  • Physical and psychological events can produce stress response in various degrees. Stress affects many aspects of physiology including both brain and peripheral elements which is represented as hypothalamus-pituitary-adrenal axis. Brain elements consist of corticotropin-releasing hormone(CRH), locus ceruleus(LC)-norepinephrine(NE)/autonomic system. Peripheral elements include pituitary-adrenal axis and the autonomic nervous system, which coordinate the stress response. Current trend of the stress researches is emphasizing the mechanisms of the stress response which is adaptive or become maladaptive. This review introduces 1) the concepts of stress, 2) physiological and behavioral aspects of stress responses, 3) the consequences of stress response, 4) the measurements of stress and 5) stress management for those interested in stress research.

  • It is as result that study to apply mini magnet nerve curer in peripheral nervous system disease treatment. Design and embodied action power and Control Unit in cylinder form of magnet roof object firstly. Yielded service area about special quality of probe of roof object cylinder style and treatment area dimension and distance of treatment pulse secondly. Embody pulse forming course energy value by Probe's form by third, could embody treatment pulse by disease. Specially, through a special quality experiment, saved Damping pulse form and treatment pulse form etc. variously Lately, embodied this to aid a little in disease treatment that follow that there is no invasion that there is no stimulation by medicine development Go amplitude treatment pulse (traditional magneto-therapy of greatly great that strong.) does curative effect greatest at short time and becomes thought that demand is magnified greatly at the future in this research.

  • To elucidate one of the effect of piperine on the peripheral sympathetic nervous system, influence of piperine upon the contractile action of norepinephrine, methoxamine and tyramine as well as uptake and release of $[^{3}H]-norepinephrine$ has been investigated in naive and chronic piperine-treated vas deferens of rats. $pA_2$ value for ${\alpha}_1-adrenoceptor$ of phentolamine was significantly increased. Chronic piperine-treated group was markedly shown increased efflux of $[^{3}H]-norepinephrine$ and muscular tension, but was not affected the neuronal up-take and release of $[^{3}H]-norepinephrine$. It can be concluded that potentiation of the effect of norepinephrine by acute and chronic piperine treated group may be due to the change of affinity of ${\alpha}_1-adrenoceptor$, and partly due to possible modification of storage mechanism.

  • When peripheral axons are damaged, neuronal injury signaling pathways induce transcriptional changes that support axon regeneration and consequent functional recovery. The recent development of bioinformatics techniques has allowed for the identification of many of the regeneration-associated genes that are regulated by neural injury, yet it remains unclear how global changes in transcriptome are coordinated. In this article, we review recent studies on the epigenetic mechanisms orchestrating changes in gene expression in response to nerve injury. We highlight the importance of epigenetic mechanisms in discriminating efficient axon regeneration in the peripheral nervous system and very limited axon regrowth in the central nervous system and discuss the therapeutic potential of targeting epigenetic regulators to improve neural recovery.

  • Acrylamide의 신경독성에 대해 조사하기 위하여 초기운동실조증이 유도된 생쥐의 신경계에 대한 Acrylamide의 영향을 관찰한 결과, 중추 및 말초신경조직에 있어서의 손상이 보여 척수의 전반적 공포현상, 신경원 및 신경교의 세포손상 그리고 말초신경섬유의 퇴행현상들이 보였다. 또한 이들에 대한 미세구조적 관찰에 의하여 신경원에서의 비정상적 미토콘드리아 및 척수전근 섬유에서의 수초의 균혈화 현상등이 야기됨을 알았으며 좌골신경에서의 수초의 부분적 붕괴 및 축삭형질내의 퇴행현상들도 보였다. 위와 같은 실험결과는 Acrylamide로 인한 중독의 영향이 말초신경장애의 증상으로 나타나나 최초의 신경독성효과는 중추 및 말초신경계에 대해 거의 유사한 시기에 작용함을 시사한다.

  • Neuropathic orofacial pain (NOP) is initiated or caused by a priomary lesion or dysfunction in the peripheral nervous system or the central nervous system. NOP is divided into paroxysmal and continuous by duration of pain. NOP is important for dentists, because they can occur after dental procedures, such as extractions, endodontic treatment, and dental implant insertion. Dentists should have concern about NOP, because it is difficult to diagnose and treat.

  • Breathing is controlled by complex interactions between the central and peripheral nervous systems in conjunction with the respiratory system. Neurological diseases predispose patients to nocturnal desaturation and pneumonia due to respiratory dysfunction, which increases mortality, daytime sleepiness and fatigue, and reduces the quality of life. Respiratory function tests are required to identify respiratory function decline and to consider compensatory management. This review summarizes the characteristics of several respiratory function tests and their applications to neurological diseases.

  • Chandanasav is an Ayurvedic preparation slightly reduced the gastrointestinal motility at the 15 min time interval. It increased the latent period of castor oil induced diarrhoea, slightly decreased number of stool count and lowered the purging index values. Chandanasav significantly reduced the onset and increased the duration of pentobarbital induced sleeping time. No significant analgesic effect was observed from the hot plate study Thus it may have mild constipating and central nervous system depressant activity without any effect on peripheral nervous system.

  • The expression of nestin and vimentin in the spinal nerve roots of rats with experimental autoimmune encephalomyelitis (EAE) was studied to ascertain whether Schwann cells in the peripheral nerves respond to acute central nervous system autoimmune injury. Immunohistochemistry demonstrated that nestin was constitutively expressed in the dorsal roots of spinal nerves in control rats; its expression was enhanced in the spinal nerve roots of rats with EAE. Vimentin expression was weak in control rat spinal nerve roots, and it was increased in the dorsal roots of rats with EAE. It is postulated that normal animals have multipotent progenitor cells that constitutively express nestin and vimentin in the spinal nerve roots. In response to an injury of the central nervous system, these multipotent Schwann cells are activated in the spinal nerve roots through the expression of the intermediate filament proteins vimentin and nestin.
