第四章 神经系统疾病的辅助诊断方法（The fourth chapter is the auxiliary diagnostic method of nervous system diseases） The fourth chapter is the auxiliary diagnostic method of nervous system diseases (The, Special, Techniq, Je$for, Neui, ologic, Diagnosis), the first section of cerebrospinal fluid examination CSF (cerebzt~pinal nu.d CSF) is a colorless transparent liquid in the ventricle and subarachnoid space, mainly by the choroid plexus ([6exus cbonoideus) secretion through the interventricular foramen (Monro hole) into the third ventricle, midbrain aqueduct and fourth ventricle, the fourth ventricle in Q hole (Lu HKA made a hole) and two side holes (Magendie hole), flow to the brain and spinal cord of the subarachnoid cisterns and. Most csF are absorbed by the arachnoid membrane of the brain fornix, superior to the sagittal sinus (upenor bngttudinal sinuses), and a small portion is absorbed by the spinal nerve root space. Qi CSF total is 110 - 200ral, the average 130m1., its generating speed is 0 35ml / rain, about 500ral per day. That is, the bodys csF can be updated 3 - 4 times a day. In acute or chronic inflammation, edema and choroid plexus papilloma, the secretion of csF increased significantly, reaching 5000 - 6000ral, D. Normally, a variety of chemicals in the blood can only be selectively entered into human csF, a function called the Jbloobrain barrier (BBB). Under pathological conditions, BBB damage and its increased permeability can change the composition of csF. Usually after lumbar puncture to take csF, special circumstances and feasible cisterna magna (cerebell~-medullar elsterna) or lateral ventricle puncture (1ateral Ji ebral 30 trleulu8) puncture; diagnostic puncture (diagnostic puncture) can also be injected and air are developing Jing angiography to observe the spinal subarachnoid space, cerebral ventricle and subarachnoid space system; therapeutic puncture (therapeu ie puncture) is the main injection of drugs.
