Osteoporosis (OP) is a systemic metabolic disease of bone characterized by low bone mass and microstructural destruction of bone tissue, leading to increased bone fragility and susceptibility to fracture, common in the elderly, but can occur at all ages. The Chinese white paper for preventing and treating osteoporosis indicates that at least 6944 million people in China have osteoporosis, 2.1 million people have low bone mass and have osteoporosis risk, 70-80% of middle-aged and old people fracture is caused by osteoporosis, wherein about 181 million people have new vertebral fracture every year, and 23 million cases of hip fracture occur. Researches show that the incidence rate of osteoporosis is 54-71% in 55-65 years old; the prevalence rate for elderly is 60.72% for men and 90.47% for women. With the advent of aging society, osteoporosis has become a high-incidence disease threatening the health of middle-aged and elderly people.
Bone density refers to the bone mineral content per unit volume and is an important marker of bone quality. The more mineral deposits, the greater the bone density and the firmer the bone. Bone density is the main standard for diagnosing osteoporosis, and the world health organization defines that osteoporosis is the condition that the bone density of an adult female is lower than the average value by 2.5 standard deviations.

The sample contained 11.3% calcium. 70 female adult rats (cleaning grade SD rats) 250-288 g are selected in the experiment. The temperature of the breeding room is 20-25 ℃, and the relative humidity is 40-70%.
Rats are anesthetized by intraperitoneal injection of 30 mg/kg-bw sodium pentobarbital solution, hairs at the positions of dorsal costal ridges are removed, iodine tincture and alcohol are respectively used for sterilization, bilateral ovaries are cut off, and another group of animals are taken for the same operation without cutting the bilateral ovaries and are used as a sham operation control group. 5 days after ovariectomy of the rats, vaginal smear examination was performed to eliminate the ovariectomized rats.
Dose design: according to the requirements of experimental items, three dosage groups of low, medium and high are set, namely 0.32, 0.63 and 1.89g/kg · bw, which are equivalent to 5 times, 10 times and 30 times of the recommended dosage of a human body. The rats after the operation are randomly divided into a model control group, a positive control group (1.0 mg/kg-bw estradiol), a calcium carbonate control group (the calcium level is the same as the high-dose calcium level) and a low, medium and high dose group according to the weight, wherein each group comprises 10 rats, and 10 sham-operated rats are taken as the sham-operated control group.
Preparing a test substance: samples 0.32, 0.63 and 1.89g are respectively taken, deionized water is added to 10mL, and test solutions of low, medium and high dosage groups are uniformly prepared; 534mg of calcium carbonate is taken, deionized water is added to 10mL, and the calcium carbonate is uniformly mixed to prepare a calcium carbonate control group test solution; deionized water was given to both the sham-operated group and the model control group. Each group of drinking water was deionized water.
Subject administration mode: the samples were administered by gavage with a gavage volume of 10mL/kg body weight. Gavage was performed once daily, each group of doses was designed to be given for 12 weeks, and the rats were given deionized water throughout the duration of the experiment, and body weights were recorded weekly, during which time the experimental rat feed formulations were as shown in table 1:

TABLE 2 Effect of samples on rat body weight
Figure GDA0003364587750000072
Figure GDA0003364587750000081
Note: indicates that the difference between each group in the same column and the comparison group of the model control group is significant, and P <0.05
As can be seen from Table 2, the average body weight and weight gain of the control group after four weeks are significantly higher than those of the control group after the false operation, which suggests that abnormal increase of body weight caused by hormone level disorder due to estrogen reduction of the animals after the operation may occur, indicating that the model is established. The average body weight in the middle and four weeks, the average body weight in the later four weeks and the weight gain of the positive control group are all obviously lower than those of the castration model control group. Compared with the model control group, the initial weight, the average weight per four weeks and the weight gain of each dose group have no obvious difference (P > 0.05). Compared with the calcium carbonate control group, the high-dose group has no significant difference in initial body weight, average body weight per four weeks and weight gain (P > 0.05).
Measuring the bone density of the femur: the rats were dissected, the left femur was dissected and baked to constant weight. The bone density of the midpoint of the femur and the distal end of the femur of a rat are measured by using a discovery-wi type bone densitometer, and the bone calcium content is measured by using an atomic absorption method, wherein the results are shown in table 3:
TABLE 3 Effect of samples on rat femoral weight, bone calcium and femoral bone Density
Figure GDA0003364587750000082
Note: indicates that the difference between each group in the same column and the model control group compared with each group is significant (P <0.05)
