The present study evaluated the hypoglycemic effect of brown algae Sargassum longiotom in alloxan-induced diabetic rats. After the treatment with S. longiotom extract, there is a significant reduction (p<0.001) in blood glucose when compared with the diabetic control group. Moreover the ethanolic extract of S. longiotom significantly reduces (p<0.001) the levels of triglycerides, low-density lipoprotein cholesterol and very low-density lipoprotein cholesterol dose dependent manner. Alternatively, it increases the highdensity lipoprotein cholesterol level in the treated groups. The values of SGOT, SGPT and ALP have been significantly reduced (p<0.001) in the treated rats when compared to diabetic control. Thus the present study indicates that the ethanolic extract of seaweed S. longiotom posses very effective hypoglycemic and hypolipidemic effect on the alloxan induced diabetic rats compared to the reference drug glibenclamide.

Zea mays (maize) and Vigna radiata (green gram) are found to be the chromium (Cr) tolerant and sensitive plants, respectively. In the present paper, we investigate the reduction of the toxicity of Cr in the sensitive plants by the mixed crop cultivation in the field using various amendments. Further, the potassium dichromate was used as the source of hexavalent Cr. The results indicated that Cr adversely affects both the growth and yield of plants. The soil properties vary with Cr and different fertilizer amendments and the yield of both plants were affected by Cr. We conclude that metal accumulation of seeds of green gram was higher than corn and the application of single fertilizer either farm yard manure (FYM) or nitrogen, phosphorous, and potassium (NPK) enhances the growth and yield of both the tolerant and sensitive plants in the mixed crop cultivations.
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.
