This study manufactured hydrogel, which was contained NSAIDs(non-steroidal anti-inflammatory drugs) Ketorolac tromethamine and hydrolyzed products of gardeniae fructus extract, and experimented viscosity, surface tension, tensile strength and bio-adhesiveness by using hairless mouse. Thus, it was performed in expectation for being probably able to develop as effective auxiliary agent of periodontal disease after non-surgical or surgical periodontal treatment. As a result, the following conclusions were obtained. 1. Out of KGE and KGH gel materials, the content of ketorolac tromethamine was 1.02~0.97%. The content of geniposide was 0.34% in KGE gel A and C. However, it got lower to 0.11% in KGH gel B and D. The content of genipin wasn’t shown in KGE gel A and C, but was shown with 0.13% in KGH gel B and D. 2. As for viscosity according to temperature in gel material, the gel, which used independently Carbopol 940 as gel inoculant, maintained the higher viscosity than the gel, which added Poloxamer 407. The surface tension in each material showed 34.77~40.58 dyne/cm at 37. As for tensile strength in material, KGH gel B was shown the higher tensile strength in about 3.5 times compared to the control group. 3. As for bio-adhesiveness, the back-skin upper part(epidermis) and abdomen skin were shown to be 50.62 N in KGH gel B, thereby having indicated higher value in about 5 times compared to control group. The back-skin lower part(dermis) and abdomen skin were shown to be 35.93 N in KGH gel B, thereby having indicated higher value in about 3.5 times compared to control group.
