Preliminary Report on the Effect of Savanna Plants , and against Eggs and Immature Stages of Trichostrongylid Nematodes In Vitro.

The current study evaluated the anthelmintic effect of different extracts of , and on trichostrongylid eggs and infective larvae and determined the potential active components of each plant. Dried and macerated plant material was concentrated using rotaevaporation to obtain the crude extract (CE), followed by solvent partitioning to obtain hexanic (HexE), acetatic (AcE), and butanolic (BuE) extracts used for phytochemical analysis and anthelmintic efficacy testing in vitro. All the crude and partitioned extracts tested showed inhibition activity in the hatching of trichostrongylid eggs.

Ergot Alkaloids at Doses Close to EU Regulatory Limits Induce Alterations of the Liver and Intestine.

An increase in the occurrence of ergot alkaloids (EAs) contamination has been observed in North America and Europe in recent years. These toxins are well known for their effects on the circulatory and nervous systems. The aim of this study was to investigate the effect of EAs on the liver and on the intestine using the pig both as a target species and as a non-rodent model for human.

Cardiotoxicity of Senna occidentalis in sheep (Ovis aries).

The cardiotoxicity of Coffee senna (Senna occidentalis) was investigated in sheep that were fed diets containing its seeds, which are recognized as the most poisonous part of such weed. Dianthrone, the main toxic component of S. occidentalis, is known to impair mitochondrial oxidative phosphorylation, leading to myofiber degeneration.

Intoxication by Cyanide in Pregnant Sows: Prenatal and Postnatal Evaluation.

Cyanide is a ubiquitous chemical in the environment and has been associated with many intoxication episodes; however, little is known about its potentially toxic effects on development. The aim of this study was to evaluate the effects of maternal exposure to potassium cyanide (KCN) during pregnancy on both sows and their offspring. Twenty-four pregnant sows were allocated into four groups that orally received different doses of KCN (0.

Embryotoxic effects of Solanum lycocarpum St. Hill fruits consumption during preimplantation and organogenesis in rats.

Solanum lycocarpum St. Hill is a common plant in the Brazilian savanna. This plant has an alkaloid with stereospecific configuration to the synthesis of steroid hormones.
