Relationship between cerebrospinal fluid pressure changes and cerebral blood flow.
This study of the effects of certain drugs, gas mixtures, and other stimuli on the cerebrospinal fluid pressure corroborates previous conclusions that alterations in cerebral blood flow are reflected by similar changes in the cerebrospinal fluid pressure in the same direction. The hypothesis is advanced that the elevations and depressions in cerebrospinal fluid pressure resulting from these age...
متن کاملEffect of the calcium antagonist nimodipine on local cerebral blood flow: relationship to arterial blood pressure.
The effect of the calcium antagonist nimodipine on local CBF in 31 regions of the CNS was studied with the [14C]iodoantipyrine autoradiographic technique in lightly anaesthetised, mechanically ventilated rats. Continuous intravenous infusion of nimodipine (1, 2, or 4 micrograms kg-1 min-1) produced a dose-dependent reduction in MABP (reduced by 26 +/- 2% after 30 min of nimodipine, 4 micrograms...
متن کاملRaised intracranial pressure and cerebral blood flow. 4. Intracranial pressure gradients and regional cerebral blood flow.
Intracranial pressure was raised by expansion of a supratentorial subdural ballon in anaesthetized baboons. Pressures were measured at several sites, both supratentorial and infratentorial, and cerebral blood flow was measured in each cerebral hemisphere separately. Pressures recorded from the right and left lateral ventricles corresponded closely throughout. Highly significant correlations wer...
متن کاملThe role of stress on the rise of blood pressure
Background: The virtual rise of blood pressure resulted from stress, that is observed in subjects that are tested in medical centers, can be oftenly corrected by holter. This phenomenon causes such persons not to response to the common anti blood pressure treatments (2). Materials and methods: This descriptive study was conducted 2006-2007 at the heart clinic of Shohadaye–Ashayer hospital in Kh...
متن کاملassessment of the efficiency of s.p.g.c refineries using network dea
data envelopment analysis (dea) is a powerful tool for measuring relative efficiency of organizational units referred to as decision making units (dmus). in most cases dmus have network structures with internal linking activities. traditional dea models, however, consider dmus as black boxes with no regard to their linking activities and therefore do not provide decision makers with the reasons...
