Abstract:
Objective :To learn the regulatory effect of Lactobacillus plantarum JX025073.1 on intestinal flora and blood lipid in mice, so as to provide the basis for the nutritional intervention of probiotics in hyperlipidemia population.
Methods :Thirty male ICR mice were randomly divided into a control group, a model group and a intervention group. The mice in the control group were fed with basic diet, and in the other two groups were fed with high fat diet. The mice in the intervention group was given 0.4 mL of Lactobacillus plantarum JX025073.1 fermentation liquid by gavage every day, and in the other two groups were given 0.4 mL of normal saline. The body weight of mice, the mass of heart, liver, spleen and kidney organs were weighed, and the organ index was calculated. The contents of total cholesterol (TC), triacylglycerol/triglyceride ( TG ), low density lipoprotein cholesterol ( LDL-C ) in serum, TC, TG in liver and in feces were determined by biochemical analyzer. Bifidobacterium, Lactobacillus and Escherichia coli in feces were cultured and counted.
Results :After 42 days, compared with the control group, The mice in the model group had higher body weights, higher levels of TC, TG and LDL-C in serum, higher levels of TC, TG in liver and in feces, more Escherichia coli, less Bifidobacterium and less Lactobacillus ( P<0.05 ). Compared with the model group, the mice in the intervention group had lower body weight, lower levels of TC, TG and LDL-C in serum, lower levels of TC in liver, less Escherichia coli, higher levels of TC in feces, more Bifidobacterium and more Lactobacillus ( P<0.05 ).
Conclusion :Lactobacillus plantarum JX025073.1 can effectively regulate the blood lipid and intestinal flora of mice fed with high fat diet.
