As the popularity of probiotics, research on mechanisms of probiotics is becoming more and more in-depth. It is necessary to figure out what and how these strains can do. Using loperamide-induced constipation mouse model, the effects and mechanisms of probiotics complex (Lactobacillus rhamnosus LR-168, Lactobacillus acidophilus LA-99 and Bifidobacterium animalis BB-115) were investigated. Fifty BABL/c male mice aged six-week-old were used to test alleviation effect of probiotics complex. Firstly, five groups were randomly divided: blank group (saline), model (loperamide), positive control (loperamide + Bifidobacterium animalis BB12: 5×108 CFU), low-dose group (loperamide and probiotics complex: 5×108 CFU) and high-dose group (loperamide and probiotics complex: 5×109 CFU). Extended defecation time of first black stool was determined as the criterion for success of constipation modeling. Then, the data of defecation performance such as small intestinal transit rat, number of black stools and weight of black stools were collected. Based on the enzyme-linked immunosorbent assay, gastrointestinal peptide neurotransmitters and cytokines were analyzed. In regard to the potential effect of constipation, which unbalanced levels of aquaporin 3 (AQP3) and c-kit could bring out, quantitative real-time polymerase chain reaction was used to explore the mechanism behind, preliminarily. In the light of the criterion for the success of constipation modeling, it drew a conclusion that modeling of slow transit constipation mouse got success with loperamide induced. From the analysis of physiological changes, defecation performance was improved significantly in constipation mice after gavage with probiotics complex, specifically in small intestinal transit rate, number of black stools and weight of black stools. When the hypotheses about mechanisms of probiotics complex focused on the connection between gastrointestinal peptide and constipation, the secretion of excitatory neurotransmitters (substance P, gastrin and motilin) and inhibitory neurotransmitters (vasoactive intestinal peptide, somatostatin and endothelin 1) was observed. Outstanding variations were detected among model group and other groups, with the secretion of excitatory neurotransmitters increased and inhibitory neurotransmitters decreased, compared with model group. There was no obviously difference in cytokines reported in each group, but a slight decline in model group, elucidating a latent balance ability of probiotics. The transcription levels of AQP3 and c-kit, which could affect the transport of water and colonic peristalsis, were lifted notably after intervention with probiotics. With the intragastric administration of the probiotics complex, not only the defecation performance got improved, but also the levels of neurotransmitters and cytokines related to constipation were balanced. The probiotics complex could be taken as a preparation with great prospects for alleviating slow transit constipation.
