Introduction: The breakthrough in the treatment of pathogenic diseases was the unearthing of naturally occurring antipathogenic agents or antibiotics. There have been upsurges in antibiotic-resistant strains of clinically important pathogens, which made way to the emergence of new-fangled bacterial strains that are multi-resistant. The major aim of scientists is to develop new antibiotics or other therapeutic strategies at a pace greater than that at which bacteria are developing resistance. The development of resistance to first-line antimicrobial therapies made way to recommendations for combination therapies for the treatment of some infections and some of this form of chemotherapy seems to be very successful. Objectives: This research was carried out to determine the effect of Kalanchoe crenata extracts on Salmonella typhi load. Also, to assess the potency of the extract of Vernonia amygdalina on Salmonella typhi and finally to ascertain the effect of the combined extract of Kalanchoe crenata and Vernonia amygdalina on Salmonella typhi. Methods: In this research, Salmonella typhi was exposed to a crude extract of Kalanchoe crenata and Vernonia amygdalina and also the combination of the two extracts. Agar wells diffusion method was employed. Results: The combined effect was not sensitive to the Salmonella strain. The Salmonella strain was resistant to V. amygdalina than to K. crenata. K. cranata had the strongest activity against S. typhi with its highest zone of growth inhibition of 20 mm and lowest zone of inhibition of 7 mm while V. amygdalina produced a consistent zone of growth inhibition of 5-6 mm; The combined effect produced a zone inhibition diameter only at the 100 mg/ml with a zone of inhibition value of 14 mm. The subsequent lower concentrations did not show any activity against the microbes. At P-value = 0.05 two-way ANOVA statistics exhibited significant differences amongst the effects produced by the different extracts, though there were no substantial differences in the effects produced by the various concentrations. Conclusion: The Salmonella strain was resistant to V. amygdalina than to K. crenata. At P-value = 0.05 there was a substantial difference in the sensitivity of the bacteria to the different extracts.

Gastrointestinal Conditions

Dadimashtaka choorna is one of the classical ayurvedic polyherbal powder formulation explained in the context of Atisara chikitsa (treatment of gastrointestinal conditions such as diarrhoea), in the text of Astangahridaya. The formulation is mainly indicated for digestive disorders. Even though many researches have brought out the anti-bacterial activity of each component of the formulation, no studies were done to identify the activity of the compound formulation on any specific bacterial strains. Therefore, an attempt was made to accurately understand the action of the preparation against certain selected strains of bacterias. The formulation was prepared according to the classical method of preparation for choorna kalpana. As per the standard norms mentioned in Ayurvedic Pharmacopoeia of India, the concentrated extract of the medicament was prepared. The study was undertaken to evaluate the anti-bacterial activity of concentrated extract of Dadimashtaka choorna against selected microorganisms namely, Salmonella typhi (gram -ve), Escherichia coli (gram -ve), and Bacillus species (gram +ve), using agar well diffusion method and also to compare with the standard drug, ciprofloxacin. It was found that the concentrated extract of Dadimashtaka choorna has significant anti-bacterial activity against the bacterial strain, Bacillus (gram +ve). The study confirmed the anti-bacterial potential of the formulation Dadimashtaka choorna against Bacillus species(gram+ve), which supports the fact that the compound formulation is a promising remedy to curb the gastrointestinal disorders caused by the gram +ve bacterial strains.

Our research work was designed to investigate the curative and preventive effects of Carthamus oxycantha root extract against diarrhea and microorganisms. For the antibacterial experiment, the agar well diffusion method was used against standard bacteria Staphylococcus aureus, Escherichia coli, Pseudomonas aeroginosa, and Salmonella typhi, while for the assessment of antidiarrheal activity, castor oil and the magnesium sulfate-induced diarrhea method was used on albino, laboratory-bred (BALB/c) mice at a dose rate of 200 and 400 mg/kg (body weight, b.w) orally. The methanol extract of C. oxycantha significantly (p < 0.001) decreased the frequency of defecation, and wet stools in a dose depended on the manner of after receiving magnesium sulfate (2 g/kg (b.w)) and castor oil (1.0 mL/mice). Furthermore, the extract of C. oxycantha showed concentration-dependent antimicrobial properties against S. aureus followed by S. typhi, E. coli, and P. aeroginosa bacterial strains, with inhibitions ranging from 10.5–15 mm. These findings show significant results that C. oxycantha is effective as an antidiarrheal and antibacterial agent. However, further works are needed to establish its mode of action.

The aim of the present work was to develop once-daily sustained release microsponges formulations of Nicorandil, a potent potassium channel opener used in cardiovascular diseases and it has low oral bioavailability (70%) and half-life 1 h. So, it is good candidate for sustained release formulations based on microsponge technology. The microsponges were prepared by using quasi-emulsion solvent diffusion method. Scanning Electron Microscopy (SEM) revealed that the microsponges of nicorandil with Eudragit - RSPO and HPMC K100M were smooth, porous, glossy and discrete spherical. The actual drug content and encapsulation efficiency of batch M1 to M9 were obtained in range of 62.05 ± 0.31 to 80.69 ± 0.43 and 64.41 ± 1.71 to 70.58 ± 1.12, respectively. The microsponges formulations were subjected to in-vitro release studies and the results were evaluated kinetically and statically. The best fitted model was found to be Korsmeyer - Peppas model (R2 = 0.9992) for M6 batch.  The ‘n’ value for Korsmeyer - Peppas model was between 0.5 and 1.0 which is indicative of non-Fickian diffusion. Statistical analysis using ANOVA yielded a p value of 0.572 for all the formulations, indicating that there was no significant difference among them.

Objective: In folk medicines, different herbs and plants have been used for many thousands of years .Now it is important to investigate these plants and herbs scientifically which have been used in traditional medicines. The aim of this study was to investigate the antibacterial activity and preliminary phytochemical screening of root of Ipomea turpethum extracted in methanol and its fractions.Methods: The methanol extract was further extracted with three solvents ethyl acetate, chloroform and hexane and analyzed for their antibacterial activity using by agar well diffusion method. They were tested against six bacteria; Echrichia coli, Staphylococcus aureus, Staphylococcus epidermidus, Proteus vulgaris, Pseudomonas auroginosa and Salmonella typhi. The susceptibility of microorganisms to all three fractions was compared with each other and with standard antibotic (Ampicillin). The fractions of Ipomea turpethum was also qualitatively analyzed for the presence of chemical components, i.e. saponins, alkaloids, flavonoids, tannins and glycosides.Result: Among all fractions methanol exhibited highest antibacterial activity (average zone of inhibition 23.53mm ± 1.3) while ethyl acetate exhibited least antibacterial activity (average zone of inhibition 18.50mm ± 3.5). Minimum inhibitory concentration of methanol, ethyl acetate, chloroform and hexane fractions was found in the range of 650ug/ml to 2500ugl/ml against microorganisms.Conclusion: Results obtained from this preliminary in-vitro experiment indicate that, all three fractions of Ipomea turpethum has good antibacterial activity against all microorganisms used. By phytochemical analysis of extract, it has been found to contain some nutrient and chemical components which support its ethenomedicinal use but further work is required for development of new antibiotic compounds.Bangladesh Journal of Medical Science Vol.17(1) 2018 p.93-97
