Objective : To evaluate autonomic nerve balance and sympathetic nerve activity in patients with inner ear dysfunction as examined by heart rate variability(HRV) Research Methods and Procedures : One hundred and twenty three patients(between 15 to 59 years old) who visited Dept. of Oriental medical Opthalmology & Otolaryngology, Kyunghee university and had an examination of HRV test, were selected as subjects of our study. We checked items of HRV test(such as SDNN, RMSSD, LF, HF, TP, norm-LF, norm-HF, LF/HF ratio), and analyzed time and frequency domain differences between three groups classified as tinnitus, hearing loss and vertigo. And we compared HRV items(such as SDNN,RMSSD, TP and LF/HF ratio) with standard levels. Results and Conclusion : Our results showed no significant differences between three groups in HRV items except for mean heart rate. Patients with inner ear dysfunction showed significant lower TP than 2000$(ms^{2})$(p <0.001) and significant higher LF/HF ratio than 1.5(p=0.003). So we suggest that patients with inner ear dysfunctions such as tinnitus, vertigo and hearing loss, have sympathetic hypertonus and inactivity of autonomic nerve regulation.

Objectives : This study is designed to analyze the outpatients who received medical treatments for ear diseases in ophthalmology & otolaryngology & dermatology clinic of Daejeon Korean Medical Hospital from March, 2013 to February, 2019. Methods : We classified the otology outpatients who received medical treatments in ophthalmology & otolaryngology & dermatology clinic of Daejeon Korean Medical Hospital from March, 2012 to February, 2019 according to gender, year, age, season, anatomical parts, and main diagnosis. The statistical analysis was performed using SPSS 25.0. Results : 1. The number of outpatients with ear diseases were 880; 505 female and 375 male. The number of female patients were approximately 1.7 times higher. 2. The average age of the outpatients with ear diseases were 50.0. The number of middle-aged (40-50s) patients were 439, which is almost half the number(49.9%) of the whole patients. 3. By analyzing the number of patients classified by year, we found out that the number of the outpatients with ear diseases has increased gradually for the past 7 years. 4. In the analysis of the number of patients classified by the anatomical parts of the ear, the inner ear diseases group were the largest, amounting to 79.3% of the whole patients. 5. In the analysis of the number of patients classified by main diagnosis, Tinnitus turns out to be the largest group with 338 patients, followed by sudden sensorineural hearing loss, dizziness, otalgia, Meniere's syndrome, otitis, auditory tube dysfunction, BPPV. 6. No statistical-significant difference were shown in the analysis of the number of patients classified by season. Conclusions : It turns out that patients with ear diseases had increased by the years, and middle aged patients (40-50s) were the largest among the age groups. Most of the patients came for the inner-ear diseases, and tinnitus, sudden sensorineural hearing loss took up the largest proportions.

The radix of Pueraria thunbergiana BENTHAM (Leguminosae) is traditionally prescribed to attenuate the clinical manifestations of inner ear dysfunction and various clinical situations including fever, gastrointestinal disorders, skin problems, migraine headaches, lowering cholesterol and treating chronic alcoholism in Oriental Medicine. In the present study, we examined the effect of ethanol extract of P. thunbergiana radix (EPR) on cisplatin-mediated HEI-OC1 auditory cell death. In addition, to investingate the protection mechanism of EPR on free radicals. Treatment of EPR protected cells from cisplatin and reduced lipid peroxidation in a dose-dependent manner. Furthermore, EPR demonstrated significant scavenging activity against various free radicals, including superoxide radical, hydroxyl radical, hydrogen peroxide, and DPPH radical. These results indicate that EPR protects cisplatin-induced damages of HEI-OC1 cells through inhibition of lipid peroxidation and augmenting scavenging activities against free radials.

A mechanism of hair cell damage caused by noise and ototoxic agents is mediated through generation of free radicals and reactive oxygen species(ROS). It is known that most of animals have defense systems of ROS that protect against ROS, and the cochlea of animals also has ROS defense system, which appear efficient in detoxifying ROS generated under normal condition. This system includes several antioxidant enzymes such as superoxide dismutase(SOD), catalase(CAT), glutathione peroxidase (GPX), and glutathione reductase(GR). The radix of Pueraria thunbergiana(P. thunbergiana) is traditionally prescribed to attenuate the clinical manifestation of inner ear dysfunction and various clinical situations including fevers, gastrointestinal disorders, skin problems, migraine headaches, lowering cholesterol, and treating chronic alcoholism in Oriental Medicine. In the present study, to investigate the protection mechanism of ${\beta}-sitosterol$ from P. thunbergiana on cisplatin cytotoxicity toward HEI-OC1, we measured the effects of ${\beta}-sitosterol$ on activities of SOD, CAT, GPX, and GR in cisplatin treated cells. SOD, CAT, GPX, and GR activities were significantly increased in the presence of 0.001-0.1 ${\mu}g/ml$ of ${\beta}-sitosterol$ compared to the control group. These results indicate that ${\beta}-sitosterol$ protects cisplatin-induced HEI-OC1 cell damage through increasing the antioxidant enzyme system such as SOD, CAT, GPX, and GR.
