lumbar puncture is one of the most common methods for assessment of central nervous system. allen is illustrating the role of nurses in relation to probable fears about this technique. question: what is lumbar puncture? answer: this technique is proper method that one needle and trocar enter to subarachnoid space in lumbar spine. this method is most common diagnostic test for central nervous sy...

conclusions post-vaccination encephalomyelitis is a very rare side effect of mencevax acwy. introduction post-vaccination encephalomyelitis is an inflammatory disorder of the central nervous system. it is triggered by certain vaccines. the diagnosis of post-vaccination encephalomyelitis depends on the close temporal relationship between vaccination and clinical presentation. case presentation w...

background: diabetes mellitus is associated with cognitive deficits in humans and animals. these deficits are paralleled by neurophysiological and structural changes in brain. in diabetic animals, impairments of spatial learning, memory, and cognition occur in association with distinct changes in hippocampus, a key brain area for many forms of learning and memory and are particularly sensitive ...

thalamic pain syndrome, a type of central post-stroke pain (cpsp), may develops after a hemorrhagic or ischemic stroke and results in impairment of the thalamus. there is limited experience about gabapentin in treatment of central pains like cpsp.in a prospective observational study, the intensity of pain was recorded using the numeric rating scale (nrs) at the entrance to the study. patients e...

conclusions considering that neuronal function highly depends on environmental conditions, any adverse alteration may affect the function and morphology of neurons. in this regard, our results showed the adverse effects of protein malnutrition on the morphology of the purkinje cells of cerebellum. results the low-protein group did not gain weight as much as control group (p < 0.05). the diamete...

During recent years, several investigators have used various silver-impregnation methods for the study of degenerating fibers and terminal endings in the central nervous system. Among them are: Miskolczy ('31, '34); Hoff ('32 a and b); Foerster et al ('33); Snider ('36); Gibson ('37 a and b); Rosiello ('37); Schimert ('38, '39); Szentagothai-Schimert ('41); Szentagothai ('42, '43, '48); Glees (...

A number of reduced silver methods have been used for the demonstration of degenerating axons and their terminations within the central nervous system. The present study is an attempt to evaluate the relative potentialities of the two methods which the authors have found most useful, namely the Gless and Nauta techniques. Much of the literature dealing with silver impregnation methods, as appli...

The last 140 years have seen considerable advances in knowledge of central nervous system tumors. However, the main tumor types had already been described during the early years of the twentieth century. The studies of Dr. Pío del Río Hortega have been ones of the most exhaustive histology and cytology-based studies of nervous system tumors. Río Hortega's work was performed using silver stainin...

Besides being a metabolite of nucleotides like ATP, adenosine is a mediator of neuronal function in the central nervous system. Its actions are mediated by at least three extracellular receptors. In this review different aspects of adenosine such as biosynthesis, release, inactivation and its receptors are discussed. It also covers pre- and postsynaptic effects as well as postreceptor mecha...
