OBJECTIVES One cause of cigarette smoking is oxidative stress that may alter the cellular antioxidant defense system, induce apoptosis in lung tissue, inflammation and damage in liver, lung, and kidney. It has been shown that Chinese green tea (CGT) (Lung Chen Tea) has higher antioxidant property than black tea. In this paper, we will explore the preventive effect of CGT on cigarette smoke-indu...

peppermint (mentha piperita l.), a herbaceous and perennial species whichis produced mainly for the medicine and food. the peppermint plants were initiated from 10 cm-long rhizome cuttings followed by transferring into pots. the 48 h-treated plants with methyl jasmonate (mj) concentrations (0, 0.1, 0.5 mm) were assessed for their total soluble proteins, malondialdehyde (mda), chlorophylls a, b ...

Imbalance in the antioxidant defense system leads to detrimental consequences, such as neurological disorders. The Nrf2 signaling is known as a main pathway involved in cellular defense system. Nrf2 is a transcription factor that regulates oxidative stress response by inducing expression of various antioxidant enzyme genes. In this study, we screened several pure natural compounds for Nrf2 acti...

The aim of this work was to determine if the inhibition or stimulation of NO synthesis modulates liver damage induced by chronic lead intoxication. Lead nitrate (3.6 mg/kg, per os) was administered one time a day for 30 days to male Wistar rats with low and high resistance to hypoxia treated simultaneously with L-arginine (600 mg/kg, i.p.) or N-nitro-L-arginine (L-NNA, 35 mg/kg, i.p.) 30 min. b...

The latter is largely governed by the efficiency of antioxidant defense sy...

Background. The article presents a study of the antioxidant defense system liver rats under influence thiosulfonate esters: S-ethyl-4-amino­benzenethiosulfonate (ETS), S-allyl-4-aminobenzenethiosulfonate (ATS) and S-allyl-4-acetyl-aminobenzenethiosulfonate (AATS) at concentrations 50 100 mg per kg body weight. Thiosulfonate esters, which are synthetic sulfur-containing analogs allicin, exhibit ...
