Summary
To investigate the suitability of the pig as animal model for postmenopausal osteoprosis, effects of ovariectomy (OVX) on bone metabolism and histology were studied in two groups of sows (9 months, nulliparous or 35 months, multiparous). A standard diet of about 1.5 % calcium (Ca) was fed till sacrifice at either 12 or 20 months post OVX when mineral content and histology were studied in representative bone specimens of proximal tibia, iliac crest and lumbar vertebrae. At 4, 8, 12, and 18 months post OVX, total and bone-specific alkaline phosphatase (APt, APb) calcidiol, calcitriol and parathyroid hormone (PTH) were measured in plasma.
In young sows OVX did not significantly affect plasma variables except for calcitriol, which was higher at 4 months post OVX. No significant differences between OVX or control animals were observed in the variables of bone chemical and histological analyses, neither 12 nor 20 months post OVX.
In multiparous sows OVX significantly increased PTH plasma concentrations at 8 months post OVX and plasma calcitriol, APt and APb at 12 months post OVX. All effects were moderate and transient. OVX did not significantly affect the variables of bone chemical and histological analyses neither 12 nor 20 months post OVX.
Although undoubtedly the clinical-chemical changes observed were not accompanied by any histomorphometric signs of osteopenia/osteoporosis, it must be left to future experiments as to whether this resulted from the ample calcium supply provided. This possibility is supported by recent observations showing that porcine osteopenia could be induced by OVX in animals maintained on only 0.75 % dietary calcium but not on higher (0.9 %) Ca regimens (33).
Zusammenfassung
In der vorliegenden Untersuchung sollte die Eignung des ovariektomierten Schweins als Modell für die postmenopausale Osteoporose beschrieben werden. Hierzu wurde der Einfluß der Ovariektomie (OVX) auf Plasmaparameter des Knochenstoffwechsels und auf knochenhistologische Parameter bei zwei Gruppen von Sauen (9 Monate alt, Nullipara oder 35 Monate alt, Multipara) untersucht. Eine Standarddiät für Schweine mit einem Calciumgehalt von 1,5 % wurde verabreicht. Gesamt-und knochenspezifische alkalische Phosphatase (APt, APb) Calcidiol, Calcitriol und Parathormon (PTH) wurden im Plasma 4, 8, 12 und 18 Monate nach OVX bestimmt. Der Mineralgehalt sowie histologische Parameter wurden in repräsentativen Knochenproben 12 Monate nach OVX und am Ende des Versuchs 18 Monate nach OVX gemessen.
Bei jungen Sauen führte die Ovariektomie zu keinen signifikanten Veränderungen der Plasmaparameter mit Ausnahme höherer Konzentrationen des Calcitriols 4 Monate nach OVX. Es wurden weder 12 noch 20 Monate nach OVX signifikante Unterschiede zwischen OVX- und Kontrolltieren in den Parametern der chemischen oder histologischen Knochenanalyse beobachtet.
Bei multiparen Sauen waren die Plasmakonzentrationen des PTH gegenüber den Kontrolltieren 8 Monate nach OVX signifikant erhöht. Die Konzentrationen des Calcitriols sowie die Aktivität der APt und APb lagen 12 Monate nach OVX signifikant über den Werten der intakten Tiere. Alle Effekte waren moderat. Weder 12 Monate noch 20 Monate nach OVX kam es zu signifikanten Veränderungen in den Parametern der chemischen oder histologischen Knochenanalyse.
Obwohl die beobachteten Veränderungen in den klinisch-chemischen Plasmaparametern zweifellos keine histomorphometrischen Anzeichen einer Osteopenie/Osteoporose zur Folge hatten, bleibt es zukünftigen Untersuchungen überlassen nachzuprüfen, ob das Ausbleiben des Osteopenie ein Ergebnis der in diesem Experiment hohen Calciumzufuhr war. Eine solche Möglichkeit sollte aufgrund der Beobachtung in Betracht gezogen werden, daß Osteopenie beim Schwein nach OVX eintritt, wenn eine Diät mit geringerer Calciumzufuhr (0,75 % im Vergleich zu 0,9 %) verabreicht wurde (33).
