Antimutagenic effect of dioscorea pentaphylla on genotoxic effect induced by methyl methanesulfonate in the Drosophila wing spot test.

Objectives: Plants as dietary sources are known to have several chemoprotective agents. Dioscorea pentaphylla is an important medicinal plant, which is often used as edible food. This study was undertaken to evaluate the antigenotoxic potential of D.

Protective effect of caffeine on ethyl methanesulfonate-induced wing primordial cells of Drosophila melanogaster.

Objectives: The antimutagenic effect of caffeine is evaluated against ethyl methanesulfonate (EMS)-induced mutation rate in Drosophila.

Materials And Methods: The mutation rate is evaluated using wing mosaic assay. In transheterozygous larvae, multiple wing hair (mwh 0.

Studies on Oecophylla smaragdina as a bio-control agent against pentatomid bug infesting on Pongamia tree.

Weaver ants, (Oecophylla smaragdina) have been found to predate on pentatomid bug (Cyclopelta siccifolia) infesting Pongamia pinnata tree in mid-western Ghat region of Shimoga district, Karnataka. The present study was undertaken to evaluate the potential of weaver ants, that are abundant on P. pinnata trees, to control the pentatomid bugs.

Bio-efficacy of Dioscorea pentaphylla from Midmid-Western Ghats, India.

Antibacterial and antifungal activity of crude extracts of medicinally important and traditionally used yam plant, Dioscorea pentaphylla, from mid-Western Ghats was evaluated against 27 bacterial and 5 fungal clinical strains collected of the patients from infectious sources. The clinical strains belonging to their respective species showed concentration-dependent susceptibility toward crude petroleum ether extract, chloroform extract and methanol extract at 100 μg/100 μl. The extracts exhibited predominant antibacterial activity against Staphylococcus aureus (ATCC-20852), Pseudomonas aeruginosa (ATCC-29737) and Klebsiella pneumoniae (MTCC-618), respectively, and five clinically isolated pathogenic fungi, Trichophyton rubrum, Microsporum gypseum, Tricophyton tonsurans, Microsporum audouini, and Candida albicans, with antibacterial drug ciprofloxacin and antifungal drug fluconozole (50 μg/100 μl) as standards.

Modulation in the protein metabolism by subacute sodium cyanide intoxication in the freshwater fish, Labeo rohita (Hamilton).

The effects of exposure to one-third and one-fifth sublethal concentrations (0.106 and 0.064 mg/L) of sodium cyanide on protein metabolism on freshwater carp, Labeo rohita, was studied.
