The present invention relates to a composition for stimulating bone growth comprising the extract of crude drug complex as an active ingredient, more precisely a composition for stimulating bone growth comprising the extract of crude drug complex composed of Dipsaci radix, Astragalus membranaceus and Acanthopanax senticosus.
Growth indicates the increase of height, which is stimulated by nutrition and growth hormones. The nervous system including the brain secreting growth hormone is fast growing in childhood and since then, the growth becomes slow. The growth continues until the age of puberty in most human. So, if nutrition is not taken enough particularly from childhood to the age of puberty, the full growth cannot be expected. For nutritional balance, numbers of growth stimulating health foods have been sold. However, these health foods are prepared simply by combining many components for stimulating growth and the effect is not satisfactory.
The growth of the length of long bone determines the height and bone structure, which is regulated by a specific mechanism. In particular, the growth of the epiphyseal growth plate of long bone is the most important index for the growth of bone length. The growth plate is composed of proliferation zone involved in the proliferation of chondrocytes, maturation zone involved in the growth of chondrocytes and hypertrophic zone involved in the hypertrophy of chondrocytes, and the interrelation among those zones leads to the growth of the length of long bone (Loveridge, N, J. Anim. Sci. 77, 190-196, 1999).
The growth hormone has been used for the treatment of dwarfism. Since the late 1985, the growth hormone prepared by genetic recombination has been on market, suggesting that the mass production and supply of such growth hormone has been accomplished. Besides, there was no risk of getting a disease by taking the growth hormone. So, the growth hormone produced by genetic recombination has been recently used as a therapeutic agent for treating diseases caused by deficiency of growth hormone. GHRP-6 (growth hormone releasing peptide-6, His-D-Trp-Ala-Trp-D-Phe-Lys-NH2), the growth hormone secretion stimulator, which is composed of 6 amino acids having growth hormone secreting activity has been developed based on enkephalin (Bowers C Y. et al., Endocrinology, 114, 1537-45, 1984). According to the previous report, this drug can be absorbed when it is oral-administered, even if the absorption rate is very low (Noriko I. et al., Life Science, 47, 29-36, 1990). The studies continued and other growth hormone secretion stimulators, GHRP-1 (Ala-His-D-β-Nal-Ala-Trp-D-Phe-Lys-NH2) and GHRP-2 (D-Ala-D-β-Nal-Ala-Trp-D-Phe-Lys-NH2) composed of 6 modified peptides, have been developed. Even if the in vivo activity of these drugs was excellent, the absorption rate according to the oral administration was only 2-3%, indicating that it is still limited for oral administration.
Dipsaci radix is the root of Dipsacus asper Wall that is a perennial herb belonging to Dipsacaceae. The major components are succinic acid, betonicine, shanzhiside methyl ester, akebia saponin D and daucosterol. According to the traditional oriental medicine, Dipsaci radix has been used as a drug that has the effect of invigorating liver and kidney, strengthening muscle and bone, forming muscle and bone and treating waist and kidney diseases; in other words it has been used as a drug for making bones and muscles strong by invigorating the body particularly when bones and muscles were weakened. So, a method for separation and purification of asperosaponin H1, a kind of glycoalkaloid, derivative that is one of the major components of Dipsaci radix and has the activity of stimulating the secretion of growth hormone is described in Korean Patent No. 10-0436219. There are references illustrating the effect of Dipsaci radix (Yu, et al., Effect of the Physiologically Active Compounds in Dipsaci radix on Cell Cycle Regulation in Human Gingival Fibroblasts, Journal of Korean Academy of Periodontology, 35(1), 87, 2005; Kim, et al., The Effects of Dichloromethane fraction of Dipsaci radix (DFPR) on differentiation of Mouse Calvarial Cell, Journal of Korean Academy of Periodontology, 34(4), 791, 2004; Ahn, et al., Effects of the Dipsaci radix on the Aged ovariectomized Rat Model of Postmenopausal Osteoporosis, Journal of Korea Association of Herbology, 9(1), 181, 1994; Chun-Hsu Yao, Effects of Dipsaci radix on the osteoblast differentiation, J Biomed Master Res Part B: Appl Biomaster 75B: 277-88, 2005). So, it is presumed that the effect of Dipsaci radix on the growth is achieved by stimulating the osteoblast differentiation to induce bone growth. However, the effect of Dipsaci radix on the growth plate has not been exposed, yet.
Astragalus membranaceus is the root, whose periderm is almost peeled, of the perennial herb Astragalus membranceus Bunge belonging to Leguminosae. The major components are sucrose, glucoronic acid, different kinds of amino acids, bitter substance, mucosubstance, choline, betaine and folic acid. According to the traditional oriental medicine, Astragalus membranaceus has the effect of strengthening the body, for example it helps the treatment of weak body, sweating, furuncurus, dipsesis, abdominal pain, kidney weakness, ear pus, diabetes, pain, loss of taste, lack of appetite, hemorrhoid, red eye, malaria, proctoptosis, metrorrhagia, colporrhea, menstrual irregularity, prenatal/postbirth symptoms, discharge of phlegm, headache, petrified lung, heart burning, dysentery, juvenile diseases, etc. There are references that explain the effect of Astragalus membranaceus on hematopoiesis (Ma R. et al., J Tradit Chin Med. September; 3(3):199-204, 1983), on antioxidation (Li, Chun-Ying., J. Agr. Sci., Inst. Agr. Sci. Kangwon Nat. Univ., 15:103, 2004), on the osteoblast differentiation in rabbit (Xu C J. et al., Zhong Nan Da Xue xue Bao Yi Xue Ban, August; 29(4):489-91, 2004), on the prevention of osteoporosis of ovariectomized rat (Kim C. et al., Arch Pharm Res. November; 26(11):917-924, 2003). However, the effect of Astragalus membranaceus on the growth plate has not been exposed, yet.
Acanthopanax senticosus indicates the dried root, rhizome and bark of the deciduous shrub Acanthopanax senticosus (RUPR. et MAXIM) HARMS belonging to Araliaceae. It contains such glycosides as carotene, ligustrin, 7-methyl-6,8-dimethylcoumarineglycoside, galactoside, syringaresinol di-o-beta-D-glucoside and caryophyllen and chlorogenic acid, flavone, refined oil and polysaccharide as major components. The pharmacological actions of Acanthopanax senticosus are sedation, anti--stress, immune enhancement, smooth muscle relaxation, and anti-inflammation (State Administration of Traditional Chinese Medicine: Zhonghuabencao, Shanghai, Shanghai Scientific and technical Publishers 1998). In addition, Acanthopanax senticosus is also known to have the effect of strengthening spleen and sprit, invigorating kidney, improving weak waist, invigorating, relaxation and helping blood circulation without interruption, so that it has been widely used for the treatment of exhaustion resulted from weakening of lung and spleen, Weakness of lower limbs and back caused by lack of appetite and weak spleen and kidney, poor blood circulation resulted from the loss of stamina, weak heart and spleen, inappetence, sleeplessness or bad dreaming, weak muscles and bones in child, Dropsical leg, and rheumatoid arthritis (State Administration of Traditional Chinese Medicine: Zhonghuabencao, Shanghai, Shanghai Scientific and technical Publishers, 1998). Acanthopanax senticosus has the effect of improving tonic with invigorating mentally and physically and the preventive effect on disease owing to the capability of increasing non-specific resistance (Wagner, 1985) as well as the activity of lowering blood sugar and inhibiting cancer and hypotension. Unlike ginseng, Acanthopanax senticosus does not have such side effect as insomnia since it does not make people nervous (Loydia, Vol. 32. 1, 1969). Acanthopanax senticosus has protective effect against the toxicity caused by parathion (Ferguson P. W. et al., 1984) and irradiation (Miyanomae T et al., 1988), and has anti-coagulation activity (Yun-Choi H. S. et al., 1987) and has the effect of lowering blood lipid level (Sui D. Y. et al., 1994). Among the components of Acanthopanax senticosus, acanthoic acid inhibits platelet coagulation, inflammation, and the release of superoxideanion (Kang H. S. et al., Cell Immuno. Vol. 170, No. 2, p 212, 1996). In the meantime, chlorogenic acid and syringaresinol di-o-beta-D-glucoside reduce the risk of gastric ulcer caused by cool bath stress (Fujikawa T. et al., 1996). Eleutheroside B inhibits inflammatory COX and diterpene molecules (pinoresinol, sesamin, etc) have the equal activity to the above (Bull K. H. Pharma. Sci. vol. 18, p 43, 1990). As steroid hormone inhibits PLA2 (phospholipase A2), steroids such as β-sitosterol has the same activity so that they prevent arachidonic acid from being separated from phospholipids of cell membrane (Korean Patent Publication No. 2000-9820). Based on the disclosed pharmacological actions of Acanthopanax senticosus as explained hereinbefore, the studies have been focused on the different uses of Acanthopanax senticosus. Korean Patent Publication No. 2000-9820 describes the treatment of acne and whelk using Acanthopanax senticosus. Korean Patent Publication No. 2000-74868 describes the treatment effect of Acanthopanax senticosus on erectile dysfunction. Korean Patent Publication No. 160402 describes that Acanthopanax senticosus is used as an active ingredient for a composition for anti-stress. And the present inventors previously explained that the extract of Acanthopanax senticosus has the neuronal protective effect in Korean Patent Application No. 2001-17459.

To measure the growth stimulated by the extract of crude drug complex, Sprague-Dawley line male rats (3 weeks of age) were purchased from Dae Han Bio Link Co (Korea) and used for the following experiment. The experimental procedure followed the guideline for animal management of NIH, USA. Equal conditions were given to each group, for example temperature was 20±2° C. and the light was given from 07:00 to 19:00. Food and water were provided by libitum and mice were weighed every day.
The rats were divided into 4 groups, 10 per each group. To the negative control group, saline was orally administered twice a day for 4 days. To the experimental group, 100 mg/kg of the extract of crude drug complex (Examples 1-5 and Table 1) or 100 mg/kg of the extract of each herb medicine (Comparative Examples 1-3 and Table 2) was orally administered likewise. To the positive control group, 20 μg/kg of growth hormone was hypodermically injected. On the 3rd day, tetracycline (10 mg/kg) was injected into the abdominal cavity to deposit on the growth plate. On the 5th day, after 48 hours from the tetracycline injection, the rats were anesthetized with ether and sacrificed. The growth was investigated after tetracycline was deposited on the growth plate by measuring the extended length of tibia, which was determined by measuring the interval between the growth plate and the luminescent line developed by the deposit of tetracycline.
The tibia was separated from the rat sacrificed on the 5th day of experiment and fixed in 4% phosphate-buffered paraformaldehyde for 48 hours, followed by precipitating in 30% sucrose solution and dehydration. The fixed bone tissues were freeze-dried and sagital sections of tibia proximal part was cut by cryocut by 40 μm, resulting in the preparation of tissue samples. The sections were used for the bone growth analysis.
To investigate bone growth, the interval between the growth plate and the luminescent line developed by the deposition of tetracycline was observed under fluorescent microscope (Hansson et al., Calcified Tissue Research, 10(3), 238, 1972,
As a result, the extract of crude drug complex stimulated bone growth. The bone growth rate of the experimental group treated with the extract of crude drug complex (Examples 1-5 and Table 1) was statistically higher than those of the negative control group and the group treated with the single extract of each herb (Comparative Example 1-3 and Table 2) and also higher than that of the positive control group injected with growth hormone. The bone growth rate of the group treated with the single extract of each herb (Comparative Example 1-3 and Table 2) was higher than that of the negative control group but lower than that of the positive control (Table 3 and
Considering the bone growth rate of the negative control treated with saline as 100%, the growth rates of the experimental group treated with the extract of crude drug complex (Examples 1-5 and Table 1), the group treated with the extract of each herb (Comparative Example 1-3 and Table 2) and the positive control were calculated. As a result, the growth rate of the experimental group treated with the extract of crude drug complex (Examples 1-5 and Table 1) was significantly higher than those of the negative control and the group treated with each herb extract (Comparative Example 1-3 and Table 2) and even higher than that of the positive control. In the meantime, the growth rate of the group treated with each herb extract (Comparative Example 1-3 and Table 2) was higher than that of the negative control but not than those of the positive control and the experimental group treated with the extract of crude drug complex (Examples 1-5 and Table 1).
1)Calculation formula = 100 + (growth of experimental group − growth of negative control)/growth of negative control × 100
The following experiment was performed to see if the extract of crude drug complex had acute toxicity in mice.
4 week old SPF (specific pathogens free) ICR line mice were divided into 4 groups (6 mice per group, 3 female and 3 male each). The animals were raised in the animal laboratory at the temperature of 22±3° C. with the humidity of 55±10% under the light condition of 12L/12D. The mice were adapted for about 1 week before experiment. Feed (for mouse and rat, Dyets, USA) and water were sterilized and provided freely.
The extract of crude drug complex prepared in the above example was suspended in 0.5% tween 80 at the concentration of 50 mg/ml, which was orally administered once to mice by different concentrations of 0.04 ml per 20 g of weight (100 mg/kg), 0.2 ml per 20 g of weight (500 mg/kg) and 0.4 ml per 20 g weight (1,000 mg/kg). Side effects or death were observed for 7 days from the administration. Particularly, any symptoms and death were observed 1, 4, 8, and 12 hours later on the first day of administration and at least once in the morning and once in the afternoon from the next day to the 7th day. On the 7th day, the animals were sacrificed and any abnormal signs in the gastrointestinal organs of chest and abdomen were checked with the naked eye during autopsy. Weight changes were recorded every day from the first day of administration to observe weight loss by the extract of crude drug complex.
The results showed that the test samples did not cause any specific clinical symptoms, weight change, or death in mice. No change was observed in hematological tests, biochemical tests of blood, and autopsy.
Therefore, the extract of crude drug complex used in this experiment was evaluated to be a safe substance since it did not cause any toxic change in mice up to the level of 1,000 mg/kg and its estimated LD50 value was much greater than 1,000 mg/kg in mice.
