  • Objectives: The purpose of this study is to confirm the effectiveness and safety of herbal medicine treatment for treating pregnancy-induced hypertension. Methods: We searched for randomized controlled trials of pregnancy-induced hypertension treated with herbal medicine, through nine databases. Interventions and results of the selected clinical studies were analyzed. Results: Eleven randomized controlled trials were finally included according to the inclusion and exclusion criteria. Treatment group was treated with herbal medicine alone in two studies, and with herbal medicine and western medicine in nine studies. Control group was treated with western medicine. Taxilli Ramulus (桑寄生) (54.5%) was the most frequently used herb in herbal medicine treatment. In all of eleven studies, treatment group was more effective for pregnancy-induced hypertension than the control group. Conclusions: This study suggested that herbal medicine treatment alone or combined with western medicine treatment could be helpful in improving the therapeutic effect on pregnancy-induced hypertension and reducing side effects as well. However, in order to obtain stronger evidence of herbal medicine treatment for pregnancy-induced hypertension, more high-quality and well-designed randomized controlled trials should be conducted.

  • Chios gum mastic (CGM) is produced from Pistiacia lentiscus L var chia, which grows only on Chios Island in Greece. CGM is a kind of resin extracted from the stem and leaves, has been used for many centuries in many Mediterranean countries as a dietary supplement and folk medicine for stomach and duodenal ulcers. CGM is known to induce cell cycle arrest and apoptosis in some cancer cells. This study was undertaken to investigate the alteration of the cell cycle and induction of apoptosis following CGM treatment of HL-60 cells. The viability of the HL-60 cells was assessed using the MTT assay. Hoechst staining and DNA electrophoresis were employed to detect HL-60 cells undergoing apoptosis. Western blotting, immunocytochemistry, confocal microscopy, FACScan flow cytometry, MMP activity and proteasome activity analyses were also employed. CGM treatment of HL-60 cells was found to result in a dose- and time-dependent decrease in cell viability and apoptotic cell death. Tested HL-60 cells showed a variety of apoptotic manifestations and induced the downregulation of G1 cell cycle-related proteins. Taken collectively, our present findings demonstrate that CGM strongly induces G1 cell cycle arrest via the modulation of cell cycle-related proteins, and also apoptosis via proteasome, mitochondrial and caspase cascades in HL-60 cells. Hence, we provide evidence that a natural product, CGM could be considered as a novel therapeutic for human leukemia.

  • Based on advances in biotechnology and neuroscience, neuromodulation is poised to gain clinical importance as a treatment modality for psychiatric disorders. In addition to old-established electroconvulsive therapy (ECT), clinicians are expected to understand newer forms of neurostimulation, such as deep brain stimulation (DBS), vagus nerve stimulation (VNS), repetitive transcranial magnetic stimulation (rTMS), transcranial direct current stimulation (tDCS) and transcranial alternating current stimulation (tACS). Given the growing interest in non-invasive neuromodulation technologies, clinicians may seek sufficient information about neuromodulation to inform their clinical practice. A growing literature suggests that applications of non-invasive neuromodulation have evidence particularly for indications where treatments are currently insufficient, such as drug-resistant depression. However, positive neuromodulation studies require replication, and the precise interactions among stimulation, antidepressant medication, and psychotherapy are unknown. Further studies of long-term safety and the impact on the developing brain are needed. Non-invasive neuromodulatory devices could enable more individualized treatment. However, do-it-yourself (DIY) stimulation kits require a better understanding of the effects of more frequent patterns of stimulation and raise concerns about clinical supervision, regulation, and reimbursement. Wide spread enthusiasm for therapeutic potential of neuromodulation in clinical practice settings should be mitigated by the fact that there are still research gaps and challenges associated with non-invasive neuromodulatory devices.

  • 혈관신생은 모든 조직의 성장과 발달, 그리고 상처회복 등에 매우 중요하다. 지방조직은 우리 몸에서 가장 혈관이 발달된 조직으로서 각 지방세포들은 모세혈관에 둘러싸여 있으며 신생혈관들은 지방세포에 영양분과 산소를 공급한다. 혈관의 내피세포들은 파라크린 신호경로, 세포외 성분, 세포들 간의 직접적인 작용을 통해 지방세포와 교류한다. 활성화된 지방세포들은 VEGF, FGF-2, leptin, HGF와 같은 혈관신생인자들을 생성하며, 이들은 단독으로 혹은 협력하여 혈관신생을 증가시키고 지방조직의 성장과 대사를 촉진한다. 따라서 혈관신생 억제제들은 비만과 비만관련 질환을 치료하는데 유용할 것으로 생각된다.

  • Traditionally, the root of Lithospermum erythrorhizon Sieb. et Zucc(L.E) has been used as efficacious therapy for inflammation, burns, frostbite and skin ailments (e.g eczema and psoriasis). It contains isohexenylnaphthoquinone derivatives (shikonin and its esters) and furylhydroquinones (shikonofurans) in lipophilic fractions and caffeic acid oligomers (rosmarinic acid, lithospermic acid B) in polar fractions. Recently, new preparative isolation and analysis procedures of shikonin along with its oligomers from the extract of L. erythrorhizon by the combination of high-speed counter-current chromatography with high-performance liquid chromatography-diode array detection have also been introduced. Although there have been many reports on the wound healing, antiinflammatory, and anticancer effects, the research on the effects of anti-atopic dermatitis of the root of L. erythrorhizon were relatively scarce. However, in recent years, new information gathered from research efforts, on the anti-atopic dermatitis properties of the extract or constituents of L. erythrorhizon has been accumulated. In this paper, the findings and advance on the in vitro and in vivo activities of L. erythrorhizon and its constituents especially focused on antiinflammatory and anti-atopic dermatitis effects are summarized. The phytochemical constituents of L. erythrorhizon or its tissue cultures are also presented. Although there are few to verify or refute its activity in human, one result of clinical study of the extract of L. erythrorhizon on the atopic dermatitis patients was introduced to assess the possibility of its clinical use. The reported mechanisms of action and in vivo pharmacological studies in different animal models for the various types of extracts or constituents of L. erythrorhizon are supportive of its therapeutic potential or dietary supplement, however, more evidence from clinically relevant models, as well as systemic studies on the active constituents or the various types of standardized extracts at the cellular and molecular level, are required.

  • Oroxylum indicum has long been used in Asian traditional medicine to prevent and treat respiratory diseases, diabetes, diarrhea and other conditions. Oroxylin A is a flavone that is present in Oroxylum indicum and in Scutellaria baicalensis. Because the root extracts of both plants have been shown to have anti-allergic effects, the authors investigated whether oroxylin A is likely to have beneficial effects on allergic asthma using female Balb/c mice and rat RBL-2H3 mast cells. Antigen-induced degranulation was measured in vitro by measuring b-hexosaminidase activity. A murine ovalbumin-induced allergic asthma model was used to test the in vivo efficacy of oroxylin A. Sensitization and challenge of ovalbumin induced allergic asthma responses, the accumulations of eosinophils and Th2 cytokine levels in bronchoalveolar lavage fluid and lung tissues. Oroxylin A administration decreased numbers of inflammatory cells, especially eosinophils, and reduced the expression and secretion of Th2 cytokines, including IL-4 and IL-13, in lung tissues and bronchoalveolar lavage fluid. Histologic studies showed oroxylin A reduced inflammatory signs and mucin production in lungs. These findings provide evidence that oroxylin A has potential use as an anti-allergic therapeutic.

  • Cyperi Rhizoma (CR), the rhizome of Cyperus rotundus L., exhibits neuroprotective effects in in vitro and in vivo models of neuronal diseases. Nevertheless, no study has aimed at finding the neuroactive constituent(s) of CR. In this study, we identified active compounds in a CR extract (CRE) using bioactivity-guided fractionation. We first compared the anti-oxidative and neuroprotective activities of four fractions and the CRE total extract. Only the ethyl acetate (EA) fraction revealed strong activity, and further isolation from the bioactive EA fraction yielded nine constituents: scirpusin A (1), scirpusin B (2), luteolin (3), 6'-acetyl-3,6-diferuloylsucrose (4), 4',6' diacetyl-3,6-diferuloylsucrose (5), p-coumaric acid (6), ferulic acid (7), pinellic acid (8), and fulgidic acid (9). The activities of constituents 1-9 were assessed in terms of anti-oxidative, neuroprotective, anti-inflammatory, and anti-amyloid-${\beta}$ activities. Constituents 1, 2, and 3 exhibited strong activities; constituents 1 and 2 were characterized for the first time in this study. These results provide evidence for the value of CRE as a source of multi-functional neuroprotectants, and constituents 1 and 2 may represent new candidates for further development in therapeutic use against neurodegenerative diseases.

  • ZAS3 is a large zinc finger transcription repressor that binds the ${\kappa}B$-motif via two signature domains of ZASN and ZASC. A loss-of-function study showed that lack of ZAS3 protein induced accelerated cell proliferation and tumorigenesis. Conversely, gain-of-function studies showed that ZAS3 repressed $NF{\kappa}B$-activated transcription by competing with $NF{\kappa}B$ for the ${\kappa}B$-motif. Based on these observations, we hypothesize that ZAS3 promotes apoptosis by interrupting anti-apoptotic activity of $NF{\kappa}B$. Here, we present evidence that upon $TNF{\alpha}$ stimulation, ZAS3 inhibits $NF{\kappa}B$-mediated cell survival and promotes caspase-mediated apoptosis. The inhibitory effect of ZAS3 on $NF{\kappa}B$ activity is mediated by neither direct association with $NF{\kappa}B$ nor disrupting nuclear localization of $NF{\kappa}B$. Instead, ZAS3 repressed the expression of two key anti-apoptotic genes of $NF{\kappa}B$, TRAF1 and TRAF2, thereby sensitizing cells to $TNF{\alpha}$-induced cell death. Taken together, our data suggest that ZAS3 is a tumor suppressor gene and therefore serves as a novel therapeutic target for developing anti-cancer drugs.

  • Gentamicin is useful to the Gram negative bacterial infection, but its nephrotoxicity is a serious problem and the incidence is probably increasing. The toxicity of gentamicin to the kidney is site-specific to the proximal tubule. In this study, we measured daily peak and trough level of gentamicin, serum creatinine, serum $Beta_2$-microglobulin and 24-hr urine $Beta_2$-microglobulin in 10 gentamicin treated patients. All the patients had their peak levels of gentamicin in the safe therapeutic range, and their trough level showed no evidence of gentamicin accumulation. There was no patient who showed his daily serum creatinine and $Beta_2$-microglobulin rise significantly. But 24-hour urine $Beta_2$-microglobulin showed significant rise from basal level (mean $5.8{\pm}1.62{\times}$) on the 5 th day of gentamicin treatment. Thus, serial monitoring of proximal tubular function with urinary $Beta_2$-microglobulin excretion has potential value in the assessment of insults of gentamicin to this site. But clinical significance of raised urinary $Beta_2$-microglobulin excretion in relation to the serum creatinine should be further studied.

  • Objective: Dyslipidemia is recognized as a prominent risk factor for cardiovascular and cerebrovascular diseases but it is manageable through therapeutic and lifestyle intervention. Interpreting the latest guidelines is essential for an application of recommendation from guidelines into clinical practice. Therefore, this study aimed to compare the most recent guidelines on dyslipidemia treatment recommendations in Korea and USA. Methods: This study analyzed and compared 2015 Korean guidelines for the management of dyslipidemia, 2013 American College of Cardiology/American Heart Association (ACC/AHA) guideline and 2016 supportive guidelines from ACC. Results: A comparison was made focused on the following: target patients based on cardiovascular risk assessment, target goal, and treatment strategies including statin and non-statin therapies. Four target patient groups by risk were suggested in 2015 Korean guideline and cardiovascular risk factors were also considered for initiation of lipid lowering therapy. Titrated statin regimen was recommended by Korean guideline to reach LDL cholesterol and non-HDL cholesterol target level. In 2013 ACC/AHA guideline, four statin benefit group was introduced considering ASCVD risk and high intensity statin or intermediate intensity statin use were recommended without dose titration. 2016 update was to support non-statin therapy based on updated evidence and new consideration of ezetimibe, PCSK9-inhibitor and bile acid sequestrant was brought up. Conclusion: Guidelines are continuously updating as new and important clinical data are constantly released along with the advent of newly approved drugs for lipid disorder. This article provides resources that facilitates uptake of these recommendations into clinical practice.
