°MATRIX ~AII~IING NEPHRITE JADE POWDER AS A MAIN
~~r~,n Field of the Invention The present invention relates to a matrix( ~) containing fine powder of nephrit jade as a main component.
More specifically, the present invention relates to the matrix containing fine powder of nephrite jade of very fine combination weave fibrous microstructure of cryptocrystaline tremolite type. By using the matrix, a variety of goods in the field of medical goods, utensile goods, equipments for leisure time, vessels, interior goods, agricultural goods, industrial goods, fishery goods, traffic goods, transportation goods, equipments for sports, electronic instruments, precision instrument, or the like can be prepared. The goods made of the matrix can show excellent effects of treating pathological sympthoms(headache, numb feeling, indigestion, insomnia, or the like), removing impurities(such as heavy metals), improving the quality of water, promoting the growth of plants by virtue of the inherent properties of nephrite jade.
Prior Art As is generally known, jade is largely divided into jadeite and nephrite jade.
Jadeite belongs to pyroxene family and has monoclinic system comprising silicic acid, aluminum oxide and soda. It is an intimate mass, and the hardness is comparable to that of crystal. It is transparent or translucent of black, blue green or green color. People usually says the jadeite as "jade".
Nephrite jade is an inorganic material having monoclinic system of inosilicates. The quality of nephrite jade is determined by the fine structure, and the finer the fibre, the better is the quality.
According to a German literature [Heady Bursius, " Die Magie der Edelsteine " and Mauda Palmer Die Verborgene, "KRAFF der KRISTALLE and der EDELSTEINE"] , the two different ores, jadeite an nephrite jade both comprises silicon and oxygen, as most of other jewels. However, jadeite is formed of granular crystals while nephrite jade consists of lots of crystals and aggregates of microparticles having fibrous, hair-like structure, In particular, nephrite jade comprises three elements, Ca, Fe and Mg, which are good for human body, while jadeite comprises sodium and aluminum components, Thus, It has been recently reported that nephrite jade, when attached to the body, provides a considerable effect to the treatment of hypertension, diabetes, circulating system disorder, heart disease and kidney disorder.
A classic of traditional oriental medicine, "Treasures in oriental medicine(~~)"describes that if jade is added to black rice liquor to alter the liquor to water, and intake of jade powder in a size like sesame . seed is good for the discharge of the waste material. Also it describes that when jade powder(1 part by volume), rice(1 part by volume) and white dew(1 part by volume) are cooked to rice in a copper vessel, the jade powder becomes water(so called jade-liquid, the "devine jade water").
"Plants of Devine AgricultureOl~ ~ ~)", "Plants of Tang Age(f~ ~
~)"and "List of Basic Plants( ~-~J~ )" describes that intake of jade powder in a size like sesame seed enriches five viscera and six entrails and completely discharges the waste materials. In addition, it is effective to digestive system by remove heat from stomach, and it is good for the treatment of bronchus asthma, body fever and heavy feeling in the chest as well as thirst. When jade powder is taken for a long time, body becomes easy and light, function of lung is enhanced, making voice by vocal cords becomes easier. Also, it is good for throat, nutrition of hair, functions of five viscera and six entrails and treatment of nervous diseases such as stress.

Generally, nephrite jade powder having the particle size of 100-950 mesh is preferably used. If the shape of the molded article is complicated, or increased ductility is required, for example, in case that the article has a small thickness, more fine particles(about 250-950 mesh) are preferable used, while 100-500 mesh powder may be added in order to prepare a general molded article. If the particle size is higher than the range, it is disadvantageous because the surface roughness of the article becomes larger, while the particle size is lower than the range, difficulties occurs in the pulverization.
The amount of nephrite jade added to the raw materials(resin)of the articles is desirably 5-30%. If the amount is less than 5°k, the effect of nephrite jade can not be expected. The larger the amount, the better effect of nephrite jade occurs. However if the amount is beyond the range, the cost of the product is increase owing to the high price of nephrite jade.
The nephrite jade powder used in the present invention may be originated from the remaining stone of nephrite jade after making the products of personal ornaments, vessels or sculpture, on order to lower the production cost to enhance the economics. By using the matrix, a variety of goods for practical use which have the inherent properties of nephrite jade may be obtained with far lower cost than that of the products made of nephrite jade itself. Besides, the products made of the matrix of the present invention have enhanced mechanical or thermal properties(such as heat resistance, tensile strength, compression strength, etc) as compared to those not containing nephrite jade.
The nehrite jade powder used in the present invention is crytocrystalline tremolite of 6180 , having a composition shown in the following Table 2.

Fig. 3E shows the effect of the jade container on meat colour when pork was stored at 0 C or 4 C for 21 days.
As can be seen from the results, drip loss was much less in pork stored in the jade bowl and tended to be considerably reduced as time passed by, regardless of the storage temperature. As an important indicator of postmortem change of muscles, pH normally reduces immediately after slaughter and then remains as high as 6.5-6.8. In the present experiment, the type of the container did not seem to affect pH change(though pH at 4 C was higher than that at 0 C)and the VBN value(which indicates the degree of protein denaturation) of pork directly. However, the TBA value (which indicates the degree of lipid oxidation) was kept lower in pork stored in the jade bowl regardless of the storage temperature. Meat colour was measured by a colour different meter due to absorption and reflection of meat colour pigment. The ' CA 02258312 1999-O1-22 aE value was lower in the control(plain bowl group) than in the jade bowl group at 0 C and no consistent tendency was observed in pork stored at 4 C
though the ~E value at 0 C was lower than that at 4 C.
This might have resulted from higher metmyoglobin formation due to more dehydration caused by the high temperature.
From the experiment, if containers made of jade or packing materials(such as polyvinyl film) coated with jade powder are used in storing food, sanitary and quality might be maintained in the distribution of corruptible food, thereby lengthening the shelf life and enhancing the safety.
Experimental Example 5 The experiment is to examine the effects of a jade mug prepared from Examples 1-3 of the present invention, which might change the taste attributes of a beverage (commercial instant coffee) when the beverage is served in a jade container. The experiment was performed by Department of Food & Nutrition of Chung-Ang University and Korea Food Research Institute.

The molding process for synthetic resin matrix according to the present invention is a well-known method and follows the methods described in the Table 1 below.
Table 1 Injection molding (thermoplastic resin) Press molding(thermosetting resin) Transfer molding(thermosetting resin) Raw materials Extrusion molding(Thermoplastic for resin) the synthetic Blow molding (thermoplastic resin) resin Vaccum molding(thermoplastic resin) Compression molding(thermoplastic resin) Deposite molding(thermoplastic resin) The particle size of the nephrite jade powder used in the preparation of the matrix according to the present invention may be selected as considering the shape and use of the molded article. Generally, nephrite jade powder having the particle size of 100-950 mesh is preferably used. If the shape of the molded article is complicated, or increased ductility is required, for example, in case that the article has a small thickness, more fine particles(about 250-950 mesh) are preferable used, while 100-500 mesh powder may be added in order to prepare a general molded article. If the particle size is higher than the range, it is disadvantageous because the surface roughness of the article becomes larger, while the particle size is lower than the range, difficulties occurs in the pulverization.
The amount of nephrite jade added to the raw materials(resin)of the articles is desirably 5-30%. If the amount is less than 5°k, the effect of nephrite jade can not be expected. The larger the amount, the better effect of nephrite jade occurs. However if the amount is beyond the range, the cost of the product is increase owing to the high price of nephrite jade.
The nephrite jade powder used in the present invention may be originated from the remaining stone of nephrite jade after making the products of personal ornaments, vessels or sculpture, on order to lower the production cost to enhance the economics. By using the matrix, a variety of goods for practical use which have the inherent properties of nephrite jade may be obtained with far lower cost than that of the products made of nephrite jade itself. Besides, the products made of the matrix of the present invention have enhanced mechanical or thermal properties(such as heat resistance, tensile strength, compression strength, etc) as compared to those not containing nephrite jade.
The nehrite jade powder used in the present invention is crytocrystalline tremolite of 6180 , having a composition shown in the following Table 2.

The experiment was performed by Korea Food Research Institute. Details are described below:
Pork was stored either in a jade-containing synthetic resin bowl or in a plain bowl(control) for 0,4,7,14 or 21 days at 0 C or 4 C. One hundred grams(100g) of pork cut from the ham part was kept in each container, while the drip loss, meat colour, pH, volatile basic nitrogen (VBN : protein denaturation) and lipid oxidation(TBA) were measured. The results are shown in Table 9 bellow:

Fig. 3E shows the effect of the jade container on meat colour when pork was stored at 0 C or 4 C for 21 days.
As can be seen from the results, drip loss was much less in pork stored in the jade bowl and tended to be considerably reduced as time passed by, regardless of the storage temperature. As an important indicator of postmortem change of muscles, pH normally reduces immediately after slaughter and then remains as high as 6.5-6.8. In the present experiment, the type of the container did not seem to affect pH change(though pH at 4 C was higher than that at 0 C)and the VBN value(which indicates the degree of protein denaturation) of pork directly. However, the TBA value (which indicates the degree of lipid oxidation) was kept lower in pork stored in the jade bowl regardless of the storage temperature. Meat colour was measured by a colour different meter due to absorption and reflection of meat colour pigment. The ' CA 02258312 1999-O1-22 aE value was lower in the control(plain bowl group) than in the jade bowl group at 0 C and no consistent tendency was observed in pork stored at 4 C
though the ~E value at 0 C was lower than that at 4 C.
This might have resulted from higher metmyoglobin formation due to more dehydration caused by the high temperature.
From the experiment, if containers made of jade or packing materials(such as polyvinyl film) coated with jade powder are used in storing food, sanitary and quality might be maintained in the distribution of corruptible food, thereby lengthening the shelf life and enhancing the safety.
Experimental Example 5 The experiment is to examine the effects of a jade mug prepared from Examples 1-3 of the present invention, which might change the taste attributes of a beverage (commercial instant coffee) when the beverage is served in a jade container. The experiment was performed by Department of Food & Nutrition of Chung-Ang University and Korea Food Research Institute.
The details are described below:
1~ Object of the experiment To examine the change in a jade mug or a plain mug(control).
2) Test method: Paired Preference Test ' CA 02258312 1999-O1-22 - to test preference of one sample over the other sample - test attributes: test, aroma, aftertaste, colour 3J Sensory panels - 20-25 senior students majored in food & nutrition at Chung-Ang University in Korea(who are experienced with the panel test and have knowledge on the test method) 4) Test period - March to June, 1996 - Once a week - Totally 10 times were performed 5) Test container and type of beverage - A jade mug and a plain mug : both having same appearance - Beverage : instant coffee (Taster's choice) 6) Sample preparation - 1 tea spoon of coffee was mixed to 1/2 cup of 100 C water.
7~ Statistics : T-test (p ~ 0.05) Results 1. Taste : coffee contained in the jade mug imparted a much less bitter taste (p~0.5).
2. Colour & Aftertaste : The jade mug tended to give a better colour ' CA 02258312 1999-O1-22 and aftertaste, but statistically non-significant.
3. Aroma : The plain mug have a better coffee aroma than the jade mug, but statistically non-significant.
*_ Table 10 below sho~rs the effect of the jade mug on the sensory attributes of coffee.
Table 10 12.6 12 11.7 107106 11.8 .7 9.6 .6 8 Jade ~Cont ro Taste Aroma Aftertaste Color Conclusion The jade mug see to make the taste of coffee mild (which is proved to be statistically significant). Aftertaste and colour of the coffee contained in the jade mug was similar to or better than that contained in a plain mug (not statistically significant). Aroma of coffee contained in a plain mug was better than that in jade mug (not statistically significant).
Experimental Example 6 The experiment is to investigate the effect of jade-containing synthetic-resin tiles and supernatant jade water after precipitation of jade powder on the reproduction and growth in rats when jade tiles were placed on the cage and jade water was fed instead of tap water. It was performed by Korea Food Research Institute. The details are described below.
Thirty male and female Sprague Dawley rats (9 weeks old)were assigned to each treatment. Rats of group A were housed in the cages placed with jade tile and provided with tap water. Rats of group B were fed with supernatant jade water after precitation of jade powder(2 mg/ml tap water), but no jade t i le was placed on the cage. The rats of group C formed a control group(no jade tiles and no jade water). Rats were mated for nine days and then male rats separated and sacrificed for sperm concentration and motility tests. The results are shown in Table 11 below:

Parturition rates of groups A and B (90°6, respectively) mere higher than those of group C (80~).
The number of male puppies were higher in group A and B(3 puppies more.
respectively), although rats of group C gave birth to several (6-8) more puppies. Also the length of time from mating to parturition was shorter in group A rats than the other two groups of rats.
Besides these findings, sperm concentration and motility in both rats of group A and B were superior to C. However, the effects for both jade tile and jade water treatments at the same time were not investigated in this study.
In conclusion, the results suggest that jade tile and jade water seem to affect the reproduction and growth of rats: either jade tile or jade water treatment groups had shown better indices of reproduction and growth. It would be very valuable to investigate these effects further for future application, These findings may be applied as basic data to the improvement of reproductive efficiency and to strengthen the sperm concentration and motility rate.
Experimental Example 7 The experiment is to investigate the relieving effect of various jade products on the symptoms of diabetes mellitus when various jade products were applied to streptozotocin-induced diabetes mellitus rats. It was performed by Korea Food Research Institute. The details are described below. (See Fig s 4A,4B,4C,4D 4E and 4F) ' CA 02258312 1999-O1-22 To thirty-two(32) Sprague Dawley rats weighing 252-292g were given streptozotocin [35-40mg(per kg of body weight) dissolved in 0.1 M citrate buffer of pH4.0] peritoneally to induce diabetes. Seven days after administration of streptozotocin, rats showing blood glucose levels higher than 25 mg/d~ were selected based on uropaper (Eieken Chemical Co., Ltd, Japan). Four experimental groups of 5 rats each were employed for 50 days of experimental period. Group A rats were injected with l.Om~ of distilled jade water peritoneally (pH 6.4) each day. Rats of group B were housed in cages placed with jade tiles on the bottom throughout the experiment. Rats of group C were fed with supernatant jade water after precipitation out of jade powder as everyday drinking water. Group D rats as a control did not have any treatment. Diets fed were commercial rat chow, ad the rats were cared for according to the general practices. Rats were sacrificed on day 50 and blood was collected from the abdominal aorta. Plasma were prepared from centrifuging blood containing heparin at 5,000 rpm for 15 min, after standing the blood at room temperature for 30 min, Organs(liver, kidney) taken out were weighed and recorded. Measurements tested in blood plasma were HBA(plasma a -hydroxybutyrate), FFA(free fatty acids), cholesterol, HDL-cholesterol and triglyceride, The content of HBA is qualitatively analyzed by measuring the increase of Absorbance(OD) of NADH, which is ' CA 02258312 1999-O1-22 produced by oxidation by ,B -hydroxybutyrate dehydrogenase, at 340nm. Lipids in blood were measured by using a clinical kit(Eiken Chemical Co., Ltd., Japan).

Kidney weight of group C was the lowest among the treatments besides control. Liver weight was also increased owing to the induction of diabetes, but liver weight was the lowest in rats fed with jade water.
Concentrations of blood glucose, ketone body and FFA were higher in the order of groups A, B, C and D. Blood plasma cholesterol and triglyceride concentration had followed the same tendency (A7 B~ CJ D) to the above parameters mentioned. From the results, rats fed with fade water(group C)showed comparatively lower values of all the parameters measured rather than the other two experimental groups, and blood cholesterol and FFA
concentrations were lower in rats of group C than the control without any jade treatment.
TC(blood cholesterol) and TG(neutral lipid)concentration was in the order of A~ B~ C~ D. The result of glycemic index by blood sugar reaction after meals changes dependent upon the researchers. However, in the experiment, though commercial blended feed(TMR)was fed without considering glycemic index of cereals, C group fed with jade water showed an effect for alleviating hyperlipidemia, one of the diabetic symptoms. There occurred no difference of HDL-cholesterol concentration between the test groups.
The administration of jade water to Streptozotocin-induced diabetic rats showed effects of preventing the reduction of body weight, preventing enlargement of kidney or liver as well as alleviating hyperlipidemia, one of the diabetic symptoms.

As described in above Experimental examples, the nehrite jade powder used in the matrix according to the present invention showed the following effects:
1) In the test for freshness of pork, drip loss was much less in pork stored in a jade bowl and tended to be considerably reduced as time passed, regardless of the storage temperature. VBN(protein denaturation) and TBA value(which indicates the degree of lipid oxidation) was kept lower, too, in pork stored in a jade bowl;
2) In the sensory test concerning test, the jade mug seems to make the taste of coffee mild(which is proved to be statistically significant, p <0.5);
3) In the experiment to investigate the effect: of jade products on the reproduction of rats(SD rate), the jade treated rats showed superior ability of parturition, reduced time from mating to parturition and superior sperm concentration and motility to the control group.
4) In the experiment to investigate the relieving effect of jade on the symptoms of diabetes mellitus when various jade products were applied to streptozotocin-induced diabetes mellitus rats, rats fed by jade water showed lower lipid concentration in blood, so that jade products may be used to alleviate hyperlipidemia, one of the diabetic symptoms.
5) In the study to investigate the effects of nephrite jade on lowering blood pressure of spontaneously hypertensive rats(SHR) when jade beddings were used, significant hypotensive effect has been shown as compared to the control group. It was confirmed that systolic blood pressure has been reduced by about 16 mmHg.
Also as shown in experimental example 3 to 8, use of the nephrite jade powder as the interior finishing board for a refrigerator showed an excellent power-saving effect. Especially, the molded articles showed excellent effects in treating pathological symptoms.

Experimental Example 6 The experiment is to investigate the effect of jade-containing synthetic-resin tiles and supernatant jade water after precipitation of jade powder on the reproduction and growth in rats when jade tiles were placed on the cage and jade water was fed instead of tap water. It was performed by Korea Food Research Institute. The details are described below.
Thirty male and female Sprague Dawley rats (9 weeks old)were assigned to each treatment. Rats of group A were housed in the cages placed with jade tile and provided with tap water. Rats of group B were fed with supernatant jade water after precitation of jade powder(2 mg/ml tap water), but no jade t i le was placed on the cage. The rats of group C formed a control group(no jade tiles and no jade water). Rats were mated for nine days and then male rats separated and sacrificed for sperm concentration and motility tests. The results are shown in Table 11 below:

Parturition rates of groups A and B (90°6, respectively) mere higher than those of group C (80~).
The number of male puppies were higher in group A and B(3 puppies more.
respectively), although rats of group C gave birth to several (6-8) more puppies. Also the length of time from mating to parturition was shorter in group A rats than the other two groups of rats.
Besides these findings, sperm concentration and motility in both rats of group A and B were superior to C. However, the effects for both jade tile and jade water treatments at the same time were not investigated in this study.
In conclusion, the results suggest that jade tile and jade water seem to affect the reproduction and growth of rats: either jade tile or jade water treatment groups had shown better indices of reproduction and growth. It would be very valuable to investigate these effects further for future application, These findings may be applied as basic data to the improvement of reproductive efficiency and to strengthen the sperm concentration and motility rate.
Experimental Example 7 The experiment is to investigate the relieving effect of various jade products on the symptoms of diabetes mellitus when various jade products were applied to streptozotocin-induced diabetes mellitus rats. It was performed by Korea Food Research Institute. The details are described below. (See Fig s 4A,4B,4C,4D 4E and 4F) ' CA 02258312 1999-O1-22 To thirty-two(32) Sprague Dawley rats weighing 252-292g were given streptozotocin [35-40mg(per kg of body weight) dissolved in 0.1 M citrate buffer of pH4.0] peritoneally to induce diabetes. Seven days after administration of streptozotocin, rats showing blood glucose levels higher than 25 mg/d~ were selected based on uropaper (Eieken Chemical Co., Ltd, Japan). Four experimental groups of 5 rats each were employed for 50 days of experimental period. Group A rats were injected with l.Om~ of distilled jade water peritoneally (pH 6.4) each day. Rats of group B were housed in cages placed with jade tiles on the bottom throughout the experiment. Rats of group C were fed with supernatant jade water after precipitation out of jade powder as everyday drinking water. Group D rats as a control did not have any treatment. Diets fed were commercial rat chow, ad the rats were cared for according to the general practices. Rats were sacrificed on day 50 and blood was collected from the abdominal aorta. Plasma were prepared from centrifuging blood containing heparin at 5,000 rpm for 15 min, after standing the blood at room temperature for 30 min, Organs(liver, kidney) taken out were weighed and recorded. Measurements tested in blood plasma were HBA(plasma a -hydroxybutyrate), FFA(free fatty acids), cholesterol, HDL-cholesterol and triglyceride, The content of HBA is qualitatively analyzed by measuring the increase of Absorbance(OD) of NADH, which is ' CA 02258312 1999-O1-22 produced by oxidation by ,B -hydroxybutyrate dehydrogenase, at 340nm. Lipids in blood were measured by using a clinical kit(Eiken Chemical Co., Ltd., Japan).

Kidney weight of group C was the lowest among the treatments besides control. Liver weight was also increased owing to the induction of diabetes, but liver weight was the lowest in rats fed with jade water.
Concentrations of blood glucose, ketone body and FFA were higher in the order of groups A, B, C and D. Blood plasma cholesterol and triglyceride concentration had followed the same tendency (A7 B~ CJ D) to the above parameters mentioned. From the results, rats fed with fade water(group C)showed comparatively lower values of all the parameters measured rather than the other two experimental groups, and blood cholesterol and FFA
concentrations were lower in rats of group C than the control without any jade treatment.
TC(blood cholesterol) and TG(neutral lipid)concentration was in the order of A~ B~ C~ D. The result of glycemic index by blood sugar reaction after meals changes dependent upon the researchers. However, in the experiment, though commercial blended feed(TMR)was fed without considering glycemic index of cereals, C group fed with jade water showed an effect for alleviating hyperlipidemia, one of the diabetic symptoms. There occurred no difference of HDL-cholesterol concentration between the test groups.
The administration of jade water to Streptozotocin-induced diabetic rats showed effects of preventing the reduction of body weight, preventing enlargement of kidney or liver as well as alleviating hyperlipidemia, one of the diabetic symptoms.

As described in above Experimental examples, the nehrite jade powder used in the matrix according to the present invention showed the following effects:
1) In the test for freshness of pork, drip loss was much less in pork stored in a jade bowl and tended to be considerably reduced as time passed, regardless of the storage temperature. VBN(protein denaturation) and TBA value(which indicates the degree of lipid oxidation) was kept lower, too, in pork stored in a jade bowl;
2) In the sensory test concerning test, the jade mug seems to make the taste of coffee mild(which is proved to be statistically significant, p <0.5);
3) In the experiment to investigate the effect: of jade products on the reproduction of rats(SD rate), the jade treated rats showed superior ability of parturition, reduced time from mating to parturition and superior sperm concentration and motility to the control group.
4) In the experiment to investigate the relieving effect of jade on the symptoms of diabetes mellitus when various jade products were applied to streptozotocin-induced diabetes mellitus rats, rats fed by jade water showed lower lipid concentration in blood, so that jade products may be used to alleviate hyperlipidemia, one of the diabetic symptoms.
5) In the study to investigate the effects of nephrite jade on lowering blood pressure of spontaneously hypertensive rats(SHR) when jade beddings were used, significant hypotensive effect has been shown as compared to the control group. It was confirmed that systolic blood pressure has been reduced by about 16 mmHg.
Also as shown in experimental example 3 to 8, use of the nephrite jade powder as the interior finishing board for a refrigerator showed an excellent power-saving effect. Especially, the molded articles showed excellent effects in treating pathological symptoms.
