objective(s):copper oxidenanoparticles have different industrial applications so it is inevitable that nanoparticulate products finally find their way into aquatic ecosystems. nevertheless there is little information available about their effects on some of edible fish. the present study aims to determine the acute toxicity and evaluate the effect of two sub-acute concentrations (50 and 70% 96 ...

We tested the effects of the aqueous extract of Petiveria alliacea leaves on acute and sub-chronic toxicity, hematocrit and blood glucose level and intestinal motility of male albino NGP mice of 20 to 25 g mean weight. Treatments were in all cases doses of 1,000 and 2,000 mg/kg animal weight and a control treatment with 0.5 ml distilled water, using 10 animals per treatment and administered ora...

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...

Lactulose has profound health benefits by way of increasing bifidobacterial flora in the intestine of infants thereby protecting them against enteric infection, constipation and systemic encephalopathy. In the present study to assess the sub chronic toxicity of lactulose syrup, the rats were fed on a basal feed supplemented with lactulose syrup at 0.5, 1.0, 2.0 and 5.0% for a period of 21 weeks...

Alfa-cypermethrin (α-CP) a synthetic pyrethroid (type-II) insecticide, dissolved in dimethyl sulfoxide (DMSO-1 mL) was given consecutive daily orally for 60 days at 1/10 LD50 (14.5 mg/kg). The animals were sacrificed on day 61. Biochemicals, cytochrome P450, b5 contents in liver along with antioxidant status, tissue residual concentration, and brain GABA level were studied. It increased the ser...

ETHNOPHARMACOLOGICAL RELEVANCE Hericium erinaceus is a culinary-medicinal mushroom and has a long history of usage in traditional Chinese medicine as a tonic for stomach disorders, ulcers and gastrointestinal ailments. AIM OF THE STUDY The present investigation was aimed to evaluate the potential toxic effects of the aqueous extract from the fruiting bodies of H. erinaceus in rats by a sub-ch...

2,4,6-Trichlorophenol (2,4,6-TCP) is a common chemical intermediate and a by-product of water chlorination and combustion processes, and is a priority pollutant of the aquatic environment in many countries. Although information on the toxicity of 2,4,6-TCP is available, there is a lack of information on the predicted no-effect concentration (PNEC) of 2,4,6-TCP, mainly due to the shortage of chr...
