Purpose: This systematic review and meta-analysis was conducted to assess the effects of glycine powder air-polishing (GPAP) in patients during supportive periodontal therapy (SPT) compared to hand instrumentation and ultrasonic scaling. Methods: The authors searched for randomized clinical trials in 8 electronic databases for relevant studies through November 15, 2019. The eligibility criteria were as follows: population, patients with chronic periodontitis undergoing SPT; intervention and comparison, patients treated by GPAP with a standard/nozzle type jet or mechanical instrumentation; and outcomes, bleeding on probing (BOP), patient discomfort/pain (assessed by a visual analogue scale [VAS]), probing depth (PD), gingival recession (Rec), plaque index (PI), clinical attachment level (CAL), gingival epithelium score, and subgingival bacteria count. After extracting the data and assessing the risk of bias, the authors performed the meta-analysis. Results: In total, 17 studies were included in this study. The difference of means for BOP in patients who received GPAP was lower (difference of means: -8.02%; 95% confidence interval [CI], -12.10% to -3.95%; P<0.00001; I2=10%) than that in patients treated with hand instrumentation. The results of patient discomfort/pain measured by a VAS (difference of means: -1.48, 95% CI, -1.90 to -1.06; P<0.001; I2=83%) indicated that treatment with GPAP might be less painful than ultrasonic scaling. The results of PD, Rec, PI, and CAL showed that GPAP had no advantage over hand instrumentation or ultrasonic scaling. Conclusions: The findings of this study suggest that GPAP may alleviate gingival inflammation more effectively and be less painful than traditional methods, which makes it a promising alternative for dental clinical use. With regards to PD, Rec, PI, and CAL, there was insufficient evidence to support a difference among GPAP, hand instrumentation, and ultrasonic scaling. Higher-quality studies are still needed to assess the effects of GPAP.

To evaluate the antitumor activity and antimetastatic effects of Kamigumgusingihwan(KGSH) studies have ken done. The results were obtained as follows: 1. KGSH extracts exhibited a weak cytotoxicity against A549, SK-OV-3, B16-F10, and SK-MEL-2 cell lines. But exhibited potent cytotoxicity against P388 cell line in a dose-dependent manner. 2. The concentration inhibiting adhesion of A549, to complex extracellular matrix up to below 30% of control was recognized at $10^{-3}g/ml$ of KGSH 3. KGSH extracts showed a weak inhibitoty effect on DNA topo-isomerase I from calf thymus. 4. The T/C% was 137% in KGSH treated group in S-180 bearing ICR mice. 5. In pulmonary colonization assay, a number of colonies in the lungs were decreased significantly in KGSH treated group as compared with control group. 6. In hematological changes in B16-BL6 injected C57BL/6, numbers of WBC were decreased insignificantly in KGSH treated groups, and also those of platelet were increased insignificantly in KGSH treated groups as compared with control. 7. In CAM assay, KGSH extracts inhibited angiogenesis at $15{\mu}g/egg $concentration significantly as compared with control. Taken together these results, it is strongly demonstrated that KGSH significantly suppressed tumor metastasis by blocking cell adhesion to extracellular matrix. Therefore, KGSH is expected to be clinically a potent antimetastatic drug for the prevention and treatment of cancer.
Background : It was not enough to apply three kinds of syndrome differentiation in our oriental medical textbook to tremor's treatment according to reports of Korea and traditional medical textbook of China. Objective : To investigate syndrome differentiations by types of diseases related to tremor through Chinese journals review and to suggest adding possible syndrome differentiations. Methods : Literature search was performed using China Academic Journal (CAJ), the search engine of China National Knowledge Infrastructure (CNKI) from January 1994 to December 2009. Searching key words were Chinese characters in combination meaning tremor, paralysis agitans, and syndrome differentiation. We included all types of articles that explained or referred to definite syndrome differentiations. The symptoms and oriental medications by syndrome differentiation in selected articles were extracted and summarized. Results : 56 Chinese journals were ultimately selected. 37 kinds of syndrome differentiations about tremor were investigated, which included dual deficiency of qi and blood (氣血兩虛) quoted 31 times, liver-kidney yin deficiency (肝腎陰虧) 23 times, liver-kidney deficiency (肝腎不足) 21 times, and phlegm-heat stirring wind (痰熱動風) 20 times. 37 kinds of syndrome differentiation could by group into eight types, such as liver-kidney yin deficiency (肝腎陰虧), dual deficiency of qi and blood (氣血兩虛), phlegm-heat stirring wind (痰熱動風), heart deficiency and spirit weakness (心虛神弱), blood stasis due to qi stagnation (氣滯血瘀), sea of marrow deficiency (髓海不足), liver qi depression (肝氣鬱結), and liver yang transforming into wind (肝陽化風). Conclusion : We suggest that the syndrome differentiations of tremor, such as heart deficiency and spirit weakness (心虛神弱), blood stasis due to qi stagnation (氣滯血瘀), sea of marrow deficiency (髓海不足), liver qi depression (肝氣鬱結), and liver yang transforming into wind (肝陽化風), can be added to liver-kidney deficiency (肝腎不足), dual deficiency of qi and blood (氣血兩虛), and phlegm-heat stirring wind (痰熱動風) of the textbook. Further systematic research will be needed on them.

Objectives: Infection involving the orbit, zygomatic space, lateral pharyngeal space, or hemifacial and oral floor phlegmon is referred to as cervicofacial infection (CFI). When diagnosis and/or adequate treatment are delayed, these infections can be life-threatening. Most cases are the result of odontogenic infections. We highlight our experiences in the management of this life-threatening condition. Materials and Methods: This was a retrospective study of patients who presented with CFI from December 2005 to June 2012 at the Oral and Maxillofacial Surgery Clinic or the Accident and Emergency Unit of Ahmadu Bello University Teaching Hospital (Zaria, Nigeria). The medical records of all patients who presented with either localized or diffuse infection of the maxillofacial soft tissue spaces were retrospectively collected. Data collected was analyzed using SPSS version 13.0 and are expressed as descriptive and inferential statistics. Results: Of the 77 patients, 49 patients (63.6%) were males, a male to female ratio of 1:7.5. The ages ranged from two years to 75 years with a mean of $35.0{\pm}19.3$ years, although most patients were older than 40 years. The duration of symptoms prior to presentation ranged from 6 to 60 days, with a mean of $11.0{\pm}9.4$ days. More than 90% of the patients presented to the clinic within the first 10 days. The most commonly involved anatomical space was the submandibular space (n=29, 37.7%), followed by hemifacial space (n=22, 28.6%) and buccal space (n=7, 9.1%). Ludwig angina accounted for about 7.8% of the cases. Conclusion: CFI most commonly involves the submandibular space, typically affects individuals with a low level of education, and is influenced by traditional medical practices. Despite improved health care delivery, CFI remains a significant problem in developing countries.
Sopungsungi-won has been used as a traditional medicine for diabetes and it has been proved to be a potential remedy for type 2 diabetes mellitus. We previously reported that water extract of Sopungsungi-won exhibits anti-diabetic effects both in vivo and in vitro experiments. In the present study, we have chosen to examined anti-apoptotic effect of Rheum undulatum, which is the main component of Sopungsungi-won, on pancreatic ${\beta}-cells$, HIT-T15, against hydrogen peroxide $(H_2O_2)$. oxidative stress. To investigate the anti-apoptotic effect of Rheum undulatum water extract (RUWE) against $H_2O_2-induced$ apoptosis in pancreatic ${\beta}-cell$ line of hamster, HIT-T15, MTT assay, DAPI staining, TUNEL assay, RT-PCR and caspase-3 enzyme assay were performed. The morphological analysis demonstrated that cells treated with $H_2O_2$ exhibited classical apoptotic features, while such changes was reduced in cells pre-treated with RUWE. In addition, RUWE pre-treated cells prior to $H_2O_2$ treatment induced increase of levels of bcl-2 expression and decrease of caspase-3 enzyme activity compared to cells treated with $H_2O_2$ only. These results provide the possibility of usage of RU in patients with progressively deteriorated diabetes.

Ginseng is a traditional herbal medicine used for prevention and treatment of various diseases as a tonic. Recent scientific cohort studies on life prolongation with ginseng consumption support this record, as those who consumed ginseng for more than 5 years had reduced mortality and cognitive decline compared to those who did not. Clinical studies have also shown that acute or long-term intake of ginseng total extract improves acute working memory performance or cognitive function in healthy individuals and those with subjective memory impairment (SMI), mild cognitive impairment (MCI), or early Alzheimer's disease (AD) dementia who are taking AD medication(s). Ginseng contains various components ranging from classical ginsenosides and polysaccharides to more recently described gintonin. However, it is unclear which ginseng component(s) might be the main candidate that contribute to memory or cognitive improvements or prevent cognitive decline in older individuals. This review describes recent clinical contributors to ginseng components in clinical tests and introduces emerging evidence that ginseng components could be novel candidates for cognitive improvement in older individuals, as ginseng components improve SMI cognition and exhibits add-on effects when coadministered with early AD dementia drugs. The mechanism behind the beneficial effects of ginseng components and how it improves cognition are presented. Additionally, this review shows how ginseng components can contribute to SMI, MCI, or early AD dementia when used as a supplementary food and/or medicine, and proposes a novel combination therapy of current AD medicines with ginseng component(s).
Objectives : The purpose of this study was to report the clinical characteristics of glossodynia patients and effects of traditional Korean treatment on glossodynia and to gather data in order to carry out future study. Methods : We surveyed 40 glossodynia patients visiting the Department of Korean Internal Medicine of Stroke and Neurological Disorders Center, Kyung Hee University Hospital at Gangdong and analyzed their glossodynia questionnaires, examination results, and progression of symptoms. Results : In Glossodynia patients the average age was 62.4 years old. Glossodynia was more prevalent in females than males (5.67:1). Red tongue color, white fur, and fissured tongue were observed most often. The average glossodynia duration was 36.1 months and the average glossodynia degree was VAS 5.6. The most commonly appearing symptom was burning sense, and dryness of tongue. In Korean medicine diagnosis, Yin, deficiency, Tae-eum was most commonly diagnosed. In herbal medicine, Gamichungsim-tang was the most frequently prescribed. In laboratory tests, zinc deficiency was the most common result. In heart rate variability (HRV), average SDNN was 34.03 and average LF/HF ratio was 2.11. Of 40 patients, 23 completed treatment and their pain was relieved from average VAS 5.52 to VAS 3.63. Pre-and post-treatment results showed a significant difference. The average duration of treatment was 34.91 days. Conclusions : The results of this study suggest that Korean medical approach and treatment for glossodynia could be effective. Further study should be conducted for more valuable information.

Background: Astilbe chinensis (Maxim.) Franch. Et Savat. is a plant belonging to Saxifragaceae family and contains various active ingredients including astilbin and bergenin. It has been used as a traditional Korean medicine to improve fever, pain, and cough. Recently, a number of Korean medical resources have been studied for cancer and inflammation treatment, but A. chinensis (Maxim.) Franch. Et Savat. has not yet been investigated. Consequently, this study investigated the inhibitory effect of ethanol extracts from A. chinensis (Maxim.) Franch. Et Savat. (ARE) on oxidative stress and colorectal cancer using RAW264.7 and the human colorectal cancer cell line HCT-116. Methods and Results: In total, $500{\mu}g/m{\ell}$ ARE reduced cell viability by $38.96{\pm}1.32%$, and increased caspase-3 activity by $133.08{\pm}3.41%$ in HCT-116 cells. Moreover, TUNEL signaling and the early apoptosis ratio ($34.56{\pm}1.67%$) increased by $500{\mu}g/m{\ell}$ ARE treatment. $H_2O_2$-induced oxidative stress and cell death were diminished by $500{\mu}g/m{\ell}$ ARE treatment through decreasing ROS (reactive oxygen species). Conclusions: The inhibitory effects of ARE against human colorectal cancer cells is mediated by apoptosis and caspase-3 activation, and $H_2O_2$-induced ROS generation and cell death are decreased by ARE treatment in RAW264.7 cells. However, further study is required to explore how ARE treatment is involved in the signaling pathway to decrease ROS.
Objectives: Advancements in nanotechnology have led to nanoparticle (NP) use in various fields of medicine. Although the potential of NPs is promising, the lack of documented evidence on the toxicological effects of NPs is concerning. A few studies have documented that homeopathy uses NPs. Unfortunately, very few sound scientific studies have explored the toxic effects of homeopathic drugs. Citing this lack of high-quality scientific evidence, regulatory agencies have been reluctant to endorse homeopathic treatment as an alternative or adjunct treatment. This study aimed to enhance our insight into the impact of commercially-available homeopathic drugs, to study the presence of NPs in those drugs and any deleterious effects they might have, and to determine the distribution pattern of NPs in zebrafish embryos (Danio rerio). Methods: Homeopathic dilutions were studied using high-resolution transmission electron microscopy with selected area electron diffraction (SAED). For the toxicity assessment on Zebrafish, embryos were exposed to a test solution from 4 - 6 hours post-fertilization, and embryos/larvae were assessed up to 5 days post-fertilization (dpf ) for viability and morphology. Toxicity was recorded in terms of mortality, hatching delay, phenotypic defects and metal accumulation. Around 5 dpf was found to be the optimum developmental stage for evaluation. Results: The present study aimed to conclusively prove the presence of NPs in all high dilutions of homeopathic drugs. Embryonic zebrafish were exposed to three homeopathic drugs with two potencies (30CH, 200CH) during early embryogenesis. The resulting morphological and cellular responses were observed. Exposure to these potencies produced no visibly significant malformations, pericardial edema, and mortality and no necrotic and apoptotic cellular death. Conclusion: Our findings clearly demonstrate that no toxic effects were observed for these three homeopathic drugs at the potencies and exposure times used in this study. The embryonic zebrafish model is recommended as a well-established method for rapidly assessing the toxicity of homeopathic drugs.
