Subchronic oral toxicity of silver nanoparticles

Subchronic inhalation toxicity of silver nanoparticles.

The subchronic inhalation toxicity of silver nanoparticles was studied in Sprague-Dawley rats. Eight-week-old rats, weighing approximately 253.2 g (males) and 162.6 g (females), were divided into four groups (10 rats in each group): fresh-air control, low dose (0.6 x 10(6) particle/cm(3), 49 microg/m(3)), middle dose (1.4 x 10(6) particle/cm(3), 133 microg/m(3)), and high dose (3.0 x 10(6) part...

determination of absorbed silver nanoparticles and histopathologic abnormalities in kidney tissue: a subchronic dermal toxicity

Toxicity of silver nanoparticles on virus

This study investigated the antiviral effect of silver nanoparticles on MS2 bacteriophage. Silver nanoparticles were synthesized via chemical reduction method and characterized by transmission electron microscope. Synthesized silver nanoparticles and cultivated MS2 bacteriophage were characterized using zetasizer. The result in this study indicates that the toxicity of silver nanoparticles on M...

Aquatic Toxicity Comparison of Silver Nanoparticles and Silver Nanowires

To better understand the potential ecotoxicological impact of silver nanoparticles (AgNPs) and silver nanowires (AgNWs) released into freshwater environments, the toxicities of these nanomaterials were assessed and compared using Organization for Economic Cooperation and Development (OECD) test guidelines, including a "Daphnia sp., acute immobilization test," "Fish, acute toxicity test," and "f...

Thirteen-Week Study of PM014 Subchronic Oral Toxicity in Rats

PM014 is a modified herbal formula based on Chung-Sang-Bo-Ha-Tang, which is a well-known prescription drug used for curing various inflammatory pulmonary diseases. We previously showed that PM014 attenuated lung inflammation in a murine model of chronic obstructive pulmonary disease (COPD). The objective of the present study was to evaluate the chronic oral toxicity of PM014 in rats. PM014 was ...
