Effective Components of Zhuanggu Zhitong Prescription and its Influence on Hormones Related to Bone Metabolism in Female Rats
Objective:To find the effective components of Zhuanggu Zhitong prescription
investigate its influence on hormones related to bone metabolism and to explore its possible mechanism.Method:One hundred and fifty SD female rats weighing around 250 g(three months old) were randomly divided into model group(ovariectomized
OVX)
sham operation group
control group
ethanol extraction group A
ethanol extraction group B
petroleum ether extraction A position group
water extraction site group A
water extraction site group B
Fraction extracted with ethyl acetate group A
Zhuanggu Zhitong prescription group
a total of 10 groups(n=15 each).Five days after stitches of the operation of taking out ovaries
different treatments were carried out for 13 weeks.Blood and bone samples were collected for investigations on bone mineral density
bone biomechanics
pathology and other aspects to evaluate efficacy
and serum estradiol(E2)
bone gla protein(BGP)
parathyroid hormone(PTH)
calcitionin(CT)
to explore the effective mechanism.Result:Compared with model group
Zhuanggu Zhitong prescription group A part of ethanol extraction
water extraction B parts
petroleum ether A site could significantly increase the levels of OVX rats femur
lumbar spine bone mineral density(P<0.05
P<0.01);could increase osteoporosis in ovariectomized rat tibia model the maximum stress and maximum bending strength(P<0.05
P<0.01);could significantly increase the average trabecular bone density of the femoral head
the difference was significant(P<0.01)
with no significant difference to Zhuanggu Zhitong prescription group.Compared to OVX model group
Zhuanggu Zhitong prescription could only significantly increase in serum E2
prevent uterine atrophy caused by insufficient estrogen(P<0.05);Zhuanggu Zhitong prescription could significantly decrease serum BGP
PTH
CT for the castrated rats(P<0.05).Conclusion:The ethanol extract parts of group A
water extraction site group B
petroleum ether extract A position group site are the effective components of Zhuanggu Zhitong prescription for treating osteoporosis.Zhuanggu Zhitong prescription can increase the serum level of E2
and decrease the levels of BGP
PTH
CT
directly or indirectly regulate the body’s bone metabolism and cytokines
to improve hormone metabolism
the molecular structure of bone matrix and to strengthen the mechanical properties of bone
