During the previous few decades, it has been seen that there is a rapid emergence of pathogens resistant to multiple antibiotics. This has now become a global crisis. Some unexplored or less explored plants also provide some antibacterial, bactericidal and antioxidant properties. The antibacterial, bactericidal effects of extracted essential oils (EEOs) of Thunbergia coccinea, Acacia polyacantha, Polygonum micrpcephallum, Abies spectabilis and Clerodendrum colebrookianum was tested in comparison with standard antibiotics. The methods chosen were disc diffusion and deduction of minimum inhibitory concentration (MIC) by microbroth dilution assays of the EEOs against the bacterial strains.The antioxidant activity was found out utilizing DPPH free radical scavenging assay, MDA, Hydrogen peroxide radical inhibition assay and Superoxide radical inhibition assay (O 2 -). Some commonly used standard antibiotics (metronidazole, amoxicillin, clarithromycin, rifampicin, clindamycin and oxacillin,) were utilized to compare the EEO antibacterial action. Clerodendrum colebrookianum (85.17 ± 3.06 µg MDA/g extract) had a reasonable MDA. Acacia polyacantha in MIC had values of 3.86 ± 0.25 to 6.20 ± 0.16. Polygonum micrpcephallum had excessive H2O2 (48.27 ± 2.4 5%). The antibacterial actions determined by the paper disc‑diffusion technique of the EEO extracted from these plants showed that most had some antibacterial actions. Also, it was seen that the bactericidal action of the EEO extracted from E. alba was most potent against S. pyogenes (4.06 ± 0.15). The extract of the plant at varying concentrations (20, 40, 60, 80 and100 mg/mL) demonstrated noteworthy (P< 0.001) anthelmintic action in an effective change when the dose was adjusted. In conclusion, most of the tested plants contain a medicinal value, which can be utilized in the future to supplement artificial medicines and cure emerging diseases that create havoc for mankind.
This article studies the situation of health awareness among the inhabitants of Chars (river islands) of Nalbari, Borpeta and Jorhat districts of Assam. The health awareness is measured by health expenditure. The findings reveal that all the variables—caste-residence compound status, educational attainment, economic consideration of the family, family structure and primary occupation of the families have desirable impact on health awareness. In particular, the inhabitants of Char areas of Nalbari and Borpeta districts are seen to be least health aware. Thus on the basis of the findings of this study, it can be stated that in spite of launching several schemes for the upliftment of Chars (like forming Char area development authority, forming a separate state ministry for Char development, and so forth), the people living in these Chars are still far more backward than the people living in other parts of Assam.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
