The brain is vulnerable to oxidative stress and inflammation that can occur as a result of aging or neurodegenerative diseases. Our work has sought to identify natural products that regulate heme oxygenase (HO)-1 and to determine their mechanism of action in neurodegenerative diseases. KCHO-1 is a novel herbal therapeutic containing 30% ethanol (EtOH) extracts from nine plants. In this study, we investigated the antineuroinflammatory effects of KCHO-1 in lipopolysaccharide- (LPS-) treated mouse BV2 microglia. KCHO-1 inhibited the protein expression of inducible nitric oxide synthase (iNOS), iNOS-derived nitric oxide (NO), cyclooxygenase- (COX-) 2, and COX-2-derived prostaglandin E2 (PGE2) in LPS-stimulated BV2 microglia. It also reduced tumor necrosis factor-α (TNF-α), interleukin-1β (IL-1β), and IL-6 production. This effect was correlated with the suppression of inhibitor of nuclear factor kappa B-α (IκB-α) phosphorylation and degradation and nuclear factor kappa B (NF-κB) translocation and DNA binding. Additionally, KCHO-1 upregulated HO-1 expression by promoting nuclear translocation of nuclear factor E2-related factor 2 (Nrf2) in mouse BV2 microglia. Tin protoporphyrin (SnPP), an HO activity inhibitor, was used to verify the inhibitory effects of KCHO-1 on proinflammatory mediators and proteins associated with HO-1 expression. Our data suggest that KCHO-1 has therapeutic potential in neurodegenerative diseases caused by neuroinflammation.

Objective:This study was performed to analyze the singledose toxicity of Aconitum kusnezoffii Reichb. pharmacopuncture (AKRP).Methods:All experiments were conducted at the Korea Testing & Research Institute (KTRI), an institute authorized to perform non-clinical studies, under the regulations of Good Laboratory Practice (GLP). Twenty (20) Sprague-Dawley rats were chosen for the pilot study. The animals were divided into four groups of five animals per group: group 1 (G1) being the control group with each animal receiving an injection of 0.3 ml of saline and groups 2, 3, and 4 (G2, G3, and G4) being the experimental groups with each animal receiving an injection of 0.1, 0.2 or 0.3 ml of AKRP, respectively. This study was conducted with the approval of the Institutional Animal Ethics Committee.Results:No deaths occurred in any of the 4 groups, and the LD50 of AKRP administered via IV was higher than 1.77 ml/kg. Some changes in the weights of the male rates were observed between the control group and the experimental groups, but no significant differences were noted in the weights of the female rats. To check for abnormalities in organs and tissues, we stained representative sections of each specified organ with Hematoxylin & Eosin for light microscopic examination.The results showed no significant differences in any of the organs or tissues.Conclusions:The above findings suggest that Aconitum kusnezoffii Reichb. pharmacopuncture is a relatively safe treatment. Further studies on the subject should be conducted to yield more concrete evidence.

The purpose of this study was to report an anaphylaxis after treated with Bee-venom acupuncture. Anaphylaxis is a clinical syndrome characterized by the acute system reaction of multiple organ systems to an IgE-mediated immunologic mediator release in previously sensitized individuals. We investigated the patients who had injected with Bee-venom in our clinic from March 2, 2014 to May 30, 2015. and two patients of anaphylaxis treated by Bee-Venom acupuncture were observed. One case of anaphylaxis was expressed clinically hypotension drowsy mentality, dyspnea, vomiting and so on. The other case was expressed itching sensation, urticaria, breathlessness, abdominal pain and so on. Based on this case, Bee venom-induced anaphylaxis can occur although preceding reactions are local or mild systemic ones. So, Korean medical doctor using Bee-Venom acupuncture must be prepare the system consider a countermeasure by anaphylaxis.

BackgroundAmyotrophic lateral sclerosis (ALS) is a fatal neurodegenerative disease that causes paralysis of limb, swallowing, and breathing muscles. Riluzole, the Food and Drug Administration-approved drug for ALS, provides minimal benefit, prolonging patient life by only 2–3 months. Previous studies have found a neuro-protective and anti-neuroinflammatory effect of Mecasin, with retrospective studies providing suggestive evidence for a beneficial effect of Mecasin. The aim of this study was to develop a protocol to determine the proper dosage of Mecasin.MethodsThis is a phase II-A, multi-center, randomized study with three arms. Thirty-six patients with ALS will be randomly assigned to one of three groups, each receiving the standard treatment with 100 mg of riluzole in addition to one of 1.6 g of Mecasin, 2.4 g of Mecasin, or a placebo. The Primary outcome is the Korean version of the Amyotrophic Lateral Sclerosis Functional Rating Scale-Revised result after 12 weeks of treatment. Secondary outcomes include results of the Short Form Health Survey-8, Medical Research Council Scale, Visual Analogue Scale for Pain, Hamilton Rating Scale for Depression, Fatigue Severity Scale, Patient Global Impression of Change, pulmonary function test, forced expiratory volume in 1 s and its ratio to forced vital capacity, creatine kinase, and body weight. The frequencies of total adverse events and serious adverse events will be described and documented. The trial protocol has been approved by the Institutional Review Board of the Wonkwang University Gwangju and Sanbon Hospital (2016–5-4 and 2016–34-01, respectively). An Investigational New Drug status (30731) was granted by the Korea Food and Drug Administration.DiscussionThis trial will aim to identify the optimal dosage of Mecasin. Additionally, it will test the efficacy and safety of Mecasin in conjunction with standard treatment, riluzole, for alleviating the functional decline in patients with ALS.Trial registrationKorean National Clinical Trial Registry CRIS; KCT0001984.
