The hormonal control of the hypothalamo-pituitary-ovary(ocular graft)axis was investigated in the rabbits.Autotransplantation of the ovary to theanterior chamber of the eye was performed immediately after bilateral ovariec-tomy.The FSH,LH,cAMP and Progesterone content in the blood of the controlrabbits and the rabbits with ocular ovarian grafts were determined by RIA andcompetitive protein-binding assay method.The experiments disclosed thatafter exogenous intravenous administration of 5 μg/kg of GnRH,there was a gra-dual increment in both FSH and LH content at 30,60 and 240 mins intervals,with basically similar pattern.When the graft-bearing animals were mated withmales,the FSH,LH and cAMP content in the blood at 30,60,120 and 240 minsintervals also showed conspicuous increase of similar magnitude in both the con-trol and the experimental,groups of animals.The characteristic hemorrhagic spots on the surface of the graft,designatedas the ovulatory response,might be initiated by mating,copper acetateHCG orGnRH.The blood Progesterone content measured on the second,fourth andsixth day after the ovulatory response increased 5-6 times above normal.Further-more,the ovulatory response could be suppressed by the administration of theantifertility solution no.1 or 18-megestrol.Taken all these experimental datatogether,it is believed that the integrity of the hypothalamo-pituitary-ovary(ocular)axis is essentially normal as compared with that of the normal.The transparent cornea(‘window’)furnishes a very convenient means of carry-ing out direct and long-term observations,particularly useful for screening an-tifertility drugs and in the delineation of the relations of the different componentsof the axis.

本文研究了家兔下丘脑—垂体—(眼前房)卵巢轴的激素调节特点。实验用成年雌兔,在摘除两侧卵巢后立即将一片卵巢组织移植于眼前房。分别用放射免疫法及竞争性蛋白结合法测定正常对照组兔与移植组兔静脉血中FSH、LH、cAMP 及孕酮含量。结果表明,移植兔与正常兔一样,静脉注射GnRH(5微克/公斤)后30、60及240分钟,血中FSH 与LH 含量有逐渐增加趋势并显著高于基础水平。与雄兔交配后30、60、120及240分钟内,血中FSH、LH 及cAMP 的含量也明显上升,两组动物三项指标变化的幅度相似。交配,静脉注射醋酸铜、HCG 或GnRH,均可使移植卵巢发生典型点状出血,称为排卵反应。在出现排卵反应后的第二、第四与第六天,血中孕酮含量较给药前增加5—6倍。上述排卵反应,在不同程度上可被避孕一号与复方18甲基炔诺酮所抑制。证明了移植动物的下丘脑—垂体—(眼前房)卵巢轴的激素调节与正常物动相比,是基本一致的。通过透明的角膜(橱窗)可长期直接观察排卵进程的变化,为研究下丘脑—垂体—卵巢轴活动规律与筛选抗排卵药物,提供简便的慢性动物模型。

The effect of tyrosine on the stero(?)dogenesis and cAMP accumulation ot the granulosacells and theca tissues in the rat was studied by the incubation method.To obtain thegranulosa cell suspensions and theca tissues,the preovulatory follicles of rats were manuallyisolated 42 hours after a single injection(SC)of HCG.After isolation,granulosa cellsuspensions were made and co-cultured with the theca tissues for 4 hours in KRBGAL buf-fer.Then,the progesterone and estrogen contents in the incubates were ascertained...

The effect of tyrosine on the stero(?)dogenesis and cAMP accumulation ot the granulosacells and theca tissues in the rat was studied by the incubation method.To obtain thegranulosa cell suspensions and theca tissues,the preovulatory follicles of rats were manuallyisolated 42 hours after a single injection(SC)of HCG.After isolation,granulosa cellsuspensions were made and co-cultured with the theca tissues for 4 hours in KRBGAL buf-fer.Then,the progesterone and estrogen contents in the incubates were ascertained byRIA,while the cAMP accumulation in them was determined by the competitive proteinbinding assay.These preliminary experiments indicated that tyrosine,when added tothe incubation media containing HCG,conspicuously antagonized the effect of HCG on pro-gesterone,estrogens and cAMP production,with the progesterone and cAMP contents inthe incubates decreased from 115.4 ± 14.5 ng/ml to 56.6 ± 4.6 ng/ml and from 24.8± 1.4 pmol/ml to 13.8 ± 0.8 pmol/ml,respectively,while that of the estrogens increasedfrom 3.29 ± 0.40 ng/ml to 20.47 ± 2.10 ng/ml.It may therefore be postulated that tyrosine may block the action of HCG at the ovarianlevel.The mechanism of the antagonistic effect of the tyrosine molecule remains to beclarified.

给雌性大鼠注射20IU/只HCG 后42小时,分离出排卵前卵泡,将卵泡颗粒细胞和内膜组织混合培养,45分钟后测cAMP 含量,4小时后测定孕酮和雌激素的含量。实验表明,酪氨酸可抑制HCG 所致的cAMP 和孕酮的生成,HCG 组孕酮含量为115.4±14.5毫微克/毫升,加入酪氨酸后孕酮含量为56.6±4.6毫微克/毫升(P<0.01);cAMP 含量则从24.8±1.4微微克分子/毫升降至13.8±0.8微微克分子/毫升。与上述变化相反,酪氨酸对雌激素的生成似有促进作用。本工作提示酪氨酸可在卵巢水平阻断HCG 的作用。

A 1 cm segment of oviductal isthmus was taken,1 to 4 cm from the junctura,from ananesthetized rabbit.The sample was soaked in a 38℃ double glass chamber bath,whichcontained Krebs' solution bubbled with a mixture of 9.5% O_2 and 5% CO_2.The lower andof the tissue was attached to a fixed hook at the base of the bath and the top end was con-nected to a strain gauge.The muscular contraction of oviductal isthmuses from five groupsof animals in different hormonal states(estrous rabbit,ovulated rabbit,ovariectomized rab-bit,immature rabbit and immature rabbit with EB〔Estradiol Benzoate〕was recorded con-tinuously for 1-2 hours,using the polygraph.The optimal condition of the dose-response relationship was studied.The isthmic moti-lity in all five groups showed a common tendency:In the first 30-minute period,there occurredan “adaptive phase”in which the tension of the smooth muscle increased progressively;inthe following 30-50 minute peroid there was a“steady phase”,during which the tension,frequency and amplitude of the spontaneous single contractions became relatively steady.Beyond this period,the isthmic contractility varied significantly according to the differenthormonal states of the rabbits.Firstly,the contractility pattern of the estrous and ovulatedrabbits displayed a series of burst-like contractions,but no such phenomena could be observedin the immature or ovariectomized rabbits.Secondly,the order of the contraction tensionin the five groups was:ovulated rabbit group>estrous rabbit group>immature rabbitwith EBgroup>ovariectomized rabbit group>immature rabbit group.Thirdly,the rate oftension increase(RTI)revealed that the ovulated rabbit group showed a rapid change inRTI,sustained for about 30 minutes.However,the other four groups had a dramatic increascin RTI in the first 10 minutes,but afterwards the change became less rapid.It is suggested that the variation in the criteria mentioned above is correlated to the ova-rian hormonal level,which might influence the protein synthesis in the smooth muscle,thesize of the fibers,the glycogen content and the sensitivity of the muscle NE(Norepinephrine)receptor.In addition,a repeatable-dose response result could be obtained by this in vitro methodduring the“steady phase”in the determination of the sensitivity response of the oviduc-tal isthmus to NE.

本实验应用肌肉收缩机械—电换能器和生理记录仪观察在不同激素状态下兔离体输卵管峡部平滑肌自发收缩张力、张力变化速度以及收缩波型的变化并进行比较研究。通过1—2小时连续记录,摸索测定兔输卵管平滑肌对去甲肾上腺素敏感性反应的最适条件。结果表明:1.兔离体输卵管峡部平滑肌活动与激素状态有密切关系,峡部在不同激素背景下的自发收缩张力、张力变化速度以及收缩波型均有明显差异。产生差异的原因。推测可能是卵巢激素水平的高低影响输卵管平滑肌蛋白质的合成、肌纤维醣元含量以及肌肉内去甲肾上腺素含量或受体敏感性等;2.在离体条件下,五组不同激素状态的兔输卵管峡部平滑肌无论是新鲜材料还是在4℃Krebs 液保存2—6小时的材料都有一个“平稳期”,选择此期作为观察输卵管峡部平滑肌对NE 的敏感性反应,可获得重复性较高的剂量-反应曲线。
