Susceptibility of microorganism to selected medicinal plants in Bangladesh

ABSTRACTObjectiveTo analyze in-vitro antimicrobial activities of some ethno-pharmacologically significant medicinal plants (methanol extract) against the pathogenic microorganisms (Escherichia coli, Salmonella spp., Bacillus cereus, Staphylococcus aureus, Aspergillus niger and Candida albicans).MethodsThe disc diffusion method was applied for antibacterial test and the poisoned food technique was applied for antifungal test.ResultsThe methanol extract of Terminalia chebula (bark), Phyllanthus acidus (fruits), Sarcochlamys pulcherrima (leaves) and Abelmoschus esculentus (fruits) had significant in vitro antibacterial activity angainst the entire test samples in comparison to standard drug ciprofloxacin. Most of the plant extracts showed low activity against Gram negative bacteria while potential activity against Gram positive bacteria. The antifungal activities of methanol extracts of these plants and standard drug griseofulvin were determined against two pathogenic fungi, and Polygonum lapathifolium (leaves) and Cinnamomum tamala (leaves) showed maximum activity, while Erioglossum rubiginosum (leaves) showed no antifungal activity.ConclusionsFurther chemical and pharmacological investigations are required to identify and isolate chemical constituents responsible for these potential bioactivities and thus to determine their full spectrum of efficacy

Real Estate Industry in Chittagong (Bangladesh): A Survey on Customer Perception and Expectation

Bangladesh is an over populated country and day by day population is increasing rapidly which created the housing problem. Land prices skyrocketed. Due to high price, insufficiency of land, high cost of land registration, and high price of building materials, people are now not interested to buy a land for building their own house. This article shows the customer perception and expectation in different dimensions - budget, types of apartment, size of apartment, favorable location in Chittagong city, favorable facility in an apartment, factors related to purchase decision, factors in selecting developer company, how customers determine about quality, company brand selection, desired services from a particular company, preference between apartment and land, the risk factors perceived by the customers. Geographically, this study focuses on the Chittagong, and can be considered as a little contribution to the understanding of the real estate industry, particularly in Chittagong and particularly from the customer perspective. But the findings may be relevant for other cities also. Real estate companies and developers can take these factors into consideration while making their business strategy and marketing strategy.  On the other hand, Policy makers can take the customer perception and expectation cited in this study, into consideration while making related regulatory policies and framework.

Amphiphilic polymer based nanoformulations of mancozeb for management of early blight in tomato

Not AvailableControlled release (CR) nanoformulations of Mancozeb (Manganese-zinc double salt of N, N-bisdithiocarbamic acid), a protective fungicide, have been developed using poly (ethylene glycols) (PEGs) based functionalized amphiphilic copolymers and evaluated for the management of early blight in tomato. During the field experiment, it was observed that number of infected leaflets/plants were less in developed formulation treated plants as compared to commercial products. Number of infected leaflets per plant was 2.40–4.60 and the number of fruits per plant were 6.40–9.00 at 50 mg L−1, whereas at 100 mg L−1, the corresponding numbers were 2.10-4.10 and 6.30-9.10 respectively. These formulations can be used to optimize the release of Mancozeb to achieve disease control for the desired period depending upon the matrix of the polymer used. Importantly, sufficient amount of active ingredient remains available for a reasonable period of time after application leading to reduced number of applications of pesticide.Not Availabl

Trend of Antimicrobial Use in Food-Producing Animals from 2018 to 2020 in Nepal

Antimicrobial resistance is a global public health problem and is primarily driven by the widespread overuse of antibiotics. However, antimicrobial use data in animals are not readily available due to the absence of a national database in many developing countries, including Nepal. This study was conducted to estimate the quantities of antimicrobials available in Nepal as an indicator of their use in food-producing animals between 2018 and 2020. Data were collected through surveys targeting major stakeholders: (i) the Department of Drug Administration (DDA), the Government of Nepal (GoN) for the authorized antimicrobials for veterinary use in Nepal, (ii) veterinary pharmaceuticals for antimicrobials produced in Nepal, (iii) the DDA and Veterinary Importers Association for antimicrobials bought by veterinary drug importers, and (iv) the Department of Customs, GoN, for antibiotics sourced through customs. Data showed that in the 3 years, a total of 96 trade names, comprising 35 genera of antibiotics representing 10 classes, were either produced or imported in Nepal. In total, 91,088 kg, 47,694 kg, and 45,671 kg of active ingredients of antimicrobials were available in 2018, 2019, and 2020, respectively. None of the antibiotics were intended for growth promotion, but were primarily for therapeutic purposes. Oxytetracycline, tilmicosin, and sulfadimidine were among the most-used antibiotics in Nepal in 2020. Oxytetracycline was primarily intended for parenteral application, whereas tilmicosin was solely for oral use. Sulfadimidine was available for oral use, except for a small proportion for injection purposes. Aminoglycosides, fluroquinolones, nitrofurans, sulfonamides, and tetracyclines were mostly produced locally, whereas cephalosporins, macrolides and “other” classes of antimicrobials were imported. Amphenicols and penicillins were exclusively imported and nitrofurans were produced locally only. In general, except for tetracyclines, the volume of antimicrobials produced locally and/or imported in 2020 was lower than that in 2018, which corresponded to a decreasing trend in total antimicrobials available. Furthermore, the subsequent years have seen a decrease in the use of critically important antibiotics, particularly class I antibiotics. Finally, this study has firstly established a benchmark for future monitoring of antimicrobial usage in food-producing animals in Nepal. These data are useful for risk analysis, planning, interpreting resistance surveillance data, and evaluating the effectiveness of prudent use, efforts, and mitigation strategies

The role of long-term doxycycline in patients of idiopathic pulmonaryfibrosis: The results of an open prospective trial

Objective: To evaluate the effect of long term use of doxycycline in IPF patients. Materials and Methods: Patients of IPF, selected randomly from out patient services and diagnosed on the basis of HRCT chest, were put on doxycycline in an open prospective trial. They were followed up with monitoring of subjective well being along with measurement of pulse rate and arterial oxygen saturation at rest and after a fixed and certain exercise, forced vital capacity, six minutes walk test, St Georges Respiratory questionnaire, and serial chest X-rays. Results: Out of seven patients put on doxycycline, six of them continued the drug for a mean period of 531.43 (± 328.88 days). All the patients tolerated the drug well and had shown uniform subjective and overall objective improvement in all the parameters concerned; the change in the radiological parameter being statistically significant. Conclusion: Doxycycline merits an appropriate clinical trial in the management of idiopathic pulmonary fibrosis. This widely used and relatively safe drug can add a new dimension to the therapeutic regimen. However, further in-depth studies will be required to evaluate its role in the management of IPF

Psychometric properties of Nepalese preschool anxiety scale among preschool children: A cross‐sectional study

Abstract Background The Preschool Anxiety Scale (PAS)‐Parent version scale is a 28‐item measure designed to assess anxiety symptoms in preschoolers aged 3−6 years. The aim of this study was to assess the psychometric properties of the Nepali translated version of the PAS‐Parent version. Methods A descriptive cross‐sectional design was used to collect data from 680 mothers among seven conveniently selected schools in Kathmandu. Results The difference in PAS‐Parent version scores across age groups was found to be statistically significant. In confirmatory factor analysis, 28 items showed a poor fit of the five‐factor original model for the data. However, removing three items (25 item version) through the five‐factor model indicated a better fit. Internal consistency measured by Cronbach's α for the PAS‐Parent version scale was of good range (0.87). Cronbach's α of the subscales: generalized anxiety (0.63), social phobia (0.67), physical injury fears (0.75), and separation anxiety (0.63) were in fair range; while it was in poor range for the obsessive‐compulsive subscale (0.567). Conclusion Nepali version of the PAS demonstrated fair psychometric properties, supporting its utility in screening and assessing a broad range of anxiety symptoms in Nepalese preschoolers

Prevalence of osteoporosis and osteopenia in advanced chronic obstructive pulmonary disease patients

Background: Reduction of bone mineral density (BMD) is a known and established phenomenon in chronic obstructive pulmonary disease (COPD). However, there have been no data regarding osteoporosis/osteopenia in COPD patients in India. Aim: To look for the degree and frequency of osteoporosis/osteopenia in our OPD patients being diagnosed as COPD. Materials and Methods: Thirty-seven randomly selected patients with COPD were assessed for BMD with commercially available ultrasound bone densitometer (HOLOGIC SAHARA) in a pulmonary OPD. Some cofactors for reduced BMD were also noted. Results: Out of the 37 COPD (all belonging to the GOLD III/IV category) patients studied, the BMD was found to be normal in 10 (27%) patients, while 27 (73%) patients were found to have osteopenia/osteoporosis [19 (51.35%) and 8 (21.62%) patients having osteopenia and osteoporosis, respectively]. Conclusion: Frequency of osteoporosis and osteopenia was found to be very high (73%) in our population of advanced COPD. The data suggest a need for further in-depth study regarding the issue
