An Organic Fraction of L'Her Ex. Aiton Prevents Neuroinflammation in a Rat Ischemic Model.

Background: L'Her Ex. Aiton, presenting antioxidant and anti-inflammatory activities, is traditionally used to treat bruises and headaches and as a healing agent. This study aimed to investigate whether its organic fraction (EAOr) has neuroprotective properties against neuroinflammation in the context of ischemia/reperfusion.

[Increased vascular density with indirect myocardial revascularization in normal rat hearts].

Background: The aim of this study was to identify if the interaction of myocardial revascularization methods increases the functional vascular area.

Methods: A 4x3 factorial design was performed in 11 groups, five rats per group, ten samples per rat, evaluated at 45 days postoperative, with different surgical combinations. The magnitude of the interaction was evaluated by immunoexpression of vascular endothelium-derived growth factor, fibroblast growth factor and tyrosine receptor, to allow the activity of vascular endothelium-derived growth factor, fibroblast growth factor and thrombin (Flk-1), as well as vascular area measurement; Both measures were performed by computerized morphometry.

[Ovarian denervation and polycystic ovary].

Background: Ovarian inervation is limited to the superior pedicle and ovarian artery to loose itself within the gonadal smooth muscle. Hence, it is far from clear how is it that the ovary preserves its communication with hypothalamic and pituitary structures for feedback regulation. There is a lack of precision concerning structures and mechanisms involved in the genesis of polycystic disease.
