Abstract

The invention "Lactobacillus rhamnosus strain WKA55 and its use and product in preparing products for preventing and treating alcoholic liver damage" belong to the technical field of microorganisms. The present invention provides Lactobacillus rhamnosus WKA55 ( Lacticaseibacillus rhamnosus ) and its application in the prevention and / or treatment of alcoholic liver damage, and experiments have confirmed that Lactobacillus rhamnosus WKA55 has strong free radical scavenging ability, which can help the body to remove excess free radicals, improve antioxidant capacity, reduce liver damage. At the same time, it has strong adhesion ability of intestinal epithelial cells and improves intestinal barrier function.

Description

technical field [0001] The invention belongs to the technical field of microorganisms, and particularly relates to Lactobacillus rhamnosus strain WKA55 and its use and products in preparing products for preventing and treating alcoholic liver damage. Background technique [0002] Alcoholic liver damage, also known as alcoholic liver disease, is caused by long-term or heavy drinking, causing liver damage and causing liver disease. Alcoholic liver disease is a common liver disease. The main symptoms are alcoholic fatty liver disease, hepatitis, liver fibrosis, liver cirrhosis, and in more severe cases, it will deteriorate into liver cancer. Investigator Huang Shunling and others conducted an epidemiological and clinical investigation in Hunan Province and found that the rate of alcoholic liver disease was 4.36%, of which alcoholic liver cirrhosis was 0.68% and alcoholic hepatitis was 1.5%. Several studies have shown that alcoholic liver disease is associated with per capita a...
