This study presents a computer-based tool for three-dimensional (3D) visualization of the optic pathway and oculomotor system using 3D high-resolution magnetic resonance imaging (MRI) datasets from a healthy subject. The 3D models were built as wireframe grids co-registered with MRI sections. First, 3D anatomical models were generated of the visual pathway(More)
Adverse drug reactions (hepatotoxicity) are a frequent cause of acute liver injury with a wide clinical and histological spectrum. An early recognition of drug-related liver disease has been considered essential in clinical practice due to potential risks. In most cases exposure discontinuation improves the clinical picture.Steroids are used in a variety of(More)
Nitric oxide is an unconventional transmitter since it is not transported and released by exocytosis. In the pituitary gland, nitric oxide is locally synthesised by gonadotroph and folliculo-stellate cells. Dopamine, the principal central inhibitory signal in prolactin release, may exert its inhibitory effects by stimulation of nitric oxide production.(More)
In order to elucidate the existence of gender-related variations in both growth hormone (GH) release and the activity of somatotropic cells following bilateral adrenalectomy, a morphometric analysis was performed on GH-immunoreactive cells from adult male and female rats after bilateral adrenalectomy, correlating the findings with the serum levels of the(More)
BACKGROUND There is limited information on the long-term outcome in liver transplant (LT) subjects undergoing partial splenic embolization (PSE) prior to full dose pegylated interferon/ribavirin (peg-IFN/RBV). METHODS Retrospective review of eight LT subjects after PSE and antiviral therapy. RESULTS Baseline platelets and neutrophils were <50 000(More)
Interleukins are proteins involved in the immune system and have been related to the endocrine regulation of the hypothalamic-pituitary-adrenal axis as well as to the secretion of ACTH, prolactin (PRL), GH and, possibly, LH. Like interleukin-6 (IL-6), vasoactive intestinal peptide (VIP) is synthesized in the pituitary gland and stimulates prolactin(More)
A sialolith from a minor salivary gland of the mucosa of the upper lip was studied morphologically and analytically. Under stereoscopic microscopic visualisation, no core or any concentric laminar structure was found in the sialolith and it had a transparent glassy appearance. Scanning electron microscopy revealed differences between the internal structure(More)
Following administration of met-enkephalin into the third ventricle of rats of both sexes, an ultrastructural-morphometric study was carried out of the neural lobe of the hypophysis, comparing the results with those obtained in untreated animals, controls (injected intraventricularly with distilled water) and animals previously receiving naloxone(More)
