The data on the effect of vanadium citrate, which is organic, on carbohydrate metabolism and the content of estradiol in the blood of rats, as well as the relationship between these indicators are missing. Therefore, the aim of the work was to study the effect of this compound on the activity of glucose-6-phosphate dehydrogenase, lactate dehydrogenase, estradiol content and to establish correlations between the activity of the studied enzymes and the estradiol content in pregnant female rats under the effect of vanadium compound. The study was carried out on 25 female Wistar rats Rattus norvegicus, divided into five groups: group I - non-pregnant females, group II – pregnant females consuming pure water without additives, groups III, IV, V - females which during the mating and pregnancy periods received the solution of vanadium citrate at the concentrations of 3.75, 15.63 and 62.5 μgV/kg of body weight, respectively. Our studies have shown that glucose-6-phosphate dehydrogenase, lactate dehydrogenase and estradiol content increase in pregnant females of group II compared to group I of non-pregnant animals. The increase in the activity of carbohydrate metabolism enzymes in pregnant females of group ІІ may be due to the activation of the pentosophosphate pathway and the intensification of glycolysis in erythrocytes. In pregnant females, the effect of vanadium citrate resulted in the decrease in the activity of glucose-6-phosphate dehydrogenase and lactate dehydrogenase in the blood of animals in groups IV and V, and the content of estradiol in the animals of all three experimental groups (III, IV, V), compared to group II of pregnant females. It has also been established that under the effect of this compound between glucose-6-phosphate dehydrogenase and lactate dehydrogenase activity in pregnant females there is a strong reverse correlation (r = -0.92), between lactate dehydrogenase activity and estradiol content – a weak correlation (r = -0.42 ), while between the content of estradiol and glucose-6-phosphate dehydrogenase activity there is a strong direct correlation (r = 0.74). The values of glucose-6-phosphate dehydrogenase activity in the animals of group IV, which received the solution of vanadium citrate at the concentration of 15.63 μgV/kg of body weight, was similar to that of the animals in group I. This may indicate the normalizing effect of vanadium citrate on the activity of glucose-6-phosphate dehydrogenase at the indicated concentration, which is probably due to the ability of the vanadium microelement to inhibit the activity of this enzyme. The decrease in lactate dehydrogenase activity in groups IV and V, compared to group II, may also be due to the effect of this compound. Vanadium citrate at the concentration of 15.63 μgV/kg of body weight caused the recovery of the enzyme activity to the values of the activity in group І. At this concentration, the most remarkable positive effect on the enzyme activity of carbohydrate metabolism and the content of estradiol is observed. Our studies allow to consider this vanadium compound as a potential dietary supplement for pregnant women.
