RESUMO
Background: Ischemic Cerebrovascular stroke is one of the largest cause of death and disability. It is usually caused by thrombosis or thromboembolic phenomena. Large platelets are more reactive, produce more prothrombotic factors and aggregate more easily, and can be a major risk factor/indicator for stroke. While the Mean Platelet Volume (MPV) has been studied in detail in cases of IHD, very few studies have been done in stroke, and none in India � prompting this study. We aim to determine whether an association exists between MPV and incidence/severity of stroke.Methods: The study was carried out among fifty patients with an acute ischemic stroke. Clinical severity was assessed using Modified Rankin憇 scale. MPV was measured using an automated analyzer. Fifty controls were recruited and analysed.Results: MPV has got a statistically significant correlation with Ischemic stroke with a p value of < 0.0001. Average MPV in cases was 9.78+1.25 fl vs. controls who average 8.30+1.14 fl. We did not find a statistically significant correlation between clinical severity of stroke and MPV (P = 0.550).Conclusions: This study has shown an elevation of MPV in acute phase of Ischemic stroke. Within this relationship and adjusting for other significant variables in multivariate regression analysis, it can be stated that an increase in MPV is independently associated with stroke. Further research is required into the role of platelet volume in stroke pathology, outcome, and, most importantly, in individuals at risk for stroke.
RESUMO
The incessant and vital need to discover new antimicrobial compounds with diverse chemical structures and novel mode of action is stimulated by the increasing failure of chemotherapeutics and expanded antibiotic resistance exhibited by pathogenic agents. In the present research work, antimicrobial activity of few plant extracts and ayurvedic samples were screened against bacteria. Phytochemical analysis of active plant extracts showed the presence of triterpenes, glycosides and flavonoids. Both aqueous and acetone extracts of Holoptelia integrifolia leaf and Barringtonia acutangula flower; and methanolic extract of Glycyrrhiza glabra and Meera powder exhibited activity against S. aureus. Aqueous mortar pestle and soxhlet extracts of B. acutangula flower exhibited activity against both P. aeruginosa and E. coli. Further, the ability to adhere and build biofilm was assessed in few biofilm formers at sub-MIC concentrations using the Microtiter plate assay and the Coverslip assay. Aqueous soxhlet and mortar pestle extract of B. acutangula flower and acetone overnight extract of H. integrifolia leaf exhibited antibiofilm activity against these organisms.
