title: Protective effect of Aloe vera on polymicrobial sepsis in mice.
abstract: Sepsis is an acute life-threatening clinical condition and remains the major cause of death in intensive care units. The primary pathophysiologic event central to the septic response is an overwhelming activation of the inflammatory system and countervailing response from the anti-inflammatory system. However, the cause of this perturbation has yet to be elucidated. In this study, we report that Aloe vera therapeutically reverses the lethality induced by cecal ligation and puncture (CLP), a clinically relevant model of sepsis. The administration of Aloe vera ameliorated the multiple organ dysfunction syndrome, as evidenced by the serum levels of biochemical parameters and histological changes. In order to investigate the pharmacological mechanism of Aloe vera, the levels of the cytokines, tumor necrosis factor (TNF)-alpha, interleukin (IL)-1beta, and IL-6 were determined by ELISA at various time points. The increases in the levels of TNF-alpha, IL-1beta, and IL-6 were attenuated by Aloe vera.In vivo administration of Aloe vera also markedly enhanced bacterial clearance. Our findings suggest that Aloe vera could be a potential therapeutic agent for the clinical treatment of sepsis.
