    Objective: To evaluate abortifacient and antioxidant activity of Musa rosacea (M. rosacea).Methods:Abortifacient activity was evaluated in rats, compared with standard drug (Mifepristone) and antioxidant activity was evaluated by using three free radicals (Superoxide, Hydroxyl and DPPH). Results: The extracts showed preimplantation loss, postimplantation loss of implantations and decreased the survival ration of foetuses. Among all extracts hydroalcoholic extract showed better activity. The selected plant extracts showed concentration dependent percentage inhibition of free radicals. Among four extracts hydroalcoholic extract showed better activity with IC50 values on superoxide, hydroxyl and DPPH radicals were 180 µg, 218 µg and 116 µg. Conclusion:From the results obtained during the study it could be concluded that M. rosacea extracts have abortifacient and antioxidant components and the results support its folklore usage as abortifacient plant. Further is necessary for isolation and characterization of bioactive molecules which are responsible for these activities.

    Full Text Available Objetivo: verificar a associação entre o uso de abortivos durante o primeiro trimestre de gestação e a ocorrência de defeitos congênitos em recém-nascidos (RN. Métodos: estudo caso-controle com amostra de 800 nativivos, em maternidade pública de Salvador, Bahia, pelo período de um ano. Eram selecionados os seis primeiros nascimentos ocorridos em um só dia, sendo feitas consultas aos prontuários para verificação do registro de defeitos congênitos. Nos casos positivos eram observados os bebês afetados e realizada entrevista com as puérperas para o levantamento de antecedentes gestacionais e genéticos, utilizando questionário como instrumento de coleta de dados. Posteriormente os dados eram inseridos em programa de computador Epi-Info 5.0 para análise estatística. Resultados: as puérperas estudadas foram predominantemente de classe socioeconômica baixa (74,8%, sem escolaridade ou apenas 1º grau (61,1%. A taxa geral de defeitos congênitos foi de 4,7%. Entre as puérperas, 16% relataram a ingestão de substâncias abortivas no primeiro trimestre de gestação e 10,9% destas tiveram filhos com malformações. Nas crianças em que as mães não utilizaram abortivos essa incidência foi 3,6%. Os principais agentes usados como abortifacientes foram os chás medicinais e o misoprostol (Cytotec. O alumã (Vermonia baiensis Tol e o espinho cheiroso (Kanthoxilum shifolium Lam foram as plantas mais utilizadas inadequadamente, pois não apresentam propriedades abortivas, justificando assim a sua ineficácia. Conclusão: o presente estudo evidencia que tentativas de abortamento são práticas muito usuais em populações de baixa renda. Revela ainda que o uso de abortivos provoca um percentual significativo de malformações congênitas em bebês nativivos.Purpose: to verify the association of the use of abortifacient drugs during the first 3 months of gestation with the occurrence of congenital malformations in live births.

  3. Progress with contraceptives and abortifacients.

    In Canada and most other comparatively rich countries, the total fertility rate (TFR) declined from approximately 2.5 in 1970 to 1.6-1.9 in 1990. The reduction was even greater in some countries such as China, Korea, Singapore, Mauritius, Barbados, Cuba, Guadeloupe, and Puerto Rico. TFR, however, has fallen little, if at all, in many poor countries; it remains at 8.1 in Kenya and has increased from already previously high levels in Somalia, Benin, Malawi, and Rwanda. The use of contraception has been instrumental in reducing fertility. An estimated 70% of married women in rich countries use contraceptives, and a larger proportion in Eastern Asia, but only less than 15% in Africa. Education for women generally increases the level of contraceptive use. Rates, however, depend upon the degree of both acceptance and availability. An estimated 20% of births in developing countries are unwanted, so it would seem that greater availability and variety of contraceptives could lead to reductions in fertility. Research into better contraceptive technology is frustrated by paternalism, most organized religions, concern over possible future legal liability, and fear of adverse health side effects, especially in North America. Depo-Provera and RU-486, for example, have yet to be licensed in Canada for use as contraceptive agents. Research nonetheless moves forward. A vaccine against pregnancy is reportedly being developed which may be available before the turn of the century. Clinical trials have been held, and the vaccine has been found to be effective in most women, lacking in side effects, and reversible. The prototype requires a series of injections. Elsewhere, the Alza Corporation of California is working on a transdermal patch to control fertility, while some success has been reported in trials of testosterone, alone or combined with a gonadotropin-releasing hormone, to suppress sperm production in men.

  4. [Abortifacient effect of hormonal contraceptives: a review].

    Most of the scientific community, as well as in a sector of international Law, when referring to the unborn embryo, pregnancy must be defined as the period extending from implantation to natural birth. This implies some novelty, such as the redefinition of abortion as the elimination of the embryo only within this period, and the extension of contraception to any means that impedes the union of the gametes as a consequence of a sexual intercourse, or also that which eliminates the product of conception prior to its implantation. Therefore, the pharmaceutical industry markets, under the name of contraceptives, products that act also by means of an anti-implantation mechanism. This fact has great ethical implications regarding the respect for the embryo which require a reflection on the moral valuation of the prescription, dispensation and use of these means. One may ask: which of the contraceptive means actually present in the market include an anti-implantation effect? What mechanisms contribute to their pharmacological action and in what measure do they do this? This is what we have studied in this article, based on the available scientific bibliography. We have basically fulfilled a double objective: updating and completing the studies -few, partial or distant in time- that had this same subject matter; and offering a moral valuation on the use of hormonal contraceptives that may have an anti-implantation effect, from the point of view of the respect due to the embryonic life.

    Full Text Available In tsetse flies, nutrients for intrauterine larval development are synthesized by the modified accessory gland (milk gland and provided in mother's milk during lactation. Interference with at least two milk proteins has been shown to extend larval development and reduce fecundity. The goal of this study was to perform a comprehensive characterization of tsetse milk proteins using lactation-specific transcriptome/milk proteome analyses and to define functional role(s for the milk proteins during lactation. Differential analysis of RNA-seq data from lactating and dry (non-lactating females revealed enrichment of transcripts coding for protein synthesis machinery, lipid metabolism and secretory proteins during lactation. Among the genes induced during lactation were those encoding the previously identified milk proteins (milk gland proteins 1-3, transferrin and acid sphingomyelinase 1 and seven new genes (mgp4-10. The genes encoding mgp2-10 are organized on a 40 kb syntenic block in the tsetse genome, have similar exon-intron arrangements, and share regions of amino acid sequence similarity. Expression of mgp2-10 is female-specific and high during milk secretion. While knockdown of a single mgp failed to reduce fecundity, simultaneous knockdown of multiple variants reduced milk protein levels and lowered fecundity. The genomic localization, gene structure similarities, and functional redundancy of MGP2-10 suggest that they constitute a novel highly divergent protein family. Our data indicates that MGP2-10 function both as the primary amino acid resource for the developing larva and in the maintenance of milk homeostasis, similar to the function of the mammalian casein family of milk proteins. This study underscores the dynamic nature of the lactation cycle and identifies a novel family of lactation-specific proteins, unique to Glossina sp., that are essential to larval development. The specificity of MGP2-10 to tsetse and their critical role during lactation suggests that these proteins may be an excellent target for tsetse-specific population control approaches.

  14. Artifacts, intentions, and contraceptives: the problem with having a plan B for plan B.

    Reed, Philip A

    2013-12-01

    It is commonly proposed that artifacts cannot be understood without reference to human intentions. This fact, I contend, has relevance to the use of artifacts in intentional action. I argue that because artifacts have intentions embedded into them antecedently, when we use artifacts we are sometimes compelled to intend descriptions of our actions that we might, for various reasons, be inclined to believe that we do not intend. I focus this argument to a specific set of artifacts, namely, medical devices, before considering an extended application to emergency contraceptive devices. Although there is some debate about whether emergency contraception has an abortifacient effect, I argue that if there is an abortifacient effect, then the effect cannot normally be a side effect of one's action.

    1999-12-01

    A non proteinaceous extract of Bromelia pinguin fruit was examined for activity on the rat uterus in vivo and in vitro. The in vivo experiments involved pregnant rats given the extract intraperitoneally. These rats did not abort nor were any foetal deformities observed. The extract inhibited spontaneous activity of the pregnant rat uterus in vitro. These results do not support the claimed folklore use of the plant as an abortifacient. The extract of Bromelia pinguin fruit may have some utero-active compound which inhibits uterine motility.

    2014-09-01

    Mifepristone (RU486) is a born-for-woman molecule discovered three decades ago. Unlike those antihypertensive and antipsychotic pharmaceutical blockbusters, this abortifacient offers relatively low profit potential. Current understanding of mechanism of action of mifepristone and its on-going clinical trials are changing our views on the drug beyond its abortifacient scope. Here we briefly review its metabolism and pharmacokinetic properties including its unique enterohepatic circulation, its mechanisms of actions involving antiprogesterone and antiglucocorticoid, growth inhibition of various cancer cell lines, suppression of invasive and metastatic cancer potential, downregulation of Cdk2, Bcl-2, and NF-kappa B, interference of heterotypic cell adhesion to basement membrane, and cell migration. We comprehensively analyze recent results from preclinical and clinical studies using mifepristone as an anticancer drug for breast, meningioma, and gliomas tumors in the central nervous system, prostate cancer, ovarian and endometrial cancer, and gastric adenocarcinoma. Although mifepristone has more benefits for global public health than we originally thought, its effect as a postmetastatic chemotherapeutic agent is limited. Nonetheless, owing to its unique safe, metabolism and other pharmacological properties, metapristone (the primary metabolite of mifepristone) may have potential for cancer metastatic chemoprevention.

    This study investigated the participation of infectious agents in spontaneous abortions and reproductive problems at eight dairy cattle herds from three geographical regions of Brazil. Fourteen aborted fetuses and the organ sections of one cow with history of repeated abortions were received for pathological evaluations and molecular diagnostics. PCR/RT-PCR assays targeted specific genes of abortifacient agents of cattle: bovine viral diarrhea virus (BVDV), bovine herpesvirus 1 (BoHV-1), Listeria monocytogenes, Neospora caninum, Leptospira spp., Brucella abortus, and Histophilus somni. Six fetuses were adequate for pathological investigations; one of these did not demonstrate remarkable pathological alterations. Significant histopathological findings included vasculitis, hemorrhage, and fibrinous thrombosis of the cerebrum (n = 4); necrotizing myocarditis (n = 3); and hemorrhagic enteritis (n = 3). The placenta and uterus of the cow as well as the kidney, pancreas, and liver of her aborted fetus contained H. somni DNA and demonstrated histopathological evidence of histophilosis. All fetuses contained H. somni DNA in multiple organs. Coinfections of H. somni with B. abortus (n = 2), N. caninum (n = 2), BVDV (n = 1), and BoHV-1 (n = 1) were identified; two fetuses demonstrated three pathogens. These findings suggest that H. somni was associated with the spontaneous abortions and reproductive problems of these herds. However, the exact cause of fetal death might not be attributed only to H. somni in all aborted fetuses, since some of these were infected with other abortifacient agents.

  3. Mechanism of action of levonorgestrel emergency contraception.

    Kahlenborn, Chris; Peck, Rebecca; Severs, Walter B

    2015-02-01

    There has been much debate regarding levonorgestrel emergency contraception's (LNG-EC's) method of action since 1999 when the Food and Drug Administration first approved its use. Proponents of LNG-EC have argued that they have moral certitude that LNG-EC works via a non-abortifacient mechanism of action, and claim that all the major scientific and medical data consistently support this hypothesis. However, newer medical data serve to undermine the consistency of the non-abortifacient hypothesis and instead support the hypothesis that preovulatory administration of LNG-EC has significant potential to work via abortion. The implications of the newer data have important ramifications for medical personnel, patients, and both Catholic and non-Catholic emergency room protocols. In the future, technology such as the use of early pregnancy factor may have the potential to quantify how frequently preovulatory LNG-EC works via abortion. Lay Summary: How Plan B (levonorgestrel emergency contraception) works has been vigorously debated ever since the Food and Drug Administration approved it in 1999. Many doctors and researchers claim that it has either no-or at most-an extremely small chance of working via abortion. However, the latest scientific and medical evidence now demonstrates that levonorgestrel emergency contraception theoretically works via abortion quite often. The implications of the newer data have important ramifications for medical personnel, patients, and both Catholic and non-Catholic emergency room rape protocols. PMID:25698840

    Full Text Available Aglepristone is a safe abortifacient in cats, dogs and rabbits. Although no serious side effects have been reported, there is no information available about the effects of the medicine on haematological parameters. For the first time clinical and ultrasonographic features and haematological profiles were evaluated in rabbits treated with aglepristone 15 and 16 days after mating. Ten healthy 10–14 month-old New Zealand White female rabbits were mated with fertile bucks and pregnancies were confirmed by ultrasound 15 days later. Of these, 5 does were treated with aglepristone (test group, n = 5 whilst the remaining five (control group, n = 5 were treated with a saline solution (0.9% NaCl. The treatment dose was 10 mg⁄kg body weight, administered subcutaneously once daily on two consecutive days (day 15 and 16 post mating. Ultrasonographic, clinical and haematological assessments were performed daily. Aglepristone treatment induced embryonic fluid resorptions without foetal death in mid-gestation terminations. Following ultrasonographic and haematological examinations, it was established that aglepristone is a safe abortifacient in rabbits.

    Full Text Available Campylobacter jejuni is a leading cause of human gastrointestinal disease and small ruminant abortions in the United States. The recent emergence of a highly virulent, tetracycline-resistant C. jejuni subsp. jejuni sheep abortion clone (clone SA in the United States, and that strain’s association with human disease, has resulted in a heightened awareness of the zoonotic potential of this organism. Pacific Biosciences’ Single Molecule, Real-Time sequencing technology was used to explore the variation in the genome-wide methylation patterns of the abortifacient clone SA (IA3902 and phenotypically distinct gastrointestinal-specific C. jejuni strains (NCTC 11168 and 81-176. Several notable differences were discovered that distinguished the methylome of IA3902 from that of 11168 and 81-176: identification of motifs novel to IA3902, genome-specific hypo- and hypermethylated regions, strain level variability in genes methylated, and differences in the types of methylation motifs present in each strain. These observations suggest a possible role of methylation in the contrasting disease presentations of these three C. jejuni strains. In addition, the methylation profiles between IA3902 and a luxS mutant were explored to determine if variations in methylation patterns could be identified that might explain the role of LuxS-dependent methyl recycling in IA3902 abortifacient potential.

    Full Text Available Dried flowers of Daphne genkwa Sieb. et Zucc. (Thymelaeaceae are a Chinese herbal medicine used as an abortifacient with purgative, diuretic and anti-inflammatory activities. However, the activity of this medicine against enteroviral infections has not been investigated. The water-extract of dried buds of D. genkwa Sieb. et Zucc. (DGFW was examined against various strains of enterovirus 71 (EV71 by neutralization assay, and its initial mode of action was characterized by time-of-addition assay followed by attachment and penetration assays. Pretreatment of DGFW with virus abolished viral replication, indicating that DGFW inhibits EV71 by targeting the virus. GFW exerts its anti-EV71 effects by inhibiting viral entry without producing cytotoxic side effects and thus provides a potential agent for antiviral chemotherapeutics.

    Full Text Available Chlamydophila abortus (C. abortus is an important abortifacient agent in bovines and ovines. Clinical diagnosis of the disease is often difficult. An early diagnosis can be achieved based on direct demonstration of the organism in clinical material and through the cultural recovery of the organism in embryonated chicken egg. For confirmatory diagnosis antigen detection methods or serological techniques can be adopted. The present study is aimed at the confirmatory diagnosis of C. abortus infection by indirect immunofluorescence technique following the isolation of the organism in cell culture. Specific apple green fluorescing inclusions of C. abortus in McCoy cell lines was detected from 72 h to 96 h post infection employing anti-chlamydial group specific monoclonal antibodies. Thus, a confirmatory diagnosis of the infection was possible with this study. [Vet. World 2011; 4(10.000: 473-474

    Full Text Available Petiveria alliacea (Phytolaccaceae is a bush widely distributed in South America including Brazil, where it is popularly known as "guiné", pipi", "tipi" or "erva-de-tipi". Brazilian folk medicine attributes to the hot water infusion of its roots or leaves the following pharmacologicalproperties: antipyretic, antispasmodic, abortifacient, antirrheumatic, diuretic, analgesic and sedative. The present study has evaluated the alleged effects of P. alliacea on central nervous system (CNS, particularly, the sedative and analgesic properties of root crude aqueous extract of this plant in mice and rats. This extract showed an antinociceptive effect in acetic acid - acetylcholine - and hypertonic saline - induced abdominal constrictions, but not in hot-plate and tail flick tests P. alliacea did not produce any CNS depressor effect. Thus its antinociceptive action in animals can be responsible by its poplar use as an analgesic.

    Medicaments are used to prepare for instrument abortions in the 1st trimester and as inducers of abortion in the 2nd trimester. The effects, side effects, and dangers depend on the substances used and the route of application, which can be vaginal, cervical, injection, instillation, extraamniotic, intraamniotic, intravenous, or intramuscular. In the past, intraamniotic instillation of a 20% salt solution was the most common 2nd trimester method in Japan, the US, and Eastern Europe, giving a success rate of 90%. Serious side effects prompted substitution of extraamniotic instillation, which rarely produces serious side effects. Instillation of a 60% urea solution into the amniotic fluid in combination with oxytocin or prostaglandin produces an abortion in 13-21 hours, with a failure rate of 3% and a frequency of cervical laceration of under 1%. Extraamniotic use of a .1% solution of rivanol yields a success rate of about 85%, with a relatively long average time to explusion of 24-41 hours. In case of failure the procedure can be repeated. The advantage of the Rivanol method is the rarity of infectious complications. Alcohol is not used as a human abortifacient because it produces necrosis in the decidua and placenta. Prostaglandins are used in most 2nd trimester abortions. Research is underway to identify derivatives that will have an extended uterine impact without serious side effects. Different routes of administration have different effectiveness rates and dangers. All prostaglandins cause side effects including pain during uterine contractions, gastro-intestinal reactions, nausea, vomiting, fever, and headaches. Specific preparations are associated with other effects, some of them life-threatening. Emergency treatment should be available when these substances are used. Adjuvant measures may be employed before adminstration of an abortifacient agent to soften the cervix, or after administration to hasten the procedure. The choice of procedure depends upon the

    Objective:To assess the effect of plumbagin-free alcohol extract (PFAE) ofPlumbago zeylanica Linn. (Plumbaginaceae) (P. zeylanica) root, on female reproductive system and fertility of adult female wistar rats.Methods: After the oral acute toxicity study, thePFAE was administered at two dose levels to perform the estrous cycle study, anti-implantation and abortifacient activity and hormonal analysis. However, the estrogenic/antiestrogenic activity was evaluated at only one most effective dose.Results:LD50cut-off was5 000 mg/kg body weight. The extract exhibited significant anti-implantation and abortifacient activity at the tested dose levels (300 and500 mg/kg,p.o.) (P<0.01). The extract dose-dependently decreased the levels of serum progesterone, follicle stimulating hormone and luteinizing hormone, while a dose-dependent increase was observed in the concentration of serum prolactin. The extract did not show any significant changes in structure and function of uterus when given alone, but when given along with ethinyl estradiol, it exhibited significant antiestrogenic activity in immature overiectomized female rats(P<0.001). Biochemical parameters in the serum/blood and haematological parameters did not show appreciable changes throughout and after the course of investigation. However, all the altered parameters returned to normalcy within30 days following withdrawal of treatment. Conclusions: All findings suggest that the antifertility activity of extract could possibly be through the changes in the implantation site, altered hormonal levels, prolonged estrous cycle and anti-estrogenic activity. Hence, the extract possesses reversible antifertility activity without adverse toxicity in female rats.

    Full Text Available Abstract Background Q fever, a worldwide zoonotic disease caused by Coxiella burnetii, is endemic in northern Spain where it has been reported as responsible for large series of human pneumonia cases and domestic ruminants' reproductive disorders. To investigate pathogen exposure among domestic ruminants in semi-extensive grazing systems in northern Spain, a serosurvey was carried out in 1,379 sheep (42 flocks, 626 beef cattle (46 herds and 115 goats (11 herds. Serum antibodies were analysed by ELISA and positive samples were retested by Complement Fixation test (CFT to detect recent infections. Results ELISA anti-C. burnetii antibody prevalence was slightly higher in sheep (11.8 ± 2.0% than in goats (8.7 ± 5.9% and beef cattle (6.7 ± 2.0%. Herd prevalence was 74% for ovine, 45% for goat and 43% for bovine. Twenty-one percent of sheep flocks, 27% of goat and 14% of cattle herds had a C. burnetii seroprevalence ≥ 20%. Only 15 out of 214 ELISA-positive animals reacted positive by CFT. Age-associated seroprevalence differed between ruminant species with a general increasing pattern with age. No evidence of correlation between abortion history and seroprevalence rates was observed despite the known abortifacient nature of C. burnetii in domestic ruminants. Conclusions Results reported herein showed that sheep had the highest contact rate with C. burnetii in the region but also that cattle and goats should not be neglected as part of the domestic cycle of C. burnetii. This work reports basic epidemiologic patterns of C. burnetii in semi-extensive grazed domestic ruminants which, together with the relevant role of C. burnetii as a zoonotic and abortifacient agent, makes these results to concern both Public and Animal Health Authorities.

    Misoprostol, a prostaglandin E1 analogue indicated for ulcer treatment, has been widely used as an abortifacient by women in Brazil, where abortion is legal only in cases of rape or incest, or to save the woman's life. Because misoprostol is an inefficient abortifacient, many women who use it have incomplete abortions and need uterine evacuation. We reviewed the records of women admitted to the main obstetric hospital of Fortaleza, capital of Ceará state, Brazil, between January, 1990, and July, 1992, for uterine evacuation after induced abortion. The number of incomplete abortions induced by misoprostol increased substantially during the first half of 1990, and declined thereafter. Of the 593 cases in 1991, 75% were related to misoprostol, 10% to the use of other specified drugs, and 6% to unspecified drugs. For the remaining 9% the procedure used was not recorded; these included 3% in whom abortion had been induced by a clandestine abortionist. The number of uterine evacuations per month fell from 89 in August, 1990, to 62 in July, 1991, when sales of misoprostol in Ceará state were suspended. The fall continued after the sale of misoprostol ceased, to about 20 cases in December, 1991; numbers remained around this level until June, 1992, sustained by clandestine sales. The lack of access to contraception is the main reason for the large numbers of unplanned pregnancies and is a major public health issue for Brazilian women. The prohibition of abortion creates a void in which misuse of medicines is one extra complication, mainly because of the poor control of drug marketing. PMID:8098403

    Recent large epidemiological studies demonstrated benefit of oral contraceptives in reducing cancer risk, and our analysis also showed molecular and cellular similarities between embryo implantation and CTCs adhesion-invasion to endothelium. We here hypothesize that abortion traditional Chinese medicine (TCM) may serve well for pre-metastatic chemoprevention. To test the hypothesis, we selected the safe and well-known abortifacient TCM Murraya paniculata and identified a most-promising extracted fraction G (containing flavonoids and coumarins) from its many raw ethanol/dichloromethane extracts by using the bioactivity-guided fast screen assay. G showed free radical scavenging effect, and specifically inhibited both embryo implantation to human endometrial bed and cancer HT29 cells to human endothelium in a concentration-dependent manner (1-30 μg/mL) without significant cytotoxicity demonstrated by its high adhesion inhibition ratio. The inhibition may result from its down-regulation on expression of integrin β1 and α6, and CD44 on HT29 cells, as well as E-selectin on endothelial cells. Furthermore, G inhibited invasion and migration of HT29 cells. Pretreatment followed by one-month oral administration of G to the immunocompetent mice inoculated with mouse melanoma cells produced significant inhibition on lung metastasis without marked side effects. Collectively, this paradigm-shifting study provides, for the first time, a new strategy to discover safe and effective pre-metastatic chemopreventives from abortion TCM.

    Full Text Available Brucellosis is one of the most important zoonotic diseases and is a significant cause of abortion in animals. Brucella melitensis strain Rev. 1 is recommended as the most effective vaccine for small ruminants but the application of full doses in adult animals is restricted. This study was conducted to determine a proper reduced dose of vaccine which confers protection but which is not abortifacient in Iranian fat-tailed sheep. A total of 51 non-vaccinated pregnant ewes were divided into three main groups and several subgroups. Ewes in different groups were vaccinated at different stages of pregnancy and various subgroups were subcutaneously immunised with different quantities of the micro-organism (7.5 × 106, 106, 5 × 105. Ewes again became pregnant a year later and were challenged with the wild-type strain to evaluate the protection conferred. Results revealed that the proportion of vaccination-induced abortions was significantly higher in ewes immunised with 7.5 × 106 Rev. 1 organisms than in those which received 106 or 5 × 105 bacteria. While 80% of non-vaccinated ewes aborted after challenge, none of the vaccinated ewes aborted post-challenge. This study indicated that a reduced dose of Rev. 1 vaccine containing 106 or 5 × 105 live cells could be safely used to induce protection in Iranian fat-tailed sheep at various stages of pregnancy.

    Holoptelea integrifolia Roxb. (Indian Elm) is a very useful and popular traditional medicinal plant in India. During the last three decades, apart from the chemistry of plant compounds, considerable progress regarding the biological activity and medicinal applications of Indian Elm has been achieved. Ethno-medically, the leaves and stem bark of this plant have been used by tribes as antiviral, antioxidant, antimicrobial, abortifacient preparations and in the management of cancer. Recent studies on plant show that it has potential to fight against tumor and obesity as well. Phytochemical investigation shows the presence of chemical constituents such as terpenoids, alkaloids, glycosides, carbohydrates, steroids, sterols, saponins, tannins, proteins and flavanoids. The isolated principles such as β-amyrin, β-sitosterol, holoptelin-A, holoptelin-B, hederagenin, hexacosanol, β-D-glucose, friedelin, epifriedelin, 2-amino naphthoquinone, 1,4-naphthalenedione, are considered as responsible for various activities. This review highlights the traditional uses, reported biological/pharmacological activities, isolated compounds and therapeutic applications of Holoptelea integrifolia which might be helpful for scientists and researchers to find out new chemical entities responsible for its claimed traditional uses.

    The type-I ribosome-inactivating protein trichosanthin (TCS) has a broad spectrum of biological and pharmacological activities, including abortifacient, anti-tumor and anti-HIV. We found for the first time that TCS induced production of reactive oxygen species (ROS) in JAR cells by using fluorescent probe 2',7'-dichlorofluorescin diacetate with confocal laser scanning microscopy. TCS-induced ROS showed dependence on the increase in intracellular calcium and on the presence of extracellular calcium. The production of ROS increased rapidly after the application of TCS, which paralleled TCS-indued increase in intracellular calcium monitored using fluo 3-AM, suggesting that TCS-induced ROS might mediate by the increase in intracellular Ca2PLU concentration. Simultaneous observation of the nuclear morphological changes and production of ROS in JAR cells with two-photon laser scanning microscopy and confocal laser scanning microscopy revealed that ROS involved in the apoptosis of JAR cells, which was confirmed by that antioxidant (alpha) -tocopherol prevented TCS-induced ROS formation and cell death. The finding that calcium-dependent TCS-induced ROS involved in the apoptosis of JAR cells might provide new insight into the anti-tumor and anti-HIV mechanism of TCS.

    Ruta chalepensis L. (Rutaceae), is an ancient aromatic medicinal plant still used in the traditional medicine of many countries as a laxative, antiinflammatory, analgesic, antispasmodic, abortifacient, antiepileptic, emmenagogue and for dermatopathy treatment. Regarding increasing prevalence of mycotoxins and inefficiency of methods used to decrease them, it is possible to use plants metabolites to decrease mycotoxins. This study was carried out to evaluate chemical composition, antifungal and anticandidal activities of R. chalepensis extracts. The chemical composition of its essential oil was analyzed by gas chromatography coupled with mass spectrometry (GCMS). The major components of R. chalepensis essential oil were menthol (49.92%), linalool (31.1%) and 2-hexanal (5.2%). The antifungal and anticandidal effects of the essential oil and methanolic extract of R. chalepensis leaves were studied by disc diffusion assay and broth dilution method. The obtained results showed that R. chalepensis extracts had a significant fungicidal effect against Aspergillus niger, Aspergillus flavus and Candida albicans. The inhibition zones diameters and the minimum inhibitory concentration values for tested microorganisms were in the range of 11-17 mm and 3.25-6.25% (v/v), respectively. The methanolic extract showed much better antimicrobial activity than the essential oil against three tested micro-organisms

    Fenugreek (Trigonella foenum graecum), used as traditional medicine and natural additive food, has been shown to exert significant antiatherogenic, antidiabetic, antianorexic, antioxidant, anticarcinogenic, antihyperlipidemic, galactogogue and anti-inflammatory effects in several human and animal models. Besides, several medicinal pharmaceutical and nutraceutical properties, fenugreek have toxic effects as well. The aim of this review is discuss the cumulative evidence, which suggests that consumption of fenugreek induced some serious toxicological side effects. In this review, many teratogenic effects of fenugreek, from congenital malformations to death, were reported in human, rodent, rabbit, and chick. Moreover, results obtained in rats, mice and rabbits show a testicular toxicity and anti-fertility effects in male associated with oxidative stress and DNA damage, as well as anti-fertility, antiimplantation and abortifacient activity in females related to saponin compound of fenugreek which suggest that fenugreek is not recommended for use during pregnancy. Indeed, the consumption of fenugreek should be avoided for persons having peanut and chickpeas allergy because of possible cross-reactivity as well as chronic asthma. Accumulating evidence suggest also that fenugreek may have neurodevelopmental, neurobehavioral and neuropathological side effects. It is suggested that future studies would be conducted to identify molecular and cellular mechanisms underlying the fenugreek toxicological properties. PMID:27498339

    Full Text Available Antidiabetic activity of trigonelline and antifertility activity of fenugreek seeds have been reported. However, the effect of trigonelline on fertility is not reported. The aim of the study was to determine the estrogenic activity of trigonelline (75 mg/kg as well as its effect on fertility in rats. The estrogenic activity was assessed by the vaginal cornification method. Trigonelline was administered on days 1-7 of pregnancy. The animals were anesthetized and laprotomy was carried out on day 10. The number of implantation sites was counted. The wound was sutured and animals were allowed to recover. The number of pups born after 21 days was counted. Trigonelline was safe up to dose of 5000 mg/kg orally. Trigonelline (75 mg/kg did not alter the estrous cycle of rats. Nonsignificant difference in the number of implants and pups born was observed in the trigonelline group compared to the control group. The lack of abortifacient activity or teratogenicity confirms the safety of trigonelline during pregnancy in rats.

The fruit possesses stimulant, antispasmodic and carminative properties and is used traditionally as an important remedial agent for flatulence, atonic dyspepsia, diarrhea, abdominal tumors, abdominal pains, piles, and bronchial problems, lack of appetite, galactogogue, asthma and amenorrhoea. Medicinally, it has been proven to possess various pharmacological activities like antifungal, antioxidant, antimicrobial, antinociceptive, cytotoxic, hypolipidemic, antihypertensive, antispasmodic, broncho-dilating actions, antilithiasis, diuretic, abortifacient, antitussive, nematicidal, anthelmintic and antifilarial. Further, studies reveal the presence of various phytochemical constituents mainly carbohydrates, glycosides, saponins, phenolic compounds, volatile oil (thymol, γ-terpinene, para-cymene, and α- and β-pinene, protein, fat, fiber and mineral matter containing calcium, phosphorous, iron and nicotinic acid. These studies reveal that T. ammi is a source of medicinally active compounds and have various pharmacological effects; hence, it is encouraging to find its new therapeutic uses.

    The history, circumstances, clinical signs, post mortem lesions, morbidity, mortality and laboratory findings are described in an abortion storm in sheep that occurred in Mpumalanga, South Africa, associated with infection with Arcobacter skirrowii. Altogether, about 200 Suffolk Down ewes lost 60 lambs in late pregnancy or at term. Although only three foetuses were submitted for investigation, two had signs consistent with a diagnosis of A. skirrowii infection and the organism was isolated from the placentas of both specimens. No abortions had occurred in previous years, or have subsequently. There were no animal introductions prior to the outbreak that could have indicated a source of infection. One stillborn lamb submitted subsequently had lesions consistent with dystocia, and the history and circumstantial evidence indicated that dystocia had been a factor in several more losses. No ewes or rams had shown signs of diarrhoea or other diseases associated with A. skirrowii infection. Twenty-two faecal, preputial and vaginal swab specimens taken from six rams and 13 ewes after the abortion event were all negative for A. skirrowii. This is the first report of abortions in sheep associated with A. skirrowiiin South Africa. Because the genus Arcobacter is similar to Campylobacter, it is possible that infection has gone unrecognised in the past. Veterinarians and laboratories should take note and include this genus in the list of potential abortifacient organisms. The possible role of Arcobacter species in other diseases like enteritis and mastitis, as well as the potential role as a zoonosis, must be borne in mind. PMID:27476399

    Shiga toxin producing Escherichia coli (STEC) are bacterial pathogens involved in food-borne diseases. Shiga toxin (Stx) is the main virulence factor of STEC and is responsible for systemic complications including Hemolytic Uremic Syndrome (HUS). It has been previously demonstrated that Shiga toxin type 2 (Stx2) induces pregnancy loss in rats in early stage of pregnancy. The main purpose of this study was to determine if an active immunization prevents Stx2 mediated pregnancy loss and confers passive protective immunity to the offspring. For that purpose Sprague Dawley female rats were immunized with the chimera based on the enzyme lumazine synthase from Brucella spp. (BLS) and the B subunit of Shiga toxin 2 (Stx2B) named BLS-Stx2B. After immunization females were mated with males. At day 8 of gestation, dams were challenged intraperitoneally with a sublethal and abortifacient dose of Stx2. The immunization induced high anti-Stx2B-specific antibody titers in sera and most important, prevented pregnancy loss. Pups born and breastfeed by immunized dams had high anti-Stx2B-specific antibody titers in sera. Cross-fostering experiments indicated that passive protective immunity against Stx2 was transmitted through lactation. These results indicate that immunization of adult female rats with BLS-Stx2B prevents Stx2-induced pregnancy loss and confers anti Stx2 protective immunity to the offspring. PMID:27527816

    Infections due to clonal expansion of highly virulent bacterial strains are clear and present threats to human and animal health. Association of genetic changes with disease is now a routine, but identification of causative mutations that enable disease remains difficult. Campylobacter jejuni is an important zoonotic pathogen transmitted to humans mainly via the foodborne route. C. jejuni typically colonizes the gut, but a hypervirulent and rapidly expanding clone of C. jejuni recently emerged, which is able to translocate across the intestinal tract, causing systemic infection and abortion in pregnant animals. The genetic basis responsible for this hypervirulence is unknown. Here, we developed a strategy, termed "directed genome evolution," by using hybridization between abortifacient and nonabortifacient strains followed by selection in an animal disease model and whole-genome sequence analysis. This strategy successfully identified SNPs in porA, encoding the major outer membrane protein, are responsible for the hypervirulence. Defined mutagenesis verified that these mutations were both necessary and sufficient for causing abortion. Furthermore, sequence analysis identified porA as the gene with the top genome-wide signal of adaptive evolution using Fu's Fs, a population genetic metric for recent population size changes, which is consistent with the recent expansion of clone "sheep abortion." These results identify a key virulence factor in Campylobacter and a potential target for the control of this zoonotic pathogen. Furthermore, this study provides general, unbiased experimental and computational approaches that are broadly applicable for efficient elucidation of disease-causing mutations in bacterial pathogens.

    Full Text Available Moringa oleifera Lam. Is a small or medium-sized tree, about 10m high, found wild in the sub-Himalayan tract. The leaves are rich in vitamin A and C and are considered useful in scurvy and catarrhal affections. The leaves are rich in ascorbic acids, amino acids, sterols, isoquercetin glucoside, carotenes, rhamnetin, kaempferol and kaempferitrin. Flowers are traditionally used as tonic, diuretic and abortifacient considered as anthelmintic and also used to cure inflammation, muscle disease, tumors and enlargement of the spleen. All part of this plant is used for the treatment of ascites, rheumatism. Venomous bites and for enhancing cardiac function. In present study, the anti-inflammatory activity was investigated by employing main model Carrageenan induced paw odema (Winter et al., 1962. The results showed a dose dependent decrease in size of odema when observed at 0hr, 1hr, 2hr, 3hr, and 4hr. This effect corresponded with the maximum effect of test dose at 2 hr (Carrageenan-induced paw. The p value<0.0001 was considered to be statistically significant.

  17. Abortion.

    Churchill, M

    1979-09-15

    I would like to take issue with Dr Colin Brewer's statements concerning intrauterine contraceptive devices and abortion (11 August, p 389). I agree that logically there is no distinction between IUCDs, and other abortifacients used early in pregnancy, and abortion methods used later in pregnancy. However, I disagree with his statement that to make illegal IUCDs and similar methods out of an "obsessive concern for microscopic forms of life" would be "absurd." Firstly, size has never been a criterion for the presence or absence of life, or of its importance. Surely Dr Brewer, MPs, and the public would be outraged by anything less than obsessively careful handling of, say, rabies or smallpox viruses in laboratories. Do not the products of conception, with the full potential of a human being unless actively interfered with by other men (neglecting normal fetal wastage), deserve any less concern? Secondly, mortality should not be determined by practicalities; rather morality should determine one's actions. The question of whether IUCDs and other such procedures should remain legal or be made illegal should not be determined by their efficacy, popularity, or economy. I agree fully with Dr Brewer--abortion is a moral issue and it is a pity that the BMF has not raised the moral issues at stake. Particularly so, as Lord Denning put it "...without morality there can be no law." I personally subscribe to the Hippocratic Oath. PMID:497769

    Recent large epidemiological studies demonstrated benefit of oral contraceptives in reducing cancer risk, and our analysis also showed molecular and cellular similarities between embryo implantation and CTCs adhesion-invasion to endothelium. We here hypothesize that abortion traditional Chinese medicine (TCM) may serve well for pre-metastatic chemoprevention. To test the hypothesis, we selected the safe and well-known abortifacient TCM Murraya paniculata and identified a most-promising extracted fraction G (containing flavonoids and coumarins) from its many raw ethanol/dichloromethane extracts by using the bioactivity-guided fast screen assay. G showed free radical scavenging effect, and specifically inhibited both embryo implantation to human endometrial bed and cancer HT29 cells to human endothelium in a concentration-dependent manner (1–30 μg/mL) without significant cytotoxicity demonstrated by its high adhesion inhibition ratio. The inhibition may result from its down-regulation on expression of integrin β1 and α6, and CD44 on HT29 cells, as well as E-selectin on endothelial cells. Furthermore, G inhibited invasion and migration of HT29 cells. Pretreatment followed by one-month oral administration of G to the immunocompetent mice inoculated with mouse melanoma cells produced significant inhibition on lung metastasis without marked side effects. Collectively, this paradigm-shifting study provides, for the first time, a new strategy to discover safe and effective pre-metastatic chemopreventives from abortion TCM. PMID:26959747

  19. ACLU: strict anti-abortion law could also ban contraceptives.

    Science.gov (United States)

    1991-09-01

    In states that pass very restrictive abortion laws, contraceptives may be outlawed as well. A Louisiana law prohibits abortion, even to save the life of the mother, and defines the moment of conception to be contact between a spermatozoan and an ovum. The law carries a maximum 10 year prison sentence and a $100,000 maximum fine. According to this definition, oral contraceptives, IUDs and Norplant would all be considered abortifacient and would thus be illegal. The American Civil Liberties Union (ACLU) has filled a suit on behalf of the women seeking abortions, the physicians performing abortions, and abortion clinics. There appear to be some problem with banning the contraceptives because the law stipulates that you must terminate the pregnancy with intent and if you don't know you are pregnant, then you can't have intent. Thus contraceptives work without knowledge of pregnancy and should not be included. The ACLU also claims that the definition of conception is not medically or scientifically accepted and as such it is faulty.

    Full Text Available Objectives. Pharmacological and antifertility activity evaluation of Jatropha gossypifolia in rats. Methods. The antifertility activity of the extracts of Jatropha gossypifolia in rats was evaluated using two experimental animal models. Estrogenic activity was evaluated in immature female rats using ethinyl estradiol as standard. Anti-implantation and early abortifacient activity was performed in female Wistar rats by determining the number of implantations and implantation resorptions. Results. In estrogenic activity evaluations, the ethanolic and aqueous extracts offered significant estrogen-like activity at 400 mg kg−1 p.o. by increasing the uterine weight compared to vehicle control group. Ethanolic extract (400 mg kg−1, p.o. treatment significantly decreased the number of implants and increased the number of resorptions compared to vehicle control group. Conclusion. The results of the present study provide the evidence of the anti-fertility activity of Jatropha gossypifolia as claimed in the traditional use. The results are consistent with the literature reports related to the antifertility effect of flower extracts of Jatropha gossypifolia.

    Full Text Available In 2009 the Brazilian Ministry of Health published a document named RENISUS that lists 71 herbs traditionally used in Brazil that could result in phytomedicines to be dispensed by the governmental health care program. This manuscript reviews female reproductive and/or developmental toxicity information of these herbs. More than half (35 of the herbs lack information regarding female reproductive and/or developmental effects. From the fourteen herbs used traditionally to disturb female reproduction, five present experimental data corroborating their actions as abortifacients (Maytenus ilicifolia, Momordica charantia, Plectranthus barbatus, Ruta graveolens or labour facilitator (Bidens pilosa. For 23 of the herbs evaluated experimentally for any type of female reproductive endpoint, only a single study was retrieved and at least twelve of these studies were conducted with a single dose. This scenario suggests that the scientific power of the published information is very low and that a scientifically-based risk/benefit analysis about the use of these herbs during pregnancy is not possible. Considering the appeal that phytomedicines have for pregnant women, usually aware and afraid of the risks that synthetic drugs may have in their pregnancy and progeny, well designed studies evaluating reproductive and/or developmental toxicity of these herbs urge.

    Full Text Available Peganum harmala L. is a plant widely distributed in the Mediterranean region. It is commonly used in traditional medicine in Morocco as sedative and abortifacient but exposes users to the risk of overdose and poisoning. The pharmacologically active compounds of this plant include a number of β-carboline and quinazoline alkaloids responsible of its pharmacological and toxicological effects. We report the case of a 24-year-old woman, 22 weeks pregnant, intoxicated with the seeds of Peganum harmala L. On admission, she had disturbance of consciousness, uterine contraction, and oliguria. Laboratory tests revealed renal failure and liver injury, and she benefited then from hemodialysis. During hospitalization, she was intubated after deterioration of consciousness and presented a spontaneous expulsion of the fetus. After extubation, she kept unusual sequelae: cerebellar ataxia and peripheral polyneuropathy. Physicians in regions using Peganum harmala L. as traditional medicine must be able to detect symptoms of its toxicity, in order to establish early gastrointestinal decontamination. The prognosis of this intoxication is variable; most cases can be managed successfully; but in high doses of intoxication, evolution can be fatal.

  4. The state-of-the-art of emergency contraception with the cutting edge drug

    Sarkar, Narendra Nath

    2011-01-01

    Full Text Available The objective of this study is to evaluate and elucidated the potential of selective progesterone receptor modulators (SPRMs to be an effective emergency contraception (EC. The data are extracted from the literature through the MEDLINE database service from 2000–2010. The SPRMs are in fact progesterone receptor ligands that could bind to progesterone receptor (PR and exert antagonistic, agonistic or mixed agonist-antagonistic effects. These SPRMs are mifepristone, onapristone, asoprisnil, ulipristal, proellex among other compounds. Currently developed SPRMs may exert contraceptive effects by inhibiting ovulation and retarding endometrial synchronization. Low-doses of progesterone antagonists retard endometrial maturation without affecting ovulation. Mifepristone being a SPRM is effective for prevention of pregnancy but with prostaglandin acts as an excellent abortifacient; yet could not compete with levonorgestrel as EC. However, a single dose of 30 mg ulipristal acetate, another SPRM with similar effectiveness and side effect profiles as 1.5 mg levonorgestrel EC, has shown wider ‘window of effect’ by inhibition of the LH peak even if administered at the advanced pre-ovulatory phase, a time when use of levonorgestrel EC is no longer effective. Thus, ulipristal acetate goes one-step ahead of levonorgestrel in the field of emergency contraception treatment. Further studies are needed to explore the potential of other SPRMs to be cutting edge emergency contraceptive drugs.

    A multi-center study was performed in Brazil, Chile, and Mexico to identify factors that may facilitate or hinder the introduction of emergency contraception (EC) as well as perceptions concerning emergency contraceptive pills. Background information on the socio-cultural, political, and legal context and the characteristics of reproductive health services was collected. The opinions of potential users and providers were obtained through discussion groups, and those of authorities and policymakers through semi-structured interviews. Barriers to introduction included: perception of EC as an abortifacient, opposition by the Catholic Church, limited recognition of sexual and reproductive rights, limited sex education, and insensitivity to gender issues. Facilitating factors were: perception of EC as a method that would prevent abortion and pregnancy among adolescents and rape victims; interest in the method shown by potential users as well as by some providers and authorities. It appears possible to reduce barriers through support from segments of society committed to improving sexual and reproductive health and adequate training of health care providers. PMID:14999339

    Full Text Available To characterize the action of 2,3,7,8-tetrachlorodibenzo-p-dioxin (TCDD during both the follicular and luteal phases of the ovarian cycle, the direct effect of TCDD was investigated in vitro using a system of primary monolayer cell culture. Granulosa and theca cells were collected from the preovulatory follicles and cultured as a co-culture, thus resembling follicles in vivo. Luteal cells were isolated from the corpora lutea collected during the midluteal phase. In both cases cells were isolated from the ovaries of animals exhibiting natural estrus cycle. Results of these experiments suggest that TCDD decreases estradiol secretion by follicular cells and progesterone secretion by luteal cells in a dose-dependent manner. It was also shown that TCDD disrupts steroidogenesis through its influence on the activity of enzymes involved in the steroid biosynthesis cascade. In luteal cells, its action is mediated via the aryl hydrocarbon receptor (AhR and is probably independent of estrogen receptor (ER stimulation. Endocrine disruptors that interfere with estradiol production in the follicles can act as ovulatory disruptors, and while interfering with progesterone production by luteal cells they can act as abortifacients.

  9. Commercial availability of misoprostol and induced abortion in Brazil.

    Costa, S H

    1998-12-01

    In Brazil, abortion is only permitted to save the woman's life or in cases of rape. The principal effect of legal restrictions is not to make induced abortion practice less prevalent but to force poor women to resort to abortions performed under unhygienic conditions or attempt self-induced abortion. Within this context, misoprostol, a synthetic analogue of prostaglandin E1, was introduced in the country in 1986. Purchased over the counter in pharmacies, misoprostol has became a popular abortifacient method among Brazilian women. By 1990, about 70% of women hospitalized with abortion-related diagnoses reported use of the drug. In 1991, the Ministry of Health restricted the sale of misoprostol, and in some states its use was totally banned. While the proportion of abortions induced with misoprostol has decreased, the drug continues to be sold on the black market at an inflated value. Research indicates that women have acquired more experience with the drug over time, resulting in lower doses and more effective administration. Several studies show that the rate and severity of complications are significantly less among women who used misoprostol compared with women who used invasive methods. Research also suggests that about half of the women have complete abortion with misoprostol, but seek medical care as soon as they have vaginal bleeding. The experience of Brazilian women with misoprostol is an example of how women when faced with unwanted pregnancy will resort to illegal abortion whatever the costs are to their health. PMID:10075223

    Full Text Available The aim of this study was to present the implications of the use of herbs during pregnancy, pointing out those that should be avoided during this condition because of their abortifacient and/or teratogenic potential. We carried out searches in the databases ScienceDirect, Scielo and Google Scholar, adopting as criteria for inclusion: book chapters and/or complete articles (with abstract, available in English, Portuguese or Spanish, published from 1996 to in 2011. After a pre-selection of 83 articles, 49 bibliographies were used in the manufacturing end of the article, where 25 were from the Scielo database, 18 from ScienceDirect and 6 from Google Scholar. From the articles studied, we identified the four most commonly used plants as emmenagogue/abortifacient agents by patients of the Department of Prenatal SUS: senne, arruda, boldo and buchinha-do-norte or cabacinha. Thus, we conclude that people often adhere to the maxim "if it's natural, it does no harm" in their rational use of natural products, without the right guidance, believing that these products are safe to use. This usage is even more worrisome among the elderly, pregnant women and children. Regarding the safety of these products, some information and reliable data are scarce or contradictory.Este trabalho busca as implicações atuais sobre o uso de plantas medicinais durante a gravidez, alertando sobre aquelas que devem ser evitadas nesse período por serem potencialmente abortivas e/ou teratogênicas.

    The "rightness" of a technology for completing a particular task is negotiated by medical professionals, patients, state institutions, manufacturing companies, and non-governmental organizations.

  13. [About da tai - abortion in old Chinese folk medicine handwritten manuscripts].

    Of 881 Chinese handwritten volumes with medical texts of the 17th through mid-20th century held by Staatsbibliothek zu Berlin and Ethnologisches Museum Berlin-Dahlem, 48 volumes include prescriptions for induced abortion. A comparison shows that these records are significantly different from references to abortion in Chinese printed medical texts of pre-modern times. For example, the percentage of recipes recommended for artificial abortions in handwritten texts is significantly higher than those in printed medical books. Authors of handwritten texts used 25 terms to designate artificial abortion, with the term da tai [see text], lit.: "to strike the fetus", occurring most frequently. Its meaning is well defined, in contrast to other terms used, such as duo tai [see text], lit: "to make a fetus fall", xia tai [see text], lit. "to bring a fetus down", und duan chan [see text], lit., to interrupt birthing", which is mostly used to indicate a temporary or permanent sterilization. Pre-modern Chinese medicine has not generally abstained from inducing abortions; physicians showed a differentiating attitude. While abortions were descibed as "things a [physician with an attitude of] humaneness will not do", in case a pregnancy was seen as too risky for a woman she was offered medication to terminate this pregnancy. The commercial application of abortifacients has been recorded in China since ancient times. A request for such services has continued over time for various reasons, including so-called illegitimate pregnancies, and those by nuns, widows and prostitutes. In general, recipes to induce abortions documented in printed medical literature have mild effects and are to be ingested orally. In comparison, those recommended in handwritten texts are rather toxic. Possibly to minimize the negative side-effects of such medication, practitioners of folk medicine developed mechanical devices to perform "external", i.e., vaginal approaches. PMID:24195336

This paper shows how certain technologies may challenge the meaning of the "job" they are designed to accomplish. Manual vacuum aspiration (MVA) is a syringe device for uterine evacuation that can be used to treat complications of incomplete abortion, known as post-abortion care (PAC), or to terminate pregnancy.

    Full Text Available Abstract Background The epidemiological situation of ovine chlamydial infections in continental Europe, especially Germany is poorly characterised. Using the German state of Thuringia as a model example, the chlamydial sero- and antigen prevalence was estimated in thirty-two randomly selected sheep flocks with an average abortion rate lower than 1%. Seven vaccinated flocks were reviewed separately. Results A wide range of samples from 32 flocks were examined. Assumption of a seroprevalence of 10% (CI 95% at flock level, revealed that 94% of the tested flocks were serologically positive with ongoing infection (i.e. animals with seroconversion in nearly half (47% of the flocks. On the basis of an estimated 25% antigen prevalence (CI 95%, PCR and DNA microarray testing, together with sequencing revealed the presence of chlamydiae in 78% of the flocks. The species most frequently found was Chlamydophila (C. abortus (50% followed by C. pecorum (47% and C. psittaci genotype A (25%. Mixed infections occurred in 25% of the tested flocks. Samples obtained from the vaccinated flocks revealed the presence of C. abortus field samples in 4/7 flocks. C. pecorum was isolated from 2/7 flocks and the presence of seroconversion was determined in 3/7 flocks. Conclusions The results imply that chlamydial infections occur frequently in German sheep flocks, even in the absence of elevated abortion rates. The fact that C. pecorum and the potentially zoonotic C. psittaci were found alongside the classical abortifacient agent C. abortus, raise questions about the significance of this reservoir for animal and human health and underline the necessity for regular monitoring. Further studies are needed to identify the possible role of C. psittaci infections in sheep.

    Full Text Available Papita, a fibrous, juicy and tasty fruit, belonging to family Caricaceae is scientifically known as Carica papaya L. Traditionally, Papaya is used as an abortifacient and as a wound-healer. Furthermore, Papaya possesses several medicinal properties such as anti-hypertensive, anti-oxidant, anti-tumor, anti-fertility, hypo-lipidaemic, anthelmintic, nephro-protective, anti-inflammatory, anti-amoebic, anti-bacterial and anti-sickling property. There are no reports in literature pertaining to CNS actions of Carica papaya. In the light of above, the present study was undertaken to test the antidepressant potential of Carica papaya fruit. Carica papaya pulp (CPP was administered at various concentrations ranging from 4% to 16% w/v, p.o. to Swiss mice for 15 days and Wistar rats for 6 successive days. The antidepressant activity was measured using forced swim test (FST, tail suspension test (TST and reserpine induced hypothermia model. The efficacy of Papaya was compared with standard antidepressant drugs such as fluoxetine (20mg/kg, p.o., imipramine (15mg/kg, p.o. and phenelzine (20 mg/kg, p.o.. The results of the present study showed that Papaya pulp significantly decreased immobility time in both FST and TST models. It also reversed the hypothermia induced by reserpine. The efficacy of Papaya was found to be comparable to fluoxetine, imipramine and phenelzine. Furthermore, Carica papaya juice inhibited the monoamine oxidase MAO-A and MAO-B activity and reduced significantly malondialdehyde (MDA levels. These findings reveal the antidepressant potential of Papaya. The probable mechanism of action for the beneficial effect of Papita in depression appears to be related to its i MAO inhibitory activity ii tyrosine, phenylalanine (NE precursors and tryptophan (5-HT precursor content and iii antioxidant property.

    Toxoplasma gondii and Neospora caninum are two major abortifacient protozoans in domestic small ruminants and cattle, respectively, and they also parasitize a wide range of wildlife. Numerous serosurveys have been conducted in wild ruminants worldwide. However, the potential effect of different ecosystems and management practices on these infections has not been investigated. We studied the prevalence of antibodies to T. gondii and N. caninum in wild ruminants between 2007 and 2012 from four national wildlife reserves: three open space reserves in northwest Spain (Ancares, Mampodre, and Riaño) and a fenced reserve in central Spain (Quintos de Mora). Sera from roe deer ( Capreolus capreolus ) and chamois ( Rupicapra rupicapra ) were collected in Ancares (roe deer), Mampodre (both species), and Riaño (both species), whereas red deer ( Cervus elaphus ) sera were collected only in Quintos de Mora. The results of immunofluorescence antibody tests showed a T. gondii antibody prevalence significantly higher in red deer (13%; 17/131) than in roe deer (2%; 5/228) and chamois (4%; 6/149) (Panimals (2/131 red deer, 2/228 roe deer, and 2/149 chamois). Management measures were implemented in the Quintos de Mora reserve and T. gondii antibody prevalence in red deer decreased from 13% to 2% after 5 yr. In contrast, N. caninum antibody prevalences were very low (hunting reservations studied, so interconnection between sylvatic and domestic life cycles is unlikely. Regardless, a sustainable exploitation of natural resources in wildlife reserves may help to reduce the prevalence of T. gondii infection. PMID:26967135

  19. FDA panel finds mifepristone safe and effective.

    1996-07-26

    At a July 19 hearing, the Food and Drug Administration's Advisory Committee for Reproductive Health Drugs found mifepristone to be safe and effective in inducing abortions early in pregnancy and recommended that the drug be approved for marketing in the US. With a 6-0 vote with two abstentions, the eight-member panel found that mifepristone's benefits were greater than its risks; agreed, 7-0, with one abstention, that it is safe; voted 6-2 to accept data from a French study as sufficient to recommend use in this country; and decided unanimously to reconvene if results from US clinical trials differ significantly from those from France. While the FDA is not required to follow the panel's advice, it is highly uncommon for it to do otherwise. The advisory panel scheduled the hearing in response to an application filed this spring by the Population Council, the nonprofit organization that owns the US patent rights to the drug. The meeting began with a presentation by the Population Council on the results of an American mifepristone trial that involved more than 2000 women and a discussion of the data from studies and practical use in France. The second session brought public testimony from 33 speakers, the majority of whom spoke in favor of the drug's approval. A company plans to manufacture mifepristone once it is approved but refuses to reveal its identity out of concern that it will be a target for anti-choice protests and boycotts. The drug would be marketed by Advances in Health Technology, Inc., an enterprise designated by the Population Council as the exclusive US distributor of mifepristone--the abortifacient marketed as RU486 in France and used by nearly 200,000 women in Europe and elsewhere.

    Besides its importance in cattle, Neospora caninum may also pose a high risk as abortifacient for small ruminants. We have recently demonstrated that the outcome of experimental infection of pregnant sheep with 10(6) Nc-Spain7 tachyzoites is strongly dependent on the time of gestation. In the current study, we assessed peripheral and local immune response in those animals. Serological analysis revealed earlier and higher IFN-γ and IgG responses in ewes infected at early (G1) and mid (G2) gestation, when abortion occurred. IL-4 was not detected in sera from any sheep. Inflammatory infiltrates in the placenta mainly consisted of CD8+ and, to a lesser extent, CD4+ T cells and macrophages (CD163+). The infiltrate was more intense in sheep infected at mid-gestation. In the foetal mesenchyme, mostly free tachyzoites were found in animals infected at G1, while those infected in G2 displayed predominantly particulate antigen, and parasitophorous vacuoles were detected in sheep infected at G3. A similar pattern of placental cytokine mRNA expression was found in all groups, displaying a strengthened upregulation of IFN-γ and IL-4 and milder increases of TNF-α and IL-10, reminiscent of a mixed Th1 and Th2 response. IL-12 and IL-6 were only slightly upregulated in G2, and TGF-β was downregulated in G1 and G2, suggestive of limited T regulatory (Treg) cell activity. No significant expression of TLR2 or TLR4 could be detected. In summary, this study confirms the pivotal role of systemic and local immune responses at different times of gestation during N. caninum infection in sheep. PMID:26739099

    In Brazil, abortion is legally allowed only when it is necessary to save a woman's life or when pregnancy has occurred following rape. Despite this law, induced abortion is widely carried out. This study presents the findings as to the determinants of 2,084 abortions admitted to two major obstetric hospitals in Fortaleza, Brazil, between October 1992 and September 1993. Most of these women (2,074) have admitted an attempt to terminate pregnancy and 10 women were classified as induced abortion cases based on the findings of signs of intervention such as cervical laceration, perforation or foreign bodies in the vagina or uterus. The study findings indicate that self-administration of medicines plays an important role in terminating pregnancy. Among the 2,074 women who admitted to terminating the pregnancy 66% reported using misoprostol to induce abortion. Misoprostol, a prostaglandin E1 analogue indicated for ulcer treatment, has been widely used as an abortifacient by women in Brazil. Misoprostol has some uterine effects but it is not effective in inducing abortion. Among women who were hospitalized for complications resulting from abortion about 59.7% were 20 to 29 years old and 22.6% were aged less than 20. The majority of the women (91.6%) were Catholic and only 4.3% were illiterate. About 62% of the abortion cases lived alone or did not have a stable partner. Most of the women (59.2%) reported less than 2 live births and 11.8% had experienced a previous abortion; 61.1% of the women were not using a contraceptive method at the time of conception. The main reasons for this were "fear of side effects", "did not expect to have sexual intercourse" and "did not expect to get pregnant". The authors suggest that the situation of a high rate of self-inflicted abortion may be changed by the application of an appropriate contraceptive and reproductive health programme. PMID:9008918

    Introducing the post-coital birth control method in the family-planning services of Latin American countries has not been an easy task. Catholic and other conservative groups with great influence in the political arena have time and again stopped it from being adopted as an alternative method and have even succeeded in having it removed from official directives after formal acceptance by health authorities. The main objections are triggered by the erroneous supposition that "emergency contraception" pills are abortifacients. However, a large dose of cultural discrimination against women seems also to be involved. It has been extremely difficult to register dedicated products and make them available in drug-stores and even more difficult to distribute them without charge at public health centers. They are hard to find, expensive, and unavailable to adolescents at risk for unwanted pregnancies and to most low-income women, especially in rural areas. Dissemination of appropriate information has been scarce and slow and there are still great numbers of people that do not understand how or why the method works. Brazil has been the only exception, as its open society has readily accepted this method of contraception. The Latin American Consortium on Emergency Contraception founded in the year 2000 and its regional conference two years later had an important impact on the situation, as they encouraged the coordination of efforts by governmental and nongovernmental entities with those of women's groups to fight for sexual and reproductive rights. A number of studies have shown that the more people learn about emergency contraception, the more they find it acceptable and necessary, and radio spots and other media techniques have begun to educate the public about this matter. In spite of the many difficulties encountered, in the last few years several countries have made strides to include this method in their public health guidelines. However, because of the powerful forces

    Full Text Available A multi-center study was performed in Brazil, Chile, and Mexico to identify factors that may facilitate or hinder the introduction of emergency contraception (EC as well as perceptions concerning emergency contraceptive pills. Background information on the socio-cultural, political, and legal context and the characteristics of reproductive health services was collected. The opinions of potential users and providers were obtained through discussion groups, and those of authorities and policymakers through semi-structured interviews. Barriers to introduction included: perception of EC as an abortifacient, opposition by the Catholic Church, limited recognition of sexual and reproductive rights, limited sex education, and insensitivity to gender issues. Facilitating factors were: perception of EC as a method that would prevent abortion and pregnancy among adolescents and rape victims; interest in the method shown by potential users as well as by some providers and authorities. It appears possible to reduce barriers through support from segments of society committed to improving sexual and reproductive health and adequate training of health care providers.Foram identificados fatores que poderiam facilitar ou dificultar a introdução da anticoncepção de emergência (AE no Brasil, Chile e México.

    The major objective of this experiment was to determine whether the bovine placenta could be stimulated to secrete progesterone, since the bovine placenta secretes little progesterone when the corpus luteum is functional. Secondly, we wanted to determine whether reported abortifacients or progesterone or estrogen receptor antagonists affected bovine placental prostaglandin secretion. The ovine placenta secretes half of the circulating progesterone at day 90 of pregnancy and PGE2 appears to regulate ovine placental progesterone secretion. Calcium has been reported to regulate placental progesterone secretion in cattle. Diced 186-245-day placental slice explants from six Brahman and six Angus cows were incubated in vitro at 39.5 degrees C under 95% air: 5% CO2 at pH 7.2 in 5 ml of M-199 for 1 h in the absence of treatments and for 4 and 8 h in the presence of treatments. Treatments were: vehicle; R24571; compound 48/80; IP3; PGE2; CaCl2; cyclosporin A; lipopolysaccharide (endotoxin) from Salmonella abortus equi., enteriditis, and typhimurium; monensin; ionomycin; arachidonic acid; mimosine; palmitic acid; progesterone, androstenedione; estradiol-17beta; A23187; RU-486; or MER-25. Jugular and uterine venous plasma and culture media were analyzed for progesterone, PGE2 and PGF2alpha by radioimmunoassay (RIA). Plasma hormone data were analyzed by a One-Way Analysis of Variance (ANOVA). Hormone data in culture media were analyzed for breed and treatment effects by a Factorial Design (2 breeds, 2-range of days, 21 treatments) for ANOVA (2 x 2 x 21). Since hormone data secreted by placental tissue in vitro did not differ (P > or = 0.05) by breed or range of days of pregnancy, data were pooled and analyzed by a One-Way ANOVA. Concentrations of PGE2 in uterine venous blood were two-fold greater (P Angus than Brahman cows. PGE2 and PGF2alpha in vehicle controls increased from 4 to 8h (P or = 0.05) Progesterone in culture media treated with RU-486 increased (P or = 0

In intravenous studies the LD(50) using mice was > 80 mg/kg, rats was > 15 mg/kg, and dogs was > 10 mg/kg. The 14-day no observed effect level (NOEL) for the Aloe polysaccharide, acemannan, in the diet of Sprague-Dawley rats, was 50,000 ppm or 4.1 to 4.6 g/kg day(-1). In a 3-month study using mice, Aloe vera (extracted in ethanol) given orally in drinking water at 100 mg/kg produced reproductive toxicity, inflammation, and mortality above that seen in control animals. Aloe vera extracted in methanol and given to mice at 100 mg/kg in drinking water for 3 months caused significant sperm damage compared to controls. Aloe barbadensis extracted with water and given to pregnant Charles Foster albino rats on gestational days (GDs) 0 through 9 was an abortifacient and produced skeletal abnormalities. Both negative and positive results were found in bacterial and mammalian cell genotoxicity assays using Aloe barbadensis-derived material, Aloe Ferox-derived material, and various anthraquinones derived from Aloe. Aloin (an anthraquinone) did not produce tumors when included in the feed of mice for 20 weeks, nor did aloin increase the incidence of colorectal tumors induced with 1,2-dimethylhydrazine. Aloe-emodin (an anthraquinone) given to mice in which tumor cells had been injected inhibited growth of malignant tumors. Other animal data also suggest that components of Aloe inhibit tumor growth and improve survival. Various in vitro assays also demonstrated anticarcinogenic activity of aloe-emodin. Diarrhea was the only adverse effect of note with the use of Aloe-derived ingredients to treat asthma, ischemic heart disease, diabetes, ulcers, skin disease, and cancer.

    in acute oral studies using mice and rats. In parenteral studies, the LD(50) using mice was > 200 mg/kg, rats was > 50 mg/kg, and using dogs was > 50 mg/kg. In intravenous studies the LD(50) using mice was > 80 mg/kg, rats was > 15 mg/kg, and dogs was > 10 mg/kg. The 14-day no observed effect level (NOEL) for the Aloe polysaccharide, acemannan, in the diet of Sprague-Dawley rats, was 50,000 ppm or 4.1 to 4.6 g/kg day(-1). In a 3-month study using mice, Aloe vera (extracted in ethanol) given orally in drinking water at 100 mg/kg produced reproductive toxicity, inflammation, and mortality above that seen in control animals. Aloe vera extracted in methanol and given to mice at 100 mg/kg in drinking water for 3 months caused significant sperm damage compared to controls. Aloe barbadensis extracted with water and given to pregnant Charles Foster albino rats on gestational days (GDs) 0 through 9 was an abortifacient and produced skeletal abnormalities. Both negative and positive results were found in bacterial and mammalian cell genotoxicity assays using Aloe barbadensis-derived material, Aloe Ferox-derived material, and various anthraquinones derived from Aloe. Aloin (an anthraquinone) did not produce tumors when included in the feed of mice for 20 weeks, nor did aloin increase the incidence of colorectal tumors induced with 1,2-dimethylhydrazine. Aloe-emodin (an anthraquinone) given to mice in which tumor cells had been injected inhibited growth of malignant tumors. Other animal data also suggest that components of Aloe inhibit tumor growth and improve survival. Various in vitro assays also demonstrated anticarcinogenic activity of aloe-emodin. Diarrhea was the only adverse effect of note with the use of Aloe-derived ingredients to treat asthma, ischemic heart disease, diabetes, ulcers, skin disease, and cancer. Case reports include acute eczema, contact urticaria, and dermatitis in individuals who applied Aloe-derived ingredients topically. The Cosmetic Ingredient
