<p>This study evaluates the antidiarrheal activity of <em>Rumex vesicarius</em> (leaf) by using in vitro and in vivo assays. Antidiarrheal effect of <em>R. vesicarius</em> was  evaluated using castor oil-induced diarrhea model in rat. Weight and  volume of the intestinal content were assessed using the enteropooling method. Atropine (3 mg/kg, i.p) was used as positive control. <em>R. Vesicarius</em> at the  doses of 200 and 400 mg/kg p.o. significantly retarded castor oil-induced  enteropooling and intestinal transit. The gastrointestinal transit rate was  studied and <em>R. vesicarius</em> at the doses of 200 and 400 mg/kg significantly inhibited (p&lt;0.001) weight and volume of intestinal content. <em>R. vesicarius</em> caused concentration-dependent (0.01–1 mg/mL) relaxation of spontaneous contractions in isolated rabbit jejunum tissue preparation and inhibited K<sup>+</sup>-80 induced contractions (0.01-5 mg/mL), similar to verapamil, suggestive of calcium channel blockade. Results obtained herein indicate that <em>R. vesicarius</em> may contain effective compounds which can be used as an antidiarrheal agent.</p>

Ficus Palmata

Abstract Background Ficus palmata (Fig), are distributed in different parts of the world, and are used in traditional medicine to treat various ailments including inflammation, tumor, epilepsy, jaundice, influenza and bacillary dysentery. The present study aimed to evaluate the antidiarrheal, antisecretary, antispasmodic, antiulcer and anti motility properties of Ficus palmata. Methods In-vivo, in-vitro and in-silico techniques were used to investigate various gastrointestinal effects of Ficus palmata. Antidiarrheal, antisecretary, antispasmodic, antiulcer, anti motility and molecular docking were performed using castor oil induced diarrhea and fluid accumulation, isolated tissue preparations, ethanol-HCl induced ulcer assay, charcoal meal transit time and Auto Doc Vina. Results Ficus palmata crude extract (Fp.Cr) exhibited protection against castor oil-induced diarrhea in mice and dose-dependently inhibited intestinal fluid secretions. Fp.Cr caused relaxation of spontaneous and K+ (80 Mm)-induced contractions in isolated rabbit jejunum preparations. It showed protective effect against gastric ulcers induced by ethanol-hydrochloric acid in rats. Fp.Cr reduced distance travelled by charcoal meal in the gastrointestinal transit model in mice. The plant constituents: psoralenoside and bergapten showed high binding affinities (E-value ≥ − 6.5 Kcal/mol) against histaminergic H1, calmodulin and voltage gated L-type calcium channels, while showed moderate affinities (E-value ≥7 Kcal/mol) against dopaminergic D2, adrenergic α1, muscranic M3, mu-opioid, whereas revealed lower affinities (E-value ≥9.5 Kcal/mol) vs. muscranic M1, histaminergic H2 and H+/K+ ATPase pump. Germanicol acetate and psoralene exhibited weak affinities against aforementioned targets. Conclusion This study reveals that Ficus palmata possesses anti-diarrheal, anti-secretory, anti-spasmodic, anti-motility and anti-ulcer activities. The various constituents reveal different binding affinities against target proteins, which mediate the gastrointestinal functions.

<p class="Abstract">In this study the antidiarrheal activity of ethanolic extracts of the leaves of <em>Mikania cordata</em> and <em>Litsea monopetala</em> was evaluated. Diarrhea was induced in mice by oral administration of castor oil (0.5 mL) 30 min after the administration of the extracts. During a 4 hour study the number of diarrheal feces and percentage inhibition of the extracts (200 and 400 mg/kg body weight) was determined. Loperamide (3 mg/kg body weight) served as standard and belonged to the positive control group. The extracts exhibited potent antidiarrheal activity as well as achieved statistically significant p value (p&lt;0.01 and p&lt;0.05) compared to control group. Among the extracts the highest percentage inhibition of defecation (60%) was recorded for leaf extract (400 mg/kg body weight) of <em>L. monopetala</em>. So, the study corroborates the significant antidiarrheal activity of <em>M. cordata</em> and <em>L. monopetala</em> leaf extracts and raises the demand of further sophisticated investigation.</p><p> </p>

Three in vitro tissue preparations were used to derive kinetic parameters for the transport of D-glucose in rabbit jejunum, and the resistance of the unstirred water layer was varied by altering the rate of stirring of the bulk phase. The apparent permeability coefficient (Pd*) of the rabbit jejunum for D-glucose was much higher from everted sacs and full-thickness biopsies than from intestinal discs. Failure to adjust the experimentally determined flux for the contribution of the passive component led to errors in the estimation of the maximal transport rate (Jdm) and in the apparent Michaelis constant (Km*). Jdm was higher in biopsies than everted sacs or discs, Km was also higher in biopsies. With each tissue preparation Km* and Pd* were markedly influenced by stirring the bulk phase, whereas Jdm was unchanged. The results indicate that failure to account for the effect of the passive component and the unstirred layer leads to major errors in the estimation of Km*, Pd*, and Jdm. Furthermore, the magnitude of these kinetic constants is influenced by the type of in vitro system used to derive the constants, and it is therefore invalid to extrapolate the results obtained using one preparation to those utilizing another preparation, or to the in vivo situation.

The leaf of Osyris quadripartita is traditionally used for the management of diarrhea in different parts of Ethiopia. However, its use has not been scientifically validated for its efficacy. The aim of this study was to investigate antidiarrheal activity of hydroalcoholic leaf extract of O. quadripartita in mice models. Different doses of the methanolic leaf extract of O. quadripartita (100, 200, and 400 mg/kg) were tested for antidiarrheal activity using castor oil–induced diarrhea, enteropooling, and gastrointestinal motility models in Swiss Albino mice. The activities of the extract at different doses were compared with standard drugs and negative control groups of mice. The extract at all tested doses resulted in significant reduction ( P < .01) in number of wet feces, whereas significant reduction ( P < .01) in frequency of defecation in castor oil–induced diarrhea was seen at a dose of 400 mg/kg. It also showed a dose-dependent and significant reduction of volume of intestinal content in the enteropooling model at all tested doses and the observed results in 200 and 400 mg/kg were better than the standard drug, loperamide. However, significant antimotility effect was not observed at any of the tested doses. From these results we can conclude that methanolic leaf extract of O. quadripartita showed antidiarrheal activity.

Traditionally people used Dodonaea viscosa for the treatment of various ailments, including diarrhea. Therefore, this study was aimed to evaluate the antidiarrheal activity of the 80% methanolic leaf extract of D viscosa against castor oil-induced diarrhea in mice models. Different doses of 80% methanolic leaf extract of D viscosa (100, 200, and 400 mg/kg) were evaluated for their antidiarrheal activities using castor oil–induced diarrhea, gastrointestinal transit, and enteropooling models in Swiss albino mice. At all test doses, the plant extract showed significant ( P < .05) inhibition in the frequency of defecation of wet feces and total fecal output as compared to the control group. Similarly, at all dose ranges used the plant extract demonstrated significant ( P < .05) reduction in an intraluminal fluid accumulation as compared to the untreated group. Besides, at higher doses, the plant extract also indicated significant ( P < .05) antimotility activity in comparison with the control. In conclusion, these findings illustrated that the 80% methanolic leaf extract of D viscosa supported the traditional claim of antidiarrheal activity of the plant though further investigations are warranted.

Objective. This in vitro and in vivo study was conducted to rationalize some of traditional medicinal uses of Ailanthus altissima in gastrointestinal, respiratory, and cardiovascular systems. Materials. Crude extract of Ailanthus altissima (Aa.Cr) and its fractions were prepared and utilized in in vitro and in vivo studies. For in vitro studies, Aa.Cr was investigated on isolated rabbit jejunum, isolated tracheal strip, and isolated aorta of rat suspended in tissue organ bath. Platelet rich and platelet poor plasma were used to study platelet aggregation inhibitory activity. In vivo antidiarrheal effect of Aa.Cr was investigated on balb/c mice pretreated with castor oil to induce diarrhea and SD rats were used to study hypotensive activity. Results. Concentration dependent spasmolytic effects of Aa.Cr and its DCM fraction (Aa.DCM) were observed on spontaneous and spasmogen induced contractions in jejunum isolated from rabbit, but effect against high potassium (high-K+) induced contractions was more potent. Moreover Aa.Cr showed parallel shifting of calcium response curve to the right side. While its aqueous fraction (Aa.aq) caused spasmogenesis of isolated rabbit jejunum, this effect was blocked partially with prior administration of atropine (1μM). Concentration dependent protection against castor oil induced diarrhea was also observed. Relaxant effect was observed by the application of Aa.Cr and Aa.DCM against high-K+ and carbachol (CCh) induced contractions in tracheal strips isolated from SD rats, while Aa.Aq caused partial relaxation of high-K+ induced contractions, but no effect was observed against CCh induced contractions. Relaxation of rat aorta by the application of Aa.Cr and its fractions was also observed. Inhibition of force of contraction in rabbit atrium was also observed. Inhibition of platelet aggregation was observed against epinephrine and ADP induced aggregation. Conclusion. Keeping in view the observed results, it is concluded that smooth muscle relaxant, platelet aggregation inhibitory and hypotensive effect may be due to the blockage of calcium channels.

Background: Many plants and herbs have been shown to possess antidiarrheal, antispasmodic, and antimicrobial activities. The present study was developed to determine the possible antidiarrheal and antispasmodic effects of methanolic extract of Peganum harmala L. (MEPH) in diarrhea and hyperactive gut. Methodology: The crude MEPH was studied using the in-vivo castor oil-induced diarrhea model in mice, while isolated rat ileum was used in the in-vitro studies. Antimicrobial efficacy of MEPH was tested against different bacterial strains (Staphylococcus aureus, Bacillus subtilis, Escherichia coli, Klebsiella pneumonia), Yeast (Candida albicans) and Fungus (Aspergillus niger) using in-vitro assays. Results: In the castor oil-induced diarrhea, MEPH at 100 and 200 mg/kg showed 40% and 80% protection in mice while positive control drug, loperamide showed 100% protection. In the in-vitro experiments, MEPH dose-dependently (0.01 to 0.3 mg/mL) inhibited carbachol and high K+-induced contractions at comparable EC50 values similar to papaverine, a phosphodiesterase (PDE) inhibitor. The PDE inhibitory like effect was further confirmed when pre-incubated ileum tissues with MEPH (0.1 and 0.3 mg/mL) shift the isoprenaline-mediated inhibitory CRCs against carbachol to the left, similar to papaverine. In antibacterial assay, MEPH showed efficacy against two Gram positive bacteria (S. aureus, and B. subtilis) and one Gram negative bacteria (E. coli). But extract didn’t show any effect against K. pneumoniae. The MEPH also showed efficacy against fungal strain (A. niger) and yeast strain (C. albicans). Conclusions: MEPH shows antidiarrheal and antispasmodic effects because of its antimotility effect which were possibly due to the inhibition of PDE enzyme. The study has shown an optimal antimicrobial activity of MEPH as all bacteria, yeast and fungal strains were found sensitive except K. pneumoniae. MEPH proved efficacy against both enteric and non-enteric pathogens causing diarrhea, thus confirming its role in both the infectious and non-infectious diarrhea.

Background: Snakebite envenomation is a global priority ranked top among other neglected tropical diseases. There is a folkloric claim that Uvaria chamae is beneficial for the management of snakebite and wounds in African ethnobotanical surveys. Besides, there are many registered patents asserting the health benefits of U. chamae. Objective: This study aimed to investigate U. chamae’s potentials and identify candidates for the development of tools for the treatment and management of N. nigricollis envenomation. Methods: Freshly collected U. chamae leaves were air-dried, powdered, and extracted in methanol. The median lethal dose of the extract was determined and further fractionated with n-hexane, n-butanol and ethyl acetate. Each fraction was tested for neutralizing effect against venom-induced haemolytic, fibrinolytic, hemorrhagic, and cytotoxic activities. Results: U. chamae fractions significantly (p<0.05) neutralized the haemolytic activity of N. nigricollis venom in n-butanol; 31.40%, n-hexane; 33%, aqueous residue; 39.60% and ethyl acetate; 40.70% at the concentration of 100mg/ml of each fraction against 10mg/ml of the snake venom when compared to the positive control. The fibrinolytic activity of N. nigricollis venom was significantly (p<0.05) neutralized in n-hexane at 73.88%, n-butanol; 72.22% and aqueous residue; 72.22% by the fractions of U. chamae. In addition, haemorrhagic activity of N. nigricollis venom was significantly (p<0.05) neutralized by U. chamae fractions at the concentrations of 100mg/ml, 200mg/ml and 400mg/ml except for n-butanol and aqueous residues at 400 mg/ml. Conclusion: U. chamae leaves fractions possess a high level of protection against N. nigricollis venoms-induced lethality and thus validate the pharmacological rationale for its usage in the management of N. nigricollis envenomation.

AbstractSelf-nanoemulsifying drug delivery systems (SNEDDS) were used to enhance the dissolution rate of furosemide as a model for class IV drugs and the system was solidified into liquisolid tablets. SNEDDS of furosemide contained 10% Castor oil, 60% Cremophor EL, and 30% PEG 400. The mean droplets size was 17.9 ± 4.5 nm. The theoretical model was used to calculate the amounts of the carrier (Avicel PH101) and coating materials (Aerosil 200) to prepare liquisolid powder. Carrier/coating materials ratio of 5/1 was used and Ludipress was added to the solid system, thus tablets with hardness of 45 ± 2 N were obtained. Liquisolid tablets showed 2-folds increase in drug release as compared to the generic tablets after 60 min in HCl 0.1 N using USP apparatus-II. Furosemide loaded SNEDDS tablets have great prospects for further in vivo studies, and the theoretical model is useful for calculating the adequate amounts of adsorbents required to solidify these systems.
