The Impact Factor measures the average number of citations received in a particular year by papers published in the journal during the two preceding years. 2017 Journal Citation Reports (Clarivate Analytics, 2018) IF: 2.4 To calculate the five year Impact Factor, citations are counted in 2017 to the previous five years and divided by the source items published in the previous five years. 2017 Journal Citation Reports (Clarivate Analytics, 2018) 5-Year IF: 2.8 The Immediacy Index is the average number of times an article is cited in the year it is published. The journal Immediacy Index indicates how quickly articles in a journal are cited. Immediacy Index: 0.5 The Eigenfactor score, developed by Jevin West and Carl Bergstrom at the University of Washington, is a rating of the total importance of a scientific journal. Journals are rated according to the number of incoming citations, with citations from highly ranked journals weighted to make a larger contribution to the eigenfactor than those from poorly ranked journals. Eigenfactor: 0.00049 The Journal Citation Indicator (JCI) is a single measurement of the field-normalized citation impact of journals in the Web of Science Core Collection across disciplines. The key words here are that the metric is normalized and cross-disciplinary. JCI: 0.59 SJR: 0.429 SNIP: 0.507 CiteScore™:: 3.9 H-Index: 49

RÉSUMÉ

Oxygen free radicals and related reactive species have been implicated in the etiology of many diseases, such as atherosclerosis, neurodegenerative disorders, and cancer. Antioxidant enzymes exist in cells to protect against the effects of these free radicals and other oxygen-derived species, which are produced during the oxidative stress. Tea (Camellia sinensis) is the most commonly consumed beverage worldwide. Both green and black tea are known to possess many pharmacological properties, including antioxidant, antipyretic, antibacterial, and antineoplastic effects. In the present study, the preventive effects of black tea extract (BTE) was evaluated in Swiss albino mice against 7,12-dimethyl benz(a)anthracene (DMBA)-induced oxidative stress. The animals were given 0.5%, 1%, and 1.5% BTE as the sole source of drinking solution for 1 week prior to the administration of DMBA, which was given orally as a single dose of 50 mg/kg body weight. At the end of the study period, the liver, kidney, and prostate tissues were dissected out for the determination of antioxidant enzyme levels (catalase, superoxide dismutase, glutathione reductase, glutathione-S-transferase), and lipid peroxidation. A dose-dependent protective effect of BTE against DMBA-induced depletion in enzymes activity was observed in all three tissues examined. Similarly, a significant dose-dependent inhibition of the lipid peroxidation caused by DMBA was observed in the BTE-administered animals in all three tissues examined. Our results revealed that BTE provides protection against oxidative damage induced by xenobiotics.
