Role of vasoactive mediators in the pathogenesis of Chagas' disease.

چکیده
This review focuses on the vascular pathogenesis of Chagas' disease, the cardiomyopathy caused by infection with the parasitic protozoa Trypanosoma cruzi. Recent studies strongly suggests that T. cruzi infection is linked to functional changes in the activity of two potent vasoactive peptidergic mediators, endothelin-1, a vasoconstrictor, and kinins, a group of vasodilator and pro-inflammatory peptides related to bradykinin. Understanding the molecular mechanisms underlying disturbances of vascular homoeostasis? induced by T. cruzi may provide opportunities for therapeutic intervention and amelioration of heart pathology.

متن کاملI-31: Antihistamine & Ovarian Hyperstimulation syndrome
Background: Ovarian hyperstimulation syndrome (OHSS) is a rare iatrogenic complication of ovulation stimulation. The pathogenesis of OHSS is uncertain. The crucial event appears to be an increase in capillary permeability by vasoactive mediators such as cytokine and histamine. The aim of this study is to evaluate the role of loratadine (antihistamine) in preventing ovarian hyperstimulation synd...

Objective(s):Therapies with high levels of oxygen are commonly used in the management of critical care. However, prolonged exposure to hyperoxia can cause acute lung injury. Although oxidative stress and inflammation are purported to play an important role in the pathogenesis of acute lung injury, the exact mechanisms are still less known in the hyperoxic acute lung injury (HALI). Materials ...
