  • 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.

  • Primary central nervous system T-cell lymphoma (PCNSTL) is an extremely rare type of brain tumor. There are only few reports on the imaging findings of patients with PCNSTL. Herein, we report the imaging findings of a patient with peripheral T-cell lymphoma-not otherwise specified that presented with numerous small nodular and patchy strongly enhancing lesions on MRI.

  • 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.

  • 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.

  • The effed of acrylamide on the nervous system has heen morphologically studied using light and electron microscopes. The light micrographs on central and pedpheral nervous tissues of mouse treated with acrylamide monomer showed total vacuolation of spinal cord, cell degradation containing neuron and neuroglia, and distal nerve fiber degeneration. The electron micrographs showed ultrastrudural changes. Abnormal mitochondria in neuron, splitting of myelin sheath in lumbar ventral root nerve, partial disintergration of myelin sheath and axoplasmic degeneration in sciatic nerve, and overafl polyneuropathies in nervous system were observed. These results suggest that acrylarnide intoxicated mouse shows distal behavioral neuropathy as an earlist clinical sign, but the initial effect of acrylamide on the nervous system seems to appear at nearly the same time in both central and peripheral nervous systems.

  • 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.
