Spinal trauma: pharmacological evidence for vasoconstrictor activity in cerebrospinal fluid.

Relationship between presence of vasoconstrictor activity in cerebrospinal fluid and time after subarachnoid haemorrhage from rupture of cerebral arterial aneurysms.

The relationship between clinical condition and vasoconstrictor factors in cerebrospinal fluid was studied in 19 patients for up to six weeks after subarachnoid haemorrhage. Vasoconstrictor activity was assayed biologically. Sixteen of 19 patients improved as vasoconstrictor activity declined; this pattern was not significantly influenced by surgery. Serial angiography was performed on three pa...

OBSTETRICS Effects of pre-eclampsia on maternal plasma, cerebrospinal fluid, and umbilical cord urotensin II concentrations: a pilot studyy

Background. Urotensin II (UII) is the most potent endogenous vasoconstrictor identified to date. Pre-eclampsia is associated with arteriolar vasospasm but the precise underlying mechanism is uncertain and we hypothesized that UII concentrations might also be elevated. In this study we measured UII concentrations in maternal plasma and cerebrospinal fluid (CSF), and umbilical vein plasma from pr...

Cerebrospinal Fluid and Spinal Anesthesia Parameters in Healthy Versus Opium-Addict Patients during Lower Limb Surgery

Complement and Its Component Fractions in Cerebrospinal Fluid in Inflammatory Cerebrospinal Diseases.

It is generally agreed that normal spinal fluid is entirely devoid of complement, but the reports of its presence in the spinal fluid in cerebrospinal diseases are contradictory. Complement was found in the spinal fluid of all cases of meningococcus meningitis by Ward and Fothergill (1), but was reported to be absent in the same diseases by others (24). Ward et al. (1, 5) found complement to be...

Neuroprotective effects of sildenafil in experimental spinal cord injury in rabbits.

Neuroprotective agents such as methylprednisolone and sildenafil may limit damage after spinal cord injury. We evaluated the effects of methylprednisolone and sildenafil on biochemical and histologic changes after spinal cord injury in a rabbit model. Female New Zealand rabbits (32 rabbits) were allocated to 4 equal groups: laminectomy only (sham control) or laminectomy and spinal trauma with n...
