13. Delayed Gastric Emptying of Semi-solid diets in Patients with Chagasic Megaesophagus
RESUMO OBJETIVO: Medir o tempo de esvaziamento gástrico de uma dieta semi-sólida em indivíduos com megaesôfago chagásico, em comparação com um grupo controle não-chagásico. MÉTODO: O tempo necessário para o esvaziamento gástrico de uma dieta semi-sólida foi avaliada por meio de ultrassonografia, em 28 pacientes com megaesôfago Chagásico (gra

14. Síndrome de estenose pilórica por adenocarcinoma de piloro
We present a case of primary malignant pylorus neoplasia, emphasizing its rarity, the difficulty of diagnosis and the importance of an adequate prepare before the endoscopic procedure. Literature shows that tumors compromising the first, third and fourth segments of duodenum are rare, especially those of the pyloric area, representing only 0.35% of all malig

15. Evidence for the involvement of peripheral β-adrenoceptors in delayed liquid gastric emptying induced by dipyrone, 4-aminoantipyrine, and antipyrine in rats
Dipyrone (Dp), 4-aminoantipyrine (AA), and antipyrine (At) delay liquid gastric emptying (GE) in rats. We evaluated adrenergic participation in this phenomenon in a study in male Wistar rats (250-300 g) pretreated subcutaneously with guanethidine (GUA), 100 mg·kg−1·day−1, or vehicle (V) for 2 days before experimental treatments. Other groups of animals

16. Gastric emptying of water in children with severe functional fecal retention
The objective of this study was to evaluate gastric emptying (GE) in pediatric patients with functional constipation. GE delay has been reported in adults with functional constipation. Gastric emptying studies were performed in 22 children with chronic constipation, fecal retention and fecal incontinence, while presenting fecal retention and after resuming r

17. Neural mechanisms involved in the delay of gastric emptying of liquids in rats induced by myocardial infarction recent / Mecanismos neurais envolvidos no retardo do esvaziamento gástrico de íiquidos em ratos induzido através do infarto recente do miocardio
O esvaziamento gástrico (EG) consiste na transferência ordenada do conteúdo do estômago para o duodeno, Situações patológicas como alterações hemodinâmicas modificam a velocidade do E.G. e função motora do trato gastrointestinal. O infarto do miocárdio determina retarde do E.G. em ratos, possivelmente pelo estresse causado pela ligadura da arté

18. Antiulcer mechanisms of chloroformic and ethyl acetate phases from aerial parts of Praxelis clematidea (Griseb.) R. M. King &H. Robinson (Asteraceae) / Mecanismos antiulcerogênicos das fases clorofórmica e acetato de etila obtidas das partes aéreas de Praxelis clematidea (Griseb.) R. M. King &H. Robinson (Asteraceae)
Praxelis clematidea (Griseb.) R. M. King &H. Robinson (Asteraceae) is a native herb to South America. The chloroformic phase from aerial parts of P. clematidea (CHCl3P-Pc) has hydroxylated and methoxylated flavones and it has shown gastroprotective activity. The ethyl acetate phase (AcOEtP-Pc) has hydroxylated flavonoids. So the gastroprotective activity of

19. CaracterizaÃÃo das vias neuro-humorais no retarde do esvaziamento gÃstrico de lÃquidos advindo da distensÃo mecÃnica atrial direita em ratos acordados. / Characterization of neuro-humoral pathways involved in delayed gastric emptying of liquids due to mechanical right atrial stretch in awake rats.
Right atrium mechanical stretch (AS) increases gastric motility in anesthetized rats. We aimed to study the effect of AS on gastric emptying (GE) in awake rats and the related neuro-humoral pathways ivolved. Male albino rats (N=361, 250-280g) had a silicone balloon inserted in the right atrium. After 24-h, the central venous pressure (CVP), heart rate (HR) a

20. Efeitos da hipervolemia crÃnica sobre a motilidade gastrintestinal e transporte intestinal de Ãgua e eletrÃlitos em ratos sob nefrectomia parcial / Effects of chronic hypervolemia on gastrointestinal motility and intestinal transport of water and electrolytes in rats under partial nephrectomy
Està bem estabelecido que a regulaÃÃo dos lÃquidos corporais seja garantida pela interaÃÃo funcional entre os sistemas cardiovascular e renal. Atualmente, evidÃncias clÃnicas e experimentais sugerem que o trato gastrintestinal (TGI) ajusta seu padrÃo motor e absortivo apÃs variaÃÃes agudas da volemia. Embora a insuficiÃncia renal parcial ou tota

21. Efeitos gastroprotetor e procinÃtico do sulfeto de hidrogÃnio (H2S) em camundongos - papel dos neurÃnios aferentes sensÃveis a capsaicina, receptores vanilÃides do tipo 1 (TRPV1) e canais de k atp-depedentes (KATP). / Gastroprotect and prokinetic effect of hydrogen sulphide (H2S) in mice: role of capsaicin-sensitive afferent neurons, vanilloid receptors type 1 (TRPV1) and K ATP-dependent channels (KATP).
INTRODUÃÃO: Recentemente, foi demonstrado que o H2S està envolvido em inÃmeras funÃÃes fisiolÃgicas e patolÃgicas, sendo produzido em muitos tecidos de mamÃferos. OBJETIVOS: Avaliar o papel do H2S na defesa da mucosa e no controle da motilidade gÃstrica em camundongos, bem como estudar a participaÃÃo dos canais de KATP, dos neurÃnios sensoriais

22. Phenylpyrazolone derivatives inhibit gastric emptying in rats by a capsaicin-sensitive afferent pathway
Dipyrone (Dp), 4-aminoantipyrine (AA) and antipyrine (At) administered iv and Dp administered icv delay gastric emptying (GE) in rats. The participation of capsaicin (Cps)-sensitive afferent fibers in this phenomenon was evaluated. Male Wistar rats were pretreated sc with Cps (50 mg/kg) or vehicle between the first and second day of life and both groups were

23. Vincristine delays gastric emptying and gastrointestinal transit of liquid in awake rats
We evaluated the effects of vincristine on the gastrointestinal (GI) motility of awake rats and correlated them with the course of vincristine-induced peripheral neuropathy. Vincristine or saline was injected into the tail vein of male Wistar rats (180-250 g) on alternate days: 50 µg/kg (5 doses, N = 10), 100 µg/kg (2, 3, 4 and 5 doses, N = 49) or 150 µg/

24. Gastric emptying of a liquid meal in children with severe functional constipation, fecal impaction and soiling / Esvaziamento gastrico de refeição liquida em crianças com constipação cronica funcional grave, com impactação fecal e escapes fecais retentivos
Gastrointestinal motility disorders may be at the basis of constipation. Gastric emptying delay has been reported in constipated patients and a causality relation is still not outlined. The objective of this study was to evaluate pre- and post-treatment gastric emptying values and dyspeptic symptoms in a group of children with functional constipation and fec
