The Influence of Maternal Hypoxia and Buspirone during Pregnancy on Cognitive Abilities and a Stress Response in Adult Male Offspring.
Spatial learning, memory, and reactivity of the hypothalamic-pituitary-adrenocortical system (HPA axis) were studied in adult male rats, whose mothers during pregnancy were subjected to acute moderate normobaric hypoxia, or repeated injections of buspirone, an agonist of type 1A serotonergic receptors (5HT1A), or their combination. Prenatal treatment with buspirone in rats with prenatal hypoxia impaired learning ability during the first day of 5-day training. A decrease in the effectiveness of long-term memory in comparison with short-term memory was revealed in two groups of rats: prenatal treatment with buspirone in combination with hypoxia and injection of physiological saline without hypoxia. The effectiveness of long-term memory and the level of corticosterone in response to stress did not differ between the groups, which can indicate adaptation of the 5HT1A receptor and the HPA axis to the prenatal buspirone and normobaric hypoxia during ontogeny.
期刊介绍:
Bulletin of Experimental Biology and Medicine presents original peer reviewed research papers and brief reports on priority new research results in physiology, biochemistry, biophysics, pharmacology, immunology, microbiology, genetics, oncology, etc. Novel trends in science are covered in new sections of the journal - Biogerontology and Human Ecology - that first appeared in 2005.
World scientific interest in stem cells prompted inclusion into Bulletin of Experimental Biology and Medicine a quarterly scientific journal Cell Technologies in Biology and Medicine (a new Russian Academy of Medical Sciences publication since 2005). It publishes only original papers from the leading research institutions on molecular biology of stem and progenitor cells, stem cell as the basis of gene therapy, molecular language of cell-to-cell communication, cytokines, chemokines, growth and other factors, pilot projects on clinical use of stem and progenitor cells.
The Russian Volume Year is published in English from April.
