in this investigation the effects of excess vitamin a administration during the early embryonic period were studied. intramuscular injection of a single dose of 15000,20000 or 25000 iu/kg vitamin a to pregnant balb/c strain mice on either day 7,8,9 or 10 of gestation (vaginal plug= day 0 of gestation) produced major malformations in the central nervous system (cns) including exencephaly, hydroc...
the close relationship between the immune system and the central nervous system (cns) has been well-studied. the cns regulates almost all the functions of the immune system; however, the effect and/or the control of the immune system on the cns has not been well-studied yet. recent reports suggest that the cns has its own defence mechanism(s). in this review, attempts have been made to discuss ...
primary angiitis of the central nervous system (pacns) is an idiopathic disorder (vasculitis) restricted to the central nervous system (cns). it often presents with focal neurological deficits suggesting stroke or a combination of confusion and headache. we herein report three cases with various combinations of fever, partial seizure, encephalopathy, paresis, headache and ataxia. one of them wa...
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 mechanism...
Molecular genetic approaches in small model organisms like Drosophila have helped to elucidate fundamental principles of neuronal cell biology. Much less is understood about glial cells, although interest in using invertebrate preparations to define their in vivo functions has increased significantly in recent years. This review focuses on our current understanding of the three major neuron-ass...
This chapter provides an overview of the major stages of prenatal central nervous system (CNS) development. CNS development plays the central role in the primary argument of this book. That argument is that the prenatal CNS is particularly vulnerable to environmental perturbations because it is rapidly developing during that time period. Further, we argue that many of the learning and behaviora...
