Fruits and vegetables are potential source of natural anticancer agents that protect our body against cancer by scavenging and neutralizing free radicals.\u0000Objective: The study was aimed to explore antioxidant and anticancer properties of methanolic extract of leaves of Hibiscus sabdariffa L. (MEHSL).\u0000Methods: In vitro assays were used to examine the different types of phytochemical content and antioxidant properties of MEHSL. In vitro and in vivo assays were performed to study the effects of MEHSL on Ehrlich ascites carcinoma (EAC) cells. Chemical constituents were also analyzed by GC–MS.\u0000Results: Total phenolic and flavonoid contents of MEHSL were found to be 26.23±0.30 and 131.13±1.40 mg/g of extract in terms of gallic acid and catechin equivalent, respectively. The MEHSL exhibited remarkable scavenging effect on DPPH, ABTS, nitric oxide scavenging activity and inhibition of lipid peroxidation with IC50 values 6.768, 11.54, 29.84 and 17.55, respectively, compared to the positive control, catechin. In vitro cytotoxic study shows that MEHSL reduced the viability of Ehrlich ascites carcinoma (EAC) cells in dose dependent manner. In in vivo, significant inhibition of EAC cells growth and proliferation, reduction of tumor weight and increased of survival time of EAC-bearing mice were noted following by intraperitoneal MEHSL treatment at the doses of 5 and 10 mg/ kg/day (p<0.05). Moreover, the MEHSL also altered the depleted hematological parameters like RBC, WBC, and percentage of hemoglobin (Hb %) of EAC bearing mice towards normal. Furthermore, administration of MEHSL induced apoptosis of EAC cells as observed in Hoechst-33342 stained cells under fluorescence microscope. Hexadecanoic acid, methyl ester (2.845%), hexadecanoic acid (9.858%), linolenic acid methyl ester (2.142%), 9,12- -octadecadien -1-Ol (2.063), alpha-glyceryl linolenate (6.138), arachidic acid (23.280%) and phthalic acid, 6-ethyloct-3-yl 2-ethylhexyl ester (74.926%) were identified as the major constituents of MEHSL by GC-MS analysis.\u0000Conclusion: Findings of the present study suggested that the leaves of H. sabdariffa can therefore be considered as a promising resource in cancer chemotherapy.\u0000Bangladesh Med Res Counc Bull 2021; 47(2): 156-164","PeriodicalId":8704,"journal":{"name":"Bangladesh Medical Research Council Bulletin","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-05-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"41429276","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Culture and sensitivity tests were done for wound swabs and pus samples. Data regarding information of the patients, isolated organisms and culture and sensitivity reports were collected from the records of the department of microbiology.\u0000Results: Out of 1709 samples, 72.0% yielded growth of organisms of which 86.4% were gram negative and 13.6% were gram positive bacteria. Pseudomonas spp was the most commonly (43.8%) isolated organism from both wound swab and pus samples followed by Escherichia coli (16.6%), Staphylococcus aureus (11.8%), Klebsiella spp (9.8%). Among gram negative bacteria, 14.9% were ESBL producing organisms and Klebsiella spp were the most commonly isolated ESBL producers. Most of the bacteria showed high resistance to commonly used antibiotics. Gram negative bacteria were mostly resistant to amoxicillin followed by fluoroquinolones, co-trimoxazole, and cephalosporins whereas colistin, carbapenems and piperacillin/tazobactum were the most effective drugs against them. Majority of gram positive bacteria were resistant to fluoroquinolones and co-trimoxazole but 100% Staphylococcus aureus were sensitive to vancomycin, followed by linezolid (98.0%) and teicoplanin (86.0%) and 32.0% of them were Methicillin resistant (MRSA).\u0000Conclusion: The susceptibility pattern shows that some common antibiotics, especially antibiotics of oral form have very limited usefulness in treatment of infections and also highlight the need for regular reporting and antibiogram guided antibiotic prescription.\u0000Bangladesh Med Res Counc Bull 2021; 47(2): 181-187","PeriodicalId":8704,"journal":{"name":"Bangladesh Medical Research Council Bulletin","volume":"1 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-05-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"69482990","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Multistage sampling method was done and data were collected through face-to-face interview using a pretested questionnaire. Significant factors of COVID-19 prevention behaviour were determined through hierarchical regression and path relationships were explained through causal model.\u0000Results: Almost half of the rural adults showed poor COVID-19 prevention behaviour during the pandemic crisis. Poor knowledge and attitude regarding COVID-19 prevention were also common scenarios in rural areas. Majority of the rural adults were not well motivated and lack of seriousness made them more vulnerable for COVID-19. Socio-demographic and regional variation showed significance predicting health practices of rural adults regarding COVID-19 prevention.
