Among the mechanisms which defend the body from infection with the virus of poliomyelitis is the meningeal-choroid plexus complex, which normally is capable of excluding the circulating virus from the central nervous organs. The complex plays a part also in preventing infection from virus present upon the nasal mucosa. Aseptic fluids which irritate, inflame, or even slightly alter the integrity...

conclusions our study showed that dexmedetomidine had better effects on sensory and motor block duration and motor block onset in comparison with ketorolac, as lidocaine adjuvants in infraclavicular brachial plexus block were present in both protocols. however, the first time to analgesic request by ketorolac was longer than dexmedetomidine. objectives the purpose of this study was to examine t...

The choroid plexus of the fourth ventricle consists of two symmetrical parts located in the roof of the ventricle and protruding through its openings, the foramina of Luschka and Magendie. The arteries supplying the choroid plexus of the fourth ventricle are difficult to approach because of their deep location within the cerebellopontine angles and the cerebellomedullary fissure. They originate...

The choroid plexus is a complex structure which hangs inside the ventricles of the brain and consists mainly of choroid plexus epithelial (CPE) cells surrounding fenestrated capillaries. These CPE cells not only form an anatomical barrier, called the blood-cerebrospinal fluid barrier (BCSFB), but also present an active interface between blood and cerebrospinal fluid (CSF). CPE cells perform ind...

To treat human immunodeficiency virus (HIV) within the CNS, levels of antiHIV drugs in the brain must reach therapeutic concentrations. The ability of (-)-2’-deoxy-3’-thiacytidine (3TC; lamivudine) to cross the blood-brain and blood-CSF barriers, alone and in combination with additional nucleoside analogues, was investigated. The bilateral in situ guinea-pig brain perfusion method, linked to HP...

beta-Amyloid (Abeta) concentration in the cerebrospinal fluid (CSF) of the brain may be regulated by the choroid plexus, which forms a barrier between blood and brain CSF. Abeta uptake from CSF was determined as its volume of distribution (V(D)) into isolated rat choroid plexus tissue. The V(D) of [125I]Abeta1-40 was corrected by subtraction of the V(D) of [14C]sucrose, a marker for extracellul...

Psychovegetal disturbances resulted in the aggravation of blood supply highest vegetal centers due to involvement pathologic process a. vertebralis and its sympathic plexus significantly affected manifestation cervical pain syndromes. Complex examination 124 patients with syndrome was performed study influence manual therapy. Clinical, neuro- orthopaedic, radiologic, miotonometric rheographic m...

OBJECTIVE Injuries of upper cervical spine are potentially fatal. Thus, appropriate diagnosis and treatment is essential. In our institute, preoperative computed tomography angiography (CTA) has been performed for evaluation of injuries of bony and vascular structure. The authors confirmed the engorged venous plexus within injured posterior neck muscle. We have this research to clarify the rela...

Abstract Background and aim Intracranial calcifications (ICs) occur when metals such as calcium or iron accumulate in blood vessels, glands other structures related to the brain. They can be physiological pathological. Currently, most sensitive method for imaging IC is cranial computed tomography (CT). The of this retrospective study was evaluate ICs co-existence them by CT. Patients methods 1,...
