OBJECTIVE Previously, analgesic, hypnotic, and anticonvulsant effects have been suggested for Rosa damascena (R. damascena). In the present study, possible anti-seizure and neuro-protective effects of hydro-alcoholic extract of R. damascena has been investigated after inducing seizures in rats by pentylenetetrazole (PTZ). MATERIALS AND METHODS The rats were divided to five groups: (1) CONTROL...

Cryptosporidium parvum, Tyzzer, 1912 is identified as a common cause of diarrhoea in immunocompetent individuals. In immunocompromised, especially HIV-infected subjects, cryptosporidiosis causes severe chronic diarrhoea. In this study, nitazoxanide (NTZ) was compared for curative activity with sinefungin (SNF) and paromomycin (PRM) in immunosuppressed rats, a screening model for anticryptospori...

Research examining the memory-enhancing effects of glucose in humans has been limited to mnemonic tasks lacking affective components, even though glucose may be a mechanism for emotion-induced memory enhancement. This limitation does not permit analysis of interactions between the enhancing properties of emotional stimuli and glucose. Participants were administered either glucose or saccharin 1...

BACKGROUND Cryptococcal meningoencephalitis is a lethal infection with relatively few therapeutic options. The optimal dosage of liposomal amphotericin B (LAmB) alone or in combination with flucytosine is not known. METHODS A murine model of cryptococcal meningoencephalitis was used. The fungal density in the brain was determined using quantitative cultures. Pharmacokinetic-pharmacodynamic re...

The aim of this study was to evaluate the anti-nociceptive effects of a low, sub-effective dose of amitriptyline, in combination with the different doses of ethanolic and aqueous extracts of Crocus sativus following sciatic nerve chronic constriction injury (CCI) in rats. Amitriptyline (3, 10 and 30 mg/Kg, i.p.) and the extracts (25, 50 and 100 mg/Kg, i.p.), were separately administered at the ...

The effects of radiation and chemotherapy on gonadal function are relevant to the morbidity induced by such treatments. Cyclophosphamide given i.p. to rats on Day 30 of age delayed vaginal opening, prevented vaginal cyclicity, and caused a reduction in serum estradiol and progesterone. Antral follicular atresia increased in a dose-dependent fashion in response to cyclophosphamide (0 mg/kg, 53.5...

BACKGROUND Sleep disorders are accompanied by several complications, and currently used soporific drugs can induce unwanted effects such as psychomotor impairment, tolerance, amnesia, and rebound insomnia. OBJECTIVES The present study was carried out to investigate if Ocimum basilicum has a sleep-prolonging effect. MATERIALS AND METHODS This work was an experimental study on 72 mice which w...

background and aims: neurons are injured under physical, chemical and pathological conditions. the effect of peripheral nervous system injuries may return as retrograde to the cell body of neurons in central nervous system resulting in brain and spinal cord degeneration. because of high content of camphor and borneol, achillea biebersteinii from asteracea family may be effective in prevention t...
