  • Strabismus is a misalignment of eye, and which devided paralytic and non-paralytic strabismus. Paralytic strabismus is generally a neurological problem, especially 3rd, 4th or 6th nerve. The abducent nerve was most common affected. Paralytic strabismus are treated based on the theory of Oriental medicine with herbal medicine bal-san(發散) and gue-pung(祛風) effects and acupuncture around the eyes and etc. Authors experienced one case of the strabismus of abducent nerve palsy, 35-year-old male, showed disorder abduction of Lt. eye, diplopia and dizziness. Disorder abduction of Lt. eye, diplopia and dizziness and cervical pain improved under the treatment of acupuncture and herbal medicine Thus further clinical study and treatment principle should be made to raise the recovery rate for paralytic strabismus and it's effectiveness of Oriental medical treatment should be informed.

  • Attention Deficit Hyperactivity Disorder (ADHD) is one of the most common neurological disorders in children. The diagnosis of ADHD in children is based on the interviews and observation reports of parents or teachers who have stayed with them. Since this approach cannot avoid long observation time and the bias of observers, another approach based on Electroencephalography(EEG) is emerging. The goal of this study is to develop an assistive tool for diagnosing ADHD by EEG classification. This study explores the frequency bands of EEG and extracts the implied features in them by using the proposed CNN. The CNN architecture has three Convolution-MaxPooling blocks and two fully connected layers. As a result of the experiment, the 30-60 Hz gamma band showed dominant characteristics in identifying EEG, and when other frequency bands were added to the gamma band, the EEG classification performance was improved. They also show that the proposed CNN is effective in detecting ADHD in children.

  • The chicks from 6 field broiler farms revealed peripheral neuropathy including leg weakness, curled toes and drooped wings. Grossly distinctive enlargements of sciatic nerve, branchial nerve and lumbar nerve were observed in the chicks. Histologically nerve lesions consisted of demyelination of myelin sheaths, Schwann cell proliferation and swelling, and interstitial edema in the peripheral nerves of all birds examined. Axonal swelling and infiltration of small lymphocytes were observed, but not a primary lesion. After treatment of riboflavin, neurological disorder was markedly recovered. From these results, it is suggested that the peripheral nerve lesions in these cases were caused by dietary riboflavin deficiency.

  • Epilepsy is a paroxysmal disorder caused by abnormal electrical discharges of the brain. As it is characterized by episodic seizures with intervening normal neurological states, some temporal patterns of seizure attacks can be traced. Sleep and wakefulness patterns are one of several factors influencing seizure occurrence. In this article, physiological and pathological influences of sleep on the seizure phenomenon were reviewed. Understanding this relationship between sleep and epilepsy might lead to better understanding of sleep and epilepsy themselves, thus leading to better diagnosis and treatment of each disease.

  • Wernicke's encephalopathy (WE) is an acute neurological disorder resulting from thiamine deficiency. Early diagnosis and treatment of WE is important to avoid persistent brain damage. Although histopathologic examination usually demonstrates pin-point hemorrhages in affected brain parenchyma, secondary hemorrhage is a rare but serious complication of WE. We experienced a rare case of intracranial hemorrhage related to WE in a 56-year-old male patient with malnourishment.

The Relationship Between Sensory Processing and Emotional Regulation : A Literature Review (감각처리와 감정조절의 관련성에 대한 문헌고찰)

  • Objective : The goal of this study was to investigate neurological mechanism of emotional regulation and to examine the relationship between the regulation and sensory processing. Subjective : Emotional regulations are mainly processed in limbic system, particularly the basal-lateral group of amygdala takes on a major role in the regulations. The basal-lateral group of amygdala links to thalamus directly and/or indirectly which processes sensory information together. This sensory information connects to orbital and medial prefrontal cortex. Inadequate sensory processing may cause difficulties in emotional regulations and behaviors because of a circuit linking the amygdala, the thalamus, and the orbital and medial prefrontal cortex. These difficulties and impairments has been reported in neurological studies for children with ASD and ADHD. Conclusion : Neurological states are different between the normal children and children with ASD and ADHD and these represent various aspects in sensory processing, emotional regulations and behaviors. Thus, therapists working with children with ASD and ADHD need to understand mechanisms of sensory processing and emotional regulations in order to provide adequate treatments.

  • Sensory integration started as a theory to provide a occupational therapist with a useful frame for explaining and intervening the problems which children have. Most researches on sensory processing disorder (SPD) have been found empirical evidence to support the sensory integration theory by measuring behavioral manifestations of SPD. Recently, researchers who are interested in the diagnosis of SPD have begun to use neurophysiological methods to establish objective evidence for sensory integration. These studies reported the neurophysiological indexes reflecting the maladaptive behaviors as well as the difference between children with SPD and typically developing children in using electrodermal activity, vagal tone, EEG. Future neurophysiological studies on SPD will be expected to prove the efficacy of sensory integration intervention.

  • Effort to improve balance ability in the field of rehabilitation has been constantly issued and developed up to now. A variety of subcomponent of postural control including function and cognition should be needed in many body systems and be complicatedly linked to each system. In South Korea, although decreased postural dysfunction due to neurological or musculoskeletal disorders has been well documented, we do not have many experience and knowledge of vestibular rehabilitation for maintain and improve balance function. In the United States, vestibular physical therapy is already acknowledged as clinical subspecialty by American Physical Therapy Association. However, there is no curriculum subject related to vestibular rehabilitation in standard education of physical therapy and no specialist who has clinical experience and knowledge of this realm. Therefore, we reviewed general information and basic knowledge of vestibular rehabilitation such as current state of vestibular disorder in South Korea, pathology, major causes of vestibular dysfunction including peripheral vestibular disorders, vestibular neuritis, benign paroxysmal positional vertigo, and central disorder, evaluation of vestibular dysfunction, and treatment for vestibular dysfunction new approaches. We expect that physical therapist in South Korea recognize clinical significance of vestibular exercise and that clinical concern and research will be begun in near future.

  • Transposable elements are one of major sources to cause genomic instability through various mechanisms including de novo insertion, insertion-mediated genomic deletion, and recombination-associated genomic deletion. Among them is Alu element which is the most abundant element, composing ~10% of the human genome. The element emerged in the primate genome 65 million years ago and has since propagated successfully in the human and non-human primate genomes. Alu element is a non-autonomous retrotransposon and therefore retrotransposed using L1-enzyme machinery. The 'master gene' model has been generally accepted to explain Alu element amplification in primate genomes. According to the model, different subfamilies of Alu elements are created by mutations on the master gene and most Alu elements are amplified from the hyperactive master genes. Alu element is frequently involved in genomic rearrangements in the human genome due to its abundance and sequence identity between them. The genomic rearrangements caused by Alu elements could lead to genetic disorders such as hereditary disease, blood disorder, and neurological disorder. In fact, Alu elements are associated with approximately 0.1% of human genetic disorders. The first part of this review discusses mechanisms of Alu amplification and diversity among different Alu subfamilies. The second part discusses the particular role of Alu elements in generating genomic rearrangements as well as human genetic disorders.

  • Objectives: This is a case report regarding the effect of Korean traditional medicine on vision disorder and quadriplegia in a patient with neuromyelitis optica. Methods: We treated a patient who was diagnosed with neuromyelitis optica with Korean traditional medicine, including acupuncture, moxibustion, and herbal medicine (Gigugyanghyeol-tang gamibang) for 106 days. We evaluated the patient with the International Standards for Neurological Classification of Spinal Cord Injury (ISNCSCI), Modified Barthel Index (MBI), Modified Ashworth Scale (MAS) Grade, and Numeric Rating Scale-11 (NRS-11). Results: After treatment, the patient's symptoms were improved. The ISNCSCI scores increased from 42 to 66 in motor score, from 152 to 196 in sensory score, and from A to D in the ASIA impairment scale; the MBI score increased from 9 to 33, while the score of the MAS Grade decreased from I+ to I, and the NRS-11 scores of vision disorder, spasticity, and tingling decreased from 10 to 7, 3, and 2-3, respectively. Conclusions: Korean traditional medicine may be effective for treatment of vision disorder and quadriplegia in patients with neuromyelitis optica.
