The objective of this study was to evaluate the anti-inflammation effect of extract of Carthamus tinctorious seed, on skin obtained from Gyeong buk, Korea. Regulatory mechanisms of cytokines and nitric oxide (NO) involved in immunological activity of Raw 264.7 cells. Tested cells were pretreated with 70% ethanol extracted of Carthamus tinctorious seed and further cultured for an appropriated time after the addition of lipopolyssacharide (LPS). During the entire experimental period, 5, 10, 25 and 50 ${\mu}g/ml$ of Carthamus tinctorious seed showed no cytotoxicity. In these concentrations, ethyl acetate layer of ethanol extracted Carthamus tinctorius seed (CT-E/E) inhibited the production of NO and prostaglandin $E_2$ ($PGE_2$), tumor necorsis factor-a (TNF-${\alpha}$), interleukin-$1{\beta}$ (IL-$1{\beta}$), interleukin-6 (IL-6) expression of inducible NO synthase (iNOS), cyclooxygenase-2 (COX-2). At a 50 ${\mu}g/ml$ level of CT-E/E, $PGE_2$, iNOS and COX-2 inhibition activity were shown 60%, 38%, and 42%, respectively. In addition, CT-E/E reduced the release of inflammatory cytokines including TNF-${\alpha}$, IL-$1{\beta}$ and IL-6. These results suggest that Carthamus tinctorious seed extracts may be a potential anti-inflammatory therapeutic agent due to the significant effects on inflammatory factors.

The objective of this study was to evaluate the effect of the synthetic CopA3 peptide of Copris tripartitus on skin inflammation. Regulatory mechanisms of cytokines and nitric oxide (NO) are involved in the immunological activity of RAW 264.7 cells. Tested cells were treated with different concentrations of CopA3 and further cultured for an appropriate time after lipopolyssacharide (LPS) addition. During the entire experimental period, 5, 25, 50, and 100 ${\mu}g/ml$ of CopA3 had no cytotoxicity. At these concentrations, CopA3 inhibited tumor necrosis factor-${\alpha}$ (TNF-${\alpha}$), interleukin-$1{\beta}$ (IL-$1{\beta}$), and interleukin-6 (IL-6). CopA3 also inhibited the expression of inducible NO synthase (iNOS) and cyclooxygenase-2 (COX-2). CopA3 inhibited the activity of iNOS and COX-2 by 41% and 59%, respectively, at 100 ${\mu}g/ml$. In addition, CopA3 reduced the release of inflammatory cytokines including TNF-${\alpha}$, IL-$1{\beta}$, and IL-6. These results suggest that CopA3 may have significant effects on inflammatory factors and that it may be a potential anti-inflammatory therapeutic agent.
Stereotactic Radiosurgery require high accuracy and precision of patient positioning and target localization. We evaluate the real time positioning accuracy of isocenter using optic guided patient positioning system, ExacTrac (BrainLab, Germany), during spinal radiosurgery procedure. The system is based on real time detect multiple body markers attached on the selected patient skin landmarks. And a custom designed patient positioning verification tool (PPVT) was used to check the patient alignment and correct the patient repositioning before radiosurgery. In this study, We investigate the selected 8 metastatic spinal tumor cases. All type of tumors commonly closed to thoracic spinal code. To evaluate the isocenter positioning, real time patient alignment and positioning monitoring was carried out for comparing the current 3-dimensional position of markers with those of an initial reference positions. For a selected patient case, we have check the isocenter positioning per every 20 millisecond for 45 seconds during spinal radiosurgery. In this study, real time average isocenter positioning translation were $0.07{\pm}0.17$ mm, $0.11{\pm}0.18$ mm, $0.13{\pm}0.26$ mm, and $0.20{\pm}0.37$ mm in the x (lateral), y (longitudinal), z (vertical) directions and mean spatial error, respectively. And body rotations were $0.14{\pm}0.07^{\circ}$, $0.11{\pm}0.07^{\circ}$, $0.03{\pm}0.04^{\circ}$ in longitudinal, lateral, table directions and mean body rotation $0.20{\pm}0.11^{\circ}$, respectively. In this study, the maximum mean deviation of real time isocenter positioning translation during spinal radiosurgery was acceptable accuracy clinically.

This study describes a preliminary evaluation of the anti-inflammatory activity and anti-atopic activity of Phormium tenax leaf extracts. P. tenax leaf was extracted using 70% ethanol and then fractionated sequentially with n-hexane, methylene chloride, ethyl acetate, n-butanol. In order to effectively screen for anti-inflammatory agents, we first investigated the inhibitory effects of P. tenax leaf crude extracts and solvent fractions on production of pro-inflammatory factors[nitric oxide(NO), prostaglandin $E_2(PGE_2)$, inducible nitric oxide synthase(iNOS) and cyclooxygenase-2(COX-2)] and pro-inflammatory cytokines [tumor necrosis $factor-{\alpha}(TNF-{\alpha})$, interleukin-6(IL-6) and $interleukin-1{\beta}(IL-1{\beta})$] in lipopolysaccharide(LPS)-stimulated RAW 264.7 cells. In addition, we also evaluated of their inhibitory effect on the atopic dermatitis-like inflammatory markers such as macrophage-derived chemokine(MDC) and thymus and activation-regulated chemokine(TARC) in HaCaT cells. Among the five solvent fractions of P. tenax, methylene chloride and ethyl acetate fractions inhibited production of pro-inflammatory factors and pro-inflammatory cytokines in a dose dependent manner, respectively. These fractions were also showed inhibitory activity for MDC and TARC expression levels in $IFN-{\gamma}-stimulated$ HaCaT cells, respectively. These results suggest that P. tenax have significantly effects of anti-inflammatory activity and anti-atopic activity that might be beneficial for the topical treatment of inflammatory skin disorders.
Portulaca oleracea L. (PL) has been used in traditional medicine herb for treatment of various diseases, such as diarrhea, dysentery, and skin inflammation. Previous studies have shown that the PL regulates the inflammation by inhibition of pro-inflammatory cytokines. Although PL might have improvement effects of intestinal function and bioactive effects, there are not enough studies to demonstrate. This study investigated the effects of KDC16-2 on the improvement of intestinal function and anti-inflammatory effects in vivo and in vitro. The improvement effect of intestinal function was measured fecal amount, water content and intestinal transit rate in KDC16-2 treated ICR mice. As results, compared with the control group, the KDC16-2 group showed a significant increase in wet fecal weight, dry fecal weight and fecal water content. The intestinal transit rate of KDC16-2 group was significantly increased. Based on the results, KDC16-2 is considered to have effects on improving intestinal function. The effect of anti-inflammatory demonstrated by using dextran sulfate sodium (DSS)-induced colitis mice. The mice were administered 3% DSS along with KDC16-2 (100, 300 mg/kg) for 14 days. DSS-induced colitis mice were significantly ameliorated in KDC16-2 treated group, including body weight loss, colon length shortening, tight junction protein of colon and histological colon injury. The levels of inflammatory mediators (IgG2a, IgA, C-reactive protein and Myeloperoxidase) and pro-inflammatory cytokines (tumor necrosis factor (TNF)-${\alpha}$, Interleukin (IL)-6) which are involved in inflammatory responses were increased in the DSS-treated group as compared to those in the control group, and the levels were significantly decreased in the KDC16-2 groups. In addition, we investigated the impact of KDC16-2 on lipopolysaccharide (LPS)-induced inflammatory responses in J774A.1 cells. KDC16-2 inhibited production of prostaglandin E2 (PGE2) and reactive oxygen species (ROS). These results suggested that the KDC16-2 could effectively alleviate the dysfunction of intestinal and inflammatory mediators. Thus, these KDC16-2 can be potentially used as health functional food of intestinal.
Proton therapy using the Bragg peak is one of the radiation therapies and can deliver its maximum energy to the tumor with giving least energy for normal tissue. A cross-sectional image of the human body taken with the computed tomography (CT) has been used for radiation therapy planning. The HU values change according to the tube voltage, which lead to the change in the boundary and thickness of the anatomical structure on the CT image. This study examined the changes in the Bragg peak of the brain region according to the thickness variation in the head phantom composed of several materials using the Geant4. In the phantom composed of a single material, the Bragg peak according to the type of media and the incident energy of the proton beams were calculated, and the reliability of Geant4 code was verified by the Bragg peak. The variation of the peak in the brain region was examined when each thickness of the head phantom was changed. When the thickness of the soft tissue was changed, there was no change in the peak position, and for the skin the change in the peak was small. The change of the peak position was mainly changed when the bone thickness. In particular, when the bone was changed only or the bone was changed together with other tissues, the amount of change in the peak position was the same. It is considered that measurement of the accurate bone thickness in CT images is one of the key factors in depth-dose distribution of the radiation therapy planning.
Glioblastoma is one of the highly aggressive central nervous system tumors and it is difficult to treat owing its anatomical location. Peptides are novel class of drugs which has the potential to cross the blood brain barrier and exerts its anti-tumor activity. Here, we discovered a novel peptide from abalone (Haliotis discus hannai) next generation sequencing (NGS) data and tested its anticancer effect on glioblastoma cell line SNU-489. The anticancer activity was measured using a cytotoxicity assay in a time and dose-dependent manner. A concentration and time dependent increase in the cytotoxicity was seen in cells treated with the novel peptide. The highest cytotoxicity rate of about 67% was observed in SNU-489 cells treated with 200 µM peptide for 48 hrs. However, the cytotoxic effect was not or less observed in a normal skin cell line HaCaT at similar concentration, thus, evident of peptide's cell specific anticancer activity. In addition, the gene expression level of necroptosis-related genes was analyzed by qRT-PCR to elucidate the anticancer mechanism of the novel peptide. RIPK3 expression was significantly increased by 9.6-fold in 200 µM of novel peptide treatment group, and MLKL expression level was significantly elevated by 2-fold in 100 µM treated group compared to the control group. Therefore, this study confirmed that the novel abalone-derived peptide has anticancer potency, and it causes cancer cell death through the necroptosis mechanism. Collectively, these results suggest that the novel peptide could be candidate anticancer agent for the treatment of glioblastoma in the future.

Hesperetin(HT) is a potent antioxidant flavonoid aglycone derived from hesperidin(HD). The antioxidant, anti-inflammatory, and antimicrobial activities of HT and its cyclodextrin(CD) inclusion complexes were compared in vitro. HT was prepared by enzymatic hydrolysis of HD, and HT/CD complexes were prepared using 𝛽-cyclodextrin(𝛽-CD) and hydroxypropyl-𝛽-cyclodextrin(HP-𝛽-CD) by solvent co-evaporation method. The solubility of the HT/HP-𝛽-CD inclusion complex increased 93.5-fold compared to HT, and the solubility of HT/𝛽-CD increased 22.5-fold. The HT/HP-𝛽-CD inclusion complex showed a similar effect as HT on radical scavenging activity in antioxidant assays, whereas the HT/𝛽-CD inclusion complex showed slightly lower activity than HT. Cytotoxicity was low in the following order; HT/HP-𝛽-CD, HT/𝛽-CD, and HT in murine macrophage RAW264.7 cells. Treatment with HT and HT/CD inclusion complexes reduced the levels of inflammatory mediators such as nitric oxide(NO), tumor necrosis factor-𝛼(TNF-𝛼) and interleukin-6(IL-6) in the cells. HT and HT/HP-𝛽-CD inclusion complex were more effective than HT/𝛽-CD inclusion complex at relatively low concentrations. Inhibitory effects were tested on skin-pathogenic bacteria, Staphylococcus aureus and Pseudomonas aeruginosa, and they showed an antimicrobial effect on S. aureus in the order of HT = HT/HP-𝛽-CD > HT/𝛽-CD, but they did not show any significant inhibitory effect on P. aeruginosa. In conclusion, HT, the aglycone form of HD, and its CD inclusion complexes showed various biological activities. HT/HP-𝛽-CD inclusion complex, which is the highly soluble form of HT, showed relatively higher activity compared to HT/𝛽-CD inclusion complex.

The present study was designed to investigate whether ethanol extracts of Sophora flavescens (GS), Glycyrrhiza uralensis (GC), Dictamnus dasycarpus (BSP), and their mixtures (GGB-1, -2, -3, and -4) inhibit 1-chloro-2,4-dinitrobenzene (DNCB)-induced atopic dermatitis (AD) in a mouse model. DNCB was topically applied on the dorsal surface of Balb/c mice to induce AD-like skin lesions. The pathological phenotypes of AD, such as erythema, ear thickness, edema, scabs, and discharge, were significantly decreased in the GGB (DNCB + GS:GC:BSP = 3:1:1 mixture)-1-treated groups compared with the other treated groups. The weight of the spleen in immune organs was significantly decreased in the GGB-1-treated groups, whereas the weight of the liver in a control group was similar to that of the groups treated with the samples. Furthermore, toluidine blue staining analysis, a method used to specifically identify mast cells, showed that master cell infiltration into the dermis of the GGB-1-treated group was significantly decreased. The immunoglobulin E concentration was lower in the GGB-1-treated group. In addition, the levels of inflammatory cytokines (interferon-${\gamma}$, interleukin-1, 4, 5, 6, and 13, $1{\beta}$, and tumor necrosis factor-${\alpha}$) were also significantly reduced in the GGB-1-treated group. Taken together, these results suggest that a mixture of GS, GC, and BSP in a proportion of 3:1:1 (GGB-1) may contribute to the relief of AD symptoms and may be considered an excellent candidate for an AD therapeutic drug.

This is a retrospective review of 33 patients with large cell lung carcinoma treated at Yonsei University Cancer Center between Jan.1985 and Dec.1989. Of the thirty-three patients, twenty eight were men and five women. Median age was 59 years. Large cell undifferentiated carcinoma was the most common pathologic type, $78.8\%$. Twenty one of thirty three patients had far advanced diseases, stage IIIB-IV at the time of initial diagnosis. Pleural effusion was initially presented in 12 patients, and SVC syndrome appeared in 5 patients. As to location of the primary tumor,19($57.6\%$) appeared in the right lung and 14 ($42.4\%$) in the left. Patients with a centrally located primary tumor mass were nearly the same as those peripherally located (17 vs.16). Fifteen of thirty three patients developed metastasis involving not only bone, brain, the opposite lung, adrenal gland but also soft tissue, skin, pancreas and appendix. Treatment was individualized with 19 treated radically and 14 palliatively. After treatment, only two patients showed a complete response. Long term survival was observed in 4 patients: 1 (24 mo.),2 (41 mo.) and 1 (54 mo.). The overall 2 year survival rate was $14.3\%$ while the median survival time was 6.0 months. Through the analysis of the various factors affecting survival, we observed that pleural effusion-absent group and complete response group had a statistical significant better survival rate (p<0.01).
