HONG, SUK KI. (U. Rochester School Med. and Dentistry, Rochester, N. Y.) Effects of P’t ‘t z uz rin and cold on water exchanges of frogs. Am. J. PhysiO1. I 88(3): 439-442. rg57.-Net water transfer across the skin and urine formation by the kidneys were studied in frogs (R. @iens) especially under the influence of Pituitrin. The water uptake across the skin increased approximately 2.5-fold after...

© 1997 Journals of Reproduction and Fertility 1359-6004/97 $10.00 Early in this century, Sir Henry Dale reported that a substance in posterior pituitary extracts induced uterine contractions (Dale, 1909). In 1953, du Vigneaud and his colleagues published the sequence of this ‘oxytocic’ substance, demonstrating a nine amino acid peptide with a disulfide bond creating a ring structure (du Vigneau...

Those of us who study physiology are tempted to hope that the experimental perturbations which we induce affect only the organ which has ensnared our interest. This review uses physiological systems which incorporate oxytocin as models to indicate some of the ways in which departure from such investigative paradise occurs, and also to discuss some of the implications of a physiology which uses ...

BACKGROUND: Postpartum haemorrhage is a major cause of maternal death in underdeveloped countries like India, and to prevent and treat PPH is of major public health importance. AMTSL is a preventive measure and when practiced routinely, can reduce hemorrhage by up to 60 %. The aim of the present study was to evaluate the role of misoprostol in active management of the third stage of labour and ...

THE physiologic changes of pregnancy, including an initial gradual increase in cardiac output, followed by the development of increasing aortocaval compression in the third trimester, as well as comorbidities such as preeclampsia, have generated considerable research into maternal hemodynamics. The use of the pulmonary artery catheter allowed a better understanding of the physiology of the heal...
