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: ...

The aim of this study was to investigate the effects of Ginkgo biloba extract (EGb 761) on male copulatory behavior in rats. EGb 761 (1 mg/ml) induced significant production of testosterone (T) in rat Leydig cells in vitro. Its effects on sexual behavior were then tested in Long-Evans male rats after 7, 14, 21, or 28 days of oral gavage of vehicle (distilled water) or EGb 761 at doses of 10, 50...

Background: Yearly the Shanxi coal chemical industry extracts many coal resources, producing at the same time many polycyclic aromatic hydrocarbons (PAHs) that are emitted as by-products of coal incomplete combustion. Methods: Sixty-six soil samples collected from 0 to 100 cm vertical sections of three different agricultural (AS), roadside (RS) and park (PS) functional soils around a chemical p...

in vitro antioxidant and erythrocyte protecting activities by aqueous extract of ficus thonningii leaves on blood cells were studied in acetaminophen treated rats. the extract was safe at limit dose of 5000 mg kg-1body weight. the extract demonstrated dose dependent antihemolytic effect at dose levels between 50 and 200 mg kg-1 body weight. the lowest antihemolytic effect was observed at dose l...

Zincovit drop is a combined formulation of multivitamins-minerals, flax seed oil and lysine. This study has focused on the in vivo antioxidant potential of Zincovit drop against carbon tetrachloride induced oxidative stress in rats. Rats divided into six groups containing six rats in each group. Zincovit drop at the dose of 25 mg/kg/day, 50 mg/kg/day and 100 mg/kg/day was investigated in carbon...

Using microdialysis, we have examined the effects of ketamine on concentrations of total nitric oxide oxidation products (NOx-) in the rat hippocampus and striatum in vivo to investigate the relationship between anaesthesia and NOx- production in the brain. Ketamine 25, 50 and 100 mg kg-1 i.p. increased NOx- concentrations to mean 125 (SD 13)%, 165 (11)% and 193 (13)% of basal, respectively, in...

Parkinson's disease (PD) is a neurodegenerative disease characterized by the selective loss of dopamine (DA) neurons of the substantia nigra pars compacta (SNc). The events, which trigger and/or mediate the loss of nigral DA neurons, however, remain unclear. Neuroleptic-induced catalepsy has long been used as an animal model for screening drugs for Parkinsonism. Administration of haloperidol (1...

The present study aimed to examine the effect of the histone deacetylase inhibitor, vorinostat (SAHA), on renal function in a calcium oxalate crystal mouse model, and to investigate the mechanism underlying the renoprotective effect of SAHA. Calcium oxalate crystal formation was induced in 8 week‑old male C57BL/6 mice by administering 100 mg/kg glyoxylate for 7 days. A total of 24 male C57BL/6 ...

Undertaken study deals with any vulnerable changes by the radioprotective drug 2-mer captopropionylglycine, after administering in variable concentration (20, 50, 100, 200 and 500 mg/kg body weight) of the liver of adult mice at 1, 3, 7 and 14 days interval. The lower doses, 20 and 50 mg/kg body-weight of MPG did not affect the liver at all while at higher doses of 100, 200 and 500 mg/kg body-w...
