Effects of the perinatal exposure of Gum Arabic on the development, behavior and biochemical parameters of mice offspring

الملخص EN

The effects of the perinatal oral exposure to Gum Arabic (GA) on mice offspring was examined.

GA was added to the drinking water of pregnant female Swiss–Webster strain mice at doses of 1 and 4 g/kg body weight, starting from the first day of pregnancy.

The treatment continued until the fifteenth day after delivery, after which mothers were switched to plain tap water.

A number of tests were carried out on offspring starting one day after birth and extending up to postnatal day 30 (PD30).

Pups showed a reduced gain of body weight and delayed opening of the eyes in comparison to the control group and only pups exposed to 1 g/kg body weight GA had a faster appearance of hair.

Sensory motor reflex tests carried out during the weaning period (from day of birth to PD21) showed enhanced motor reflexes in pups exposed to GA.

During the adolescent period (from PD22 to PD30), offspring showed dose-dependent enhanced motor activity (on PD22), reduced anxiety and fear (on PD27) and slightly enhanced memory and learning abilities (on PD30).

Biochemical tests of a number of blood parameters were conducted during and after the weaning period (on PD15 and PD30, respectively).

Our results indicated that GA might have a hypoglycemic and a beneficial effect on red and white blood cell counts.

This study gives a first insight on the effect of GA consumption on offspring, providing a starting point for further studies.
