[The lateralization effect of oxytocin on the functional activity of paired visceral organs in rats]

Following unilateral intranasal oxytocin administration, asymmetric alterations in some functional parameters of the adrenal glands, testis, lungs and heart, occurred. The lateralization of alterations was dependent on the side of oxytocin injection and the side of paired organ arrevgenent. Possible pathways of intranasal oxytocin administration effects on visceral organs as well as causes of their asymmetry, are discussed.
