Introduction Jaundice is one of the most common conditions found in neonatal period. Phototherapy is one of the main treatments for neonatal jaundice. However, several adverse effects of the phototherapy have been reported, including DNA damage recently. Therefore, a variety of treatments have been conducted to shorten the duration of phototherapy. Meanwhile, it has been hardly tried to prevent neonatal jaundice, but diverse approaches have been tried in traditional Chinese medicine (TCM) for many years. Therefore, this study aims to analyze the studies for the treatments to prevent neonatal jaundice based on TCM. Materials and Methods Various literatures have been searched via CNKI, and PubMed using the terms "neonatal jaundice" (新生儿黄疸, 胎黃, 胎疸) in category of 'Traditional Chinese Medicine', 'Traditional Chinese Medicinal Herbs' and 'Combination of Traditional Chinese Medicine With Western Medicine'. The search range included randomized controlled trials (RCTs), controlled clinical trials (CCTs), case reports, reviews and animal experiments published from 2013 to 2015. Results A total of 104 studies were found. 93 articles were excluded by reviewing the titles and abstracts. Out of the remaining 11 studies, 9 articles were RCTs, 2 articles were CCTs. The treatment used in neonatal babies in the studies were, using herbal remedies (meditation 5, bath 3 and retention enema 1) and the acupressure. All treatments were initiated within the first 24-48 hours after their birth. Then, there was a study that the subjects taken the herbal medicine were women during pregnancy. The outcome assessments used were the serum total bilirubin (TB), transcutaneous bilirubin measurement (TCB), the incidence of the hyperbilirubinemia, the duration time of the jaundice. Especially, TB, TCB and the incidence of the hyperbilirubinemia have decreased significantly more than that of the control group in the most of the results. No severe adverse events were reported in all articles reviewed. Conclusions Conventional treatment such as, herbal medicine in TCM, seems to be the effective way to prevent neonatal jaundice or hyperbilirubinemia. Therefore, the conventional treatment may be favorable choice for preventive treatment for neonatal jaundice.

In this case, we report a case of Soeumin rectal cancer patient who was mistreated with herb medication. This patient was 72 years old female diagnosed rectal cancer stage IV with multiple liver, lung, and LN metastases. She administered our cancer center in Sep. 2011 for cancer treatment, we diagnosed this patient as Taeyangin at first, and treated with Mihuedungsikjang-tang. After 1 week, she complained upper abdominal discomfort, severe abdominal pain, nausea and sweating. Considering several symptoms and conditions, the change of symptoms seemed to a adverse events caused by mistreatment. We re-diagnosed this patient as Soeumin, and treated with Soeumin herbal medication, Baekhaoleejung-tang(白何烏理中湯) and Hyangsayangyi-tang(香砂養胃湯). Several symptoms including abdominal pain were improved 2 weeks later. Therefore, we report this case as a reference that Soeumin misdiagnosed as Taeyangin and the improvement of adverse symptoms.

This review examined recently published (July 2014 to June 2017), randomized controlled trials (RCTs) which investigated the safety and effectiveness of combined Korean medicine/complementary alternative medicine (CAM) and Western medicine, to indicate the direction for integrative medical practice. The Korean Medicine Convergence Research Information Center evidence-based medicine database (KMCRIC EBM DB) was used to retrieve relevant RCTs indexed in the last 3 years. Study design, country, sample size, disease/condition with the Korean Standard Classification of Diseases code, interventions, direction of outcomes, and adverse events were extracted and summarized. A total of 93 RCTs were included in this review. Acupuncture/moxibustion was the most commonly used intervention (n = 47; 51%), and 19% (n = 18) of the studies treated musculoskeletal disorders, followed by circulatory disorders (n = 16; 17%), and mental and behavioral disorders (n = 9; 10%). Integrative treatment was reported as more effective than monotherapy in approximately 83% of these studies. Adverse events were poorly reported in most studies. This review suggests that integrative treatments are feasible, effective, and safe for various diseases/conditions, based on the evidence from recently published RCTs. Future studies on integrative healthcare are warranted.

Objectives: The present study investigated the potential adverse effects of multi-wall carbon nanotubes (MWCNTs) on pregnant dams and embryonic development following maternal exposure in rats. Methods: MWCNTs were orally administered to pregnant rats from gestational day (GD) 6 through 19 at dose levels of 0, 8, 40, 200, and 1000 mg/kg/day. During the test period, clinical signs, mortality, body weights, food consumption, serum biochemistry, oxidant-antioxidant status, gross findings, organ weights, and Caesarean section findings were examined. Results: All animals survived to the end of the study. A decrease in thymus weight was observed in the highest dose group. However, maternal body weight, food consumption, serum biochemical parameters, and oxidant-antioxidant balance in the kidneys were not affected by treatment with MWCNTs. No treatment-related differences in gestational index, embryo-fetal mortality, or fetal and placental weights were observed between treated and control groups. Conclusions: The results show that 14-day repeated oral dosing of MWCNTs during pregnancy induces minimal maternal toxicity at 1000 mg/kg/day in rats. Under these experimental conditions, the no-observed-adverse-effect level of MWCNTs is considered to be 200 mg/kg/day for dams and 1000 mg/kg/day for embryonic development.

The red imported fire ant is considered one of the most notorious invasive species because of its adverse impact on both humans and ecosystems. Public concern regarding red imported fire ants has been increasing, as they have been found seven times in South Korea. Even if red imported fire ants are not yet colonized in South Korea, a proper quarantine plan is necessary to prevent their widespread distribution. As a basis for quarantine planning, we modeled the potential distribution of the red imported fire ant under current climate conditions using six different species distribution models (SDMs) and then selected the random forest (RF) model for modeling the potential distribution under climate change. We acquired occurrence data from the Global Biodiversity Information Facility (GBIF) and bioclimatic data from WorldClim. We modeled at the global scale to project the potential distribution under the current climate and then applied models at the local scale to project the potential distribution of the red imported fire ant under climate change. Modeled results successfully represent the current distribution of red imported fire ants. The potential distribution area for red imported fire ants increased to include major harbors and airports in South Korea under the climate change scenario (RCP 8.5). Thus, we are able to provide a potential distribution of red imported fire ant that is necessary to establish a proper quarantine plan for their management to minimize adverse impacts of climate change.

As various populations are rapidly becoming an aging society worldwide and interest in health issues has increased, demand for functional foods including herbal products has increased markedly to maintain a healthy state which has led to safety issues about their intake as an inevitable result. The objective of this study was to identify the safety profile of a Korean red ginseng and Salvia plebeia R. Br. extract mixture (KGC-03-PS) which is a valuable ingredient that can be used as a functional food. In the present study, the subacute oral toxicity and bacterial reverse mutagenicity of KGC-03-PS were evaluated. Sprague Dawley rats were administered KGC-03-PS orally for 28 days by gavage. Daily KGC-03-PS dose concentrations were 0, 500, 1,000, or 2,000 mg/kg body weight (bw) per day. Bacterial reverse mutation test with KGC-03-PS dose levels ranging from 312.5 to $5,000{\mu}g/plate$ was carried out by OECD test guideline No. 471. Five bacterial strains (Salmonella typhimurium TA98, TA100, TA1535, TA1537, and Escherichia coli WP2) were tested in the presence or absence of metabolic activation by plate incorporation method. There were no toxicological effects related with test substance in the clinical evaluation of subacute oral toxicity test including clinical signs, body weight, and food consumption. Moreover, no toxicological changes related to KGC-03-PS were observed in the hematological and serum biochemical characteristics as well as in the pathological examinations, which included organ weight measurements and in the gross- or histopathological findings. KGC-03-PS did not induce an increase in the number of revertant colonies in all bacterial strains of the bacterial reverse mutation test. The no-observed-adverse-effect level of KGC-03-PS is greater than 2,000 mg/kg bw/day, and KGC-03-PS did not induce genotoxicity related to bacterial reverse mutations under the conditions used in this study.

Going back to basics prior to mentioning the use of antipsychotics in patients with pain, the International Association for the Study of Pain (IASP) definition of pain can be summarized as an unpleasant experience, composed of sensory experience caused by actual tissue damage and/or emotional experience caused by potential tissue damage. Less used than antidepressants, antipsychotics have also been used for treating this unpleasant experience as adjuvant analgesics without sufficient evidence from research. Because recently developed atypical antipsychotics reduce the adverse reactions of extrapyramidal symptoms, such as acute dystonia, pseudo-parkinsonism, akathisia, and tardive dyskinesia caused by typical antipsychotics, they are expected to be used more frequently in various painful conditions, while increasing the risk of metabolic syndromes (weight gain, diabetes, and dyslipidemia). Various antipsychotics have different neurotransmitter receptor affinities for dopamine (D), 5-hydroxytryptamine (5-HT), adrenergic (${\alpha}$), histamine (H), and muscarinic (M) receptors. Atypical antipsychotics antagonize transient, weak $D_2$ receptor bindings with strong binding to the $5-HT_{2A}$ receptor, while typical antipsychotics block long-lasting, tight $D_2$ receptor binding. On the contrary, antidepressants in the field of pain management also block the reuptake of similar receptors, mainly on the 5-HT and, next, on the norepinephrine, but rarely on the D receptors. Antipsychotics have been used for treating positive symptoms, such as delusion, hallucination, disorganized thought and behavior, perception disturbance, and inappropriate emotion, rather than the negative, cognitive, and affective symptoms of psychosis. Therefore, an antipsychotic may be prescribed in pain patients with positive symptoms of psychosis during or after controlling all sensory components.

Objective: Human exposure to multiple xenobiotics, over various developmental windows, results in adverse health effects arising from these concomitant exposures. Humans are widely exposed to bisphenol A, and acetaminophen is the most commonly used over-the-counter drug worldwide. Bisphenol A is a well-recognized male reproductive toxicant, and increasing evidence suggests that acetaminophen is also detrimental to the male reproductive system. The recent recognition of male reproductive system dysfunction in conditions of suboptimal reproductive outcomes makes it crucial to investigate the contributions of toxicant exposures to infertility and sub-fertility. We aimed to identify toxicity in the male reproductive system at the mitochondrial level in response to co-exposure to bisphenol A and acetaminophen, and we investigated whether melatonin ameliorated this toxicity. Methods: Male Wistar rats were divided into six groups (n=10 each): a control group and groups that received melatonin, bisphenol A, acetaminophen, bisphenol A and acetaminophen, and bisphenol A and acetaminophen with melatonin treatment. Results: Significantly higher lipid peroxidation was observed in the testicular mitochondria and sperm in the treatment groups than in the control group. Levels of glutathione and the activities of catalase, glutathione peroxidase, glutathione reductase, and manganese superoxide dismutase decreased significantly in response to the toxicant treatments. Likewise, the toxicant treatments significantly decreased the sperm count and motility, while significantly increasing sperm mortality. Melatonin mitigated the adverse effects of bisphenol A and acetaminophen. Conclusion: Co-exposure to bisphenol A and acetaminophen elevated oxidative stress in the testicular mitochondria, and this effect was alleviated by melatonin.

Mesenchymal stem cells (MSCs) are effective in treating autoimmune diseases and managing various conditions, such as engraftment of allogeneic islets. Additionally, autologous and HLA-matched allogeneic MSCs can aid in the engraftment of human allogeneic kidneys with or without low doses of tacrolimus, respectively. However, HLA alloantigens are problematic because cell therapy uses more HLA-mismatched allogeneic cells than autologous for convenience and standardization. In particular, HLA-mismatched MSCs showed increased Ag-specific T/B cells and reduced viability faster than HLA-matched MSCs. In CRISPR/Cas9-based cell therapy, Cas9 induce T cell activation in the recipient's immune system. Interestingly, despite their immunogenicity being limited to the cells with foreign Ags, the accumulation of HLA alloantigen-sensitized T/B cells may lead to allograft rejection, suggesting that alloantigens may have a greater scope of adverse effects than foreign Ags. To avoid alloantigen recognition, the β2-microglobulin knockout (B2MKO) system, eliminating class-I MHC, was able to avoid rejection by alloreactive CD8 T cells compared to controls. Moreover, universal donor cells in which both B2M and Class II MHC transactivator (CIITA) were knocked out was more effective in avoiding immune rejection than single KO. However, B2MKO and CIITA KO system remain to be controlled and validated for adverse effects such as the development of tumorigenicity due to deficient Ag recognition by CD8 T and CD4 T cells, respectively. Overall, better HLA-matching or depletion of HLA alloantigens prior to cell therapy can reduce repetitive transplantation through the long-term survival of allogeneic cell therapy, which may be especially important for patients seeking allogeneic transplantation.
