    Based on chemotaxonomy, we decided to investigate the possible antidiarrheal activity in mice of a crude ethanolic extract obtained from aerial parts of Croton grewioides (CG-EtOH). We tested for any possible toxicity in rat erythrocytes and acute toxicity in mice. Antidiarrheal activity was assessed by determining the effect of CG-EtOH on defecation frequency, liquid stool, intestinal motility and intestinal fluid accumulation. CG-EtOH showed no in vitro cytotoxicity and was not orally lethal. In contrast, the extract given intraperitoneally (at 2000 mg/kg) was lethal, but only in females. CG-EtOH produced a significant and equipotent antidiarrheal activity, both in defecation frequency (ED50 = 106.0 ± 8.1 mg/kg) and liquid stools (ED50 = 105.0 ± 9.2 mg/kg). However, CG-EtOH (125 mg/kg) decreased intestinal motility by only 22.7% ± 4.4%. Moreover, extract markedly inhibited the castor oil-induced intestinal contents (ED50 = 34.6 ± 5.4 mg/kg). We thus conclude that CG-EtOH is not orally lethal and contains active principles with antidiarrheal activity, and this effect seems to involve mostly changes in intestinal secretion. SUMMARY CG-EtOH showed no in vitro cytotoxicity and was not orally lethal. In contrast, the extract given intraperitoneally (at 2000 mg/kg) was lethal, but only in females.CG-EtOH probably contains active metabolites with antidiarrheal activity.CG-EtOH reduced the frequency and number of liquid stools.Metabolites presents in the CG-EtOH act mainly by reducing intestinal fluid and, to a lesser extent, reducing intestinal motility. Abbreviations Used: CG-EtOH: crude ethanolic extract obtained from the aerial parts of C. grewioides; WHO: World Health Organization; ED50: dose of a drug that produces 50% of its maximum effect; Emax: maximum effect PMID:27365990

    Full Text Available The antidiarrheal effects of chloroform, methanol, and aqueous extracts of Bidens odorata Cav. were investigated at doses of 200 mg/kg on castor-oil-induced diarrhea. The chloroform extract of B. odorata (CBO reduced diarrhea by 72.72%. The effect of CBO was evaluated on mice with diarrhea induced by castor oil, MgSO4, arachidonic acid, or prostaglandin E2. CBO inhibited the contraction induced by carbachol chloride on ileum (100 µg/mL and intestinal transit (200 mg/kg in Wistar rats. The active fraction of CBO (F4 at doses of 100 mg/kg inhibited the diarrhea induced by castor oil (90.1% or arachidonic acid (72.9% but did not inhibit the diarrhea induced by PGE2. The active fraction of F4 (FR5 only was tested on diarrhea induced with castor oil and inhibited this diarrhea by 92.1%. The compositions of F4 and FR5 were determined by GC-MS, and oleic, palmitic, linoleic, and stearic acids were found. F4 and a mixture of the four fatty acids inhibited diarrhea at doses of 100 mg/kg (90.1% and 70.6%, resp.. The results of this study show that B. odorata has antidiarrheal effects, as is claimed by folk medicine, and could possibly be used for the production of a phytomedicine.

    The objective of this study was to evaluate the pharmacological mechanisms involved in anti-inflammatory and antidiarrheal actions of hydroalcoholic extract obtained from the leaves of Cissus sicyoides (HECS). The anti-inflammatory effect was evaluated by oral administration of HECS against acute model of edema induced by xylene, and the mechanisms of action were analysed by involvement of arachidonic acid (AA) and prostaglandin E2 (PGE2). The antidiarrheal effect of HECS was observed and we analyzed the motility and accumulation of intestinal fluid. We also analyzed the antidiarrheal mechanisms of action of HECS by evaluating the role of the opioid receptor, α2 adrenergic receptor, muscarinic receptor, nitric oxide (NO) and PGE2. The oral administration of HECS inhibited the edema induced by xylene and AA and was also able to significantly decrease the levels of PGE2. The extract also exhibited significant anti-diarrheal activity by reducing motility and intestinal fluid accumulation. This extract significantly reduced intestinal transit stimulated by muscarinic agonist and intestinal secretion induced by PGE2. Our data demonstrate that the mechanism of action involved in the anti-inflammatory effect of HECS is related to PGE2. The antidiarrheal effect of this extract may be mediated by inhibition of contraction by acting on the intestinal smooth muscle and/or intestinal transit. PMID:26805827

    Diarrhea is a serious problem affecting 3-5 billion people per year around the world, especially children of below 5 years. 70% of the world population uses traditional and indigenous medicine for their primary health care. The facts of these indigenous remedies are passed verbally and sometimes as documents. Since ancient time, Ayurveda is the main system of healing in South East Asian countries. Indian literature from ayurvedic texts and other books claim the potency of several plants in the treatment of diarrhea. As the global prospective of ayurvedic medicine is increasing, interest regarding the scientific basis of their action is parallely increasing. Researchers are doing experiments to establish the relation between the claimed action and observed pharmacological activities. In the present article, an attempt was made to compile the scientific basis of medicinal plants used to cure diarrhea in Ayurveda. Literature was collected via electronic search (PubMed, ScienceDirect, Medline, and Google Scholar) from published articles that reports antidiarrheal activity of plants that were mentioned in Ayurveda classics. A total of 109 plant species belonging to 58 families were reported for their antidiarrheal activity. Several Indian medicinal plants have demonstrated promising antidiarrheal effects, but the studies on the antidiarrheal potentials of these plants are not taken beyond proof of concept stage. It is hoped that the article would stimulate future clinical studies because of the paucity of knowledge in this area.

    Isovanillin and iso-acetovanillon are two phenolic components isolated from a number of plants including Pycnocycla spinosa. P. spinosa extract has antispasmodic and antidiarrheal activities. However, no comparative study has been done on antidiarrheal action of isovanillin and iso- acetovanillon, so far. The aim of this study was to investigate antidiarrheal action of isovanillin and iso-acetovanillon and their effects on small intestinal transit, for comparison with propantheline. Male mice (25-30 g), fasted over night with free access to water, were treated with test compounds or control (p.o.). Thirty min later castor oil (0.5 ml) was given orally to the animals. In another groups of animals MgSO4 (0.5 ml of 10% solution) was given first and half an hour later the test drugs were administered. Onset and number of wet defecations were recorded for each animal over 3.5 h after treatment with diarrhoea inducing agents. In another groups, intestinal transit of charcoal meal was determined following administration of the compounds. Isovanillin (2 mg/kg & 5 mg/kg), iso-acetovanillon (2 mg/kg & 5 mg/kg) and P. spinosa extract (5 mg/kg) delayed onset of diarrhoea and significantly reduced wet defecation induced by castor oil and MgSO4. They all had antidiarrheal effect similar to propantheline (5 mg/kg). Isovanillin, iso-acetovanillon and P. spinosa extract compared to control groups, significantly reduced small intestinal transit of charcoal meal. This study shows that antidiarrheal effect of P. spinosa extract is at least partially due to presence of two active compounds isovanillin and iso-acetovanillon.

    Objective:To evaluate antidiarrheal activity of the fractions of aqueous extract from stem barks of Thespesia populnea (Malvaceae). Methods:From the aqueous extract three fractions namely ethyl acetate fraction (EAF), methanolic fraction (MF) and residue fraction (RF) were made and studied for antidiarrheal activity. Antidiarrheal activity of the fractions were evaluated in castor oil induced diarrhea, prostaglandin E2 (PG-E2) induced diarrhea and charcoal meal test as in vivo models and the most potent fraction was further evaluated with in vitro models to determine the possible antimotility effect. Results:In castor oil induced diarrhea model, the RF (10, 25, 50 and 100 mg/kg, po.) and MF (100 mg/kg, po.) has significantly reduced the cumulative wet faecal mass, where as the EAF have not shown any significant antidiarrheal activity, RF was found to be more potent than MF. Based on these results and percentage yield, only RF was evaluated in PG-E2 induced enteropooling and charcoal meal test. RF (10, 25 and 50 mg/kg) had shown significant inhibition of PG-E2 induced secretions (antisecretory) and decreased the movement of charcoal in charcoal meal test indicating its antimotility activity. Furthermore, RF has showed significant inhibition of acetylcholine, histamine and BaCl2 induced contractions on rat colon, guinea pig ileum and rabbit jejunum with EC50 values of 241.7, 303.1 and 286.1μg/mL, respectively indicating the antimotility effect of RF. The phytochemical analysis of RF showed presence of gums and mucilages and the possible mechanism may be the combination inhibition of elevated prostaglandin biosynthesis and reduced propulsive movement of the intestine. Conclusions:RF possesses good antidiarrheal activity comparing with other two fractions and the possible mechanism thought to be associated with combination of antisecretory and antimolity.

    Full Text Available Summary: The anti-diarrheal effect of methanol extract (ME of seeds of Monodora tenuifolia Benth (Annonaceae, a wildly growing orchid flowering tree whose seed is traditionally used as antidiarrhea remedy, was studied using rodent models of diarrhea, enteropooling and gastrointestinal motility induced by castor oil. Acute toxicity and lethality (LD50 and phytochemical constituents of ME were also evaluated. The results showed that ME significantly (P<0.05 reduced the watery texture and number of fecal droppings over 4 h. It also significantly (P<0.05 reduced the volume and weight of intestinal content in a non-dose-related manner. On gastro-intestinal motility, ME significantly (P<0.05 reduced the small intestinal transit of charcoal meal in mice induced by castor oil in a non-dose-related manner. Phytochemical analysis showed that ME tested positive to carbohydrates, saponins, proteins, resins, flavonoids, alkaloids, terpenoids, steroids, fats and oil. Acute toxicity and lethality studies on ME revealed an oral LD50 greater than 5000 mg/kg in mice. These results showed that seeds of M. tenuifolia possess anti-diarrheal properties mediated through inhibition of hyper-secretion and gastrointestinal motility which substantiate the use in the treatment of diarrhea in traditional medicine. Industrial relevance: The industrial relevance of findings from this study derives from the possibility of formulating the powdered seed of this plant or its alcohol extract, into a herbal anti-diarrhea remedy. From this study and the age long use as condiment, toxicity may not preclude use as a medicament.

    Full Text Available Tinospora cordifolia is indigenous to the tropical areas of India, Myanmar and Sri Lanka. The use of plant as remedy for diarrhea and ulcer is well-documented in Ayurvedic system of medicine. However, pharmacological evidence does not exist to substantiate its therapeutic efficacy for the same. The aim was to investigate the antidiarrheal and antiulcer activity of ethanolic and aqueous extracts of T. cordifolia in rats. The antidiarrheal activity of T. cordifolia extracts was evaluated by castor oil and magnesium sulfate-induced diarrhea using parameters such as onset of diarrhea, number of wet stools, total number of stool and weight of total number of stools. The antiulcer activity of extracts was investigated using ethanol and pylorus ligation-induced ulcer. Furthermore, tissue antioxidant parameters such as reduced glutathione, catalase activity and lipid peroxidation level were also investigated. Tinospora cordifolia extracts were more efficacious in reducing number of total stools in both the models of diarrhea and showed a dose-dependent antidiarrheal effect. The antiulcer activity of the extracts was confirmed by a reduction in ulcer index along with the decrease in gastric volume, total acidity, and an increase in pH of gastric content in both the models. The obtained results have established a pharmacological evidence for the folkloric use of the T. cordifolia as antidiarrhoeal and antiulcer agent.

The objective of this study was to provide a scientific basis for the ethnopharmacological utility of this plant whose aqueous leaf and shoot extract was evaluated for acute toxicity and antidiarrheal activity using a murine model. Materials and methods Acute toxicity of the aqueous leaf and shoot extract was assessed after determining the major phytochemicals present in the extract. The aqueous leaf and shoot extract was assayed against castor oil-induced diarrhea, transit time, and enteropooling, in comparison to loperamide, a standard drug. Results The oral LD50 value obtained for Priva adhaerens aqueous extract was greater than 5000 mg/kg in rats; the aqueous leaf and shoot extract possessed several important phytochemicals. Furthermore, the aqueous extract significantly, and dose-dependently, reduced frequency of stooling in castor oil-induced diarrhea, intestinal motility, and castor oil-induced enteropooling in rats. Conclusion This murine model shows that it is relatively safe to orally use the aqueous leaf and shoot extract of Priva adhaerens . The aqueous extract contains phytochemicals that are active for the treatment of diarrhea in a rat model. PMID:25304198

    Full Text Available Enterotoxigenic Escherichia coli (ETEC produces two types of enterotoxins: heat-labile (LT and heat-stable (STa and STb. These molecules are involved in the induction of secretory diarrhea in animals including humans. This condition is currently treated using a fluid replacement therapy and antibiotics. This treatment is often not available to people in developing countries, and several die from the condition provoke by ETEC. Over the years, plants and plant extracts have been use as traditional medicine to treat various gastrointestinal ailments including diarrhea. Many of these plant products have been claimed to be active against diarrhea, however few have been extensively studied. The main objective of this review was to gather the scattered information on the antidiarrheal activities reported for various plant products on ETEC. This includes two major effects: (1 The inhibitory effect on bacterial growth or viability and (2 The interference with ETEC enterotoxins activity upon the intestinal epithelium. We will focus on plant products and extracts for which we have major indications of their biological activity against ETEC and their enterotoxins. Because Vibrio cholerae toxin (CT is structurally, antigenically and mechanistically related to LT, it will also be discussed in this review.

    Full Text Available Diarrhea is a serious public health problem in Mexico and other countries. A widely used alternative in the treatment of diarrhea is the use of herbal medicines. Infusions of chamomile and star anise possess anti-inflammatory and antimotility properties that could help alleviate gastrointestinal disorders. The aim of this study was to determine the effect of the mixture of chamomile and star anise infusions on gastrointestinal activity in mice. A gastrointestinal assessment of the mixture of chamomile and star anise was carried out in mice, and the percentage of advance of administered activated carbon through the intestinal tract of the animals was measured. Furthermore, the diarrhea model was induced with castor oil. The infusions were prepared using a mix with a 50:50 ratio of the herbs, and were administered at Mix-10, 20, 40 and 80 (mg/kg orally. The results indicate that Mix-40 and Mix-80 decreased the completion percentage of the activated carbon, delayed the appearance of diarrhea and decreased the number of evacuations in comparison with the control group. This suggests that the combination of chamomile and star anise can be used as an alternative antidiarrheal treatment.

    We investigated the laxative and anti-diarrheal activity of polycarbophil, an insoluble hydrophilic polymer, in comparison with other agents used for treating functional bowel disorder (FBD). In naive rats, polycarbophil (500 mg/kg) increased fecal weight and water contents without producing diarrhea. Carboxymethylcellulose (CMC) did not produce evident changes in bowel movement. Picosulfate markedly produced diarrhea. Loperamide, trimebutine and granisetron decreased stool output dose-dependently. Constipation, indicated by decrease in fecal weight, was produced by loperamide and clonidine in rats. Polycarbophil (500 mg/kg) and CMC increased fecal weight without diarrhea. Conversely trimebutine further decreased fecal weight in constipated rats. Polycarbophil (500 mg/kg) suppressed diarrhea induced by castor oil, and at 250-500 mg/kg, it produced shaped stools in animals with stools loosened by prostaglandin E2, serotonin or carbachol in mice. Polycarbophil (500 mg/kg) also reduced stools in rats with stool output increased by wrap restraint stress (WRS). CMC had no effect in the diarrhea models, except for carbachol-induced diarrhea, and WRS-induced evacuation. Loperamide, trimebutine and granisetron inhibited diarrhea production and WRS-induced evacuation, except for carbachol-induced diarrhea. The results show that polycarbophil prevents constipation and diarrhea without inducing diarrhea or constipation, which is different from the other agents. Hydrophilic polymers such as polycarbophil will be promising agents for the treatment of FBD.

  5. Fractionation of a herbal antidiarrheal medicine reveals eugenol as an inhibitor of Ca2+-Activated Cl- channel TMEM16A.

    Full Text Available The Ca(2+-activated Cl(- channel TMEM16A is involved in epithelial fluid secretion, smooth muscle contraction and neurosensory signaling. We identified a Thai herbal antidiarrheal formulation that inhibited TMEM16A Cl(- conductance. C18-reversed-phase HPLC fractionation of the herbal formulation revealed >98% of TMEM16A inhibition activity in one out of approximately 20 distinct peaks. The purified, active compound was identified as eugenol (4-allyl-2-methoxyphenol, the major component of clove oil. Eugenol fully inhibited TMEM16A Cl(- conductance with single-site IC(50~150 µM. Eugenol inhibition of TMEM16A in interstitial cells of Cajal produced strong inhibition of intestinal contraction in mouse ileal segments. TMEM16A Cl(- channel inhibition adds to the list of eugenol molecular targets and may account for some of its biological activities.

    Campomanesia adamantium (Myrtaceae) is a medicinal plant distributed in Brazilian Cerrado. Different parts of this plant are used in popular medicine for treatment of several diseases like fever, diarrhea, hypercholesterolemia and rheumatism. The aim of this work was to evaluate the inhibition of heat-stable enterotoxin type A (STa) by gallic acid present in the peel of C. adamantium fruit and assays to assess the antidiarrheal activity, anti-inflammatory and cytotoxic properties of peel extract using the T84 cell line model. The possible inhibition exerted by the gallic acid of the peel extract on the STa peptide was inferred by molecular dynamics simulations. The antidiarrheal effects were investigated measuring cGMP accumulation in cells after stimulation by STa toxin and antibacterial activity was assessed. The anti-inflammatory activity was assessed by inhibition of COX-1 and COX-2. MTT and LDH assays were used to evaluate any possible cytotoxic action while the CyQUANT test was used to investigate the effect on cell proliferation. A representation showing how the possible interactions between STa and the gallic acid of the extract might reduce the action of the enterotoxin is presented. C. adamantium peel extract significantly decreased the levels of cGMP in T84 cells. However, no effect on the species of microorganisms was observed. The extract also inhibited COX-1 (IC50 255.70 ± 0.04 ng/mL) and COX-2 (IC50 569.50 ± 0.11 ng/mL) enzymes. Cytotoxicity assay have shown significant changes in cells treated with the extract, which inhibited the cell proliferation until 72 hours of treatment. Direct interactions of phenolic compounds present in the extract with the STa toxin may limit its activity. Curative effect in the diarrhea treatment and its anti-inflammatory action is based on the pharmacological properties, mechanism of action of the C. adamantium peel extract, and no toxic effects of the peel extract presented on this work.

    Full Text Available Chemical investigation of the leaves from Ageratina glabrata yielded four new thymol derivatives, namely: 10-benzoyloxy-8,9-dehydro-6-hydroxythymol isobutyrate (4, 10-benzoyloxy-8,9-dehydrothymol (5, 10-benzoyloxythymol (6 and 10-benzoyloxy-6,8-dihydroxy-9-isobutyryl-oxythymol (7. In addition, (8S-10-benzoyloxy-8,9-epoxy-6-hydroxythymol isobutyrate (1, together with other two already known thymol derivatives identified as 10-benzoyloxy-8,9-epoxy-6-methoxythymol isobutyrate (2 and 10-benzoyloxy-8,9-epoxythymol isobutyrate (3 were also obtained. In this paper, we report the structures and complete assignments of the 1H and 13C-NMR data of compounds 1–7, and the absolute configuration for compound 1, unambiguously established by single crystal X-ray diffraction, and evaluation of the Flack parameter. The in vitro antiprotozoal assay showed that compound 1 and its derivative 1a were the most potent antiamoebic and antigiardial compounds. Both compounds showed selectivity and good antiamoebic activity comparable to emetine and metronidazole, respectively, two antiprotozoal drugs used as positive controls. In relation to anti-propulsive effect, compound 1 and 1a showed inhibitory activity, with activities comparable to quercetin and compound 9, two natural antipropulsive compounds used as positive controls. These data suggest that compound 1 may play an important role in antidiarrheal properties of Ageratina glabrata.

    Full Text Available The effectiveness of different types of rice in relation to their ability to accelerate diarrhea recovering was evaluated in a rat model of osmotic diarrhea (OD. Animals (90-100 g received protein free diet until reaching up to 20% weight loss, followed by lactose rich diet (LRD to induce osmotic diarrhea. Rats presenting osmotic diarrhea were divided into 4 groups, which received lactose rich diet for 4 days from 8 am to 8 pm, and one of three experimental products containing 6% rice flour differing in amylose content during the night: high (HA, intermediate (IA, and low (LA. A group fed stock diet containing equivalent amount of lactose was taken as control and allowed to recover spontaneously. Amylose and viscosity (cp at 25 °C, 10 rpm of final products were determined. Effectiveness was expressed as the ratio between percentages of normal vs. diarrheic stools during the treatment. Fecal characteristics in this rat model improved only as result of feeding high amylose content (HA type of rice. In this experimental model of osmotic diarrhea in young rats, the antidiarrheal effects of rice were strongly dependent on the type of diet used and appear to be related to its amylose content.Avaliou-se a eficiência de diferentes tipos de arroz quanto a sua habilidade de acelerar a recuperação de um episódio de diarreia em um modelo de indução de diarreia osmótica (DO em ratos.

    2015-09-01

    Full Text Available Morbidity and mortality from acute diarrheal disease remains high, particularly in developing countries and in cases of natural or man-made disasters. Previous work has shown that the small molecule clotrimazole inhibits intestinal Cl- secretion by blocking both cyclic nucleotide- and Ca(2+-gated K(+ channels, implicating its use in the treatment of diarrhea of diverse etiologies. Clotrimazole, however, might also inhibit transporters that mediate the inwardly directed electrochemical potential for Na(+-dependent solute absorption, which would undermine its clinical application. Here we test this possibility by examining the effects of clotrimazole on Na(+-coupled glucose uptake.Short-circuit currents (Isc following administration of glucose and secretagogues were studied in clotrimazole-treated jejunal sections of mouse intestine mounted in Ussing chambers.Treatment of small intestinal tissue with clotrimazole inhibited the Cl- secretory currents that resulted from challenge with the cAMP-agonist vasoactive intestinal peptide (VIP or Ca(2+-agonist carbachol in a dose-dependent fashion. A dose of 30 μM was effective in significantly reducing the Isc response to VIP and carbachol by 50% and 72%, respectively. At this dose, uptake of glucose was only marginally affected (decreased by 14%, p = 0.37. There was no measurable effect on SGLT1-mediated sugar transport, as uptake of SGLT1-restricted 3-O-methyl glucose was equivalent between clotrimazole-treated and untreated tissue (98% vs. 100%, p = 0.90.Treatment of intestinal tissue with clotrimazole significantly reduced secretory responses caused by both cAMP- and Ca(2+-dependent agonists as expected, but did not affect Na(+-coupled glucose absorption. Clotrimazole could thus be used in conjunction with oral rehydration solution as a low-cost, auxiliary treatment of acute secretory diarrheas.

    Full Text Available Type 2 diabetes mellitus (T2DM and dysglycemia (impaired glucose tolerance and/or impaired fasting glucose are increasingly contributing to the global burden of disease. Despite the continued introduction of hypoglycemic drugs, intervention in diabetes and its related complications remains a major global medical problem. Traditional Chinese medicine offers a number of potential candidates for developing hypoglycemic drugs. Berberine (BER, an isoquinoline alkaloid extract, has been commonly used as an oral drug to treat gastroenteritis and diarrhea for more than 1400 years. Although the antidiabetic effect of berberine has been noted in diabetic patients and demonstrated diabetic animal models in the last decade, its use is not yet accepted in the general medical community, for two reasons: its mechanism of action remains to be determined, and its bioavailability is low. Therefore, characterization of its mechanism of action and enhancement of its bioavailability are most important and the subject of current investigations. Recent studies have also revealed beneficial effects of berberine on diabetic complications. In this review the antidiabetic mechanism of action of berberine, its effect on diabetic complications, and efforts to improve its bioavailability are summarized. These studies may lead to its wider use for the treatment of type 2 diabetes mellitus and its complications.

    In this phyto-pharmacological screening of Pistia stratiotes L leaf and root extracts each separately in two different solvents demonstrated its potential medicinal value. Apparent antioxidant value is demonstrated by DPPH, Nitric oxide scavenging and Ferric ion reducing method. Additionally, total flavonoid and phenolic compounds were measured. The leaf methanolic extract scavenged both nitric oxide (NO) and DPPH radical with a dose dependent manner. But the pet ether fraction of root was found to have highest efficacy in Fe(3±) reducing power assay. Flavonoid was found to contain highest in the pet ether fraction of root (411.35mg/g) in terms of quercetin equivalent, similarly highest amount (34.96mg/g) of total phenolic compounds (assayed as gallic acid equivalents) were found to contain in the same fraction. The methanolic fractions appeared less cytotoxic compared to pet ether extracts. The plant extracts caused a dose dependent decrease in faecal droppings in both castor oil and magnesium sulphate induced diarrhea, where as leaf extracts in each solvent appeared most effective. Also, the plant extracts showed anthelmintic activity in earthworm by inducing paralysis and death in a dose dependent manner. At highest doses (50 mg/ml) all fractions were almost effective as the positive control piperazine citrate (10 mg/ml). Thus, besides this cytotoxic effect it's traditional claim for therapeutic use can never be overlooked.

    The present study was undertaken to determine whether total and methanol juice extracts of two Tunisian Pomegranate (Punica granatum L.) varieties (Garsi and Gabsi) protect against diarrhea as well as their effects on gastrointestinal transit (GIT) in healthy rats. In this respect, male Wistar rats were used and divided into control- and pomegranate-treated groups. The antidiarrheal activity was evaluated using the castor oil-induced diarrhea method and the GIT was assessed using charcoal meal. Our results showed that total and methanol P. granatum juice extracts produced a significant dose-dependent protection against castor oil-induced diarrhea. Pomegranate extracts and juice also decreased the GIT significantly and dose dependently. Importantly, the Garsi variety appeared to be more effective than the Gabsi variety on these two parameters. These findings suggest that pomegranate extracts have a potent antidiarrheal property in rats confirming their efficiency in the Tunisian traditional medicine.

    Diarrheal disease is one of the most important worldwide health problems. Enterotoxigenic Escherichia coli (ETEC) is the most frequently isolated enteropathogen in diarrheal diseases. In developing countries, a very large number of people, especially children, suffer from diarrhea. To combat this problem, World Health Organization has constituted the Diarrhea Diseases Control Program which guides studies on traditional medicinal practices and preventive measures. Gusuibu, a traditional folk medicine, has been claimed to heal certain types of diarrhea. However, so far no scientific study has been carried out on the anti-diarrheal mechanism of Gusiubu. The present study was performed to examine the suppressive activities of ethanol extracts of six sources of folk medicinal ferns used as Gusuibu on heat-labile enterotoxin (LT)-induced diarrhea. Inhibitory effects of six sources were evaluated on the ETEC LT subunit B (LTB) and monosialotetrahexosylganglioside (GMI) interaction by GM1-enzyme linked immunosorbent assay and patent mouse gut assay. Our results indicated that Drynaria fortunei had no anti-diarrheal effect, while, among the remaining five folk medicinal ferns, four belonging to family Davalliaceae had significant abilities on both the blocking of LTB and GM1 interaction and the inhibition of LT-induced diarrhea. In conclusion, these findings suggested the potential application of Gusuibu as an anti-diarrheal remedy.

    Full Text Available 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 using different experimental models such as castor oil-induced diarrhea, enteropooling and gastrointestinal motility, determined by in vivo experimental models. The major compound of root extract was characterized as chlorogenic acid based in the IR, 1D and 2D NMR analysis. All the extract doses achieved antidiarrheal potency, as indicated by reduced weight of feces in castor oil-induced diarrhea, decreased intestinal motility and significantly inhibited castor oil-induced enteropooling compared to the vehicle group. The highest dose (500 mg/kg produced greater anti-motility effect and better reduction of enteropooling, similar to the reference drug Loperamide (5 mg/kg. Extract from S. paniculatum L. roots had antidiarrheal activity, as shown by the lower weight of the feces as well as decrease in the accumulation of intestinal fluid and slower transit, justifying the traditional use of plant for diarrhea.

    2015-08-01

    Full Text Available Inhibition of cystic fibrosis transmembrane conductance regulator (CFTR and Ca2+-activated Cl- channel (CaCC represents an attractive approach for the treatment of secretory diarrhea. The aim of the study is to investigate the molecular basis of the anti-diarrheal effect of traditional Chinese herbal anti-diarrheal medicine Bistortae rhizoma. Fluorescence quenching assay indicated that the 40% methanol /water fraction (D5 dose-dependently inhibited both CFTR and CaCC function in transfected Fischer rat thyroid (FRT cells. Ex vivo studies indicated that D5 inhibited both forskolin (FSK-activated CFTR current and CCh-induced CaCC current in rat colonic mucosa. In the mouse closed-loop model, intraluminal application of D5 (200 µg/mL significantly reduced cholera toxin-stimulated fluid secretion. In the intestinal motility model, D5 significantly delayed intestinal peristalsis in mice. Our research suggests that CFTR and CaCC-mediated intestinal epithelial Cl- secretion inhibiting and gastrointestinal motility delaying may account for the anti-diarrheal activity of B. rhizoma.

    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 dose-dependent manner, but did not induce diarrhea. Sennoside and carboxymethylcellulose sodium (CMC-Na) increased fecal water content and induced diarrhea at lower doses than that which enhanced stool frequency. Trimebutine decreased stool frequency, fecal weight and fecal water content, resulting in inhibition rather than stimulation of defecation. In sennoside-induced diarrhea, loperamide and CP improved stool consistency and this was accompanied by reduced fecal moisture and frequency of diarrhea. In contrast, CMC-Na aggravated stool consistency with increased fecal water content and frequency of diarrhea, and trimebutine had little noticeable effect apart from reducing fecal weight. Our results show that CP has both laxative and anti-diarrheal effects in dogs and differed from conventional laxatives and anti-diarrheal agents. CP may be a suitable agent for treatment of idiopathic constipation, secretory diarrhea and irritable bowel syndrome with alternating constipation and diarrhea and with either predominating in terms of less side effects such as diarrhea or constipation.

    Full Text Available Abstract: Entada scandens (E. scandens (family: Mimosaceae is a widely used medicinal plant has been traditionally used by the folklore medicinal practitioners of Bangladesh to treat pain, cancer, gastrointestinal disorders where antinociceptive, cytotoxic and anti-diarrheal medications are implicated. Therefore, phytochemical groups and antinociceptive, cytotoxic, and anti-diarrheal activities of ethanol extract of seed of E. scandens were investigated by using acetic acid induced writhing model in mice, brine shrimp lethality bioassay and castor oil induced diarrheal model in mice. Phytochemical study of the extract indicated the presence of alkaloids, glycosides, tannins, flavonoids and saponins. At the doses of 250 and 500 mg/kg body weight, the extract showed a significant antinociceptive activity showing 60.61 and 72.73% inhibition respectively (P<0.001 comparable to that produced by Diclofenac Na (80.30% used as standard drug.  The extract showed significant toxicity in the brine shrimp lethality bioassay (LC50: 20µg/ml & LC90: 80µg/ml. While evaluating anti-diarrheal activity, the extract inhibited the mean number of defecation which were 13.21% (P<0.01 and 22.64 % (P<0.001 at the doses of 250 and 500mg/kg respectively. The latent period for the extract treated group was (p<0.01 increased as compared to control group. In addition, antimicrobial study was carried out by disc diffusion assay, but no significant inhibition was found against Escherichia coli, Pseudomonas aureus, Plesiomonas shigelloides, Salmonella typhi, S. paratyphi, Shigella dysenteriae, S. flexneri, S. boydii, S. sonnei, Proteus vulgaris,  Enterococcus faecalis, Staphylococcus saprophyticus, S. aureus, S. epidermidis and Streptococcus pyogenes.

    Loperamide is a common over-the-counter antidiarrheal considered safe in a broad range of dosages and thought devoid of abuse potential. We describe the first case of a patient with loperamide dependence due to misuse of its opiate-like effects achieved by chronic massive oral ingestions. A 26-year-old man who was taking 800 mg of loperamide per day presented requesting detoxification referral. Loperamide has potential for euphoric effects and information on how to facilitate such effects is easily available. It is important for physicians to be aware of the potential for misuse of and dependence on loperamide, with symptoms mimicking opiate use.

    In the treatment of the irritable bowel syndrome, it is important to qualify unrealistic expectations with regard to treatment, at an early stage. The therapeutic spectrum encompasses establishment of good rapport between physician and patient, modification of life style, provision of good patient information, reassurance, coping strategies, and temporal restraints on medication. Depending on the leading symptoms, the latter may range from laxatives to probiotics, anticholinergics or spasmolytics, prokinetic and anti-diarrheal agents, to 5-HT3/HT4 receptor antagonists. In individual patients with frequently recurrent or permanent pain, the use of tricyclic antidepressants may be considered. Painkillers should be reserved for patients in whom other therapeutic strategies have failed.

    ABSTRACT Objective:To justify the folkloric use ofSwietenia mahagoni (S. mahagoni) seeds, 90% ethanolic extract and their aqueous and organic partitioning substances were evaluated for their possible antidiarrhoeal and antimicrobial potentialsin vivo. Methods: Crude ethanolic extract ofS. mahagoni seeds were subjected and partitioned into fractions using solvents at different polarity. Antimicrobial and antidiarrheal activities were evaluated and subsequently outcomes were corresponded with the conventional standard drugs. Results: The antidiarrheal activity was assessed using mouse model, where unfractionated ethanolic extract significantly reduced, the number, onset, rate and weight of diarrheal episodes. This fraction showed the limited number of defecation episodes of 27.0% and 40.9% at dose of 200 mg/kg and 400 mg/kg body weight respectively and reference drug, loperamide, showed 53% at a dose of 50 mg/kg. All extract fractions exhibited the significant potential to kill or subside the growth of known Gram-positive and Gram-negative bacteria. Conclusions: Ethanolic extract and their aqueous and organic fractious revealed the seeds ofS. mahagoni(Linn.) have the potential to be used as a remedy for diarrhea and known pathogenic microbes which ensured the folkloric use of the seeds ofS. mahagoni.

  14. Ricinoleic acid and loperamide have opposite motor effects in the small and large intestine of the cat.

    Wienbeck, M; Wallenfels, M; Kortenhaus, E

    1987-07-01

    The actions of laxatives and antidiarrheal agents in the gut are incompletely understood. Therefore, the effects of Na ricinoleate 10(-4)-10(-2) g/kg b. w. and of loperamide 10(-4) g/kg b. w. on myoelectric activity and marker propulsion were studied in the small and large intestine of 7 unanesthetized cats. Intraduodenal application of ricinoleate briefly increased and then decreased spike activity in the small intestine; marker transit was delayed (92 +/- 18 min vs. 55 +/- 14 min in controls). Ricinoleate also initiated spike complexes of 10-215 sec duration. Transit from the right to the left colon was sometimes accelerated and sometimes delayed. The number of uncoupled slow waves was increased to 278% of control. Loperamide accelerated small intestinal transit to 17 +/- 6 min and markedly delayed it in the colon. At the same time it caused a strong and prolonged rise in colonic spike activity. When ricinoleate and loperamide were given together, their effects almost compensated for each other. The resulting net effect was similar to the data in the control experiments. It is concluded that laxatives and antidiarrheal agents alter not only transit, but also myoelectric activity in the small and large intestine. The effects are largely in opposite direction. Loperamide may, therefore, antagonize motor effects of ricinoleate in the gut.

  15. Analysis and modeling of heat-labile enterotoxins of Escherichia coli suggests a novel space with insights into receptor preference.

    2015-01-01

    Features of heat-labile enterotoxins of Escherichia coli which make them fit to use as novel receptors for antidiarrheals are not completely explored. Data-set of 14 different serovars of enterotoxigenic Escherichia coli producing heat-labile toxins were taken from NCBI Genbank database and used in the study. Sequence analysis showed mutations in different subunits and also at their interface residues. As these toxins lack crystallography structures, homology modeling using Modeller 9.11 led to the structural approximation for the E. coli producing heat-labile toxins. Interaction of modeled toxin subunits with proanthocyanidin, an antidiarrheal showed several strong hydrogen bonding interactions at the cost of minimized energy. The hits were subsequently characterized by molecular dynamics simulation studies to monitor their binding stabilities. This study looks into novel space where the ligand can choose the receptor preference not as a whole but as an individual subunit. Mutation at interface residues and interaction among subunits along with the binding of ligand to individual subunits would help to design a non-toxic labile toxin and also to improve the therapeutics.

    2011-01-01

    Full Text Available Eugenia dysenterica is a plant typically found in the Cerrado biome and commonly used in popular medicine due to its pharmacological properties, which include antidiarrheal, skin healing, and antimicrobial activities. The effects of ethanolic extract, aqueous extract and infusion of E. dysenterica leaves on intestinal motility and antidiarrheal activity were evaluated using ricin oil-induced diarrhea in rats. At doses of 400 and 800 mg⋅Kg−1, the ethanolic extract decreased intestinal motility while the other extracts showed no significant effects. Moreover, serum levels of chloride, magnesium, and phosphorus were also measured in rats. Histopathologic and enzymatic analyses were also performed to investigate any toxic effect. Animals treated with infusion, ethanolic extract, ricin oil, and loperamide presented morphological alterations in the small intestine, such as mucosa lesion, epithelial layer damage, and partial loss and/or morphological change of villi. Furthermore, the liver showed congestion and hydropic degeneration. Serum levels of alanine aminotransferase increased significantly in all treatments, but none rose above reference values. In summary, our results suggest that compounds present in leaves of E. dysenterica may have therapeutic benefits on recovery from diarrhea despite their toxic effects.

    1999-01-01

    We documented 12 sites in the Yellowstone ecosystem where grizzly bears (Ursus arctos horribilis) had purposefully consumed soil (an activity known as geophagy). We also documented soil in numerous grizzly bear feces. Geophagy primarily occurred at sites barren of vegetation where surficial geology had been modified by geothermal activity. There was no evidence of ungulate use at most sites. Purposeful consumption of soil by bears peaked first from March to May and again from August to October, synchronous with peaks in consumption of ungulate meat and mushrooms. Geophageous soils were distinguished from ungulate mineral licks and soils in general by exceptionally high concentrations of potassium (K) and high concentrations of magnesium (Mg) and sulphur (S). Our results do not support the hypotheses that bears were consuming soil to detoxify secondary compounds in grazed foliage, as postulated for primates, or to supplement dietary sodium, as known for ungulates. Our results suggest that grizzly bears could have been consuming soil as an anti-diarrheal.

    1999-11-01

    We introduce a young patient, without history of inflammatory bowel disease (I.B.D.) who started with an acute gastroenteritis, which in the following days progressed to a toxic megacolon. The patient had come to hospital with nausea, vomiting, fever and liquid, explosive diarrhoea without pathologic products. There was no clinical remission with astringent diet, hydroelectrolitic reposition and antidiarrheic opiates. The patient was admitted in hospital when he had blood in the diarrhoea. This progressed to a toxic megacolon in three days and the patient had to be operated on urgently. The surgeons found perforations in the colon and the pathologists diagnosed Crohn disease. Even without previous E.B.D. history we reached the diagnosis from the clinical and analytical data and the plain abdominal radiology. It was impossible to confirm the diagnosis with a colonoscopy because of the high risk of perforation. In cases like this, early surgery may save the life of the patient.

    2014-07-01

    Sweet basil, Ocimum basilicum, is one of the most important and wildly used spices and has been shown to have antioxidant, antibacterial, and anti-diarrheal activities. In this study, high performance liquid chromatographic (HPLC) and flow-injection mass spectrometric (FIMS) fingerprinting techniques were used to differentiate organic and conventional sweet basil leaf samples. Principal component analysis (PCA) of the fingerprints indicated that both HPLC and FIMS fingerprints could effectively detect the chemical differences in the organic and conventional sweet basil leaf samples. This study suggested that the organic basil sample contained greater concentrations of almost all the major compounds than its conventional counterpart on a per same botanical weight basis. The FIMS method was able to rapidly differentiate the organic and conventional sweet basil leaf samples (1min analysis time), whereas the HPLC fingerprints provided more information about the chemical composition of the basil samples with a longer analytical time.

  5. Diagnosis and Management of AIDS-related Diarrhea

    Directory of Open Access Journals (Sweden)

    John F Johanson

    1996-01-01

    Full Text Available The spectrum of illness associated with the acquired immunodeficiency syndrome (AIDS has been increasing since the initial description in 1981. While virtually all organ systems may be affected, the gastrointestinal tract appears to be a major target. Diarrhea is the most common symptom, affecting up to half of all AIDS patients during the course of their disease. Although diarrhea occurs frequently, its optimal management remains controversial. An extensive evaluation including stool studies and endoscopic biopsies of both the colon and small intestine has been widely recommended to identify all potential pathogenic organisms. An alternative approach is a more limited evaluation consisting of stool and blood cultures followed by symptomatic treatment with antidiarrheal agents if no specific organisms are identified. The clinical presentation of the most common opportunistic pathogens are reviewed, including several recently discovered organisms. Recommendations for treatment are followed by a brief discussion of management strategies used to care for patients with AIDS-related diarrhea.

    1988-01-01

    The actions of sennosides on colonic motility are incompletely understood. We therefore studied the effects of sennosides A + B on colonic myoelectric activity and transit of a radio-opaque meal in 7 conscious cats. Intraduodenal application of sennosides (2 mg/kg body weight) accelerated the half colon transit time from 60 +/- 10 (SEM) to 43 +/- 7 min. At the same time the ratio of long-spike bursts to short-spike bursts was changed from 0.22 to 10.1. Loperamide, an antidiarrheal agent, had the opposite effect. The overall spike activity was not altered by sennosides, but increased by loperamide. It is concluded that the propulsive action of sennosides in the colon is reflected by myoelectric patterns and not by the total number of spikes.

    Clarissa Fernanda de Queiroz Siqueira

    2012-01-01

    Full Text Available There are several species of plants used by traditional communities in the Brazilian semiarid. An approach used in the search for natural substances that possess therapeutic value is ethnobotany or ethnopharmacology. Active substances that have phenolic groups in their structure have great pharmacological potential. To establish a quantitative relationship between the species popularly considered to be antimicrobial, antidiabetic, and antidiarrheal, the contents of tannins and flavonoids were determined. The plant selection was based on an ethnobotanical survey conducted in a community located in the municipality of Altinho, northeastern Brazil. For determination of tannin content was utilized the technique of radial diffusion, and for flavonoids, an assay based on the complexation of aluminum chloride. The group of plants with antimicrobial indications showed a higher content of tannins compared to the control groups. The results evidence suggests a possible relationship between these compounds and the observed activity.

    While data are available on the effect of medicinal plants on intestinal motility and their antibacterial action, there is a paucity of information on their mode of action on various aspects of diarrheal pathogenicity, namely colonization to intestinal epithelial cells and production/action of enterotoxins. Crude decoction of dried leaves of Pongamia pinnata was evaluated for its antimicrobial (antibacterial, antigiardial and antirotaviral) effect; and its effect on production and action of enterotoxins (cholera toxin, CT; Escherichia coli labile toxin, LT; and E. coli stable toxin, ST); and adherence of enteropathogenic E. coli and invasion of enteroinvasive E. coli and Shigella flexneri to epithelial cells. The decoction had no antibacterial, antigiardial and antirotaviral activity, but reduced production of CT and bacterial invasion to epithelial cells. The observed results indicated that the crude decoction of P. pinnata has selective antidiarrheal action with efficacy against cholera and enteroinvasive bacterial strains causing bloody diarrheal episodes.

    Opium was known and frequently used in Roman society. Medical practice recognized its usefulness as an analgesic, soporific, anti-tussic or anti-diarrheic agent, as well as other currently unsupported uses with quasi-magical properties. It was additionally used as an ingredient in antidotes, panaceas and poisons. The authors present a non-exhaustive compilation of opium use according to medical doctors, writers and encyclopaedists of the time. Mythological and literary representations of the opium poppy reflected its diverse roles, being associated with prosperity and fertility, sleep, death and the underworld and with the art of medicine. Despite its free and routine use, there is no solid evidence of addiction, except the putative case of emperor Marcus Aurelius, consistently reported as one of the most likely cases of addiction to opium.

    Berberine, a benzylisoquinoline alkaloid, occurs as an active constituent in numerous medicinal plants and has an array of pharmacological properties. It has been used in Ayurvedic and Chinese medicine for its antimicrobial, antiprotozoal, antidiarrheal and antitrachoma activity. Moreover, several clinical and preclinical studies demonstrate ameliorative effect of berberine against several disorders including metabolic, neurological and cardiological problems. This review provides a summary regarding the pharmacokinetic and pharmacodynamic features of berberine, with a focus on the different mechanisms underlying its multispectrum activity. Studies regarding the safety profile, drug interactions and important clinical trials of berberine have also been included. Clinical trials with respect to neurological disorders need to be undertaken to exploit the beneficiary effects of berberine against serious disorders such as Alzheimer's and Parkinson's disease. Also, clinical studies to detect rare adverse effects of berberine need to be initiated to draw a complete safety profile of berberine and strengthen its applicability.

    Kratom (Mitragyna speciosa Korth.) is an indigenous plant of Thailand used traditionally in folk medicine although it is claimed to cause addiction. It is used to treat diarrhea, however, there is no scientific evidence to support the use. The aim of this study is to investigate the effect of methanolic extract of kratom leaves on the rat gastrointestinal tract. Kratom extract at 50, 100, 200 and 400 mg/kg (p.o.) caused a dose dependent protection against castor oil-induced diarrhea in rats and also inhibited intestinal transit. The antidiarrheal effect was not antagonized by naloxzone. The inhibition of intestinal transit by kratom extract was significantly different from the control when treated with a single dose for 1 day. For longer-term treatments of 15 and 30 days, kratom extract did not decrease the intestinal transit time indicating that adaptation had occurred. Kratom extract at a dose level of 200 and 400 mg/kg for 30 days and morphine at 3 mg/kg (i.p.) caused a decrease in the increment of body weight that was significantly different from the control and kratom extract at lower doses (50 and 100 mg/kg). However it had no effect on the level of plasma cholecystokinin. The results suggested that methanolic kratom extract exhibited its antidiarrheal effect on rat gastrointestinal tract. The effects may occur via pathways in addition to the action on opioid receptors. High does of kratom extract decreased the increment of body weight similar to the effect of morphine.

    AIM: Racecadotril is a specific enkephalinase inhibitor that exhibits intestinal antisecretory activity without affecting intestinal transit. Loperamide is an effective anti-diarrheal agent, but it usually induces constipation. This study is to compare the efficacy, safety, and tolerability of racecadotril versus Ioperamide in the outpatient treatment of acute diarrhea in adults.METHODS: A two-center, randomized, parallel-group,single-blind study was carried out to compare the efficacy,tolerability, and safety of racecadotril (100 mg thrics daily)and Ioperamide (2.0 mg 2 twics daily) in 62 adult patients suffering from acute diarrhea. The main efficacy criterion used was the duration of diarrhea after beginning the treatment (in hours). Other signs and symptoms were also evaluated.RESULTS: The clinical success rates for these antidiarrheal treatments were 95.7% and 92.0% for racecadotril and Ioperamide respectively. Patients on racecadotril had a median duration of diarrhea of 19.5 h compared with a median of 13 h for patients on Ioperamide.Rapid improvement in anal burn and nausea was found for each drug. However, more patients on Ioperamide suffered from reactive constipation (29.0% vs 12.9%).Itching, another adverse event was notably higher in the racecadotril group (28.6% vs 0%). With regard to other adverse events, the two medications showed similar occurrence rates and similar concomitant medication usage rates.CONCLUSION: Racecadotril and Ioperamide are rapid,equally effective treatments for acute diarrhea in adults,but Ioperamide treatment is associated with a higher incidence of treatment-related constipation.

    ; 5 - pathology immunosuppression + reference drug. Results and discussion. Laktovit Forte (BC showed pronounced Antidiarrheal effect - the effect was 75%, and in immunodeficiency conditions only 50%. The antidiarrheal effect of the drug based on comparison lactobacilli was 60% in both groups. Similar trends were observed in level of intestinal motility. The Laktovit Forte decreased high intestinal motility during pathology at 61%; in immunosuppression conditions - only 54%. Comparing the drug produced a less pronounced effect, but similar in the groups with and without immunosuppression - respectively 44.5 and 45.9%. BC effects differently under immunosuppressant conditions and without; indicating the importance of immune component in the mechanism of its action in antibiotic-associated diarrhea. The drugs based on comparison bacteria have less pronounced effect, indicating that its probiotic effects and the absence of immune system direct stimulation. The Laktovit Forte is also more effective in preventing body weight loss in animal than comparison drug on the background of the development pathology. For all studies indicates Laktovit Forte was significantly more effective than the drug on the other lactobacillus. Conclusion. Bacillus coagulans from Laktovit Forte provided antidiarrheal effect not only due to the antagonistic probiotic action, but also due to direct stimulation of the immune system.

    Full Text Available A diarréia constitui uma das principais causas de morbi-mortalidade na infância. As farmácias são locais bastante procurados pela população para resolução de problemas de saúde. Visando contribuir para o uso racional de medicamentos, mediante promoção da TRO, foi realizado um estudo de intervenção em farmácias de Corumbá e Ladário. Os medicamentos mais indicados foram SRO (50%, antidiarréicos (39%, Sulfametoxazol/Trimetoprim (27% e levedo (22% na entrevista semi-estruturada; SRO (75%, Sulfametoxazol/Trimetoprim (25% e levedo (25% nas respostas ao questionário, demonstrando a importância do uso de mais de uma metodologia para a obtenção de dados fidedignos. A intervenção educativa foi realizada em 86,7% das farmácias. Os resultados mostraram que mesmo tendo adquirido conhecimento do manejo adequado da diarréia, os trabalhadores de farmácia ainda recomendam outros medicamentos e não SRO exclusivamente. O trabalho evidencia que para conseguir a adesão dos trabalhadores de farmácia aos protocolos oficiais para episódios diarréicos, necessita-se também de medidas normativas em relação aos medicamentos contra-indicados para crianças e reformular as atividades da farmácia e do farmacêutico.Diarrhea is a major cause of morbidity and mortality in childhood, and Brazilians rely heavily on pharmacies for the resolution of this and other health problems.

    2015-12-01

    Loperamide, a common over-the-counter antidiarrheal drug and opioid derivative, is formulated to act upon intestinal opioid receptors. However, at high doses, loperamide crosses the blood-brain barrier and reaches central opioid receptors in the brain, leading to central opiate effects including euphoria and respiratory depression. We report the case of a young man found dead in his residence with a known history of drug abuse. At autopsy, the only significant findings were a distended bladder and bloody oral purge. Drug screening found nontoxic levels of alprazolam, fluoxetine, and marijuana metabolites. Liquid chromatography time-of-flight mass spectrometry found an unusual set of split isotope peaks consistent with chlorine. On the basis of autopsy and toxicological findings, loperamide toxicity was suspected because of its opioid properties and molecular formula containing chlorine. A sample of loperamide was analyzed by liquid chromatography time-of-flight mass spectrometry, resulting in a matching mass and retention time to the decedent's sample. Subsequently, quantitative testing detected 63 ng/mL of loperamide or more than 6 times of therapeutic peak concentration. Cause of death was determined as "toxic effects of loperamide with fluoxetine and alprazolam." Because of its opioid effects and easy accessibility, loperamide is known as "poor man's methadone" and may go undetected at medical and forensic drug screening.

    Full Text Available Cocos nucifera (L. (Arecaceae is commonly called the “coconut tree” and is the most naturally widespread fruit plant on Earth. Throughout history, humans have used medicinal plants therapeutically, and minerals, plants, and animals have traditionally been the main sources of drugs. The constituents of C. nucifera have some biological effects, such as antihelminthic, anti-inflammatory, antinociceptive, antioxidant, antifungal, antimicrobial, and antitumor activities. Our objective in the present study was to review the phytochemical profile, pharmacological activities, and toxicology of C. nucifera to guide future preclinical and clinical studies using this plant. This systematic review consisted of searches performed using scientific databases such as Scopus, Science Direct, PubMed, SciVerse, and Scientific Electronic Library Online. Some uses of the plant were partially confirmed by previous studies demonstrating analgesic, antiarthritic, antibacterial, antipyretic, antihelminthic, antidiarrheal, and hypoglycemic activities. In addition, other properties such as antihypertensive, anti-inflammatory, antimicrobial, antioxidant, cardioprotective, antiseizure, cytotoxicity, hepatoprotective, vasodilation, nephroprotective, and anti-osteoporosis effects were also reported. Because each part of C. nucifera has different constituents, the pharmacological effects of the plant vary according to the part of the plant evaluated.

    Full Text Available The aim of the present work was to study the functional nature of the potential spasmolytic effect of the crude extract of Sauromatum guttaum. It was found positive for the presence of alkaloid and tannins. In isolated rabbit jejunum preparation, S. guttaum caused inhibition of spontaneous and high K+ (80 mM-induced contractions, with respective EC50 values (95% confidence intervals of 1.50 mg/mL (0.69-3.02 and 1.17 mg/mL (0.81-1.61, similar to verapamil. Inhibition of high K+ -induced contractions suggests Ca++ antagonistic effect. The Ca++channel blocker activity of S. guttaum was confirmed when pre-treatment of the tissues with extract (0.3-3 mg/mL caused a rightward displacement in the Ca++ concentration-response curves. Moreover, in the acute toxicity test, S. guttaum was found safe up to the dose of 3 g/kg. The findings of the current study suggest that the S. guttaum exhibited spasmolytic activity, possibly mediated through inhibitory effect on Ca++ entry and was found safe and this current study provides first evidence to the potential use of this plant as antispasmodic and can play a possible role as antidiarrheal.

    Popularly known as “açoita-cavalo” (whips-horse), Luehea species (Malvaceae-Tilioideae) are native to America and are used in folk medicine as anti-inflammatory, antidiarrheal, antiseptic, expectorant, and depurative and against skin infections. Although there are studies showing the chemical constituents of some species, the active substances have not been properly identified. A systematic study was carried out through a computer search of data on CAPES journals, SciELO, ISI Bireme, PubMed, ScienceDirect, ScienceDomain Medline, and Google Scholar from published articles using key words: Luehea, açoita-cavalo, and Malvaceae. Luehea divaricata was the species with the highest number of studies observed. Triterpenes (9), flavonoids (6), and steroids (4), including saponins, organic acids (4), and one lignan, are the main types of secondary metabolites registered and the most cited flavonoids were rutin and quercetin and among triterpenes there was maslinic acid, which might be associated with the popular indication of its anti-inflammatory action. The vitexin, a C-glycosylated flavone, isolated from three different species, is cited as a possible taxonomic marker of the genus. Studies confirm in part the medicinal uses of plants named as “açoita-cavalo” species. Some pharmacological activities, not assigned to the species of the genus Luehea by populations, were observed in laboratory experiments. PMID:27818835

    Octreotide is an effective therapeutic option in controlling secretory diarrhea of varied etiology. However, marked patient-to-patient differences in the antidiarrheal effects necessitate titration of octreotide dose in individual patients to achieve optimal symptom control. A consensus development panel established guidelines for octreotide dose titration in patients with secretory diarrhea. Overall, the panel recommended an aggressive approach in selecting the initial octreotide dose and in making subsequent dose escalations in patients with secretory diarrhea due to gastrointestinal tumors (eg, carcinoids, VIPomas), AIDS, dumping syndrome, short bowel syndrome, radiotherapy, or chemotherapy. To avoid hypoglycemia in patients with diabetes mellitus-associated secretory diarrhea, the panel recommended a low initial octreotide dose and a conservative titration regimen with close monitoring a blood glucose levels. The end point of therapy should focus on a reduction in diarrhea (frequency of bowel movements or stool volume) rather than normalization of hormonal profile. Overall, octreotide is well tolerated; principal side effects are transient injection site pain and gastrointestinal discomfort. For many patients with secretory diarrhea, octreotide therapy is expected to improve the overall health and quality of life and in the long run will lessen health care costs.

    Campomanesia adamantium (Myrtaceae) is popularly known as “gabiroba” and has been used in folk medicine as antirheumatic, antidiarrheal, hypocholesterolemic and anti-inflammatory. This study evaluated the anti-inflammatory and antinociceptive activities and toxicology of essential oils from peel (EOP) and seed (EOS) of C. adamantium fruits in animal models. Different groups were treated with doses of 100 and 300 mg/kg and the inflammatory parameters were evaluated in carrageenan induced paw oedema and leukocyte migration in pleurisy model, while antinociceptive activity was evaluated using formalin method in rodents. The major constituent of EOP and EOS was limonene with 13.07% and 20.89%, respectively. No clinical signs of toxicity have been observed in animals. It was observed a significant decreased (Pnociception test. In the first formalin-phase, maximal inhibitions were at 48±5% for EOP and 66±4% for EOS (300 mg/kg). At the inflammatory phase induced by formalin, maximal inhibitions were 72±2% for EOP and 80±2% for EOS at the dose of 100 mg/kg. Seed and peel essential oils from C. adamantium fruit inhibited leukocyte migration, inflammatory and neurogenic pain and oedema suggesting their use as nutraceutical or pharmacological agent.

    Polygonatum verticillatum (Linn.) All. syn.Convallaria verticillata Linn. is a valuable medicinal plant, distributed in the temperate Himalaya at the elevations 2 400 to 2 800 m. It is a perennial rhizomatous herb and contains various pharmacologically important secondary metabolites among which the most important areα-bulnesene, linalyl acetate, eicosadienoic, pentacosane, piperitone, docasane, diosgenin, santonin and calarene. It also possesses antimalarial, antipyretic, anti-inflammatory, anticonvulsant, lipoxygenase, urease inhibition, diuretic, tracheorelaxant, antidiarrheal, antispasmodic, antinociceptive, antifungal, antibacterial and bronchodilator activities. The plant also got importance in traditional systems of medicine due to its broad therapeutic potential especially of its rhizome. But in the past few years, over exploitation of plant parts caused the decline in the frequency of this species due to which it became threatened, endangered and vulnerable in different parts of the world. So efforts are being made in certain regions of the world for bothex-situ and in-situ conservation. This paper briefly reviewed the botanical, traditional, phytochemical, pharmacological and conservation related aspects of this plant.

    Full Text Available Diarrheal diseases are the second highest cause of mortality of children under 5 years worldwide. There is a continuous search for developing a cost-effective treatment for diarrhea as the present ones are facing challenges. Medicinal plants can be explored further as an alternative treatment for diarrhea. Psidium guajava leaves have been used as an antidiarrheal globally. Citrobacter rodentium, a common mouse pathogen, is known to mimic the pathogenecity of enteropathogenic and enterohemorrhagic E. coli. It can thus present an effective model to study infectious diarrhea. In the present study, the P. guajava leaf extract was tested for its efficacy in treating infectious diarrhea using a C. rodentium mouse model. The mice in the test group (treated with P. guajava leaf extract showed quicker clearance of infection as compared with the control group. The bacterial load in the fecal sample of the mice in the test group was high on Day 4 as compared with that in the control group, suggesting a flush out of the bacteria. In the test group, 6/7 (85.71% mice showed clearance of infection by Day 19. The control group continued to show infection till Day 29. P. guajava leaf extract thus has the potential for use in the treatment of infectious diarrhea.

    Full Text Available Secretory diarrhea remains a global health burden and causes major mortality in children. There have been some focuses on antidiarrheal therapies that may reduce fluid losses and intestinal motility in diarrheal diseases. In the present study, we identified shikonin as an inhibitor of TMEM16A chloride channel activity using cell-based fluorescent-quenching assay. The IC50 value of shikonin was 6.5 μM. Short-circuit current measurements demonstrated that shikonin inhibited Eact-induced Cl current in a dose-dependent manner, with IC50 value of 1.5 μM. Short-circuit current measurement showed that shikonin exhibited inhibitory effect against CCh-induced Cl currents in mouse colonic epithelia but did not affect cytoplasmic Ca2+ concentration as well as the other major enterocyte chloride channel CFTR. Characterization study found that shikonin inhibited basolateral K+ channel activity without affecting Na+/K+-ATPase activities. In-vivo studies revealed that shikonin significantly delayed intestinal motility in mice and reduced stool water content in a neonatal mice model of rotaviral diarrhea without affecting the viral infection process in-vivo. Taken together, the results suggested that shikonin inhibited enterocyte CaCCs, the inhibitory effect was partially through inhbition of basolateral K+ channel acitivty, and shikonin could be a lead compound in the treatment of rotaviral secretory diarrhea.

    The prognosis of acute diarrhoea in infants is most often satisfactory in industrialized countries. However, it has been estimated that 10 to 15 children die every year in France from acute dehydration due to acute diarrhoea. In spite of an increasing use over the least few years, oral rehydration solutions (ORS) are used in only 70% of infants presenting with acute diarrhoea. The use of homemade ORS, plain water or fizzy drink should be strictly avoided. In case of acute diarrhoea there is no indication to stop breastfeeding or the use of infant formula for more than 4 hours. Lactose intolerance is observed in only 5-10% of infants. Lactose free formulae should only be used in infants with severe, persistent or recurrent diarrhoea. Under 3-4 months of age, infants with severe diarrhoea should receive for a period of 2-4 weeks lactose free protein hydrolysate formulae. Racecadotril is the only drug with anti-diarrheal properties, with a reduction of the stool output of 50%. Oral antibiotics should only be used in case of Shigella infection or in case of bacterial infection with severe sepsis or underlying debilitating disease. Oral Rotavirus vaccine, that is not reimbursed yet in France, has been shown to dramatically reduce the number of severe cases of diarrhoea with dehydration, and has been associated with a striking reduction of both morbidity and mortality, as well as of the number of hospitalisations during periods of epidemics.

    Full Text Available The root of Rubia cordifolia (R. cordifolia has been used traditionally as a hemostatic agent, while the aerial part of the plant consisting of leaf and stem is known to exhibit anti-diarrheal properties and has been widely used as a remedy in many parts of China. As rotavirus is one of the most commonly associated diarrhea-causing pathogen, this study aims to investigate the anti-rotaviral effect of R. cordifolia aerial part (RCAP. The cytotoxicity of RCAP towards MA-104 cells was evaluated using the WST-8 assay. Colloidal gold method and real time polymerase chain reaction (qPCR assay were used to confirm the findings of the antiviral assay. Then, 4',6-diamidino-2-phenylindole (DAPI staining method was subsequently used to investigate the mode of death among the cells. And the representative components of aqueous extract were isolated and identified. It was shown that both the viability of MA-104 cells and the viral load were reduced with increasing concentration of the extract. DAPI staining showed that virus-induced apoptosis was the cause of the low cell viability and viral load, an effect which was accelerated with incubation in the aqueous herbal extract. The major compounds postulated to exhibit this activity were isolated from the aqueous herbal extract and identified to be compounds Xanthopurpurin and Vanillic Acid. This study showed that RCAP extract effectively inhibited rotavirus multiplication by promoting virus-induced apoptosis in MA-104 cells.

    Full Text Available Microscopic colitis (MC encompasses the two morphologically distinct entities of collagenous colitis (CC and lymphocytic colitis (LC. MC was first described less than 30 years ago but is presently recognized as a relatively common cause of chronic diarrhea in the adult population. Remarkably, up to 10% of adults who have a colonoscopy for the investigation of chronic diarrhea, and have endoscopically normal appearing mucosa, may have MC. Patients with MC generally present with chronic diarrhea, which can be associated with cramping and bloating. Endoscopic and radiological examinations are usually normal. Histological assessment reveals inflammation consisting predominantly of lymphocytic infiltration, and a thickened subepithelial collagen band is diagnostic of CC. Both LC and CC can be associated with autoimmune diseases such as celiac disease, diabetes, arthritis and thyroiditis, yet the mechanisms involved in the pathogenesis remain unclear. Emerging studies suggest that a stepwise approach be taken in the medical management of MC. This approach includes antidiarrheal agents and stopping of any offending agents; budesonide or bismuth subsalicylate; and cholestyramine or 5-acetylsalicylic acid agents. In resistant cases, oral corticosteroids and other immune modulatory therapy have been used.

    The 2014 outbreak clearly showed that Ebola viruses (EBOV) remain a substantial threat for public health. The mainstay of management of patients with Ebola disease is isolation of patients and use of strict barrier nursing procedures; the present treatment strategies are mainly symptomatic and supportive (fluid resuscitation, antypyretics, antidiarrheal drugs). Currently, there is no approved therapy for Ebola hemorrhagic fever (EHF), however several advanced treatment options were tested in animal models (on non-human primates or rodents). They include use of both symptomatic (e.g. use of tissue factor inhibitors - rhNAPc2, rhAPC - to abolish coagulopathy) and specific antiviral approaches: e.g. monoclonal anti EBOV antibodies (ZMapp, MB-003), phosphorodiamidate morpholino oligomers (PMOs), liposomes containing siRNA (LNP-siRNA:TKM-Ebola) and small molecule inhibitors (e.g. BCX4430, favipiravir). The scope of this article is to briefly review the most promising therapeutics for EHF, based on the data coming from rare clinical reports, studies on animals and results from in vitro models.

    Hydroxylases are oxygen-sensing enzymes that regulate cellular responses to hypoxia. Transepithelial Cl(-) secretion, the driving force for fluid secretion, is dependent on O(2) availability for generation of cellular energy. Here, we investigated the role of hydroxylases in regulating epithelial secretion and the potential for targeting these enzymes in treatment of diarrheal disorders. Ion transport was measured as short-circuit current changes across voltage-clamped monolayers of T(84) cells and mouse colon. The antidiarrheal efficacy of dimethyloxallyl glycine (DMOG) was tested in a mouse model of allergic disease. Hydroxylase inhibition with DMOG attenuated Ca(2+)- and cAMP-dependent secretory responses in voltage-clamped T(84) cells to 20.2 +\\/- 2.6 and 38.8 +\\/- 6.7% (n=16; P<\\/=0.001) of those in control cells, respectively. Antisecretory actions of DMOG were time and concentration dependent, being maximal after 18 h of DMOG (1 mM) treatment. DMOG specifically inhibited Na(+)\\/K(+)-ATPase pump activity without altering its expression or membrane localization. In mice, DMOG inhibited agonist-induced secretory responses ex vivo and prevented allergic diarrhea in vivo. In conclusion, hydroxylases are important regulators of epithelial Cl(-) and fluid secretion and present a promising target for development of new drugs to treat transport disorders.

    Myrtaceae family (121 genera, 3800-5800 spp.) is one of the most important families in tropical forests. They are aromatic trees or shrubs, which frequently produce edible fruits. In the neotropics, ca. 1000 species were found. Several members of this family are used in folk medicine, mainly as an antidiarrheal, antimicrobial, antioxidant, cleanser, antirheumatic, and anti-inflammatory agent and to decrease the blood cholesterol. In addition, some fruits are eaten fresh or used to make juices, liqueurs, and sweets very much appreciated by people. The flavor composition of some fruits belonging to the Myrtaceae family has been extensively studied due to their pleasant and intense aromas. Most of the essential oils of neotropical Myrtaceae analyzed so far are characterized by predominance of sesquiterpenes, some with important biological properties. In the present work, chemical and pharmacological studies carried out on neotropical Myrtaceae species are reviewed, based on original articles published since 1980. The uses in folk medicine and chemotaxonomic importance of secondary metabolites are also briefly discussed.

    Full Text Available The plant species Arbutus unedo shows numerous beneficial pharmacological effects (antiseptic, antidiabetic, antidiarrheal, astringent, depurative, antioxidant, antihypertensive, antithrombotic, and anti-inflammatory. For the medicinal use, standardization of extracts is a necessity, as different compounds are responsible for different biological activities. In this paper, we analyze monthly changes in the content of quercitrin, isoquercitrin, hyperoside, and chlorogenic acid. Methanolic extracts of the leaves are analyzed by HPTLC for the identification and quantification of individual polyphenol, and DPPH test is used to determine antioxidant activity. Based on the results obtained, the leaves should be collected in January to obtain the highest concentrations of hyperoside and quercitrin (0.35 mg/g and 1.94 mg/g, resp., in June, July, and October for chlorogenic acid (1.45–1.46 mg/g, and for the fraction of quercitrin and isoquercitrin in November (1.98 mg/g and 0.33 mg/g, resp.. Optimal months for the collection of leaves with the maximum recovery of individual polyphenol suggested in this work could direct the pharmacological usage of the polyvalent herbal drugs.

    Full Text Available Jatropha gossypiifolia L. (Euphorbiaceae, widely known as “bellyache bush,” is a medicinal plant largely used throughout Africa and America. Several human and veterinary uses in traditional medicine are described for different parts and preparations based on this plant. However, critical reviews discussing emphatically its medicinal value are missing. This review aims to provide an up-to-date overview of the traditional uses, as well as the phytochemistry, pharmacology, and toxicity data of J. gossypiifolia species, in view of discussing its medicinal value and potential application in complementary and alternative medicine. Pharmacological studies have demonstrated significant action of different extracts and/or isolated compounds as antimicrobial, anti-inflammatory, antidiarrheal, antihypertensive, and anticancer agents, among others, supporting some of its popular uses. No clinical trial has been detected to date. Further studies are necessary to assay important folk uses, as well as to find new bioactive molecules with pharmacological relevance based on the popular claims. Toxicological studies associated with phytochemical analysis are important to understand the eventual toxic effects that could reduce its medicinal value. The present review provides insights for future research aiming for both ethnopharmacological validation of its popular use and its exploration as a new source of herbal drugs and/or bioactive natural products.

    E. oleracea is a tropical plant from the Amazon region, with its fruit used for food, and traditionally, as an antioxidant, anti-inflammatory, hypocholesterolemic, for atherosclerotic disease, and has anticancer properties. The oil of the fruit has antidiarrheic, anti-inflammatory and antinociceptive activities, but without genotoxicity evaluation. Therefore, the aim of this study was to evaluate the genotoxic potential of E. oleracea fruit oil (EOO), in rat cells. Male Wistar rats were treated with EOO by gavage at doses of 30, 100 and 300 mg/kg, for 14 days, within a 24 h interval. The DNA damage in the leukocytes, liver, bone marrow and testicular cells, was assessed by the comet assay, and the clastogenic/aneugenic effects in the bone marrow cells, by the micronucleus test. Our phytochemicals characterization of the EOO showed the presence of vanillic, palmitic, γ-linolenic, linoleic, oleic, cinnamic, caffeic, protocatechuic, ferulic, syringic acids, and flavonoids quercetin and kaempferol rutinoside as the main constituents. Both cytogenetic tests performed showed that EOO presented no significant genotoxic effects in the analyzed cells, at the three tested doses. These results indicate that, under our experimental conditions, E. oleracea fruit oil did not reveal genetic toxicity in rat cells.

    The insect diet of chimpanzees and gorillas living at the northern periphery of the Dja Biosphere Reserve in southeast Cameroon and its nutritional contribution is described. We analyzed fecal samples and recorded additional evidence of insectivory. A detailed prey species list is presented for both apes. We carried out nutritional analyses (macronutrients, macro- and micro-minerals) on 11 important and eight nonimportant, but accessible, ant and termite prey species, and estimated the average nutrient intake/day through insects. Although gorillas ate insects more frequently, the average prey biomass intake/day by chimpanzees was twice that by gorillas. The lack of tool-use by gorillas cannot be the main reason for the small overlap of important prey species. Both apes did not seem to consume ant prey for one or more specific nutrients. Also other factors, such as medicinal use, should be considered. Termites, on the other hand, seemed to be selected for particular nutrients. Gorilla intake of the important termite prey, Cubitermes and Thoracotermes, met with estimated iron requirements. Their potential role as antidiarrheal treatment is as yet unclear. Chimpanzee intake of the important termite prey, Macrotermes spp., met with estimated manganese requirements and the protein intake/day (mean: 2 g/d) reached significant values (>20 g/d). To fully understand the importance of nutritional contributions of insects to ape diets in Cameroon, the chemical composition and nutrient intake of fruit and foliage in their diets should be investigated.

    Opium is one of the oldest herbal medicines currently used as an analgesic, sedative and antidiarrheal treatment. The effects of opium are principally mediated by the μ-, κ- and δ-opioid receptors. Opioid substances consist of all natural and synthetic alkaloids that are derived from opium. Most of their effects on gastrointestinal motility and secretion result from suppression of neural activity. Inhibition of gastric emptying, increase in sphincter tone, changes in motor patterns, and blockage of peristalsis result from opioid use. Common adverse effects of opioid administration include sedation, dizziness, nausea, vomiting, constipation, dependency and tolerance, and respiratory depression. The most common adverse effect of opioid use is constipation. Although stool softeners are frequently used to decrease opioid-induced bowel dysfunction, however they are not efficacious. Possibly, the use of specific opioid receptor antagonists is a more suitable approach. Opioid antagonists, both central and peripheral, could affect gastrointestinal function and visceromotor sensitivity, which suggests an important role for endogenous opioid peptides in the control of gastrointestinal physiology. Underlying diseases or medications known to influence the central nervous system (CNS) often accelerate the opioid’s adverse effects. However, changing the opioid and/or route of administration could also decrease their adverse effects. Appropriate patient selection, patient education and discussion regarding potential adverse effects may assist physicians in maximizing the effectiveness of opioids, while reducing the number and severity of adverse effects.

    Binding of cholera toxin to ganglioside receptors of enterocyte microvilli catalyzes the activation of adenylate cyclase causing a rise in cAMP which final result is a copious diarrhea. Saccharomyces boulardii, a nonpathogenic yeast has been used to prevent diarrhea. Although the antidiarrheic properties of S. boulardii are widely recognized, this yeast has been used on empirical basis, and the mechanism of this protective effect is unknown. The addition of cholera toxin to S. boulardii induces the raising of cAMP that triggers the activation of neutral trehalase. This suggests that toxin specifically binding to cells, is internalized and active the protein phosphorylation cascade. Our objective is labeling the cholera toxin to verify the presence of binding sites on yeast cell surfaces for the cholera toxin. Cholera toxin was radiolabelled with Na {sup 125} I by a chloramine-T method modified from Cuatrecasas and Griffiths et alii. The {sup 125} I-Cholera toxin showed a specific radioactivity at about 1000 cpm/fmol toxin. Biological activity of labeled cholera toxin measured by trehalase activation was similar to the native toxin. (author) 5 refs., 3 figs.; e-mail: nevesmj at urano.cdtn.br

    Stevia rebaudiana Bertoni is a small perennial shrub of the Asteraceae (Compositae) family that is native to South America, particularly Brazil and Paraguay, where it is known as "stevia" or "honey leaf" for its powerful sweetness. Several studies have suggested that in addition to their sweetness, steviosides and their related compounds, including rebaudioside A and isosteviol, may offer additional therapeutic benefits. These benefits include anti-hyperglycaemic, anti-hypertensive, anti-inflammatory, anti-tumor, anti-diarrheal, diuretic, and immunomodulatory actions. Additionally, critical analysis of the literature supports the anti-bacterial role of steviosides on oral bacteria flora. The aim of this review is to show the emerging results regarding the anti-cariogenic properties of S. rebaudiana Bertoni. Data shown in the present paper provide evidence that stevioside extracts from S. rebaudiana are not cariogenic. Future research should be focused on in vivo studies to evaluate the effects on dental caries of regular consumption of S. rebaudiana extract-based products.

    Short bowel syndrome (SBS) refers to the clinical consequences resulting from loss of small bowel absorptive surface area due to surgical resection or bypass. The syndrome is characterized by maldigestion, malabsorption, and malnutrition. Survival of patients with SBS is dependent on adaptation in the remaining bowel and a combination of pharmacologic and nutrition therapies. Individual plans of care are developed based on the length and sites of remaining bowel, the degree of intestinal adaptation, and the patient's ability to adhere to the medication and dietary regimens. Antisecretory and antidiarrheal medications are prescribed to slow intestinal transit times and optimize fluid and nutrient absorption. Based on postsurgical anatomy, enteral feedings, parenteral infusions, complex diet plans, and vitamin and mineral supplementation are used in various combinations to nourish patients with SBS. In the acute care setting, registered dietitians (RDs) assist with infusion therapy, diet education, and discharge planning. Long-term, as the small intestine adapts, RDs revise the nutrition care plan and monitor for nutrient deficiencies, metabolic bone disease, and anemia. The frequent monitoring and revision of care plans, plus the appreciable benefits from proper medical nutrition therapy, make this patient population extremely challenging and rewarding for RDs to manage. This article provides a brief, case study-based overview of the medical and nutrition management of SBS.

    Short bowel syndrome-associated intestinal failure (SBS-IF) as a consequence of extensive surgical resection of the gastrointestinal (GI) tract results in a chronic reduction in intestinal absorption. The ensuing malabsorption of a conventional diet with associated diarrhea and weight loss results in a dependency on parenteral nutrition and/or intravenous fluids (PN/IV). A natural compensatory process of intestinal adaptation occurs in the years after bowel resection as the body responds to a lack of sufficient functional nutrient-processing intestinal surface area. The adaptive process improves bowel function but is a highly variable process, yielding different levels of symptom control and PN/IV independence among patients. Intestinal rehabilitation is the strategy of maximizing the absorptive capacity of the remnant GI tract. The approaches for achieving this goal have been limited to dietary intervention, antidiarrheal and antisecretory medications, and surgical bowel reconstruction. A targeted pharmacotherapy has now been developed that improves intestinal absorption. Teduglutide is a human recombinant analogue of glucagon-like peptide 2 that promotes the expansion of the intestinal surface area and increases the intestinal absorptive capacity. Enhanced absorption has been shown in clinical trials by a reduction in PN/IV requirements in patients with SBS-IF. This article details the clinical considerations and best-practice recommendations for intestinal rehabilitation, including optimization of fluids, electrolytes, and nutrients; the integration of teduglutide therapy; and approaches to PN/IV weaning.

    Melanoma is a highly malignant neoplasm of melanocytes with considerable metastatic potential and drug resistance, explaining the need for new candidates that inhibit tumor growth and metastasis. The signal transducer and activator of the transcription 3 (Stat3) signaling pathway plays an important role in melanoma and has been validated as promising anticancer target for melanoma therapy. In this study, nifuroxazide, an antidiarrheal agent identified as an inhibitor of Stat3, was evaluated for its anti-melanoma activity in vitro and in vivo. It had potent anti-proliferative activity against various melanoma cell lines and could induce G2/M phase arrest and cell apoptosis. Moreover, nifuroxazide markedly impaired melanoma cell migration and invasion by down-regulating phosphorylated-Src, phosphorylated-FAK, and expression of matrix metalloproteinase (MMP) -2, MMP-9 and vimentin. It also significantly inhibited tumor growth without obvious side effects in the A375-bearing mice model by inducing apoptosis and reducing cell proliferation and metastasis. Notably, nifuroxazide significantly inhibited pulmonary metastases, which might be associated with the decrease of myeloid-derived suppressor cells (MDSCs). These findings suggested that nifuroxazide might be a potential agent for inhibiting the growth and metastasis of melanoma.

    Breast carcinoma is the most common female cancer with considerable metastatic potential. Signal transducers and activators of the transcription 3 (Stat3) signaling pathway is constitutively activated in many cancers including breast cancer and has been validated as a novel potential anticancer target. Here, we reported our finding with nifuroxazide, an antidiarrheal agent identified as a potent inhibitor of Stat3. The potency of nifuroxazide on breast cancer was assessed in vitro and in vivo. In this investigation, we found that nifuroxazide decreased the viability of three breast cancer cell lines and induced apoptosis of cancer cells in a dose-dependent manner. In addition, western blot analysis demonstrated that the occurrence of its apoptosis was associated with activation of cleaved caspases-3 and Bax, downregulation of Bcl-2. Moreover, nifuroxazide markedly blocked cancer cell migration and invasion, and the reduction of phosphorylated-Stat3(Tyr705), matrix metalloproteinase (MMP) MMP-2 and MMP-9 expression were also observed. Furthermore, in our animal experiments, intraperitoneal administration of 50 mg/kg/day nifuroxazide suppressed 4T1 tumor growth and blocked formation of pulmonary metastases without detectable toxicity. Meanwhile, histological and immunohistochemical analyses revealed a decrease in Ki-67-positive cells, MMP-9-positive cells and an increase in cleaved caspase-3-positive cells upon nifuroxazide. Notably, nifuroxazide reduced the number of myeloid-derived suppressor cell in the lung. Our data indicated that nifuroxazide may potentially be a therapeutic agent for growth and metastasis of breast cancer.

    Full Text Available The acute toxicity, the antioxidant activity, and the pharmacological activity on the gastrointestinal tract of rodents of the ethanolic extract (TFEE from the bark of Terminalia fagifolia Mart. & Zucc. (Combretaceae and of its aqueous (TFAqF, hydroalcoholic (TFHAF, and hexanic (TFHEXF partition fractions have been evaluated. TFEE presented low acute toxicity, antioxidant, and antiulcerogenic activity against ethanol-induced ulcers, which was partially blocked by pretreatment with L-NAME and indomethacin. It reduced the total acidity and raised the pH of gastric secretion. Additionally, TFEE delayed gastric emptying and slightly inhibited the small intestinal transit and also presented a weakly antidiarrheal activity. The antiulcerogenic and antioxidant activity were also detected in TFAqF and TFHAF but not in TFHEXF. The antisecretory and gastroprotective activity of TFEE partially involve the nitric oxide and prostaglandin participation. Nevertheless, TFEE, TFAqF, and TFHAF drastically reduced the mucus layer adhered to the gastric wall of rats treated with ethanol or indomethacin. Complementary studies are required in order to clarify the paradox of the presence of a gastroprotector activity in this plant that, at the same time, reduces the mucus layer adhered to the gastric wall.

    Full Text Available Evidence from epidemiological studies suggests that plant-based diets can reduce the risk of prostate cancer. However, very little information is available concerning the use of botanicals in preventing prostate cancer. As a first step toward developing botanicals as prostate cancer preventives, we examined the effect of Nexrutine on human prostate cancer cells. Nexrutine is a herbal extract developed from Phellodendron amurense. Phellodendron extracts have been used traditionally in Chinese medicine for hundreds of years as an antidiarrheal, astringent, and anti-inflammatory agent. The present study investigated its potential antitumor effect on human prostate cancer cells. Our results suggest that it inhibits tumor cell proliferation through apoptosis induction and inhibition of cell survival signaling. The results of the present study indicate that Nexrutine treatment 1 inhibits the proliferation of both androgenresponsive and androgen-independent human prostate cancer cells through induction of apoptosis; 2 reduces levels of pAkt, phosphorylated cAMP response-binding protein (pCREB, and CREB DNA-binding activity; and 3 induces apoptosis in prostate cancer cells stably overexpressing Bcl-2. Further Akt kinase activity was reduced in cells treated with Nexrutine, and ectopic expression of myristoylated Akt protected from Nexrutine induced inhibition of proliferation, implicating a role for Akt signaling.

    Vibrio cholerae is one of the major bacterial pathogens responsible for the devastating diarrheal disease called cholera. Chemotherapy is often used against V. cholerae infections; however, the emergence of V. cholerae with multidrug resistance (MDR) toward the chemotherapeutic agents is a serious clinical problem. This scenario has provided us with the impetus to look into herbal remediation, especially toward blocking the action of cholera toxin (CT). Our studies were undertaken to determine the antidiarrheal potential of 6-gingerol (6G) on the basis of its effect on CT, the virulence factor secreted by V. cholerae. We report here that 6G binds to CT, hindering its interaction with the GM1 receptor present on the intestinal epithelial cells. The 50% inhibitory concentration (IC50) was determined to be 10 μg/ml. The detailed mechanistic study was conducted by enzyme-linked immunosorbent assay (ELISA), fluorescence spectroscopy, and isoelectric focusing. These results were validated with in vitro studies performed with the CHO, HeLa, and HT-29 cell lines, whereas a rabbit ileal loop assay was done to estimate the in vivo action, which confirms the efficacy of 6G in remediation of the choleragenic effects of CT. Thus, 6G can be an effective adjunctive therapy with oral rehydration solution for severe CT-mediated diarrhea.

    Zinc supplementation is a critical new intervention for treating diarrheal episodes in children. Recent studies suggest that administration of zinc along with new low osmolarity oral rehydration solutions / salts (ORS) can reduce the duration and severity of diarrheal episodes for up to three months. Several mechanisms of action of zinc has been proposed, however there is dearth of information about the effect of zinc on intestinal motility during diarrhea. Male albino Wistar rats (80-100g) were used. The effect of different doses of zinc sulphate (25, 50, 100, 150 mg/Kg) on the number of wet faeces was investigated. Intestinal motility during castor oil induced diarrhea was assessed using activated charcoal meal and the mechanisms of action of zinc sulphate on motility were investigated. The effective dose of zinc sulphate (100mg/Kg) significantly reduced (p< 0.001) the number of wet faeces (3.0 ± 0.00) compared with control (6.8 ± 0.25) during diarrhea. This antidiarrheal effect of zinc was abolished by propranolol and nifedipine. Zinc sulphate significantly reduced (p< 0.05) intestinal transit time (60.7 ± 7.13%) compared with control (85.7 ± 2.35%). It is concluded that zinc sulphate reduces the frequency of wet faeces output and intestinal motility during diarrhea via activation of β adrenergic receptor and L-type Ca2+ channel.

    The presence of several high affinity binding sites on human serum albumin (HSA) makes it a possible target for many drugs. This study is designed to examine the effect of Berberine (an ancient Chinese drug used for antimicrobial, antiplasmodial, antidiarrheal and cardiovascular) on the solution structure of HSA using fluorescence, Fourier transform infrared (FT-IR), circular dichroism (CD) spectroscopic methods. The fluorescence spectroscopic results show that the fluorescence intensity of HSA was significantly decreased in the presence of Berberine. The Scatchard's plots indicated that the binding of Berberine to HSA at 296, 303, 318 K is characterized by one binding site with the binding constant is 4.071(±0.128)×10 4, 3.741(±0.089)×10 4, 3.454(±0.110)×10 4 M -1, respectively. The protein conformation is altered (FT-IR and CD data) with reductions of α-helices from 54 to 47% for free HSA to 45-32% and with increases of turn structure5% for free HSA to 18% in the presence of Berberine. The binding process was exothermic, enthalpy driven and spontaneous, as indicated by the thermodynamic analyses, Berberine bound to HSA was mainly based on hydrophobic interaction and electrostatic interaction cannot be excluded from the binding. Furthermore, the displace experiments indicate that Berberine can bind to the subdomain IIA, that is, high affinity site (site II).

    Full Text Available Background. Xyloglucan, a film-forming agent, improves intestinal mucosa resistance to pathologic damage. The efficacy, safety, and time of onset of the antidiarrheal effect of xyloglucan were assessed in children with acute gastroenteritis receiving oral rehydration solution (ORS. Methods. This randomized, controlled, open-label, parallel-group, multicenter, clinical trial included children (3 months–12 years with acute gastroenteritis of infectious origin. Children were randomized to xyloglucan and ORS, or ORS only, for 5 days. Diarrheal symptoms, including stool number/characteristics, and safety were assessed at baseline and after 2 and 5 days and by fulfillment of a parent diary card. Results. Thirty-six patients (58.33% girls were included (n=18/group. Patients receiving xyloglucan and ORS had better symptom evolution than ORS-only recipients, with a faster onset of action. At 6 hours, xyloglucan produced a significantly greater decrease in the number of type 7 stools (0.11 versus 0.44; P=0.027. At days 3 and 5, xyloglucan also produced a significantly greater reduction in types 6 and 7 stools compared with ORS alone. Xyloglucan plus ORS was safe and well tolerated. Conclusions. Xyloglucan is an efficacious and safe option for the treatment of acute gastroenteritis in children, with a rapid onset of action in reducing diarrheal symptoms. This study is registered with ISRCTN number 65893282.

    Probiotics offer remarkable potential for the prevention and management of various infective and noninfective disorders. They are reported to play key roles in the suppression of gastrointestinal infections, antimicrobial activity, improvement in lactose metabolism, reduction in serum cholesterol, immune system stimulation, antimutagenic properties, anticarcinogenic properties, anti-diarrheal properties, and improvement in inflammatory bowel disease. Although probiotic foods are classically confined to beverages and cheese, containing live organisms of the lactic acid bacteria family, such health-promoting foods are traditionally dairy-based, comprising milk and its fermented products. However, recent research focuses on the probiotic potentials of fermented cereal-based beverages which are especially consumed in developing countries characterized by low nutritional security and high incidence of gut pathogen infections. Moreover, lactose intolerance and cholesterol content associated with dairy products, coupled with the vegetarian tendencies of diverse populations in the third world, tend to enforce the recent recourse to nondairy beverages. Probiotic microorganisms are mostly of human or animal origin; however, strains recognized as probiotics are also found in nondairy fermented substrates. This review examines the potentials of some traditional cereal-based beverages to serve as probiotic foods, their microbial and functional properties, as well as their process optimization and storage for enhanced utilization.

    Full Text Available The genus Drimys presents the widest geographical distribution of the Winteraceae family, which comprises seven genera and about 120 species. In Brazil, the genus is found from Bahia to Rio Grande do Sul and occur in two species, Drimys angustifolia Miers, and D. brasiliensis Miers, Winteraceae, popularly known as "casca-de-anta", characterized by the presence of flavonoids and essential oils. It is used in folk medicine as an antiscorbutic, stimulant, antispasmodic, anti-diarrheal, antipyretic, antibacterial, and against asthma and bronchitis, besides having insecticidal properties. In addition to the known biological activities, it is very important to explore new applications in the treatment of physiological disorders or diseases caused by parasites. Based on this information, in this study we propose to evaluate volatile oils of the species D. brasiliensis and D. angustifolia, as an antioxidant, using the model of the DPPH radical as an antiviral against human herpes virus type 1 (HSV-1 and acute toxicity in vivo. The two species were not able to reduce the DPPH radical and showed interesting antiviral activity, significantly reducing the virus titers in vitro assays. Regarding the in vivo toxicity in female Wistar rats, treatment with the two species showed interesting signs in animals such as salivation, ptosis, tremor, decreased motor activity. In addition the oils of D. brasiliensis to other signs, some animals showed increased urination and diarrhea.

    Full Text Available Stevia rebaudiana Bertoni is a small perennial shrub of the Asteraceae (Compositae family that is native to South America, particularly Brazil and Paraguay, where it is known as “stevia” or “honey leaf” for its powerful sweetness. Several studies have suggested that in addition to their sweetness, steviosides and their related compounds, including rebaudioside A and isosteviol, may offer additional therapeutic benefits. These benefits include anti-hyperglycaemic, anti-hypertensive, anti-inflammatory, anti-tumor, anti-diarrheal, diuretic, and immunomodulatory actions. Additionally, critical analysis of the literature supports the anti-bacterial role of steviosides on oral bacteria flora. The aim of this review is to show the emerging results regarding the anti-cariogenic properties of S. rebaudiana Bertoni. Data shown in the present paper provide evidence that stevioside extracts from S. rebaudiana are not cariogenic. Future research should be focused on in vivo studies to evaluate the effects on dental caries of regular consumption of S. rebaudiana extract-based products.

    Dioctahedral smectite (DS) a natural adsorbent clay capable of adsorbing viruses, bacteria, and other intestinal irritants in vitro, is claimed to possess beneficial "antidiarrheal" properties. This study tested the effect of DS on the duration of diarrhea and the frequency and amount of liquid stools. Ninety well-nourished boys, aged 3-24 months, with acute watery diarrhea and mild, moderate, or severe dehydration were included in a randomized double-blind, placebo-controlled trial. After initial rehydration, they received DS or placebo (1.5 g freshly dissolved in 50 ml of water, four times daily for 3 days) along with oral rehydration solution (ORS) and adequate feeding. The clinical characteristics of both groups were comparable on admission. Patients in the smectite group had a significantly shorter duration of diarrhea (mean +/- SD, 54 +/- 16 vs. 73 +/- 13 h) and significantly fewer stools (2.6 +/- 0.8 vs. 3 +/- 0.7 on second day; 1.9 +/- 0.7 vs. 2.4 +/- 0.7 on third day; and 11.3 +/- 3.2 vs. 13.8 +/- 3 overall). The amount of liquid stools was not significantly reduced. Weight gain at 24, 48, and 72 h and on recovery was significantly higher in the smectite group despite the comparable fluid and food intake in both groups. These results suggest a beneficial effect of DS in shortening the duration of diarrhea and reducing the frequency of liquid stools in children rehydrated with ORS.

    Full Text Available Zinc supplementation has been shown to reduce the incidence and prevalence of diarrhea; however, its anti-diarrheal effect remains only partially understood. There is now growing evidence that zinc can have pathogen-specific protective effects. Giardiasis is a common yet neglected cause of acute-chronic diarrheal illness worldwide which causes disturbances in zinc metabolism of infected children, representing a risk factor for zinc deficiency. How zinc metabolism is compromised by Giardia is not well understood; zinc status could be altered by intestinal malabsorption, organ redistribution or host-pathogen competition. The potential metal-binding properties of Giardia suggest unusual ways that the parasite may interact with its host. Zinc supplementation was recently found to reduce the rate of diarrhea caused by Giardia in children and to upregulate humoral immune response in Giardia-infected mice; in vitro and in vivo, zinc-salts enhanced the activity of bacitracin in a zinc-dose-dependent way, and this was not due to zinc toxicity. These findings reflect biological effect of zinc that may impact significantly public health in endemic areas of infection. In this paper, we shall explore one direction of this complex interaction, discussing recent information regarding zinc status and its possible contribution to the outcome of the encounter between the host and Giardia.

    The species Rhus chinensis Mill. (Anacardiaceae) is an important representative of the genus Rhus, which contains over 250 individual species found in temperate and tropical regions worldwide. Rhus chinensis has long been used by folk medicine practitioners in Asia. Leaves, roots, stem, bark, fruit and particularly the galls on Rhus chinensis leaves, Galla chinensis, are recognized to have preventative and therapeutic effects on different ailments (such as diarrhea, dysentery, rectal and intestinal cancer, diabetes mellitus, sepsis, oral diseases and inflammation). However, it is critical to separate evidence from anecdote. Fortunately, recent scientific research has revealed that Rhus chinensis compounds possess strong antiviral, antibacterial, anticancer, hepatoprotective, antidiarrheal and antioxidant activities. Moreover, compounds isolated from the stem of Rhus chinensis significantly suppressed HIV-1 activity in vitro. Compounds from this plant were also found to inhibit enamel demineralization in vitro and enhance remineralization of dental enamel with fluoride. This review highlights claims from traditional and tribal medicinal lore and makes a contemporary summary of phytochemical, biological and pharmacological findings on this plant material. It aims to show that the pharmaceutical potential of this plant deserves closer attention.

    A thiazolidinone CFTR inhibitor(CFTRinh-172) was synthesized by a three-step procedure with trifluromethylaniline as the starting material. The synthesized CFTR inhibitor was characterized structurally by means of 1H NMR and functionally in a CFTR-expressing cell line FRT/hCFTR/EYFP-H148Q by both fluorescent and electrophysiological methods. A large amount(100 g) of high-quality small molecule thiazolidinone CFTR chloride channel inhibitor, CFTRinh-172, can be produced with this simple three-step synthetic procedure. The structure of the final product 2-thioxo-3-(3-trifluromethylphenyl)-5-[4-carboxyphenyl-methylene]-4-thiazolidinone was confirmed by 1H NMR. The overall yield was 58% with a purity over 99% as analyzed by HPLC. The synthesized CFTRinh-172 specifically inhibited CFTR chloride channel function in a cell-based fluorescence assay(Kd≈1.5 μmol/L) and in a Ussing chamber-based short-circuit current assay(Kd≈0.2 μmol/L), indicating better quality than that of the commercial combinatorial compound. The synthesized inhibitor is nontoxic to cultured cells at a high concentration and to mouse at a high dose. The synthetic procedure developed here can be used to produce a large amount of the high-quality CFTRinh-172 suitable for antidiarrheal studies and for creation of cystic fibrosis models in large animals. The procedure can be used to synthesize radiolabled CFTRinh-172 for in vivo pharmacokinetics studies.

    Cocos nucifera (L.) (Arecaceae) is commonly called the "coconut tree" and is the most naturally widespread fruit plant on Earth. Throughout history, humans have used medicinal plants therapeutically, and minerals, plants, and animals have traditionally been the main sources of drugs. The constituents of C. nucifera have some biological effects, such as antihelminthic, anti-inflammatory, antinociceptive, antioxidant, antifungal, antimicrobial, and antitumor activities. Our objective in the present study was to review the phytochemical profile, pharmacological activities, and toxicology of C. nucifera to guide future preclinical and clinical studies using this plant. This systematic review consisted of searches performed using scientific databases such as Scopus, Science Direct, PubMed, SciVerse, and Scientific Electronic Library Online. Some uses of the plant were partially confirmed by previous studies demonstrating analgesic, antiarthritic, antibacterial, antipyretic, antihelminthic, antidiarrheal, and hypoglycemic activities. In addition, other properties such as antihypertensive, anti-inflammatory, antimicrobial, antioxidant, cardioprotective, antiseizure, cytotoxicity, hepatoprotective, vasodilation, nephroprotective, and anti-osteoporosis effects were also reported. Because each part of C. nucifera has different constituents, the pharmacological effects of the plant vary according to the part of the plant evaluated.

    2016-06-01

    Full Text Available Potentilla erecta (PE is a small herbaceous plant with four yellow petals belonging to the Rosaceae family. The rhizome of PE has traditionally been used as an antidiarrheal, hemostatic and antihemorrhoidal remedy. PE contains up to 20% tannins and 5% ellagitannins, mainly agrimoniin. Agrimoniin is a hydrolyzable tannin that is a potent radical scavenger. In this study we tested the anti-inflammatory effect of four PE fractions with increasing amounts of agrimoniin obtained by Sephadex column separation. First, we analyzed in HaCaT keratinocytes the expression of cyclooxygenase-2 (COX-2 induced by ultraviolet-B (UVB irradiation. As COX-2 catalyzes the metabolism of arachidonic acid to prostanoids such as PGE2, we also measured the PGE2 concentration in cell culture supernatants. PE inhibited UVB-induced COX-2 expression in HaCaT cells and dose-dependently reduced PGE2. The PE fraction with the highest agrimoniin amount (PE4 was the most effective in this experiment, whereas fraction PE1 containing mainly sugars had no effect. PE4 also dose dependently inhibited the phosphorylation of the epidermal growth factor receptor (EGFR which plays a crucial role in UVB-mediated COX-2 upregulation. A placebo-controlled UV-erythema study with increasing concentrations of PE4 demonstrated a dose dependent inhibition of UVB-induced inflammation in vivo. Similarly, PE4 significantly reduced UVB-induced PGE2 production in suction blister fluid in vivo. In summary, PE fractions with a high agrimoniin content display anti-inflammatory effects in vitro and in vivo in models of UVB-induced inflammation.

  5. Zinc sensing receptor signaling, mediated by GPR39, reduces butyrate-induced cell death in HT29 colonocytes via upregulation of clusterin.

    Directory of Open Access Journals (Sweden)

    Limor Cohen

    Full Text Available Zinc enhances epithelial proliferation, protects the digestive epithelial layer and has profound antiulcerative and antidiarrheal roles in the colon. Despite the clinical significance of this ion, the mechanisms linking zinc to these cellular processes are poorly understood. We have previously identified an extracellular Zn(2+ sensing G-protein coupled receptor (ZnR that activates Ca(2+ signaling in colonocytes, but its molecular identity as well as its effects on colonocytes' survival remained elusive. Here, we show that Zn(2+, by activation of the ZnR, protects HT29 colonocytes from butyrate induced cell death. Silencing of the G-protein coupled receptor GPR39 expression abolished ZnR-dependent Ca(2+ release and Zn(2+-dependent survival of butyrate-treated colonocytes. Importantly, GPR39 also mediated ZnR-dependent upregulation of Na(+/H(+ exchange activity as this activity was found in native colon tissue but not in tissue obtained from GPR39 knock-out mice. Although ZnR-dependent upregulation of Na(+/H(+ exchange reduced the cellular acid load induced by butyrate, it did not rescue HT29 cells from butyrate induced cell death. ZnR/GPR39 activation however, increased the expression of the anti-apoptotic protein clusterin in butyrate-treated cells. Furthermore, silencing of clusterin abolished the Zn(2+-dependent survival of HT29 cells. Altogether, our results demonstrate that extracellular Zn(2+, acting through ZnR, regulates intracellular pH and clusterin expression thereby enhancing survival of HT29 colonocytes. Moreover, we identify GPR39 as the molecular moiety of ZnR in HT29 and native colonocytes.

    Medications degrade over time, and degradation is hastened by extreme storage conditions. Current procedures ensure that medications aboard the International Space Station (ISS) are restocked before their expiration dates, but resupply may not be possible on future long-duration exploration missions. For this reason, medications stored on the ISS were returned to Earth for analysis. This was an opportunistic, observational pilot-scale investigation to test the hypothesis that ISS-aging does not cause unusual degradation. Nine medications were analyzed for active pharmaceutical ingredient (API) content and degradant amounts; results were compared to 2012 United States Pharmacopeia (USP) requirements. The medications were two sleep aids, two antihistamines/decongestants, three pain relievers, an antidiarrheal, and an alertness medication. Because the samples were obtained opportunistically from unused medical supplies, each medication was available at only 1 time point and no control samples (samples aged for a similar period on Earth) were available. One medication met USP requirements 5 months after its expiration date. Four of the nine (44% of those tested) medications tested met USP requirements 8 months post expiration. Another three medications (33%) met USP guidelines 2-3 months before expiration. One compound, a dietary supplement used as a sleep aid, failed to meet USP requirements at 11 months post expiration. No unusual degradation products were identified. Limited, evidence-based extension of medication shelf-lives may be possible and would be useful in preparation for lengthy exploration missions. Only analysis of flight-aged samples compared to appropriately matched ground controls will permit determination of the spaceflight environment on medication stability.

    Full Text Available Abstract Background Despite its high incidence among children under the age of five, little is known about the burden of pediatric gastroenteritis outside the medical setting. The objective of this study was to describe the burden of acute gastroenteritis among children residing in the United Arab Emirates, including those not receiving medical care. Methods A quantitative cross-sectional survey of 500 parents of children under 5 years of age who had suffered from acute gastroenteritis the preceding three months was conducted in the cities of Abu Dhabi and Al Ain. Data collected included respondent characteristics, disease symptoms, medical care sought, and parental expenditures and work loss. Data were analyzed using parametric and non-parametric statistical methods. Results Vomiting and diarrhea episodes lasted on average between 3 and 4 days. Overall, 87% of parents sought medical care for their children; 10% of these cases required hospitalization with an average length of stay of 2.6 days. When medical care was sought, the average parental cost per gastroenteritis episode was US$64, 4.5 times higher than with home care only (US$14. Nearly 60% of this difference was attributable to co-payments and medication use: 69% of children used oral rehydration solution, 68% antiemetics, 65% antibiotics and 64% antidiarrheals. Overall, 38 parents missed work per 100 gastroenteritis episodes for an average of 1.4 days. Conclusions Given its high incidence, pediatric gastroenteritis has an important financial and productivity impact on parents in the United Arab Emirates. To reduce this impact, efforts should be made both to prevent acute gastroenteritis and to optimize its treatment.

    Full Text Available BACKGROUND: Cynanchum komarovii Al Iljinski is a desert plant that has been used as analgesic, anthelminthic and antidiarrheal, but also as a herbal medicine to treat cholecystitis in people. We have found that the protein extractions from C. komarovii seeds have strong antifungal activity. There is strong interest to develop protein medication and antifungal pesticides from C. komarovii for pharmacological or other uses. METHODOLOGY/PRINCIPAL FINDINGS: An antifungal protein with sequence homology to thaumatin-like proteins (TLPs was isolated from C. komarovii seeds and named CkTLP. The three-dimensional structure prediction of CkTLP indicated the protein has an acid cleft and a hydrophobic patch. The protein showed antifungal activity against fungal growth of Verticillium dahliae, Fusarium oxysporum, Rhizoctonia solani, Botrytis cinerea and Valsa mali. The full-length cDNA was cloned by RT-PCR and RACE-PCR according to the partial protein sequences obtained by nanoESI-MS/MS. The real-time PCR showed the transcription level of CkTLP had a significant increase under the stress of abscisic acid (ABA, salicylic acid (SA, methyl jasmonate (MeJA, NaCl and drought, which indicates that CkTLP may play an important role in response to abiotic stresses. Histochemical staining showed GUS activity in almost the whole plant, especially in cotyledons, trichomes and vascular tissues of primary root and inflorescences. The CkTLP protein was located in the extracellular space/cell wall by CkTLP::GFP fusion protein in transgenic Arabidopsis. Furthermore, over-expression of CkTLP significantly enhanced the resistance of Arabidopsis against V. dahliae. CONCLUSIONS/SIGNIFICANCE: The results suggest that the CkTLP is a good candidate protein or gene for contributing to the development of disease-resistant crops.

    MKT-077, a delocalized lipophilic cation, selectively targets cancer cells. MKT-077 has been reported to inhibit the growth of several tumor types and has undergone phase I clinical testing. We have examined the effect of MKT-077, alone and in combination with the antidiarrheal drug loperamide. Ten human cancer cell lines, four prostate (PC3, DU145, LNCaP, MDA-PCA-2B), two breast (MCF-7 and MDA-MB-231) and four colon (LoVo, Colo320DM, SW1116 and LS174t) were tested in vitro. Cells were grown to confluency prior to treatment. Loperamide potentiated the antiproliferative effect of MKT-077 in all ten cell lines, in a dose-dependent manner. The sensitivity of MDA-PCA-2B cells, the two breast and four colon cancer cell lines to MKT-077 was relatively low (>2.5 microg/ml MKT-077 required to inhibit growth by 95%). In these cell lines, 0.5-5 microg/ml (1-10 microM) loperamide caused a marked increase in the response to MKT-077. Loperamide is known to activate micro-opioid receptors at nanomolar concentrations and block voltage-gated calcium channels at micromolar doses. We found that calcium channel-blockers diltiazem and nifedipine (10-20 microg/ml), as well as tamoxifen (1.5-2.5 microg/ml) can also potentiate the growth-inhibitory effects of MKT-077. These synergistic interactions could be exploited for therapeutic benefit.

    Full Text Available Aim: The roots of the plant Aconitum heterophyllum (EAH are traditionally used for curing hysteria, throat infection, dyspepsia, abdominal pain, diabetes, and diarrhea. Therefore, the present study was undertaken to determine the mechanism involved in the anti-diarrheal activity of roots of A. heterophyllum. Materials and Methods: Ant-diarrheal activity of ethanol extract at 50, 100, and 200 mg/kg p.o. was evaluated using fecal excretion and castor oil-induced diarrhea models, while optimized dose, that is, 100 mg/kg p.o. was further subjected to small intestinal transit, intestinal fluids accumulation, PGE 2 -induced enteropooling and gastric emptying test. To elucidate the probable mechanism, various biochemical parameters and Na + , K + concentration in intestinal fluids were also determined. Further, antibacterial activity of extract along with its standardization using aconitine as a marker with the help of HPLC was carried out. Results: The results depicted a significant (P < 0.05 reduction in normal fecal output at 100 and 200 mg/kg p.o. of extract after 5 th and 7 th h of treatment. Castor oil-induced diarrhea model demonstrated a ceiling effect at 100 mg/kg p.o. with a protection of 60.185% from diarrhea. EAH at 100 mg/kg p.o. also showed significant activity in small intestinal transit, fluid accumulation, and PGE 2 -induced enteropooling models, which also restored the altered biochemical parameters and prevented Na + and K + loss. The extract with 0.0833% w/w of aconitine depicted a potential antibacterial activity of extract against microbes implicated in diarrhea. Conclusion: The study concluded antisecretory and antimotility effect of A. heterophyllum, which mediates through nitric oxide path way.

    探讨分析小儿腹泻合理治疗与药物的临床选择。从治疗效果上分析口服与静脉补液差别不大;在重建胃肠道生物屏障中微生态的药物制剂可起到十分重要的作用;止泻药物的合理应用能缩短患儿的腹泻时间;合理的肠道营养能加速患儿的康复时间。治疗腹泻关键的措施是积极治疗水和电解质紊乱,维持肠道的生态平衡。所以应当把纠正脱水、电解质紊乱作为重点,合理使用微生态调节药物,适时给予肠道营养。%To investigate the reasonable treatment and drug se-lection of infantile diarrhea.Analysis of oral and intravenous rehy-dration is not very different from the treatment effect.Micro eco-logical pharmaceutical preparations play an important role in the reconstruction of gastrointestinal microflora biological barriers. The rational use of antidiarrheal drugs can shorten the duration of diarrhea in children.Reasonable enteral nutrition can accelerate the recovery time of children.The key in treating diarrhea is to adjust of the water and electrolyte disorders and maintain the eco-logical balance of the gut.So it is important to regard the correc-tion of dehydration and electrolyte imbalance as the focus,use the rational microecological regulating drugs and give enteral nutrition in time.

    Diarrhea is the fourth leading cause of child mortality in Ghana. In 2010, Ghana endorsed guidelines from the World Health Organization and the United Nations Children's Fund for use of zinc with low-osmolarity oral rehydration salts (ORS) for the treatment of acute childhood diarrhea. From late 2011 through 2014, the Strengthening Health Outcomes through the Private Sector (SHOPS) project implemented a comprehensive program in 3 regions of Ghana to increase the availability and use of ORS and zinc and to decrease incorrect use of antibiotics and antidiarrheals. The program included (1) partnering with local pharmaceutical firms to introduce and market locally produced zinc products, (2) collaborating with the Ghanaian Pharmacy Council to provide training and supportive supervision of private-sector providers on diarrhea management, and (3) conducting mass media campaigns to raise caregiver awareness. We evaluated the effect of this program using a baseline survey of 754 caregivers of children under 5 with diarrhea at the start of the intervention in 2012 and a follow-up survey of 751 caregivers in 2014. Regression analysis showed that use of ORS with zinc increased from 0.8% in 2012 to 29.2% in 2014 (P<.001), and antibiotic use declined from 66.2% to 38.2% (P<.001) during the same period. The magnitude and statistical significance of these results remained the same after including potential confounding factors as covariates. Inappropriate antibiotic use, however, remained high at follow-up. We conclude that similar programs applied in other settings have the potential to rapidly scale up use of ORS and zinc. Additional efforts are required to reduce persistent incorrect antibiotic use.

    The opioid and nociceptin systems play a crucial role in the maintenance of homeostasis in the gastrointestinal (GI) tract. The aim of this study was to characterize the effect of BU08070, a novel mixed MOP/NOP agonist, on mouse intestinal contractility in vitro and GI motility in vivo in physiological conditions and in animal models mimicking symptoms of irritable bowel syndrome (IBS), including diarrhea and abdominal pain. The effect of BU08070 on muscle contractility in vitro was characterized in the ileum and colon. To assess the effect of BU08070 in vivo, the following parameters were assessed: whole GI transit, gastric emptying, geometric center, colonic bead expulsion, fecal pellet output and time to castor oil-induced diarrhea. The antinociceptive activity of BU08070 was characterized in the mustard oil (MO)-induced abdominal pain model and the writhing test, alone and in the presence of MOP and NOP antagonists. in vitro, BU08070 (10(-10)-10(-6) M) inhibited colonic and ileal smooth muscle contractions in a concentration-dependent manner. in vivo, BU08070 prolonged the whole GI transit and inhibited colonic bead expulsion. The antitransit and antidiarrheal effects of BU08070 were observed already at the dose of 0.1 mg/kg (i.p.). BU08070 reversed hypermotility and reduced pain in mouse models mimicking IBS-D symptoms. Our results suggest that BU08070 has a potential of becoming an efficient drug in IBS-D therapy. Here we also validate mixed NOP/MOP receptor targeting as possible future treatment of functional GI diseases.

    Piperine is the principal alkaloid in black peppers (Piper nigrum L.), which is a commonly included spice in anti-diarrheal formulations. Piperine has antispasmodic activities, but its anti-secretory effect is not known. Therefore, this study investigated the anti-secretory effect of piperine and its underlying mechanism. Piperine inhibited cAMP-mediated Cl- secretion in human intestinal epithelial (T84) cells, similar to black pepper extract. Intraluminal administration of piperine (2 μg/loop) suppressed cholera toxin-induced intestinal fluid accumulation by ∼85% in mice. The anti-secretory mechanism of piperine was investigated by evaluating its effects on the activity of transport proteins involved in cAMP-mediated Cl- secretion. Notably, piperine inhibited CFTR Cl- channel activity (IC50#8'6#10 μM) without affecting intracellular cAMP levels. The mechanisms of piperine-induced CFTR inhibition did not involve MRP4-mediated cAMP efflux, AMPK or TRPV1. Piperine also inhibited cAMP-activated basolateral K+ channels, but it had no effect on Na+-K+-Cl- cotransporters or Na+-K+ ATPases. Piperine suppressed Ca2+-activated Cl- channels (CaCC) without affecting intracellular Ca2+ concentrations or Ca2+-activated basolateral K+ channels. Collectively, this study indicates that the anti-secretory effect of piperine involves the inhibition of CFTR, CaCC and cAMP-activated basolateral K+ channels. Piperine represents a novel class of drug candidates for the treatment of diarrheal diseases caused by the intestinal hypersecretion of Cl-.

Salesi", Ancona, Italy Abstract: Acute gastroenteritis, characterized by the onset of diarrhea with or without vomiting, continues to be a major cause of morbidity and mortality in children in mostly resource-constrained nations. Although generally a mild and self-limiting disease, gastroenteritis is one of the most common causes of hospitalization and is associated with a substantial disease burden. Worldwide, up to 40% of children aged less than 5 years with diarrhea are hospitalized with rotavirus. Also, some microorganisms have been found predominantly in resource-constrained nations, including Shigella spp, Vibrio cholerae, and the protozoan infections. Prevention remains essential, and the rotavirus vaccines have demonstrated good safety and efficacy profiles in large clinical trials. Because dehydration is the major complication associated with gastroenteritis, appropriate fluid management (oral or intravenous is an effective and safe strategy for rehydration. Continuation of breastfeeding is strongly recommended. New treatments such as antiemetics (ondansetron, some antidiarrheal agents (racecadotril, and chemotherapeutic agents are often proposed, but not yet universally recommended. Probiotics, also known as “food supplement,” seem to improve intestinal microbial balance, reducing the duration and the severity of acute infectious diarrhea. The European Society for Paediatric Gastroenterology, Hepatology and Nutrition and the European Society of Paediatric Infectious Diseases guidelines make a stronger recommendation for the use of probiotics for the management of acute gastroenteritis, particularly those with documented efficacy such as Lactobacillus rhamnosus GG, Lactobacillus reuteri, and Saccharomyces boulardii.

    Enteropathogenic Escherichia coli (EPEC) is a major cause of diarrheal disease in young children, yet symptoms and duration are highly variable for unknown reasons. Citrobacter rodentium, a murine model pathogen that shares important functional features with EPEC, colonizes mice in colon and cecum and causes inflammation, but typically little or no diarrhea. We conducted genome-wide microarray studies to define mechanisms of host defense and disease in C. rodentium infection. A significant fraction of the genes most highly induced in the colon by infection encoded CXC chemokines, particularly CXCL1/2/5 and CXCL9/10, which are ligands for the chemokine receptors CXCR2 and CXCR3, respectively. CD11b(+) dendritic cells were the major producers of CXCL1, CXCL5, and CXCL9, while CXCL2 was mainly induced in macrophages. Infection of gene-targeted mice revealed that CXCR3 had a significant but modest role in defense against C. rodentium, whereas CXCR2 had a major and indispensable function. CXCR2 was required for normal mucosal influx of neutrophils, which act as direct antibacterial effectors. Moreover, CXCR2 loss led to severe diarrhea and failure to express critical components of normal ion and fluid transport, including ATPase beta(2)-subunit, CFTR, and DRA. The antidiarrheal functions were unique to CXCR2, since other immune defects leading to increased bacterial load and inflammation did not cause diarrhea. Thus, CXCR2-dependent processes, particularly mucosal neutrophil influx, not only contribute to host defense against C. rodentium, but provide protection against infection-associated diarrhea.

    Full Text Available Drug delivery across the skin is used for several millennia to ease gastrointestinal (GI ailments in Traditional Persian Medicine (TPM. TPM topical remedies are generally being applied on the stomach, lower abdomen, lower back and liver to alleviate GI illnesses such as dyspepsia, gastritis, GI ulcers, inflammatory bowel disease, intestinal worms and infections. The aim of the present study is to survey the topical GI remedies and plant species used as ingredients for these remedies in TPM. In addition, pharmacological activities of the mentioned plants have been discussed. For this, we searched major TPM textbooks to find plants used to cure GI problems in topical use. Additionally, scientific databases were searched to obtain pharmacological data supporting the use of TPM plants in GI diseases. Rosa × damascena, Pistacia lentiscus, Malus domestica, Olea europaea and Artemisia absinthium are among the most frequently mentioned ingredients of TPM remedies. β-asarone, amygdalin, boswellic acids, guggulsterone, crocin, crocetin, isomasticadienolic acid, and cyclotides are the most important phytochemicals present in TPM plants with GI-protective activities. Pharmacological studies demonstrated GI activities for TPM plants supporting their extensive traditional use. These plants play pivotal role in alleviating GI disorders through exhibiting numerous activities including antispasmodic, anti-ulcer, anti-secretory, anti-colitis, anti-diarrheal, antibacterial and anthelmintic properties. Several mechanisms underlie these activities including the alleviation of oxidative stress, exhibiting cytoprotective activity, down-regulation of the inflammatory cytokines, suppression of the cellular signaling pathways of inflammatory responses, improving re-epithelialization and angiogenesis, down-regulation of anti-angiogenic factors, blocking activity of acetylcholine, etc.

    Purpose: Radiotherapy, a cornerstone in the management of head and neck cancer, pelvic cancer, and esophageal cancer is associated with a marked mucosal toxicity. Pain, malnutrition and diarrhea are the most prevalent clinical symptoms of radiation induced mucosal damage. Because there is no known way to obviate radiation mucositis all efforts to prevent aggravation and accelerate healing of mucosal changes are of great importance. Numerous agents including antimicrobials, local and systemic analgesics, antiinflammatory drugs, antidiarrheal drugs, in combination with intensive dietetic care are used to relieve symptoms. Recently coating agents like the polyaluminum-sucrose complex sucralfate were suggested for the prevention and treatment of mucosal reactions. Since sucralfate protects ulcerated epithelium by coating, liberates protective prostaglandins and increases the local availability of protective factors this drug might directly interact with the pathogenesis of mucositis. Patients and Method: The results of available studies are analysed and discussed. Results: The results of several studies indicate that sucralfate treatment especially during radiotherapy for pelvic cancer leads to a significant amelioration of clinical symptoms and morphological changes. An application of sucralfate during radiotherapy of head and neck cancer reveals only limited benefits in most studies performed. Conclusion: Nevertheless sucralfate is a save, cheap and active drug for the prevention and treatment of radiation mucositis especially in patients with pelvic irradiation. (orig.)

    2013-01-01

    Full Text Available Background: Lomotil (diphenoxylate atropine combination has been in use as an antidiarrhoeal agent. Due to presence of opioid (diphenoxylate, there are chances of abuse. The reports of abuse of lomotil have been few in published literature. This chart review aimed to evaluate the characteristics of patients with dependence on lomotil coming to our centre. Materials and Methods: This retrospective chart review was conducted at the Drug De-addiction and Treatment Centre of PGIMER, Chandigarh, India. The records of patients who had presented to the centre with dependence on Lomotil in the last five years were identified, and clinical details were extracted from the records. Results: We identified 41 patients who had presented to our centre with dependence upon lomotil as the primary substance of abuse. The cases were typically married and employed males, educated up to 10 th grade, belonging to a rural Sikh extended or joint family. Most of the patients had taken other opioids too. The number of tablets taken in a day varied from 3- to 250 (median 25. The reasons of initiation were to relieve withdrawals, as a cheap substitute opioid, curiosity, and on suggestion of friends. Conclusion: Lomotil is a medication with a potential of abuse and regulatory controls are required to prevent escalation of misuse of this easily available prescription drug. Lomotil (diphenoxylate and atropine combination has been used since a long time as an anti-diarrheal agent. Reports of abuse of diphenoxylate had surfaced.

    Methotrexate (MTX), a structural analogue of folic acid, is widely used as a chemotherapeutic agent for leukemia and other malignancies. One of the major toxic effects of MTX is intestinal injury and enterocolitis.The mechanism of gastrointestinal toxicity of methotrexate has not been investigated completely. Therefore cancer chemotherapy has to be accompanied by symptomatic therapy such as antibiotics and anti-diarrheal drugs. It is important to investigate the mechanism by which methotrexate induces intestinal damage in order to perform cancer chemotherapy effectively by preventing the side effects. This study aimed at investigating whether nitrosative stress plays a role in methotrexate induced small intestinal damage using a rat model. Adult male rats were administered methotrexate at the dose of 7 mg/kg body weight intraperitoneally for 3 consecutive days and sacrificed 12 or 24 h after the final dose of methotrexate. Vehicle treated rats served as control. The intestinal tissue was used for light microscopic studies and markers of nitrosative stress including tissue nitrite level and nitrotyrosine. Myeloperoxidase (MPO) activity, a marker of neutrophil infiltration was also measured in intestinal homogenates. The villi were damaged at 12 h and the damage progressed and became severe at 24 h after the final dose of MTX. Biochemically, tissue nitrate was elevated fivefold at 12 h and fourfold at 24 h after the final dose of MTX as compared with control. Nitrotyrosine, measured immunohistochemically was detected in all the parts of the small intestine. Duodenum stained the most for nitrotyrosine, followed by ileum and then jejunum. The staining for nitrotyrosine was more intense at 24 h as compared with 12 h after the final dose of methotrexate. There was marked neutrophil infiltration as evidenced by increase in MPO activity in the small intestines. In conclusion, the results of the present study reveal that nitrosative stress may play a critical role in

    Background: European air travelers returning from Algeria, Egypt, Mexico, Morocco, and Tunisia were interviewed about their experience of travelers' diseases upon arrival in Brussels. Diarrhea was mentioned by 37% of the adults and 27% of the children. These subjects were questioned about the types of measures taken, type and duration of drug treatment (if any), and about duration of diarrhea and side effects experienced. Methods: Final analysis was performed based on 2160 interviews. The largest proportion of diarrhea was reported in the age group 15-24 years (46%). Results: The majority of the 2160 subjects had opted for drug treatment (81%): 927 subjects for loperamide alone, 235 for loperamide in combination with nifuroxazide, and 178 for nifuroxazide alone. Other drugs had been used less frequently. The median time to recovery was 2.4 days with loperamide compared to 3.2 days with nifuroxazide and to 3.4 days for the no-treatment group. Conclusions: A stratification of the results by severity of the diarrhea suggests a rank of antidiarrheal potency as follows: loperamide > nifuroxazide > no-drug treatment. The side effect with the highest incidence was constipation (2.4% with loperamide). (J Travel Med 2:11-15, 1995) Travelers' diarrhea is usually defined as the passage of at least three unformed stools per day or any number of such stools when accompanied by fever, abdominal cramping, or vomiting. The definition may be broadened to include more trivial bowel disturbance.1,2 The duration of this self-limited disease generally is 3 to 5 days. Medical intervention aims at shortening the duration of disease, thus allowing the sufferer to resume his or her usual activities at an early stage. A shortened period of recovery to physical well-being has obvious favorable economic implications if the traveler is on business and may help the maintenance of a desired level of quality of life while a traveler is on holiday.

    Full Text Available Kishore Vipperla,1 Stephen J O'Keefe2 1Division of General Internal Medicine, University of Pittsburgh Medical Center, 2Division of Gastroenterology, Hepatology, and Nutrition, University of Pittsburgh School of Medicine, Pittsburgh, PA, USA Abstract: Extensive intestinal resection impairs the absorptive capacity and results in short-bowel syndrome-associated intestinal failure (SBS-IF, when fluid, electrolyte, acid-base, micro-, and macronutrient homeostasis cannot be maintained on a conventional oral diet. Several factors, including the length and site of the resected intestine, anatomical conformation of the remnant bowel, and the degree of postresection intestinal adaptation determine the disease severity. While mild SBS patients achieve nutritional autonomy with dietary modification (eg, hyperphagia, small frequent meals, and oral rehydration fluids, those with moderate-to-severe disease may develop SBS-IF and become dependent on parenteral support (PS in the form of intravenous fluids and/or nutrition for sustenance of life. SBS-IF is a chronic debilitating disease associated with a poor quality of life, and carries significant morbidity and health care costs. Medical management of SBS-IF is primarily focused on individually tailored symptomatic treatment strategies, such as antisecretory and antidiarrheal agents to mitigate fluid losses, and PS. However, PS administration is associated with potentially life-threatening complications, such as central venous thromboses, bloodstream infections, and liver disease. In pursuit of a targeted therapy to augment intestinal adaptation, research over the past 2 decades has identified glucagon-like peptide, an intestinotrophic gut peptide that has been shown to enhance intestinal absorptive capacity by causing an increase in the villus length, crypt depth, and mesenteric blood flow and by decreasing gastrointestinal motility and secretions. Teduglutide, a recombinant analog of glucagon-like peptide-2

    application and performance of these triggers in a teaching hospital. The information on the triggers and ADE were collected through a retrospective chart review of patients discharged from January to June 2008. Four hundred and ninety-seven triggers were identified in 177 charts, and each chart had 2.33 (SD = 2.7 triggers on average. The most frequent triggers were: "antiemetic" (72.1/100 charts, "abrupt cessation of medication" (70.0/100 charts and "over-sedation, drowsiness, numbness, lethargy, hypotension and fall" (34.6/100 charts. The most effective triggers for capturing ADE were "benzodiazepine antagonist", "antidiarrheal" and "rash", which, when identified in charts, were related to an event. The ADE most commonly found were related to the triggers, "abrupt cessation of medication" (8.3/100 charts, "antiemetic" (4.6/100 charts, "rash" and "anti-allergy" (2.1/100 charts.

    Full Text Available Objectives: we analyzed long-term morbidity and bowel function alteration after postoperative radiotherapy for rectal cancer following resection with anastomosis. Patients and methods: thirty-seven patients who underwent surgery with intention to cure and a minimal follow-up period of 3 years were included. These patients were divided into two groups: in the first group, 14 patients received postoperative chemo-radiotherapy, 5-fluorouracil plus folinic acid, and 45 Gy plus 5 Gy boost. In the second group, there were 23 patients regarded as controls. We designed a questionnaire about their bowel function and analyzed the morbidity detected in their follow-up. Results: the group that was treated with postoperative chemo-radiotherapy had more daily bowel movements (p = 0.03 and night-time movements (p = 0.04; incontinence (69.2 versus 17.4% in the control group; p = 0.002, and perianal skin irritation (p = 0.04 versus the control group. Although without meaningful differences, the group under treatment wore a pad more often, had more defecatory urgency, could distinguish worse gas from stool, and needed more frequently antidiarrheal measures. Major complications were present in 28.6% of the under-treatment group: three intestinal resections were performed due to actinic stenosis; one patient had a residual stercoral fistula; another had several occlusive crises solved with medical treatment. Conclusions: postoperative chemo-radiotherapy had a high morbidity rate, which determined a significant alteration in quality of life. Accuracy in indication is therefore necessary, as well as a consideration of other alternatives for treatment, such as preoperative chemo-radiotherapy and total mesorectal excision.Objetivos: analizar la morbilidad y alteración del funcionalismo rectal a largo plazo de la radioterapia postoperatoria tras resección con anastomosis en el cáncer de recto.

    Full Text Available Haridra (Curcuma longa Linn (Zingiberaceae family is a rhizomatous household spice and has been a widely used herb in India since ancient times. Ayurvedic pharmacodynamics of C. longa are described as follows: Rasa - tikta and katu, Guna - rukhsha and laghu, Virya - ushna, Vipak - katu and Doshaghnata - tridoshshamak. It is used as a tonic, carminative, antidiarrheal, hepatoprotective and as a purifying agent. It is also used in cancer management. Since years, haridra has been used as a hemostyptic agent. However, the oncopreventive aspect of haridra has drawn the scientists towards it. Use of haridra in medoja arbuda is documented in Sushrut Samhita. Recently, it has been found that chronic inflammation has played a role in cancer formation. The kapha and vata shamaka property is responsible for the shothghna activity of haridra. Several studies have also proved the anti-inflammatory condition of haridra. The essential oil, containing ar-turmerone, as a major component has been shown to possess anti-inflammatory effect of haridra. Experimental studies ′in vitro and in vivo′ in diverse models have also proved the anti-tumor activity of haridra. Curcumin,the chief ingredient, of it is mainly responsible for anticancer property. However other constituents like Turmerone and polysacchrides also play a major role in anti cancer activity. The free radical scavenging activity as well as inhibition of lipid peroxidation by curcumin has been reported by Kuttan et al. The mechanisms underlying the anticancer potential of curcumin are complex. Many reports in literature mention about that work carried out regarding the suppression of proliferation of cells of different tumors. They include the down regulation of transcription factors, inhibiting COX2, LOX, inducible nitric oxide synthase, matrix metalloproteinases 9, cell adhesion molecules along with TNF-α. Curcumin inhibits TNF-α-induced AKT activation whereby levels required for NFkβ gene

    It is known that medications degrade over time, and that extreme storage conditions will hasten their degradation. The temperature and humidity conditions of the ISS have been shown to be within the ideal ranges for medication storage, but the effects of other environmental factors, like elevated exposure to radiation, have not yet been evaluated. Current operational procedures ensure that ISS medications are re-stocked before expiration, but this may not be possible on long duration exploration missions. For this reason, medications that have experienced long duration storage on the ISS were returned to JSC for analysis to determine any unusual effects of aging in the low- Earth orbit environment. METHODS Medications were obtained by the JSC Pharmacy from commercial distributors and were re-packaged by JSC pharmacists to conserve up mass and volume. All medication doses were part of the ISS crew medical kit and were transported to the International Space Station (ISS) via NASA's Shuttle Transportation System (Space Shuttle). After 568 days of storage, the medications were removed from the supply chain and returned to Earth on a Dragon (SpaceX) capsule. Upon return to Earth, medications were transferred to temperature and humidity controlled environmental chambers until analysis. Nine medications were chosen on the basis of their availability for study. The medications included several of the most heavily used by US crewmembers: 2 sleep aids, 2 antihistamines/decongestants, 3 pain relievers, an antidiarrheal and an alertness medication. Each medication was available at a single time point; analysis of the same medication at multiple time points was not possible. Because the samples examined in this study were obtained opportunistically from medical supplies, there were no control samples available (i.e. samples aged for a similar period of time on the ground); a significant limitation of this study. Medications were analyzed using the HPLC/MS methods described in

    human trials necessary to demonstrate "efficacy" for a beneficial effect on the long term adverse health effects of radiation, such as the development of cancer, cataracts, etc., is expected to take particularly long periods of time. To avoid the long time delay in the development of new drugs as countermeasures for radiation induced adverse health effects, the NSBRI Center for Acute Radiation Research (CARR) is currently focused on the use of drugs that have already been approved for human use by the FDA. Currently there are no approved countermeasures for external radiation exposure by the US Army or by NASA. The appropriate medications for symptoms of the Acute Radiation Syndrome (ARS) due to exposure to solar particle event (SPE) radiation are unknown, but there are medications appropriate for ARS symptoms caused by exposure to conventional ra-diation. The Armed Forces Radiobiology Research Institute (AFRRI) has medical guidelines for ARS medications (http://www.afrri.usuhs.mil/outreach/guidance.htm#policies), as does the US Dept. of Health and Human Services (the REMM (Radiation Event Medical Manage-ment) site (http://www.remm.nlm.gov). Supportive care when ARS symptoms develop include the administration of antimicrobial agents (which can include systemic antibiotics [especially those directed at gram-negative bacteria]), antiemetic agents, antidiarrheal agents, fluids, elec-trolytes, analgesic agents and topical burn creams (Waselenko, J.K. et al. Ann. Intern. Med. 140: 1037, 2004). For nausea and vomiting, serotonin receptor antagonists (5HT3 receptor antagonists) are very effective prophylaxis. There are two drugs that have been approved by the FDA (Zofran and Kytril) for radiation induced nausea and vomiting. Kytril (granisetron) is preferred by the US Army and is currently maintained in the US National Stockpile. Both of these drugs are known to stop retching and vomiting when given either before or after irradi-ation, even when vomiting and/or retching are

    Objective To describe the profile of probiotics utilization in hospitalized pneumonia children and evaluate the ef -fectiveness of probiotics in the treatment of pneumonia in hospitalized children combined with antibiotics. Methods Descriptive data a-nalysis was obtained from the medical records in one children′s hospital in one year period. The clinical data including patient charac-teristics, drug prescribed time, drug use duration, and length of stay was reviewed. Ridit analysis was used to compare the data. Re-sults Data of 2 974 children hospitalized for pneumonia was accessed. Antibiotics were prescribed to 99.1 % ( n=2 948) of pa-tients, probiotics were prescribed to 42.1%(n=1 252) of patients, and both antibiotics and probiotics were prescribed to 41.9%(n=1 246 ). The median of the time to start administration of probiotics was the second day of hospitalization and the mode was the first day of hospitalization. For those patients who were prescribed antibiotics combined with probiotics, the median of the duration of ad-ministration of antibiotics before accepting probiotics was 3 days and the mode was 1 day.After administrating probiotics, the median of the duration of accepting of antibiotics was 5 days, the mode was 4 days, and the median and the mode of the duration of administration of probiotics were 4 days.21%(n=626) of all hospitalized patients were administrated anti-diarrheals.The most common age group of them were neonates and infants (82.3%, n=515).The patients with anti-diarrheal who was administrated antibiotics with or with-out probiotics were 585(47.0%), 34(2.0%), respectively (P0.05).The median of the length of stay in those administrated antibiotics with probiotics was 7 days, the mode was 6 days and the interquartile range was 6-9 days.For those administrated antibiotics without probiotics, the median and the mode of the length of stay were 7 days and the interquartile range was 6-9 days(P>0.05).Conclusion The time of starting to
