Abstract
The importance of Nitric oxide (NO) as a neurotransmitter acting on magnocellular neurons of the supraoptic nucleus (nmSON) became evident when the expression of nitric oxide synthase (NOS), oxytocin (OT) and vasopresin (VP) RNAm levels were increased by treating the cells with hyperosmotic solution. Currently, it is well known that NO has an indirect effect on the nmSON activity by acti…
