Anxiety and disorders associated with anxiety are increasing rapidly throughout the world. In the present research Arnica montana (Asteraceae) was studied on neuro-pharmacological and analgesic effect in mice. Decreased locomotor and exploratory activities (open field, head dip cage, stationary rod, cage cross, forced swimming and light and dark) were observed in mice at the dose of 100 mg/kg. ...
The effects of pretransplant conditioning with high-dose busulfan, a myeloablative but nonimmunosuppressive alkylating agent, on reconstitution of lymphoid tissues by donor cells after bone marrow transplantation (BMT) has not been extensively examined. We used flow cytometric analyses to study the kinetics and extent of lymphocyte repopulation in C57BL/6 mice (immunophenotype Ly-5.2) given gra...
background: cylophosphamide is used alone or in combination with other drugs for treatment of neoplastic diseases. hemorrhagic cystitis is a major potential toxicity and dose limiting side effect of cyclophosphamide. the aim of this study was to evaluate the effects of lycopene compared with some antioxidants for the prevention of cyclophosphamide induced hemorrhagic cystitis in rats. methods...
Etoricoxib features antioxidant and anti-inflammatory properties concomitantly, suggesting that it may be beneficial in testicular ischemia reperfusion (I/R) damage. Our aim is to investigate the effects of etoricoxib on testicular I/R damage induced with torsion-detorsion (TD). The etoricoxib + torsion-detorsion (ETD) groups of animals were given etoricoxib in 50 and 100 mg/kg of body weight (...
In this study, the 4-week oral toxicity and anti-cancer activity of the hexane layer of Melia azedarach L. var. japonica Makino's bark extract were investigated. We carried out a hollow fiber (HF) assay and 28- day repeated toxicity study to confirm the anti-cancer effect and safety of the hexane layer. The HF assay was carried out using an A549 human adenocarcinoma cell via intraperitoneal (IP...
Cethromycin is a ketolide with in vitro activity against macrolide-sensitive and -resistant strains of Streptococcus pneumoniae. We compared its in vivo efficacy to erythromycin in a mouse model of acute pneumonia induced by two virulent clinical strains: a serotype 3 susceptible strain (P-4241) (MICs: erythromycin, 0.03 microg/ml; cethromycin, 0.015 microg/ml) and a serotype 1 strain resistant...
Background and Aim: Polycystic ovary syndrome (PCOS) is a complex endocrine and metabolic disorder, which is characterized by ovulatory dysfunction and hyperandrogenism. Regarding to the antioxidant properties of green tea (Camellia sinensis) compounds, the present study was done to evaluate the effect of aqueous extract of green tea and catechin on the status of sex hormones and ovaries in pol...
The efficacy of a new class of drugs for Pneumocystis carinii pneumonitis was demonstrated. 566C80, a hydroxynaphthoquinone, administered orally in a dose of greater than or equal to 100 mg/kg of body weight per day prophylactically prevented P. carinii pneumonitis in 90% or more of rats, while all untreated control animals developed pneumonitis. When 566C80 (100 mg/kg per day) was administered...
Metformin lowers blood pressure in humans and in experimental animal models. To determine the mechanism of acute metformin-induced hypotension, we measured changes in mean arterial pressure (MAP) and heart rate (HR) during metformin alone (0, 10, 50, 100 mg/kg i.v.; n = 10) and during concomitant alpha adrenergic (phentolamine, 5 mg/kg; n = 5), beta adrenergic (propranolol, 3 mg/kg; n = 6), mus...
1. The comparative protective abilities of a grape seed proanthocyanidin extract (GSPE) (25-100 mg/kg), vitamin C (100 mg/kg), vitamin E succinate (VES) (100 mg/kg) and beta-carotene (50 mg/kg) on 12-O-tetradecanoylphorbol-13-acetate (TPA)-induced lipid peroxidation and DNA fragmentation in the hepatic and brain tissues, as well as production of reactive oxygen species by peritoneal macrophages...
