  • This study was undertaken to purify the anticoagulant polysaccharide from Pachymeniopsis elliptica. The anticoagulant compound (PE-2IVc-2-1) was isolated from the crude polysaccharide (PE-2) by the sequential steps such as ultrafiltration (PE-2IV), anion-exchange chromatography of DEAE-Toyopearl 650C(PE-2IVc), size-exclusion chromatography of Sepharose CL-6B (PE-2IVc), and HPLC Shodex OHpak column chromatography (PE-2IVc-2-1). The apparent molecular weight of purified polysaccharide (PE-2IVc-2-1) was approximately 710 kDa. It was mainly composed of galactose (48.6%) and 3,6-anhydrogalactose (44.0%) with 27.1% of sulfate residue, in addition a trace amount of xylose (3.6%), glucose (1.1%), mannose (1.1%), arabinose (0.8%) and fucose (0.8%). The IR spectrum of the polysaccharide showed the characteristic bands of S=O(1116.74 and 1143.17 $cm^{-1}$) and C-O-S (828.19 $cm^{-1}$) stretching, respectively. The anticoagulant effect of PE-2 in ex vivo was proportional to the concentration of intravenously injected dose, up to 100 mg/kg.

  • This article is written on the ground that one of the major characteristics of Chinese New Period women's novels is about family dissolution and calling and it is examined based on analysis of "The Bathing Woman" by Tie Ning. In "The Bathing Woman", the family seems 'Regular' externally but it is actually fragmented internally. The author offers patriarchal perspective on 'Family' from the eyes of daughter of the family. The problems are classified into three categories. First, it is the problem of exclusiveness embedded in the essential characteristic of family represented by blood relation. Second, it is the research on the reason for family dissolution. Tie Ning finds the reason at 'Unmotherly mother, that is the lack of maternal instinct. Third, it is the expectation of the restoration of dissolved family. Tie Ning's indication of 'Family' is equal to 'Mother' and 'Mother' is the source and power that can heal and restore the dissolved family in her novel. It is expansion of maternal instinct represented by protection and caring into 'Practical action' and it is meaningful in a way that it expands the principle of maternal instinct and sublimates it into universal morality. However, it should not be overlooked that it could be another moral system that could suppress the females in other ways.

  • Moyamoya disease (MMD) is a progressive cerebrovascular disease with unknown etiology, characterized by bilateral steno-occlusive changes at the terminal portion of the internal carotid artery and an abnormal vascular network formation at the base of the brain. MMD has an intrinsic nature to convert the vascular supply for the brain from internal carotid (IC) system to the external carotid (EC) system, as indicated by Suzuki's angiographic staging. Insufficiency of this 'IC-EC conversion system' could result not only in cerebral ischemia, but also in intracranial hemorrhage from inadequate collateral anastomosis, both of which represent the clinical manifestation of MMD. Surgical revascularization prevents cerebral ischemic attack by improving cerebral blood flow, and recent evidence further suggests that extracranial-intracranial bypass could powerfully reduce the risk of re-bleeding in MMD patients with posterior hemorrhage, who were known to have extremely high re-bleeding risk. Although the exact mechanism underlying the hemorrhagic presentation in MMD is undetermined, most recent angiographic analysis revealed the characteristic angio-architecture related to high re-bleeding risk, such as the extension and dilatation of choroidal collaterals and posterior cerebral artery involvement. We sought to update the current management strategy for hemorrhagic MMD, including the outcome of surgical revascularization for hemorrhagic MMD in our institute. Further investigations will clarify the optimal surgical strategy to prevent hemorrhagic manifestation in patients with MMD.

  • Thrombophilia refers to inherited or acquired hemostatic disorders that result in a predisposition to blood clot formation. When combined with the hypercoagulable state that is characteristic of pregnancy, there is an increased risk of severe and recurrent pregnancy complications. Activated protein C resistance caused by factor V Leiden (FVL) mutation is known to be the most common cause of inherited thrombophilia in Caucasian population. FVL mutation has been related to pregnancy complications associated with hypercoagulation, e.g. miscarriage, intrauterine fetal demise, placental abruption, and intrauterine growth retardation. Although the FVL mutation is easily detected using molecular DNA techniques, patients who are heterozygous for this disorder often remain asymptomatic until they develop a concurrent prothrombotic condition. Because there are potentially serious effects of FVL mutation for pregnancy, and because effective treatment strategies exist, early detection and treatment of this condition might be considered.

  • In this study, obese adults were compared for their ability to predict obesity and lipid related variables and their optimal cutoff values to predict metabolic syndrome and insulin resistance. In this study, 9,256 adults aged 20 years or older and less than 80 years old, who were in the Gyeonggi region from January 2014 to December 2016 and who were examined at a general hospital, were enrolled. The diagnostic criteria for obesity were WHO (World Health Organization), and BMI $25kg/m^2$ or more presented in the Asia-Pacific region. Metabolic syndrome was diagnosed based on the criteria of American Heart Association / National Heart, Lung, and Blood Institute (AHA / NHLBI). According to the results of receiver operating characteristic curve (ROC) analysis, Triglyceride / HDL-cholesterol (TG / HDL-C), Triglyceride and Glucose (TyG) index, lipid accumulation product (LAP) and visceral adiposity index (VAI) showed high predictive power for diagnosing metabolic syndrome. The diagnostic accuracy of LAP (AUC: 0.854) for males and VAI (0.888) for females was the highest. The optimal cutoff value of LAP was 42.71 for male and 35.44 for female, and the cutoff value of VAI was 1.92 for male and 2.15 for female. In addition, WHtR (waist to height ratio), TyG index, and LAP were used as predictors of insulin resistance in obese adults. Therefore, LAP and VAI were superior to other indicators in predicting metabolic syndrome in obese adults.

  • Ginger roots are widely used as spices in various foods and herbal medicine due to its characteristic flavor and biological activity. In this study, the protective effect of aged ginger extracts against oxidative stress were investigated using L6 muscle cells. As the results, aged ginger extracts significantly inhibited oxidative stress induced muscle cell damage. The protective effect of aged ginger extracts was higher than non-aged ginger extract. Aged ginger extracts also inhibited the increase in LDH, lactate and GOT in the mouse blood induced by excessive running exercise. Therefore, aged ginger is considered to be effective for protecting excessive exercise stress.

  • In this study, a horticultural therapy program was performed by employing the anger experienced by people during daily life activities in the emotion regulation strategy-based program to identify the influence of the horticultural program on anger control in the caregivers for patients with dementia. To measure this influence, two tools were used: a self-administered questionnaire survey, which is a subjective test, and an instrumental test, which can measure the physical index that detects the physical changes through anger. For the preliminary test, depression, stress, self-esteem, anxiety, and anger state-characteristic were tested using the self-administered questionnaire. For the follow-up test, the self-administered survey and the test using the physical index were performed in a manner similar to that of the preliminary test. The self-administered questionnaire comprised questions suitable to this study and considered the age, education level, and economic aspect of the subjects. The test results indicated that the experimental group subjected to the emotion regulation strategy-based horticultural therapy showed very significant reduction in depression and anger and significant reduction in stress, self-esteem, and anxiety. In the physical index test, the systolic and diastolic blood pressures were reduced, and the pulse rate and respiration rate reduced before and after the therapy, thus, proving the effectiveness of the therapy in anger control.

  • Albizia julibrissin Durazz. (AJ; family Minosaceae) is widely distributed worldwide, and its stem bark has been used as a traditional herbal medicine. Acute kidney injury (AKI) is a clinical syndrome that results in sudden loss of renal function. This study aimed to investigate the effects of AJ against cisplatin-induced AKI using a human kidney proximal tubule epithelial cell line (HK-2) and cisplatin-treated mice. In vitro, cisplatin treatment increased apoptosis in HK-2 cells. However, AJ treatment decreased apoptosis of cisplatin-treated HK-2 cells. In vivo, cisplatin treatment accelerated renal injury by increasing the levels of renal injury markers, such as blood urea nitrogen, creatinine, kidney injury molecule 1, and neutrophil gelatinase-associated lipocalin, which were reversed by AJ treatment. Histopathologically, AJ treatment resulted in decreased renal damage with less tubular necrosis and brush border desquamation compared with the AKI group. Additionally, cisplatin treatment upregulated mitochondrial fission, a pathological characteristic of AKI, which was downregulated by AJ treatment. Along with increased mitochondrial fission, AJ treatment also reduced cisplatin-induced apoptosis. These results suggest that AJ may be a potential therapeutic agent for cisplatin-induced AKI.

  • Objectives : This study aims to examine the efficacy and application of Cannabis according to its parts. Methods : Contents on efficacy, treatment, and application of Cannabis in Material Medica and other texts of East Asian Medicine were collected and interpreted to deduce each characteristic. Results : Cannabis was found to be applicable to various wind symptoms and wind stroke, various pain and injuries, skin diseases, blockage or leaking of urine or feces, disease related to genitalia and anus, chronic ague, women's disease related to menstruation, birth, pregnancy, and to have the effects of heightening perceptive and sensory organs, detoxification and anesthesia, stimulating hair growth, and eradicating parasites. It drives out wind-heat pathogenic qi, circulates qi and blood, which allowed it to be applied not only to blockages but to symptoms of leakage. In other words, Cannabis was used when both excess and deficiency diseases were present, the former caused by acute blockage and the latter accompanied by stagnation. Conclusions : Based on the findings of this study, future researches on the efficacy and application of Cannabis could be done more systematically. In line with recent trend of wide application of medical Cannabis, we hope for it to be more actively used in the field of East Asian Medicine based on objective evidence.

  • A 12-year-old female small-clawed Asian otter (Anoyx cinereus) with a one-week history of anorexia, chills, and abdominal distension was found dead. Grossly, yellowish-brown turbid fluids accumulated in abdominal cavity of the otter, and yellowish thread-like fibrinous materials were found on the surface of abdominal organs. Several variable sized yellowish-white crystalloids were scattered on the medullary space of kidneys. Histologically, diffuse serositis (peritonitis) characterized by the fibrinous exudates, thickened serosal capsule and the swelling of mesothelial cells were observed in the serosa of liver, spleen, stomach, and intestine. Multifocal necrosis, hemorrhage, infiltration of macrophage, and brown pigments were presented in the liver. Isolated bacteria from ascites and fibrinous materials in abdominal visceral surface were white, smooth and convex with characteristic mousy odor on blood agar plate. These bacteria were confirmed as Pasteurella (P.) multocida type A by polymerase chain reaction analysis. Based on the gross examination, histopathologic findings and bacterial experiments, this otter was diagnosed as severe peritonitis associated with P. multocida and necrotic hepatitis.
