The use of this material under current use conditions is supported by the existing information. This material was evaluated for genotoxicity, repeated dose toxicity, developmental toxicity, reproductive toxicity, local respiratory toxicity, phototoxicity, skin sensitization potential, as well as, environmental safety. Repeated dose toxicity was determined using to have the most conservative sys...
A programme of studies was conducted to establish the safety of a xylanase expressed in a self-cloned strain of Bacillus subtilis to be used as a processing aid in the baking industry. To assess acute and subchronic oral toxicity, rat feeding studies were conducted. In addition, the potential of the enzyme to cause mutagenicity and chromosomal aberrations was assessed in microbial and tissue cu...
Teucrium Polium L. (TP) is widely used in traditional medicine of many countries including Iran. There are various reports about pharmacological properties of TP such as calcium antagonist, anti- ulcer, anti – diabetic. There are a few reports about possible toxicological effects of this plant. In the present study we designed to evaluate the subchronic toxicity of Teucrium Polium total extract...

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...
Background and objectives: Salvia chloroleuca Rech. f. & Allen., is an endemic species growing wildly in north east and center parts of Iran but there is no information about its safety. To provide information about the safety of the species, we evaluated its acute and sub chronic toxicity in rats. Methods: In acute toxicity study, the aqueous methanol (80%) extract at a single dose of...
Aromatic extracts (AEs; distillate AEs [DAEs] and residual AEs [RAEs]) are complex, highly viscous liquid petroleum streams with variable compositions derived by extraction of aromatic compounds from distillate and residual petroleum fractions from a vacuum distillation tower, respectively. The DAEs generally contain significant amounts of polycyclic aromatic compounds (PACs) and are carcinogen...
The search for new and safe drugs has led to a purposeful synthesis of coordination compounds metals with bioligands based on - hermacite (magnesium bis (citrate) germanate), gercocyte germanate). aim the study was investigate morphological changes in liver rats after administration (Mg, Co) germanates subacute subchronic experiment. Materials methods research. experiment performed mature male ...
