- W2018949095 abstract "Inhalt Um die mogliche atiologische Rolle eines β-Carotinmangels fur die Genese von Follikel-Lutein-Zysten des Rindes abzuklaren, wurden Geschlechtsorgane und Blutproben am ortlichen Schlachthof gesammelt. Die β-Carotinkonrentrationen wurden in Petrolatherextrakten uon Blutserum- und verseiften Luteingewebeproben, die von Rindern mit solchen Zysten oder mit zyklischen Gelbkorpern stammten, photometrisch bestimmt. Die mittlere β-Carotinkonzentration im Serum von 12 zystentragenden Tieren war signifikant niedriger als bei 12 Tieren mit zyklischen Gelbkorpern (0,7 ± 0,5 us. 2,2 ± 1,4μg/ml; p ≤ 0,01). Die mittleren β-Carotinkonzentrationen im Luteingewebe progesteronproduzierender Follikel-Lutein-Zysten und Gelbkorper unterschieden sich nicht signifikant (11,7 ± 13,6 vs. 8,7 ± 10,6 μg/g; p > 0,05; n = 5, n = 6). Die β-Carotinkonrentrationen im Luteingewebe und im Blutserum von Tieren mit progesteronserernierenden Zysten und Gelbkorpern waren signifikant positiv korreliert (r = 0,61 und r = 0,81; p ≤ 0,01). Die Ergebnisse sprechen fur eine wichtige Bedeutung des β-Carotinmangels bei der Entstehung von Follikel-Lutein-Zysten beim Rind.Contents: β-carotene and luteinized follicular cysts in cattle To evaluate the possible etiological role of β-carotene deficiency in the genesis of luteinired follicular cysts in the bovine, genital organs and blood were obtained from the local abattoir. β-carotene concentrations were quantified photometrically in petrolether extracts of blood serum and saponified luteal tissue of dairy cattle bearing such cysts or cyclic corpora lutea. The mean serum β-carotene concentrations of 12 cyst bearing animals were significantly lower than in 12 animals having cyclic corpora lutea (0. 7 ± 0.5 us. 2.2 ± 1.4 μg/ml; p ≤ 0.01). Luteal tissue β-carotene concentrations of progesterone secreting luteinired follicular cysts and cyclic corpora lutea did not differ significantly (11.7 ± 13.6 us. 8.7 ± 10.6 μg/g; p> 0.05; n = 5, n = 6 respectively). Luteal tissue and serum β-carotene concentrations were positively correlated in animals bearing progesterone secreting cysts or corpora lutea (r = 0.61 and r = 0.81; p ≤ 0.01; respectively). Results suggest a causative role of β-carotene deficiency in the genesis of luteinired follicular cysts in cattle." @default.
