“…The present study showed that the viscosity of the study groups had a mean and ± SD with the lowest value in the first group, and increase in the second group while in the third group showed the highest value. This result was in agreement with the results reported [5,17,[31][32][33] .…”

Aim: Aims of this research to study the effect of surface area on retention of complete denture. Materials and methods: Oral examination clinically, some properties of the physical and chemical of human unstimulated saliva have been evaluation. They constituted in three groups (25 in each the first and the third group) and (50 in the second group). The first group was healthy and aged (20-30) years, the second group was healthy and aged (50-70) years, also the third group aged (50-70) years but with systemic diseases. The following properties were studied: flow rate, pH, total protein, density, surface tension, viscosity and film thickness. The amount of total protein concentration was responsible for physical and chemical changes especially viscosity. There was a direct positive correlation between the amount of total protein and surface tension, viscosity, density and film thickness, while there was a negative correlation between total protein and with flow rate and pH. The measurement of force due to surface tension of these samples have been done by preparing two pairs of circular discs of (PMMA) of (5.2,6.5) cm in diameter and compare of force between these groups, also compare these physical analyses with mathematic analysis. Results: indicated that in both the first and the third groups, the physical and mathematic analysis for the retention showed there was non-significant changes while second group showed there was a significant changes. Conclusion: there was a positive correlation between force and wetted area and this force was due to the wettability and not to water sorption.

“…Daily saline infusion to retain Wharton’s duct patency cannot increase salivary flow of transplanted SMGs, which further indicates that transplanted SMGs are hypofunctional early after transplantation. Previous reports have noted that parasympathetic stimulation evokes a copious flow of saliva, whereas sympathetic stimulation produces a small amount of flow that is rich in protein (Kyriacou et al , 1988; Ekström, 1989; Lung, 1994; McCloskey and Potter, 2000), which indicates that acetylcholine plays a predominant role in regulating fluid and electrolyte secretion from salivary glands. We showed that carbachol could stimulate the secretion and reduce the injury of transplanted SMGs early after transplantation.…”

“…A similar effect was obtained after the prolonged intravenous infusion of NPY. On this basis, NPY was recognized as a factor influencing the secretory and vascular function of SMG in the dog (McCloskey and Potter 2000). Previously a vasoconstrictor effect of NPY on the blood vessels was found in some mammals including man (Lundberg et al 1982;Corder et al 1987;Morris and Murphy 1988;Fallgren et al 1989;Stjernquist et al 1991;Markiewicz 2003).…”

Sympathetic neurons projecting to the ovine submandibular gland (SMG) from the superior cervical ganglion (SCG) and middle cervical ganglion (MCG) were identified using retrograde tracing with fluorescent dye (Fast Blue). Antibodies to tyrosine hydroxylase (TH), dopamine beta-hydroxylase (DbetaH) and neuropeptide Y (NPY) were used to determine the immunochemical characteristics of SMG-innervating sympathetic neurons. Immunohistochemistry combined with the retrograde tracing revealed that the population of SMG-projecting neurons consist of four distinct sub-populations, but taking into account their possible different physiological properties only three major sub-populations can be distinguished. The vast majority of neurons in both ganglia are noradrenergic in nature (co-express TH and DbetaH). All examined TH-immunoreactive (IR) neurons also show immunoreactivity to DbetaH. Sub-population of noradrenergic neurons can be divided into NPY-IR and non-NPY-IR. Noradrenergic neurons expressing NPY may act as vasoconstrictors. The second sub-population of SMG projecting neurons in the ganglia studied consists of non-noradrenergic neurons (containing NPY, but not TH). It is known that these kinds of neurons may play a vasodilatory role. In both examined ganglia the third sub-population consists of non-TH-IR and non-NPY-IR neurons of unknown physiological function. Since no DbetaH immunoreactivity was found in any of TH- neurons these nerve cells can also be regarded as non-noradrenergic. It is possible that some neurons of the second as well as the third sub-population are cholinergic and some of them are non-noradrenergic/non-cholinergic in character.
