“…The domesticated small ruminants are becoming increasingly popular as laboratory animals both in physiological investigations and in the study of long term pharmacological actions of drugs (EDJTEHADI, 1977;MOSTAGHNI and HOWARD, 1975). Clinical pathology studies of these animals require detailed information concerning their hematological values.…”

Summary Blood samples from 150 apparently healthy goats of different ages were studied to observe normal hematological values and their changes from birth to 5 years of age. After an initial decrease during the first week of life, the mean values of RBC, PCV and WBC rose to attain peak values at 2 to 6 months; they then fell at 8 to 10 months and remained stationary. Hb and MCH values also fell in the first month of life, but thereafter stabilized. Neutrophil counts were low at birth but increased during the first week of life. The values were maintained for 2 years and were then followed by an increase to a highest value at 5 years. The changes in neutrophil counts were inversely related to changes which were observed in the lymphocytes counts. There were no changes in monocyte, eosinophil, basophil, platelet and MCHC during the period of observation. Poikilocytosis was observed but mostly in the early stages of life, whereas anisocytosis was observed independent by of age. Zusammenfassung Altersabhängige Veränderungen des Blutbildes der Ziegen Bei 150 klinisch gesunden Ziegen verschiedenen Alters (neugeboren bis 5 Jahre alt) wurden die Blutwerte bestimmt. Nach Senkung während der ersten Lebenswoche erhöhten sich die Erythrozytenzahl (RBC), der Haematokritwert (PCV) und die Leukozytenzahl (WBC). Diese Parameter erreichten im zweiten bis sechsten Monat die höchsten Werte, dann fielen sie bis zum achten bzw. zehnten Monat etwas ab und blieben dann konstant. Auch der Hämoglobingehalt (Hb) und der Färbekoeffizient (MCH) fielen während des ersten Monats, blieben aber nachher konstant. Die Zahl der neutrophilen Granulozyten war bei der Geburt niedrig, erhöhte sich jedoch während der ersten Lebenswoche. Die Werte blieben dann während 2 Jahre stationär und erhöhten sich in der Folge bis zum 5. Jahr. Die Neutrophilenzahl verhielt sich umgekehrt proportional zur Lymphozytenzahl. Die Monozyten, Eosinophilen, Basophilen, Thrombozyten und die mittlere Hb‐Konzentration der Erythrozyten (MCHC) veränderten sich während der Beobachtungsperiode nicht. Eine Poikilozytose wurden vorwiegend in den früheren Lebensphasen festgestellt, die Anisozytose zeigte hingegen keine Altersabhängigkeit. Résumé Modifications liées à l'âge de l'image sanguine chez des chèvres On a déterminé les valeurs sanguines chez 150 chèvres cliniquement saines d'âges différents (de la naissance à 5 ans). Après un abaissement durant les premières semaines de vie, le nombres des érythrocytes, la valeur de l'hématocrite et le nombre des leucocytes a augmenté. Ces paramètres ont atteint les valeurs les plus élevées du deuxième au sixième mois pour baisser un peu de huitième au dixième et rester constants par la suite. Le taux d'hémoglobine et le coefficient de coloration diminuèrent également durant le premier mois pour rester constant par la suite. Le nombre des granulocytes neutrophiles fut bas à la naissance et augmenta durant les premières semaines de vie. Les valeurs restèrent stables pendant 2 ans et augmentèrent ensuite jusqu'à la cinquième année. Le nombre...

A shielded silver electrode was fixed to the abdominal vagus nerve in the lesser curvature of the abomasum and the leads were exteriorized through the abdominal wall.…”

“…Duodenal infusion of HCl reduces, and of alkali increases gastric output in milk-fed calves (Bell & Mostaghni, 1975). It has also been reported that duodenal infusion of HCl in sheep initially stimulates and then inhibits duodenal motility (Mostaghni & Howard, 1975) while it has recently been suggested that continuous infusion of alkali to the duodenum increases the rate of MMC in sheep (Bueno & Fioramonti, 1979).…”

In three experiments 2 #g ACTH potentiated the inhibitory effects of morphine.This opiate-like action of ACTH was even more apparent at higher doses. The pressure response to hypertonic sodium chloride was substantially reduced and in one case completely abolished by 10 jug ACTH (n = 3) in the absence of morphine, an effect that was antagonized by naloxone.These experiments show that opiate inhibition of the release of neurohypophysial hormones may be attenuated by low doses of ACTH. At higher doses ACTH appears to have an opiate-like action. This suggests that the effects ofACTH and endorphin-like peptides on the release of neurohypophysial hormones may depend upon their relative concentrations -perhaps as a consequence of the differential processing of their common precursor.
