The work aimed to evaluate the antibacterial activity of Phragmanthera capitata (Loranthaceae) extracts harvested from 03 host plants (Psidium guajava, Cirus sinensis and Theobroma cacao) traditionally used in the treatment of a wide spectrum of diseases. The phytochemical screening of the extracts was determined using standard reference methods. The antibacterial activity of the extracts was evaluated by disk diffusion and liquid microdilution methods on 07 bacterial isolates. Qualitative phytochemical analysis indicated the presence of flavonoids, tannins, sterols, phenols and polyphenols in all extracts of P. capitata. The evaluation of the antibacterial activity showed that the extracts from the stems and haustoria of P. capitata collected from the three host plants are more active than the leaves for all the strains tested. This study shows that P. capitata despite its pernicious character could be a source of useful compounds for the fight against bacterial diseases.

Background: Percutaneous Coronary Intervention (PCI) is the preferred method of revascularization in Acute ST Elevation Myocardial Infarction (STEMI). Aim: Our aim was to study the clinical profile and outcomes of patients who underwent PCI for STEMI at tertiary cardiac centre of Bangladesh. Methods: It is a retrospective, single centre study, performed at Bangabandu Sheikh Mujib Medical University (BSMMU), Dhaka, Bangladesh. All patients who underwent PCI for STEMI from November 2017 to July 2019 were enrolled in this study. All the data were collected from hospital registry and cath lab records. Results: The Study showed that out of 232 patients who presented with STEMI, 74.5% were male with average age of 57.39 years. The mean time of presentation after onset of symptom/s was 17.5 hours. About 66% patients presented in less than 12 hours of symptoms onset, 21% presented at 12-24 hours of symptoms onset and 13% patients presented late. Primary PCI was done in 87% of patients. Almost all patients (98.2%) underwent coronary artery stenting with drug eluting stents. Multivessel PCI during index procedure was done in 7 patients. TIMI III flow following PCI was achieved in 97% cases. Average LVEF at discharge was 44.73%. There were 8 deaths, all after Primary PCI. In-hospital mortality rates for patients presenting with and without cardiogenic shock were 38.46% and 1.59% respectively. The overall mortality rate was 3.98%. Conclusion: This study has reemphasized that PCI is effective in the management of STEMI cases in Bangladesh with improving mortality rates and decreasing complications. Minimizing the delayed presentation after the onset of symptoms should be one of the prime focuses for effective management of STEMI.
