1. NEUROPATOLOGIA DA CINOMOSE CANINA / NEUROPATHOLOGY OF CANINE DISTEMPER
Canine distemper is one of the most prevalent viral diseases of dogs. Several cases are diagnosed in a daily basis in private practices and veterinary hospitals around the country. Most cases of neurological manifestation of canine distemper are fatal and the diagnosis confirmation by histopathology is often necessary. Canine distemper encephalitis is the ma

2. Médula cervical como material para diagnóstico laboratorial da raiva. / Cervical spine as material for laboratory diagnosis of rabies.
Rabie is a neurotropic zoonosis infectum-contagious, whose persistence is mainly related to the street dogs, low immunity of the dog population and reduced adhesion to the laboratorial diagnosis, due to difficulty of collection and transport of the used material (brain). The cervical medulla can be considered the portion of the central nervous system of more

3. Examination of spinal cord in diseases of the craniocervical junction and high cervical spine.
A simple necropsy technique for the removal of the craniocervical junction was devised: a relatively small specimen comprising part of the clivus, the foramen magnum, and cervical vertebral canal is removed in one piece with the medulla and spinal cord inside, and examined systematically after fixation. This method, used in a series of patients with chronic

4. Evidence for descending tonic inhibition specifically affecting sympathetic pathways to the kidney in rats.
1. The present study investigated the possibility that pre- and postganglionic neurones innervating the kidney and spleen in rats are affected by descending inhibitory as well as descending excitatory influences. This hypothesis was tested by comparing the effects of cervical spinal cord transection to the effects of blockade of tonic activity of excitatory

5. Axonal projections from the rostral expiratory neurones of the Bötzinger complex to medulla and spinal cord in the cat.
Axonal projections of eighty-four rostral medullary expiratory neurones of the Bötzinger complex were tested using antidromic mapping techniques in anaesthetized cats. A projection to the ventral respiratory neurones of the medulla (n.r.a.) was shown in eleven out of twelve tested neurones. Also a spinal projection to the C5-C6 cervical segments was evident

6. Spontaneous corticospinal axonal plasticity and functional recovery after adult central nervous system injury
Although it is believed that little recovery occurs after adult mammalian spinal cord injury, in fact significant spontaneous functional improvement commonly occurs after spinal cord injury in humans. To investigate potential mechanisms underlying spontaneous recovery, lesions of defined components of the corticospinal motor pathway were made in adult r

7. Spontaneous haematomyelia: a necropsy study.
Spontaneous haematomyelia (intramedullary spinal haematoma), is an uncommon event. Predisposing conditions have been reported including syringomyelia, pregnancy and delivery, angioma, spinal artery aneurysm, and haemophilia, but only rarely has a pathological evaluation been performed. Two such cases studied at necropsy are reported. In one case, the haemato

8. The location of descending fibres to sympathetic neurons supplying the eye and sudomotor neurons supplying the head and neck.
Evidence is given of the location in man of the fibres going to the sympathetic neurons of the lateral horn that supply the intrinsic and extrinsic muscles of the eye and the sweat glands of the head and neck. For the region of the pons and medulla, the evidence is abstracted from the literature. For the cervical spinal cord, the evidence is from our cases o

9. Role of excitatory amino acids in the generation and transmission of respiratory drive in neonatal rat.
1. The involvement of excitatory amino acids in the generation and transmission of rhythmic respiratory drive was studied in an in vitro neonatal rat brain stem-spinal cord preparation. The subclasses of excitatory amino acid receptors studied included: (i) N-methyl-D-aspartate (NMDA) receptors, (ii) (R, S)-alpha-amino-3-hydroxy-5-methylisoxazole-4-propionic

10. Central hypoventilation as the presenting symptom in Hu associated paraneoplastic encephalomyelitis
Central hypoventilation is usually caused by ischaemic or neoplastic lesions of the medulla and upper cervical spinal cord. An autoimmune disorder is not usually considered in the differential diagnosis of this syndrome. We retrospectively identified 14 patients from our database of 202 patients with Hu antibodies who presented with brainstem symptoms. Three

11. Ventrolateral medullary neurones: effects on magnitude and rhythm of discharge of mesenteric and renal nerves in cats.
1. Discharge of whole mesenteric and renal nerves was recorded in eighteen chloralose-anaesthetized, artificially respired cats. 2. Inhibition of tonic activity of neurones within the rostral ventrolateral medulla (RVLM blockade) by bilateral application of glycine caused significant reductions in discharge of renal and mesenteric nerves, arterial blood pres

12. Noradrenergic modulation of the medullary respiratory rhythm generator in the newborn rat: an in vitro study.
1. Superfused brain stem-spinal cord preparations of newborn rats, which continue to show a rhythmic respiratory activity in vitro, were used to analyse the mechanisms whereby the A5 noradrenergic area modulates the activity of the medullary respiratory rhythm generator in the newborn. 2. In preparations including the pons (ponto-medullary preparations), nor
