Standard Toxicity Test

AbstractThe applicability of ionic liquids (ILs) has increased over the last years, and even new opportunities are becoming a reality, i.e. mixtures of pure IL and inorganic salt as electrolytes for smart electrochemical devices, yet the effects on the environment are almost unknown. In this work, the ecotoxicity of two pure protic ILs (Ethylammonium nitrate and Ethylimidazolium nitrate) and two pure aprotic ILs (butylmethylpyrrolidinium bis(trifluoromethylsulfonyl)imide and butyldimethylimidazolium bis(trifluoromethylsulfonyl)imide) and that of their binary mixtures with inorganic salts with common cation was tested towards changes in the bioluminescence of the bacteria Aliivibrio fischeri, using the Microtox® standard toxicity test. EC50 of these mixtures was determined over three standard periods of time and compared with the corresponding values to pure ILs. Results indicate that the aprotic ILs are more toxic than protic and that aromatic are more toxic than non-aromatic. The addition of inorganic mono (LiNO3), di (Ca(NO3)2·4H2O, Mg(NO3)2·6H2O) and trivalent (Al(NO3)3·9H2O) salts in binary mixtures with EAN was analysed first. The latter was found to induce an important increase in toxicity. Finally, mixtures of IL-inorganic lithium salt (LiNO3, for the protic ILs and LiTFSI for the aprotic ILs) toxicity was also studied, which showed toxicity levels strongly dependent on the IL of the mixture.

Areca (Areca catechu L.) seeds ethanolic extract (AE) exhibits antiproliferative activity and induces apoptosis on T47D and MCF-7 cells. This study aimed to verify AE safety using acute toxicity test to support its development as chemopreventive agent. Male Sprague Dawley Rat (Rattus norvegicus) age 8 weeks divided into five groups, one group of control treated with 0.5% CMC-Na only and four groups for treatment. Single dose in oral administration was done to test animal with various dose of AE starts from lowest dose to highest dose expected toxic to all of test animal (0.1; 0.72; 5.36 and 10 gram/kgBW). Observation was done during 24 hours and continued for 14 days. The observation criteria were toxic symptoms, appearance and mechanism of toxic effect and pathology of vital organ. Histopathology analysis of some vital organs was done with Haematoxyllin&Eosin (H&E) staining. Toxic effect did not appear either on treatment groups or control group. Treatment of single dose of areca ethanolic extract, even in highest dose, did not cause the death of the animals. Therefore, observation extended to 14 days and terminated by necroption of the animals. All of groups did not show histopathological alterations in microscopic observation. Category of the potential toxicity of AE is practically non-toxic, ie 10 g/kgBW. The result shows the safety of areca seed ethanolic extract which is important for its development as chemopreventive agent.Keywords: Areca catechu, acute toxicity, rat
