1. DOES THE RHEUMATOID ARTHRITIS AFFECT THE ENTERIC NERVOUS SYSTEM?
RESUMO CONTEXTO: Poucos estudos sobre doenças artríticas têm sido realizados para verificar a presença de neurodegeneração. Diante do aumento do estresse oxidativo e dos efeitos extra-articulares da artrite reumatoide, estudos gastrointestinais devem ser investigados visando uma melhor compreensão dos efeitos sistêmicos da doença no sistema nervos

2. The role of ischemic preconditioning in the expression of apoptosis-related genes in a rat model of intestinal ischemia-reperfusion injury
Abstract Purpose: To analyze the effects of ischemic preconditioning (IPC) in the expression of apoptosis-related genes in rat small intestine subjected to ischemia and reperfusion. Methods: Thirty anesthetized rats underwent laparotomy and were drive into five groups: control (CG); ischemia (IG); ischemia and reperfusion (IRG); IPC and ischemia (IG+IPC)

3. Effect of acetylsalicylic acid on total myenteric neurons in mice experimentally infected with Trypanosoma cruzi
Abstract: We investigated the effects of acetylsalicylic acid (ASA) on the total myenteric neuronal population in the descending colon in Trypanosoma cruzi-infected mice. Thirty-five male Swiss mice, 60 days old, were divided into a control group (C group), control group treated with ASA (CA group), infected group (I group), and infected group treated with A

4. Combination vitamin C and vitamin E prevents enteric diabetic neuropathy in the small intestine in rats
The present study evaluated the effects of supplementation with a combination of vitamin C and vitamin E on NADH-diaphorase-positive (NADH-d+) and neuronal nitric oxide synthase (nNOS)-immunoreactive myenteric neurons in the duodenum and ileum in diabetic rats. Forty rats were distributed into the following groups: normoglycemic (N), normoglycemic supplement

5. 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

6. Administering ascorbic acid to rats undergoing ageing processes: effects on myosin-V immunoreactive myenteric neurons
Durante o processo de envelhecimento o Sistema Nervoso Entérico sofre alterações morfofuncionais, como a neurodegeneração entérica. A morte neuronal pode ser atribuída ao aumento de radicas livres, e o ácido ascórbico (AA), conhecido antioxidante, poderia minimizar danos causados pelo estresse oxidativo. O objetivo deste estudo é analisar o comport

7. Efeitos da isquemia/reperfusão intestinal sobre o receptor P2X2 e neurônios entéricos do íleo de ratos. / Effects of intestinal ischemia/reperfusion on P2X2 receptor and enteric neurons of the rats ileum.
The acute mesenteric ischemia is a vascular condition of extreme emergency, which is fatal in the world population by 60% to 80% of cases. The aim of this work was to study the effects of intestinal ischemia/reperfusion on the P2X2 receptor and different neuronal classes in the myenteric plexus. We analyzed the ileum of rats: control, Sham and ischemia/reper

8. Hypertrophy of NADH-diaphorase positive myenteric neurons in rat jejunum after acute infection caused by Toxoplasma gondii
Toxoplasmosis, a globally distributed feline-associated zoonosis caused by the protozoan Toxoplasma gondii, affects birds and mammals, including humans. This study assesses the consequences of acute T. gondii infection for NADH-diaphorase positive myenteric neurons in rat jejunum. Ten male Wistar rats (Rattus norvegicus) were divided into two groups: G1 (n =

9. Morfoquantitative and chemical coding analyses of the purinergic P2X2 receptor in myenteric plexus of female and male obese mice (ob/ob). / Análises morfoquantitativa e do código químico do receptor purinérgico P2X2 no plexo mioentérico do íleo de camundongos obesos fêmeas e machos (ob/ob).
The intestinal activities are coordinated by enteric nervous system, and dysfunctions in intestinal motility were observed in obese individuals. The enteric neurons have been demonstrated to express different purinergics receptors. This study aims to analyze the expression of P2X2 receptor and the chemical code in the myenteric neurons in obesity. Sample fro

10. Estudo do receptor P2X7 nas classes neuronais do íleo de ratos submetidos à isquemia intestinal com reperfusão. / Study of the P2X7 receptor in neurons of the ileum of rats subjected to intestinal ischemia with reperfusion.
Dor abdominal pode ser consequente a inúmeras causas, entre as várias possibilidades precisamos ficar atentos aos quadros de isquemia intestinal. No trato digestório a isquemia/reperfusão intestinal (I/R-i) acarreta alterações morfológicas nos neurônios entéricos. Este trabalho tem como objetivo analisar o comportamento das diferentes classes neuron

11. Morphological repercutions of burn injury components of the myenteric plexus in the jejunum of adults rats. / Repercussões morfológicas da lesão térmica corporal nos componentes do plexo mioentérico do jejuno de ratos adultos.
Burn is a determinant factor to alter body structures as the striated muscle. It also determines gastrintestinal mucosal atrophy what produce loss of selective barrier. With histochemical, immunohistochemical and light microscopy methods the myenteric plexus (MP) of the jejunum was evaluated in rats submitted to burn injury. The scalding was performed in 30%

12. Efeitos da alimentação com diferentes níveis calóricos nos neurônios mioentéricos do cólon de ratos Wistar durante o processo de envelhecimento / Effects of food with different caloric levels in myenteric neurons of the colon of rats during the aging process
Os últimos anos se caracterizaram pelo aumento significativo da população idosa mundial. Por esta razão, a preocupação com o idoso está se tornando uma constante em nossa sociedade, uma vez que o envelhecimento resulta em comprometimento das funções fisiológicas, acompanhado ou não de alterações estruturais. No trato gastrointestinal (TGI), o pr
