Videolaparoscopy was used to visualize the reproductive tract contractility of the squirrel monkey, Saimiri sciureus. This technique gives information on the nature, direction of propagation, duration, and frequency of contractions. At the times of ovulation, and embryo entry to the uterus, contractile activity was observed in both the uterus and oviduct, with the latter being more frequent. The dominant direction of propagation was towards the utero-tubal junction, and simultaneous contractions were frequently observed in both uterus and oviduct. © 1992 Wiley-Liss, Inc.  相似文献

Detergents containing either a cholic acid, a deoxycholic acid, or an octanoic acid-like hydrophobic moiety and a bisgluconamidopropyl polar group were synthesized. Extinction coefficients, partial specific volumes, critical micelle concentrations, and aggregation numbers were determined for each of the detergents. The two bile acid derivatives are capable of solubilizing functional opiate receptor, while the octanoic acid derivative is not.  相似文献
