  • The aim of this study was to investigate the inhibitory effect of Saengangeonbitang-gasamchilgn(SGGBTGSCG) on collagen production in rat hepatic stellate cells(HSC) and on the TAA-induced chronic liver injury model in rats. Methods : 1) HSCs were treated with SGGBTGSCG extract powder(50% EtOH SGGBTGSCG, dw SGGBTGSCG). After the treatment, MTT assay, BrdU assay and procollagen assay were done. In addition, gene expressions of collagen type $1{\alpha}2$, ASMA, TIMP1, and TIMP2, all of which are known to be associated with liver fibrosis, were analyzed by RT-PCR. 2) Liver fibrosis was developed in rats by injection of TAA 3 times a week for 5 weeks. After the SGGBTGSCG-treatment, body weight, liver & spleen weight, liver function test, the complete blood cell count and the change of portal pressure were studied. Results : In MTT assay, SGGBTGSCG significantly decreased the viability of HSCs in a dose-dependent manner. In BrdU assay, SGGBTGSCG significantly inhibited the HSC proliferation in a dose-dependant manner. In procollagen assay, SGGBTGSCG decreased procollagen production by HSC. In the change of rats' liver and spleen weight, TAA+SGGBTGSCG groups showed little difference compared with TAA-only group. In the liver function test, SGGBTGSCG decreased the serum level of ALT, AST, and Alp elevated by TAA. In the complete blood cell count, SGGBTGSCG significantly decreased WBC elevated by TAA and increased RBC and Hct lowered by TAA. In the change of portal pressure, SGGBTGSCG decreased portal pressure elevated by TAA. Conclusions : These results suggest that SGGBTGSCG is beneficial in the treatment of cirrhotic patients as well as for patients with chronic hepatitis.

  • The effects of slaughter age (28, 32, or 38 mon) on the proximate composition, collagen content, fatty acid composition, amino acid content, and mineral contents of horse leg bone (femur and tibia) extracts (HLBE) obtained from Jeju crossbred horses (n=14) in Korea. HLBE was extracted for 24 h with boiling water. At those ages, the respective proximate compositions of the HLBE were found as follows: 5.20-6.42% crude protein; fat 0.61-1.65% crude; and 0.10-0.22% crude ash. At 32 and 38 mon, the HLBE showed higher levels of both crude protein and collagen than at 28 mon. The major fatty acids of the horse leg bone extract powder (HLBP) were palmitic acid and oleic acid. Palmitoleic acid and the essential fatty acids were higher in the HLBP at 38 mon compared to that at 28 mon. Nearly all the amino acids were found at higher levels in the HLBP at 38 mon than at 28 mon, except histidine. The P, K, Zn, Se and Fe contents in the HLBP increased significantly with age. These results suggest that some nutrients in the HLBE increase with age, and that extracts from horses older than 32 mon would be more nutritious for human consumers.

  • Objective : Excessive bleeding from the exposed cancellous bone surface may cause serious problem such as hematoma formation, infection, transfusion reaction during operation and postoperative period. There are several kinds of bleeding control agent on the cancellous bone surface including bone wax, gelatin sponge ($Gelfoam^{(R)}$), oxidized cellulose($Oxycel^{(R)}$, $Surgicel^{(R)}$), thrombin, microfibrillar collagen($Avitene^{(R)}$) etc. In the past, bone wax was used to control bone bleeding but it is associated with increased infection rate and fusion failure. Recently, gelfoam paste has been used to control cancellous bone bleeding. We controlled the cancellous bone bleeding with the mixture of gelfoam powder and thrombin powder. Material and Methods : Seventeen patients of posterior fusion on the 4 motion segments of thoracolumbar spine were selected to compare the result of bone bleeding control. In the test group of 9 patients, the cancellous bone bleeding was controlled with the mixture of Gelfoam and thrombin powder during operation. In the control group of 8 cases, no chemical hemostatic agent was used to manage the bone bleeding during operation. We calculated the total amount of bleeding from cancellous bone surface during and after operation in the two groups and compared their statistic significance of the result which was judged by student t-test. Results : The average amount of intraoperative bleeding was 1825ml in control group, 811ml in test group(p<0.01). The amount of postoperative bleeding was 943ml in control group and 812ml in test group, there were no significant difference in the amount of bleeding during postoperative period between two groups(p>0.5). Total amount of blood was decreased in as much as 1150ml in test group(p<0.01). Conclusion : We concluded that the application of the mixture of thrombin and gelfoam powder on the cancellous bone surface is the effective control method of cancellous bone bleeding for multilevel posterior spinal fusion.

  • A saline suspension of Lumbricus rubellus earthworm powder (EWP) was administered to rats (1 g/kg/day) orally for 15 days to evaluate an oral effectiveness for thrombotic disorders. Blood was drawn at 2-day interval after the administration. Several parameters for antithrombotic, anticoagulant and fibrinolytic activities were measured, including platelet aggregation, clotting time, plasmin activity and the levels of FDP (fibrin/fibrinogen degradation products), D-dimer, and t-PA antigen. It did not affect platelet aggregation induced by ADP and collagen but anticoagulant activity (aPTT and TT) was gradually increased to two-folds for the first 5 days of administration and back to normal. Fibrinolytic activity of euglobulin fraction was highest on the 11 th day after the administration. The level of FDP was elevated to be comparable to the positve control$ (5-10 {\mu}g/ml)$ after 9-day treatment. Oral administration of the EWP could also reduce the formation of venous thrombus induced with viper venom. Complete blood count (CBC) profiles were within normal ranges except for a slight increase in white blood cells after the oral administration for 15 days. These results suggested that the EWP may be valuable for the prevention and/or treatment of thrombotic diseases.

  • Purpose : In this study, we intended to observe the anti-wrinkle and moisturizing effects of dried pomegranate juice concentration powder (PCP) using in vitro test. Materials and methods : Antioxidant effects of PCP were determined by free radical scavenging capacity (DPPH assay) and the cytotoxicity of PCP was examined in human keratinocyte (HaCaT) and human primary dermal fibroblast-neonatal (HDF) cells. To investigate the moisturizing effect of PCP, hyaluronan synthesis was examined in HaCaT cells. Activity of procollagen production were assessed in HDF cells and elastase inhibition properties of PCP were evaluated in cell free condition, to determine their anti-wrinkle effects. Metalloproteinase 1 (MMP-1) activity was also assessed following UVB irradiation, in the current in vitro experiment. Results : No PCP treatment related significant cytotoxic effects were demonstrated against to the both HDF and HaCaT cells. PCP showed favorable free radical scavenging activities in dose-dependent manner. In PCP-treated HaCaT cells, hyaluronan synthesis was non-significantly but markedly increased, and pro-collagen productions were significantly increased in HDF cells, at all three different concentrations (0.25, 0.75 and 1 mg/ml), and elastase inhibitory activities were observed by PCP treatment. A significant decrease in UVB-induced MMP-1 activity was also observed in 1 mg/ml PCP-treated HDF cells as compared to those of UVB-exposed cells. Conclusions : Taken together, these results suggest that PCP has favorable antioxidant, anti-wrinkle and moisturizing effects without meaningful cytotoxicity on HDF and HaCaT cell lines.

  • Introduction: Auto-tooth bone graft material consists of 55% inorganic hydroxyapatite (HA) and 45% organic substances. Inorganic HA possesses properties of bone in terms of the combining and dissociating of calcium and phosphate. The organic substances include bone morphogenetic protein and proteins which have osteoinduction capacity, as well as the type I collagen identical to that found in alveolar bone. Auto-tooth bone graft material is useful as it supports excellent bone regeneration capacity and minimizes the possibility of foreign body reaction,genetic diseases and disease transmission. Materials and Methods: Implant placement combined with osteoinductive regeneration,preservation of extraction socket, maxillary sinus augmentation, and ridge augmentation using block type,powder type, and block+powder type autobone graft materialwere performed for 250 patients with alveolar bone defect and who visited the Department of Oral and Maxillofacial Surgery, College of Dentistry, Dankook University from September 2009 to August 2011. Results: Clinical assessment: Among the 250 patients of auto-tooth bone graft, clinical assessment was performed for 133 cases of implant placement. The average initial stabilization of placed implants was 74 implant stability quotient (ISQ). Radiological assessment: The average loss of crestal bone in the mandible as measured 6 months on the average after the application of prosthesis load was 0.29 mm, ranging from 0 mm to 3.0 mm. Histological assessment: In the histological assessment, formation of new bone, densified lamellated bone, trabecular bones, osteoblast, and planting fixtures were investigated. Conclusion: Based on these results, we concluded that auto-tooth bone graft material should be researched further as a good bone graft material with osteoconduction and osteoinduction capacities to replace autogenous bone, which has many limitations.

  • Allomatrix (Wright Medical Tech, Inc., Arlington, Tenn, USA), is a newly designed, injectable putty with a reliable demineralized bone matrix (DBM), derived from human bone. The compound contains 86% DBM and other bone growth factors such as bone morphogenic protein (BMP)-2, BMP-4, insulin-like growth factor (IGF)-1, and transforming growth factor (TGF)-${\beta}1$. It has excellent osteoinduction abilities. In addition, DBM is known to have osteoconduction capacity as a scaffold due to its collagen matrix. This product contains a powder, which is a mix of DBM and surgical grade calcium sulfate as a carrier. A practitioner can blend the powder with calcium sulfate solution, making a putty-type material which has the advantages of ease of handling, better fixation, and no need for a membrane, because it can function as membrane itself. This study reports the clinical and radiographic results of various guided bone regeneration cases using Allomatrix, demonstrating its strong potential as a graft material.
