The aim of this study was to evaluate the effects of Welsh onion administration on $CCl_4$-induced hepatic injury in rats. The increasing rate of the body and organ weight was not significantly different by the ad-ministration of the Welsh onion. Welsh onion (2, 4, $10\%$ w/w) was given for 4 weeks with the injections of $CCl_4$. Total serum lipid was significantly decreased in all treatment groups compared to $CCl_4$ only treatment group (p<0.05). The Welsh onion from winter season was more protective effect by lowering the serum levels of transminase (SGOT and SGPT) compared with others, the levels of transminase - phosphatase (ALP) in serum. The Welsh onion from winter at a dose of $4\%,\;10\%$ (w/w) showed significantly hepatoprotective activity which was comparable to that $CCl_4$-induced hepatic damage. Histological evaluation showed that Welsh onion partially prevented $CCl_4$-induced inflammation, necrosis and vacuolation. Pretreatment of Welsh onion reduced extent of the necrosis found 24 hr after the intraperitoneal administration of $CCl_4$. The present study shows the liver protective action of the Welsh onion against experimentally induced liver damage in rats. This suggests that the Welsh onion may be used as an effective hepatoprotective agent.

In this study, the effect anti-oxidant, anti-inflammatory, and liver protective activity was investigated via quick ultrasonic disintegration of pine pollen using a probe sonicator (PS) followed by the extraction with water, 70% ethanol, and 100% ethanol. The anti-inflammatory effect was studied by measuring the production of nitric oxide (NO) and cytokine in RAW264.7 cells induced with lipopolysaccharides (LPS). The cell toxicity was also checked with an 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide (MTT) assay, and the experiment was conducted using non-toxic $100{\mu}g/mL$. The NO inhibition rate was highest in the 70% ethanol PS group at $85.99{\pm}0.12%$. Also an excellent efficiency was obtained from the results of interlukin-1 beta ($IL-1{\beta}$) and tumor necrosis factor alpha ($TNF-{\alpha}$), which is related to inflammation-related cytokine, with the respective inhibition rates of 63 and 22%. To examine liver protective activity, HepG2 cells were treated with Taclin, and the generation of glutamic oxaloacetic transaminase (GOT) and lactate dehydrogenase (LDH) was measured in the culture solution. From GOT and LDH generation results, the inhibition rates in the 70% ethanol PS group were 28% and 13%, respectively, which was higher compared to that of using negative control group. Our results suggest that pine pollen extracted in 70% ethanol using PS may be used to develop food products that have anti-aging, anti-inflammatory, and liver protective effects.

Objective : The effectiveness of gamma knife radiosurgery (GKR) in the treatment of brain metastases is well established. The aim of this study was to evaluate the efficacy and safety of maximizing the radiation dose in GKR and the factors influencing tumor control in cases of small and medium-sized brain metastases from non-small cell lung cancer (NSCLC). Methods : We analyzed 230 metastatic brain tumors less than 5 mL in volume in 146 patients with NSCLC who underwent GKR. The patients had no previous radiation therapy for brain metastases. The pathologies of the tumors were adenocarcinoma (n=207), squamous cell carcinoma (n=18), and others (n=5). The radiation doses were classified as 18, 20, 22, and 24 Gy, and based on the tumor volume, the tumors were categorized as follows : small-sized (less than 1 mL) and medium-sized (1-3 and 3-5 mL). The progression-free survival (PFS) of the individual 230 tumors and 146 brain metastases was evaluated after GKR depending on the pathology, Eastern Cooperative Oncology Group (ECOG) performance score (PS), tumor volume, radiation dose, and anti-cancer regimens. The radiotoxicity after GKR was also evaluated. Results : After GKR, the restricted mean PFS of individual 230 tumors at 24 months was 15.6 months (14.0-17.1). In small-sized tumors, as the dose of radiation increased, the tumor control rates tended to increase (p=0.072). In medium-sized tumors, there was no statistically difference in PFS with an increase of radiation dose (p=0.783). On univariate analyses, a statistically significant increase in PFS was associated with adenocarcinomas (p=0.001), tumors with ECOG PS 0 (p=0.005), small-sized tumors (p=0.003), radiation dose of 24 Gy (p=0.014), synchronous lesions (p=0.002), and targeted therapy (p=0.004). On multivariate analyses, an improved PFS was seen with targeted therapy (hazard ratio, 0.356; 95% confidence interval, 0.150-0.842; p=0.019). After GKR, the restricted mean PFS of brain at 24 months was 9.8 months (8.5-11.1) in 146 patients, and the pattern of recurrence was mostly distant within the brain (66.4%). The small and medium-sized tumors treated with GKR showed radiotoxicitiy in five out of 230 tumors (2.2%), which were controlled with medical treatment. Conclusion : The small-sized tumors were effectively controlled without symptomatic radiation necrosis as the radiation dose was increased up to 24 Gy. The medium-sized tumors showed potential for symptomatic radiation necrosis without signifcant tumor control rate, when greater than 18 Gy. GKR combined targeted therapy improved the tumor control of GKR-treated tumors.

The inflammatory response have been considered as one of important targets for cancer treatment because they play a key role during all steps of tumor development including initiation, promotion, malignant conversion and progression. To investigate the anti-inflammatory response during anti-tumor activity of an aqueous extracts of Ecklonia cava (AEC), alterations on the distribution of mast cells and the expression of inducible nitric oxide synthase (iNOS) and cyclooxygenase-2 (COX-2), nuclear factor (NF)-κB, inflammasome compositional protein and inflammatory cytokines were examined in CT26 colon tumor-bearing BALB/cKorl syngeneic mice after administrating AEC for five weeks. After treatment of AEC, total weight of tumor and necrotic region of tumor section were significantly decreased compared to vehicle treated group. The number of infiltered mast cells was higher in AEC treated group than vehicle treated group, while the expression levels of COX-2 and iNOS were decreased in AEC treated group. Also, similar decrease pattern were detected in the expression levels of NF-κB, NLR family pyrin domain containing 3 (NLRP3), apoptosis-associated speck-like protein containing a caspase recruitment domain (ASC) and caspase-1 (Cas-1) after AEC treatment although the decrease rate was varied. Furthermore, the mRNA expressions of three inflammatory cytokines including tumor necrosis factor-α (TNF-α), interleukin-1α (IL-1α) and interleukin-6 (IL-6) were remarkably decreased in AEC treated group compared to vehicle treated group. These results suggest that inhibition of inflammatory response may be tightly associated with anti-tumor activity of AEC in CT26 colon tumor-bearing BALB/cKorl syngeneic mice.
To investigate effects of Paeonia Radix Rubra aqua-acupuncture on Adjuvant Athritis in rats, the edema rate, the number of WBC, the quantity of total protein, albumin and globuline in the blood serum were measured and histological test of the muscular tissue were done in the arthritis part. 1. After arthritis of Sprague dawley(SD) rats was induced by injecting Freund's complete adjuvant for 2 weeks, normal saline was injected for the Control group and Paeonia Radix Rubra acua-acupuncture was injected for the Exp. group during 30 days. Selected point was $D{\acute{u}}bf(ST_{35})$ in both groups. And then the inframmator volume of plantar were checked. The volume of the plantar was $0.84{\pm}0.14mm$ in Control group and $0.57{\pm}0.09mm$ in Exp. group, the swelling of plantar was restricted significanily in Exp, group(P<0.05). 2. The number of WBC was $10.34{\pm}0.14(10^3/ml)$ in normal group and $37.47{\pm}5.46(10^3/ml)$ in Control group. It was $25.21{\pm}3.45(10^3/ml)$ in Exp. group. This fact showed that Exp group. with Paeonia Radix Rubra acua-acupuncture was more effective than Control group in the treatment of arthritis(P<0.05). 3. The content of total protein in the blood serum were $6.14{\pm}0.43g/d{\ell}$ in normal group, $7.95{\pm}0.94g/d{\ell}$ in Control group, and $6.82{\pm}1.23g/d{\ell}$ in Exp. group. There was no significance in total protein between Exp. group and Control group from the statistical analysis. 4. The contents of albumin in the blood serum were $2.94{\pm}0.13g/d{\ell}$ in normal group, $2.01{\pm}0.48g/d{\ell}$ in Control group and $2.75{\pm}0.14g/d{\ell}$ in Exp, group. This fact showed that Exp. group had significant increase in the serum albumin from the statistical analysis, in comparison with Control group(P<0.05). 5. The contents of globulin in the blood serum were $3.19{\pm}0.48g/d{\ell}$ in normal group, $4.70{\pm}1.26g/d{\ell}$ in Control group and $3.58{\pm}0.73g/d{\ell}$ in Exp. group. There was no significance in the serum globulin between Exp. group and Control group from the statistical analysis. 6. In histological examinadon, because inflammatory reaction was active, remarkably irregular tissue and large amount of inflammatory cells were found in Control. group. But Exp. group showed that tissues were in some degree recovered, the number of inflamed cells was decreased and inflammation was restrained. From these results, it is shown Paeonia Radix Rubra aqua-acupuncture restrained inflammatory reaction and muscular tissue necrosis in SD rat's plantar was restrained by Freund's complete adjuvant.

Purpose: Stereotactic radiosurgery (SRS) has been introduced for small-sized single and oligo-metastases in the brain. The aim of this study is to assess treatment outcome, efficacy, and prognostic variables associated with survival and intracranial recurrence. Materials and Methods: This study retrospectively reviewed 123 targets in 64 patients with non-small cell lung cancer (NSCLC) treated with SRS between January 2006 and December 2012. Treatment responses were evaluated using magnetic resonance imaging. Overall survival (OS) and intracranial progression-free survival (IPFS) were determined. Results: The median follow-up was 13.9 months. The median OS and IPFS were 14.1 and 8.9 months, respectively. Fifty-seven patients died during the follow-up period. The 5-year local control rate was achieved in 85% of 108 evaluated targets. The 1- and 2-year OS rates were 55% and 28%, respectively. On univariate analysis, primary disease control (p < 0.001), the Eastern Cooperative Oncology Group (ECOG) performance status (0-1 vs. 2; p = 0.002), recursive partitioning analysis class (1 vs. 2; p = 0.001), and age (<65 vs. ${\geq}65$ years; p = 0.036) were significant predictive factors for OS. Primary disease control (p = 0.041) and ECOG status (p = 0.017) were the significant prognostic factors for IPFS. Four patients experienced radiation necrosis. Conclusion: SRS is a safe and effective local treatment for brain metastases in patients with NSCLC. Uncontrolled primary lung disease and ECOG status were significant predictors of OS and intracranial failure. SRS might be a tailored treatment option along with careful follow-up of the intracranial and primary lung disease status.
To investigate effects of Taraxaci herbal-acupuncture on Adjuvant Arthritis in rats, the edema rate, the number of WBC, the quantity of total protein, albumin and globulin in the blood serum and histological test of the muscular tissue were measured in the arthritis part. 1. After elicitating arthritis of Sprague Dawely(SD) rats by injection of Freund's complets adjuvant for 2 weeks, saline was injected for the Exp. I group and Taraxaci herbal-acupuncture was injected for the Exp. II group during 30days. Selected point was $ST_{35}$ in both the groups. And then the volume of the paw were checked. The volume of paw was $0.84{\pm}0.14mm$ in the Exp. I group and $0.38{\pm}0.17mm$ in the Exp. II group, the swelling of the paw was restricted significantly in the Exp. II group(p<0.05) 2. The number of WBC was $10.34{\pm}0.14(10^3/ml)$ in the normal group and $37.47{\pm}5.46(10^3/ml)$ in the Exp. I group. It was $20.39{\pm}4.23(10^3/ml)$ in the Exp. II group. This fact showed that the group Exp. II was more effective than the Exp. I group in the treatment of arthritis(p<0.05) 3. The content of the total protein in the blood serum was $6.14{\pm}0.43g/dl$ in the normal group, $7.95{\pm}0.94g/dl$ in the Exp. I group, and $6.38{\pm}1.75g/dl$ in the Exp. II group. This fact showed that the group Exp. II was more effective than the Exp. I group in the treatment of arthritis(p<0.05) 4. The contents of albumin in the blood serum was $2.94{\pm}0.13g/dl$ in the normal group, $2.01{\pm}0.48g/dl$ in the Exp. I group. and $2.71{\pm}0.34g/dl$ in the Exp. II group. This fact showed that the group Exp. II was more effective than the Exp. I group in the treatment of arthritis(p<0.05) 5. The contents of globulin in the blood serum was $3.19{\pm}0.48g/dl$ in the normal group, $4.70{\pm}1.26g/dl$ in the Exp. I group. and $3.67{\pm}0.56g/dl$ in the Exp. II group. There was no significance in the serum globulin between Exp. II group and Exp. I group from the stastical analysis 6. In histological finding, because of severe inflammatory reaction, remarkably irregular tissue and large amount of inflammatory cells were found in the Exp. I group. But the Exp. II group showed small amount of inflammatory cells, the refrained inflammatory state and even recovering state. From these results, it is showed Taraxaci herbal-acupuncture refrain inflammatory reaction and muscular tissue necrosis in SD rats paw were induced by Freund's complete adjuvant

Traumatic injury of tooth in children is commonly occurred problem. It is classified into tooth, periodontal tissue, supporting bone, soft tissue injury by it's area and extent. Among the periodontal tissue injuries, traumatically intruded teeth are common in anterior maxillary area, though the occurrence rate is rather low, the pulp and supporting tissue injury is possible by vertical impact. The treatment method of traumatically intruded teeth is various. Observation on the spontaneous reeruption for 3-4 weeks is recommended if the traumatized teeth are deciduous teeth or slightly intruded immature permanent anterior teeth. If this did not occur because the extent of intrusion is severe or the traumatized teeth are mature permanent anterior teeth, orthodontic traction is applied by fixed/removable appliances. At this time, light and continuous force is applied for the extrusive movement of the intruded teeth. When above procedures are impossible, surgical repositioning and fixation is recommended. In these cases, we performed conventional endodontic therapy for pulp necrosis and orthodontic traction with fixed appliance. We obtained satisfactory results and will report that.

Laser-aided debonding has advantages in that the heat produced is localized and controlled, the debonding tool is not heated, and it can be used for the removal of various types of ceramic brackets, regardless of their design. However, the range of safe power usage for laser-aided debonding has not vet been confirmed. The Purpose of this study was to evaluate the histologic changes of pulpal tissue in a rabbit's incisor after Nd-YAG laser-aided ceramic bracket debonding at different levels of power. The result were as follows: 1. At 3-5W Nd-YAG laser power level and 3 seconds of exposure time, the ceramic bracket debonding procedure was not easy. At 5W of power a tie-wing fracture occurred on one bracket during debonding using Weingart plier. The histologic section of pulp represented no adverse changes. 2. At 7-13 W power level and less than 5 seconds of exposure time, the debracketing procedure was done easily and bracket facture did not occur. The histologic section of pulp represented mild and reversible changes. All the results were reversible and no pulpal degeneration or necrosis occurred. Considering the results, it appears that the laser-aided debonding technique is a safe method that does not result in irreversible pulpal changes, softens bracket bonding resin within a saie range of power and exposure time, and is useful for ceramic bracket recycling by lowering the tie- wing fracture rate.
Eupatorium japonicum belongs to a family of Asteraceae plants and flowers of E. japonicum have been consumed as a tea. In this study, we investigated whether E. japonicum extract inhibits lipopolysaccharide (LPS)-induced inflammatory responses in Raw264.7 macrophages. The cells were treated with various concentrations (0, 1, 2.5, 5, or 10 mg/L) of 70% ethanol extract from E. japonicum flowers (EJE) in Raw264.7 cells. LPS-induced nitric oxide (NO) and prostaglandin $E_2$ ($PGE_2$) production were inhibited by EJE up to 67% and 49% of these productions, respectively without any reduction of viable cell numbers. EJE reduced LPS-induced expression of inducible NO synthase (iNOS) and cyclooxygenase (COX)-2 proteins and their corresponding mRNA levels. Additionally, EJE decreased the levels of interleukin (IL)-6, IL-1${\beta}$, and tumor necrosis factor (TNF)-${\alpha}$ mRNA. EJE was further fractionated with water, butanol, ethylacetate (EA), hexane, or methylene chloride (MC). Among the resulting five fractions, EA and MC, respectively from EJE significantly inhibited LPS-induced NO production (each inhibition rate was 85.3% of 10 mg/L EA fraction and 97.2% of 10 mg/L MC fraction) without significant cytotoxicity in Raw264.7 cells. These results indicate that EJE exhibits powerful effects of anti-inflammation and can be developed as a potential anti-inflammatory agent.
