title: Effects of epinephrine, indomethacin, acetylsalicyclic acid, dexamethasone, and cyclic AMP on the in vitro activity of lysosomal hyaluronidase from the rabbit iris.
abstract: 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.
