A review of antifertility folkloric plants tested in laboratory animals

The use of natural active principals is widespread among a great proportion of the rural population, or by people who do not have easy access to medical assistance. These active principles are used as food or medicines, and even for purposes of contraception. It becomes necessary to establish a relationship between the folklore habits and current information on the nature of anti-fertility substances, and knowledge of their mechanisms. Anti-fertility agents may exert their actions in a number of areas, (hypothalamus, anterior pituitary, oviduct, uterus, and vagina), inhibiting synthesis and/or liberation of hormones (follicle-stimulating, luteinizing, and steroid hormones), ovulation, ovum transportation, and implantation process. Therefore, a review of literature was carried out, including of several plants used by women as abortifacient and anti-fertility agents to compare their effects with those obtained among laboratory animals.

中国蒿属（Artemisia L.）花粉形态研究--兼论与其邻近属花粉形态的关系

本文利用电子显微镜和光学显微镜研究了国产的蒿属花粉代表种和常见种共66种4变种，根据花粉外壁纹饰可将其分为六大类型：1、具刺状突起，排列不密集，刺间具颗粒状纹饰（类型—I）。2、刺状突起较类型—I稍为密集，没有或有少许颗粒状纹饰（类型—II）。3、具刺状突起，排列不密集，但刺间无颗粒状纹饰，较粗糙（类型—III）。4、刺状突起较类型—I稍为密集，刺间具发育的小芽胞状或颗粒状纹饰，小芽孢状突起顶部有的还可见有一小穿孔存在（类型-IV）。5、具微刺状突起，排列极稀，刺间较为平滑（类型—V）。6、刺状突起有大小之分，大刺较尖，还有颗粒状纹饰（类型—VI）。其中类型—I占绝对优势，其次为类型—II，类型—V和类型VI为较特殊的类型。 本文还对蒿属邻近属（即蒿自然群中的其它属）各属代表种花粉作了详细的研究，并和蒿属花粉作了比较。结果表明：按外壁纹饰可将蒿自然群分为两大类型：1、具明显的刺状纹饰。其中包括：亚菊属、女蒿属、百花蒿属。2、具退化状小刺。其中包括：蒿属、茶蒿属、线叶菊属、画笔菊属、喀什菊属、栉叶蒿属、绢蒿属。经研究我们认为在花粉形态上蒿自然群是一相互关联的有机整体，并从花粉形态的角度出发，文中讨论了紊蒿属和百花蒿属的分属问题，作者认为它们独立成两个单种属的意见较为妥当。
