Analgesic and anti-inflammatory activities of Alocasia indica (Roxb.) Schott
Atiqur Rahman,M. Solaiman,Ekramul Haque,A. K. Das 경희대학교 융합한의과학연구소 2011 Oriental Pharmacy and Experimental Medicine Vol.11 No.3
The ethanol extract of the dried rhizome of Alocasia indica (Roxb.) Schott. (Family - Araceae) was investigated for its possible analgesic and antiinflammatory activities in animal models. The extract showed significant (P<0.001) writhing inhibition in acetic acid-induced writhing in mice at the oral dose of 300 and 600 mg/kg of body weight comparable to the standard drug diclofenac sodium at the dose of 25 mg/kg of body weight. Moreover, when given orally to rats at dose of 300 and 600 mg/kg of body weight, the extract showed a significant (P<0.001) anti-inflammatory activity against carrageenin induced paw edema in rats which was comparable to the standard drug aspirin at the dose of 150 mg/kg of body weight. The overall results tend to suggest the analgesic and anti-inflammatory activities of the crude ethanolic extract of dried rhizome of Alocasia indica (Roxb.) Schott. The obtained results provide a support for the use of this plant in traditional medicine and its further investigation.

Different types of milk products, such as kwacha golla, mawa, cheese, curd, and chocolate are popular in Bangladesh. However, the microbiological safety of these products is poorly understood. This study was performed to assess the microbiological quality of kwacha golla, a local milk product. Kwacha golla samples were collected from ten different areas of Rajshahi and Kushtia regions, and the quality of the each sample was assessed using various parameters including standard plate count, total coliform, fecal coliform, total fungi, and spore-forming bacteria, as well as food-borne microorganisms. Out of 300 samples, total coliform was detected at 56.66% (n= 300), exceeding the minimum allowable limit of 36.66%. Similarly, experiments were carried out with fungi and food-borne pathogens including Escherichia coli, Listeria monocytogenes, Salmonella sp., and Staphylococcus aureus. Results revealed 85.33, 53, and 49.33% of the samples were contaminated by fungi, E. coli, and L. monocytogenes, respectively. However, all samples showed no contaminations of Salmonella sp. and Staphylococcus sp. Therefore, this study could be helpful to the people of Bangladesh by providing information on the possibility of a major health problem caused by the consumption of kwacha golla.

Action and activity representation and recognition are very demanding research area in computer vision and man-machine interaction. Though plenty of researches have been done in this arena, the field is still immature. Over the last decades, extensive research methodologies have been developed on human activity analysis and recognition for various applications. This paper overviews various recent methods for human activity recognition with analysis. We attempt to sum up the various methods related to human motion representation and recognition. We make an effort to categorize the recent methods from the best in the business, and finally figure out the short-comings and challenges to dig out in future to develop robust action recognition approaches. This work exclusively endeavors to encompass the researches related only to human action recognition mainly from 2001 till-to-date with critical assessment of the methods. We also present our work along with to solve some of the shortcomings. It will widely benefit the researchers to understand and compare the related advancements in this area.
