The aim of this study was to investigate whether 5-hydroxytryptamine (serotonin, 5-HT) is involved in the mediation of sennoside-induced colonic fluid secretion and diarrhea. Oral administration of purified sennosides (25, 40 and 64 mg/kg) dose-dependently reversed net fluid absorption to net fluid
The effects of calcium polycarbophil (CP), a water-absorbing polymer, on bowel movement were examined in comparison with known laxatives and anti-diarrheal agents in dogs, a species that resembles humans for stool output. CP increased stool frequency, fecal water content and fecal weight in a
Senna and its main components sennosides are well-known effective laxative drugs and are used in the treatment of intestinal constipation in the world. Their potential side effects have attracted more attention in clinics but have little scientific justification. In this study, senna extract (SE),
Oral administration of sennosides (20-30 mg/kg) to fasted dogs has been shown to induce a strong and long-lasting inhibition of myoelectric colon activity which was evident after a delay of 6-10 h corresponding to oro-cecal transit and colonic metabolism and was accompanied by abundant diarrhea.
Daiokanzoto (DKT, combination of rhubarb and glycyrrhiza), a Kampo medicine, is clinically effective for constipation. Sennoside A is well known to induce diarrhea. Sennoside A is a prodrug that is transformed into an active metabolite, rheinanthrone, by intestinal bacteria. In this study, we
BACKGROUND
Constipation is a common and distressing condition in patients with cancer, especially those taking opioid analgesics. Many institutions prevent and treat constipation with titrated laxatives, which is known as a bowel protocol. An effective and well-tolerated bowel protocol is a very
The effects of sennosides on uterine motility were evaluated by electromyography in healthy adult ewes between day 70 and 120 of pregnancy to assess possible disturbances of the physiological pattern of contractility and eventual risks in pregnancy maintenance. At this stage of pregnancy, the ovine
BACKGROUND
Aquaporin-3 (AQP3) is expressed in mucosal epithelial cells in the colon and is important for regulating fecal water content. We examined the role of AQP3 in the laxative effect of rhubarb extract.
METHODS
After orally administering rhubarb extract or its major component (sennoside A) to
The pharmacological profile of DSP-6952, a novel 5-HT4 receptor partial agonist, was investigated to evaluate the potential use for GI disorders, and to compare its effects in some GI dysfunction models with those of clinically efficacious prokinetic agents. DSP-6952 enhanced gastric motility and
OBJECTIVE
To compare results of double balloon enteroscopy (DBE) procedures in pediatric and adult patients.
METHODS
The medical files of patients who underwent DBE at Gazi University School of Medicine, Ankara, Turkey between 2009 and 2011 were examined retrospectively. Adult and pediatric patients
Rheum tanguticum from the same area was divided into 8 types of variation according to the plant morphology, content differences of free anthraquinones, combined anthraquinones, double anthrone were studied. The results showed that the functional components of different variation types were
Daiokanzoto (DKT) exerts its laxative effect via colonic inflammation caused by sennoside A in Daio (rhubarb). Previously, we showed that the laxative effect of sennoside A is related to decreased aquaporin-3 (AQP3) expression in mucosal epithelial cells due to colonic inflammation. We also found
Irritable bowel syndrome (IBS) is a functional bowel disorder characterized by abdominal pain or discomfort and abnormal defecation. Polycarbophil calcium, a water-absorbing polymer, is expected to improve stool consistency. Polycarbophil calcium decalcified under the acidic condition and then
Sennoside A and B were detected in 21 commercial health tea products surveyed in 2000-2007, but there were 8 products in which the leaves could not be identified as senna because the leaves had become discolored. The results of assay of sennoside levels and TLC chromatograms suggested that processed
Cassia angustifolia Vahl (senna) is a natural product that contains sennosides, which are active components that affect the intestinal tract and induce diarrhea. Authors have shown that senna produces DNA (deoxyribonucleic acid) lesions in Escherichia coli cultures and can act as an antifungal
