Successful middle ear surgery requires the availability of al safe, effective bonding material. Side effect caused by synthetic materials have led to the use of biologic adhesive. However, they carry the risk of transmission of infectious diseases if they are prepared from pooled human blood. The adhesive strength of ammonium sulfate fibrin adhesive produce an adhesive strength that is half that of the homologous commercial product. It is, however, good enough for use in several otolaryngological operations, tympanoplasty, facial nerve repair, reconstruction of ossicles, reconstruction of posterior wall of ear canal and obliteration of frontal sinus and mastoid antrum using bone dust.

Glutaredoxin 1 (GLRX1) has been recognized as an important regulator of redox signaling. Although GLRX1 plays an essential role in cell survival as an antioxidant protein, the function of GLRX1 protein in inflammatory response is still under investigation. Therefore, we wanted to know whether transduced PEP-1-GLRX1 protein inhibits lipopolysaccharide (LPS)- and 12-O-tetradecanoyl phorbol-13-acetate (TPA)-induced inflammation. In LPS-exposed Raw 264.7 cells, PEP-1-GLRX1 inhibited cyclooxygenase-2 (COX-2), inducible nitric oxide synthase (iNOS), activation of mitogen activated protein kinases (MAPKs) and nuclear factor-kappaB (NF-κB) expression levels. In a TPA-induced mouse-ear edema model, topically applied PEP-1-GLRX1 transduced into ear tissues and significantly ameliorated ear edema. Our data reveal that PEP-1-GLRX1 attenuates inflammation in vitro and in vivo, suggesting that PEP-1-GLRX1 may be a potential therapeutic protein for inflammatory diseases.

Objectives: Hundreds of thousands of call center workers are wearing an acoustic device for their businesses, such as telemarketing and customer counseling, and the number of the workers are increasing sharply. Because call center workers always talk to dozens of customers over the headset, they would be placed under the state of a higher risk with their hearing ability. The purpose of this study is to investigate factors that affect the hearing thresholds for the call center workers. Methods: This study investigated hearing losses of 101 workers of 5 call centers in Korea by executing puretone audiometry and self-administered questionnaires. A cross table analysis was processed to compare gender differences between male and female. Male and female hearing thresholds were compared with the Students' t-test, and one-way ANOVA was conducted to observe the difference between non-occupational and occupational characteristics in 2, 3, 4, 6, and 8 kHz hearing thresholds for the female workers. Additionally, multiple regression analysis was conducted to find the factors that affect the 4 kHz hearing thresholds. Results and Conclusions: Male hearing thresholds were higher than those of female except for 8 kHz. In the group having an ear related disease, hearing threshold of male left ear was highly affected rather than that of female in 4 kHz. There were significant differences in the variables of alcohol drinking (2 kHz) and headset volume (8 kHz) in both ears. While this study does not show any significant factors that affect the hearing thresholds in the occupational characteristics, the gender and the previous ear related diseases, non-occupational characteristics, were found as the factors in 4 kHz. It is suggested that the more detailed survey be performed to identify the occupational factors that affect the hearing thresholds in the call center workers based on the result derived from this study.

This study was investigated the anti-allergic effect of SJSBT on DNCB induced atopic dermatitis in NC/Nga mice. We summerized as the follow. SJSBT significantly decreased the clinical manifestations of atopic dermatitis including itching, dryness, edema, hemorrhage, and lichenification in dose dependent manner. SJSBT markedly suppressed invasion and edema of leukocytes and mast cell in dorsal skin and ear tissue. SJSBT significantly reduced the number of CD11b+/Gr-1 cell compared with positive control, but it had no affect the number of CD3+ and CCR3+/CD3+ cell. SJSBT markedly suppressed the expression of cytokine and chemokine such as IL-6, $TNF-{\alpha}$, eotaxin and CCR3 compared with positive control group. SJSBT significantly decreased the invasion of CD4+ and CCR3+ cell in ear and dorsal skin tissue compared with positive control group by using immunohistochemical staining. Taken together, these findings suggested that SJSBT has an anti-allergic activity and this might be useful for the clinical application to treat allergic diseases such as atopic dermatitis.

Dizziness is one of common diseases clinically, it is defined as a hallucination or an illusion of motion that causes sensation disorder of circumstance, and described as circulatory. rotatory leaning. shaking sensation. In particular, benign paroximal positional vertigo(BPPV) is one of peripheral vertigo, it causes dizziness due to debris which has collected within a part of the inner ear. Chemically, debris are small crystals of calcium carbonate. They are derived from structures in the ear called 'otoliths' that have been damaged by head injury, infection, or other disorder of the inner ear, or degenerated because of advanced age. The symptoms of BPPV include dizziness or vertigo, lightheadedness, imbalance, and nausea, Activities which bring on symptoms will vary in each person, but symptom are almost always precipitated by a position change of the head or body. As for treatment of vertigo, it is differentiated as excess in the upper and deficiency in the lower(上實下虛) and treated in oriental medicine and are used to stability. antihistaminics . anticolinergics . vestibule control drug of GABA system in western medicine. Moreover, Dix-hallpike maneuver is applicated in diagnosis and treatment of BPPV patients. A case of dizziness patient suggested benign paroximal positional vertigo who is diagnosed as weakly dizziness(虛暈)showed prominent improvement by Jaeumkunbitang-gamibang(滋陰建脾湯) and Dix-hallpike maneuver.

Most inflammatory disorders are usually treated using anti-inflammatory drugs including non-steroidal anti-inflammatory drugs (NSAID) and steroidal anti-inflammatory drugs (SAID). In a prolonged use, however, they may frequently produce adverse side-effects. Thus, it is necessarily required to develop a new anti-inflammatory drug with little side-effects. Nephrite has been widely used by traditional oriental medicine to cure the various chronic diseases. In order to verify the anti-inflammatory activity of nephrite, the TPA (12-O-tetradecanoylphorbol-acetate) or the croton oil-induced edema was developed in the mouse ears and the nephrite powder suspension or the nephrite water was directly applied to the ear edema. It was found that nephrite could significantly reduce the ear swelling implying its strong potential as an active anti-inflammatory agent when comparing to indomethacin, a non-steroidal anti-inflammatory drug.

Purpose: The focal ossification of auricular cartilage is an unusual clinical entity in which the ear becomes partially or totally rigid and immalleable. This condition may result from cold injury, local trauma, inflammation, or various systemic diseases. Patients may feel mild discomfort, but there are usually no other serious symptoms. We present a case of focal ossification of auricular cartilage in which the cause is unknown. Methods: A healthy 58-year-old man presented with a 2-year history of hard mass of right posterior auricular area. He denied any precipitating historical events like cold injury and inflammation. Routine testing did not demonstrate systemic abnormalities. Ultrasonographic examination revealed a $22{\times}10{\times}11mm$ sized heterogenous isoechoic mass showing an acoustic shadow. Results: Excisional biopsy was performed under local anesthesia. Histological examination revealed the ossification with deposition of trabecular bone in normal elastic cartilage. The patient was healed without any problems and satisfied with the result. Conclusion: We report clinical experience of focal ossification of auricular cartilage, which is quite a rare clinical entity. It should be considered that there is the possibility of ossification of cartilage when it meets the benign mass of the ear.

Gamiseunggal-tang(G-tang) has long been used for the treatment of acute and chronic allergic diseases(especially, urticaria) in oriental medicine. But, It's mechanism of action is not well investigated. Anal therapy is another way of taking medicine, which is not used in common situation but available for the treatment of colon and anal diseases. It is also used in GI tract diseases, Gynecological diseases, and pediatric diseases and so on. It is especially benefitable for patients who are in such situations as coma, severe vomiting, and swallowing difficulty. In this study, the author investigated the effects of G-tang by anal therapy on acute and chronic allergic reactions in murine model. The results obtained are as follows: 1. G-tang(0.01, 0.1 g/kg) inhibited the compound 48/80-induced ear swelling response in mice. Inhibitory effects of G-tang was significant (P<0.05) at the dose of 0.01 g/kg. 2. G-tang(0.001-0.1 g/kg) inhibited the cutaneous allergic reaction activated by anti-dinitrophenyl(DNP) IgE in rats. Especially, G-tang 0.01, 0.1 g/kg inhibited the cutaneous allergic reaction significantly. 3. G-tang(0.01-1 g/L) dose-dependently inhibited the compound 48/80-induced histamine release from the peritoneal mast cells. 4. G-tang(0.001-0.1 g/L) had a inhibitory effect on anti-DNP IgE-induced tumor necrosis factor-${\alpha}$ production. Above results indicate that anal therapy of G-tang may be beneficial in the treatment of acute and chronic allergic diseases.

BACKGROUND/OBJECTIVES: The elderly are reported to have a high prevalence of nutritional anemia when they have lower intakes of nutrients or chronic diseases. This study was conducted to compare nutritional status according to nutritional anemia and to determine associations between nutritional anemia and chronic diseases in Korean elderly. SUBJECTS/METHODS: This study utilized data on 3,258 elderly aged ${\geq}65$ years gathered during the $6^{th}$ Korea National Health and Nutrition Examination Survey 2013-2015. Subjects were divided into nutritional anemia (NA) group (n = 415) and non-NA group (n = 2,843) by hemoglobin concentration. Nutrient intakes were assessed using dietary intake data obtained using the 24-hour recall method. The odds ratios (ORs) for nutritional anemia by chronic diseases were determined. Statistical analysis was performed using SPSS Ver. 23.0. RESULTS: Of 3,258 subjects, 12.7% had nutritional anemia. Intakes of potatoes, pulses, and mushrooms by males and potatoes, fruits, meats, eggs, and seafood by females were significantly lower in NA group than in non-NA group. The proportion of the subjects whose intakes of protein, vitamin A, vitamin $B_1$, vitamin $B_2$, niacin, and iron less than estimated average requirement (EAR) were significantly higher in NA group compared to non-NA group. After adjusting for age, the number of family members, energy intake, and alcohol drinking, ORs for nutritional anemia in the subjects with diabetes and myocardial infarction or angina pectoris were significantly higher by 1.74 times and 1.59 times as compared to the subjects without those diseases, respectively. However, ORs for nutritional anemia in the subjects with obesity, abdominal obesity, and hypertriglyceridemia were significantly lower by 0.64 times, 0.60 times, and 0.59 times as compared to the subjects without those diseases, respectively. CONCLUSIONS: The results of this study suggested that nutritional management should be done to enable the Korean elderly to consume foods with high hematopoietic nutrients density to prevent nutritional anemia. Korean elderly need to make regular efforts to check for nutritional anemia.

Background : The varieties of manifestations referred to oral, glottal, labial and dental diseases has been long complicated physicians in the efficient diagnosis and treatment of these diseases. Acupuncture has been widely used in Korea throughout the history and provides an efficient method in the treatment of them Objectives : Establish a distinctive and efficient acupuncture method for the treatment of oral, glottal, labial and dental diseases based in literature research Method : We reviewed four Korean medical literature, "Guide to Swollen Sore Treatment", "Treasured Mirror of Eastern Medicine", "Experiential Prescriptions of Acupuncture and Moxibustion", and "Essential Rhymes on Acupuncture and Moxibustion by Master Sa-am", and analyzed the therapeutic characteristics in the treatment of oral, glottal, labial and dental diseases Result : 1. According to "Guide to Swollen Sore Treatment", we could noted frequent application of blood letting methods in the affected area, then rinse ones mouth with salty water and further application of taro plaster. Also found acupuncture methods utilizing heated mole cricket or silkworm in the sublingual region. Regarding herbal method, Realgar was rubbed in the affected area. Mainly used acupuncture points in the treatment of oral, glottal, labial and dental diseases were GV20, GB20, LU5, and auricular anterior hairline 2. In "Treasured Mirror of Eastern Medicine", blood letting method in the sublingual region and burning needle searing method were the most frequently applied in the treatment of oral, glottal, labial and dental diseases. Moxibustion was also applied in the treatment of labial and dental diseases. Particularly, said to apply 3 moxa cones in ear zones of both sides, when no medicine is effective. This demonstrates how emphasized the importance of moxibustion in this kind of disease. Mainly used acupuncture points were GV16, CV24, LI4, EX-HN12, and EX-HN13 3. In "Experiential Prescriptions of Acupuncture and Moxibustion", no other methods beside wrist. Superstitious methods like applying moxibustion on the tooth picture drawn on the roofing tile need further confirmation. Mainly used acupuncture points were LI4, ST36, and HT7. 4. "Essential Rhymes on Acupuncture and Moxibustion by Master Sa-am", identified the cause of diseases according to visceral pattern identification. Stomach and Spleen in charge of vocal, lingual, and labial disease, Kidney for dental disease, and further scrutinizing identification according to Liver, Heart, Stomach, Lung, and Kidney manifestations. Used supplementation and draining needling methods of self meridians and other correlating meridians. Conclusions : After previous study on stroke and eye diseases, we could also find various efficient methods according to oral, glottal, labial and dental diseases, through literature research of korean medical classics. This study will concurrently result in establishing distinctive therapeutic method characteristic of Korea.
