Cellular Membrane Protection Against Reactive Oxygen Species by Terminalia Arjuna and Its Active Component Baicalein

Oxidative stress and protection against reactive oxygen species in the pre-implantation embryo and its surroundings.

Oxidative stress is involved in the aetiology of defective embryo development. Reactive oxygen species (ROS) may originate from embryo metabolism and/or embryo surroundings. Embryo metabolism generates ROS via several enzymatic mechanisms. The relative contribution of each source seems different depending on the species, the stage of development, and the culture conditions. Several exogenous fa...

O 22: Reactive Oxygen Species and Epilepsy

Seizure activity has been proposed to result in the generation of reactive oxygen species (ROS), which then contribute to seizure-induced neuronal damage and eventually cell death. Although the mechanisms of seizure-induced ROS generation are unclear, mitochondria and cellular calcium overload have been proposed to have a crucial role. We aim to determine the sources of seizure-induced ROS and ...

Terminalia Arjuna: Its Chemistry, Pharmacology and Therapeutic Action

RADIOPROTECTIVE AND ANTIOXIDANT PROPERTIES OF INDIAN MEDICINAL PLANT, Terminalia arjuna

Using rat liver mitochondria as model systems, we examined the radioprotective and antioxidant effects of the Indian medicinal plant Terminalia arjuna. Various sohxlet fractions of the bark and the medicinal formulation arjunsal besides an active ingredient, baicalein, were examined for their ability to protect both rat liver mitochondria and cardiac homogenate against radiation and oxidative s...

Baicalein, an active component of Scutellaria baicalensis Georgi, prevents lysophosphatidylcholine-induced cardiac injury by reducing reactive oxygen species production, calcium overload and apoptosis via MAPK pathways

BACKGROUND Lysophosphatidylcholine (lysoPC), a metabolite from membrane phospholipids, accumulates in the ischemic myocardium and plays an important role in the development of myocardial dysfunction ventricular arrhythmia. In this study, we investigated if baicalein, a major component of Huang Qui, can protect against lysoPC-induced cytotoxicity in rat H9c2 embryonic cardiomyocytes. METHODS C...
