1. Effects of dipyrone on the digestive tract
Dipyrone (metamizole), acting through its main metabolites 4-methyl-amino-antipyrine and 4-amino-antipyrine, has established analgesic, antipyretic, and spasmolytic pharmacological effects, which are mediated by poorly known mechanisms. In rats, intravenously administered dipyrone delays gastric emptying (GE) of liquids with the participation of capsaicin-se

2. Antidiarrheal effect of extract from the bark of Combretum leprosum in mice
Abstract This study investigated the effects of the ethanolic extract from the bark of Combretum leprosum (ECL) on intestinal transit and castor-oil induced diarrhea in mice. The oral administration of ECL (750 and 1000 mg/kg) slowed intestinal transit (ID50 of 455 mg/kg). The ECL (250-1000 mg/kg) reduced castor-oil induced diarrhea, in a time- and dose-depe

3. Solanum paniculatum root extract reduces diarrhea in rats
Abstract Solanum paniculatum L., Solanaceae, locally known as "jurubeba", is widely used in Brazil for culinary purposes, and in folk medicine to treat of diverse disorder including gastric dysfunctions. In this study we investigated the antidiarrheal activity of S. paniculatum roots extract in rats at different concentrations (125, 250 and 500 mg/kg, p.o) u

4. Contractile profile of esophageal and gastric fundus strips in experimental doxorubicin-induced esophageal atresia
Esophageal atresia (EA) is characterized by esophageal and gastric motility changes secondary to developmental and postsurgical damage. This study evaluated the in vitro contractile profile of the distal esophagus and gastric fundus in an experimental model of EA induced by doxorubicin (DOXO). Wistar pregnant rats received DOXO 2.2 mg/kg on the 8th and 9th g

5. 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

6. A hipovolemia por doaÃÃo de sangue aumenta a complacÃncia gÃstrica e eleva o limiar de saciedade em humanos sadios / Hipovelemia elicited by blood donation increases gastric compliance and satiety threshold in healthy volunteers
Objetivos: A hipovolemia aguda reduz o tÃnus e aumenta a complacÃncia gÃstrica em animais. A complacÃncia do estÃmago proximal à o principal determinante da saciedade no teste de saciedade (drinking test). No entanto, nÃo hà relatos de eventuais alteraÃÃes de complacÃncia, tÃnus, saciedade e de plenitude gÃstricas frente a uma reduÃÃo aguda do

7. 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

8. 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

9. 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/

10. 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
