Objectives: The current preclinical study aimed at appraising the claim of anti diarrheal activity, acute and sub chronic oral toxicity of the polyherbal formulation Entoban to acknowledge its safety and efficacy. Methods: In order to investigate the antidiarrheal activity albino mice were treated with Entoban at doses of 2.5, 5, 10 mg/kg. For evaluation of acute toxicity the animals were treat...

according to the increased probability of the presence of nanomaterials in the aquatic ecosystems, the present study examined the toxicity of three engineered silver nanoparticles (agnps) as well as silver ions in the pontogammarus maeoticus, a brackish water benthic organism living in the littoral zone of the caspian sea. the animals were acutely exposed to different concentrations of two comm...

at first, in order to define acute toxicity of diazinon insecticide and butachlor herbicide, acute toxicity tests (lc5096h) were done, based on standard method (1989) o.e.c.d. in static way and for 96 hours. and the amount of acute toxicity (lc5096h) of diazinon and butachlor in 1 to 2 gram vimba vimba persa fry larva was determined to be 0.09 and 0.61 respectively. in order to do histology stu...

Introduction: Stress is a main factor influencing brain functions as revealed by the electroencephalogram (EEG) recordings. Moreover, different stress durations seemingly cause perturbations in brain waves and lead to mental disorders. This study investigates the effects of acute, sub-chronic and chronic stress on EEG in rats.  Methods: Twenty-eight Wistar adult male rats were randomly all...

The acute and sub-acute toxicity of safranal were studied in rat and mice within 2 and 21 days after exposure, respectively. For subacute toxicity, changes in weight as well as biochemical, hematological and pathological parameters were studied. The intraperitoneal LD50 values of safranal were 1.48 mL/kg in male mice, 1.88 mL/kg in female mice and 1.50 mL/kg in male rats. Oral LD50 values were ...
