Antidolary active and anti-sugar mechanisms of the ova family (石斛; Dendrobii herba) ethanol extract (EED) were investigated. The EED was administered orally four times a day in a diabetic mouse induced by strepto Joe Toshin to reveal and reveal its pharmacological miracle through experimental studies that reduce the liver function of empty blood sugar, glythamic oxal acetate levels, insulin levels and glutamic acid trans aminaase and glutamic acid pyruvic acid trans amine. EED increased insulin secretion by glucose in RINm5F beta cells as well as intraperitoneal glucose intakes in L6 muscle cells. Thus, EED has shown great promise in displaying anti-diabetes activity not only by increasing insulin secretion but also by increasing intakes per cell, and hopes that future research on pharmacological mechanisms for quartz (Dendrobii herba) ethanol extract will be more active and contribute greatly to the treatment of diabetes.

Ginsenosides are active constituents of ginseng (Panax ginseng) that have possible anti-aging, physiological and pharmacological activities, such as anti-cancer and anti-inflammatory effects. Although the ginseng root is generally used more often than the aerial parts for medicinal purposes, the flowers also contain numerous ginsenosides, including Rb2, Rc, Rd, Re and Rg1. Therefore, an extract from the flowers of the P. ginseng could have the pharmacological efficacy of bioactive compounds including ginsenosides. The high hydrostatic pressure extraction (HHPE) is a method that is used for the efficient extraction of bioactive compounds from plant materials. In this study, we compared the yield of ginsenosides from ginseng flowers under different conditions of extraction pressure and time of HHPE. The results indicate that the total yield of the ginsenosides improved as the pressure increased from 0.1 to 80 MPa and treatment duration increased to 24 hours. In addition, the ginsenoside extracts from HHPE at 80 MPa, which possessed a higher total ginsenoside concentration, decreased the viability of the primary human epidermal keratinocytes (HEKs) significantly than the ginsenoside extracts from HHPE at 0.1 MPa. Collectively, we found that the method of HHPE that was performed for 24 hours at 80 MPa showed the highest yield of ginsenosides from the flowers of P. ginseng. In addition, our study provides a foundation for the efficient extraction of ginsenosides, which had a potent bioactivity, from flowers of P. ginseng through HHPE.

Scutellaria baicalensis Georgi (SB) has been widely studied to treat inflammatory diseases in east Asia. In the recent years, many studies have focused on modifying herbs to increase the pharmacological effects. Roasting alcohol absorbed SB is one of the traditional methods to increase the therapeutic effects. Currently there are no reports on the pharmacological effects of roasted SB. This study investigated the anti-inflammatory effects of roasted 30% ethyl alcohol absorbed SB extract (SR) on mice ear edema. After intra-gastric injection of dexamethasone (for positive control, 2 mg/kg) and SR (50, 100, 400 mg/kg), ear edema was provoked by croton oil (5% v/v in acetone, 10 ul/ear). Ear thickness was measured with a digital caliper to quantify the change in swelling. For histological study, we made paraffin sections and performed Phloxine-Tartrazine staining and Masson's trichrome staining to observe epidermis, dermis and subcutaneous region and collagen fiber of mice ear tissues. Ear thickness decreased dose-dependent manner in SR treated groups. Histological analysis compared with dexamethasone treated group, SR treated groups demonstrated a similar reduction in hypoplasia of epidermis and influx of inflammatory cells. Increase of subcutaneous layer and decrease of collagen fibers were significantly recovered in SR treated group (400 mg/kg) and dexamethasone treated group. In conclusion, treatment with SR ameliorates auricular inflammation induced with croton oil in mice. Experiments are now underway to understand the molecular mechanisms underlying anti-inflammatory activities of SR.

Objectives : This study was conducted to suggest new alternative methods to improve pharmacopuncture and Korean medicine research by analyzing the injection route, pharmacological effect, and status studies of Chinese herbal injections. Methods : 130 types of marketed and licensed Chinese herbal injection were searched from National Medical Products Administration (NMPA) of China. CNKI, PubMed, EMBASE, and the 2020 edition of the Chinese Pharmacopoeia were used to collect additional information. 'Herbal injection' and 'Chinese herbal injection' were used as keywords. All data were collected mainly on the treatment of Chinese herbal injection. But data which were not related to the relevant research or Chinese herbal injection were excluded. Results : Intramuscular injection accounted for more than half of the single injection route (51%). Acupoint and intramuscular injections accounted for 55% of dual injection routes. Acupoint, intravenous, and intramuscular injections accounted for the largest proportion (76%) of the multiple routes of injections. As for the pharmacological effect, injection for cardiovascular diseases accounted for 29%. About the number of raw herbal materials, single herbal material was the most common. Twelve intervention studies all tested intravenous injections, and half of them investigated cardiocerebrovascular diseases. All were given by intravenous injection. In the side effect section, the most common symptoms were nausea and vomiting. Conclusions : Through the results, it is expected to be used for research and development of new pharmacopuncture and herbal medicine.

Boron Neutron Capture Therapy (BNCT) has the advantage of selectively removing cancer cells ingesting boron compounds. In this study, the benefits for treatment time and boron compound injection dose were compared between current neutron sources and a high current neutron sources to be developed in near future. The time-activity curve (TAC) of GBM (Glioblastoma) for one bolus injection was obtained by applying modified 3 compartment model. The treatment time was determined for an accelerator-based neutron sources at the present time and a high current accelerator based neutron source to be developed in the near future. In the case of the double amount of IAEA-recommended neutron flux, the treatment time was shortened to 15 minutes. In the case of high current accelerators, which are five times the amount of IAEA-recommended neutron flux, the irradiation time is within 5 minutes. The use of a high current accelerator based neutron source in BNCT is advantageous in terms of treatment time. In addition, it can increase the efficiency of use of neutrons and reduce the boron compound injection dose to patients, thus reducing pharmacological toxicity.

Background: The first dental experience is vital in molding a child's attitude towards dentistry and dental outcomes. The cooperation of a child during dental treatment is essential to render successful and high-quality treatment. Dental anxiety is common in children undergoing dental treatment. The success of pediatric dental treatments and patient comfort depends on controlling the levels of patient anxiety in clinical settings. This study aimed to compare the effectiveness of the recorded maternal voice and virtual cognitive tool (Roogies application) in the management of pediatric dental patients. Methods: The study was carried out with children aged of 4-7 years [n = 80, (40 male and 40 female)], without any past dental history, and were randomly allocated into two groups. After informed consent was obtained, the entire procedure was explained to the parents. Anxiety was assessed pre-, during, and post-treatment by measuring pulse rate, and recording Venham Picture Test (VPT) scores. Group A [n = 40; 20 boys and 20 girls)] was provided with a headphone that played a recorded maternal voice. Group B [n = 40; 20 boys and 20 girls)] was administered the virtual cognitive tool. After conditioning the children, oral prophylaxis was performed for both groups. A comparative evaluation was conducted for each treatment session. Results: The intra-group comparison of VPT scores and heart rate for patients assigned to the recorded maternal voice showed a statistically significant difference in dental anxiety (P-value ≤0.001). Conclusion: This study demonstrated that a reduction in dental anxiety with the help of recorded maternal voice forms an important component of non-pharmacological behavior management. Alternatively, the use of a virtual cognitive tool as an anxiety-reducing technique can also be advocated.

The seeds of Trichosanthes kirilowii (STK) used in traditional Oriental medicine for the treatment of dry cough and constipation have diverse pharmacological activities, including hypolipidemic, antioxidant, immunosuppressive, and anticancer effects. However, the effect of STK on angiogenesis has not been studied yet. In this study, we investigated whether the ethanolic extract of STK (ESTK) can regulate the migration and tube formation of human umbilical vein endothelial cells (HUVECs) and explored the underlying mechanism. Results of transwell assay showed that ESTK treatment dose-dependently suppressed the migration of HUVECs. The conditioned medium collected from H1299 human lung cancer cells was used as a chemoattractant. Our observation suggests that ESTK would inhibit the recruitment of endothelial cells into tumors. In addition, ESTK treatment significantly reduced the tube formation of HUVECs. As a molecular mechanism, we found that vascular endothelial growth factor (VEGF)-induced phosphorylation of VEGF receptor 2 (VEGFR2) was completely blocked by ESTK treatment. The expression of angiogenic factors, including VEGFA, fibroblast growth factor 2 (FGF2), angiopoietin, placental growth factor (PGF), platelet derived growth factor (PDGF), angiogenin, and tumor necrosis factor (TNF)-α, was commonly decreased by ESTK treatment in H1299 cells, indicating that ESTK would reduce the production of angiogenic factors from cancer cells. Taken together, our results clearly demonstrated that ESTK exhibited anti-angiogenic effects in HUVECs, which provides another possible mechanism underlying the anticancer activities of STK.

Objectives : This study used a network pharmacology approach to analyze the treatment mechanisms of Yijin-tang on Meniere's disease, and comparative analysis the treatment mechanisms of drugs recommended in the Meniere's disease treatment guidelines. Methods : We collected information on the recommended drugs from the Meniere's disease treatment guidelines and their target proteins were screened via the STITCH database. The intersection targets were obtained through Venny 2.1.0. Gene Ontology(GO) analysis and Kyoto Encyclopedia of Genes and Genomes(KEGG) pathway analysis were performed using ClueGO. Results : The 7 proteins(TNF, CASP9, PARP1, CCL2, CFTR, NOS2, NOS1) were associated with both Yijin-tang and Meniere's disease related genes. The 10 proteins(AQP2, KCNE1, AQP1, AVP, ACE, HRH1, HRH3, NOS1, CA1, CFTR) were associated with both the recommended drugs in the guidelines and Meniere's disease related genes. The 2 proteins(CFTR, NOS1) were common across all three groups. Further, GO/KEGG pathway analysis of the collected proteins revealed that the common mechanisms of action between Yijin-tang and the recommended drugs in the guidelines were related to pathways involving immune dysfunction and disturbances in lymphatic fluid homeostasis. In addition, the recommended drugs in the guidelines appeared to act through mechanisms that improve blood flow through vasodilation. Conclusions : Pharmacological network analysis can help to explain the treatment mechanisms of Yijin-tang on Meniere's disease.

Background: Postural hypotension refers to a drop in systolic blood pressure of 20 mmHg or diastolic blood pressure of 10 mmHg or more within three minutes after standing up from lying down. Symptoms of postural hypotension not only include dizziness and blurred vision but also fatigue, cognitive decline, leg weakness, headache, and, in severe cases, fainting. Postural hypotension is a phenomenon that occurs in about 6% of the total population, and in Korea, the number of patients with postural hypotension is continuously increasing. Both pharmacological and non-drug therapies, which are treatment methods for this disease, do not show a satisfactory symptom improvement effect. Case summary: A 65-year-old male patient who visited the hospital complaining of dizziness and paresthesia due to postural hypotension was treated with acupuncture, moxibustion, and herbal medicine. For symptom evaluation, the numeric rating scale (NRS) of each symptom was used, and blood pressure change according to posture was measured. After treatment, the NRSs of dizziness and dysesthesia were decreased, and blood pressure changes according to posture was improved. Conclusion: This case report suggests that Korean medicine treatment, including acupuncture, electro-acupuncture, moxibustion, and herbal medicine, can be an effective treatment for dizziness with postural hypotension.

Objectives : The present study aimed to investigate the pharmacological activity of water and ethanol (EtOH) extracts from Socheongnyong-tang (SCNT) on inflammation and its related disease. Methods : The cells were treated with nontoxic concentrations of water and EtOH extract from SCNT in BEAS-2B, HaCaT, RAW 264.7 and 3T3-L1 cells. These cells were stimulated by tumor necrosis facter (TNF)-${\alpha}$, TNF-${\alpha}$/interferon (IFN)-${\gamma}$, and lipopolysaccharide (LPS), respectively. 3T3-L1 cells were differentiated by insulin. After incubation, supernatant were collected and biological indicator measured by enzyme-linked immunosorbent assay. Results : Our results indicate that the water and EtOH extract of SCNT significantly inhibited the production of regulated on activation normal T-cell expression and secreted (RANTES) by treatment of TNF-${\alpha}$ in BEAS-2B cell, and significantly reduced the production of RANTES and macrophage-derived chemokine increased by treatment of TNF-${\alpha}$/IFN-${\gamma}$ in HaCaT cell. Moreover, those extracts significantly decreased the activity of nitric oxide and prostaglandin $E_2$ in LPS-induced RAW 264.7, and significantly inhibited the increased activity of glycerol-3-phosphate dehydrogenase and expression of leptin induced by differentiation in 3T3-L1 cell. Conclusions : These results indicate that both water and EtOH extract of SCNT has powerful effects on inflammation and its related disease. Therefore, SCNT can be developed as a potential pharmacological agent related various diseases. Although the significant effects were observed in both SCNT water and EtOH extract, the EtOH extract was more effective on most experiments than its water extract. Taken together, these findings indicate that the SCNT EtOH extract may have more potential pharmacological agent.
