CHEZ LA BREBIS, LA REGRESSION DES STRUCTURES LUTEALES ET LA CHUTE DE LA PROGESTERONE QUI SE PRODUISENT EN FIN DE CYCLE SONT DUES PRINCIPALEMENT A L'ACTION D'UN FACTEUR LUTEOLYTIQUE UTERIN: LA PROSTAGLANDINE F2 (PGF2). EN PRESENCE DE L'EMBRYON, LA LUTEOLYSE EST INHIBEE ET LE CORPS JAUNE EST DIT GESTATIF. L'ADMINISTRATION INTRAMUSCULAIRE OU INTRA-UTERINE D'UN INTERFERON TROPHOBLASTIQUE OVIN RECOMBINANT (R.OIFN-T) A DES BREBIS CYCLIQUES PERMET LE MAINTIEN DES STRUCTURES LUTEALES ET DE LA SECRETION DE PROGESTERONE EN INHIBANT LES SECRETIONS PULSATILES DE LA PGF2. ADMINISTRE PAR VOIE INTRA-UTERINE AUX MEMES DOSES, L'IFN- RECOMBINANT BOVIN (R.BIFN-) N'EST PAS CAPABLE D'INHIBER LA REGRESSION DU CORPS JAUNE. L'ADMINISTRATION INTRA-UTERINE EN UNE SEULE FOIS DE R.OIFN-T SUR DES SUPPORTS A EFFET RETARD TELS QUE LES LIPOSOMES OU DES MATRICES COVALENTES EST AUSSI EFFICACE DANS LE MAINTIEN DE L'ACTIVITE LUTEALE QUE LES QUANTITES INJECTEES QUOTIDIENNEMENT. L'OIFN-T N'EST PAS SUFFISANT POUR MAINTENIR SEUL L'ACTIVITE LUTEALE A 100%. AUSSI AVONS-NOUS TESTE L'EFFET D'UN AUTRE FACTEUR TROPHOBLASTIQUE, LE PAF, DANS L'INHIBITION DE LA LUTEOLYSE. LE PAF ADMINISTRE SEUL A DES BREBIS CYCLIQUES NE PROLONGE PAS L'ACTIVITE FONCTIONNELLE DU CORPS JAUNE ET, EN ASSOCIATION AVEC LE R.OIFN-T, IL N'AMELIORE QUE TRES LEGEREMENT L'EFFET DU R.OIFN-T. LES CORPS JAUNES SE MAINTIENNENT DE FACON VARIABLE CHEZ LES BREBIS TRAITEES PAR LE R.OIFN-T ET LEUR PERSISTANCE N'EXCEDE JAMAIS CELLE D'UN CORPS JAUNE GESTATIF. AUSSI AVONS-NOUS ANALYSE L'EFFET DE LA PRODUCTION D'OESTROGENE FOLLICULAIRE SUR CETTE VARIABILITE DE REPONSE INDIVIDUELLE. L'ADMINISTRATION CHRONIQUE DE BUSERELINE RESTE NEANMOINS SANS EFFET SUR LA PERSISTANCE DES CORPS JAUNES MAINTENUS PAR L'ADMINISTRATION DE R.OIFN-T. EN CONCLUSION, LES DIFFERENCES DE REPONSE INDIVIDUELLE AINSI QUE LA VARIABILITE DE LA PERSISTANCE DES CORPS JAUNES MAINTENUS PAR LE R.OIFN-T DEPEND D'AUTRES FACTEURS ENCORE MAL IDENTIFIES

Cost Recovery, Financing, and Comparison to NonFederal Utilities
The three Federal power marketing administrations (PMAS) -- the Southeastern Power Admin., the Southwestern Power Admin., and the Western Power Admin. -- transmit and sell electric power in 30 states that is generated mainly at Federal hydropower facilities. Collectively, in FY 1995, they had revenues of almost $1 billion. The power they sell is produced at 102 hydroelectric dams built and run by the Corps of Engineers and the Bureau of Reclamation. This report reviews these three PMAS' cost recovery practices, financing, and comparison to nonfederal utilities.

Bullying involves some three-quarters of a million children in the United Kingdom. For many victims the misery extends over many years and affects every day of their lives. Most people are aware of bullying yet the subject has been strangely ignored. This, the first major book devoted to bullying examines these questions: What is bullying? How does it happen? Who is likely to be involved? Where does it take place? What are the causes? And what can be done about it? The solutions offered independently by the contributors challenge the stereotype assumptions about bullies and victims and are essentially practical, suggesting strategies for establishing an ethos by which schools can become safe places for pupils, parents and teachers.
