  • Although an adequete intake of calcium (Ca) is recommended for the treatment and prevention of osteoporosis, the intake of Ca should be restricted because of its low rate of intestinal absorption. The purpose of this experiment was to identity the effect of the combined administration of Aquamin F (AQF) (a calcium agent) and lactic acid bacteria (LAB) on osteoporosis. Thirty ovariectomized (OVX) rats and six control rats were assigned to the following six groups, with six animals per group: sham Ca-deficient diet (Ca-D), OVX, LAB, AQF, and LAB-AQF. During the experiment, the body weight was measured; and after the experiment was completed, the serum biochemical analysis, the alkaline phosphatase, calcium, and inorganic phosphorus leves were measured. The tissue of the femur was stained and then scanned via CT. The body weight of the OVX group increased more significantly than that of the control group. The results of the bone mineral content (BMC), Bone mineral density (BMD), serum biochemical analysis and histological test on the femur epiphysis showed no difference between the OVX group and the LAB group, whereas the results of the AQF group were more significant than those of the OVX group. In particular, the LAB+AQF group showed more significant increases in the aforementioned results than the AQF group. This experiment showed that the combined administration of AQF and LAB in ovariectomized rats more significantly increased bone density than did a single administration of either AQF or LAB.

  • Calcium is an essential nutrient for living organisms, with key structural and signaling roles. Its deficiency in plants can result in poor biotic and abiotic stress tolerance as well as reduced crop quality and yield. Calcium deficiency in humans causes various diseases such as osteoporosis and rickets. Biofortification of calcium in various food crops has been suggested as an economic and environmentally advantageous method to enhance human intake of calcium. Recent efforts to increase the levels of calcium in food crops have used calcium/proton antiporters ($CAXs$) and modified one to increase calcium transport into vacuoles through genetic engineering. It has been reported that overall calcium content of transgenic plants has been increased in their edible portions with some adverse effects. In conclusion, biofortification of calcium will add more value in crops as well as will be beneficial for animal and human. Therefore, more fundamental studies on the mechanisms of calcium ion storage and transporting are essential for more effective calcium biofortification.

  • This study was done to evaluate the effect of dietary calcium level (a diet which met 100% or twice the calcium level in AIN-76 diet) on preventing bone loss in ovariectomized rats. Forty Sprauge-Dawley female rats(body weight 200$\pm$5g)were divided into two groups. One group were ovariecotomized (Ovx) while the others received sham operation(Sham). Thereafter, each rat group was further divided into normal calcium diet(0.52%) and high calcium diet(1.04%) subgroups. All rats were fed on experimental diet and deionized water ad libitum for 8 weeks. The total body, spine and femur bone mineral densities and bone mineral contents were measured by Dual Energy X-ray Absorptiometry, Eight weeks following operation, ovariectomized rats fed a high calcium diet had a significantly higher total bone mineral content, total bone calcium content, spine bone mineral density, spine bone mineral content and femur bone mineral content than ovariectomized rats fed control calcium diet. The correlation between dietary calcium intake level and spine bone mineral density were positive, but there was no correlation between dietary calcium intake and femur bone mineral density. The findings from the present study demonstrated that bone loss due to ovarian hormonal deficiency can be partially prevented by a high calcium diet. Futhermore, these findings support the strategy of the use of a high calcium diet in the prevention of estrogen depleted bone loss(postmenopausal osteoporosis)

  • Bones are important parts in sustaining the shape of the body, but they are also metabolic organs which undergo bone remodeling by constant bone resorption and formation. Osteoporosis, the typical metabolic bone disease, is characterized by a reduction in bone mineral density (BMD). Women more than men are at risk fir osteoporosis-related fractures, especially in the lumbar spine, wrist, and hip region. Risk of fracture depends on one's BMD, which open determined by the peak bone mass value achieved at skeletal maturity and followed by subsequent age-and menopause-related bone loss. Genetic and environmental factors are known to play a key role in bone metabolism and diet is considered as one of the important environmental factors. The purpose of the present study was to assess the status of BMD and bone mineral content(BMC) to clarify the relationships between dietary intakes and the risk of osteoporosis in adult women in Taegu. Subjects were 130 healthy females in between 20 and 69 years of age. BMD and BMC of the lumbar spine(venebrae L2-4) of the subjects were measured by dual energy X-ray absorptiometry. The average age of the subjects was 47.4${\pm}$11.7 years old, the average weight was 57.2${\pm}$8.4kg, the average age of menarche was 16.6${\pm}$1.9 years old and the average age of menopause was 48.4${\pm}$5.3 years old. The nutrient intakes of the subjects measured by the convenient method were generally lower than the level of RDA. The result of nutrient intake assessed has shown that the average energy intake was 1701${\pm}$316kca1 which is 85.1% of the RDA and the average calcium intake was 485.4${\pm}$172.3mg which is 69.3% of the RDA. The intakes of protein, vitamin A, vitamin B$_1$, niacin were greater than the RDA, whereas the remaining nutrient intakes were lower than the RDA. The average BMD of the subjects was shown to be 1.06${\pm}$1.09g/$\textrm{cm}^2$. The highest BMD of 1.24${\pm}$0.14g/$\textrm{cm}^2$ was noticed in the subjects of 30s compared to 20s, 40s, 50s, 60s. The BMD values were compared by the relative body weight(R3W) of the menopause subjects, and it was found that the underweight group had significant lower BMB while the rest of the groups did not have any differences in BMD. The most strongly correlated nutrient with BMD among the menopause subjects appeared to be calcium. The women whose Ca intakes were higher than 500mg showed the significantly higher BMD than those with Ca intakes lower than 500mg. This study suggests that the most effective way to prevent osteoporosis and to reduce the incidences of fractures seems to be minimizing bone loss through the adequate intake of calcium as well as avoiding underweight, especially in menopausal women.

  • The effect of herbal medicine on osteoporosis was studied using ovariectomized rats as an animal model of Type I osteoporosis and SAM P6 mice as that of Type II. Each traditiona l boiling water extract of Achyranthis Radix, Psoraleae Radix, Rehmanniae Radix Preparat, Corni Fructus and Mycelia of Ganoderma, and systemic water fraction of Astragali Radix was given 5g(dried herbal weight)/kg/day p.o. for 30 days in each group of ovariectomized rats, SAM R1 and SAM P6. The extract of Cervi parvum Cornu was given for 14 days only. One ml of blood was taken by tail vein at day 0, 7, 14, 21 and 30 days after administration of the extract. Plasma levels of alkaline phosphatase, calcium, creatinine,inorganic phosphate, blood urea nitrogen, cortisol, total $T_3\;and\;total\;T_4$ were measured. In ovariectomized rats, administration of Achyranthis Radix or Corni Fructus decreased in alkaline phosphatase and that of Achyranthis Radix or Psoraleae Radix decreased in calcium comparing to the control (p<0.05). The administration of Psoralese Radix decreased in calcium and increased in urea comparing to day o(P<0.05)(Table I). There were not much changes in plasma calcium, inorganic phosphate, and alkaline phosphatase concentrations after uptake of these herbal medicine used in SAM P6(Table III). However, administration of Astragali Radix altered plasma inorganic phosphate and creatinine levels in SAM R1(p<0.01)(Table UU). The administration of Corni Fructus or Psoralease Radix induced the changes in plasma concentrations of cortisol, total $T_3$ and total $T_4$ in Type I(p<0.05) (Table IV). The uptake of Cervi parvum Cornu increased in total $T_3$ concentration and that of Mycelia of Ganodtragali Radix in SAM P6. However, the uptake of Mycelia of Ganoderma induced changes in cortisol and $T_4$ concentrations in SAM R1(p<0.05). Thus, there were significant differences in responses of herbal medicine in different types of osteoporosis.

  • Background: Examination of the effects of deer antler, old antler, and antler glue on postmenopausal osteoporosis in an ovariectomized Sprague-Dawley rat model. Methods: The study involved 7 experimental groups; SHAM (sham-operated rats), OVX (ovariectomized rats), E2 (ovariectomized rats with estradiol $10{\mu}g/kg$ daily, orally), DA (ovariectomized rats with deer antler extract 5.83 mg/kg), OA (ovariectomized rats with old antler extract 3.8 mg/kg), low-AG (ovariectomized rats with low dose of antler glue powder 12.5 mg/kg), high-AG (ovariectomized rats with high dose of antler glue powder 37.5 mg/kg). After 6 weeks of treatment, body weight, blood calcium, phosphorus, estradiol, liver [alkaline phosphatase (ALP), aspartate transaminase (AST), alanine transaminase (ALT)] and kidney [blood urea nitrogen (BUN)/creatinine ratio] function, and femoral bone mineral density (BMD) were measured. Results: The body weights of DA, OA, low-AG, and high-AG groups did not significantly differ from OVX group. Blood estradiol levels were significantly increased in the DA, low-AG, and high-AG groups compared to the OVX group. Blood calcium, phosphorus, ALP, AST, and ALT levels and BUN/creatinine ratio did not show significant changes in the DA, OA, low-AG, and high-AG groups. BMDs of the femur, and femoral head and neck were significantly increased in the low-AG group. In the OA group, the BMD of the femoral head and neck was significantly increased. Conclusion: Treatment with deer antler, or antler glue for 6 weeks was effective for increasing estradiol and femoral BMD in ovariectomized rats, suggesting that this may be of therapeutic benefit for osteoporosis.

  • Objective & Method: The purpose of this study is to investigate the effects of herbal-acupuncture with Corni Fructus extract (CF-HA) at Eumgok(KI10) on osteoporosis in ovariectomized (OVX) ddy mice. I carried out several experimental items to analyze the changes in body weight, uterine weight, uterus index, tibial length, the ash bone weight, tibial BMD, the levels of serum ALP, osteocalcin, Ca, P and the levels of tibial Ca, P, Ca/P ratio, and we performed histological and histomorphological analysis as well. Result: 1. CF-HA at Eumgok(KI10) significantly did not increase the level of bone mineral density in overiectomized mice. 2. CF-HA at Eumgok(KI10) significantly decreased the level of serum phosphorus in ovariectomized mice and sinificantly increased the level of serum calcium in ovariectomized mice. 3. CF-HA at Eumgok(KI10) significantly increased the levels of tibial calcium and phosphorus in ovariectomized mice. 4. CF-HA at Eumgok(KI10) significantly decreased the number of tibial osteoclast like cell in ovariectomized mice. 5. In the histomorphometric analysis of tibia, GPL(growth plate length) was significantly decreased by CF-HA at Eumgok(KI10) in ovariectomized mice. Conclusions: These results suggest that CF-HA at Eumgok(KI10) may have useful therapy effects on osteoporosis in ovariectomized mice.

  • Objectives Osteoporosis is a common disease in adults with prevalence rate of more than 40%, and occurs more to female than to male. The purpose of this study is to identify the effect of Bia-hwan ($F{\acute{e}}i{\acute{e}}r$-$w{\acute{a}}n$) on the osteoporosis of ovariectomized rats. Methods 24 female rats were randomly assigned to a SHAM group, a control group, and a BAH group. Ovaries of the control group and the BAH group were extracted. After than, general animal feed were given to the SHAM group and the control group, animal feed contained BAH were given to the BAH group through mouths of them. After 8 weeks, rats were sacrificed and their weight, calcium, phosphorus, estradiol, total-cholesterol, triglyceride, ALP, albumin, AST, ALT, the weight of femur and tibia ash per body ratio, both area and thickness of trabecular bone, the area of osteoblast and the number of osteoclast were measured. Results The level of calcium, phosphorus, AST in the serum of the BAH group increased significantly compared to the control group. There was no significant difference between the control group and the BAH group in the level of estradiol, total-cholesterol, triglyceride, ALP, albumin, and ALT in the serum. There was no significant difference between the control group and the BAH group in the weight of femur and tibia ash per body ratio. The thickness of trabecular of the BAH group increased significantly compared to the control group, but there was no significant difference in the trabecular area. The area of osteoblast and the number of osteoclast of the BAH group decreased significantly compared to the control group. Conclusions From the results of the above study, oral intake of BAH can inhibit the decrease of calcium, phosphorus in blood and prevent the thinning process of the trabecular by suppressing activation of osteoclast. Thus, BAH may have effects on the treatment and prevention of osteoporosis.
