The antidepressant-like effects of N-palmitoylethanolamide (PEA), a putative endocannabinoid, was investigated in mice using the tail suspension test (TST) and the forced swimming test (FST). In TST, PEA (10, 20, and 40 mg/kg) produced a statistically significant reduction in immobility (50, 32, and 34%, respectively, vs. the control group), whereas fluoxetine (20 mg/kg) reduced immobility by 3...
OBJECTIVE The aim of the study to elicit effects of pure quercetin in pentylenetetrazole (PTZ) and picrotoxin induced seizures. MATERIALS AND METHODS Each animal group was divided into six groups and composed of six rats. Rats were assigned to the following experiments and groups (G): (G1) PTZ 45 mg/kg + DMSO; (G2) PTZ 45 mg/kg + 5 mg/kg quercetin; (G3) PTZ 45 mg/kg + 10 mg/kg quercetin; (G4)...
Among 117 of the albino mice used in this study, 108 were intraperitionally infected with 100 X 106 promastigotes of Leishmania donovani (MHOM\ IQ\ 982\ BRCI) strain, while the rest groups (9) were left without infection. The inoculation of albino mice caused the elevation of liver and spleen weight after 7-15 days and the treated mice with 20 mg/kg by Pentostam and Allupurinol for 10 and 15 da...
quantum dots are new types of fluorescent materials for biological labeling. as a result, qds toxicity study is an essential requirement for future clinical applications. therefore, the cytotoxic cdse:zns quantum dots effects on some organs in mice are presented in this study. in this work, 10, 20 and 40 mg/kg doses of cdse:zns quantum dots were injected to 32 adult male mice. structural and op...
Agmatine [2-(4-aminobutyl)guanidine], is a novel endogenous ligand at alpha2-adrenoceptors, imidazoline and N-methyl-D-asparate receptors, as well as a nitric oxide synthase inhibitor. The present study tested whether agmatine (5-40 mg/kg, sc) modulated the locomotor, sensitizing, and discriminative stimulus effects of nicotine in male Wistar rats. Agmatine (10-40 mg/kg) affected neither the ba...
N(G)-nitro-D-arginine methyl ester (D-NAME), considered as an inactive enantiomer of NAME, is generally used as a negative control for NO synthase inhibition with L-NAME. The aim of this work was to compare the effect of L-NAME (20 and 40 mg/kg/day), and D-NAME (40 mg/kg/day) on hemodynamic and structural parameters in the rat cardiovascular system. After 4 weeks of treatment, blood pressure an...
OBJECTIVE Dependence and tolerance are major restricting factors in the clinical use of opioid analgesics. In the present study, the effects of thymoquinone, the major constituent of Nigella sativa seeds, on morphine dependence and tolerance were investigated in mice. MATERIALS AND METHODS Male adult NMRI mice were made tolerant and dependent by repeated injections of morphine (50, 50, and 75...
