Abstract:

Purpose: The objective of this study is to evaluate the regulatory effect of Lactobacillus plantarum F1208 on
gastrointestinal functions in constipated rats. Methods: Male Wistar rats were randomly divided into health group, constipation group,
senna group, and Lactobacillus plantarum high-, middle- and low-dosage groups. A rat model of loperamide hydrochloride-induced
constipation was established. Each group was treated with corresponding drugs at 2 mL/(kg•d) for 7 days. During the experiment, feed
intake, water intake, body quality increase, fecal number and water content, live bacterial count in feces and gastrointestinal transit
ratio were monitored. Results: The administration with Lactobacillus plantarum F1208 for 7 days in constipated rats significantly
improved the feed intake and water intake, promoted the growth and development of rats, increased the number and water content
of feces within 24 hours, restrained the growth of intestinal bowel enterobacter and enterbacteriaceae, and improved gastrointestinal
transit ratio. Conclusion: Lactobacillus plantarum F1208 has improved gastrointestinal functions in constipated rats.
Conclusion: Lactobacillus plantarum F1208 has improvement gastrointestinal function in constipation rats.

Key words: Lactobacillus plantarum, constipation, gastrointestinal function, rats
