effects of these drugs on capillary vascular permeability were examined in the hyaluronidase test and were compared with that of indomethacin (nonselective COX inhibitor). The results of the study demonstrated that rofecoxib, celecoxib, nimesulide, indomethacin at a dose of 10 mg kg(-1) reduced the volume of paw edema by 40.6% (p < 0.05), 21.6% (p < 0.05), 20.3% (p < 0.05), 64.0% (p < 0.05), respectively. Anti-proliferative effect of rofecoxib was of 29%, while those of celecoxib and nimesulide were of 13.5 and 21.2%, respectively. Indomethacin had an anti-proliferative effect of 44.2%. When the drugs were given at a dose of 25 mg kg(-1) rofecoxib, celecoxib, nimesulide reduced carrageenan-induced paw edema by 50.6% (p < 0.004), 27.9% (p < 0.004) and 33.0% (p < 0.004), respectively. Positive control, indomethacin, reduced the paw edema by 86.1% (p < 0.004). As a result, indomethacin, rofecoxib, celecoxib, nimesulide significantly inhibited both acute and chronic inflammation. While indomethacin, celecoxib, nimesulide significantly reduced capillary vascular permeability, the effect of rofecoxib was insignificant. We could not clarify this observation. Further studies are required to enlighten this effect of rofecoxib.

In this study the effects of compound B1, bis(3-aryl-3-oxo-propyl)methylamine hydrochloride, and an anti-inflammatory drug, indomethacin, were tested by carrageenan-induced paw edema and cotton pellet granuloma tests, for effects on acute and chronic phases of inflammation, respectively. Their effects on vascular permeability were also determined by hyaluronidase-induced capillary permeability test. Anti-inflammatory activity of B1 was compared with indomethacin. B1 decreased the carrageenan-induced paw edema by 49%, 35%, and 47% at 50, 100, and 200 mg kg(-1) doses, respectively, while this decrease was 82% by indomethacin at 20 mg kg(-1) dose. Antiproliferative effects in cotton pellet test of B1 at 50 mg kg(-1) and indomethacin at 20 mg kg(-1) doses were 44% and 43%, respectively. Indomethacin but not B1 inhibited the hyaluronidase-induced increase in capillary permeability. Our results suggest that B1 inhibits both acute and chronic phases of inflammation probably by an effect not mediated by prevention of increased capillary permeability. Especially, its anti-inflammatory activity against chronic phase of inflammation was comparable with that of indomethacin. Further detailed studies are needed to clarify the mechanism(s) of action responsible for the anti-inflammatory activity of B1.
