Radioimmunologische Bestimmung physiologischer Östrogenkonzentrationen im Blutplasma von Kühen um den Geburtstermin

Abstract: Inhalt: Bei 11 Kühen der Rasse Deutsches Schwarzbuntes Rind wurde um den Geburtstermin der Östrogenspiegel im Blutplasma radioimmunologisch bestimmt. Die Blutproben wurden von etwa vier Tagen ante partum bis zu einem Tag post partum zweimal täglich über einen Dauerkatheter aus der V. jugularis entnommen. Alle Versuchstiere kalbten nach einer physiologischen Tragezeit von 274 bis 285 Tagen normal ab und zeigten um den Geburtstermin keine klinischen Erkrankungen. Für die Bestimmung der immunologisch nachweisb… Show more

“…For the determination of the immunoreactive oestrogens, rabbit antibodies against 17/?-oestradiol-4-azo-BSA with equal binding affinity to both oestrone and oestradiol-17ß were used. No cross-reaction with oestradiol-17a was observed (Agthe & Kolm, 1975). Progesterone determinations were carried out according to the method described by Abraham, Swerdloff, Tulchinsky & Odell (1971), using antibodies against progesterone-11-hemisuccinate-BSA.…”

“…-Hormonal assays:  Oestrogen and progesterone: They were determined by radioimmunoassay (RIA) by using RIA kits (DPC, Diagnostic corporation, Los Angelus) at Atomic Energy Authority using the method of Abraham (1977), Agthe and Kolm (1975) respectively. -Biochemical analysis:  Total protein, albumin and globulin: They were estimated by using atomic absorption spectrophotometer (Perkin Elemr model 3300, USA) according to Grant, et al, (1987).…”
