The experimental toxicological findings of tramadol are reviewed and discussed. Tramadol is a centrally acting analgesic. In acute toxicity studies, LD50 values are estimated to be around 300-350 mg/kg body weight (rat, mouse, oral administration). After intravenous administration the LD50 values ranged from 50 to 100 mg/kg body weight. In subacute and chronic toxicity studies, clinical signs o...

OBJECTIVE To evaluate the effectiveness of constraint-induced movement therapy (CIMT) and combined mirror therapy for inpatient rehabilitation of the patients with subacute stroke. METHODS Twenty-six patients with subacute stroke were enrolled and randomly divided into three groups: CIMT combined with mirror therapy group, CIMT only group, and control group. Two weeks of CIMT for 6 hours a da...

Silver salts and nanosilver (NS) are the common antimicrobial used in the treatment of chronic wounds, so they are important to assess their dermal toxicity. Therefore, in this study, the possible dermal toxicity of NS particles and silver nitrate (AgNO3), was tested by determining the serum level of transforming growth factor-β1(TGF-β1) and study on of mouse skin tissue. In this stu...

Objective(s): Nanosilver is one of the most widely used nanomaterials due to its strong antimicrobial activity. Thus, because of increasing potential for exposure of human to nanosilver, there is an increasing concern about possible side effects of these nanoparticles. In this study, we tested the potential dermal toxicity of nanosilver bandage on serum chemical biomarkers in mice.  Materials a...

In the previous study, we have found that the cordycepin which was extracted from Cordyceps mycelia produced by growing Cordyceps militaris on the dead larva of Bombyx mori silkworms showed the anti-proliferative effect toward lung cancer cells without toxicity to non-cancer cells. In this work, the cordycepin was tested for its in vitro mutagenicity and in vivo toxicity. From the Ames test and...
