Twelve extracts obtained from nine plants belonging to six different genera of Clusiaceae were analyzed against Gram-negative (Escherichia coli and Pseudomonas aeruginosa) and Gram-positive (Staphylococcus aureus and Enterococcus faecalis) bacteria using the microdilution broth assay. Tovomita aff. longifolia, T. brasiliensis, Clusia columnaris, Garcinia madruno, Haploclathra paniculata, and Ca...

Saline lakes provide a prey-rich, predator-free environment for birds to utilize during migration and stopover periods. The Great Salt Lake (GSL), Utah is the largest salt lake in North America and is utilized by millions of migratory birds. It also is host to multiple commercial endeavors. Proposed expansion of commercial use of the GSL would result in increased impounded area and water extrac...

Many plants are used for ethnoveterinary purposes in South Africa, particularly in rural areas. Extracts of 17 plant species employed to treat infectious diseases were prepared using three solvents and the antibacterial activity of the extracts was determined against two Gram-positive and two Gram-negative bacteria. Anthelmintic activity was evaluated against the free-living nematode Caenorhabd...

The methanol extract of Cassia fistula seeds was investigated for potential antimicrobial activity against medically important bacterial, yeast and fungal strains. The antimicrobial activity was determined in methanol extract using the disk diffusion technique and the broth dilution method. The extract was effective on tested microorganism and the minimum inhibitory concentration (MIC) values w...

Objective of the study is to screen for in vitro pharmacological activities of 5-Lipoxygenase and cytotoxicity of using methanolic callus extracts of Biophytum sensitivum. In vitro Brine shrimp lethality assay was carried out according to the method of Meyer et al., (1982) and the lipoxygenase inhibition activity was assayed using photometric method as described by Reddanna et al., (1985). The ...

BACKGROUND Saururus cernuus (Sc) is a small plant, used for the treatment of various human inflammations. The present study aimed at investigating the cytotoxic potential of the methanolic extract of this plant against brine shrimp larvae and human carcinoma cells at normoxic conditions. MATERIALS AND METHODS The in vivo lethality test was evaluated at various doses against brine shrimp larva...

In antimalarial research there are no standard procedures to determine the toxicity of a drug candidate. Among alternatives available, in vitro cytotoxicity assays most widely used predict toxic effects future therapeutic products. They have advantage over vivo assays, that they offer possibility restrain number experimental variables. The objective present study was compare cytotoxic methods b...

Euphorbiaceae is a family of plant spread in all parts of the world except very cold regions. The genus Euphorbia consists of over eighty-two species grown wildly in Iran. Some of Euphorbia species are used in the treatment cancer and tumors in different countries. The genus Euphorbia has been the source of a large number of biological active compounds. In this study petroleum ether, ether, eth...
