Description
DESCRIPTION
AGENT FOR IMPROVING DETERIORATED PERIPHERAL SENSATION DUE TO
AGING AND/OR DISEASE
TECHNICAL FIELD
The invention relates to a skin sensitivity improving agent that includes a basic
protein fraction or a ed basic protein fraction as an active ingredient and
improves deterioration in peripheral sensation, and a skin sensitivity improving food,
drink, feed, or cosmetic that includes the skin sensitivity improving agent.
BACKGROUND ART
In recent years, an increase in age-related diseases such as osteoporosis,
dementia and the like has become a serious social issue along with aging of population.
Various drugs have been developed to prevent or improve such age-related diseases.
r, since drugs always need to take side effects into consideration, in recent years,
attempts have been made to prevent or improve age-related diseases through a change in
eating habits or intake of a specific food ingredient. For example, it is known that
osteoporosis is prevented or improved by intake of a basic protein contained in cow
milk (see Patent Document 1). A dementia therapeutic agent that prevents or improves
Alzheimer-type ia and contains sphingomyelin which is one of the phospholipids
containing relatively ntly in cow milk as an active ingredient has also been
known (see Patent Document 2).
oration in eral ion can be known as one of the lated
symptoms. The deterioration in peripheral sensation also occurs due to not only aging,
but also diseases such as diabetes and the like. Deterioration in peripheral sensation
may occur following troubles; for example, as it can’t feel hot immediately when
touching a hot object, a risk of burns or the like increases or the discovery of an injury
becomes delay due to deterioration in pain sensation. In recent year, in order to
decrease such a risk, s that improve deterioration in peripheral sensation due to
ageing or diseases have been conducted. For example, it has been reported that
sphingomyelinase or phosphatidylcholine-specifi'c phospholipase C, which are enzymes
that increase biosynthesis 0f endogenous ceramides promote differentiation of PC-12
cells which is one of the neural cell lines through the secretion of neurotrophic factors
from Swiss 3T3 fibroblast cells (see Non-patent nt 1). r, since
ceramides and the above enzymes are not food ingredients, it is necessary to take
account of safety. Therefore, a safe agent that is effective to improve deterioration in
peripheral sensation h daily intake or skin application has been desired.

fraction. The skin sensitivity improving agent according to the invention exhibits an
effect that improves deterioration in peripheral sensation.
EMBODIMENTS FOR CARRYING OUT THE INVENTION
The invention is characterized in that a milk-derived basic protein fraction or a
degraded milk-derived basic protein on are used as active ingredients. The
milk-derived basic protein fraction is ed from mammalian milk such as cow milk,
human milk, goat milk, or ewe milk, and the degraded milk-derived basic protein
fraction is obtained by treating the milk-derived basic protein fraction with a protease.
The milk-derived basic protein fraction has the ing properties.
1) The milk-derived basic n fraction comprises several types of proteins
having a molecular weight of 3,000 to 80,000 determined by sodium dodecyl sulfate
rylamide gel ophoresis (SDS-PAGE).
2) The milk-derived basic protein fraction includes proteins in an amount of 95
or less by treating a milk-derived basic protein fraction obtained by the above methods
with a protease such as pepsin, trypsin, or chymotrypsin, and optionally treating the
resulting product with a protease such as pancreatin or the like.
The milk-derived basic protein fraction Or the degraded erived basic
protein fraction may be used ly as the skin sensitivity improving agent according
to the invention. Note that the skin sensitivity improving agent may be further mixed a
raw material or the like that is normally used for drugs, food, drink, and feed, such as
saccharides, lipids, ns, vitamins, minerals, or , or the like, in on to the
milk-derived basic protein fraction or the degraded milk-derived basic protein fraction,
and the skin sensitivity improving agent may be prepared into a powdered drug,
granules, a tablet, a capsule, a drinkable preparation, or the like by a tional
method. The skin sensitivity improving agent may also be used in common
application form such as emulsion, cream, lotion, massage mask, or the like. The skin
sensitivity improving agent in preparation form may be prepared by a conventional
method while appropriately adding the milk-derived basic protein fraction or the
degraded milk-derived basic protein on used as an active ingredient in the
invention, and may be used as a cosmetic. Another component, e.g., ceramide,
sphingomyelinase, or sphingomyelin or the like that exhibits a skin sensitivity
ing effect may be used in combination with the milk-derived basic protein
fraction or the degraded milk-derived basic protein fraction. In the experiments
described later using mice, the peripheral sensation was improved by orally
administering the milk-derived basic protein fraction or the degraded erived basic
protein fraction in an amount of 10 mg/kg weight or more, and preferably 20 mg/kg
weight or more per mouse. Therefore, deterioration in sensation, particularly
peripheral sensation, is expected to be ed when an adult lly takes the
milk-derived basic protein fraction or the degraded erived basic protein fraction
in an amount of 10 mg/day or more, and preferably 20 mg/day or more, and thus it is
desired to take the above necessary quantity. When applying the milk-derived basic
protein fraction or the degraded milk-derived basic protein on to skin, the skin
liniment may contain the milk-derived basic protein on or the degraded
milk-derived basic protein fraction in an amount of 0.001 to 40 wt%, and preferably 0.1
to 10 wt%, based on the total amount of the skin nt.
A skin sensitivity improving food or drink according to the invention may be
produced by mixing the milk-derived basic protein fraction or the degraded
milk-derived basic protein on to a normal food or drink, such as yogurt,
milk-based drink, wafer, dessert or the like. It is preferable that the skin ivity
improving food or drink contain the milk-derived basic protein fraction or the degraded
milk-derived basic protein fraction in an amount of 0.5 to 2000 mg per 100 g of the
food or drink so that an adult can take the erived basic protein fraction or the
degraded milk-derived basic n fraction in an amount of 10 mg/day or more,
although the content of the milk-derived basic protein on or the ed
milk-derived basic protein fraction is appropriately determined depending on the type of
the food or drink. A skin ivity improving feed according to the invention may be
produced by adding the milk-derived basic protein fraction or the degraded
milk-derived basic protein fraction to a normal feed, such as livestock feed, pet food or
the like. It is preferable that the skin sensitivity improving feed contain the
milk-derived basic protein fraction or the degraded milk-derived basic protein fraction
in an amount of 0.5 to 2000 mg per 100 g of the feed so that the milk-derived basic
protein fraction or the degraded milk-derived basic protein fraction is taken in an
amount of 10 mg/day or more.
The method of mixing the milk-derived basic protein fraction or the degraded
erived basic protein fraction may not be particularly d. For example, the
milk-derived basic protein fraction or the ed erived basic protein fraction
is suspended or ved in deionized water, and the mixture is stirred and prepared in
the form of a drug, food, drink, or feed. The stirring/mixing conditions are not
particularly d as long as the milk-derived basic protein fraction or the degraded
milk-derived basic protein fraction is unifome mixed. The mixture may be
stirred/mixed using an ultra-disperser, a TK-homomixer, or the like. The solution
containing the composition may optionally be concentrated using an RO membrane, or
freeze-dried so that the solution can be easily used for a drug, food, drink, or feed. A
sterilization treatment conventionally used in the production of a drug, food, drink, or
feed may be employed in the invention. at sterilization may also be employed
for a powdery product. Therefore, it is possible to e drugs, food, drink, and
feed in various forms (e.g., liquid, gel, powder, or granules) that contain the
milk-derived basic protein fraction or the degraded milk-derived basic protein fraction
ofthe invention.
The invention is further described below by way of examples and test examples.
Note that the following examples are for illustrative purposes only, and should not be
construed as limiting the invention.
Example 1
A column (diameter: 5 cm, height: 30 cm) filled with 400 g of sulfonated
Chitopearl (cation-exchange resin; manufactured by Fuji ng Co., Ltd.) was
sufficiently washed with deionized water. 40 1 (liters) of unsterilized skim milk (pH
6.7) was passed through the column at a flow rate of 25 ml/min. The column was then
sufficiently washed with zed water, and a basic protein fraction adhered on the
resin was eluted with a 0.02 M carbonate buffer solution (pH 7.0) containing 0.98 M
sodium chloride. The eluate was desalted and trated using a reverse s
(RO) membrane, and freeze-dried to obtain 21 g ofpowdery milk-derived basic protein
fraction (Example product 1). The molecular weight of the milk-derived basic protein
fraction determined by sodium dodecyl sulfate polyacrylamide gel electrophoresis
AGE) was distributed in the range of 3000 to 80,000. The milk-derived basic
protein fraction had the composition shown in Table 1. The milk-derived basic protein
fraction was hydrolyzed using 6 N hydrochloric acid at 110°C for 24 hours, and the
amino acid composition of the milk-derived basic protein fraction was analyzed using
an amino acid analyzer (“L-8500” manufactured by i Ltd.). The results are
shown in Table 2. The protein composition ofthe milk-derived basic protein fraction
was analyzed by ELISA. As shown in Table 3, the milk-derived basic protein on
had a lactoferrin content and a lactoperoxidase content of 40% or more. The basic
protein fraction may be used directly as the skin ivity improving agent according
to the invention.

heat-sterilized at 121°C for 30 seconds was passed through the column at a flow rate of
l/min. The column was then sufficiently washed with deionized water, and a basic
n fraction adhered on the resin was eluted with a 0.1 M citrate buffer on (pH
.7) containing 0.9 M sodium chloride. The eluate was desalted and concentrated by
electrodialysis (ED), and freeze-dried to obtain 183 g of a powdery milk-derived basic
protein on (Example product 2). The milk-derived basic protein fraction thus
ed may be used directly as the skin sensitivity improving agent according to the
invention.
Example 3
50 g of the milk-derived basic protein on obtained in Example 1 was
dissolved in 10 l of led water. After the addition of 1% atin (manufactured
by Sigma), the mixture was reacted at 37°C for 2 hours. After completion ofthe
reaction, the protease was inactivated by heating the mixture at 80°C for 10 minutes to
obtain 48.3 g of a degraded milk—derived basic protein fraction (Example product 3).
The degraded milk—derived basic n fraction thus obtained may be used directly as
the skin sensitivity improving agent according to the invention.
Test Example 1
(Study on cell differentiation—promoting activity)
Swiss 3T3 cells, which is one of the fibroblast cell lines known to be present in
skin, were cultured for 2 days under the condition that Example product 1 of the
milk-derived basic n fraction or Example product 3 of the degraded milk—derived
basic protein fraction was added at a concentration of 0.03 to 1%, respectively
(Example t 1: group A, e product 3: group B). As a control, Swiss 3T3
cells were cultured for 2 days without adding Example product 1 of the milk—derived
basic protein fraction or Example product 3 of the degraded milk—derived basic protein
fraction (group C). PC—12 cells, which is one of the neural cell lines, were cultured
adding the culture medium of Swiss 3T3 cells, and morphological differentiation of the
PC-12 cells was observed.
As the results, PC-12 cells were highly differentiated when adding the culture
mediums ofthe group A or B. The above experiment was repeated several times, and
the difl'erentiation ratio was determined using an optical cope. It was confirmed
that 95% or more ofthe cells were differentiated in both cases of group A and B. '
contrast, PC-12 cells were not differentiated when adding the culture medium of the
group C. No differentiation was observed using an l microscope when the
experiment was repeated several times. It was thus confirmed that the milk-derived
basic protein fraction obtained in Example 1 and the ed milk-derived basic
protein fraction obtained in Example 3 promoteddifferentiation of PC-12 cells which is
one ofthe neural cell lines.
Test Example 2
(Study on skin sensitivity improving effect using experimental animals)
A skin ivity improving effect was evaluated by the hot plate test that is a
thermal stimulation behavioristic approach developed by Woolfe and MacDonald.
24-week-old hairless mice R-l) were divided into three groups (10 mice/group).
Example product 2 (milk-derived basic protein fraction) was orally stered to each
mouse using a sonde in an amount of 0, 10, or 20 mg/kg weight once daily for 4 weeks.
Each mouse was placed on a hot plate at 54°C, and the time elapsed until the mouse
made an escape behavior such as taking off the foot from the hot plate, standing up, or
jumping was measured. The m time of escape behavior positive reaction time
that is time until the mouse made an escape behavior after applying l stimulation
was set to 30 seconds. When the escape behavior positive reaction time was 30
seconds or more, the escape behavior positive reaction time was determined to be 30
seconds. The results are shown in Table 4.
TABLE 4

As shown in Table 4, the escape behavior positive reaction time tended to be
shortened when administering Example product 2 (milk-derived basic protein fraction)
in an amount of 10 mg, and significantly shortened when administering Example
product 2 (milk-derived basic n fraction) in an amount of 20 mg. It was thus
confirmed that deterioration in sensation, particularly peripheral ion, can be
prevented or improved by intake of Example product 2 derived basic protein
on).
Test Example 3
(Study on skin sensitivity improving effect by oral intake)
Healthy elderly persons (average age: 752t3) who suffered deterioration in

milk-derived basic protein fraction,
Group B: the subjects took the milk-derived basic protein fraction obtained in Example
1 in an amount of 10 mg for 6 weeks,
Group C: the subjects took the milk-derived basic protein fraction obtained in e
1 in an amount of 20 mg for 6 weeks,
Group D: the subjects took the degraded erived basic protein fraction obtained in
Example 3 in an amount of 10 mg for 6 weeks, and
Group E: the subjects took the degraded milk-derived basic protein fraction ed in
Example 3 in an amount of 20 mg for 6 weeks.
The pain sensation in the palm and the arch of the foot was measured with 4 criteria
(normal, deterioration I, deterioration II, and deterioration III) before the intake and
after the intake for 6 weeks with nce to the pain sensation in the medial side of the
arm using a pain/touch-pressure sensation measuring device (Algesiometer;
manufactured by Intercross Ltd.) in accordance with the instruction manual. A
questionnaire survey on an improvement in sensation in the hands was carried out to
each elderly person after the intake for 6 weeks. The results are shown in Tables 5 to
(Measuring method)
The pain ion was evaluated using five pins having different thickness at
five fiilcrum positions. The thinnest pin 1 was rolled along the medial side ofthe arm,
and the subject was asked about the degree of normal pain sensation.
The pin 1 was then rolled along the palm and the bottom ofthe foot while
sequentially changing the holder fillCI'llIIl on to determine the fillch position at
which the same pain sensation degree as the first pain sensation occurred.
(Evaluation )
The algesiometer is ed so that the pain sensation occurs to the same extent
between when rolling the pin 1 (fiilcrum: 50 g) along the medial side ofthe arm and
when rolling the pin 2 (fillcrum: 50 g) along the palm. The pain sensation was
evaluated as follows in accordance with the instruction manual. The pain sensation
was evaluated by , and the average points were calculated.
Normal (0 points): The same pain sensation ed when rolling the pin 2 (fiilcrum:
50 g).
oration I (1 point): The same pain sensation occurred when rolling the pin 1
(15110111111: 50 g).
Deterioration II (2 point): The same pain sensation occurred when rolling the pin 1
(fiilcrum: 60 g).
Deterioration III (3 point): The same pain sensation occurred when rolling the pin 1
(fiilcrum: 70 g).
