후각장애를 가져오는 질환에는 비, 부비동 질환, 두부외상, 상기도 감염, 간질 및 노인성치매 등의 신 경게 질환, 칼만증후군과 같은 대사성 질환 등이 있으나, 현실적으로 후각장애의 정도를 측정하기가 쉽 지않고, 후각역치가 개인간에 차이가 많아 아직 연구가 미진한 상태이다. 특히 교통사고나 산업현장에서 쉽게 접할 수 있는 두부외상이나 독성화학물질 등에 의해 후각장애가 많이 나타나고 있으나 아직 보상의 기준이 없어 환자들이 어려움을 겪고 있다. 두부손상 후에 발생하는 후각장애는 병원에서도 놓치기 쉬우며, 알아내더라도 두렷한 치료방법이 없기 때문에 간과되어온 것이사실이다. 그러나, 이런 후각장애 환자들은 집안에서 가스가 새는 것을 느끼지 못하며, 화재로연기가 나더라도 알아차리지 못하고, 음식이 상해도 잘 모르므로 위험에 빠지기가 쉽고, 후각에 이상이 있으면 자연적으로미각도 감소하므로 식욕도 떨어지고, 때로는 우울증에 빠지기도하며, 주부의 경우에는 음식을 만들기가 어렵게 된다. 두부외상을 받은 전체 환자 의 약5 -10%에서 후각장애가 나타나는 것으로 알려져 있으나, 냄새가 나지만 정확히 무슨 냄새인지 이름을 대지 못하거나 어떤 냄새를 다른 냄새와 감별하지 못하는 경우까지 합하면 대개 20-30%로 생각된다. 두부 손상 후의 후각장애의 정도는 얼마나 크게다쳤는 가에 달려있지만, 조금 다치더라도 후각장애가 심한 경우도 있다.

Olfactory dysfunction is one of the most common complaints of patients with chronic rhinosinusitis. Patients who suffer from olfactory dysfunction report a negative effect on their overall quality of life. Chronic rhinosinusitis-related olfactory impairment is the most treatable form of olfactory disorder; however, outcomes after endoscopic sinus surgery (ESS) are challenging to predict. Previous studies have documented a wide range in overall improvement after ESS. The purpose of this study is to review the factors that predict changes in olfaction after ESS.

The olfactory system is an important model for the study of neuronal degeneration and regeneration, including neuronal diseases. When the olfactory sensory neurons are damaged by nerve injury or are exposed to environmental factors, they degenerate and are replaced by regenerating neurons. To monitor neuronal degeneration in living animal, we established an olfactory-specific GFP transgenic zebrafish. The effects of Triton X-100 or sodium acetate on the olfactory system were examined. A significant decrease in the number of GFP-positive olfactory sensory neurons was observed after chemical lesion. We found a recovery of GFP-positive neurons by 2 days posttreatment. From these results, we expect that further studies of olfactory degeneration and regeneration using this transgenic zebrafish will provide important advances for the study of neuronal degeneration and regeneration.

This article addresses the possibility of developing a new art appreciation method using olfaction, which was not previously considered an important sense in expanding the cultural enjoyment of visually impaired people. The human olfactory system is a faculty that is not considered very important in modern society; however, this is due to cultural factors, and from a biological point of view, the human sense of smell has sufficient potential for practical application. In this study, it is assumed that when various types of scent are perceived through this sense of smell, each has its own unconscious relation to color and concept, which researchers have termed "color directivity" and "concept directivity." Through experiments, the researchers found that some specific scents have color directivity and concept directivity, and in using these scents, they succeeded in delivering information about colors used in artworks to the visually impaired. Based on this study, we hope to continue our research on the use of color-concept directional scents that can convey the brightness and saturation of colors and more diverse hues.

Purpose: Symptoms of idiopathic Parkinson's disease (PD) include tremors, bradykinesia, and rigidity. The purpose was to explore the effects of breathing, meditation and qigong on the improving of insight, behavior, mood discomfort, depression, anxiety, and olfactory dysfunction, which are PD non-motor symptoms. Methods: Three stages of An's-4444 healing breathing, An's Gwanjeong healing meditation, and healing qigong performed 12 times for 80 minutes at a time in subjects with PD (11 patients), and pre- and post-measurements compared and evaluated. Results: The Integrated Parkinson's Rating Scale (UPDRSI) for mood discomfort after 12 healings was 69%. The Depression Scale (61%) for HAMD, and 64% for Anxiety (HAMA)), and the smell identification test (TSI) for a trial for olfactory dysfunction, improved to 82%, respectively. However, the numerical values after one month after 12 healing were almost same in all four scales. This means that the healing effect maintained until after one month. Conclusions: An's healing breathing, meditation and qigong therapy significantly improved insight, behavior, and mood discomfort, and non-motor symptoms such as depression, anxiety, and olfactory dysfunction. These results suggest that An's breathing, meditation and qigong therapy are valuable as a primary therapy to improve and heal non-motor symptoms in Parkinson's disease patients. Further research in biomedical science is needed.

자연적인 서식지에서 토끼는 번번히 육식 동물의 먹이가 된다. 이들의 일차적이고 우선적인 생존 반응은 발견을 피하기 위한 노력으로 조용히 있는 것이다. 토끼는 폭발적인 속도를 빠르게 낼 수 있고 짧은 거리에서 즉시 방향을 바꿀 수 있도록 가벼운 뼈, 작은 앞다리, 강력하고 잘 발달된 뒷다리를 가졌을 뿐만 아니라, 예민한 청각과 즉각적인 후각을 발달시킴으로써 'fight or flight(적자생존)'로 적응해왔다. 이런 생존 반응은 욕구가 없어진 것으로 나타나는 대부분의 집토끼에도 여전히 존재하지만, 이런 토끼들은 장애에 대해 반응이 불완전하고 변화에 쉽게 스트레스를 받는다. 스트레스를 받은 동물은 일차적으로 anorexia와 용변의 빈도와 일관성에 변화를 유발하는 건강, 생식, 행동적인 문제에 더욱 민감하다.

Objectives The purpose of this study is to report the case of an olfactory disorder in two patients combined by intranasal acupuncture treatment. Methods The authors mainly performed infrared irradiation while acupuncturing nasal and bilateral Yeonghyang-hyeol (迎香穴, LI20) in two patients with olfactory disorder. In addition, nasal lasers were irradiated for 5 minutes, these help to communicate meridians and control chi-shue (氣-血). Depending on the sub-symptoms of each patient, we were acupuncturing Indang-hyeol (印堂穴) or herbal medicine treatment which is Hyunggaeyungyo-tang (荊芥蓮翹湯), Bangpungtongsungsan (防風通聖散), Gamiygin-tang (加味二陳湯) was also performed. Results The patient's nasal symptoms were alleviated by intranasal acupuncture treatment. Conclusions There are no clinical studies in regards to acupuncture treatment in olfactory disorder so far. However, this study demonstrated positive health outcomes on olfactory disorder from intranasal acupuncture treatment.

Purpose : The importance of meniscal repair is well recognized. But transeciton of the posterior horn of the medial meniscus at the posterior tibial attachment is rarely documented and known irreparable. We experienced 9 cases of transection, and present clinical features and pull out suture technique. Methods and Materials : There were 9cases of transection of the posterior horn of medial meniscus from September 1998 to July 1999 in our hospital. Age was 59.3 years in average and ranged from 38 to 70years. Clinical features and MRI made diagnosis in all cases. We confirmed the diagnosis with arthroscopy and repaired the transection with pullout suture technique. Clinical features : Transection of the posterior horn of the medial meniscus at the posterior tibia attachment occurred frequently in middle aged people. They complained posterior knee pain, but they have no history of definitive trauma. Characteristically they had difficulty in full flexion of the knee and in having a squatting position. MRI is very important in diagnosis of transection, especially in coronal view, there is separation of the posterior horn of the meniscus from the posterior tibial attachment. Surgical technique : Pullout suture technique includes debridement of fibrous or scar tissue, exposure of the subchondral bone of the posterior tibial attachment site, suture the transected end of the meniscus with PDS suture, bone tunnel formation from the anteromedial aspect of the proximal tibia, insertion of wire loop through the tibia tunnel, pull the PDS suture through the tibia tunnel out of the joint and stabilize the PDS with post-tie technique to the proximal tibia. Conclusion : Transection of the posterior horn of the medial meniscus at the posterior tibial attachment is not common clinically and rarely documented. Clinical features and MRI are very important in diagnosis of this type tear. Arthroscopic pullout sutures is useful for treatment of this type tear of the meniscus.

Objectives : The purpose of this study is to report the effect of Korean medicine on olfactory disorders due to chronic sinusitis. Methods : Two patients with chronic sinusitis complaining of olfactory disturbances, nasal obstruction, and purulent discharge were treated with herbal medicines and acupuncture treatment. The nasal endoscopic examination and paranasal sinuses x-ray series (PNS x-ray) were performed. In addition, numeral rating scale (NRS) of olfactory disturbances and degrees of nasal obstruction and purulent discharge were evaluated. Results : In cases 1 and 2, NRS of olfactory disturbances decreased from 9 to 1. Nasal obstruction and purulent discharge decreased to no symptoms or intermittent level at moderate or severe level. The endoscopic findings and PNS x-ray findings were improved after treatments. Among various treatments of Korean medicine, Gamitonggyu-tang may play a crucial role in the reduction of sinusitis and olfactory disorders. Conclusions : This case report can be used as a basis for the use of Korean medicine, Gamitonggyu-tang, for olfactory disorder due to chronic sinusitis.
