The aim of the present study was to elucidate consistent patterns in chronic polycyclic aromatic compound (PAC) toxicity to soil and sediment inhabiting invertebrates. Therefore we examined our experimental dataset, consisting of twenty-one chronic effect concentrations for two soil invertebrates (Folsomia candida and Enchytraeus cripticus) and two sediment invertebrates (Lumbriculus variegatus...
The development of rapid methods for determining chronic toxicity parameters of chemical compounds introduced by the oral route into an organism with water was studied. Formulas are verified with which threshold values and no-effect toxicity doses for substances can be obtained on the basis of various toxicologic parameters. For the example of organophosphates, a methodological scheme was devel...
Background and Aim: HESA-A is a marine biological compound that was recently patented in the Islamic Republic of Iran, revealed anti-tumor properties in-vitro and in-vivo. The objective of this study was to investigate the acute, sub-acute, and chronic toxicity of HESA-A in mice and rats. Materials and Methods: The acute toxicity testing of HESA-A (0.5-18 g/kg) orally in different groups of mi...
chronic plaque-type psoriasis may be difficult to control without the use of potent systemic therapies that are accompanied by systemic toxicity. mycophenolate mofetil is a novel agent that may be effective in the treatment of chronic plaque type psoriasis. our purpose was to investigate of the safety and efficacy of oral mycophenolate mofetil in the treatment of chronic plaque-type psoriasis. ...
