Study of Diabetic cutaneous wound healing in rats treated with Lactobacillus Casei and its Exopolysaccharide

Probiotics are live microorganisms (in most cases, bacteria) that are similar to beneficial microorganisms found in the human gut. They are also called "friendly bacteria" or "good bacteria". Lactobacillus derived from products, including culture supernatants have been used for their wound healing and antiviral properties as they are believed to boost energy and to be effective remedies for allergies, common cold, lactose intolerance, and have also been shown to reduce cholesterol levels and the risk of colon cancer. Therefore, the purpose of this experiment is to study the effect of Lactobacillus casei on Diabetic wound healing. This study was designed to investigate the amount of exopolysaccharide (EPS) production by L. Casei, L. Brevis, L. Bulgaricus and L. Plant arum from the genus Lactobacillus applying the phenol-sulfuric acid method and the antagonistic effects of these bacteria on some pathogenic bacteria. L. casei was selected for its high exopolysaccharide and fucoid colonise production. The animals were injected by streptozotocin at the dose of 55 mg/kg of the body weight intraperitoneal streptozotocin induced diabetes within 3 days by destroying the beta cells. Wistar male rats divided into 4 groups; 2 experimental groups, a control and a negative control (n = 6); and a full-thickness wound (1x 1cm) was made on the back of each rat. The current study showed a significant reduction in inflammation and a significant acceleration in wound healing on the rats treated by Lactobacillus casei as compared to control and negative control groups.
