Abstract
Data on serotonin content and its metabolism in serum and
duodenum in rats with glutamate-induced obesity (GIO)
are limited. The work aimed to investigate the prophylactic
effect of periodic course administration of the multiprobiotic
“Symbiter acidophilus” concentrated on the content of
serotonin and indicators of its metabolism in the blood
serum and duodenum in rats with GIO. It was found that the
concentration of serotonin and tryptophan in the blood serum
of rats with GIO decreased against the background of an
increase in monoamine oxidase activity. Under the influence of
periodic administration of a multiprobiotic to rats after neonatal
administration of monosodium glutamate, the concentration
of serotonin in the blood serum increased, although it did not
reach the control level. And the concentration of tryptophan
in the blood serum in this group of rats was restored to the
level of the intact control, which contributed to an increase
in the concentration of serotonin. One of the reasons for the
increase in the concentration of serotonin in the blood serum
in rats against the background of periodic administration of a
multiprobiotic after neonatal administration of monosodium
glutamate was a decrease in the activity of monoamine
oxidase. In rats with GIO, the content of serotonin in the
duodenal homogenate increased with a simultaneous decrease
in the content of tryptophan and an increase in the activity of
monoamine oxidase in comparison with the control group
of rats. In rats, after neonatal administration of monosodium
glutamate against the background of periodic administration
of a multiprobiotic in the duodenal homogenate, the serotonin
content decreased, the tryptophan content increased, and the
monoamine oxidase activity decreased compared with the
group of rats after neonatal administration of monosodium
glutamate. In the duodenal homogenate of rats with GIO,
tryptophan hydroxylase and indoleamine-2,3-dioxygenase
activities decreased, and tryptophan decarboxylase activity
did not undergo statistically significant changes. In rats, after
neonatal administration of monosodium glutamate against
the background of periodic administration of a multiprobiotic
in the duodenal homogenate, tryptophan hydroxylase and
indoleamine-2,3-dioxygenase activities increased, and
tryptophan decarboxylase activity did not change.
