This study was undertaken to investigate the potential toxicity and establish the no observed adverse effect level (NOAEL) and target organ(s) of negatively charged colloidal silica particles of different sizes, ie, SiO2 (EN20(-)) (20 nm) or SiO2 (EN100(-)) 2(100 nm), administered by gavage in Sprague-Dawley rats. After verification of the physicochemical(More)
The etiologic role of thrombotic and fibrinolytic disorders in Perthes' disease has not been determined. A case control study was conducted to determine whether thrombotic and fibrinolytic disorders are associated with Perthes' disease. Twenty-six patients with Perthes' disease were matched with 26 control patients for gender, age (2-year range), and time(More)
PURPOSE The study reported here was conducted to determine the systemic oral toxicity and to find the no-observed-adverse-effect level of 20 nm positively charged zinc oxide (ZnO(SM20(+))) nanoparticles in Sprague Dawley rats for 90 days. METHODS For the 90-day toxicity study, the high dose was set as 500 mg per kg of body weight (mg/kg) and the middle(More)
