Objective : This study's purpose was to review the clinical studies of Galgeun-tang. Method : We searched papers about Galgeun-tang using KISS, RISS, OASIS, PUBMED and J-stage. The key words we used were "Galgeuntang", "Kakkonto", "Ge gen tang", and "Pueraria Decoction". Papers not matched with inclusion criteria were excluded. Results : Until today, there have been 223 studies on Galgeun-tang. Of these, 25 studies were classified as clinical research papers. There were 4 cases of fever, 5 cases of inflammation on respiratory system, 3 cases of head, neck and shoulder disorder, 2 cases of diarrhea, 6 cases of pharmacokinetics and interaction, 5 cases of side effect. Conclusion : It can be seen that Galgeun-tang has established the basis for application to the purpose of treating fever (common cold, influenza), inflammation on respiratory system (nasal obstruction, maxillary sinus retention cyst, mucoid pseudomonas aeruginosa chronic lower respiratory tract infection), head, neck and shoulder disorder (temporomandibular disorders, shoulder stiffness, tetanus), and diarrhea. On the other hand, considering 4 cases of side effect on drug eruption, caution should be exercised when observing the progress of the patient taking Galgeun-tang.

Background: Sevoflurane, a rotatively new inhalational anesthetic. has non-pungent odor and is less reluctant to pediatric patients. The purpose of this study is to examine the feasibility of sevoflurane in inhalational sedation instead of the nitrous oxide for short and simple dental treatments in pediatric patients. Patients and Methods: Fifteen healthy children, whose dental treatment was abandoned due to their little or no cooperation, were selected with their caregivers' written permission. Deep sedation was induced and maintained with oxygen and 1-5% sevoflufane via specially designed nasal mask. Blood pressure, heart rate, oxygen saturation, and electrocardiogram were monitored at 3-nin interval. A dental anesthesiologist, who was independent of dental treatments, was wholly responsible for the sedation procedure. Post-sedation complications and operator's and caregiver's acceptability of this type of inhalational sedation were also investigated. Results: The systolic and diastolic blood pressure, heart rate, and oxygen saturation was significantly depressed during the deep sedation using sevoflurane (P < 0.05). No severe post-sedation complications were found, however, bradycardia was reported in 3 patients. Almost all the operators and caregivers answered that they would adapt this sedation procedure again if possible. Conclusion: In this study, inhalational deep sedation using sevoflurane for dental treatments was found to be very useful. Furthermore, the application of sevoflurane to conscious sedation for pediatric and adult dental patients should be added.

Background: Over the years, pine pollens have been excluded as an allergen due to its relatively large size, low protein content, and waxy hydrophobic layer, despite their abundance. However, recent studies suggest the possibilities of pine pollens being allergens, and it has been reported that allergy symptoms were highly prevalent in areas with considerably large pine forests and high possibility of exposure to the pollen. Therefore, we conducted a comparative analysis of the allergenicities of the pollens from the dominant species of Korean pines, red pine (Pinus densiflora), black pine (Pinus thunbergii), and pitch pine (Pinus rigida), in mice. Methods: The protein composition of the pollens from the three pine species was compared via sodium dodecyl sulfate polyacrylamide gel electrophoresis (SDS-PAGE). The pine pollens and proteins extracted from the pollens were introduced to BALB/c mice by nasal inhalation and application to exposed skin and the IgE produced by the mice were extracted from blood and analyzed via ELISA. Results: SDS-PAGE showed differing protein compositions of the pollens of the three pine species. Analysis of blood IgE compositions showed a similar amount of IgE produced when pollens were applied to skin. In contrast, when mice inhaled the pollens, P. densiflora was shown to induce significantly more IgE production than those of the other two species. Conclusions: The experimental results demonstrate that the pollens of all three South Korean pine species induce IgE production, and this production was more pronounced when the pollens were inhaled than when they were applied to the skin. Of the three species, the pollen of P. densiflora was found to induce the highest level of IgE production.

Purpose: The forehead flap is the workhorse in nasal reconstruction, which provides a similar skin color, texture, structure, and reliability. There are some disadvantages, including donor site morbidities, 2- or 3-stage operations, and postoperative management after initial flap transfer. Furthermore, there has been little attention to the exposed raw surface wound, after the first stage of an operation. This article describes the authors' modification to overcome this problem, using artificial collagen membrane. Methods: An Artificial collagen membrane is composed of an outer silicone membrane and an inner collagen layer. After a forehead flap elevation, the expected raw surface was covered by an artificial collagen membrane with 5-0 nylon suture. A simple dressing, which had been applied to the site, was changed every 2 or 3 days in an outpatient unit. At 3 weeks postprocedure, a second stage operation was performed. Results: With biosynthetic protection of the raw surface, there were no wound problems, such as infection or flap loss. Thus, the patient was satisfied due to an effortless management of the wound and a reduction in pain. Conclusion: The application of an artificial collagen membrane to the raw under-surface of the flap could be a comfortable and a protective choice for this procedure.

Objectives : This study aimed to assess the scientific evidence for the use of Hwanglyeonhaedok-tang, a traditional herbal formula, in the treatment of rhinitis, and prepare the basis for the investigational new drug application by analyzing the experimental studies. Methods : Ten electronic databases were searched up to December, 2016 without language limitation. Experimental studies on the anti-inflammatory and anti-allergic effects of Hwanglyeonhaedok-tang against rhinitis were included. We extracted data about study design, characteristics of intervention, outcomes, and pharmacological effects from the included studies and summarized them. Results : Eight hundred and thirty-three potentially relevant studies were identified, of which 18 experimental studies met our inclusion criteria. Of 18 included studies, 5 had conducted cell viability test, and all studies had reported that Hwanglyeonhaedok-tang was non-cytotoxic. Hwanglyeonhaedok-tang exhibits anti-inflammatory effect by regulating the inflammation-related cytokines including nitric oxide(NO), prostaglandin $E_2(PGE_2)$, interleukin-6(IL-6), and tumor necrosis $factor-{\alpha}(TNF-{\alpha})$ in vitro and in vivo. Hwanglyeonhaedok-tang exhibits anti-allergic effect by suppressing eosinophil, and histamine levels. Hwanglyeonhaedok-tang helps in the recovery of nasal mucous membrane by supressing goblet cells, heat shock protein 70, and substance P. Conclusions : This study suggests that Hwanglyeonhaedok-tang has the potential to be developed as therapeutic agent for rhinitis. Further experimental and clinical studies needed to be performed to prove the safety and efficacy.

Objectives : To analyze symptoms of olfactory dysfunction caused by COVID-19 from a Korean Medical Perspective. Methods : Previous studies dealing with olfactory dysfunction accompanying COVID-19 were studied and analyzed for general characterization. Physiology and pathology of olfactory functions within the classical texts of Korean Medicine were collected and analyzed, through which symptoms of olfactory dysfunction in COVID-19 were examined. Results : Olfactory dysfunction manifested in high ratios in the early stages of confirmed COVID-19 cases, at times independent of other nasal symptoms such as blockage or discharge. There was a high chance of loss of taste being accompanied, while mental problems such as a tendency to have difficulty concentrating were present as well. In most cases, recovery took one to two weeks. From a Korean Medical perspective, physiology of olfactory function is closely linked to the Lungs, Ancetral Qi[宗氣], and the Heart, while its dysfunction could be explained by pathological factors such as Wind-Cold, Fire stagnation, Qi deficiency, Wind stroke, etc. Conclusions : In the context of external contraction disease[外感病], olfactory dysfunction could be caused by problems in the Lungs and Stomach that are responsible for breathing, or the Heart which is involved in recognizing and differentiating scent. General characteristics of COVID-19 imply it to be closely related to the Heart. In clinical application, overall symptoms need to be considered in diagnosis and treatment planning, after which further approaches could made to determine the problem to be of the Lung and Stomach, or of the Heart.

Objectives This study aims to establish a protocol for a systematic review to evaluate the effectiveness and safety of manual therapy (MT) for obstructive sleep apnea (OSA). Methods We will conduct a search for relevant randomized controlled trials using seven databases, including MEDLINE/PubMed, Embase, and the Cochrane Central Register of Controlled Trials. The study includes patients with OSA treated with MT. Comparators include all other treatments excluding MT. The primary outcome is the apnea-hypopnea index; secondary outcomes include mean peripheral oxygen saturation, snoring index, quality of sleep, quality of life, peak nasal inspiratory flow, and adverse events. Results Two independent researchers will select studies based on inclusion criteria and extract necessary data. Risk of bias (RoB) will be assessed using the Cochrane RoB 2.0 tool. Meta-analysis will be conducted if there are two or more studies with the same outcome measure; otherwise, a qualitative analysis will be performed. Subgroup analysis will be conducted based on the type of MT, and evidence certainty will be evaluated using the Grading of Recommendations Assessment, Development, and Evaluation approach. Conclusions This study will evaluate the effect of MT on OSA. By systematically reviewing various MTs, it aims to refine application methods in clinical practice and provide a foundation for future research.

Objectives: Obstructive sleep apnea syndrome(OSAS) is known to be associated with the changes of autonomic nervous system (ANS). Nasal continuous positive airway pressure(nCPAP) treatment was found to correct abnormal ANS changes in OSAS but it remains to be further clarified. We aimed to assess the effects of nCPAP on ANS manifested on electrocardiogram, using spectrum analysis in the subjects with OSAS. Methods: Digital polysomnography was performed in 18 patients with OSAS(mean age $43.7{\pm}16.6$ years ; 17 males, 1 female ; mean respiratory disturbance index (RDI) $48.6{\pm}20.9$) for one baseline and another CPAP nights. From each night, 300 continuous beats of ECGs without artifact were chosen from both stage 2 sleep and REM sleep and they were used for power spectrum analysis. We compared between baseline and CPAP nights the heart rate variability including VLF(very low frequency power), LF (low frequency power), HF(high frequency power), R-R means, R-R variance, and LF/HF ratio, using Wilcoxon signed ranks test. Results: In all patients, nCPAP proved to be effective in relieving apneas and snoring. During nCPAP night compared with baseline night, decreases in VLF(p<0.05), LF(p<0.01), and R-R variance(p<0.05) were found in stage 2 sleep, and decreased LF(p<0.05) was found in REM sleep. No significant differences in each sleep stage were found in other variables between the two nights. Conclusion: Our findings suggest that OSAS increases the activity of sympathetic nervous system and nCPAP application effectively decreases the activity. And nCPAP does not appear to influence the parasympathetic nervous activity in OSAS.

Objectives: Nasal continuous positive airway pressure (nCPAP) is the treatment of choice and has been shown to reduce the frequency of nocturnal respiratory events, improve sleep architecture, and decrease daytime sleepiness in patients with obstructive sleep apnea syndrome (OSAS). However, little is known about the compliance of nCPAP treatment in Korea. Our objective was to look into the nCPAP compliance and examine the factors influencing it. Methods: We reviewed the records of one hundred and twenty consecutive patients with OSAS referred for nocturnal polysomnography with nCPAP pressure titration during the period of January 1995 through April 1999 to the Seoul National University Hospital. We performed a telephone interview and obtained data from eighty-three patients. Results: In sixty patients who had accepted nCPAP treatment, twenty-six patients (43.3%) were still using nCPAP device, while thirty-four patients (56.7%) stopped using it. Fifteen patients (25%) were using nCPAP device everyday. In thirty-four patients who discontinued nCPAP use, twenty-five patients (73.5%) did within the first three months, and thirty-one (91.2%) within the first year. Significant predictor of long-term nCPAP use was the presence of subjective daytime sleepiness before nCPAP application. Conclusions: Long-term compliance with nCPAP treatment appears to be associated with the presence of subjective daytime sleepiness before nCPAP application. Long-term compliance with nCPAP may be mostly predicted from the usage pattern within the first three months of use.

The clinical application of constitutional Diagnosis is the most important part of Sasang constitutional medicine. It has been studied in various way. The study of morphologic characteristics on the head and face has been identified but didn't considered the Variations of age and sex. For the statistic analysis of the correlation between the sasang constitution and the shape of the face, the head-facial part of 182 cases(the group of throughout the age) and 69 cases(the group of age 30 to 40) were measured by Martin's measurement and analysis of a) the measurement value of height and the component ratio from the Gnathion to each part of face by constitution. b) the measurement value of depth and the component ratio from T-projected to each part of the face by constitution. c) the measurement value of breadth and component ratio between each parts of the facial breadth by constitution. d) the characteristics on each part of face by constitution. e) the result of discriminant analysis about the constitution Authors obtained the results from the study as follows: 1. Taeum-In group is characterized by the value of variables had a tendency to maximum value in throughout the age, the charateristics that the total group show is the shape of face is wide shape in horizontally and flat, the nasal breadth is wider than other constitutions, the lips is narrower than Soyang-In in horizontally and thick shape in vertically, and the biogonial breadth is more developed than other constitutions, so lower face is developed. The charateristics that only the age of 30 40 group show is that the lips is thicker than Soeum-IN. The projection of inter-eyebrows is more projected than Soyang-IN. 2. Soeum-IN group is characterized by the value of variables had a tendency to minimum value in throughout the age. The characteristics that the total group show is the lips is thiner than other constitutions, the breadth of eyes is wider than other constitutions, the difference between sellion and nasal breadth is to be little. The charateristics that only the age of 30 40 group show is that the ratio of upper face in physiognomic face is lager than Soyang-IN. 3. The total age group of Soyang-In is characterized by the shape of face is long in vertically and narrow in horizontally, the total eyebrow breadth and lips and philtrun is wider than other constitutions. The charateristics that only the age of 30 40 group is characterized by the projection of sellion is more projected than Taeum-IN. 4. The values which showed significance in both age group V76, V52, V54, V55, V57, V59, V64, V65, V67, V88, V89, V148, V150, V151, V155, V160, V161, V28, V50, V99, V102, V167, V169, V173, V175, V177, V181 are 27 in all. 5.
