Toxicity Evaluation of Essential oil of Trachyspermum ammi in Acute and Sub-chronic Toxicity Experiments
Background: Trachyspermum ammi is one of the prominent plant in traditional medicine of the east with several medicinal effects such as improvement of stomach disease, digestive disorder, diarrhea, hemorrhoid, bladder stones, respiratory disease and etc. Medicinal plants is one of the important reason of toxicity particularly in children and the elderly therefore, evaluation of the toxic effect...
متن کاملSub-Acute Oral Toxicity of Zinc Oxide Nanoparticles in Male Rats
ZnO-NPs suspended in distilled water were administered to Wistar rats at dose of 10 mg/ kg body weight through oral gavage for 5 consecutive days. The mean body weight gain in rats given ZnO-NPs was similar to this of control group, so no significant differences in the relative organs weight were observed between the ZnO-NPs treated-rats and control. Moreover, ZnO-NPs-exposed rats showed normal...
متن کاملDetermination of acute toxicity and the effects of sub-acute concentrations of CuO nanoparticles on blood parameters in Rutilus rutilus
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 ...
متن کاملEffects of sub-acute and sub-chronic inhalation of 1-bromopropane on neurogenesis in adult rats.
PURPOSE 1-Bromopropane (1-BP) intoxication is associated with depression and cognitive and memory deficits. The present study tested the hypothesis that 1-BP suppresses neurogenesis in the dentate gyrus, which is involved in higher cerebral function, in adult rats. METHODS Four groups of 12 male Wistar rats were exposed to 0, 400, 800, 1000 ppm 1-BP, 8 h/day for 7 days. Another four groups of...
متن کاملSub-Chronic Toxicity Study of Alpha-Cypermethrin in Rats
Alpha-cypermethrin (?-CP) a synthetic pyrethroid (type-II) insecticide, dissolved in dimethyl sulfoxide (DMSO-1ml) given consecutive daily orally for 60 days at 1/10LD50 (14.5mg/kg). The animals were sacrificed on day 61st. Biochemicals, cytochromeP450, b5 contents in liver along with antioxidant status, tissue residual concentration, and brain GABA level were studied. It increased the serum am...
