Abstract
Various types of adaptive behavior during the prepubertal period were analyzed in the offspring of rats receiving chronic injections of serotonin (5-HT) reuptake inhibitor fluoxetine, 5-HT1A receptor agonist buspirone, or their combination starting from gestation day 9 and subjected to immobilization stress from the 15th day of pregnancy until delivery. Prenatal stress increased pain sensitivity, prolonged inflammatory pain response, and increased the levels of anxiety and depression. Chronic administration of drugs acting through 5-HT1A receptors to pregnant rats improved the studied behavioral parameters in their offspring. Differences in the pain sensitivity were found between the effect of drug combination and each of them separately, and in the level of depression between combined administration and fluoxetine alone.
