So this experiment was designed to study the protective effects and mechanism of inactivated Lactobacillus (Lac) on myocardial ischemia\u2013reperfusion (I\u2013R) injury (MIRI). MIRI rat models were established by ligation of left anterior descending coronary artery for ~30 min and then, reperfusion for 120 min and divided into control group, model group, and Lac (106, 107, and 108 cfu\/kg) groups. At the end of the test, the creatine kinase (CK) activity, lactate dehydrogenase (LDH) activity, superoxide dismutase (SOD) activity and malondialdehyde (MDA) content were assayed by corresponding kits. The heart was obtained from rats and the myocardial infarction area was determined by TTC staining and myocardial endothelial cell apoptosis rate was determined by Tunel kit. Besides, A20, I\u03baB, nuclear factor (NF)-\u03baB, and nitric oxide (NO) synthase (NOS) were also assayed by Western blot. When compared with model group, Lac obviously reduces MIRI in the rat by reducing myocardial infarction area and the apoptosis rate of endothelial cells; reduce the serum CK, LDH, and MDA content; increase the serum SOD activity; and suppress NF-\u03baB signaling and NOS expression in the myocardial tissues. Lac pretreatment can inhibit lipid peroxidation and effectively improve MIRI caused by oxygen free radical through inhibiting NF-\u03baB signaling.<\/jats:p>","DOI":"10.1042\/bsr20171025","type":"journal-article","created":{"date-parts":[[2017,10,13]],"date-time":"2017-10-13T00:25:34Z","timestamp":1507854334000},"update-policy":"https:\/\/doi.org\/10.1042\/crossmark_policy","source":"Crossref","is-referenced-by-count":17,"title":["Inactivated <i>Lactobacillus<\/i> promotes protection against myocardial ischemia\u2013reperfusion injury through NF-\u03baB pathway"],"prefix":"10.1042","volume":"37","author":[{"given":"Ni","family":"Wang","sequence":"first","affiliation":[{"name":"Gerontology Department, Affiliated Hospital of Yan\u2019an University (Shanxi), No. 43 North Street, Yan\u2019an, Shanxi Province 716000, P.R.
