The present invention generally relates to the field of diseases associated with impaired salivation, and to compositions that can be used for the treatment or prevention of such diseases. One embodiment of the present invention relates to compositions containing sialic acid for the treatment and/or prevention of diseases associated with impaired salivary flow.
Many people live to old age in good health. But as aging in the body is a lot of functional and structural changes, and not every person can easily cope with these changes. The reasons for individual differences and diverse, and include genotype, nutrition and behavior.
Aging is associated with functional changes in neurons and progressive loss of neurons of the Central and peripheral nervous system.
A typical condition, often associated with age, is a feeling of dryness in the mouth, due to the deficiency of salivation.
A feeling of dryness in the mouth can be closely linked to problems with swallowing, which further reduces the willingness of the individual to consume normal foods in adequate amounts to maintain good health.
Consequently, in this area there is a need for compositions that can be used in AWANA for the treatment or prevention of problems associated with impaired salivation.
The inventors decided to meet this need.
Therefore, the present invention was to provide compositions which are available to all, whom it may be entered without the risk of unwanted side effects, and which is inexpensive and can be used to increase salivary flow, especially in the elderly.
The task was achieved by the object of the invention independent points. Dependent items additionally develop the present invention.
Sialic acid (SiAc) are a family of charged monosaccharide with a chain of nine carbon atoms, derivatives of neuraminic acid (NeuAc). NeuAc is the only sialic acid formed in the body in vivo. As in other vertebrates, for example, are N-glycolylneuraminic acid (NeuGc).
Currently, sialic acid is often used in the field of child nutrition. Currently, sialic acid is often used in the field of child nutrition. For example, the possible participation of SiAc in the cognitive development of children was summarized in the work of Wang (Wang, W. and Brand-Miller, J. (2003) Eur.J.Clin.Nutr. Nov; 57(11): 1351-69). In short, the studies compared infants fed breast milk and infant formula, the software is Aravali, higher content of NeuAc in breast milk, compared with normal infant formula, correlates with an increased content of NeuAc in the saliva and brain babies. However, behavioral effects in the dietary Supplement NeuAc people lack. However, it is assumed that adding to cow's milk NeuAc will give cow's milk attributes of human milk, which may affect brain development in children.
Natural sources rich NeuAc are human milk, elephant milk, Indian Buffalo milk, meat, eggs and fish.
The inventors have introduced sialic acid to old rats. Old animals showed loss of salivary flow compared with young animals. Surprisingly, the feeding of sialic acid leads to increased stimulated the salivation, which is the salivation found in young animals.
Therefore, one embodiment of the present invention is a composition comprising a sialic acid for the treatment and/or prevention of diseases associated with impaired salivation.
The disease is associated with impaired salivation may be selected from the group consisting of dysphagia, xerostomia, and combinations thereof.
Dysphagia is a swallowing disorder characterized by difficulty training is the swallowing mouth, or difficulty in moving material from the mouth to the stomach. It also includes problems in positioning food in the mouth. Dysphagia is due to problems in the nervous or muscular control. It often happens, for example, after a stroke and treatment of cancer head/neck. Dysphagia threatens nutrition and hydration and can lead to aspiration pneumonia and dehydration.
Xerostomia is the medical term meaning a feeling of dry mouth due to decreased function of salivary flow. Chronic dry mouth can be uncomfortable and lead to serious health problems. Dry mouth can cause difficulties in the sensation of taste when chewing, swallowing and speech. If untreated, severe dry mouth can lead to increased levels of dental caries and infections of the mouth, such as candidiasis.
The preferred form of sialic acid is N-acetylneuraminic acid.
N-acetylneuraminic acid has the following synonyms and abbreviations: o-sialic acid; 5-acetamido-3,5-dideoxy-D-glycero-D-galacto-2-nonulosonic acid, 5-acetamido-3,5-dideoxy-D-glycero-D-Galaktionova acid; acetylneuraminic acid, N-acetyl-neuraminic, N-acetylneuraminic acid; NANA and Neu5Ac.
Preferred may be the enrichment of the ingredient and/or composition of sialic acid.
One embodiment n is the standing of the invention consists in the composition, containing protein fraction containing N-acetylneuraminic acid-related peptide/protein skeleton, enriched in threonine, for the treatment and prevention of diseases associated with impaired salivation.
Enrichment threonine means that the content of threonine higher than average prevalence of it in protein mass in humans. For example, the content of threonine can be enhanced at least by 10% compared with the average content of threonine protein mass in humans.
Thus, threonine may be, at least, 6,3 molar % of the amino acids in the protein fraction.
For example, threonine may be present in an amount of from about 8 to 22% of the total number of amino acids.
The protein fraction can optionally contain N-acetylneuraminic acid from about 7 to 25 wt.%.
N-acetylneuraminic acid may be represented in licensesand form. For example, N-acetylneuraminic acid may be represented in the form of related glycoproteins and/or proteoglycans.
In accordance with a particularly preferred embodiment of the present invention containing N-acetylneuraminic acid (NeuAc) protein fraction is characterized peptide/protein skeleton, enriched in threonine (the content of which is from 8 to 22% of the total number of amino acids) and NeuAc, sod the neigh which ranges from 7 to 25 wt.%.
N-acetylneuraminic acid may be represented in the form of oligosaccharide ingredient, which, for example, contains glikozilirovanie amino acids and peptides of the General formula, RnSacmwhere R is an amino acid residue; Sac is a monosaccharide selected from the group containing N-acetylneuraminic acid, N-atsetilgalaktozamin and galactose; n has a value from 1 to 10 with the proviso that if the value of n is 1, R is a residue of threonine or serine, and if n has a value from 2 to 10, the peptide contains at least one residue of threonine or serine; m has a value from 2 to 4; and N-acetylneuraminic acid accounts for at least 15 molar percent of the ingredient.
Preferably n has a value from 1 to 3, a m has a value of 3 or 4.
The ingredient contains at least 15 molar percent of sialic acid, as part sacharides circuit associated with a hydroxyl group of threonine or serine. Sialic acid can be part of a chain, or may itself be a Deputy monosaccharide units in the chain.
Preferably, if oligosaccharide ingredient contains the following monosaccharides: -
|Connection||The molar percentage|
|N-acetylase cozamin (GalNAc)||20-25|
|N-acetylneuraminic acid (NeuAc)||40-17,5|
Oligosaccharide ingredient may contain from 20 to 25 molar percent of the mixture of serine and threonine.
Oligosaccharide ingredient may contain the following glycosylated amino acids or peptides: -
Oligosaccharide ingredient of the invention can be prepared using either joint or sequential hydrolysis of CGMP by ectoprocta and endoproteases to obtain a mixture of free amino acids and peptides with a chain length from 2 to 10 and using nanofiltration hydrolyzed mixture to maintain the fraction having a molecular weight from 1000 to 2000 daltons.
CGMP itself is a byproduct of cheese making, in which whole milk is processed by the enzyme rendina to precipitate casein; In this process CGMP cleaved from K-casein and remains in solution with serum proteins. This product is known as sweet whey. CGMP may be separated from the whey by any method known in this field. A suitable method is described in European Pat is NTE No. 986312.
Without being bound by theory, the authors suggest that the protein fraction containing N-acetylneuraminic acid-related peptide/protein skeleton, enriched in threonine, for example, licensesand N-acetylneuraminic acid, is preferred in comparison with the free N-acetylneuraminic acid, for the following reasons. Free N-acetylneuraminic acid leads to very fast, "sharp" absorption and systemic increase in concentration of N-acetylneuraminic acid runs fast recovery levels of circulating N-acetylneuraminic acid by increased its excretion in the urine. Protein fractions containing N-acetylneuraminic acid-related peptide/protein skeleton, enriched in threonine, avoids this. For example, licensesand N-acetylneuraminic acid reaches all segments of the bowel, leading to slow the “long” absorption of N-acetylneuraminic acid along the entire length of the intestine, including the lower small intestine and large intestine.
The composition may be introduced to the elderly.

The composition may also contain probiotic microorganism and/or prebiotics such as fructo-oligosaccharides, galactooligosaccharides, pectins and/or their hydrolysates.
Prebiotics are what I particularly preferred in the compositions containing probiotics, because the presence of probiotics and prebiotics produces a synergistic effect.
"Probiotic" means preparations of microbial cells or components of microbial cells with a beneficial effect on health or the health of the host body. (Salminen S, Ouwehand A. Benno Y. et al “Probiotics: how should they be defined” Trends Food Sci. Technol. 1999:10 107-10).
All probiotic microorganisms can be used in accordance with the present invention. Preferably, they are selected from the group consisting of Bifidobacterium, Lactobacillus, Streptococcus and Saccharomyces or mixtures thereof, in particular selected from the group consisting of Bifidobacterium longum, Bifidobacterium lactis, Lactobacillus Acidophilus, Lactobacillus rhamnosus, Lactobacillus paracasei, Lactobacillus johnsonii, Lactobacillus plantarum, Lactobacillus salivarius, Enterococcus faecium, Saccharomyces boulardii and Lactobacillus reuteri or mixtures thereof, preferably selected from the group consisting of Lactobacillus johnsonii (NCC533; CNCM 1-1225), Bifidobacterium longum (NCC490; CNCM 1-2170), Bifidobacterium longum (NCC2705; CNCM 1-2618), Bifidobacterium lactis (2818; CNCM 1-3446), Lactobacillus paracasei (NCC2461; CNCM 1-2116), Lactobacillus rhamnosus GG (ATCC53103), Lactobacillus rhamnosus (NCC4007; CGMCC 1,3724), Enterococcus faecium SF 68 (NCIMB101415) and mixtures thereof.
Under the "prebiotic" refers to food substances which promote the growth of probiotics in the gut. They are not destroyed in the stomach and in the upper part of the intestine or not adsorb to the LCD tract accepting their persons, but they fermenti is described gastro-intestinal microflora and/or probiotics. Prebiotics, for example, defined in the work of Glenn R.Gibson and Marcel .Roberfroid, Dietary Modulation of the Human Colonic Microbiota: Introducing the Concept of Prebiotics, J. Nutr. 1995 125: 1401-1412.
Prebiotics, which can be used in accordance with the present inventions nothing special limited and include all food substances that promote the growth of probiotics in the gut. Preferably, they can be selected from the group consisting of oligosaccharides, optionally containing fructose, galactose, mannose; dietary fiber, particularly soluble fiber, soy fiber; inulin; or mixtures thereof. The preferred prebiotics are fructo-oligosaccharides, galactooligosaccharides, isomaltooligosaccharide, xylooligosaccharide, soybean oligosaccharides, glycosylceramide, lactosucrose, lactulose, platinochloride, maltooligosaccharide, gums and/or their hydrolysates, pectins and/or their hydrolysates.
It was found that the effect of sialic acid in the composition of the present invention will be essentially dependent on the dose. Small quantities will produce smaller effects, and large amounts can be so large that the body will not be able to use all provided SiAc acid. For example, the exact amount provided by SiAc will depend on the patient to be treated and its condition.
Although in General any to icesto SiAc will produce a beneficial effect, it was found that particularly preferred if the sialic acid present in the composition in an amount of 1 mg to 250 mg/g dry weight of the composition.
Sialic acid can be entered in a daily amount of 1 mg to 2 g/kg body weight, preferably of 0.025-0.8 g of body weight of the subject to treatment of the patient.
The person skilled in the art will understand that you can freely combine all the characteristics described here present invention, without departing from the expanded scope of the invention. In particular, the characteristics described for applications of the present invention can be applied to the compositions of the present invention and Vice versa.
Additional advantages and features of the present invention is illustrated in the following examples and figures.
The figure 1 shows that older rats show less activity of cholinergic neurons, which is measured by stimulating the production of saliva per unit time, compared to young adult rats, but show a significantly higher neuronal activity upon receipt of a diet rich in sialic acid. Presents mean values and standard error of the mean. N=9-10; ∗ indicates significant difference at p=0,0035 when comparing 3 and 24 months on the control diet and when p=0,0024 when comparing 24 monthly control and sialic (Si) diet on T-test.
Figure 2 again shows that pilocarpine stimulates salivation in young rats (3 m) and old rats (24 m)receiving the control diet (empty columns) or enriched NeuAc diet (filled columns) for 3 weeks. Shown are mean values and standard error of the mean (N=8-10). 2 factory the ANOVA test showed a significant age effect (p=0,0364) and the effects of treatment (p=0,0037) and nearly significant interaction effect (p=0.0550). Please note that the bait NeuAc increases stimulated salivation in old rats is much more efficient than in young adult rats.
Information confirming the possibility of carrying out the invention
Young adult (3 months) and aged rats (24 months old) were fed a semisynthetic diet containing sialic acid in a concentration of 0.15 g/100 g diet (control) or semi-synthetic diet supplemented with sialic acid to a final concentration of 0.9 g/100 g diet (Sia).
After 3 weeks of experimental diet was assessed neuronal activity of cholinergic neurons. To this end, rats were injected with pilocarpine (IE, 1.5 mg/kg body weight for 24 months in rats and 2 mg/kg body weight for 3 months in rats). Pilocarpine is a muscarinic antagonist acting on cholinergic neurons, which leads to salivation. This was chronometrically collection of stimulated saliva. the via is approximately 7 minutes collection stopped.
As seen in figures 1 and 2, old animals showed less stimulated salivary flow compared with young animals. When the consumption of sialic acid old animals reached similar to young animals values of stimulated salivary flow. This indicates that feeding of sialic acid promotes functional recovery of cholinergic neuronal function, which decreases with age.
The findings show that the proper salivation was restored in older animals by providing them with sialic acid through diet approach.
