Monascus Color Y-001, a natural food pigment produced from purpureus Y-001 fermentation, was administered orally by gavage to 4 Beagle dogs/sex/group for 90 days at doses of 0 (vehicle: 0.1% Tween 80, 10 mL/kg bw), 1, 5 and 25 mg/kg bw/day. In the clinical observations, vomiting/vomitus (dark red watery substance or undigested feed) observed males females in 25, but not 1 bw/day group relativel...

3.1. SCOPE AND LIMITATIONS The acute, subchronic, and chronic toxicology of the chlorinated dioxins, dibenzofurans, biphenyls, and related compounds have been reviewed extensively in recent years. This chapter summarizes knowledge on the toxicology of tetrachlorodibenzo-p-dioxin (TCDD), but also includes references to other dioxin-like compounds when relevant data are available. Included are se...

This research is to evaluate the acute and subchronic toxicities of “Kien ty chi thong - HV” granules through oral administration in experimental animals. The toxicity was determined by Litchfield Wilcoxon method Swiss mice. evaluated WHO OECD’s recommendation Wistar rats with doses 1.8 g/kg/day (equal recommended human dose) 5.4 (3 times as high 4 consecutive weeks. As a result, at highest dos...

Metal oxide nanoparticles, such as copper oxide (CuO), are mass produced for use in a variety of products like coatings and ceramics. Acute exposure to CuO nanoparticles has caused toxicity to many aquatic organisms, yet there is no information on the effect of prolonged CuO nanomaterial exposures. This study examined effects of chronic exposure to CuO nanoparticles on Xenopus laevis growth and...

Introduction. Occupational air is contaminated with zinc oxide nanoparticles in the copper smelting industry, especially of brass and copper. A wide range toxic effects varied clinical symptomatology observed its compounds. Competitive relations many other metals, including calcium, copper, iron, are foundation most cases intoxication. Long-term administration or compounds to laboratory rodents...

Food and drug control authorities in each country have issued warnings about the toxic effect potential of using commonly consumed traditional medicines. The safety assurance, standardization, market regulation herbal medicines being sold need to be determined. This study's goal is investigate acute subchronic toxicity cold-processed snakehead fish (Channa striata) flesh. In-vivo rats models we...

The large consumption of biodegradable films from cassava starch acetate (FCSA) as ingredients in food and pharmaceutical products requires the assessment of the possible toxicity of these products. The aim of this study was to investigate the toxicity of biodegradable film from cassava starch acetate after oral exposure of Wistar rats for 90 days. The amount of food consumed and the body weigh...

Acute and Subchronic Inhalation Toxicity of Chloroform in Rats and Mice: Tatsuya KASAI, et al. Japan Bioassay Research Center—In order to better characterize acute and subchronic toxicities of chloroform and to provide its basic toxicity data for risk assessment of humans exposed to chloroform in work and living environments, mice and rats of both sexes were exposed by inhalation to chloroform ...
