Nitric oxide (NO) in bird embryogenesis: physiological role and possibilities of practical use

Nitric oxide (NO) is generated in human and animal tissues from L-arginine. Its known effects include mediation of the parasympathetic nervous system (effects of a??t?lch?line), smooth muscle tonus, apoptosis, and tissue differentiation. The physiological effects of NO attract significant theoretical and practical interest in medicine and agriculture due to its possible regulation of physiological functions.   It is known that embryo development involves intensive NO production, but the exact r
