Abstract

In the past 2 years powerful evidence has emerged to suggest that nitric oxide functions as a neurotransmitter in both the central and peripheral nervous systems. Recent evidence suggests that it may play a role in mediating forms of synaptic plasticity such as long-term potentiation in the CA1 region of the hippocampus, and long-term depression in the cerebellum. Abnormal secretion of nitric oxide may be responsible for the neurotoxicity mediated by NMDA receptors that results in the pathophysiology of strokes and neurodegenerative diseases.

      Moreover, VIP is a potent dilator of choroidal vessels (Nilsson and Bill, 1984) and smooth muscle relaxant, potentially enabling ICN to regulate IOP by both choroidal blood flow (Flugel et al., 1994; Riva et al., 1997) and choroidal thickness. Similar circadian changes in ocular morphology and IOP were found in marmoset (Nickla et al., 2002) and human (Chakraborty et al., 2011). Significant correlations were seen between axial bulbus length and choroidal thickness as well as between axial length and IOP in human, also the amplitude of these changes is lower.

      On injection in the paraventricular (PVN), NMDA not only increases number of penile erections, it also leads to an increased concentration of nitric oxide (NO) metabolites in the region [21]. Calcium [Ca2+] channel coupled NMDA receptors [22] mediate an increased calcium concentration thereby contributing to the NO synthase (NOS) activation. While, propofol increases NMDA-mediated [Ca2+] response in the pyramidal cell layer [23].
