Computed tomography (CT) was used for diagnosis of brain abscess in a 6-month-old, Japanese black calf presented with neurological dysfunction, compulsive circling and vision disturbance. CT images showed asymmetric lateral ventricles, and presence of intra-cranial multiple low absorption lesions surrounded by capsule suggestive of abscess in the right cerebral hemisphere. Postmortem examinatio...

The effect of ventriculocisternal perfusion with mock CSF with alkaline or acidic pH on the local CMRglu (LCMRglu) in the caudatoputamen was studied in artificially ventilated and relaxed rats. In control rats both lateral cerebral ventricles were perfused with mock CSF at pH 7.4. In the experimental series one cerebral ventricle was infused with normal mock CSF while the other was infused with...

I. PAAKKARI, M.-L. NURMINEN and A.-L. SIREN, Cardioventilator effects of TRH in anaesthetized rats: rote of the brain stem, European J. Pharmacol. 122 (1986) 131-134. Cardioventilator responses were studied in anaesthetized rats after injections of TRH into either the lateral (i.c.v. lat) or the fourth (i.c.v. IV) cerebral ventricles. TRH induced a morerapid hypertensive effect i.c.v. IV than i...

ABSTRACT: Multiple congenital malformations can occur concomitantly in several species since the anomaly one organ may lead directly to malformation of another. Additionally, etiology is not always clarified. Choristoma refers an ectopic tissue that histologically normal abnormal location. A case pulmonary and nodal choristoma associated with cranioschisis, hydrocephalus, syringomyelia a new-bo...

Transgenic mice expressing a stabilized beta-catenin in neural precursors develop enlarged brains with increased cerebral cortical surface area and folds resembling sulci and gyri of higher mammals. Brains from transgenic animals have enlarged lateral ventricles lined with neuroepithelial precursor cells, reflecting an expansion of the precursor population. Compared with wild-type precursors, a...

Full-term infants with early-stage brain injuries from asphyxia were examined with two-dimensional ultrasound and color Doppler to assess the use of ultrasound in evaluating early brain injuries after neonatal asphyxia. The sonographic features of ultrasound and color Doppler were compared to those of magnetic resonance imaging (MRI). Ultrasound was used to monitor the brain parenchyma, lateral...

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...

Platelet-derived growth factor-C (PDGF-C) is one of three known ligands for the tyrosine kinase receptor PDGFRα. Analysis ofPdgfcnull mice has demonstrated roles for PDGF-C in palate closure and the formation of cerebral ventricles, but redundancy with other PDGFRα ligands might obscure additional functions. In search of further developmental roles for PDGF-C, we generated mice that were double...

Gradient-echo MR sequences are more sensitive to flow phenomena than spin-echo sequences are. We investigated aqueductal CSF flow by fast multiphase imaging. Fast multiphase imaging offers the opportunity to perform a dynamic study of fluid motion that is synchronous with the cardiac cycle. A section perpendicular to the cerebral aqueduct was imaged in 18 healthy volunteers. Serial, gated (ever...

Intracranial hemorrhage in hemophilia is an unusual manifestation of the disease. The cases hitherto reported have been those of subarachnoid rather than of intracerebral hemorrhage. Indeed, Gunther,2 writing in 1935, stated that no substantiated instance of cerebral hemorrhage in a hemophiliac had been detailed up to that date. Von Limbeck,5 however, is credited with the description of such a ...
