Влияние температурного фактора на эмбриональное развитие центральных NO-оргических структур у гомойотермных организмов

Abstract

The aim of this work was the study of the formation of NO-ergic systems of the frontal hypothalamus of duck embryos as the representative of homoiotermic birds in the period of the embryo development on this process. The experiments showed that the subthalamic area of 23-day-old duck embryos contains NADFH-d/CNO - positive neurons. It was also found out that 20-dayold embryos incubated at low temperature had CNO activity. This fact should be taken account for further investigation of influence of NO-dependent mechanisms in embryonic ontogenesis on thermoregulation under the influence of warmth, cold with the aim of correlation of embryonic development.
