(R)-JG-381, a R form of alkylglycidic acid derivative, was examined for mutagenicity in the reverse mutation test on bacteria, chromosomal aberration test on cultured mammalian cells and micronucleus test in mice. In the reverse mutation test on bacteria using Salmonella typhimurium strain TA98, TA100, TA102, TA1535, TA1537 with or without a metabolic activation system (S9 mix), (R)-JG-381 did not affect the revertant colonies but significantly increased revertant colonies in one test strain, TA98, compared with the vehicle control. In the chromosomal aberration (CA) test using cultured Chinese Hamster Lung fibroblast(CHL) cells, the number of aberrant cells was clot increased in the presence or absence of 59 mix at concentration of the (R)-JG-381 0.025 $\mu$l/m1 to 0.1 $\mu$l/m1, compared with vehicle control. In the micronucleus (MN) test, micronucleated polychromatic erythrocytes in the (R)-JG-381-treated mice were not different from those of the vehicle-treated mice.

In Nan-Gyung, showed that could know the lung condition taking pulse with the weight of three beans, the heart condition taking pulse with the weight of six beans, the spleen condition taking pulse with the weight of nine beans, the liver condition taking pulse with the weight of twelve beans, the kidney condition pressing to bone(骨). This theory is first suggested in Nan-Gyung(難經). In those case, the weight of three, six, nine, twelve beans and pressing to bone don't mean not the real weight but the relative weight(輕重) of taking pulse(按脈). In other words, those represent Boo Jung Chin(浮中沈), which are the conception of the upper, the meddle, the lower part(上中下). So, we could take pulse of the heart and the lung condition in Boo(浮), the spleen condition in Jung(中), and the liver and the kidney condition in Chim(沈). The heart and the lung pulse showed in the Boo(float level) must be seen with Boo-Mack(부맥 : float pulse), the liver and the kidney pulse showed in Chim (sinklevel) must be seen also with Chin-Mack(沈脈 : sink pulse). The result of the method of taking pulse of viscera with relative weight focused on the as pect of mornal pulse(平脈) and disease pulse(病脈) of five viscera in Mack-Gyung publeshed later than Nan-Gyung and special works which made a comprehensive survey the result is as follow. 1. In normal pulse of five viscera, the heart and the lunk pulse were shown with Boo-Mack(浮脈:float pulse) as the central figure, the liver's and the kidney's pulse were shown centering around Chim-Mack(沈脈: sink pulse) and the spleen's pulse was shown with Wan-Mack(緩脈) which is vital force of stomach(胃氣) and seen in only middle part. 2. In disease pulse of five viscera, frequently, the heart and the lung pulse was shown as Chim-Mack(sink pulse), the liver and the kidney pulse was seen as Boo-Mack (float pulse). 3. In the case of normal pulse. the method of taking pulse with relative weight in Nan-Gyung agree with the normal pulse of five viscera in Mack-Gyung. But in the case of disease pulse, they didn't correspond with the other. 4. So the method of taking pulse with relative weight in Nan-Gyung is not the exam pulse which ca be used in the clinical diagnosis but one of the feeling pulse way to bring in the conception of location of the visceras. 5. From now on, the method of taking pulse rdlated to relative weight need to be looked into minutely compared with later physician's theory than Mack-Gyung.

Background: The advantages of Rapid Arc plans versus Intensity modulated radiotherapy plans for Carcinoma left breast were analyzed. Materials and Methods: In this study 20 Post mastectomy carcinoma left breast patients were analyzed. Both Intensity modulated Radiotherapy and Rapid Arc plans were generated for these patients. IMRT plans with 7 beams in an arc fashion and VMAT plans with two semi arcs were made to achieve 95% dose coverage to 100% volume. The plans were evaluated using Dose volume Histograms. Results: The mean Conformity and Homogeneity index in VMAT is found to be 1.05 and 0.065 respectively whereas in IMRT it was 1.07 and 0.069. The 20% volume of Heart received a mean dose of 960cGy in VMAT and 1300cGy in IMRT. The mean dose was 1236cGy in VMAT and 1870cGy in IMRT. The ipsilateral Lung received 3395cGy to 5% volume and 1840cGy to 20% volume on an average and the mean dose was 1205cGy in VMAT, while the same were found to be 3525cGy, 2012cGy and 1435cGy respectively in IMRT. The Contralateral Lung received a mean dose of 505cGy in VMAT and 553cGy in IMRT. The mean Monitor units in VMAT were 512MU and 1170MU in IMRT. The NTID in VMAT is $108.8{\times}10^5Gycm^3$ and $110.1{\times}10^5Gycm^3$ in IMRT. Conclusions: The target coverage, homogeneity and Conformity index were better in VMAT plans. The Ipsilateral Lung and heart dose were very less in VMAT plans. The Contralateral Lung dose and the Normal Tissue Integral Dose were also lesser in VMAT plans however the difference is not very appreciable. The MU in VMAT plans is almost 50% that of the IMRT plans which results in the reduction of treatment time. On the whole VMAT proves to be a better modality for treating Ca. Left Breast Patients.

Objective: To investigate the feasibility and the accuracy of the coronary CT angiography (CCTA)-derived Registry of Crossboss and Hybrid procedures in France, the Netherlands, Belgium and United Kingdom (RECHARGE) score (RECHARGECCTA) for the prediction of procedural success and 30-minutes guidewire crossing in percutaneous coronary intervention (PCI) for chronic total occlusion (CTO). Materials and Methods: One hundred and twenty-four consecutive patients (mean age, 54 years; 79% male) with 131 CTO lesions who underwent CCTA before catheter angiography (CA) with CTO-PCI were retrospectively enrolled in this study. The RECHARGECCTA scores were calculated and compared with RECHARGECA and other CTA-based prediction scores, including Multicenter CTO Registry of Japan (J-CTO), CT Registry of CTO Revascularisation (CT-RECTOR), and Korean Multicenter CTO CT Registry (KCCT) scores. Results: The procedural success rate of the CTO-PCI procedures was 72%, and 61% of cases achieved the 30-minutes wire crossing. No significant difference was observed between the RECHARGECCTA score and the RECHARGECA score for procedural success (median 2 vs. median 2, p = 0.084). However, the RECHARGECCTA score was higher than the RECHARGECA score for the 30-minutes wire crossing (median 2 vs. median 1.5, p = 0.001). The areas under the curve (AUCs) of the RECHARGECCTA and RECHARGECA scores for predicting procedural success showed no statistical significance (0.718 vs. 0.757, p = 0.655). The sensitivity, specificity, positive predictive value, and the negative predictive value of the RECHARGECCTA scores of ≤ 2 for predictive procedural success were 78%, 60%, 43%, and 87%, respectively. The RECHARGECCTA score showed a discriminative performance that was comparable to those of the other CTA-based prediction scores (AUC = 0.718 vs. 0.665-0.717, all p > 0.05). Conclusion: The non-invasive RECHARGECCTA score performs better than the invasive determination for the prediction of the 30-minutes wire crossing of CTO-PCI. However, the RECHARGECCTA score may not replace other CTA-based prediction scores for predicting CTO-PCI success.

Acuros XB advanced dose calculation algorithm (AXB, Varian Medical Systems, Palo Alto, CA) has been released recently and provided the advantages of speed and accuracy for dose calculation. For clinical use, it is important to investigate the dosimetric performance of AXB compared to the calculation algorithm of the previous version, Anisotropic Analytical Algorithm (AAA, Varian Medical Systems, Palo Alto, CA). Ten volumetric modulated arc therapy (VMAT) plans for each of the following cases were included: head and neck (H&N), prostate, spine, and lung. The spine and lung cases were treated with stereotactic body radiation therapy (SBRT) technique. For all cases, the dose distributions were calculated using AAA and two dose reporting modes in AXB (dose-to-water, $AXB_w$, and dose-to-medium, $AXB_m$) with same plan parameters. For dosimetric evaluation, the dose-volumetric parameters were calculated for each planning target volume (PTV) and interested normal organs. The differences between AAA and AXB were statistically calculated with paired t-test. As a general trend, $AXB_w$ and $AXB_m$ showed dose underestimation as compared with AAA, which did not exceed within -3.5% and -4.5%, respectively. The maximum dose of PTV calculated by $AXB_w$ and $AXB_m$ was tended to be overestimated with the relative dose difference ranged from 1.6% to 4.6% for all cases. The absolute mean values of the relative dose differences were $1.1{\pm}1.2%$ and $2.0{\pm}1.2%$ when comparing between AAA and $AXB_w$, and AAA and $AXB_m$, respectively. For almost dose-volumetric parameters of PTV, the relative dose differences are statistically significant while there are no statistical significance for normal tissues. Both $AXB_w$ and $AXB_m$ was tended to underestimate dose for PTV and normal tissues compared to AAA. For analyzing two dose reporting modes in AXB, the dose distribution calculated by $AXB_w$ was similar to those of AAA when comparing the dose distributions between AAA and $AXB_m$.

Objective : The purpose of this study is to report and observe effects of Traditional Korean Medicine (TKM) on stage IV metastatic breast cancer patient. Method : A right breast cancer patient diagnosed with metastatic lesions on liver, lung, spleen, multiple bones and skin on right breast April 2013. The patient received Herceptin + Docetaxel + Zometa from May 2013 and started to receive TKM since July 2013 to decrease side effects of chemotherapy. From December 2013 to November 2014, she had received Herceptin 18 times more. The clinical outcomes were measured by computed tomography, laboratory findings including tumor markers (CEA, CA15-3), liver function test (AST, ALT), and numeric rating scales (NRS). Results : After 6 years of TKM treatment combined with standard chemotherapy, tumor size was partially decreased in lung, liver, right pleura and spleen. Levels of tumor markers also showed decrease. There were no severe adverse events induced by TKM based on National Cancer Institute Common Terminology Criteria for Adverse Event (NCI-CTCAE) version 4.0. Conclusion : This case suggests that TKM combined with standard chemotherapy could be a promising method for treating metastatic stage IV breast cancer.

This study was conducted to gather the basic data on the spread of the domestic kiwifruits, and the development of the manufactured goods and the health functional foods produced using kiwifruits. We determined the chemical compositions of four types of kiwifruits cultivated in Korea, Daeheung, Bidan, Haegeum and Hayward. In addition, we measured the anti-microbial activities and cytotoxicities of these types of kiwifruits. The vitamin C contents of the kiwifruits increased in the order of Bidan (93.82 mg/100 g), Daeheung (85.89 mg/100 g), Haegeum (83.73 mg/100 g) and Hayward (75.28 mg/100 g). The total amino acids contents per 100 g of kiwifruit (dry weight basis) were 483.97 mg (Haegeum), 453.08 mg (Hayward), 437.27 mg (Bidan) and 369.35 mg (Daeheung). The K and Ca contents of the kiwifruits ranged from 14.56~37.12 mg/L and 1.94~8.24 mg/L, respectively; however, the Fe, Mg, Zn and Cr contents all less than 1.83 mg/L. The antimicrobial activities of methanol extracts of kiwifruits against five gram positive bacteria at concentration of 2,000 mg/L in terms of inhibition diameter ranged from 8.8~12.8mm, while raged from 9.2~13.1mm against three gram negative strains of bacteria. The hyperplasia inhibition of lung cancer cells (Calus-6) by 800 mg/L kiwifruits extracts of Bidan, Haegeum, Daeheung and Hayward kiwifruits were 21.2%, 9.5%, 6.7% and 5.0%, respectively. Consequently, it was assumed that kiwifruits was rich in vitamin C, amino acids and K, and that they would therefore be useful in processed goods.

Platelets from a patient with a mild inherited bleeding disorder and abnormal platelet aggregation and secretion show reduced generation of inositol 1,4,5-trisphosphate (IP$_3$), mobilization of intracellular Ca$\^$2+/, and phosphorylation of pleckstrin in response to several G protein mediated agonists, suggesting a possible defect at the level of phospholipase C (PLC) activation. A procedure was developed that allows quantitation of platelet PLC isozymes. After fractionation of platelet extracts by high-performance liquid chromatography, seven, out often known PLC isoforms were detected by immunoblot analysis. The amount of these isoforms in normal platelets decreased in the order PLC-${\gamma}$2 > PLC-${\beta}$2 > PLC-${\beta}$3 > PLC-${\beta}$l > PLC-${\gamma}$ > PLC-$\delta$1 > PLC-${\beta}$4. Compared with normal platelets, platelets from the patient contained approximately one-third the amount of PLC-${\beta}$2, whereas PLC-${\beta}$4 was increased threefold. These results suggest that the impaired platelet function in the patient in response to multiple G protein mediated agonists is attributable to a deficiency of PLC-${\beta}$2. They document for the first time a specific PLC isozyme deficiency in human platelets and provide an unique opportunity to understand the role of different PLC isozymes in normal platelet function.

Introduction: Non-small cell lung cancer (NSCLC) patients are particularly vulnerable to the Coronavirus Disease-2019 (COVID-19). Currently, no anti-NSCLC/COVID-19 treatment options are available. As ginsenoside Rg3 is beneficial to NSCLC patients and has been identified as an entry inhibitor of the virus, this study aims to explore underlying pharmacological mechanisms of ginsenoside Rg3 for the treatment of NSCLC patients with COVID-19. Methods: Based on a large-scale data mining and systemic biological analysis, this study investigated target genes, biological processes, pharmacological mechanisms, and underlying immune implications of ginsenoside Rg3 for NSCLC patients with COVID-19. Results: An important gene set containing 26 target genes was built. Target genes with significant prognostic value were identified, including baculoviral IAP repeat containing 5 (BIRC5), carbonic anhydrase 9 (CA9), endothelin receptor type B (EDNRB), glucagon receptor (GCGR), interleukin 2 (IL2), peptidyl arginine deiminase 4 (PADI4), and solute carrier organic anion transporter family member 1B1 (SLCO1B1). The expression of target genes was significantly correlated with the infiltration level of macrophages, eosinophils, natural killer cells, and T lymphocytes. Ginsenoside Rg3 may benefit NSCLC patients with COVID-19 by regulating signaling pathways primarily involved in anti-inflammation, immunomodulation, cell cycle, cell fate, carcinogenesis, and hemodynamics. Conclusions: This study provided a comprehensive strategy for drug discovery in NSCLC and COVID-19 based on systemic biology approaches. Ginsenoside Rg3 may be a prospective drug for NSCLC patients with COVID-19. Future studies are needed to determine the value of ginsenoside Rg3 for NSCLC patients with COVID-19.

Purpose: Pneumoconiosis is a chronic lung disease in which the lungs become hardened due to the accumulation of fine mineral dust that has been breathed in at industrial sites. The lungs are unable to function properly, resulting in complications of several respiratory diseases. Methods: The subjects were 36 elderly adults (pneumoconiosis patients 18, healthy elderly 18) over the age of 65 years. The respiratory function was assessed using a spirometer to measure forced vital capacity (FVC), first second of forced expiration (FEV1), FEV1/FVC, and peak expiratory flow n(PEF). The static balance function test was determined by the center of mass (COM), ankle angle range, hip angle range, sway parameters, and reciprocal compensatory index (RCI). Cognitive function was measured by applying MoCA-k. Results: Comparison of respiration functions between the two groups showed statistically significant differences in FVC, FEV1, FEV1/FVC, and PEFs (p<0.05). Cognitive abilities showed statistically significant differences due to higher cognitive skills in the control group as compared to the patient group (p<0.05). Most results of the static balance capability measurements showed statistically significant differences between the groups (p<0.05). However, no statistically significant differences were obtained for COM AP Range, Angle AP Range, RCI ML Range, and AP Range (p>0.05). Conclusion: The results of the current study indicate that patients suffering from pneumoconiosis have less cognitive ability and balance function as compared to healthy elderly people. Therefore, we expect an improvement in the balance ability and cognitive function through systematic management and strengthening lung function training to improve the quality of life of pneumoconiosis patients.
