Presence of Atrial Natriuretic Peptides in Respiratory System

Atrial Natriuretic Peptide presence in parotid gland of human fetus at 13th week of development and in adult man

Our immunohistochemical study shows that atrial natriuretic peptide (ANP) is present in both human fetal and adult parotid gland. In the fetuses ANP is localized in cell clusters, while in adult parotid gland, the ANP is seen only in the wall of intra- and extralobular ducts. The results suggest that ANP might play a role in the differentiation of the parotid gland similarly as in brain and that during fetal growth ANP may play a role in the regulating the secretion of primitive salivary fluid, even if acini are still not developed.

Presence of Oxytocin, Vasopressin and Atrial Natriuretic Peptide and Their Modification in Rat Hypothalamic Paraventricular Nucleus During Resistance Training

Summary Many studies have demonstrated the physiological effects of oxytocin (OT), atrial natriuretic peptide (ANP) and vasopressin (VP) in the homoeostasis of body fluids during physical exercise. However, a little information is available about the related immunohistochemical changes in hypothalamic magnocellular neurosecretory system during and after the training. The aim of the present work was to study the immunohistochemical changes in OT, ANP and VP levels in the hypothalamic paraventricular nucleus during and after resistance exercise protocol. Three groups of Wistar rats were trained by a rung ladder protocol for 15, 30 and 45 days, respectively; a fourth group was left to rest for…

Results indicate that the insulin presence stimulates the ANP synthesis in pancreas of human foetuses from diabetic mothers. Aim of this work is to investigate the presence of Atrial natriuretic peptide (ANP) and insuli…

The somatotopy of the spinal cord: a comprehensive descrption.

For the benefit of medical students, in this paper we examine the somatotopic organization of the spinal cord, which shows a similar organization in mammalians. The dorsal horn is comprised of sensory nuclei with deutoneurons; the lateral horn contains preganglionic visceral motoneurons; the ventral horn is subdivided into a medial column innervating the paravertebral muscles, a central column, C3-C6, innervating the diaphragm, and a lateral column innervating the limb muscles. In the lateral column of the ventral horn, the dorsal motoneuron groups innervate the intrinsc arm muscles; the dorsal posterior motoneuron groups innervate hand muscles; the lateroventral motoneuron groups innervate…

Atrial natriuretic peptide (ANP) and oxytocin-expression in the adult rat and mouse cerebellum.

Abstract Background: Many studies are in the literature on the ANP and oxytocin-presence in the brain, but very few studies with controversial results are reported on the presence of these peptides in the cerebellum. This immunohistochemical study investigates on the ANP and oxytocin-presence in the cerebellum of the adult rat and mouse rodents. Results: This study, firstly, evidences the ANP- immunopositivity in cerebellar cortex of both rat and mouse rodents. In rat the molecular layer presents some few immunopositive fibers, but no neuron resulted immunopositive; the granular and Purkinje cells are immunopositive. In mouse the cerebellar cortex ANP-immunopositivity is present in all laye…

ANP PRESENCE IN THE HYPOTHALAMIC SUPRACHIASMATICUS NUCLEUS OF DEVELOPING RAT

In previous research, we studied both the oxytocin and vasopressin ontogeny in the hypothalamic supraoptic and paraventricular nuclei, and the ANP-ontogeny in the hypothalamic supraoptic nucleus. In this paper we evaluate the ANP-ontogeny in the rat hypothalamic suprachiasmatic nucleus; infact the suprachiasmatic nucleus it is known to synthesize vasopressin, a peptidic hormone involved in the homeostasis of the body fluids by an antagonistic role to ANP. Immunohistochemical techniques show that ANP is present in the hypothalamic suprachiasmatic nucleus of the rat at 18 degrees day of i.u. life and at 0 degrees to 3 degrees day of postnatal life. PCR analysis confirms the ANP-mRNA expressio…

Presence and interaction in tissues of atrial natriuretic peptide,oxytocin and vasopressin:new insights.

Atrial natriuretic peptide, oxytocin and vasopressin are three well known and widely studied molecules since many years. They have been fully characterised from a genetic and biomolecular point of view and a number of receptor-dependent functions have been recognised for them. Nevertheless, in the last years our group has conducted morphologic studies, using an immunohistochemical approach complemented by molecular biology techniques, and could show non-canonical localization and co-localization of these peptides in normal and pathologic tissues, that permitted us to postulate that they may be involved in a wider range of functions than usually assumed and not yet fully understood. In this …

ANP (Atrial Natriuretic Peptide) presence in the heart of a tunicate, Ciona intestinalis.

Atrial natriuretic peptide was found in the heart of vertebrates, we studied the ANP presence in the heart of Ciona intestinalis. This is animal is very important because of the its evolutionary position between invertebrates and vertebrates. ANP presence was only revealed in myoepithelial cells of the myocardium. Results suggest the hypothesis that ANP is present not only in the vertebrates but also in the invertebrates and in Ciona heart ANP might play a similar role like in the heart of vertebrates.

ANP and vasopressin -presence in the ciliary body of eye in the pig, (Sus domesticus)

The aqueous humor is produced in the ciliary body so, in this study we investigate on the ANP presence and vasopressin in the ciliary body of the pig eye since these peptide are involved in the homeostasis of the body fluids. The results show ANP-presence in the epithelial cells and in the endothelial cells of the blood vessels and VP-presence in the epithelial cells, in the endothelium of canal of Schelmm and in the muscle cells of the blood vessels. These peptides might regulate the synthesis and the composition of the aqueous humor and regulate the hydrodynamic flow and haemodynamic flow of the blood.

COX- Expression in the inflamed gingival tissue:Immunohistochemistry,Cytochemistry and Biochemistry test.

Prostaglandins (PG) are chemical mediators for most physiological and pathological responses ,including cytoprotection of the gastric mucosa, blood coagulation,inflammation and pain (1,2,3). E2 Prostaglandins (PG2) play an important role of pathogenesis of periodontal diseases, since PG2 determines vasodilatation and increased vascular permeability, oedema and erythema.Therefore,it is not surprising to find high levels of PG2 in inflamed gingival tissues.Indeed ,in inflamed gingival tissue,PG2 levels of the Gingival Fluid (GCF) are known to be higher in periodontitis than in healthy gingiva.Moreover ,in different parodontitis the high PG2 level of the GCF is related to periodontal ligament …

Oxytocin and vasopressin expression in the turbinates of patients with chronic sinusitis

Many peptides are present in the nasal mucosa, but few studies have investigated the presence or absence of the oxytocin and vasopressin peptides. This immunohistochemical study on the inferior turbinates of patients affected by chronic sinusitis shows, for the first time, that these peptides are present in the epithelium of both nasal mucosa and glands. Their presence could be related to the presence of atrial natriuretic peptide (ANP), like previously demonstrated in other organs such as heart and prostate, since in some circumstances they play in antagonism.
