  • Ginsing polysaccharide, known to have an immune regulating effect, was administered to 23 randomly selected healthy male subjects with a mean age of 23 years in accordance with an IRB approval. Then, these subjects underwent physico-chemical tests and serum proteome was analyzed from the blood sample taken from these subjects. Analyses of proteome involved image analysis, protein sections and protein identification in sequence after two-dimensional electrophoresis was carried out. During the physico-chemical test, 4 subjects were excluded from the study. In the proteome analysis, identified were 5 spots such as SP40, 40, Cytokeratin 9, hypothetical protein LOC544932, Apolipoprotein E ,similar to Human albumin, which showed differences in the amount of protein expression. In conclusion, changes of 5 proteins were remarkable before and after administration of ginsing polysaccharides. In certain cases, hepatic and renal slight injury occurred. Thus, further clinical study on dosage regimen would be necessary for securing the basis for concentration-dependent effectiveness and safety.

  • Background: Propolis based preparations have a wide range of applications in various specialties of dentistry. The aim of this clinical trial was to test the efficacy of propolis as a mouthwash in the reduction of chemotherapy induced oral mucositis (OM) in a single center. Materials and Methods: In this randomised, controlled study patients undergoing chemotherapy were included consecutively and randomised to an experimental group receiving propolis mouthwash (n = 20) and a control group receiving diluted water (n=20). Oral mucositis, erythema and eating and drink ability were assessed at baseline and after 3 and 7 days using the World Health Organization (WHO) scale and the oral mucositis assessment scale (OMAS). Results: There were significant differences in OM, wound and erythema in propolis group compared to placebo, but no significant difference in eating and drink ability. However, it was interesting that 65% of the patients in the propolis group were completely healed at day 7 of the trial. No significant adverse events were reported by the patients. Conclusions: This study found that oral care with propolis as mouthwash for patients undergoing chemotherapy is an effective intervention to improve oral health. Our findings shouldlencourage health practitioners to apply propolis mouth rinse for the oral care of patients under chemotherapy.

  • Objectives: Aim of present study was designed to investigate the soporific effect of fennel among menopausal women. Methods: The present double-blinded and placebo-controlled trial examined the fennel effect on Pittsburgh Sleep Quality Index (PSQI). Total score and relevant 7 components, including sleep duration, sleep latency, use of sleeping medication, subjective sleep quality, sleep disturbances, daytime dysfunction and habitual sleep efficiency among 50 menopausal women compared to control group within a 12-week follow-up. Results: The patients in both groups reported no certain side effects and all subjects completed the study. The mean actual sleep duration was 5 hours and 66 minutes. Intergroup comparison revealed no statistically significant differences in the mean total PSQI score (P = 0.439), subjective sleep quality (P = 0.826), habitual sleep efficiency (P = 0.127), sleep disturbances (P = 0.130), use of sleeping medication (P = 0.52) and daytime dysfunction (P = 0.439). A tendency toward significant between 2 groups was seen concerning the sleep duration (P = 0.059). Intergroup comparison showed significantly borderline levels (P = 0.059). Conclusions: The treatment of 12 weeks with fennel caused a slight effect that did not reach to significant. These findings should be considered cautiously because of small sample size, short-term follow-up and subjective measure of sleep quality.

  • Background: Alzheimer's disease (AD) is a chronic neurodegenerative disease that causes disorientation, mood swings, problems with language, and difficulty remembering recent events. Acetylcholinesterase inhibitors (AchEIs) and memantine have been used to slow the course of the disease, but they can neither modify its progression nor prevent disease onset. Previous studies have suggested that Kami-guibi-tang (KGT) could be beneficial for supporting cognitive function in AD patients, but few clinical trials have been published. This pilot study aimed to evaluate the effect of KGT in improving cognitive function in AD patients. Methods: The study will be a randomized, placebo-controlled, double-blind, single-center trial conducted using subjects diagnosed with mild AD by neurologists. Study subjects will be randomly assigned to either a treatment or control group. The treatment group will receive KGT granules for 24 weeks, while the control group will receive placebo granules. AchEI administration will be maintained in both groups during the entirety of the study. Subjects will be assessed using the following exams: the Seoul Neuropsychologic Screening Battery (SNSB) for cognitive function; brain magnetic resonance imaging (MRI) for brain metabolite, neurotransmitter, and cerebral blood flow (CBF) measurements; the Korean version of Quality of Life-Alzheimer's Disease (KQol-AD) for quality of life; the Caregiver-Administered Neuropsychiatric Inventory (CGA-NPI) for neurobehavioral symptoms; blood tests for amyloid and tau proteins and general blood parameters; and electrocardiography (ECG) before and after taking the medication. Discussion: Our findings will provide insight into the feasibility of large-scale trials to consolidate evidence for the efficacy of KGT for dementia treatment.

  • Background and Purpose: The efficacy and safety of GV1001 have been demonstrated in patients with moderate-to-severe Alzheimer's disease (AD). In this study, we aimed to further demonstrate the effectiveness of GV1001 using subscales of the Severe Impairment Battery (SIB), which is a validated measure to assess cognitive function in patients with moderate-to-severe AD. Methods: We performed a post hoc analysis of data from a 6 month, multicenter, phase 2, randomized, double-blind, placebo-controlled trial with GV1001 (ClinicalTrials.gov, NCT03184467). Patients were randomized to receive either GV1001 or a placebo for 24 weeks. In the current study, nine subscales of SIB-social interaction, memory, orientation, language, attention, praxis, visuospatial ability, construction, and orientation to name-were compared between the treatment (GV1001 1.12 mg) and placebo groups at weeks 12 and 24. The safety endpoints for these patients were also determined based on adverse events. Results: In addition to the considerable beneficial effect of GV1001 on the SIB total score, GV1001 1.12 mg showed the most significant effect on language function at 24 weeks compared to placebo in both the full analysis set (FAS) and per-protocol set (PPS) (p=0.017 and p=0.011, respectively). The rate of adverse events did not differ significantly between the 2 groups. Conclusions: Patients with moderate-to-severe AD receiving GV1001 had greater language benefits than those receiving placebo, as measured using the SIB language subscale.

  • Background : Mahuang (Ephedrae Herba, Ephedra sinica $S_{TAPE}$) has been widely used to treat respiratory disease in Asian over the past thousand years. The main ingredient of Mahuang is ephedrine, whose affects on the autonomic nervous system induce some adverse effects like vasoconstriction, hypertension, tachycardia, miosis, insomnia, dizziness, headache, etc. Although there were lots of reports about adverse effects of Mahuang, there were no clinical studies which evaluated the adverse effects of Mahuang on the autonomic nervous system by objective numerical value in the past decade. Objectives : The purpose of this report was to provide an objective assessment of state-trait anxiety that is caused by Mahuang, and to identify anxiety of Mahuang according to different Sasang constitution classifications. Methods : The study design was a double-blind randomized placebo-controlled trial. The subjects of this study were 79 adults aged between 20 to 40 who agreed to participate. Because 8 adults dropped out, a total of 71 subjects entered the study. They were allocated through randomization to a Mahuang group (N=50) and placebo group (N=21). Each group took three opaque capsules (every opaque capsule containing 2g of Mahuang or none) twice a day. To compare the state and trait anxiety before and after taking Mahuang, we checked the anxiety by using STAI-KYZ. Results : The following results were obtained. Short-term administration of Mahuang significantly increased state-anxiety, but in the placebo group, there were no significant changes in state-anxiety. In the Mahuang group except females, there was more significant increase in state-anxiety of Soeumin than Soyangin and Taeumin in the 2nd measurement. Conclusion : It is suggested that the ingestion of Mahuang can increase sympathetic activity and induce anxiety. There was a significant difference among Sasang constitution classification. Especially, the response is stronger in Soeumin than other constitutions. If we use Mahuang according to the Sasang constitution classification in clinic, we could not only minimize the anxiety but maximize the potential curative value.
