Cerebrospinal fluid pathways from cisterns to ventricles in N-butyl cyanoacrylate-induced hydrocephalic rats.

Object: Cerebrospinal fluid typically enters the subarachnoid space from the ventricles via the fourth ventricular foramina. However, there is clinical evidence that CSF also flows in the opposite direction. Ventricular reflux of CSF from a cistern is a well-known phenomenon in radioisotope studies in patients with normal-pressure hydrocephalus.

Development of an acute obstructive hydrocephalus model in rats using N-butyl cyanoacrylate.

Purpose: Previous animal models of obstructive hydrocephalus that was frequently combined with subarachnoid inflammation are not suitable for investigating cerebrospinal fluid (CSF) flow between ventricles and cisterns in obstructive hydrocephalus. In this study, we attempted to develop a new animal model for obstructive hydrocephalus in rats sparing subarachnoid space using N-butyl cyanoacrylate (NBCA).

Methods: Hydrocephalus was induced in adult male Sprague-Dawley rats with NBCA (n=15) or with kaolin (n=10).

Spontaneous pneumocephalus associated with pneumosinus dilatans.

The majority of cases of pneumocephalus are secondary to trauma or medical intervention. Spontaneous, non-traumatic pneumocephalus is an uncommon condition. Most cases of spontaneous pneumocephalus require surgery.

Repeated rupture of a middle meningeal artery aneurysm in moyamoya disease. Case report.

A case of moyamoya disease associated with subarachnoid hemorrhage and intracerebral hematoma resulting from repeated rupture of a middle meningeal artery aneurysm is reported. The aneurysm was progressively enlarged over a period of 1 month and was treated with middle meningeal artery embolization. The treatment method is discussed.

Segmental deformity correction after balloon kyphoplasty in the osteoporotic vertebral compression fracture.

Objective: Balloon kyphoplasty can effectively relieve the symptomatic pain and correct the segmental deformity of osteoporotic vertebral compression fractures. While many articles have reported on the effectiveness of the procedure, there has not been any research on the factors affecting the deformity correction. Here, we evaluated both the relationship between postoperative pain relief and restoration of the vertebral height, and segmental kyphosis, as well as the various factors affecting segmental deformity correction after balloon kyphoplasty.

Neuroprotective effect of ginseng total saponins in experimental traumatic brain injury.

In the present study, we investigated whether ginseng total saponins (GTSs) protect hippocampal neurons after experimental traumatic brain injury (TBI) in rats. A moderate-grade TBI was made with the aid of a controlled cortical impact (CCI) device set at a velocity of 3.0 m/sec, a deformation of 3.

Development of a rat model of graded contusive spinal cord injury using a pneumatic impact device.

An animal model of spinal cord trauma is essential for understanding the injury mechanisms, cord regeneration, and to aid the development of new therapeutic modalities. This study focused on the development of a graded experimental contusion model for spinal cord injury (SCI) using a pneumatic impact device made in Korea. A contusive injury was made to the dorsal aspect of the cord.

Evaluation of enzyme-linked immunosorbent assay in serological diagnosis of human neurocysticercosis using paired samples of serum and cerebrospinal fluid.

The applicability of micro-ELISA was evaluatd in human neuro-cysticercosis using paired samples of serum and CSF. A total of 355 cases who were mostly neurologic patients was subjected. Cystic fluid of C.

Fine Structure Of Cysticercus Celluosae From Human Brain.

A transmission electron microscopic study was conducted in order to know basic tegumental structure of Cysticercus cellulosae which was obtained from the ventricles of human brain. In general, the electron microscopic appearance of the tegument resembled that of the body wall of adult and larval forms of other cestodes. The tegument both of the parenchymatous portion (scolex and spiral canal) and bladder portion consisted of such components, i.
