  • Purpose: The aim of this study was to evaluate the antimicrobial effect of a newly devised toothbrush with light-emitting diodes (LEDs) on Porphyromonas gingivalis attached to sandblasted and acid-etched titanium surfaces. Methods: The study included a control group, a commercial photodynamic therapy (PDT) group, and 3 test groups (B, BL, and BLE). The disks in the PDT group were placed in methylene blue and then irradiated with a diode laser. The B disks were only brushed, the BL disks were brushed with an LED toothbrush, and the BLE disks were placed into erythrosine and then brushed with an LED toothbrush. After the different treatments, bacteria were detached from the disks and spread on selective agar. The number of viable bacteria and percentage of bacterial reduction were determined from colony counts. Scanning electron microscopy was performed to visualize bacterial alterations. Results: The number of viable bacteria in the BLE group was significantly lower than that in the other groups (P<0.05). Scanning electron microscopy showed that bacterial cell walls were intact in the control and B groups, but changed after commercial PDT and LED exposure. Conclusions: The findings suggest that an LED toothbrush with erythrosine treatment was more effective than a commercial PDT kit in reducing the number of P. gingivalis cells attached to surface-modified titanium in vitro.

  • Hemangioma is benign tumor that represent an fail in development of the vascular system, network or retiform stage. As with hemangioma elsewhere, spontaneous regression may occur. Histologically capillary hemangioma has a diagnostic lobular arrangement of capillaries and almost all of them are located in nasal or oral mucous membranes. But, as we know, there is no report of hemangioma located in the trachea in Korea, so we report a case of tracheal hemangioma which was manifested massive hemoptysis.

  • Background Thin hairs are critical to achieve natural result in female hairline correction surgery. However, there are few studies on the usefulness of hair thinning by intense pulsed light (IPL) after hairline correction surgery in East Asian females. Methods Hair thinning using IPL was performed in 54 women who had complained about thick hairs along the frontal hairline after hairline correction surgery. Patient mean age was 31.2 years old and patients were an average of 2.1 years post-hairline correction surgery. Initial treatment used 10 J, while second and third sessions were conducted with 10 to 15 J according to responsiveness to treatment. Results Mean thickness of individual hairs assessed before the procedure was $78.86{\mu}m$. The mean number of procedures was 1.6 per patient. Forty of 54 subjects (74%) achieved satisfactory hair thinning with only one procedure from 78.01 to $66.14{\mu}m$ after treatment. The measured thickness was $66.43{\mu}m$ at the end of the first year in patients who were satisfied after one procedure. Thirteen cases achieved satisfactory hair thinning after two sessions. Mean thickness was $74.44{\mu}m$ and $67.51{\mu}m$, before and after the second session. One case required a third session with 15J, thinning from 89.00 to $66.50{\mu}m$. Conclusions Hair thinning by IPL is a very useful method to provide a natural look after hairline correction surgery in East Asians, who have naturally thick hair.

  • A 61-year-old male who complained of right upper quadrant pain was referred to the authors for evaluation after his computed tomography suggested biliary adenocarcinoma. The lesion consisted of multiple cysts with papillary mass and peri-ampullay mass. The patient underwent an operation due to a clinical suspicion of biliary cystadenocarcinoma, but the pathology confirmed biliary papillomatosis (BP) after diagnosing intrahepatic papillary neoplasm with high-grade dysplasia and invasive adenocarcinoma with papillary neoplasm from the distal common bile duct to the duodenum. BP is a disease characterized by multiple papillary masses. Its cause has yet to be discovered. It commonly manifests as bile duct dilation but rarely as a ductal cystic change. Under computed tomography or magnetic resonance imaging, both the BP and the cystic neoplasm can show bile duct dilation and a papillary mass, which makes their differential diagnosis difficult. A confirmative diagnosis can be made through a pathologic examination. BP is classified as a benign disease that can become malignant and may recur, though rarely. Its treatment of choice is surgical resection. Laser ablation or photodynamic therapy can be used for unresectable lesions. In the case featured in this paper, biliary papillomatosis was difficult to differentiate from cystic adenocarcinoma due to diffusely scattered multiple large cystic lesions in the liver, and it was histologically confirmed to have become malignant with cystic duct dilation after the operation. This case is reported herein with a literature review.

  • Chemoresistance to cancer therapy is a major obstacle to the effective treatment of human cancers with cisplatin (DDP), but the mechanisms of cisplatin-resistance are not clear. In this study, we established a cisplatin-resistant human ovarian cancer cell line (COC1/DDP) and identified differentially expressed proteins related to cisplatin resistance. The proteomic expression profiles in COC1 before and after DDP treatment were examined using 2-dimensional electrophoresis technology. Differentially expressed proteins were identified using matrix-assisted laser desorption/ ionization time-of-flight mass spectrometry (MALDI-TOF-MS) and high performance liquid chromatography-electrospray tandem MS (NanoUPLC-ESI-MS/MS). 5 protein spots, for cytokeratin 9, keratin 1, deoxyuridine triphosphatase (dUTPase), aarF domain containing kinase 4 (ADCK 4) and cofilin1, were identified to be significantly changed in COC1/DDP compared with its parental cells. The expression of these five proteins was further validated by quantitative PCR and Western blotting, confirming the results of proteomic analysis. Further research on these proteins may help to identify novel resistant biomarkers or reveal the mechanism of cisplatin-resistance in human ovarian cancers.

  • This study was penonned to provide basic data that predict the usefulness of Gastrodiae rhizoma as food materials for oriental medicinal cuisine(YakSun). We measured the changes of regional cerebral blood flow(rCBF) and blood pressure(BP) in rats, following the intravenous injection of Gastrodiae rhizoma water extract The measurement was continually monitored by laser-doppler flowmeter and pressure transducer in anesthetized adult Sprague-Dawley rats for about two to two and half hours through the data acquisition system composed of MacLab and Macintosh computer. The results of this experiment were as follows. Gastrodiae rhizoma increased the changes of rCBF in rats significantly. The rCBF of Gastrodiae rhizoma did not change by pretreated propranolol, atropin, methylene blue and indomethacin. But the rCBF of Gastrodiae rhizoma was increased by pretreated L-NNA. Gastrodiae rhizaoma decreased the changes of BP significantly. The BP of Gastrodiae rhizoma did not change by pretreated propranolol, atropin, methylene blue and indomethacin. But the BP of Gastrodiae rhizoma was decreased by pretreated L-NNA. These results indicated that Gastrodiae rhizoma might increase the rCBF and the BP which related to nitric oxide synthesis. Also these results indicate that Gastrodiae rhizoma can be used as a safe and clinically applicable to diet therapy of cerebral cardiovascular disease.

  • This study aimed to review case reports of Korean medical treatments for sudden sensory neural hearing loss published in Korea from 1980 to 2016. We searched sudden sensory neural hearing loss through 6 major Korean web article search engines and search period was January 1980 to September 2016. Two researchers included studies on sudden hearing loss, clinical studies on korean medical treatments, and excluded in vivo studies, in vitro studies, non-original studies, published abstracts only, and studies not published in Korean or English. 19 articles were included in this study from 63 articles. Only one case report used Korean medical treatment alone. The most tools for treatment were acupunture, herbal medicine, pharmacopunture, moxibustion, cupping treatment and laser therapy. Most acupoints used in the treatment is SI19(聽宮). When patients got treated sooner, recovery rate was better. There was no direct relationship between recovery rate and degree of hearing loss. This study suggests that more research about sudden sensory neural hearing loss is needed in the future.

  • Objectives The purpose of this study is to analyze research trends on Eastern-Western integrative medicine in Korea. Methods We searched the studies on Eastern-Western integrative medicine in 5 Korean web database (NDSL, KoreanTK, KISS, OASIS, DBPIA). 66 research papers we founded. Results 13 papers were published at 2010. The studies on Eastern-Western integrative medicine were mainly published in the Journal of Society of Preventive Korean Medicine. 24 papers were case report, include 7 studies on neurology, 4 studies on each oncology and dermatology, 2 studies on each gastroenterology and ophthalmology and otorhinolaryngology, 1 study on each obstetrics and gynecology and endocrinology and nephrology. In 24 case reports, 7 kinds of Eastern medicine treatment method and 4 kinds of Western medicine treatment method were existed. In case reports, medication (100%), herbal medicine, acupuncture (95.8%), moxibustion (58.3%), cupping, infusion solution (25%), pharmacopuncture (20.8%), physical therapy (12.5%), laser, injection, rehabilitation (8.3%) were used. Conclusions In this study, we analyzed the trends of Eastern-Western integrative medicine in korea from 2010 to 2017. There were various studies about Eastern-Western integrative medicine. In case reports, Eastern-Western integrative medicine tend to concentrated on treatment not diagnosis. Not only treatment but also diagnosis is needed in Eastern-Western integrative medicine studies.

  • Purpose: To evaluate the radial displacement of clinical target volume in the patients with node negative head and neck (H&N) cancer and to quantify the relative positional changes compared to that of normal healthy volunteers. Materials and Methods: Three node-negative H&N cancer patients and five healthy volunteers were enrolled in this study. For setup accuracy, neck thermoplastic masks and laser alignment were used in each of the acquired computed tomography (CT) images. Both groups had total three sequential CT images in every two weeks. The lymph node (LN) level of the neck was delineated based on the Radiation Therapy Oncology Group (RTOG) consensus guideline by one physician. We use the second cervical vertebra body as a reference point to match each CT image set. Each of the sequential CT images and delineated neck LN levels were fused with the primary image, then maximal radial displacement was measured at 1.5 cm intervals from skull base (SB) to caudal margin of LN level V, and the volume differences at each node level were quantified. Results: The mean radial displacements were 2.26 (${\pm}1.03$) mm in the control group and 3.05 (${\pm}1.97$) in the H&N cancer patients. There was a statistically significant difference between the groups in terms of the mean radial displacement (p = 0.03). In addition, the mean radial displacement increased with the distance from SB. As for the mean volume differences, there was no statistical significance between the two groups. Conclusion: This study suggests that a more generous radial margin should be applied to the lower part of the neck LN for better clinical target coverage and dose delivery.

  • Objectives : We investigated the effectiveness and safety of intranasal phototherapy for allergic rhinitis (AR). Methods : We searched 8 electronic databases (PubMed, Cochrane Library, CNKI, CiNii Articles, OASIS, NDSL, KISS, KMbase) to identify randomized controlled trials (RCTs) that reported the use of intranasal phototherapy for AR from their inception until May 30, 2020. Two investigators independently searched, collected, and screened the RCTs. We performed data extraction and evaluation for risk of bias using the Cochrane risk-of-bias tool. Results : This study included 12 RCTs; six studies compared intranasal and sham phototherapy, of which four studies reported a significant inter group difference and two studies reported a significant difference partially. No significant changes in symptoms were observed between the phototherapy and conventional therapy groups. The phototherapy and concurrent acupuncture treatment group showed a significantly higher effectiveness rate compared with the group that received only acupuncture. Both the phototherapy and laser acupuncture group showed significant improvement in the symptom severity scale scores. Six studies reported mild adverse effects, such as dryness and nasal pain in the intranasal phototherapy group; however, no severe adverse effects were reported. Conclusions : This study confirmed the safety and effectiveness of intranasal phototherapy for symptom relief and improved quality of life in patients with AR. However, further studies are needed on this topic in order to demonstrate it clearly.
