Objective:The objective of this study is to evaluate the comparative effect of curcumin and ornidazole in treating chronic periodontitis.Materials and Methods:Twenty individuals of both sexes aged between 27 and 53 years diagnosed with chronic periodontitis and having pocket depths >5 mm bilaterally were selected for this study, in a split-mouth design. Examination of plaque index, probing pocket depth, and clinical attachment level was measured for each patient. The patients received a complete prophylaxis including scaling and root planing after which, both test gels were injected into the two experimental sites chosen, that had probing depth (PD) >5 mm and were located in symmetric quadrants. Pocket PD, clinical attachment loss, and plaque index were recorded at days 0 and 30.Results:At 1-month evaluation, curcumin group showed a significant decrease in pocket PD, plaque index, and clinical attachment loss when compared to the ornidazole group.Conclusion:The results show a more favorable outcome with curcumin than ornidazole gel, thus curcumin can be used as an adjunct to nonsurgical periodontal therapy.
This paper documents the first occurrence of an intergrade form of the highly invasive, South American armoured suckermouth catfish Pterygoplichthys disjunctivus (Weber, 1991) from the brackish waters of the Sundarban Tiger Reserve, West Bengal, India and the exotic Central American cichlid Amphilophus trimaculatus (Gunther, 1867) from Southern Bengal, India. Another species of cichlid Etroplus suratensis (Bloch, 1790) native to Southern India is also recorded for the wild for the first time from West Bengal. Notes on the possible threats due to invasion, sources of introduction, extent of spread and management of these and other invasive species are discussed in the paper.
A lack of current data on Bengal mongoose Herpestes palustris in India inhibits the development of conservation strategies for this endemic wetland mammal. Structured interviews were conducted to assess the threats and examine the ecological importance of the Bengal mongoose in the Nalban fisheries complex in West Bengal for four months (May to August 2017). Over half of the interviewees perceived that the Bengal mongoose faces several threats and that its population has declined over the years. The respondents said that the removal of vegetation is the main reason for the declining mongoose numbers. The ecological importance of the mongoose was apparent among most interviewees. The results suggest that the endemic Bengal mongoose faces multiple anthropogenic hazards and emphasize the critical need for conservation efforts.
A puffer fish, Lagocephalus guentheri Miranda Riberio, 1915, is recorded for the first time from the west coast of India. Three individuals were collected from three different states, Gujarat, Maharashtra and Kerala, with other materials. Brief notes on diagnostic characters of the species and distinction between all species of the genus Lagocephalus in form of a working key to species is presented in this paper.
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.
