Embodiment one:
1. the preparation of laboratory animal grouping administration and medicine
1.1 the preparation of medicine
1.1.1 Leptoradix Ginseng's superfine powder alcohol extract (Leptoradix Ginseng's osteoporosis effective ingredient part group)
Extracting method by the present invention's 1. Leptoradix Ginseng's osteoporosis effective ingredient part groups extracts: get the Leptoradix Ginseng, pulverize, carry out micronization with the Baily pulverizing mill, add 15 times of 70% soak with ethanol 24 hours, heating and refluxing extraction 2 times is filtered, and keeps filtrate.Filtering residue adds 40% soak with ethanol 24 hours again, and heating and refluxing extraction 1 time is filtered, and keeps filtrate, merges 3 times filtrate, reclaims ethanol, be concentrated into 100% (1g crude drug/ml) and 33% two kind of concentration.Detect middle dosage medicinal liquid (1g crude drug/ml) contain ginsenoside Rg1 6.63 ± 0.26mg/g crude drug, ginsenoside Rb1 32.62 ± 2.4mg/g crude drug, ginsenoside Re 40.85 ± 1.9mg/g crude drug through the HPLC method.
1.1.2 livial: be the tibolone sheet, Nanjing Ou Jianong produces company limited production, specification: 2.5mg/ sheet, lot number: LH-0502-10.
1.2 laboratory animal and raising condition
40 of the adult female unpregnancy SD rats of SPF level, body weight 271.67 ± 25.63g is provided by Guangdong Province's Experimental Animal Center, and Guangdong Province's laboratory animal certification of fitness numbering: word 2006A015 checks and affirm in Guangdong.The raising condition: raise indoor temperature and keep 24 ℃~28 ℃, humidity is 50%~60%, special chamber sub-cage rearing, two in every cage, the next day change bedding and padding, freely take the photograph water, ingest (standard feed that the court's animal center provides) weighs once weekly.
1.3 experimental design and grouping
All the other respectively organize rat with 3% pentobarbital sodium sterile solution 0.13ml100g except that sham operated rats during the removal ovary experiment
-1The BW intraperitoneal injection of anesthesia is sewed up after the aseptic condition hypogastric region excision bilateral ovaries, and the sham operated rats rat is only cut the flesh layer and enters the abdominal cavity and seek out and do not excise behind the ovary and the Hui Na abdominal cavity.Observe wound healing situation and conventional the raising after the operation, begin to do to irritate stomach prevention administration behind the observation 2d.32 rats are divided into 4 groups at random, are respectively every group each 8 of dosage group in sham operated rats, ovariectomized group, livial, the Leptoradix Ginseng's superfine powder alcohol extract, low dose group.2d behind the removal ovary, the positive control drug livial is pressed 0.25mgkg
-1Bwd
-1, Leptoradix Ginseng's superfine powder alcohol extract low dose group is that (100% is that 1g crude drug/ml) add the two volumes distilled water diluting becomes 33% medicinal liquid to middle dosage.Sham operated rats and ovariectomized group give the equivalent distilled water every day and irritate stomach, continuously 90d.
It is as follows that respectively organize the gastric infusion situation every day:
All rats kill preceding 13,14 days subcutaneous injection 25mg.kg
-1Quadracycline each once, in kill preceding 3,4 two days subcutaneous injection calcein 5mg.kg-1 each once, two fluorescent labelinies interval 10 days.Body weight of weighing weekly, the feeding of freely drinking water.After experiment finishes, with 3% pentobarbital sodium (1.5ml.kg
-1) right ventricle executions (to reduce erythrocyte in the bone marrow, get rid of interference, make osteocomma be easier to observation analysis) of thoroughly drawing blood behind the row intraperitoneal injection of anesthesia.Detect index: right side tibia epimere is made the undecalcified bone slice, the stage casing bone is made undecalcified bone abrasive disc, carries out osseous tissue morphometry parameter detecting; Get back bone calcium, phosphorus and the bone hydroxyproline content surveyed of right ulna hydrochloric acid digestion, get right femur and the 5th lumbar vertebra and measure its bone weight, bone density respectively, with this evaluation experimental rat bone composition, bone quantitative changeization; Taking by weighing weight in wet base calculating uterus, uterus index in addition changes substantially to observe the uterus.
2 assay methods
2.1 the mensuration of rat internal organs weight
Weight such as uterus and right femur (weight in wet base) adopts weight method, calculates uterus/weight ratio, femur/weight ratio.
2.2 the assay method of bone calcium, phosphorus and hydroxyproline content
After right ulna precision weighed, 80 ℃ of baking 72h were to constant weight, and precision is weighed and record once more.Subsequently every part of bone specimen is placed 10ml ampere bottle to add 6mol/L HCL 5ml, alcohol blast burner is burnt and is taken out filtration after bottleneck seals back 108 ℃ of baking box constant temperature digestion 24h.Filtrate is divided into two parts, and a with the content of 1:200 dilution back with elements such as ICP instrument mensuration Ca, P, establishing criteria product content and diluted sample multiple calculate the content of elements such as Ca, P again; Another part filtrate, femur dilutes with 1:10, behind accent pH value to 7.0~7.4, measures kit method with UV-752 type ultraviolet spectrophotometer working sample absorbance according to hydroxyproline (hyp), calculates hydroxyproline content in the bone according to formula.
2.3 osseous tissue morphometry method
Non-decalcification bone slice is made in tibia epimere dehydration plastic embedding, and thickness is 4 μ m and 9 μ m, and the transparent back of dimethylbenzene resin mounting is measured the dynamic and static morphology meterological of spongy bone parameter respectively with image analyzer.Static parameter comprises bone trabecula percentage rate (%Tb.Ar), bone trabecula thickness (Tb.Th), bone trabecula number (Tb.N), bone trabecula separating degree (Tb.Sp), the bone formation parameter comprises fluorescent perimeter percentage rate (%L.Pm) in the dynamic parameter, mineralising deposition (MAR), bone formation rate (BFR/BS), bone formation rate (BFR/BV), bone formation rate (BFR/BV); By dynamic parameter, can understand the amount and the speed of bone surface mineralising, and explain the reason that static parameter changes.Middle tibia dehydration plastic embedding, make non-decalcification bone abrasive disc, thickness is 40 μ m, the transparent back of dimethylbenzene resin mounting, measure cortical bone morphology meterological parameter such as cortical bone area (Ct.Ar) with image analyzer, cortical bone area percentage (%Ct.Ar), medullary cavity area percentage (%Ma.Ar).
2.4 the mensuration of bone density
Right femur of the U.S. DEXA of GE-Lunar company borne densitometers experiments of measuring isolated rat and the 5th lumbar spine bmd.
2.5 statistical analysis
Experimental data all uses x ± S to represent, adopts SPSS14.0 software.Relatively adopt one factor analysis of variance (ANOVA) between the group of normal distribution data, variance adopts the LSD check together; Heterogeneity of variance then adopts Tamhane ' s T2 check; After skewness distributes and then uses the Kruskal-Wallis rank test, further use Conover ' s t check difference between group more in twos again.
