  • Both SCC 12 and SCC 13 cell lines were derived from squamous cell carcinoma (SCC) of the skin (Wu and Rheinwald, 1981). In the present study, we compared the inherent invasive activity in their raft cultures where most in vivo characteristics of epidermis can be reproduced by cell culture method. The raft culture of SCC 12 cell line produced many invading colonies within the collagen lattice and basal-like cells in the middle of differentiating cell layers, but no invasive activity was observed in the SCC 13 raft culture. We investigated which factors are implicated in inherent invasive activity of SCC 12 cell line by examining basal levels of type I collagenase, EGF receptor, fibronectin, and its receptor in two cell lines. Among them, only type I collagenase was significantly higher in invasive SCC 12 cells than in non-invasive SCC 13 cells. Furthermore, we tried to investigate mechanisms underlying between SCC 12 cell's inherent invasive activity and its high basal level of type I collagenase. As one of them, discrepancy in TGF alpha mediated responses between two cell lines was observed. In SCC 13 cells, TGF alpha initially stimulated type I collagenase at 12 h after TGF alpha treatment and then its down regulation was followed from 24 h even though TGF alpha was continuously present in the medium. However in SCC 12 cells, TGF alpha continuously stimulated type I collegenase up to 48 h. We propose that defect in EGF receptor's down-regulation may be involved in lack of type I collagenase's down-regulation and its possible connection to invasive activity of SCC 12 cell line.

  • Purpose: The purpose of this study is to induce artificial arthritis on rabbit TMJ by injecting collagenase. Materials and Methods: An experimental animal model of arthritis induced by surgical method or intraarticular injection of chemical agent like LDH, papain, ketorolac. Surgical method is complex and needs a long time in inducing arthritis. Intra-articular injection of chemical agent like LDH, papain, ketorolac is simple. But chemical agent like LDH, papain, ketololac needs multiple injections to induce arthritis and mechanism inducing arthritis was known. Collagenase destroys helical domain of type II collagen in extracellular matrix produced by chondrocyte and then induces arthritis. We injected collagenase (0.5, 1.0, 2.0 mg) into the temporomandibular joint of rabbit. In the control group saline was intra-articularly injected. The condylar cartilage, disk and synovia were histologically examined at 1, 2, 4, 6 weeks after the initiation of collagenase injections. Results: Four weeks after injection of 2.0 mg collagenase, we could see histologic change like arthritis. In other groups, we couldn't see arthritis-like change. Conclusion: In our study, we produce arthritis on temporomandibular joint of rabbit by using injection of collagenase in temporomandibular joint of rabbit. And this experimental osteoarthritis is a useful animal model.

  • 목적 : Collagenase-induced osteoarthritis(OA) 동물 모델에서 전침의 adrenergic mechanism을 연구하고자 한다. 방법 : Collagenase-induced arthritis(CIA)를 유발하기 위하여 5주령의 male Sprague-Dawley rat의 뒷다리 좌측 무릎 관절에 0.05ml의 4mg/ml collagenase solution을 intra-articular 주입하고, 다시 4일 후에 같은 부위에 같은 농도의 collagenase solution을 intra-articular boosting injection 시행한 뒤, gross, histopathological features 및 biomarker activity 변화를 관찰하였다. 예비실험을 통하여 CIA rat model에서 진통효과를 발휘하는 것으로 확인한, 족삼리(足三里) ($ST_{36}$)에 대한 저빈도 train pulse EA stimulation (2Hz, 0.07 mA, 0.3ms)을 침치료 방법으로 적용하였다. 전침의 진통기전을 확인하기 위하여, ${\alpha}1$-adrenergic antagonist (prazosin, 1 mg/kg, i.p.), ${\alpha}2$-adrenergic receptor antagonist (yohimbine, 2mg/kg, i.p.), ${\alpha}1$-adrenergic receptor agonist(phenylephrine, 2mg/kg, i.p.), ${\alpha}2$-adrenergic receptor agonist(clonidine, $40{\mu}g$/kg, i.p.)을 전침시행 20분 전에 복강 내로 전처치하였다. Tail flick unit(Ugo Basile Model 7360)을 이용하여 열자극에 대한 통증역치를 측정하였다. 결과 : 퇴행성관절염 징후(gross, histopathological features)와 통증역치의 변화가 최대값을 나타내는 CIA 유발 4주차에 저빈도 전침자극(train pulse, 2Hz, 0.07mA, 0.3ms)을 족삼리($ST_{36}$)에 적용하였으며, 족삼리 전침의 진통효과는 ${\alpha}2$-adrenergic receptor antagonist(yohimbine, 2mg/kg, i.p.)전처치에 의해 억제되었으나, ${\alpha}1$-adrenergic antagonist(prazosin, 1 mg/kg, i.p.)전처치에는 억제되지 않았다. 또 ${\alpha}2$-adrenergic receptor agonist(clonidine, $40{\mu}g$/kg, i.p.)의 전처치를 통하여 유의한 synergistic analgesic effect가 관찰되었으나, ${\alpha}1$-adrenergic receptor agonist(phenylephrine, 2mg/kg, i.p.)의 전처치는 전침의 진통효과에 synergistic effect를 미치지 않는 것으로 나타났다. 결론 : 저빈도 족삼리 전침은 CIA로 유발된 염증성 통증에 대하여 진통효과를 발휘하며, 이는 ${\alpha}2$-adrenergic receptor에 의하여 매개되는 것으로 보이며 ${\alpha}1$-adrenergic receptor는 영향을 미치지 않는 것으로 사료된다.

  • This experiment was designed to study possible roles of $interleukin-1\beta$, interleukin-6 and tumor necrosis $factor-\alpha$ in bone remodeling by measuring their effects on $PGE_2,\; LTB_4$ and collagenase production when they were administered to human periodontal ligament fibroblasts. Human periodontal ligament fibroblasts were collected from first premolars extracted for orthodontic treatment. They were incubated in the environment of $37^{\circ}C,\;5\%\;Co^2,\;and\;100\%$ humidity. They were treated with $0.25\%$ trypsin-EDTA solution and centrifuged. PDL cells in the fifth to seventh passage were used for the experiment. Cells were seeded onto the culture dishes and when they were successfully attached, human recombinant $interleukin-1\beta$, interleukin-6, and tumor necrosis $factor-\alpha$ were administered, alone or in combination. They were incubated for 4, 8 and 24 hours and the levels of $PGE_2,\;LTB_4$ and collagenase released into the culture media were assessed by enzymeimmunoassay and collagenase activity assay. The conclusions are as follows: 1. $IL-1\beta\;and\;TNF-\alpha$ were very active in stimulating the production of $PGE_2$ and collagenase by human periodontal ligament fibroblasts, while IL-6 increased $LTB_4$ production. 2. $IL-1\beta$ significantly increased $PGE_2$, but $LTB_4$ Production was not increased. $IL-1\beta$ is thought to act mainly via the cyclooxygenase pathway of arachidonic acid metabolism. 3. IL-6 tended to inhibit $IL-1\beta$ in the production of $PGE_2$ and collagense whereas IL-6 and $TNF-\alpha$ showed auditive effect in the level of $PGE_2$. The above cytokines increased the release of at least one of $PGE_2,\;LTB_4$ and collagenase. It suggests that cytokines are involved in bone remodeling process by stimulating PDL fibroblasts to produce various bone-resorptive agents. The roles of cytokines in bone remodeling as a whole would need further study.

  • Panax ginseng C.A. Meyer, Korean herb medicine, has been widely used in China and Japan for fatigue and enhancement of resistance to many diseases. In this study, we investigated the synergistic effect of Korean red ginseng and Fagopyrum esculentum extracts (RGFE) on dermal bioactive properties. RGFE treatment significantly increased electron donating ability, nitrite scavenging activity and collagenase inhibitory activity compared to red ginseng-treated group. Superoxide dismutase (SOD) activity in RGFE-treated group was similar to that of red ginseng. However, tyrosinase activity as indicator of melanin synthesis was not affected by RGFE or red ginseng. The results indicate that RGFE has anti-oxidative property and inhibitory effect of collagenase, and it may serve as a effective ingredient for beauty food.

  • Objectives: Bletillae Rhizoma, the roots of Bletilla striata, is used to restrain the leakage of blood and stop bleeding. It can cure the sores, ulcers, and chapped skin. This study was designed to investigate the collagen metabolism, elastase and tyrosinase activity of Bletillae Rhizoma extract (BR). Methods : The effects of BR on type I procollagen production and collagenase activity in human normal fibroblasts Hs68 after UVB (312 nm) irradiation were measured by ELISA method. The elastase activity, tyrosinase activity, and L-DOPA oxidation after treatment of BR were measured as well. Results : In the present study, the collagen production (type I procollagen) was significantly increased to $15.7{\pm}1.8$ ng/ml at a concentration of BR 100 ${\mu}g/ml$ in UVB damaged Hs68 cells. The increased collagenase activity after UVB damage was significantly recovered to $42.7{\pm}0.7%$, $54.5{\pm}3.5%$, and $38.4{\pm}0.9%$ by BR 10, 30, and 100 ${\mu}g/ml$. The activities of BR 10 mg/ml on tyrosinase activity was significantly reduced to $45.1{\pm}8.4%$ as well. However, there were no significant effects on the elastase activity and the L-DOPA oxidation. Conclusion : BR showed the promoting effects of collagen synthesis and inhibitory effects of collagenase activity in Hs68, human normal fibroblast cells. And these could be thought to have the anti-wrinkle effects and whitening effects in vitro. These results suggest that BR may have potential as an anti-aging ingredient in cosmetic treatment.

  • Sargassum micracanthum (SM) is a member of the family Sargassaceae and commonly occurs along the coast of Korea. Extracts from SM were evaluated for their antioxidant and collagenase and tyrosinase inhibitory activities based on their total phenolic concentration (TPC), 1,1-diphenyl-2-picrylhydrazyl (DPPH) radical scavenging effect, and metal-chelating effect. The TPC of SM ethanol and water extracts used in the study was 11.20 and 11.70 mg/g of dry sample, respectively. Both SM ethanol and water extracts had high DPPH radical-scavenging effect. The metal-chelating effect of SM ethanol extract (40.47% at 0.5 mg/ml) was higher than that of water extract (23.28% at 0.5 mg/ml). With regard to the anti-wrinkling effect, SM ethanol extract showed collagenase inhibitory activity with an $IC_{50}$ value of $488.20{\mu}g/ml$. Lastly, regarding the anti-melanogenesis effect, SM ethanol extract showed higher tyrosinase inhibitory activity (45.08% at 5 mg/ml) than that shown by the water extract (21.29% at 5 mg/ml). These results suggest that SM has the potential to be a resource with natural anti-melanogenesis, anti-wrinkle, and anti-oxidant effects.

  • There were many reports that elevations in the levels of active and latent collagenase in gingival crevicular fluid(GCF) have been correlated positively with periodontal disease activity. To provide a simple diagnostic approach for testing GCF collagenolytic activity, the detection limit of enzyme activity was compared using radiofibril assay(Sodek et.al.1981) and spectrophotometric collagenolytic assay(Nethery et al. 1986). The detection limits of both assay for standard bacterial enzyme were similar and the radiofibril assay showed a little (1/2) lower detection limit for tad pole collagenase. To evaluate the relationship between periodontal tissue destruction and the collagenolytic activity, GCF was collected, and latent and active enzyme activities were measured by a spectrophotometric collagenolytic assay. Twelve subjects showing progressive lesions were selected according to the presence of immediate tissue destruction, frequent abscess formation, and increasing need for tooth extraction, and the absence of underlying systemic disease and previous antibiotic medication history within 6 months. Comparisons were made between sites with either: 1) inflammation with a previous history of progressive loss of periodontal tissue and bone support(2l progressive sites): 2) previous history of bone loss and periodontal destruction but now clinically stable(12 comparably stable sites); or 3) no loss of periodontal tissue and bone support(11 control sites including 5 gingivitis sites and 6 healthy sites). Active collagenase activity was the highest in the progressive sites and decreased in the order of the gingivitis sites, the stable sites, and the healthy sites. The total enzyme activity was $2{\sim}3$ fold higher in the progressive sites and the gingivitis sites, compared to the stable and the healthy sites. The ratio of active to total collagenolytic activity was twice in the progressive sites. Analysis of active collagenase level(5mU) and the ratio of active to total collagenolytic activity(0.8) as a diagnositic test indicates that these measurements have the sensitivity of 0.81 and 0.86, the specificity of 0.70 and 0.65, and the overall agreement of 0.75 and 0.73, respectively. Thus, this method has significant merits as a diagnostic tool to determine wherher the site is in a state of remission or progression.
