  • In general. it is known that central nervous system associated with nerve injury and regeneration in mature cann't regenerate, unlikely peripheral nervous system, due to various reasons. Although a lot of Patients arc suffered with central nervous system injury in the world, but there art a few resolution and researches and investigations. 'rho effect of central nervous system regeneration was partly revealed by many researchers. In this article, we describe about recovery (inclusive of axonal regeneration, remyelination, repair of spinal cord) and associated factors(inclusive of macrophage and autoimmune T-cell. neural stem cells. Nogo) after central nervous system injury.

  • Through previous studies, the central nervous system (CNS) was collected by dividing the scuttle fly into larval, pupa, and adult stages by developmental stage, and the morphological characteristics were observed. In situ hybridization (ISH) using the collected central nervous system, it was possible to confirm the location and extent of expression of the neurotransmitter corazonin (Crz) at each stage of development. In this study, paraffin specimens were prepared using central nervous system tissues of 3rd instar larval stage of scuttle fly, which had completed in situ hybridization, and general histochemical staining (hematoxylin-eosin, H-E) and special histochemical staining (luxol fast blue-cresyl violet) was performed to observe the histological and cytological morphology characteristics of corazonin neurons. As a result, a variety of nerve cell body existed between many myelin sheath. The corazonin neurons compose cortex of central nervous system with other neurons congregating in this tissue and show larger cell body relatively in neurohistochemical analysis.

  • In order to investigate pharmacological properties of New Wonbang Woohwangchungsimwon Pill (NSCH) and Wonbang Woohwangchungsimwon Pill (SCH), the effects of NSCH and SCH on cerebral ischemia and central nervous system were compared. Cerebral ischemia insult was performed using unilateral carotid artery occlusion in mongolian gerbils. The histological observations showed preventive effects of NSCH and SCH treatments with ischemia-induced brain damage. The ATP in brain tissue was decreased in vehicle-treated ischemic gerbils. This decrease was prevented by SCH treatment. In contrast to what was inhibited by NSCH and SCH treatments. While NSCH and SCH had no effects on the hexobarbital-induced sleeping time, they prevented the seizures induced by electric shock and strychnine. NSCH and SCH showed sedative effect in rotarod and spontaneous activity test. Furthermore, NSCH and SCH showed anti-stress effect. Our findings suggest that the pharmacological profiles of NSCH on cerebral ischemia and central nervous system are similar to those of SCH.

  • Objective : The purpose of these research was to investigate effects of water extract of Bistortae Rhizoma(BRE) on the hemostasia, anti-inflammatory action and central nervous system. Methods : we used mice and rats administered with the extract of the above herbs. Results : BRE decreased the permeability of evans blue into peritoneal cavity and cotton pellet granuloma formation. BRE did not decrease the acetic acid induced writhing syndrome and the histamine induced mouse paw edema. BRE inhibited the pentylenetetrazole and the strychnine induced convulsion. BRE shortened the bleeding time and plasma prtrombin time. BRE did not affect on the proliferation of Balb/c 3T3 cells. Conclusions : these results suggest that the effects of BRE are the hemostasia, anti-inflammatory action, and mild depressant activity of central nervous system.

  • Primary central nervous system lymphoma (PCNSL) is a type of non-Hodgkin lymphoma confined to the central nervous system. Its diagnosis requires a stereotactic biopsy, which is an invasive procedure. Cerebrospinal fluid (CSF) analysis is less invasive and easier to perform than a stereotactic biopsy. We hereby report a PCNSL case diagnosed using CSF analysis and treated with systemic chemotherapy.

  • This study is an attempt to investigate the effects of the water extracts of the whole plants of Prunella vulgaris (Labiatae) and Thesii chinense (Santalaceae) on the acute toxicity, the activities on central nervous system and the diuretic action. The acute toxicities shown by $LD_{50}$ were estimated to be more than 3000 mg/kg p.o. and 1,000 mg/kg s.c. in the extracts of Prunellae Herba and Thesii Herba, respectively, in mice. The extracts at a dose of 2,000 mg/kg p.o. did not show any activities on central nervous system, i.e, sedative, analgesic, hypothermic and anticonvulsant actions. The urination in rats was increased by 45.5% and 57.6% when 100mg/kg of each of the extracts were given orally. The results obtained revealed that the water extracts possessed weak diuretic actions without any of central nervous system activities. Furthermore, it is considered that the potassium in the extract may play a role in the diuretic action.

  • The development of the central nervous system is a continuous process during the embryonic and fetal periods. For a better understanding of congenital anomalies of central nervous system, three major events of normal development, i.e., neurulation (3 to 4 weeks), brain vesicle formation (4 to 7 weeks) and mantle formation (over 8 weeks) should be kept in mind. The first category of anomalies is neural tube defect. Neural tube defects encompass all the anomalies arise in completion of neurulation. The second category of central nervous system anomalies is disorders of brain vesicle formation. This is anomaly that applies for "the face predicts the brain". Holoprosencephaly covers a spectrum of anomalies of intracranial and midfacial development which result from incomplete development and septation of midline structures within the forebrain or prosencephalon. The last category of central nervous system malformation is disorders involving the process of mantle formation. In the human, neurons are generated in two bursts, the first from 8 to 10 weeks and next from 12 to 14 weeks. By 16 weeks, most of the neurons have been generated and have started their migration into the cortex. Mechanism of migration disorders are multifactorial. Abnormal migration into the cortex, abnormal neurons, faulty neural growth within the cortex, unstable pial-glial border, degeneration of neurons, neural death by exogenous factors are some of the proposed mechanism. Agyria-pachygyria are characterized by a four-layerd cortex. Polymicrogyria is gyri that are too numerous and too small, and is morphologically heterogeneous. Cortical dysplasia is characterized by the presence Q[ abnormal neurons and glia arranged abnormally in focal areas of the cerebral cortex. Neuroglial malformative lesions associated with medically intractable epilepsy are hamartia or hamartoma, focal cortical dysplasia and microdysgenesis.ysgenesis.
