Silver nanoparticles (AgNPs), owing to their unique physical and chemical properties, have become increasingly popular in consumer products. However, data on their potential biological effects on marine organisms, especially invertebrates, remain very limited. This proof of principle study reports the chronic sub-lethal toxicity of two coated AgNPs (oleic acid coated AgNPs and polyvinylpyrrolid...

All aquatic organisms are directly or indirectly affected by the physical characteristics of their environment, especially the chemical composition of the water. The high concentration levels, damage tissues and interfere with the normal growth and proliferation. The aim of this research was to Investigation acute toxicity of ZnSO4 and CuCl2 to Gambusia holbrooki ...

Objective: The present investigation was carried out to evaluate the safety of an aqueous extract of the seeds of Calycotome villosa (Poiret) Link (subsp. intermedia) by determining its cytotoxicity and potential toxicity after acute and sub-chronic administration in rodents. Materials and Methods: Cytotoxic activity was tested in cancer and non-cancer cell lines HeLa, Mel-5, HL-60 and 3T3. Acu...

background and objectives: salvia chloroleuca rech. f. & allen., is an endemic species growing wildly in north east and center parts of iran but there is no information about its safety. to provide information about the safety of the species, we evaluated its acute and sub chronic toxicity in rats. methods: in acute toxicity study, the aqueous methanol (80%) extract at a single dose of 2000...

Coriandrum sativum L. (CS) seeds are known to possess therapeutic potentials against a variety of physiological disorders. This study assesses acute and sub-chronic toxicity profile of hydro-methanolic extract of CS seeds using OECD guidelines. In acute toxicity study, mice were once orally administered 1000, 3000 and 5000 mg/kg body weight of CS extract. There were no any behavioral alteration...

Article history: Received on: 28/02/2014 Revised on: 02/04/2014 Accepted on: 22/04/2014 Available online: 28/04/2014 Acute and sub-chronic toxicity studies of the aqueous extract of the root bark of C. sieberiana (Caesalpiniaceae), a plant used locally in Ghana for the treatment of pain, was carried out in rodents. In the acute study, a single oral dose (5000 mg/kg) of the aqueous extract of C....

Silver nanoparticles (Ag NPs) have been widely used as new potent antimicrobial agents in cosmetic and hygienic products. Present study compares the tissue levels of Ag NPs in different organs of Guiana Pigs quantitatively after dermal application and analysis the morphological changes and pathological abnormalities on the basis of the Ag NPs tissue levels. Before toxicological assessments,the...

The freshwater fish, Channa gachua was exposed to sub-lethal concentrations of an organophosphorus pesticide, monocrotophos. The fish was exposed to acute toxicity of monocrotophos for 16, 24 and 48 hours while for chronic toxicity it was exposed for 15, 30 and 45 days. The monocrotophos was found to be toxic to the fish, which was found to be increasing with the increase of its concentration. ...
