Indiscriminate use of chemicals regardless of climate, soil vigor and other factors has adversely affected the environmental quality and soil ecosystem. Fungi play a key role in maintaining the biogeochemical cycles in the soil by utilizing many recalcitrant chemical compounds and some common insecticides. In the present study, many fungal species were isolated from the rhizosphere of Juglans regia L. in the Northern regions of Jammu and Kashmir, India and tested in thisinsecticide utilization-screening programme. Among the isolated strains, only Trichoderma koningii, Penicillium notatum, Aspergillus terricola and A. niger were successful in degrading the supplemented insecticides viz., dimethoate and pyrethroid. The strains exhibited the optimal growth in the temperature range of 20-300C. The two insecticides were providedas the sole source of carbon and nitrogen in the Potato Dextrose Agar (Hi Media). Trichoderma koningii used dimethoate as carbon source at a faster rate compared to that of pyrethroid as the nitrogen source. However, Penicillium notatum andAspergillus niger used dimethoate both as carbon and nitrogen sources. Trichoderma koningii and Aspergillus niger utilized pyrethroid as carbon source more vigorously than Penicillium notatum and Aspergillus terricola.

Metal complexes of general composition [M(L)2]X2 (where M = Cu(II) and X = Cl-, NO3 -) and [M(L)2]X3 (where M = Fe(III) and X = Cl-, NO3 -) were synthesized by the condensation of metal salts with semicarbazone (La)/thiosemicarbazone (Lb) derived from 2-acetyl benzofuran. The ligands and metal complexes were characterized by NMR, elemental analysis, molar conductance, magnetic susceptibility measurements, IR, atomic absorption, and electronic spectral studies. On the basis of electronic, molar conductance and infrared spectral studies, the complexes were found to have tetrahedral geometry. The Schiff bases and their metal complexes were tested for their antioxidant, radical scavenging and antibacterial activities. © 2013.

Objective: The aim of the present work was to assess the total phenolic content (TPC), total flavonoid content (TFC), and total alkaloid content (TAC) of crude hydro-methanolic seed extract of Abrus precatorius L. which is one of the beautiful seed bearing plant belonging to family Fabaceae and used extensively in many Ayurvedic preparations with significant therapeutic significance. Methods: The amount of total phenols was analyzed using Folin–Ciocalteu assay, the amount of total flavonoids by aluminum chloride assay and total alkaloids by bromocresol green-complex assay. Results: The TPC, TFC, and TAC of the hydro-methanolic seed extract were 219.966±4.714 mg gallic acid equivalent per gram, 73.333±2.357 rutin equivalent per gram, and 41.666±4.784 atropine equivalent per gram, respectively. Conclusion: The result of the study highlighted a potent phenol, flavonoid, and alkaloid contents in the crude extract and thus can be used to explore new drugs. The study also justifies some of the medicinal properties of the plant. © 2016, Asian Journal of Pharmaceutical and Clinical Research. All rights reserved.

Dichlorvos, a broad spectrum Organophosphate insecticide is a potential toxic pollutant, adversely affecting the fauna of aquatic ecosystem. The objective of the present work was to evaluate the acute toxicity and behavioral responses of Dichlorvos on Labeo rohita under static conditions. The median lethal concentration of the insecticide was found to be 16.71ppm and one tenth of LC 50 (1.67ppm) was studied for sub acute studies. Data obtained from the Dichlorvos acute toxicity tests were evaluated using Finney's Probit Analysis statistical method. Behavioral patterns were studied in lethal (1, 2, 3 & 4 d) and sublethal concentration (1, 5, 10 & 15 d). The test fish showed erratic swimming, increased surfacing, copious mucus secretion, loss of equilibrium and hitting to the walls of test tank before finally sinking to the bottom just before death. Fish under sublethal concentration were found under stress, but that was not fatal.
