3.1 Behavioral test results
3.1.1 Effect of probiotics on the
rate of sugar-water preference in mother-infant separated offspring of
depressed-like rats
Pleasure deficit is one of the main symptoms of depression, and we
generally assess the symptoms of pleasure deficit in SD rats using
sugar-water preference experiments. The results of the sugar water
preference experiment showed that the sugar water preference rate
decreased in the MS+NS group compared with the CON+NS group, and the
difference was statistically significant (P <0.01);
after the intervention, the sugar water preference rate increased in the
MS+P group compared with the MS+NS group, and the difference
wasstatistically significant (P <0.01); compared with
the MS+P group, there was no significant change in the sugar water
preference rate of SD rats in the CON+NS group
(P >0.05). Figure 1.
