AI Article Synopsis
- The study aimed to examine how probiotics combined with riboflavin affect the intestinal barriers in rats after suffering scald injuries.
- Rats were divided into three groups: a control group, a treatment group receiving probiotics and riboflavin, and a scald control group, with various observations on bacterial translocation and intestinal health metrics.
- Results showed that the treatment group experienced significantly lower levels of bacterial translocation and improved intestinal health compared to the control group, indicating that probiotics and riboflavin help protect and repair intestinal barriers after injury.
Article Abstract
Objective: To investigate the effect and its possible mechanism of the supplementation of probiotics combined with riboflavin on the intestinal barriers of the rats after scald injury.
Methods: Seventy Wistar rats were used in the study and were randomly divided into scald control (SC, n = 30), scald and treatment (ST, n = 30) and normal control (NC, n = 10) groups. The rats in SC and ST groups were subjected to 30% TBSA III degree scald. 1.5 ml of isotonic saline suspension containing 5 x 10(12) CFU/L of Bifidobacteria, 5 x 10(10) CFU/L of Bacillus cereus and 5 mg/L of riboflavin was given to rats by gavage in ST group twice a day. For the rats in SC and NC group equal amount of isotonic saline was fed twice a day. The changes in the incidence of bacterial translocation, the amount of intestinal membranous flora, the synthesis and secretion of SIgA in the ileum, and the repair of injured intestinal mucosa were observed.
Results: The incidence of bacterial translocation in ST group was significantly lower than that in SC group (P = 0.000 - 0.025). The plasma level of endotoxin in ST group was markedly lower than that in SC group on 3 post-scald day (PSD) (P < 0.05). The amount of bifidobacteria in caecal membrane flora increased by about 20 to 40 fold, whereas the amounts of E. coli and fungi significantly decreased (P < 0.01). The membranous injury scoring was 3 to 0 on 5 PSD (P < 0.05), and the SIgA content in intestinal mucus returned to normal value on the 5th PSD (P < 0.01) in the ST group.
Conclusion: Supplementation of probiotics together with riboflavin could ameliorate translocation of bacteria and endotoxin in rats with scald injury, implying that the intestinal barrier function was effectively protected.

This study investigated the effects of on alleviating loperamide-induced constipation. To evaluate the efficacy of in Sprague-Dawley (SD) rats, fecal parameters, the intestinal transit rate, and changes in intestinal mucosal cells were measured through histological analysis. Additionally, serotonin levels, water absorption, tight junction-related gene expression, and the cecal short-chain fatty acid (SCFA) content were analyzed.

The gut microbiome has emerged as a growing focus of research and public health interest, leading to the frequent exploration of probiotic dietary supplements as potential treatments for various disorders, such as anxiety and depression. In the present report, changes in inflammation and microbiome composition were assessed in model mice exhibiting depressive-like behaviors that were exposed to the probiotic HBUAS52074. It was found that HBUAS52074 alleviated the severity of depressive-like behaviors while increasing serum 5-HT concentrations.

The objective of this study was to evaluate whether supplementation with probiotics over a 2-week period stabilizes the gut microbiota in dogs following prolonged cefovecin treatment. A significant number of clinical veterinarians prescribe oral probiotics to dogs in conjunction with systemic antibiotics with the intention of protecting against gut dysbiosis. The effects of antibiotics and probiotics in dogs have not been extensively studied, however, and the optimal treatment for gut dysbiosis remains uncertain.
