چکیده

There are few data in the literature on the distribution of sodium between serum and cerebrospinal fluid. Mestrezat (1) determined the concentration of individual inorganic elements on a mixture of cerebrospinal fluid from twenty normal individuals and obtained a value of 322 mg. per 100 cc. for sodium. Pincus and Kramer (2) and Weston and Howard (3) have published short series of determinationsmade on samples of blood and spinal fluid taken at the same time. Pincus and Kramer state that the sodium concentration of spinal fluid is essentially the same as that of plasma although in nine out of eleven cases they found the same relationship that we consistently found, namely, slightly higher values for sodium in cerebrospinal fluid. Their figures in eleven instances average 331 mg. per 100 cc. for serum and 344 mg. per 100 cc. for cerebrospinal fluid. Weston and Howard in a series of twenty-seven cases of manic-depressive insanity obtained an average value-of 331 mg. per 100 cc. for both serum and cerebrospinal fluid, with a range of 297 to 343 mg. per 100 cc. in serum and 303 to 346 mg. per 100 cc. in cerebrospinal fluid. Leipold (4), quoted by Walter (5), gives values of 257 to 331 mg. of sodium per 100 cc. for spinal fluid and found the sodium value in the serum equal to that in the spinal fluid. Depisch and Richter-Quittner (6) have studied the inorganic elements in serum and cerebrospinal fluid. They have reported such extraordinary values, especially for calcium, as to cast serious doubt on the accuracy of the determinations reported.

Morphine in Plasma and Cerebrospinal Fluid of Patients Addicted to Opiates Undergoing Surgery: High-performance Liquid Chromatography Method

Background: The prevalence of opium addiction among Iranians is considerable. Since endogenous opioid systems may be altered as a consequence of addiction, it is very important to determine the plasma and cerebrospinal fluid (CSF) levels of morphine in Iranian patients addicted to opiates who will undergo surgery.Methods: We obtained CSF and plasma samples from 50 volunteers with an established...

Is there any Correlation between Cerebrospinal Fluid and Serum C-reactive Protein in Neonates Suspected to Meningitis?

Background: Meningitis is a common life threatening infection in neonatal period. Diagnostic value of CSF-CRP level in bacterial meningitis in children and adults has been studied worldwide, but there are limited studies on CSF-CRP in neonatal meningitis. This study conducted to assess any relation between CSF-CRP and plasma CRP levels and abnormal CSF findings in neonates suspected to meningit...
