The efficacy of transcervical insertions of quinacrine hydrochloride pellets to produce tubal occlusion has been evaluated in a study of 139 women in Santiago, Chile. At one year, the pregnancy rate was 3.1%, an acceptable rate for a nonsurgical method of female sterilization.
The efficacy and tolerability of 80 mg propranolol tablets as a vaginal contraceptive were studied in 198 fertile women for 11 months. The calculated one year life table pregnancy rate was 3.4/100 women and the Pearl index was 3.9/100 women years. No major adverse effects were encountered. The findings suggested that propranolol is an effective vaginal(More)
Extensive research has been undertaken to develop a simple method of non-surgical female sterilization. Zipper and associates identified quinacrine hydrochloride as a drug likely to produce tubal occlusion when placed into the uterus. Zipper's early work with a solution of quinacrine led to the development of quinacrine pellets, a delivery system that was(More)
Abal~ct We have studied electron heating in a 2DEG in GaAs/AIGaAs heterojunctions below 0.5 IC The electron temperature was raised above the lattice temperature using Joule heat/n& Weak localiT~tion and the temperature-dependent sample resistance were used as thermometers for the electrons. The electron-phonon energy relaxation rate was found to be(More)
It is 15 years since Corfman reviewed transcervical oviduct occlusion and chronicled the history of the concept. * In 1849 a technique was developed to produce tubal occlusion with the application of silver nitrate to the cornua. Many other agents have since been evaluated for their tubal occlusive capabilities , such as zinc, phenol, chloride, sodium(More)
