INTRODUCTION While the literature is replete with studies of the toxic potency of pentachlorophenol (PCP), site-specific criteria for native aquatic species that can be used in ecological risk assessments has been lacking and application of toxicity information for non-native species is controversial. MATERIALS AND METHODS In the present study, acute and chronic toxicities of PCP to six aquat...

Background: Ferula species have shown wide range of pharmacological properties but there is no study on oral safety profile of Ferula persica due to standard toxicology guidelines. Objective: This study aimed to evaluate the acute and subchronic oral toxicity of the alcoholic extract of the aerial parts of Ferula persica to provide its safe dose for long term oral administrations as a possible...

background: the assays currently available for the detection of specific anti- toxoplasma antibodies may vary in their abilities to detect serum immunoglobulins, due to the lack of a purified standardized antigen. the aim of this study was evaluation the recombinant toxoplasma gondii sag1 antigen for the serodiagnosis of acute and chronic toxoplasmosis. methods : this study describes an elisa u...

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 ...

Alpha-cypermethrin, a synthetic pyrethroid, is used as an insecticide in agricultural settings and is increasingly replacing organophosphates and carbamates because of lower application rates and lower toxicity to mammals. Because very little is known about the acute and chronic toxicity of this compound for soil-living organisms, the present study investigated acute and sublethal toxicity of a...
