Green tea extract protects against tuberculosis

Summary This study analyzed the relationship between oxidative stress (imbalance between the production of free radicals and the antioxidant defenses of the body), tuberculosis and the role of green tea extract in repairing the damage caused by oxidative stress. The experiments were performed with mice. The results showed that there are high levels of oxidative…

Vitamin E reduces the risk of stone formation in tuberculosis patients

Summary This study analysed oxidative stress – the imbalance between the production of free radicals and the body´s ability to counteract their harmful effects through antioxidants – in tuberculosis patients, which is a predisposing factor for renal stone formation. Patients were divided in four groups: healthy people, tuberculosis patients a day before treatment, tuberculosis patients…

Blood levels of antioxidants are reduced in tuberculosis patients

Summary This study evaluated the blood levels of antioxidants (vitamins C, E and glutathione) in tuberculosis patients and healthy persons. Reduced levels of antioxidants were found in tuberculosis patients who, consequently, were more susceptible to oxidative stress, which is an imbalance between the production of free radicals and the body´s antioxidant defences.
