In the present study, 7α-methyl-10β, 17β-diacetoxy-A4-estren-3-one were shown to be able to terminate pregnancy following subcutaneous administration on the 7 th and 8 th days of pregnancy in rats, and on the 4 th and 5 th days in mice. The ED_(50) of 7a-methyl-10β, 17β-diacetoxy-△~4-estren-3-one for the interruption of early pregnancy in mice was 1.6 mg/kg. Under similar experimental condition the ED_(50) of 7β-methyl-10β, 17β-diacetoxy-△~4-estren-3-one was found to be 5.5 mg/kg. After administration of effective...

In the present study, 7α-methyl-10β, 17β-diacetoxy-A4-estren-3-one were shown to be able to terminate pregnancy following subcutaneous administration on the 7 th and 8 th days of pregnancy in rats, and on the 4 th and 5 th days in mice. The ED_(50) of 7a-methyl-10β, 17β-diacetoxy-△~4-estren-3-one for the interruption of early pregnancy in mice was 1.6 mg/kg. Under similar experimental condition the ED_(50) of 7β-methyl-10β, 17β-diacetoxy-△~4-estren-3-one was found to be 5.5 mg/kg. After administration of effective dose of 7α-methyl-10β, 17β-diacetoxy-△~4-estren3-one to early pregnant rats, the peripheral plasma progesterone level was decreased markedly. At the concentration of 10 μg/ml, 7α-methyl-10β, 17β-diacetoxy-△~4-stren-3-one showed significant inhibiting action on progesterone biosynthesis in isolated pregnant rat ovary. Relative binding affinity (RBA) of 7a-methyl-lOft, 17β-diacetoxy-△~4-estren-3-one for rabbit uterine estrogen receptor was found to be 10.8 and that of 7β-methyl-10β, 17β-diacetoxy-△~4-estren-3-one to be 1.5. However, 7△-and 7β-methyl-10β, 17β-diacetoxy-△~4-estren-3-one were of poor affinity for progesterone binding sites. Result obtained from the uterine growth test in immature mice showed that the estrogen and antiestrogen activity of 7β-methyl-10β, 17β-diacetoxy-△~4-estren-3-one was weaker than that of 7α-methyl-10β, 17β-diacetoxy△~4-estren-3-one.

7α-和7β-甲基-10β,17β-二乙酰氧基-△~4-雌甾烯-3酮(简称7α-和7β-甲-乙氧雌酮)对小鼠抗早孕ED_(50)分别为1.6和5.5 mg/kg。7α-甲-乙氧雌酮在大鼠也有抗早孕作用并使血浆孕酮浓度降低,应用10 μg/ml浓度能抑制离体妊娠大鼠卵巢孕酮合成。7α-和7β-甲-乙氧雌酮与兔子宫胞浆雌二醇受体的相对结合亲和力(RBA)分别为10.8和1.5,与孕酮受体的RBA均<1.7α-和7β-甲-乙氧雌酮都有较弱的雌激素和抗雌激素活性。

The membrane layer is taken outand washed free of sucrose by centrifugationat 39000×g...

It has been documented that the ovariancell membrane has specific HCG receptors.The isolation and characterization of theovarian cell membrane have been studied. Rat ovaries are homogenized and sonicedunder ice-cold conditions. The homogenatesare centrifuged at 2000×g for 15 min. Aftersucrose density gradient ultracentrifugation(78000×g, 4h), two fractions are collectedfrom layer of 33% and interface between 33%and 37%. The membrane layer is taken outand washed free of sucrose by centrifugationat 39000×g for 1h. The pellets are suspendedin an appropriate: amount of 40 mM Trisbuffer. In comparison with homogenates andsonicates, the activity of 5-nucleotidase ofplasma membrane increases ten times. HCGreceptor binding of the plasma membrane is1750 times as high as the homogenates andsonicates. Preparations are checked by elec-tron microscopy. Nuclei, mitochondria,lysomes, rough microsomes and Golgimembranes are absent from most of thepreparations. The separation at the four sucrose con-centrations (33%, 37%, 41%, 45%) is more effec-tive than at the five sucrose concentrations(33%, 37%, 41%, 45%, 48%). The centrifugespeed (78000×g) is the optimum speed.

作者用匀浆、超声波及蔗糖密度梯度离心法制备了卵巢细胞膜,较单纯匀浆之HCG结合率提高1750倍,四种蔗糖浓度及五种蔗糖浓度之分离效果对比,以前者为宜,离心速度为78000×g时结合率最高,且集中于33%表面层及33%~37%界面层。

A rapid,sensitive,accurate and specific radioreceptor assay(RRA), by using 2000g fractions of homogenates of pseudopregnant rat ovaries as receptor source and radioiodinated human chorionic gonadotropin (125I-HCG ) as labelled ligand , was described for measurement of LH in bovine plasma and serum. USDA-bLH-5 and HCG were used as reference standards. The dose response curve of bLH was parallel to that of HCG. The sensitivities of bLH and HCG were found to be 0.1 ng and 0.03ngper tube respectively. The...

A rapid,sensitive,accurate and specific radioreceptor assay(RRA), by using 2000g fractions of homogenates of pseudopregnant rat ovaries as receptor source and radioiodinated human chorionic gonadotropin (125I-HCG ) as labelled ligand , was described for measurement of LH in bovine plasma and serum. USDA-bLH-5 and HCG were used as reference standards. The dose response curve of bLH was parallel to that of HCG. The sensitivities of bLH and HCG were found to be 0.1 ng and 0.03ngper tube respectively. The criteria of validation such as recoveries of added bLH and HCG to plasma, reproducibility, specificity were examined. The coefficients of variation within a single assay and between assays were 8.89% and 14.69% respectively. When this assay was used to measure the LH contents in unknown bovine plasma samples,it is not necessary to remove the nonspecific interfering factors from the plasma if 10-40μl plasma was used.However,when more than 40μl plasma was used for LH quantitation, the interference of nonspecific factors may occurμ

本试验以假孕大鼠卵巢组织匀浆作 LH/HCG受体建立了 bLH/HCG放射受体分析法(RRA)。bLH和HCG的剂量反应曲线平行,灵敏度分别为0.1ng/管和0.03ng/管。用本方法测定牛血浆LH水平时,不需要对血浆进行处理,供测血浆量可取10-40μl。方法的重复性较好,组内变异系数为8.89%,组间变异系数为14.69%;无LH牛血浆添加bLH和HCG的回收率分别为98.98±11.94%和102.8±5.81%。 研究了无LH牛血浆和BSA对标准曲线的影响。与前人对人血浆的研究结果比较,发现牛血浆和人血浆对RRA的干扰特性不同,推论血浆RRA干扰因子存在着种属特异性。
