cerebrospinal fluid substance P

Substance P is a biologically active 11-peptide substance extracted from brain or intestinal tissue. The molecular weight is 1340, which has the function of contracting smooth muscle and dilating blood vessels. The central nervous system has the highest content of substantia nigra, followed by the fourth ventricle, inferior colliculus, midbrain, hypothalamus, caudate nucleus, etc., with little content in the cerebral cortex, gray matter content higher than white matter, with obvious dilated blood vessels and The effect of reducing peripheral resistance is related to the introduction of pain. Basic Information Specialist classification: examination classification: cerebrospinal fluid examination Applicable gender: whether men and women apply fasting: fasting Analysis results: Below normal: The acute phase of cerebral embolism can be reduced. Normal value: C substance in cerebrospinal fluid: 287.43-683.45pmol/L Above normal: 1. See the acute phase of ischemic cerebrovascular disease, hemorrhagic cerebrovascular disease and so on. 2. Brain trauma began to rise after 24h. negative: Positive: Tips: Take CSF 2ml in a pre-cooled plastic tube. Aprotinin (1000 KIU/ml) was added and placed at -40 °C. Normal value 485.44±198.01 pmol/L. Clinical significance In the acute phase of ischemic cerebrovascular disease, the content of hemorrhagic cerebrovascular disease increased, and brain trauma began to increase after 24 hours. The acute phase of cerebral embolism can be reduced. High results may be diseases: precautions for hypertensive cerebral hemorrhage Take CSF 2ml in a pre-cooled plastic tube. Aprotinin (1000 KIU/ml) was added and placed at -40 °C. Inspection process Use radioimmunoassay. Not suitable for the crowd 1. If there is obvious papilledema or cerebral palsy, contraindications are contraindicated. 2. Patients who are in shock, exhaustion or endangered state and local skin inflammation, and lesions in the posterior cranial fossa are contraindicated. Adverse reactions and risks If the patient has symptoms such as breathing, pulse, or abnormal color during puncture, stop the operation immediately and deal with it accordingly.
