The oestrogens in the urine of 13 early pregnant and 6 non-pregnant sows were determined by the method of Brown (1955). For the full course of the pregnancy, the determination of the oestrogens was likewise made from 3 sows at weekly intervals.It was found that the concentration of the oestrogens during the course of pregnancy shows two high levels. The first one appears at 25th to 30th day of pregnancy and the second one begins from 11th week and it reaches the maximum concentration at the time just before the parturition. The earliest diagnosis for pregnancy can be possibly made as indicated by raising in the concentration of oestrogens at the third week of pregnancy. Among them, the oestrone is predominant and the oestradiol and oestriol practically remain unchanged.This finding may be used as an early pregnancy diagnostic index in the sow.

用Brown氏化学方法测定了三头孕猪整个妊娠期间,尿液中的雌酮,雌二醇和雌三醇的排出情况.每周测定一次.同时测定并比较了13头早期妊娠母猪(25~30天)和6头未孕母猪雌性激素的排出量.结果说明:在整个妊娠期间出现二次排出高峰,笫一次在25~30天,第二次开始于交配后第11周,临分娩前达最高峰,均以雌酮为主.而雌二醇、雌三醇的排出量,始终恒定在低水平.本文对孕猪雌性激素的代谢类型、雌二醇、雌三醇的纯洁度以及品种差异等问题分别进行了讨论.并且认为利用孕猪交配后第25-30天尿中雌酮含量作为母猪早期妊娠诊断依据,则本测定方法,确有专一性,可靠性,但鉴于目前的条件,在生产实践中推广应用,尚须研究简化.

The regulation of luteal enzymatic activities, △5-3β-hydroxysteroid dehydrogenase (3β-OH-SDH) and acid phosphatose, by prostaglandin F2α, (PGF2α) and luteinizing hormone (LH) in corpora lutea of the pregnant rats has been investigated by histo-chemical methods. Extensive 3β-OH-SDH activity was shown in the corpora lutea of the pregnant rats (figs. 1 & 2). Termination of pregnancy accompanied by a decrease of 3β-OH-SDH activity was observed when PGF2α was administered on Day 9 of pregnancy at a dose...

The regulation of luteal enzymatic activities, △5-3β-hydroxysteroid dehydrogenase (3β-OH-SDH) and acid phosphatose, by prostaglandin F2α, (PGF2α) and luteinizing hormone (LH) in corpora lutea of the pregnant rats has been investigated by histo-chemical methods. Extensive 3β-OH-SDH activity was shown in the corpora lutea of the pregnant rats (figs. 1 & 2). Termination of pregnancy accompanied by a decrease of 3β-OH-SDH activity was observed when PGF2α was administered on Day 9 of pregnancy at a dose of 500 μg twice daily for three consecutive days (figs. 3, 4 & 9D), A similar decrease in enzymatic activity was noted in hypophysectomised-pregnant rats (hypophysectomy was carried out on Day 9 of pregnancy; fig. 7). Administration of LH (potency: 1200 i.u./mg; 50 μg twice daily for 3 days), on the other hand, not only resulted in the maintenanee of pregnancy in hypophysectomised rats but also restored tie enzymatic activity to an elevated level comparable to that observed in the control rats (figs.9B & 8). Simultaneous administration of PGF2α and LH resulted in partial maintenance of pregnany as evidenced by the presence of viable but somewhat smaller embryos in the uterus (fig. 9C). An antagonism between PGF2α and LH at the ovarian level was, therefore, demonstrated. The assumption of a direct effect of PGF2α on 3β-OH-SDH seems unlikely, since PGF2α has been shown to act also on cholesterol ester synthetase as well as cholesterol esterase in the corpora lutea of rats (Behrman et al, 1971).The luteal cells of mid-pregnacy (Day 12) exhibits almost no detectable acid phosphatase activity (fig. 5). PGF2α treatments, however, produced a rise in enzymatic activity as observed in the corpora lutea during involution or after hypophysectomy (fig. 6). Since acid phosphatase is well documented as one of the important hydrolases in lysosomes and has often been used to characterize these intracellular bodies, a hypothesis is, therefore, advanced that lysosome may play a key role in hormonal regulation of luteal function. According to the Law of Unity of Opposites, it is suggested that both PGF2α, and LH may regulate the luteal function by acting, either directly or indirectly, on the lysosomal membrane in an opposite way: one exerts an altering and the other, a stabilizing effect on the membrane permeability of lysosomes in the luteal cells. Evidences to sustain such a hypothesis have been presented and discussed.

本研究用组织化学方法着重探讨PGF_(2α)对孕鼠黄体中3β-OH-脱氢酶和酸性磷酸酶活性的影响,并讨论了垂体因素(LH)与黄体酶活性变化和PGF_(2α)的关系。 实验都系妊娠第9天的大鼠;分为五组:(1)PGF_(2α)处理组;(2)对照组;(3)摘除垂 体组;(4)摘除垂体后立即注射外源LH组;(5)摘除垂体后同时注射LH和PGF_(2α)组。五组均在第十二天取材,新鲜冰冻切片,组织化学方法显色。 实验证明,PGF_(2α)与黄体的3β-OH-脱氢酶和酸性磷酸酶都有密切关系,它有抑制前者和激活后者活性的能力,而LH能维持和增强3β—OH—脱氢酶的活性,根据摘除垂体同时注射LH和PGF_(2α)的实验揭示,PGF_(2α)在一定程度上与LH有拮抗作用。因此,认为PGF_(2α)的作用部位在卵巢一级而不通过垂体。实验结果还表明孕鼠经PGF_(2α)处理后,酸性磷酸酶活性比对照组酶活性有显著的增强,由于细胞解体与溶酶体膜的通透性改变和它所释放的水解酶,特别是酸性磷酸酶有密切的关系,而酸性磷酸酶活性变化又与激素有关,因此作者们认为溶酶体在激素调节黄体功能中起着重要的作用,改变或稳定溶酶体膜透性会产生不同的生理效...

Radix trichosanthes is an abortifacient drug of mid-gestation and is extracted from the root tuber of Trichosanthes kirilowii Maxim (Cucurbitaceae).The purified effective principle is a basic protein of molecular weight of appoximately 18,000 and is named "Trichosan'thin".It is proved to be very effective in abortion induction of mid-gestation,particularly effective in treating ectopic pregnancy,hydatidiform mole and invasive mole,and it has also some therapeutic action on choriocarcinoma.Based upon the experimental results on its initial site of action,its morphological and functional injury on trophoblast cells of placenta both in vivo and in,vitro and its effect on prostaglandin synthesis,the following conclusions are drawn concerning the mechanism of abortifacient action of triohosanthin:(1)Trichosanthin exerts its action directly on the placental trophoblasts and possesses a certain degree of specificity.(2)It selectively produces necrotic degeneration of the syneytiotrophoblasts of placental villi,resulting in fragments of the disintegrated cells clumped in the blood sinus,and the coagulation of blood causing circulation hinderan'ce and followed by large scale tissue necrosis.The necrosis of placental villi is considered to be the primary response.(3)Beside structural injuries the impairemerit of functional activities were also observed.The concentrations of HCG and steroid hormones fell rapidly below the threshold values of threatened abortion.Serious structural and functional injuries brought about destructive effects upon the normal endocrine relationship between the mother and fetus and upon metabolic exchanges.It was further postulated that through certain unknown mechanism the synthesis of prostaglandin was increased,uterine contraction was initiated and abortion ensued.In summary,trichosanthin,a plant protein discovered from Chinese medical herbs,is a drug for abortion induction and also a drug against trophoblastie neoplasms.The preliminary elucidation of the mechanism of this drug on abortion induction has afforded basis for the clinical application with better efficacy and its possible use for an abortifacient in early pregnancy as well as for the discovery of newer cancer chemotherapeutie agents.
