前言为了避免生育过多过密影响母子健康,计划生育及避孕药物的研究有着极其重要的意义,近年来在党和政府号召下,卫生部门和科学工作者曾做了很多研究,取得了不少成绩。目前国内外避孕方法不外乎是采用机械方法和外用药,虽有一定效果,但使用不便,有时甚至引起象子宫炎等付作用,因此研究更简便而又可靠的口服避孕药有其特殊的价值。我们根据1959年翁帼英等的研究选用经动物试验有良好避孕效果的苦丁茶和枸骨作更深入一步的研究——动物疗效试验,机转探讨和有效成份提取。苦丁茶和枸骨嫩叶在江都县都称苦丁茶,经我院药材教研组鉴定是不同的品种,苦丁茶为大叶冬青,学名Ilex leactifolia Thunb产于长江下游及浙江、福建一带。枸骨(江都,南京货)系冬青科植物枸骨Ilex Corunta lindley的干燥叶产于浙江,安徽、湖北等省。
Foreword In order to avoid excessive fertility affecting maternal and child health, research on family planning and contraceptives is extremely important. In recent years, under the call of the party and the government, the health department and scientists have done a lot of research and made a lot of research. Achievements. At present, the contraceptive method at home and abroad is nothing more than the use of mechanical methods and external medicine. Although it has certain effects, it is inconvenient to use, and sometimes it even causes effects such as metritis. Therefore, the study of more convenient and reliable oral contraceptives has its special value. According to the study of Weng Yuying et al. in 1959, we used kudingcha and cheekbones that have been tested for good contraceptive efficacy in animals for more in-depth studies—animal efficacy trials, machine-to-study studies, and effective ingredient extraction. Kuding tea and young leaves of cheekbones are known as Kuding tea in Jiangdu County. They are identified by the Institute of Chinese Medicinal Materials as a different species. Kudingcha is a large-leaved holly, and the scientific name Ilex leactifolia Thunb is produced in the lower reaches of the Yangtze River and in Zhejiang and Fujian. The tibia (Jiangdu, Nanjing) is the dry leaf of Ilex Corunta lindley of the holly plant. It is produced in Zhejiang, Anhui and Hubei provinces.
