چکیده
A comparison of the chemical composition of the nerve fibers from the corpus callosum and from the lumbosacral intradural nerve roots in man and in the dog was undertaken in order to determine whether in these two mammals the relative amount of sheathing substance is the same in t,he two divisions of the nervous system, the cal!osum representing the central and the nerve roots the peripheral system. By sheathing substance is meant the myelin sheath which surrounds the axis cylinder and which gives myelinated nerve fibers their glistening white appearance. The term “white matter” has been applied to groups of myelinated fibers as these appear in the

Review of the Aspergillosis and Report A Case of its Central Nervous System
SUMMARY Because Aspergillus SP. are one of the most common airborne fungal contaminants in all parts of the world, the incidence of Aspergillosis is relatively high, but will not be diagnosed in some cases. In this survey we decided to review the importance of Aspergillosis and also to report a case of its Central Nervous system involvement in a patient without Immunodeficiency.
متن کاملA Case Report of Primary Angiitis of the Central Nervous System
BACKGROUND AND OBJECTIVE: Primary angiitis of the central nervous system (PACNS) is an inflammatory vasculitis with very low frequency and prevalence. It is not clear why the inflammatory process of this disease is limited to cerebrovascular disease without systemic manifestations. A case of primary angiitis of the central nervous system with cerebrovascular manifestations is reported here. C...
متن کاملDeletion of histidine decarboxylase (HDC) enhances the antinociceptive effects of orexin A in the central nervous system
It has long been established that histamine plays a role as a mediator of inflammation. From numerous studies, it has been well known that the amine has many pharmacological actions on a variety of organs. To evaluate the role of histamine in pain perception, we generated HDC knockout mice using a gene targeting method. Histamine is a hydrophilic autacoid, and in most tissues it is stored and s...
متن کاملAutoimmune Hemolytic Anemia preceding the Diagnosis of Primary Central Nervous System Lymphoma
In this study, a 2.5-year-old boy suffering from a febrile seizure with normal laboratory tests and a history of immune hemolytic anemia was examined. Brain MRI demonstrated some tumors in the frontal, parietal, and occipital lobe that corroborated the pathology results of primary central nervous system lymphoma for the patient. The patient was treated with high- dose of Methotrexate. Our re...
متن کاملEvaluation of changes in testosterone concentration of the rat central nervous system following progesterone administration
Neurosteroids are steroids that are produced in the central nervous system (CNS). While progesterone and dehydroepiandostendione (the precursors of testosterone) are among the identified neurosteroids, it is not clear that testosterone could be considered as a neurosteroid. The testosterone synthesis has been demonstrated in the brain of castrated frog, but not in the rat brain. In the present ...
