[PMID: 33663582 PMCID: PMC7934479 DOI: 10.1186/s13063-021-05135-6] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/01/2020] [Accepted: 02/16/2021] [Indexed: 11/10/2022] Open
Abstract
BACKGROUND Dangguixu-san (DS), a herbal extract, is widely used in Korean medicine to treat pain and swelling caused by ankle sprain. However, there is insufficient evidence regarding the effects of DS on ankle sprains. Accordingly, we assessed the efficacy and safety of DS for the treatment of acute lateral ankle sprain (ALAS). METHODS This study was a multicenter (two Korean hospitals), randomized, double-blind, placebo-controlled, parallel-arm clinical trial with a 1:1 allocation ratio that included a per-protocol analysis and sub-analysis based on symptom severity. Forty-eight participants (n = 28 at Semyung University Korean Medicine Hospital in Chungju; n = 20 at DongShin University Gwangju Korean Medicine Hospital) with grade I or II ALAS that occurred within 72 h before enrollment were randomized to a DS (n = 24) or placebo (n = 24) group. Both groups received acupuncture treatment once daily for 5 consecutive days and the trial medication (DS/placebo capsule) three times a day for 7 consecutive days. Primary (visual analog scale [VAS] scores for pain) and secondary (Foot and Ankle Outcome Scores [FAOS], edema, and European Quality of Life Five-Dimension-Five-Level Scale [EQ-5D-5L] scores) outcome measures were recorded at baseline (week 0), the end of the intervention (week 1), and 4 weeks after treatment completion (week 5). RESULTS Forty-six participants completed the trial (n = 23 each). Changes in VAS scores, FAOS Symptom/Rigidity, and FAOS Ache from week 1 to week 5 showed significant differences between the two groups. Sub-analyses showed significant differences in changes of FAOS Ache (week 0 to week 5) and VAS scores, total FAOS, and EQ-5D-5L scores (week 1 to week 5) between the two subgroups (grade II). There were no adverse events and significant negative changes in clinical laboratory parameters in both groups. CONCLUSIONS Overall, the results of this study are in favor of DS combined with acupuncture and suggest that DS combined with acupuncture is a safe treatment with positive long-term effects in terms of pain reduction and symptom alleviation in patients with grade I or II ALAS.

Curr Pharm Des 2020; 26:2591-2601. [DOI: 10.2174/1381612826666200318152049] [Citation(s) in RCA: 8] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/08/2019] [Accepted: 02/28/2020] [Indexed: 02/07/2023]
Abstract
Background and objective:
Atherosclerosis is one of the leading causes of human morbidity globally
and reduced bioavailability of vascular nitric oxide (NO) has a critical role in the progression and development of
the atherosclerotic disease. Loss of NO bioavailability, for example via a deficiency of the substrate (L-arginine)
or cofactors for endothelial nitric oxide synthase (eNOS), invariably leads to detrimental vascular effects such as
impaired endothelial function and increased smooth muscle cell proliferation, deficiency of the substrate (Larginine)
or cofactors for eNOS. Various medicinal plants and their bioactive compounds or secondary metabolites
with fewer side effects are potentially implicated in preventing cardiovascular disease by increasing NO
bioavailability, thereby ameliorating endothelial dysfunction. In this review, we describe the most notable medicinal
plants and their bioactive compounds that may be appropriate for enhancing NO bioavailability, and
treatment of atherosclerosis.
Methods:
The material in this article was obtained from noteworthy scientific databases, including Web of Science,
PubMed, Science Direct, Scopus and Google Scholar.
Results:
Medicinal plants and their bioactive compounds influence NO production through diverse mechanisms
including the activation of the nuclear factor kappa B (NF-κB) signaling pathway, activating protein kinase C
(PKC)-α, stimulating protein tyrosine kinase (PTK), reducing the conversion of nitrite to NO via nitrate-nitrite
reduction pathways, induction of eNOS, activating the phosphatidylinositol 3-kinase (PI3K)/serine threonine
protein kinase B (AKT) (PI3K/AKT/eNOS/NO) pathway and decreasing oxidative stress.
Conclusion:
Medicinal plants and/or their constituent bioactive compounds may be considered as safe therapeutic
options for enhancing NO bioavailability and prospective preventative therapy for atherosclerosis.

Abstract
Headache after traumatic brain injury (TBI) is a common symptom which includes moderate-to-severe pain more than 5 years after the injury and severely limits the quality of life. Some guidelines have indicated that there are several cases where headaches do not respond adequately to conventional therapies. Therefore, effective alternative approaches are needed. In this case report, we present a 74-year-old woman, who had persistent headache attributed to traumatic injury to the head and subjective cognitive impairment. By using the Korean Medical (KM) treatment blood stasis-removing therapy using Dangguixu-san and auriculotherapy, her headache improved markedly. Improvements in the cognitive function and hemorrhage were also observed. This case report suggests that KM treatments using Dangguixu-san and auriculotherapy may be an alternative therapeutic approach for headache after TBI.

Abstract
OBJECTIVES Blood stasis is an important pathophysiologic concept in Traditional East Asian Medicine. It has been considered to be a pathogenic factor in chronic and incurable conditions such as pain, infertility, cancer, coronary heart disease, and others. The aim of this study was to investigate the effects of pain reduction by blood stasis treatment for blood stasis syndromes with traumatic injury. METHODS A single-center prospective pretest-post-test pilot study included 73 patients with a trauma that occurred within the past 2 weeks who were admitted into Jaseng Hospital of Korean Medicine from August 2015 through December 2015. Of the 50 patients analyzed in this study, 42 were women (mean age, 33.52). Triple Energizer-reinforcing Saam acupuncture set, herbal medicine (Dangkwisoo-san), and wet cupping on tender point, which are Korean medical therapies generally executed to treat post-traumatic pain, were performed. The patients had to receive at least six sessions of treatment during the 2 weeks, with subsequent treatment being performed within 3 ± 1 days after the previous treatment. Numeric rating scale (NRS) score and general pain severity indicator was measured as a primary outcome measure. The blood stasis questionnaire, oximetry, and patient's satisfaction were also measured. RESULTS The mean size of subcutaneous bleeding (width and length) and NRS score as a general pain indicator significantly decreased over the visits (all p < 0.01, visit 1 vs. visit 6). Among the blood stasis symptoms in the questionnaire, 11 blood stasis indicators significantly decreased (all p < 0.05). The patients showed significant improvement in the minimum and maximum value of peripheral perfusion index after the treatment (p = 0.011 and p = 0.15, respectively). CONCLUSIONS This study reveals that blood stasis treatment may help improve the pain of patients with traumatic injury by enhancing the peripheral blood flow. The significant results observed in this study support some evidence of the theories of diagnosing blood stasis pattern and treatments of that pattern in Korean Medicine.

Abstract
BACKGROUND Ankle sprain is a common musculoskeletal injury. In Korean medicine, blood stasis is thought to be the main cause of pain and swelling in patients with ankle sprain. Dangguixu-san (DS), a herbal extract, is widely used in Korean medicine for the treatment of traumatic ecchymosis and pain by promoting blood circulation and relieving blood stasis. However, the effects of DS on ankle sprain have not been evaluated in a randomized clinical trial. Here, we describe the protocol for a randomized controlled trial that will evaluate the efficacy and safety of DS for the treatment of ankle sprain. METHODS/DESIGN In this randomized, double-blinded, placebo-controlled, parallel-arm clinical trial with a 1:1 allocation ratio, participants (n = 48) with acute lateral ankle sprain (ALAS) that occurred within 72 h before enrollment will be randomly assigned to a DS (n = 24) or a placebo (n = 24) group. Both groups will receive acupuncture treatment once a day for 5 days a week (excluding Saturday and Sunday) and the trial medication (DS/placebo capsule) three times a day for seven consecutive days. The primary outcome measure will be pain relief evaluated using a Visual Analog Scale (VAS). Secondary outcome measures will include Foot and Ankle Outcome Scores (FAOS), edema, European Quality of Life Five-Dimension-Five-Level Scale (EQ-5D-5 L) scores, and the number of recurrent ankle sprains. VAS, FAOS, edema, and EQ-5D-5 L scores will be recorded before, at the end of, and at 4 weeks after treatment completion. EQ-5D-5 L scores will be additionally recorded at 26 weeks after treatment completion. The number of recurrent ankle sprains will be recorded at 4, 8, 12, and 26 weeks after treatment completion. DISCUSSION This study is expected to provide evidence regarding the efficacy, safety, and usefulness of DS for the treatment of ALAS.

Abstract
Although hundreds of promising substances have been tested in clinical trials,
thrombolysis currently remains the only specific pharmacological treatment for
ischemic stroke. Poor quality, e.g. low statistical power, in the preclinical
studies has been suggested to play an important role in these failures. Therefore,
it would be attractive to use animal models optimized to minimize unnecessary
mortality and outcome variability, or at least to be able to power studies more
exactly by predicting variability and mortality given a certain experimental setup.
The possible combinations of methodological parameters are innumerous, and an
experimental comparison of them all is therefore not feasible. As an alternative
approach, we extracted data from 334 experimental mouse stroke articles and, using a
hypothesis-driven meta-analysis, investigated the method parameters’
impact on infarct size variability and mortality. The use of Swiss and C57BL6 mice
as well as permanent occlusion of the middle cerebral artery rendered the lowest
variability of the infarct size while the emboli methods increased variability. The
use of Swiss mice increased mortality. Our study offers guidance for researchers
striving to optimize mouse stroke models.

Abstract
Brain microvascular endothelial cells form the interface between nervous tissue and circulating blood, and regulate central nervous system homeostasis. Brain microvascular endothelial cells differ from peripheral endothelial cells with regards expression of specific ion transporters and receptors, and contain fewer fenestrations and pinocytotic vesicles. Brain microvascular endothelial cells also synthesize several factors that influence blood vessel function. This review describes the morphological characteristics and functions of brain microvascular endothelial cells, and summarizes current knowledge regarding changes in brain microvascular endothelial cells during stroke progression and therapies. Future studies should focus on identifying mechanisms underlying such changes and developing possible neuroprotective therapeutic interventions.

Abstract
The interstitial cells of Cajal (ICCs) are the pacemaker cells in the gastrointestinal (GI) tract. In the present study, the effects of Dangkwisoo‑san (DS) on pacemaker potentials in cultured ICCs from the small intestine of the mouse were investigated. The whole‑cell patch‑clamp configuration was used to record pacemaker potentials from cultured ICCs and the increase in intracellular Ca2+ concentration ([Ca2+i) was analyzed in cultured ICCs using fura‑2‑acetoxymethyl ester. The generation of pacemaker potentials in the ICCs was observed. DS produced pacemaker depolarizations in a concentration dependent manner in current clamp mode. The 4‑diphenylacetoxy‑N‑methyl‑piperidine methiodide muscarinic M3 receptor antagonist inhibited DS‑induced pacemaker depolarizations, whereas methoctramine, a muscarinic M2 receptor antagonist, did not. When guanosine 5'‑[β‑thio] diphosphate (GDP‑β‑S; 1 mM) was in the pipette solution, DS marginally induced pacemaker depolarizations, whereas low Na+ solution externally eliminated the generation of pacemaker potentials and inhibited the DS‑induced pacemaker depolarizations. Additionally, the nonselective cation channel blocker, flufenamic acid, inhibited the DS‑induced pacemaker depolarizations. Pretreatment with Ca2+‑free solution and thapsigargin, a Ca2+‑ATPase inhibitor in the endoplasmic reticulum, also eliminated the generation of pacemaker currents and suppressed the DS‑induced pacemaker depolarizations. In addition, [Ca2+]i analysis revealed that DS increased [Ca2+]i. These results suggested that DS modulates pacemaker potentials through muscarinic M3 receptor activation in ICCs by G protein‑dependent external and internal Ca2+ regulation and external Na+. Therefore, DS were observed to affect intestinal motility through ICCs.

Abstract
BACKGROUND Dangguisu-san (DGSS) has been widely used to treat ecchymosis, blood stagnation and pain resulting from physical shock in Korea. OBJECTIVE A high-performance liquid chromatography-photodiode array detection (HPLC-PDA) method for simultaneous analysis of nine components, albiflorin (1), paeoniflorin (2), liquiritin (3), nodakenin (4), coumarin (5), liquiritigenin (6), cinnamic acid (7), cinnamaldehyde (8), and glycyrrhizin (9) in DGSS extract has been developed for the first time. MATERIALS AND METHODS The analytical column for separation of the nine constituents used a Gemini C18 column kept at 40°C by the gradient elution with 1.0% (v/v) acetic acid in water and 1.0% (v/v) acetic acid in acetonitrile as mobile phase. The flow rate was 1.0 mL/min and the injection volume was 10 μL. RESULTS Calibration curves of all compounds showed good linearity (r (2) ≥ 0.9999) within the test ranges. The limits of detection and quantification for all analytes were 0.01-0.27 μg/mL and 0.04-0.89 μg/mL, respectively. All recoveries of the nine marker compounds were 96.62-102.47% with relative standard deviations (RSD) <1.72%. The RSDs of intra-day and inter-day precision were <1.32% and 1.61%, respectively. The amounts of the nine marker components ranged from 0.10 mg/g to 13.71 mg/g. CONCLUSION The developed and validated HPLC-PDA method may help for the quality control of DGSS.

Abstract
Oxysophoridine, a new alkaloid extracted from Sophora alopecuroides L., has been shown to have a protective effect against ischemic brain damage. In this study, a focal cerebral ischemia/reperfusion injury model was established using middle cerebral artery occlusion in mice. Both 62.5, 125, and 250 mg/kg oxysophoridine, via intraperitoneal injection, and 6 mg/kg nimodipine, via intragastric administration, were administered daily for 7 days before modeling. After 24 hours of reperfusion, mice were tested for neurological deficit, cerebral infarct size was assessed and brain tissue was collected. Results showed that oxysophoridine at 125, 250 mg/kg and 6 mg/kg nimodipine could reduce neurological deficit scores, cerebral infarct size and brain water content in mice. These results provided evidence that oxysophoridine plays a protective role in cerebral ischemia/reperfusion injury. In addition, oxysophoridine at 62.5, 125, and 250 mg/kg and 6 mg/kg nimodipine increased adenosine-triphosphate content, and decreased malondialdehyde and nitric oxide content. These compounds enhanced the activities of glutathione-peroxidase, superoxide dismutase, catalase, and lactate dehydrogenase, and decreased the activity of nitric oxide synthase. Protein and mRNA expression levels of N-methyl-D-aspartate receptor subunit NR1 were markedly inhibited in the presence of 250 mg/kg oxysophoridine and 6 mg/kg nimodipine. Our experimental findings indicated that oxysophoridine has a neuroprotective effect against cerebral ischemia/reperfusion injury in mice, and that the effect may be due to its ability to inhibit oxidative stress and expression of the N-methyl-D-aspartate receptor subunit NR1.

Abstract
Global cerebral ischemia, such as occurs following cardiac arrest, can lead to oxidative stress, hippocampal neuronal cell death, and cognitive defects. The current study examined the potential beneficial effect and underlying mechanisms of post-treatment with the naturally occurring isoflavonic phytoestrogen, genistein, which has been implicated to attenuate oxidative stress. Genistein (1 mg kg(-1)) was administered i.v. 5 min after reperfusion in rats subjected to four-vessel global cerebral ischemia (GCI). The results revealed that genistein exerted significant neuroprotection of hippocampal CA1 neurons following GCI, as evidenced by an increase in NeuN-positive neurons and the decrease in TUNEL-positive neurons. Furthermore, genistein treatment also resulted in significantly improved spatial learning and memory as compared to vehicle control animals. The beneficial effects of genistein appear to be mediated by an increase of phosphorylation/activation of eNOS, with subsequent activation of the antioxidant/detoxification Nrf2/Keap1 transcription system. Along these lines, genistein increased keap1 S-nitrosylation, with a corresponding nuclear accumulation and enhanced DNA binding activity of Nrf2. Genistein also enhanced levels of the Nrf2 downstream antioxidant protein, heme oxygenase (HO)-1, as compared to vehicle control groups. In accordance with its induction of Nrf2 activation, genistein exerted a robust attenuation of oxidative DNA damage and lipid peroxidative damage in hippocampal CA1 neurons after GCI, as measured by immunofluorescence staining of the oxidative stress markers, 8-hydroxy-2-deoxyguanosine (8-OHdG) and 4-Hydroxynonenal (4-HNE). Interestingly, the aforementioned effects of genistein were abolished by pretreatment with L-NAME, an inhibitor of eNOS activation. In conclusion, the results of the study demonstrate that low dose genistein can exert significant antioxidant, neuroprotective, and cognitive-enhancing effects in the hippocampal CA1 region following GCI. Mechanistically, the beneficial effects of genistein appear to be mediated by enhanced eNOS phosphorylation/activation and nitric oxide (NO)-mediated thiol modification of Keap1, with subsequent upregulation of the Nrf2/HO-1 antioxidative signaling pathway and a resultant attenuation of oxidative stress.

Dangkwisoo-san, an herbal medicinal formula, ameliorates acute lung inflammation via activation of Nrf2 and suppression of NF-κB. JOURNAL OF ETHNOPHARMACOLOGY 2012; 140:107-16. [PMID: 22230470 PMCID: PMC3616192 DOI: 10.1016/j.jep.2011.12.043] [Citation(s) in RCA: 21] [Impact Index Per Article: 1.8] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Subscribe] [Scholar Register] [Received: 09/07/2011] [Revised: 12/18/2011] [Accepted: 12/26/2011] [Indexed: 05/26/2023]
Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Dangkwisoo-san (DS), an herbal medicinal formula, has long been used in Korea for the treatment of inflammatory complications caused by physical trauma. Although the therapeutic effect of DS is likely associated with anti-inflammatory activity, the precise underlying mechanisms are largely unknown. Here we sought to elucidate the possible mechanisms of anti-inflammatory activity of DS. MATERIALS AND METHODS The water extract of DS was orally fed to C57BL/6 mice for 14 days prior to LPS intranasal instillation for lung inflammation. The effects of DS on lung inflammation were determined by differential cell counting, lung histology, and semi-quantitative RT-PCR of lung sections. The effects of DS on the activities of Nrf2 and NF-κB were assessed by western blotting, semi-quantitative RT-PCR, and luciferase reporter assays in RAW 264.7, an NF-κB reporter cell line, and HEK 293 transfected with an NF-κB reporter construct. RESULTS Mice that were treated with a water extract of DS showed significant attenuation of lung inflammation induced by intranasal lipopolysaccharide (LPS) compared to control mice treated with vehicle. In vitro experiments show that DS activated Nrf2, an anti-oxidant transcription factor that protects from various inflammatory diseases, and induced Nrf2-regulated genes including GCLC, NQO-1 and HO-1. In addition, DS suppressed NF-κB activity and reduced the production of pro-inflammatory cytokines. Transfection experiment indicates that inhibition of NF-κB likely occurred upstream of IKK complex. Furthermore, DS enhanced the expression of HO-1 and suppressed that of IL-1β and TNF-α in inflamed mouse lungs. CONCLUSIONS These results suggest that the therapeutic effects of DS are related with suppression of inflammation, which is, at least in part, mediated by activation of anti-inflammatory factor Nrf2 and inhibition of pro-inflammatory factor NF-κB.
