INTRODUCTION Some conditions require induction of parturition: colic, severe hyperlipemia, prepubian tendon rupture, premature placental separation, hydroallantoïd, and foetal distress2,4,5. Prolonged gestation is not a good indication1,4. Protocols using oxytocin, prostaglandins or corticosteroids can induce parturition2,3,4,5. Most induction protocols use low doses of oxytocin2,3,5. OBJECTIVE On the basis of a clinical case, this poster will discuss the indications, the methods and the risks of parturition induction in the mare. CLINICAL CASE A pony mare at day 310 of pregnancy is presented for colic with poor prognosis. The foetal parameters are good and the cervix begins to open. There is no milk in the udder. The decision to save the foal is taken and parturition is induced by one oxytocin bolus (20 I.U./IV) followed by an oxytocin infusion (100 I.U. in 1000ml saline). After assisted foaling, the foal rises and sucks commercial colostrum within 30 minutes. Soon, the foal becomes depressed and, despite treatment with commercial plasma, tube feeding and antibiotics, dies at day 2. DISCUSSION This case required immediate induction of foaling, which was achieved by administration of high doses of oxytocin. Commonly, high doses of oxytocin induce dystocia because the foal has no time to move to correct (dorso-sacral) presentation1,2,5. The risks for the foal include absence of colostrum and foetal immaturity1,2,3,4,5. Even after day 300, the prognosis is poor1,2,3,4. A good prognostic indicator of the foal’s maturity (lung, and other systems) is the electrolytes concentration in the mother’s milk2,4. These protocols should be used when foetal maturity is ascertained or as last resort1,2,3,4. CONCLUSIONS Foaling induction is risky for dystocia and foal outcome. It should be reserved to cases where foal’s maturity can be assessed. [less ▲]

Three parvalbumin isotypes were isolated from the white muscle of haemoglobin-myoglobin-free antarctic fish Channichthys rhinoceratus. Antibodies against the parvalbumin mixture were raised in rabbits and used for discovery, quantitation and isolation by affinity chromatography of parvalbumin in the cardiac muscle of three antarctic fish species: Channichthys rhinoceratus, Champsocephalus gunnari and Notothenia neglecta. The cardiac muscle of these species contains parvalbumin in concentration close to 1 mumol per kg wet weight. [less ▲]

Five parvalbumins have been isolated from the white muscles of the lungfish. They can be divided into two sub families showing typical amino acid compositions, C-terminal amino acid residues, peptide maps and immuno-reactivity. The red muscles including the cardiac muscle also contain parvalbumins in amounts roughly inversely related to the concentration of myoglobin in the muscle. Parvalbumins have also been detected in the brain and kidney. [less ▲]

Vasotocin (VT; the antidiuretic hormone of birds) is synthesized by diencephalic magnocellular neurons projecting to the neurohypophysis. A sexually dimorphic system of VT-immunoreactive (ir) parvocellular elements has been described within the male medial preoptic nucleus (POM) and the nucleus of the stria terminalis, pars medialis (BSTm). VT-ir fibers are present in many diencephalic and extradiencephalic locations, and quantitative morphometric analyses demonstrated their sexually dimorphic distribution in regions involved in the control of different aspects of reproduction. Moreover, systemic or intracerebroventricular injections of VT markedly inhibit the expression of some aspects of male sexual behavior. In adult animals, circulating levels of testosterone (T) have a profound influence on the VT immunoreactivity within BSTm, POM, and lateral septum. Castration markedly decreases the immunoreaction, whereas T-replacement therapy restores a situation similar to the intact birds. We observed no changes in gonadectomized females treated with T. These changes parallel similar changes in male copulatory behavior (not present in castrated male quail, fully expressed in castrated, T-treated males). The restoration by T of the VT immunoreactivity in castrated male quail could be fully mimicked by a treatment with estradiol (E-2), suggesting that the aromatization of T into E-2 may play a key limiting role in both the activation of male sexual behavior and the induction of VT synthesis. This dimorphism has an organizational nature: administration of E-2 to quail embryos (a treatment that abolishes male sexual behavior) results in a dramatic decrease of the VT immuno reactivity in sexually dimorphic regions. Conversely, the inhibition of E-2 synthesis during embryonic life (a treatment that stimulates the expression of male copulatory behavior in treated females exposed in adulthood to T) results in a malelike distribution of VT immunoreactivity. The VT parvocellular system of the Japanese quail can therefore be considered an accurate marker of the sexual differentiation of brain circuits mediating copulatory behavior and could be a very sensitive indicator of the activity of estrogenlike substances on neural circuits.

Les ichthyosaures sont un groupe diversifié de reptiles marins mésozoïques. Pour de nombreux auteurs, trois extinctions majeures ont perturbé leur longue histoire évolutive : une à la fin du Trias, une à la limite Jurassique–Crétacé (JCB) et une (résultant en l’extinction totale) à la limite Cénomanien–Turonien. On croyait que l’extinction de la JCB avait éradiqué la plupart des morphotypes particuliers trouvés dans le Jurassique supérieur, à la faveur de quelques formes crétacées considérées moins spécialisées. Ici, nous réévaluons cette hypothèse en utilisant des analyses phylogénétiques et des taux de cladogenèse/survie/extinction. Notre analyse phylogénétique indique que les ophthalmosauridés (clade unissant tous les ichtyosaures post-bajociens) ont divergé très tôt dans leur histoire en deux clades distincts ; tous deux traversent la JCB et persistent au moins jusqu’ à l'Albien terminal. Pour évaluer l'effet de l'extinction de la JCB sur les ichthyosaures, nous avons calculé des taux de cladogenèse, d'extinction, et de survie pour chaque étage de l'intervalle Oxfordien-Barrémien, selon différents scénarii. Le taux d'extinction de la JCB ne surpasse pas le taux « background » pour l'intervalle Oxfordien-Barrémien et la JCB enregistre un des taux de survie le plus élevé de l'intervalle. Par conséquent, il n'existe actuellement aucune preuve que les ichthyosaures aient été touchés par une extinction à la JCB, contrairement à de nombreux autres groupes d’animaux marins. Les ophthalmosauridés restent diversifiés de leur rayonnement rapide au Jurassique moyen jusqu’à leur extinction totale au début du Crétacé supérieur. [less ▲]
