1. Sympathetic glial cells and macrophages develop different responses to Trypanosoma cruzi infection or lipopolysaccharide stimulation
Nitric oxide (NO) participates in neuronal lesions in the digestive form of Chagas disease and the proximity of parasitised glial cells and neurons in damaged myenteric ganglia is a frequent finding. Glial cells have crucial roles in many neuropathological situations and are potential sources of NO. Here, we investigate peripheral glial cell response to Tryp

2. ESTUDO DAS ALTERAÇÕES ELETROFISIOLÓGICAS DOS NEURÔNIOS DO GÂNGLIO CERVICAL SUPERIOR DE RATOS PRÉ-DIABÉTICOS / ELECTROPHYSIOLOGICAL STUDY OF THE CHANGES NEURONS OF THE RAT SUPERIOR CERVICAL GANGLIA PRE-DIABETES
Investigar as alterações eletrofisiológicas dos neurônios do gânglio cervical superior de animais pré-diabéticos torna-se extremamente relevante devido às alterações relacionadas à neuropatia diabética que ainda permanecem desconhecidas na literatura. Durante o desenvolvimento desse trabalho, ratos Wistar neonatos com idade entre 5 6 dias, foram

3. Anandamide injected into the lateral ventricle of the brain inhibits submandibular salivary secretion by attenuating parasympathetic neurotransmission
Our objective was to determine the effect of arachidonylethanolamide (anandamide, AEA) injected intracerebroventricularly (icv) into the lateral ventricle of the rat brain on submandibular gland (SMG) salivary secretion. Parasympathetic decentralization (PSD) produced by cutting the chorda tympani nerve strongly inhibited methacholine (MC)-induced salivary s

4. Efeitos do eugenol sobre variáveis elétricas de neurônios do gânglio cervical superior de ratos. / Effects of eugenol on electrical parameters of neurons superior cervical ganglion of rats.
Eugenol (EUG) is a fenilpropanoid obtained from the essential oils of plants such as clove and basil which has widespread use in dentistry on the sealing of the dental root cavity. EUG possesses, amongst others, an analgesic effect that may be due to a local anesthetic like inhibition of sodium currents, to a capsaicin like activation of TRPV-1 receptors or

5. Inhibition mechanism of the nicotinic acetylcholine receptor α3β4 tacrine / Mecanismos de inibição do receptor nicotínico de acetilcolina α3β4 pela tacrina
Neuronal nicotinic acetylcholine (cholinergic) receptors (nAChRs) are integral membrane proteins and belong to the family of ligand-gated cation channels composed by α and β subunits. These receptors play a key role in the signal transmission between neurons in the central and peripheral nervous system. The α3β4 subtype, for example, is t

6. Efeito do 1,8-cineol sobre os parâmetros eletrofisiológicos das células nervosas do gânglio cervical superior de ratos / Effect of 1,8-cineol on electrophysiological parameters of nerve cells in the rat superior cervical ganglion
1,8-cineol is a terpene that constitutes many essential oils from medicinal folk plants. This compound presents many pharmacological activities as anti-inflammatory, antitumoral and gastroprotective. However it is difficult to find studies that relate the effects of both essential oils and its compounds in nervous system tissues. Since many of these oils and

7. Resistance of peripheral autonomic neurons to in vivo productive infection by herpes simplex virus mutants deficient in thymidine kinase activity.
We used a model involving acute and latent herpes simplex virus (HSV) infections of mouse superior cervical ganglia to assess in vivo neuronal infections with two thymidine kinase-deficient (TK-) mutants of HSV type 1. Despite replication of the TK- HSV strains at the site of inoculation in the eyes, little if any viral replication occurred in the superior c

8. Demonstration of a neurotrophic factor for the maintenance of acetylcholinesterase and butyrylcholinesterase in the preganglionically denervated superior cervical ganglion of the cat.
Under sodium pentobarbital anesthesia, the superior cervical ganglia of cats were preganglionically denervated bilaterally. The following day cats were reanesthetized, the external carotid and lingual arteries were ligated bilaterally, and the right common carotid artery was infused for 24 hr with an extract prepared from cat brain, spinal cord, and sciatic

9. Effects of sodium pentobarbital anesthesia and neurotrophic factor on the maintenance of acetylcholinesterase and butyrylcholinesterase in the preganglionically denervated superior cervical ganglion of the cat.
In continuation of a previously reported study, the superior cervical ganglia of cats were preganglionically denervated bilaterally under sodium pentobarbital anesthesia. The following day cats were reanesthetized and infused via the common carotid artery with an aqueous extract of cat brain, spinal cord, and sciatic nerves for periods of 24, 12, 6, and 3 hr

10. Innervation of the palpebral conjunctiva and the superior tarsal muscle in the cynomolgous monkey: a retrograde fluorescent tracing study.
Retrograde fluorescent transport of Fast Blue (FB) and Diamidino Yellow (DY) was used to study the localisation of neurons that innervate the palpebral conjunctiva and the superior tarsal muscle in the cynomolgous monkey. Labelled cell bodies of sensory neurons including a few double labelled cell bodies were found in the ophthalmic part of the ipsilateral t

11. The permeability of the capsule of autonomic ganglia to horseradish peroxidase.
Horseradish peroxidase (HRP) was applied to the capsules of various autonomic ganglia in vivo. The capsules of the inferior mesenteric ganglion and superior cervical ganglion of guinea-pigs and the inferior mesenteric ganglion of mice were readily penetrated by the enzyme. The capsule of the mouse superior cervical ganglion was apparently impermeable to HRP,

12. Immunohistochemical demonstration of choline acetyltransferase-immunoreactive preganglionic nerve fibers in guinea pig autonomic ganglia.
The distribution of choline acetyltransferase (ChoAcTase)-like immunoreactivity in the superior cervical ganglion and the stellate ganglion was analyzed with immunohistochemistry. A dense network of ChoAcTase-immunoreactive nerve fibers was observed in both ganglia studied. The ChoAcTase-positive fibers were found in all parts of the ganglia but had a differ
