Uvaria chamae is used in the treatment of sickle cell crisis Benin. The aim this work to determine safety roots aqueous extract wistar rats. was obtained by maceration. tests for Acute Oral Toxicity (AOT) and Sub-Chronic (SCT) respectively forced gavage a single dose 2000 mg / Kg 200 body weight 28 days were performed on female Wistar animals, serum creatinine, transaminases number white blood ...

ABSTRACT Introduction: Impaired wound healing is a major concern specially in diabetic patients due to unregulated chronic hyperglycemia which further may lead to ulcer, gangrene, and its complications, therefore the development of natural, nontoxic and effective agent is required. we carried out an acute and subacute oral toxicity study on the Cyperus Papyrus (CP) ash in Wistar albino rats. C...

The aim of the study was to compare the acute toxicity of diclofenac to juvenile and embryonic stages of the zebrafish (Danio rerio). Acute toxicity tests were performed on the aquarium fish Danio rerio, which is one of the model organisms most commonly used in toxicity testing. The tests were performed using a semi-static method according to OECD guideline No. 203 (Fish, acute toxicity test). ...

There is the need to integrate existing toxicity data in a coherent framework for extending their domain of applicability as well as their extrapolation potential. This integration would also reduce time and cost-consuming aspects of these tests and reduce animal usage. In this work, based on data extracted from literature, we have assessed the advantages that a dynamic biology-toxicant fate co...

The authors present a method to predict fish survival under exposure to fluctuating concentrations and repeated pulses of a chemical stressor. The method is based on toxicokinetic-toxicodynamic modeling using the general unified threshold model of survival (GUTS) and calibrated using raw data from standard fish acute toxicity tests. The model was validated by predicting fry survival in a fish e...

Sediment toxicity tests are valuable tools for assessing the potential effects of contaminated sediments in dredged material evaluations because they inherently address complexity (e.g., unknown contaminants, mixtures, bioavailability). Although there is a need to understand the chronic and sublethal impacts of contaminants, it is common to conduct only short-term lethality tests in evaluations...

Fish acute toxicity studies are required for environmental hazard and risk assessment of chemicals by national and international legislations such as REACH, the regulations of plant protection products and biocidal products, or the GHS (globally harmonised system) for classification and labelling of chemicals. Alternative methods like QSARs (quantitative structure-activity relationships) can re...
