Efeito do extrato hidroalcóolico de Cassia angustifolia na gestação de camundongos

Abstract

Cassia angustifolia (Senne), is usually associated with its effects on the gastrointestinal tract where besides being used as purgative. The popular culture associated this plant with abortion and emmenagogue effects. Mostplants used as emmenagogu eare the same used as abortion, there is no clear distinction between the two intentions. Plants traditionally used to induce abortion are administered in excessively high doses, which can cause toxic effects to the woman's body. The main chemical constituents of Cassia angustifolia are diantronas-8-8'-called diglicosídeos senossides AF, with a predominance of A senossides. This components can inducing uterine contractions, increase blood flow to the uterus and its appendages, increasing the risk offetal loss, disruption of the mitochondrial oxidative phosphorylation. Trophoblast giant cells (TGC) present in maternal interface - fetal, are of great relevance to the balance between the fetus and mother. There are also uterine Natural Killer cells (UNK) whose main function is the release of cytokines such as IFN-? which leads to dilation of the decidual spiral arteries and maintenance of decidual integrity, contributing thus to the normal development of the decidua and placental. In this context, the present study evaluated the possible effects of administration of the hydroalcoholic extract of Cassia angustifolia (Senna) in different periods of pregnancy in mice, both in the mother and the fetus, as well as behavioral effects and the effects on cells and TGCs and UNK by morphological, cytochemical and stereological studying. There was also thechromatographic profilein order to as certain the chemical constituents of the extract. We found that theTGCs are locatedin the midst of blood infiltration, or even around an early necrosis, thereby exerting a role phagocytic activity against the inflammatory and tissue remodeling. UNK cells showed a significant increase in endometrial farthest region of the embryo. Furthermore, the treatment showed behavioral changes in females treated with the corresponding extract.The morphological and histological analysis showeda important prejudicial effect of senne extract in mouse pregnancy and after phytochemical analysis we can supposed that this effects was caused probably by the A and B healthy senossídeos (anthraquinone derivatives) the main constituents of Senne extract. The results support an important risk of the indiscriminate use of Senneforpregnant woman
