Blood in the subarachnoid space.
Blood is a potent irritant to nervous tissue and alone can cause arachnoiditis. In combination with chemical substances, the risk is magnified. This was first noted in relation to oil-based myelographic dyes by Howland and Curry ( [1] ) who found that in dogs, blood and dye together caused severe adverse effects. Hence dural puncture during epidural administration of drugs should be treated ser...
متن کاملThe action and absorption of subarachnoid blood. I. Experimental hydrocephalus. II. Absorption of intact red blood cells from the subarachnoid space into the blood.
(I) Experimental Hydrocephaius: Repeated injections of autogenous blood components into the cisterna magna were given to adult rabbits. Only the whole blood, if injected more than three times, could cause the ventricular dilatation. Hydrocephalus was not produced in animals which received repeated injections of washed red blood cells, plasma or hemolysed red blood cells. However, the breakdown ...
متن کامل[Light and electron microscopic studies on the subdural space, the subarachnoid space and the arachnoid membrane].
Cranial meninges of humans were studied by electron microscopy after fixation in situ and histochemical demonstration of nicotinamide-adenine dinucleotide diaphorase within mitochon dria. There was an intimate fusion between the innermost portion of the dura mater (dural border cells) and the outermost portion of the arachnoid (arachnoid barrier layer). Cranial meninges did not contain a true s...
متن کاملsimulation and experimental studies for prediction mineral scale formation in oil field during mixing of injection and formation water
abstract: mineral scaling in oil and gas production equipment is one of the most important problem that occurs while water injection and it has been recognized to be a major operational problem. the incompatibility between injected and formation waters may result in inorganic scale precipitation in the equipment and reservoir and then reduction of oil production rate and water injection rate. ...
Experimental Subarachnoid Hemorrhage
Background and Purpose Cerebral vasospasm after subarachnoid hemorrhage may result partially from the imbalance between vasodilator and vasoconstrictor factors. The vasodilator peptides substance P and calcitonin gene-related peptide contained in the trigeminovascular system are involved in the vasomotor phenomenon occurring after subarachnoid hemorrhage. The delayed arterial narrowing may refl...
